Abstract

The utility model discloses an accessory type unidirectional throttle valve. A small hole (3) is arranged in the middle of a valve plate (2), a plurality of big holes (4) are arranged on the circumference of the valve plate (2), the valve plate (2) is installed in a valve body (1) through a retaining ring (5) and formed into a unidirectional throttle valve, when in use, liquid flows along a positive direction, the valve plate (2) is pushed to the side of the retaining ring (5), the liquid flows through all holes, the liquid flows along a unidirectional direction without throttling, the liquid flows along a reverse direction, the valve plate (2) is pushed to the valve body (1), the valve plate (2) is attached with the plane of the valve (1), a plurality of big holes (4) which are on the circumference of the valve plate (2) are blocked completely, and the liquid is throttled and only flows through the small hole (3) in the middle. The utility model has simple structure and low cost, the valve plate as an accessory is installed in executive components, other relative steps can be saved, and the reliability is good.

Description

Annex type one-way throttle valve

Technical field

The utility model relates to hydraulic pressure and Pneumatic unidirectional throttling arrangement, is specifically related to a kind of annex type one-way throttle valve.

Background technique

At present, at hydraulic pressure and pneumatic, especially general one-way throttle valve is provided with check configuration and throttle structure in order to finish the one-way throttle function in hydraulic pressure, so complex structure, volume are bigger, and cost increases, and reliability reduces.Such as, the one-way valve of one-way function has valve and spring, and the throttling function throttle valve is provided with restriction and controlling device, and each functional features all might have side effects and reduce product reliability.And some machinery is less demanding but require good reliability to throttling function, and as bearing the oil cylinder that weight requires to vertically being placed with, it is when descending, and is less demanding to throttling function, but can not go wrong, and requires the throttling good reliability.

Summary of the invention

The purpose of this utility model is: a kind of annex type one-way throttle valve is provided, and this valve is installed in realizes unidirectional and throttling function in the executive component, single, with low cost between structure, the reliability height.

Technical solution of the present utility model is: this valve is made up of valve body, valve block, back-up ring, and aperture is established in the centre of valve block, and some macropores are arranged on the circumference of valve block, and valve block is installed in by back-up ring and constitutes one-way throttle valve in the valve body.

In the annex type one-way throttle valve of the present utility model, a wherein end face of valve block is promptly towards the end face indent of back-up ring.

In the annex type one-way throttle valve of the present utility model, valve block can be an arbitrary shape, and its hole can be an arbitrary shape, and the big smallest number in hole is appraised and decided according to calculating or experiment according to actual demand.

In the annex type one-way throttle valve of the present utility model, back-up ring can be the gauge hole back-up ring, also can threaded collar or arbitrary shape back-up ring.

In the annex type one-way throttle valve of the present utility model, valve body can be pipeline, joint as matrix.

During use, the fluid forward flow, valve block is pushed to back-up ring one side, and fluid is moving by whole orifice flows, and the fluid one-way flow does not have throttling; Reverse fluid flow, valve block is pushed to valve body, and fit in valve block and valve body plane, and some macropores are blocked on the valve block circumference, and fluid can only pass through by middle orifice restriction.

The utility model is simple in structure, and is with low cost, and valve block is installed in as annex and saves other relevant link, good reliability in the executive component.
