Abstract

The utility model discloses a three-way universal valve with an inner screw loose joint and an outer screw loose joint, comprising a valve body, a spherical valve core, a handle, a spring, a sealing pad, a sealing ring, screws and loose joints, wherein all the handle, the spring and the sealing pad adopt the prior art. The spherical valve core is fixedly connected with the handle and is internally provided with a T-shaped through hole which passes through the central point of the valve core, and is provided three ports in total, wherein the three ports are respectively communicated with a pipeline; a wear self-complementary device is arranged at each port in the valve body; a positioning pin is arranged at the bottom of the valve body; the spring is additionally arranged behind the sealing pad to be matched with a pin hole in the bottom of the spherical valve core so as to enable the spherical valve core to keep the vertical center; threads are arranged at the outer circle and the inner circle in a three-way outer joint of the valve body, and the screws press the loose joints to be butted with the ports of the valve body. In the three-way universal valve, the inner screw and the outer screw of a joint of the inner valve body can be convenient for butted installation of the pipeline, so that the installing cost and the working hour are saved.

Description

The universal valve of threeway with the loose joint of inside and outside silk

Technical field

The utility model relates to a kind of valve, relates in particular to the universal valve of threeway with the loose joint of inside and outside silk.

Background technique

Valve before the utility model is realized generally can only be controlled two adjacent pipelines, and when needs are controlled three pipelines simultaneously, can only use two valves to control between the valve group simultaneously; And the universal valve of existing threeway is connected with pipeline, driving spherical valve core by rotatable handle during use rotates, and the port that makes the T type through hole by the spherical valve core central point respectively with the pipe end screw meticulous cooperate to install get final product, but existing pipe ends cylindrical often must process the interface that screw just can be installed into the universal valve of threeway, and the pipe ends of selling on the market does not mostly process screw, needs to install in addition inside and outside silk loose joint device.

Summary of the invention

The utility model is to solve the defective that exists in the prior art, and a kind of universal valve of threeway with the loose joint of inside and outside silk is provided, thereby has overcome the deficiency in the above-mentioned technology.

The universal valve of threeway with the loose joint of inside and outside silk described in the utility model comprises: handle, valve body, spherical valve core, sealing gasket, and spring, seal ring, spiral shell are buckled, loose joint, handle wherein, spring and sealing gasket all adopt prior art.Described spherical valve core is fixedlyed connected with handle, have in the spherical valve core one by center spool point T type through hole totally three ports communicate with pipeline respectively; Wearing and tearing are installed from mending device in each port in valve body; Described valve body, the bottom is provided with positioning dowel, adds shock mount and cooperate with spherical valve core bottom pin-and-hole behind sealing gasket, makes spherical valve core, keeps vertical centre; The threeway external tapping inside and outside circle of described valve body all is processed with screw thread, and spiral shell is withheld tight loose joint and docked with valve body port, and seal ring plays the leakproof effect; Threadless for pipe joint, need connect by silk loose joint device inside and outside the valve interface, with the component of simplifying installation process and needing.

The universal valve of threeway with the loose joint of inside and outside silk described in the utility model, the inside and outside silk of valve body interface can make things convenient for the butt joint of pipeline to install, and has reduced installation cost, and installation work-hour.

Embodiment

Below in conjunction with description of drawings the utility model is further elaborated.

The universal valve of threeway with the loose joint of inside and outside silk described in the utility model, comprise: handle 1, valve body (2,8,10), spherical valve core 3, sealing gasket 4, spring 5, seal ring 11, spiral shell buckle 12, loose joint 13, and wherein handle 1, and spring 5 and sealing gasket 4 all adopt prior art.Described spherical valve core 3 is fixedlyed connected with handle 1, have in the spherical valve core 3 one by center spool point T type through hole totally three ports communicate with pipeline respectively; Wearing and tearing are installed from mending device in each port in valve body; Described valve body, the bottom is provided with positioning dowel, adds shock mount 5 and cooperate with spherical valve core 3 bottom pin-and-holes behind sealing gasket 4, makes spherical valve core 3, keeps vertical centre; The threeway external tapping inside and outside circle of described valve body all is processed with screw thread, and spiral shell button 12 compresses loose joint 13 and docks with valve body port, and seal ring 11 plays the leakproof effect.

Fig. 1～Fig. 2～Fig. 3 has shown priority scheme of the present utility model, each port is equipped with the wearing and tearing that add shock mount 5 behind sealing gasket 4 and mends device certainly in valve body 2, then spherical valve core 3 is pressed in the valve body 2, spherical valve core 3 is contacted fully with sealing gasket 4, and the pin-and-hole 6 of spherical valve core 3 bottoms is cooperated with the positioning dowel 7 of valve body 2 bottoms, make spherical valve core 3 keep vertical centre, subsequently handle 1 lower end is inserted valve body 2 backs and fixedly connected with the spherical valve core 3 in placing valve body; With bolt valve body 2, valve body 8 closely are connected with valve body 10, the spiral shell button 12 of at last mounted valve being screwed on compresses seal ring 11, loose joint 13 is docked with valve body port, is connected with pipeline again; Pipe joint is threadless, need to connect by silk loose joint 13 devices inside and outside the valve interface, only need to drive spherical valve core during use and rotate, and make the port of the T type through hole 9 by spherical valve core 3 central points corresponding with the mouth of pipe respectively, can reach application target by rotatable handle.
