The utility model belongs to the technical field of a valve, and relates to a drainage valve, in particular to a drainage valve with an improved structure. The drainage valve solves the problem that designs in the prior art are not reasonable. The drainage valve comprises a three-way body and a valve core assembly, wherein the three-way body comprises a by-pass end and two straight-pass ends, the valve core assembly comprises a ball valve and a valve rod which is connected with the ball valve and can control motions of the ball valve, and a control handle is connected with the valve rod. The drainage valve is characterized in that a connector is connected with the by-pass end, the ball valve is arranged between the connector and the by-pass end, and a first sealing ring is respectively arranged between the connector and the ball valve, and the by-pass end and the ball valve. Compared with the prior art, the drainage valve has the advantages of being reasonable in design, simple in structure, good in sealing property, and simple and convenient to install or dismantle.
Description
Technical field
The utility model belongs to valve technology field, relates to blowdown valve, relates in particular to a kind of structure improved blowdown valve.
Background technique
Blowdown valve can play the blowdown effect; Blowdown valve has simple in structure, good airproof performance; And volume is little, in light weight, material consumption is few, installation dimension is little, and particularly driving moment is little, and is easy and simple to handle; Be prone to realize advantages such as fast opening and closing, be widely used in the various pipeline drainages; In the prior art, blowdown valve generally comprises tee union, in tee union, is provided with mangetic core assembly, and the ball valve in the mangetic core assembly directly contacts the inwall of tee union, and externally connected pipe directly is connected on the bypass side pipe.This scheme can satisfy usage requirement to a certain extent, but after using repeatedly, has water leakage phenomenon, difficult installation.
In order to solve the problem that existing technology exists, people have carried out long-term exploration, have proposed various solutions.For example; The Chinese patent document discloses a kind of three-way valve [application number: 02290447.6], comprises valve body and spool, it is characterized in that: valve body is a T font through hole; Spool is the middle spheroid that has T font through hole, and the T font through hole of spool is consistent with the T font through hole of valve body.
Such scheme has improved existing technology to a certain extent, but after long-time the use, bypass-side is leaked easily, and sealing is poor, has shortened working life, and when installing or dismantling, operation is more loaded down with trivial details, and is not easy to assemble, reduced manufacturing efficiency virtually.
Summary of the invention
The purpose of the utility model is to the problems referred to above, provides a kind of reasonable in design, simple in structure, and good airproof performance is installed or easy removal long service life, the structure improved blowdown valve that can also enhance productivity.
For achieving the above object, the utility model has adopted following technical proposal: comprise threeway body and mangetic core assembly, the threeway body comprises bypass ends and two straight-through ends; Mangetic core assembly comprises ball valve and links to each other with ball valve and can control the movable valve rod of ball valve; On valve rod, be connected with Joystick, it is characterized in that, be connected with joint on the described bypass ends; Ball valve is respectively equipped with first seal ring between described joint and ball valve, bypass ends and the ball valve between joint and bypass ends.Owing to be provided with first seal ring, good airproof performance is not prone to water leakage phenomenon, has prolonged working life.
In above-mentioned structure improved blowdown valve, be fixed with bypass tube through the mechanism that removably connects on the described bypass ends, between bypass tube and bypass ends, be provided with second seal ring.Further strengthen sealing.
In above-mentioned structure improved blowdown valve, the described mechanism that removably connects comprises locking cap.Attaching/detaching is simple and convenient.
In above-mentioned structure improved blowdown valve, described threeway body is T-shaped.
Compared with prior art, the advantage of this structure improved blowdown valve is: 1, reasonable in design, simple in structure.2, owing to be provided with first seal ring, good airproof performance is not prone to water leakage phenomenon, has prolonged working life.3, owing to be provided with detachable mechanism, installation is torn open/unloads simple and convenient.
