Abstract
Provided is a plug-in type variable diameter pipe joint which is mainly applied to the connection of PE pipes of different diameters in a water supply pipeline of a drip irrigation system. The pipe joint includes a tubular joint body and is characterized in that the excircles of the two ends of the tubular joint body are respectively provided with an inserting cover, a section of tapping thread is arranged in the inner hole of each inserting cover, and the end of each inserting cover is provided with a pair of elastic clips. A pipe connected to the inserting covers is inserted into the tubular joint body, and then the elastic clips on the inserting covers are clamped in the notch of the joint body to enable the plastic pipe, the inserting covers and the joint body to be connected into one body.
Description
Technical field
The utility model relates to a kind of drip irrigation system and uses plastic water pipe joint.Belong to the pipeline connection technology field.
Background technique
Drip irrigation technique is being widelyd popularize at present; The water transport pipeline ways of connecting is of all kinds in the drip irrigation system; Wherein the quick replacable type reducer union is used morely, but present most of quick change reducer union is that to form the number of spare parts of quick change reducer union more by individual common problem, causes cost higher.For this reason, researched and developed a kind of number of spare parts few, change reduction nipple easily.
Summary of the invention
The purpose of the utility model is to provide a kind of drip irrigation system to use the plug-in type reduction nipple; This reducer union can connect and open the PE plastic tube of all size that uses in the drip irrigation system easily; This reducer union is a quick release coupling, and the assembly of joint is less, and linkage function is reliable; Cost is low, is fit to promote the use of.
The purpose of the utility model is realized by following proposal: a kind of plug-in type reduction nipple; Comprise a tubular configured joint body; Respectively there is one to insert lid on the cylindrical of said reducer pipe straight coupling body two ends; Inserting to cover has one section tapping thread (screw thread has cutting edge, and is similar with the screw thread of screw die) in the endoporus, there is a pair of elasticity card the termination of inserting lid.On the cylindrical at fittings body two ends, groove is arranged, this groove is used for adorning seal ring.Insert connected plastic tube in slotting the lid, the slotting lid of rotation is owing to having Thread Forming TF in the slotting lid, so when slotting lid rotates, just link together connected pipe tap out and with slotting lid.With insert the pipe insertion tube straight coupling body that lid links together, insert in the draw-in groove that the elasticity card that covers just is stuck in fittings body and make plastic pipe, insert lid and fittings body is connected in one, reach the purpose that connects plastic tube.Insert the effect that connects pipe of building.Seal ring is leaned in the sealing of water.Pushing the elasticity card aside can pull up and insert lid and open joint.Insert the outer surface of lid and make anti-skid design, manually actuated during installation.The material of this plug-in type reduction nipple is harder plastics such as ABS, also can be metal.
The beneficial effect of the utility model is, it simple in structure, and the part of integral connector is few, and is easy to install, and linkage function is reliable, has reduced the cost of pipe joint effectively.This pipe joint also can be used for other plastic duct systems.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the tectonic maps of the utility model.
Fig. 2 is a sectional drawing of inserting lid.
1. fittings bodies among the figure are 2. inserted lid, 3. rubber seal, 4. plastic tube.
Embodiment
In the embodiment shown in fig. 1; Rubber seal (3) is housed in the groove of fittings body (1); Connected reducing PE plastic tube is inserted in the hole of lid (2) and impose certain axial force; Rotate to insert lid (2) and the tapping thread of inserting lid is cut get in the plastic tube (4), inserted lid (2) neutralization and insert lid (2) and link together securely along with the rotary plastic pipe (4) of inserting lid (2) can be drawn into automatically.Insert in the draw-in groove that the elasticity card of then inserting on the fittings body (1) on the lid (2) just is stuck in fittings body (1) and make fittings body (1), insert lid (2) and link together closely having the plastic tube (4) of inserting lid (2) then, reach the purpose of connection plastic tube with plastic tube (4).Rubber seal (3) plays sealing water.Fig. 2 is a sectional drawing of inserting lid (2), and it is anti-skid design that lid (2) outer surface part is inserted in its expression, convenient manual operations.When needs are opened joint, can push the elasticity card of inserting on the lid (2) aside withdraws from plastic tube (4) and gets final product.
Claims (1)
1. a plug-in type reduction nipple comprises a tubular configured joint body, it is characterized in that: respectively have one to insert lid on the cylindrical at said tubular configured joint body two ends, inserting to cover has one section tapping thread in the endoporus, and there is a pair of elasticity card the termination of inserting lid.
