Description
技术领域 technical field
本发明涉及一种农田低压管道输水灌溉系统的附属配件，具体涉及一种农田低压输水管道旋盖防冲式定额取水口，属于农田管道输水灌溉工程技术领域。 The invention relates to an accessory accessory of a farmland low-pressure pipeline water delivery irrigation system, in particular to a farmland low-pressure water delivery pipeline screw cap anti-scouring fixed fixed water intake, which belongs to the technical field of farmland pipeline water delivery irrigation engineering.
背景技术 Background technique
低压管道输水灌溉系统的取水口是从管道到农田配水的重要设施，取水口处水流形态直接影响到取水设施的稳定性以及对农田土壤的冲刷程度，甚至会影响到先进灌水技术的推广应用。随着农田灌溉用水管理条件将逐渐趋于一致，取水设施防冲技术将越来越具有研究和推广应用价值，已逐步受到人们的重视。 The water intake of the low-pressure pipeline water delivery irrigation system is an important facility for water distribution from the pipeline to the farmland. The water flow pattern at the water intake directly affects the stability of the water intake facility and the degree of erosion of the farmland soil, and even affects the popularization and application of advanced irrigation technology. . As the water management conditions for farmland irrigation will gradually become the same, the anti-scour technology of water intake facilities will have more and more research and application value, and has gradually attracted people's attention.
取水口是低压输水灌溉管道的一个重要组成部分。由于管道输水系统对地形的适应性，系统的压力分布对明渠系统差异较大，水量的调节、控制要求较高，所以其中的取水口引起了人们更多的关注。 The water intake is an important part of the low-pressure water delivery irrigation pipeline. Due to the adaptability of the pipeline water delivery system to the terrain, the pressure distribution of the system is quite different from that of the open channel system, and the regulation and control of water volume are more demanding, so the water intake has attracted more attention.
对于既有防冲功能又能稳定配水的定额取水设施的研究我国处于起步阶段，尚没有成熟的理论和产品问世。目前使用的取水设施对于管道系统出水量的调节和控制能力都较差，导致水流对农田土壤的冲刷问题较为显著，系统的水量分配和用水管理也十分麻烦。为此，为了适应当前农田灌溉用水管理的要求，实时准确地给农田提供需要分配的水量，开发研制与管道系统相配套的定额取水口则非常必要而十分迫切。这是减少出水防冲、提高田间水有效利用率、提高灌水均匀度以及达到设计灌水定额等的关键。 The research on quota water intake facilities with anti-scour function and stable water distribution is still in its infancy in my country, and mature theories and products have not yet come out. The water intake facilities currently in use are poor in regulating and controlling the water output of the pipeline system, resulting in significant erosion of the farmland soil by the water flow, and the water distribution and water management of the system are also very troublesome. For this reason, in order to meet the current requirements of farmland irrigation water management and provide real-time and accurate water distribution for farmland, it is very necessary and urgent to develop a fixed water intake that matches the pipeline system. This is the key to reducing water outflow and anti-scouring, improving the effective utilization rate of field water, improving the uniformity of irrigation, and reaching the design irrigation quota.
发明内容 Contents of the invention
本发明的目的是针对上述现有技术的不足，提供一种既能防冲又能定额配水的农田低压输水管道旋盖防冲式定额取水口。 The object of the present invention is to address the above-mentioned deficiencies in the prior art, and to provide an anti-scour type quota water intake of a farmland low-pressure water delivery pipeline that can not only prevent scour but also distribute water at a fixed rate.
本发明的目的是通过以下技术方案实现的：农田低压输水管道旋盖防冲式定额取水口，包括低压输水管道，其特征是，设有进水区、出水区和防冲装置，防冲装置设置在出水区内，进水区分别与低压输水管道和防冲装置连接，所述进水区由立管、异径三通连接构成，异径三通安装在低压输水管道分支处，所述防冲装置是由旋盖、圆筒形连接座构成，旋盖内侧的盖顶中部设有螺杆，所述连接座套置连接在立管上，连接座中心设有与螺杆相匹配的螺纹安装座，旋盖通过螺杆、螺纹安装座与连接座螺纹连接，所述螺杆底部设有防止螺杆滑出螺纹安装座的定位销。 The object of the present invention is achieved through the following technical solutions: farmland low-pressure water pipeline screw cap anti-scour type fixed water intake, including low-pressure water pipeline, is characterized in that it is provided with water inlet area, water outlet area and anti-scour device, anti-scour The flushing device is set in the water outlet area, and the water inlet area is respectively connected with the low-pressure water delivery pipeline and the anti-washing device. The water inlet area is composed of a standpipe and a tee connection with a different diameter. The anti-shock device is composed of a screw cap and a cylindrical connecting seat. A screw is provided in the middle of the top of the inner side of the screw cap. The connecting seat is sleeved and connected to the standpipe. The matching threaded mounting seat, the screw cap is threadedly connected with the connecting seat through the screw rod, the threaded mounting seat, and the bottom of the screw rod is provided with a positioning pin to prevent the screw rod from slipping out of the threaded mounting seat.
所述连接座内壁和立管外壁之间胶结连接。 The connection between the inner wall of the connecting seat and the outer wall of the riser is glued.
所述旋盖为圆形，旋盖顶部的内径大于连接座的外径。 The screw cap is circular, and the inner diameter of the top of the screw cap is larger than the outer diameter of the connecting seat.
所述旋盖、螺杆、定位销、连接座为金属材料制成。 The screw cap, screw rod, positioning pin and connecting seat are made of metal materials.
所述旋盖内侧顶部设有密封垫，密封垫为橡胶材料制成。 A sealing pad is provided on the inner top of the screw cap, and the sealing pad is made of rubber material.
本发明上部为一个圆形旋盖，旋盖内侧中间固定有一根螺杆，下部是一个用于连接立管和旋盖的圆筒形连接座。由于旋盖顶部的内径大于连接座的外径（从而形成出水口），反向延伸的旋盖外侧壁使出水水流与进水水流方向相反，通过在立管上外套旋盖，取水口底座能消除水流多余能量。同时通过旋转旋盖可调节出水口过水断面的大小从而与已定的配水流量相对应。 The upper part of the present invention is a circular screw cap, a screw rod is fixed in the middle of the inner side of the screw cap, and the lower part is a cylindrical connecting seat for connecting the standpipe and the screw cap. Since the inner diameter of the top of the screw cap is larger than the outer diameter of the connection seat (thus forming a water outlet), the outer wall of the screw cap extended in the opposite direction makes the direction of the outlet water flow opposite to that of the water inlet flow. By putting the screw cap on the standpipe, the water intake base can Eliminate excess energy from water flow. At the same time, the size of the cross section of the water outlet can be adjusted by rotating the screw cap so as to correspond to the determined water distribution flow.
直接旋转旋盖可以自动调节出水口过水断面的大小，不同规格型号的取水口与所在管道上的位置和配水流量对应。利用外套旋盖的水力反冲原理消除管道富余压力水头，避免在取水过程中，水流直接冲刷农田土壤导致对取水设施的破坏。定位销可以防止旋盖在使用过程脱落，同时定位销位置决定了螺杆长度和旋盖最大开度，保证不同位置上的取水口配水流量一定，很好地解决了用水管理中取水口防盗与定额配水的问题，保证了灌溉区域上配水的均匀度。本发明的旋盖、螺杆设计与其它压板式取水口相比，止水效果更好，结构合理，水流平稳，反冲效果显著。 Directly rotating the screw cap can automatically adjust the size of the water outlet section, and the water intakes of different specifications and models correspond to the positions on the pipelines and the water distribution flow. Use the hydraulic recoil principle of the jacket screw cap to eliminate the excess pressure head of the pipeline, and avoid the damage to the water intake facilities caused by the water flow directly scouring the farmland soil during the water intake process. The positioning pin can prevent the screw cap from falling off during use. At the same time, the position of the positioning pin determines the length of the screw and the maximum opening of the screw cap, ensuring a constant flow of water at the water intake at different positions, which is a good solution to the anti-theft and quota of the water intake in water management. The problem of water distribution ensures the uniformity of water distribution in the irrigation area. Compared with other pressure plate type water intakes, the design of screw cap and screw rod of the present invention has better water stop effect, reasonable structure, stable water flow and remarkable recoil effect.

农田低压输水管道旋盖防冲式定额取水口，包括低压输水管道、进水区、出水区6和防冲装置，防冲装置设置在出水区内，进水区分别与低压输水管道和防冲装置连接。 Farmland low-pressure water delivery pipeline screw cap anti-scouring fixed quota water intake, including low-pressure water delivery pipeline, water inlet area, water outlet area 6 and anti-scouring device, the anti-scourr Connect with anti-shock device.
进水区由立管8、异径三通7连接构成，异径三通安装在低压输水管道分支处。防冲装置是由旋盖5、圆筒形连接座4构成，旋盖内侧的盖顶中部设有螺杆1，连接座套置连接在立管上，连接座内壁和立管外壁之间胶结连接。
The water inlet area is composed of a standpipe 8 and a tee with a different diameter 7, and the tee with a different diameter is installed at the branch of the low-pressure water pipeline. The anti-shock device is composed of a
连接座4中心设有与螺杆相匹配的螺纹安装座9，旋盖通过螺杆、螺纹安装座与连接座螺纹连接，螺杆底部设有防止螺杆滑出螺纹安装座的定位销3。
The connecting seat 4 center is provided with the threaded
旋盖为圆形，旋盖顶部的内径大于连接座的外径，从而形成出水口。旋盖内侧顶部设有密封垫2。旋盖、螺杆、定位销、连接座为金属材料制成，密封垫为橡胶材料制成。 The screw cap is circular, and the inner diameter of the top of the screw cap is larger than the outer diameter of the connecting seat, thereby forming a water outlet. A sealing gasket 2 is provided on the inner top of the screw cap. The screw cap, screw rod, positioning pin and connecting seat are made of metal material, and the sealing gasket is made of rubber material.
水流流过立管，从螺纹安装座的空隙流出，由于旋盖顶部的内径大于连接座的外径，反向延伸的旋盖外侧壁使出水水流与进水水流方向相反，通过转动旋盖带动螺杆在螺纹安装座中上下移动从而调节开度。 The water flows through the standpipe and flows out from the gap of the threaded mounting seat. Since the inner diameter of the top of the screw cap is larger than the outer diameter of the connecting seat, the outer wall of the screw cap extending in the opposite direction makes the direction of the outlet water flow opposite to the direction of the water inlet flow, and is driven by turning the screw cap. The screw moves up and down in the threaded mount to adjust the opening.
