Abstract

The utility model relates to a three-way telescopic join valve, belonging to mechanical pipeline jointing valves. The structure of the three-way telescopic join valve is that the three sides of a cross valve body are provided with three external pipe joints; the other side is provided with a press cap; the middle of the press cap is provided with a valve rod; the top of the valve rod is connected with a handle; the lower end of the valve rod is connected with a T-shaped valve rod head; a rubber ring corresponding to the valve rod head is arranged in the valve body; the inner side of the valve body is compactly pressed with the rubber ring; a rubber ring nylon pad is arranged in each of the external pipe joints; each of the external pipe joints is connected with the valve body by screw threads. The utility model has the advantages of simple structure, multiple use with one valve, pressing connection of external pipes, convenient installation and convenient use.

Description

Three-way telescopic join valve

The utility model belongs to mechanical pipeline and connects valve.

The valve of installing at mechanical pipeline is all the single channel valve, an input end, an output terminal at present, ball valve or stop valve are equipped with in the centre, though the pipeline that has is equipped with three-way union, not having has valve closing to open function, this kind valve simple structure, easy to install, but function singleness can't be used at some special occasions, has only the adjunction line branching, and joint is too many, be not easy to use and keep in repair, particularly sealing is poor, and evaporating, emitting, dripping or leaking of liquid or gas is inevitable.

For solving the single deficiency of above valve function, the purpose of this utility model provides a kind of threeway the flexible valve that connects, adopt three branch lines, the centre has valving, and each branch road connects non-threaded being fastenedly connected of employing, have very big stretchability, effectively solved the problem of multi-functional valve and the inconvenience of connection method, saved other annex of pipeline widely.

Structural design of the present utility model is one " ten " font valve body (as shown in Figure 1) in the middle of being achieved in that the flexible connection of threeway valve, make by Cast Steel, the valve pressure cap is housed above valve body, in the pressure cap intermediate vertical valve rod is housed downwards, the top of valve rod is a handwheel, the lower end connects stem head, with valve rod by bolton, top at pressure cap is with plug wire, it below the plug wire packing ring, top for rubber cushion, be buckled with nut above the rubber cushion, valve rod passes in the circular hole of nut, plug wire and rubber cushion centre, and closely cooperates with valve rod; Stem head is " T " font, the relative cushion rubber that should be with stem head below in valve body, closely cooperate with " T " font stem head after the pressing, it below the stem head externally connected pipe joint, around the top of externally connected pipe and the valve body joint is rubber cushion, the rubber cushion outside is with nylon pad, nylon pad outermost tube joint, with valve body for being threaded, following has the outer trim ring, can rotate with hand, in the valve body left and right sides pair outer tube joint is arranged respectively, can externally connect externally connected pipe in the pipe joint, its outer ring, termination is added with cushion rubber and nylon pad respectively, add pipe joint, be connected identical with valve body with the valve body lower end pipe joint.

Its working principle: when the handwheel rotation, valve rod is raised, below stem head mentioned simultaneously by valve rod, following externally connected pipe is opened, simultaneously with about two externally connected pipe communicate, the handwheel counter-rotating, valve rod moves down, and makes stem head and lower linking tube because nylon pad closely cooperates and is closed, and two externally connected pipe are cut off about the while, if following pipe is made supplying tube, just can connect or close the both sides externally connected pipe by the lifting of valve rod.

The utility model has following advantage compared with the prior art: simple in structure, multi-purpose valve, externally connected pipe adopt pressure pad to connect, scalable easy to install, can in various mechanical pipelines, use.

Detailed structure of the present utility model is provided by following examples and accompanying drawing.

Fig. 1 connects the valve arrangement schematic diagram for threeway is flexible.

Its structure is known by Fig. 1, (1) is valve body, be " ten " font, pressure cap (2) is equipped with on its top, plug wire (3) is equipped with on pressure cap (2) top, below the plug wire (3) is packing ring (8), be rubber cushion (6) above, above the rubber cushion (6) is nut (5), valve rod (7) is equipped with in the centre, handwheel (4) is equipped with on valve rod (7) top, the lower end is connected with stem head (11), fastening with valve rod (7) with bolt (10), below the stem head (11) is nylon pad (16), closely cooperate with " T " font stem head (11), below the nylon pad (16) is externally connected pipe (12), be added with rubber cushion (15) around its pipe end, the outside is with nylon pad (17), be added with pipe joint (18) above the nylon pad, with being threaded, pipe joint (13) outer is bigger between pipe joint (18) and the valve body (1), can rotate by hand, valve body (1) both sides are added with externally connected pipe (12) (19) respectively, and cushion rubber (14) and nylon pad (17) are housed in the externally connected pipe both sides, and it is identical with following pipe joint structure that the outside is added with pipe joint (13) (21).Stem head (1) is mentioned, and is the threeway state, and stem head descends, and turn-offs threeway.
