Abstract

The utility model discloses a cross joint which consists of an inner wire plugging reducing sleeve and a crossed hollow male thread connecting short pipe; the inner chamber screw thread of a connector of the inner wire plugging reducing sleeve is adapted and connected with screw threads of four joints of the crossed hollow male thread connecting short pipe; and tapered sealed rubber rings adapted with the shape of the screw threads are arranged on the four joints of the crossed hollow male thread connecting short pipe. The cross joint adopts a screw tapping principle in design in order to form tapping action between the plugging reducing sleeve and the crossed hollow male thread connecting short pipe under the manual action; a tapered snap ring clamps the pipe wall to realize sealed and reliable connection through the sealed rubber ring; experiments show that the cross joint has the characteristics of scientific design, strong practicability, and the like.

Description

A kind of four-way
Technical field
The utility model belongs to a kind of pipe fitting technology, particularly a kind of four-way of piping erection accessory.
Background technique
PE tubing extensively is used in the drip irrigation system in agricultural with its good water-fast hammer pressure, power water-based, pliability and weldable, and the PE four-way is the important accessory of this system, rises to connect and shunting action.Along with drip irrigation technique constantly develops, people install accessory to this class droping irrigating pipe and require more and more higher.The problem that occurs is that droping irrigating pipe accessory and tubing do not match at present, adopt the hot melt way mostly, the technical requirements height, and exist the operating technology difficulty big, make troubles for the installation of droping irrigating pipe, directly influenced the speed that droping irrigating pipe is installed, the whole erection expense is higher, need develop a kind of PE four-way accessory that droping irrigating pipe is installed that is exclusively used in for this reason.
Summary of the invention
The purpose of this utility model provides that a kind of join strength height, ageing-resistant, corrosion resistance are strong, simple installation, workable, agricultural droping irrigating pipe accessory four-way that sealing is good.
For achieving the above object, solution of the present utility model is: a kind of four-way, being connected short tube by internal thread socket joint reduction center with a cross hollow external screw thread forms, the thread in inner cavity of described internal thread socket joint reduction center interface is connected the suitable connection of screw thread of four joints of short tube with a cross hollow external screw thread, described cross hollow external screw thread connects four joints of short tube and is provided with the taper card sealing rubber ring suitable with its screw thread form.
The utility model has adopted spiral self tapping principle in design, socket joint reduction center and cross hollow external screw thread are connected between the short tube under manual action, form the self tapping effect, the taper snap ring is blocked tube wall, by sealing rubber ring, realized that sealing, fixing connect.Through test, the utlity model has design science, can be practical etc. characteristics.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.
Embodiment
As shown in Figure 1, a kind of four-way described in the utility model, being connected short tube 3 by internal thread socket joint reduction center 1 with a cross hollow external screw thread forms, the thread in inner cavity of described internal thread socket joint reduction center 1 interface is connected the suitable connection of screw thread of 3 four joints of short tube with a cross hollow external screw thread, described cross hollow external screw thread connects 3 four joints of short tube and is provided with the taper card sealing rubber ring 2 suitable with its screw thread form.Described taper card sealing rubber ring 2 is a helical, and it is ductile.A described internal thread socket joint reduction center 1 is enclosed within on the tube wall of PE pipe, internal thread socket joint reduction center 1 appearance is designed to polygonal, be convenient to manually screw this internal thread socket joint reduction center 1, then taper card sealing rubber ring 2 is enclosed within the tube head of PE pipe, the outer wall of taper card sealing rubber ring 2 has the half-open osculum in four roads to be divided into 4 half, can freely stretch in the time of on being nested in the PE pipe, there are four sections tongues at the outer wall middle part of taper card sealing rubber ring 2, its effect is to be stuck in internal thread socket joint reduction center 1 inwall, the PE tube head that fixedly is inserted in, making it be connected cross hollow external screw thread connects on the short tube 3, the port that cross hollow external screw thread connects short tube 3 connects with four taper card sealing rubber rings 2, taper card sealing rubber ring 2 fixing PE tube heads are connected short tube 3 and form the self tapping effect with cross hollow external screw thread, the PE tube head is tightly withstood on the taper card sealing rubber ring 2, this taper card sealing rubber ring 2 has very strong rebound elasticity, follow the power of self tapping effect, can stretch automatically, three PE pipes of other three ends and other with taper card sealing rubber ring 2 snap rings are connected equally, screw the polygonal of socket joint reduction center 1 outside, make it closely be connected cross hollow external screw thread and connect on the short tube 3, under manual action, just can realize finishing fast connection the PE pipe.
Above-mentioned four-way has changed the connection way that adopts hot melt in the past, and only need select for use the utility model just can reach purpose of connecting, technical difficulty reduces greatly, adopt by hand and just can carry out good connection, simple installation, workable, sealing is good, effectively solved the common run, drip, leak phenomenon of such pipe fitting, cheap, can effectively reduce the construction work cost, the utlity model has the join strength height, ageing-resistant, corrosion resistance is strong, can repeatedly dismantle use.
