Abstract
The utility model discloses a flexible seal check valve which comprises a valve body, wherein an inlet and an outlet are formed in the valve body; the inlet and the outlet are communicated with each other and are provided with channels in which a medium flows; the inner wall, which is close to the inlet, of the valve body is connected with a rocker in a rotatable manner; the lower end of the rocker is connected with a valve clack; a valve seat matched with the valve clack to realize sealing is arranged at the inlet; a valve cover is arranged above the valve body; and a pressure release valve is arranged on the valve cover. The flexible seal check valve is reasonable in structural design; the pressure release valve is arranged on the valve cover and is hardly blocked because the pressure release valve is far away from the inlet and the outlet, and the flowing of the medium in the check valve cannot be affected; therefore, the pressure in the valve body can be effectively reduced and the arrangement of other pipe fittings is not affected.
Description
Technical field
The utility model belongs to valve technology field, relates to a kind of soft-sealing check valve.
Background technique
Safety check claims again one-way valve or check valve, and its effect is to prevent that the medium in pipeline from flowing backwards.Open-shut device is opened voluntarily or closes by media flow and strength, to prevent that valve that medium flows backwards is on safety check.Safety check 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.Common safety check is not with Decompression valves, when safety check internal pressure is too high, easily meets accident.
Model utility content
The purpose of this utility model is to provide a kind of soft-sealing check valve, has solved common safety check in prior art and has used unsafe technical problem.
The technological scheme that the utility model adopts is: this soft-sealing check valve, comprise valve body, on valve body, be equipped with import, outlet, import is communicated with and is provided with the passage of confession medium circulation with outlet, on the inwall of described valve body near inlet, be rotationally connected rocking bar, the lower end of rocking bar is connected with flap, and inlet is provided with the valve seat with flap fitted seal, described valve body top is equipped with valve gap, is equipped with Decompression valves on valve gap.
Optimization as technique scheme: rocking bar lower end is equipped with mounting hole, flap is provided with and coordinates the connecting rod of installing with mounting hole, the inner segment of connecting rod is partly provided with the arc surface of the evagination adapting with mounting hole, and outer section of part of connecting rod is equipped with nut.
Further optimization as technique scheme: nut is provided with cotter pin, is equipped with plain cushion between nut and rocking bar.
Further optimization again as technique scheme: valve body inner bolt is connected with Y-piece, the right and left of Y-piece is provided with supporting bar, the lower end of supporting bar is equipped with for connecting the perforation of rocking bar, Y-piece is connected by bearing pin with rocking bar, and the top of Y-piece is equipped with for being fixed in the fixed hole in valve body.
Further optimization as technique scheme: valve body and valve cover chamber are equipped with spiral wound gasket.Valve body is connected with valve gap bolt.Valve gap is provided with suspension ring.
The beneficial effects of the utility model are: the utility model reasonable in design, on valve gap, be equipped with Decompression valves, and Decompression valves is far away apart from import and outlet, be difficult for blocked, do not affect medium flowing in safety check, can effectively reduce valve body internal pressure, do not affect other pipe fittings and arrange.Sealing is high, and the maintenance of valve seat is changed convenient.Valve gap can folding, is convenient to inner maintenance, is designed with suspension ring, convenient lifting.
