Abstract
The invention relates to a straight-through type mute stop valve which comprises a valve body and an unsealing piece. The valve body is composed of a first connecting piece and a second connecting piece. A water inlet channel is arranged in the first connecting piece, a water outlet channel is arranged in the second connecting piece, and a second baffle is arranged on one side of the water outlet channel. The unsealing piece comprises a disc, a first connecting rod and a second connecting rod, and a spring is arranged outside the second connecting rod. Backflow liquid can be stopped and sealed fast and flexibly, the mute sealing performance is good, and the fluid is not prone to leaking.
Description
Technical field
Safety check is also known as one-way valve or check valve, and its effect prevents the medium in pipeline from flowing backwards, and the bottom valve that pump sump closes also belongs to safety check class.Safety check is that a kind of open-shut device is opened voluntarily or closes by media flow and strength, the valve flow backwards to prevent medium, belongs to self-acting valve class, is mainly used on the pipeline of medium one-way flow, only allows medium to flow to a direction, to try to avert accidents.
Safety check kind of the prior art is a lot, but the non-return transmission efficiency of safety check and quiet sealing one are safety check study hotspot and difficult point.
Background technique
The present invention relates to a kind of valve, specifically the quiet stop valve of a kind of straight-through type.
Summary of the invention
The object of the invention is the defect for prior art, provide a kind of straight-through type quiet stop valve, only can seal withdrawing fluid rapidly and sensitively, and quiet good airproof performance, fluid is easy to leak not.
The present invention is achieved by the following technical solutions:
A kind of straight-through type high leak tightness safety check, comprise valve body and unpacking part, described valve body is made up of the first link and the second link, intake tunnel is provided with in described first link, described intake tunnel side is provided with the first baffle plate, described first baffle plate both sides are connected with the first link inwall, and described first baffle plate is provided with protruding ring and the first through hole, and described first through hole and intake tunnel are coaxially arranged;
Described first link one end is through the second link, and be connected with the second link, cavity is provided with between described first link and the second link, exhalant canal is provided with in described second link, described exhalant canal side is provided with second baffle, described second baffle both sides are connected with the second link inwall, and described second baffle is provided with the second through hole and some slotted eyes, and described second through hole and exhalant canal are coaxially arranged;
Described unpacking part is arranged in cavity, described unpacking part comprises disk body, head rod and the second connecting rod, described head rod is connected with disk body both sides respectively with the second connecting rod, described head rod and the first through hole with the use of, described second connecting rod and the second through hole with the use of, spring is provided with outside described second connecting rod, described spring one end is connected with disk body, the other end is connected with second baffle, groove is provided with outside described disk body, be provided with pad in described groove, described pad is corresponding with the protruding ring position of the first baffle plate to be arranged.
Above-mentioned a kind of straight-through type high leak tightness safety check, wherein, described some slotted eyes be three layers circular evenly distributed.
Beneficial effect of the present invention is:
Working method of the present invention is: the present invention be arranged on fluid circuit, when fluid passes into intake tunnel, hydrodynamic pressure makes head rod be ejected by the first through hole, spring-compressed, and fluid can flow through the first through hole, cavity, slotted eye and exhalant canal from intake tunnel and flow out; When hydrodynamic pressure stops promoting, spring reset, drives the second connecting rod resilience, makes head rod block through hole as in the first through hole; Anti-fluid backflow.
The present invention blocks through hole with connecting rod, and with the protruding ring fitted seal of pad and the first baffle plate, makes the present invention only can seal withdrawing fluid rapidly and sensitively, and quiet good airproof performance, fluid is easy to leak not.
