Abstract
The utility model disclose a kind of can the plate valve of pressure release, comprise valve seat, flashboard and valve rod, described valve seat comprises the first valve seat and the second valve seat, described flashboard and closely cooperating between described first valve seat and described second valve seat, described valve rod one end connects described flashboard, the other end connects turn switch, it is characterized in that: in described flashboard, be provided with cavity and through hole, pressure relief component is provided with in described cavity, described pressure relief component can be stretched out or regain from described through hole, and described valve rod is connected with described pressure relief component by transmission part.The plate valve of the technical program can the technique effect of real pressure release, thus staff can complete valve opening and closing operation easily, and for alleviating the extruding to valve plate of liquid in opening and closing process, preventing valve plate torsional deformation to have good effect.
Description
Technical field
The utility model relates to mechanical manufacturing field, especially relate to a kind of can the plate valve of pressure release.
Background technique
Plate valve be widely used in now product oil pipeline, with in other pipelines such as pipeline of suspended particulate medium.The high leak tightness that plate valve itself has, operation convenience, advantages of simple structure and simple are that it obtains the key of constantly approval.But, when control valve is opened, because the liquid that flows through from upstream line can because the valve plate pressure of opening the difference of height and the liquid that cause valve plate to be subject to be also different, namely the fluid pressure on valve plate top is greater than the fluid pressure of bottom, thus easily causes valve plate to be distorted distortion; And in order to valve plate being promoted or declining, need to use certain power operating switch, now valve plate receives the pressure extrusion of left and right valve seat, although have good sealing, but need more strength when opening simultaneously or close valve plate, cause the increase of working strength.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the purpose of this utility model be propose a kind of can the plate valve of pressure release.
The purpose of this utility model will be achieved by the following technical programs: a kind of can the plate valve of pressure release, comprise valve seat, flashboard and valve rod, described valve seat comprises the first valve seat and the second valve seat, described flashboard and closely cooperating between described first valve seat and described second valve seat, described valve rod one end connects described flashboard, the other end connects turn switch, cavity and through hole is provided with in described flashboard, pressure relief component is provided with in described cavity, described pressure relief component can be stretched out or regain from described through hole, and described valve rod is connected with described pressure relief component by transmission part.
Preferably, above-mentioned a kind of can the plate valve of pressure release: described pressure relief component is connected by screw mandrel connecting rod with described valve rod.
Preferably, above-mentioned a kind of can the plate valve of pressure release: described through hole is one, and described pressure relief component can be stretched out and withdrawal from described through hole.
Preferably, above-mentioned a kind of can the plate valve of pressure release: described through hole is two, and described pressure relief component can be stretched out and withdrawal from described through hole.
Preferably, above-mentioned a kind of can the plate valve of pressure release: the side that described through hole is close to described first valve seat and described second valve seat is provided with sealed member.
Preferably, above-mentioned a kind of can the plate valve of pressure release: described pressure relief component is can one-way expansion or bi-directional expansion.
Outstanding effect of the present utility model is: 1) by pressure relief component, and to the pressure pressure release of valve plate, the extruding that the pressure that can reduce upstream liquid causes valve plate, ensures the good result of valve plate shape; 2) valve plate is separated with the valve seat of both sides by pressure relief component, and the sealing force between valve plate and valve seat can reduce, and is conducive to staff and carries out switching operations to plate valve easily.
Below just accompanying drawing in conjunction with the embodiments, is described in further detail embodiment of the present utility model, is easier to understand, grasp to make technical solutions of the utility model.
Accompanying drawing explanation
Fig. 1 is the structural representation of plate valve with position, end of embodiment 1;
Fig. 2 is the structural representation of the valve plate of embodiment 1.
Embodiment
As shown in Figure 1, this enforcement is a kind of can the plate valve of pressure release, and comprise valve seat, flashboard 1 and valve rod 4, said valve seat is divided into the first valve seat 2 and the second valve seat 3 for embodiment 1, flashboard 1 and being closely cooperated by seal ring between the first valve seat 2 and the second valve seat 3.One end of valve rod 4 connects flashboard 1, and the other end connects turn switch, and the rotating band ovable valve stem 4 of rotary switch rotates, thus drives valve plate 1 to rise or decline.
As shown in Figure 2, be provided with cavity and through hole 11 in flashboard 1, be provided with pressure relief component 5 in cavity, pressure relief component 5 is connected with valve rod 4 by leading screw connecting rod.The number of through hole 11 is one, is opened in arbitrary side of valve plate 1.The side that through hole 11 is close to the first valve seat 2 and the second valve seat 3 is provided with sealed member, for keeping the sealing of valve plate 1 entirety and valve seat.The rotarily driving pressure relief component 5 and can stretch out from through hole 11 or regain of valve rod 4, thus lean the first valve seat 2 or the second valve seat 3, can reach the object of pressure release, operator can easily by valve open or closedown.
The difference of embodiment 2 the present embodiment and embodiment 1 is: the through hole 11 on valve plate 1 is two, is distributed in the both sides of valve plate 1 respectively, and now, pressure relief component 5 can be stretched out and withdrawal to connecting a direction from two through holes 11, thus reaches the object of pressure release.
The utility model still has numerous embodiments, all employing equivalents or equivalent transformation and all technological schemes formed, and all drops within protection domain of the present utility model.
Claims (6)
