Abstract
The utility model discloses a pressure sealing angle type lifting check valve with double anti-rotation structures comprising a cylindrical pin and an additional key. A valve clack is connected with a valve body. A lining is connected with the valve clack through the key. The cylindrical pin is connected with the lining and the valve body. A valve deck is connected with the lining. A halving ring is connected with the valve deck and the cylindrical pin. A pressure equalizing ring is connected with the valve deck and sealed through a pressure sealing ring. A quartered ring is connected with the pressure equalizing ring. A supporting plate is connected with the valve body and the quartered ring and screwed down through a bolt. A nut is connected with the bolt. A lifting bolt is connected with the supporting plate. According to the pressure sealing angle type lifting check valve, as the novel anti-rotation structure is arranged, abrasion to the sealing face from the valve clack in the moving process is reduced, the service life of the valve is prolonged, loss of materials is reduced, the machining difficulty is lowered, the cost is reduced, and the structure is stable and durable.
Description
Technical field
The utility model relates to field of mechanical technique, is specially a kind of straight pin and adds the two rotation prevention structure wiper seal angie type lift check valves of key.
Background technique
At present, the wiper seal angie type lift check valve of main flow on market, or usual pressure sealing Lift check valve, normally common valve cover strip piston cylinder operator, the neck extending by flap moves in piston, realize valve with MEDIA FLOW to automatic on-off.But, there is following shortcoming in this kind of structure: 1,, in the time that medium produces turbulent flow, the relative valve seat of flap can rotate, and has accelerated the wearing and tearing of sealing surface, reduces the working life of valve; 2, because piston and valve gap are one, in forging process, wasted material; 3,, in course of working, the design of valve gap fixture and the control ratio of machining accuracy are more difficult.
Model utility content
The purpose of this utility model is in order to provide a kind of straight pin to add the two rotation prevention structure wiper seal angie type lift check valves of key, to solve the problem proposing in above-mentioned background technology.
In order to achieve the above object, the utility model is realized by the following technical solutions:
A kind of straight pin adds the two rotation prevention structure wiper seal angie type lift check valves of key, comprise valve body, flap, lining, key, straight pin, valve gap, two points of rings, piezometer ring, pressure sealing ring, four points of rings, support plate, double-screw bolt, nut, lifting bolt, described flap is connected with valve body, described lining is connected with flap by key, described straight pin is connected with lining, and be connected with valve body, described valve gap is connected with lining, described two points of rings are connected with valve gap, and be connected with straight pin, described piezometer ring is connected with valve gap, and seal with pressure sealing ring, described four points of rings are connected with piezometer ring, described dunnage is connected with valve body, and be connected with four points of rings, and with screwing up stud, described nut and Stud connection, described lifting bolt is connected with dunnage.
As preferably, described flap is connected by Full dog point socket set with valve body.
As preferably, described key is between flap and lining.
As preferably, described straight pin has two, between valve body and lining.
As preferably, described valve gap is connected by Full dog point socket set with lining.
The utility model wiper seal angie type lift check valve provides a kind of Novel anti-rotation structure, between flap and lining, increase a key, flap is not rotated with respect to lining, between lining and valve body, with 2 straight pins, restriction lining and valve body produce relative rotation, finally make flap can not rotate, reduce flap wearing and tearing to sealing surface in movement process thereby reach, improve the working life of valve, and reduced the loss of material, reduce difficulty of processing and cost, structural stability and durable.
