Abstract
The utility model relates to a safety valve with multiple end openings. The end of the valve body is provided with a flange, and a valve plate on the top end of the valve body is provided with two or more end openings. The end opening is connected with a valve tube, and a valve core contacts the end opening in the valve tube. The upper part of the valve tube is provided with a sieve plate hole, and a compression spring is arranged between the sieve plate hole and the valve core. The inside of the valve body is provided with an inner valve core, and the inner valve core is connected with a rotary mechanism. Outside the valve body, the rotary mechanism is provided with an operation hand wheel. The valve body is connected with a pressure container., and the valve tube connected with the valve body seals the end opening arranged under the normal condition. When the pressure in the pressure container reaches the limited value, the valve core in the valve tube of the safety valve springs to remove excessive air for reducing the pressure in the container and ensuring the production safety. When one valve tube can not reach use requirements, the inner valve core can be rotated to cause the inner valve core to seal the end opening in the valve body. Under the condition of reaching the use requirements, the utility model is provided with multiple end openings. The disassembly and repair can be carried out without shutdown, and multiple end openings are simultaneously suitable for different discharge amounts.
Description
Technical field
The utility model relates to a kind of safety valve.
Background technique
In chemical industry, particularly in the production of inflammable and explosive product, the employed safety valve of pressurized container when damaging or not reaching usage requirement, needs to stop and changes.Change safety valve, not only need to stop to produce, and pressurized container need be suppressed again, adjusting process, waste of manpower, material resources, financial resources.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of under not parking situation maintainable safety valve, simple in structure, easy for installation.
Multiport safety valve of the present utility model, the end that it is characterized in that valve body has flange, have the port more than 2 or 2 on the valve plate on valve body top, be connected with valve cylinder on the port, what contact with port in the valve cylinder is spool, and valve cylinder top has the sieve plate hole, it between sieve plate hole and the spool pressure spring, one inner spool is set in the valve body, and inner spool connects rotating mechanism, and rotating mechanism has the operator wheel outside valve body.
Valve body is connected on the pressurized container, and with the port sealing that is provided with, the pressure in the valve cylinder is set the back and passed through fixedly pressure spring of sieve plate hole under the valve cylinder normal condition that connects on the valve body.When the pressurized container internal pressure reached limit value, too much gas was got rid of in the spool take-off in the safety valve valve cylinder, to reduce container internal pressure, guaranteed production safety.When a certain valve cylinder does not reach usage requirement, by rotate inner spool make inner spool in the valve body with this port sealing, inner spool fits snugly on the port because of the effect of the container internal pressure that is stressed.Therefore the utility model is provided with multiport reaching under the situation of usage requirement, does not need to stop can dismantle, keep in repair.Multiport is suitable for different discharge amounts simultaneously, so the quantity of port can design according to demand.
The rotating mechanism that connects on the inner spool can be the mode of various prior arts, its effect is to drive inner spool to rotate, below provide a kind of mode: form by rotatingshaft, transverse axis, latch plate, umbrella gear, handwheel, be positioned at the outer handwheel of valve body and connect umbrella gear, umbrella gear connects rotatingshaft, rotatingshaft is connected with inner spool by transverse axis, and rotatingshaft is connected latch plate with valve core chamber.
Valve cylinder of the present utility model also has the effect that reduces liquid entrainment, avoids pressure release impairment of qi and other people.On valve cylinder, can connect the back-fire relief pipe, have valve on the back-fire relief pipe, convenient toward the interior inert gas of filling of valve cylinder, avoid the inflammable gas in the valve cylinder to catch fire.
Advantage of the present utility model:
1, modern design, with low cost, manufacturing process is simple, and is convenient for installation and maintenance, and valve cylinder can be dismantled in working environment easily, suppresses in order to valve cylinder, and needn't stop, and has convenience, timely, characteristics of high efficiency, the alternative existing safety valve that uses.
2, can manufacture and design by NBS, be used with various pressurized containers easily, applied widely, the interchangeability height.
3, can manufacture and design according to user's request, the pressure setting range is wide, can form batch process, forms to make series.
4, multiport is suitable for different discharge amounts.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 7 umbrella gear, 8 rotatingshafts, 9 transverse axis, 10 pressure springs, 11 rotatingshafts, 12 handwheels, 13 spools, 14 inner spools, 15 Decompression valvess, 16 latch plates, 17 flanges, 18 seal grooves of 1 valve cylinder, 2 back-fire relief pipes, 3 valve plates, 4 ports, 5 valve bodies, 6 sieve plate holes
Embodiment
Illustrate in conjunction with Fig. 1 embodiment:
Safety valve comprises valve body 5, and the end of valve body has flange 17 and cooperates with pressurized container, has a plurality of ports 4 on the valve plate 3 on the top, valve cylinder 1 is set on the port 4 is threaded with port.What contact with port in the valve cylinder 1 is spool 13, and top is that sieve plate hole 6 is that internal thread is connected with valve cylinder, and 13 of sieve plate hole 6 and spools are pressure spring 10.One inner spool 14 is set in valve body 5, inner spool 14 is connected with rotatingshaft 8 by transverse axis 9, the outer umbrella gear 7 of rotatingshaft 8 and valve body is connected, and umbrella gear 7 is by rotatingshaft 11 connection handwheels 12, and latch plate 16 is connected in 14 of rotatingshaft 8 and inner spools to compress inner spool.
Valve body 5 is installed on the pressurized container by flange 17, as requested, suppress by the sieve plate hole 6 on the valve cylinder 1 and to compress pressure spring 10 setting pressures, the sieve plate hole is pressure spring 6 fixedly, when the pressurized container internal pressure reached limit value, too much gas was got rid of in the spool take-off in the safety valve valve cylinder, to reduce container internal pressure, guarantee production safety.Under the normal condition, inner spool 14 not with any port sealing, when a certain valve cylinder need be suppressed, driving inner spools 14 by handwheel 12 Rotatable umbrella gears 7 turns on this valve cylinder corresponding port and cooperates, because of pressurized container inside has pressure, communicate in pressurized container and the valve body, on inner spool 14, have pressure difference, this pressure closely cooperates inner spool and port, plays seal action.After this valve cylinder is installed, forward inner spool to other positions again and get final product.Therefore, valve cylinder can be dismantled easily in working environment, install, and does not influence production.The quantity of port is according to the different discharge amount settings of pressurized container.
