Abstract
The utility model discloses a kind of hydraulic flat plate valve, comprise valve body, valve rod and valve plate, described valve body is provided with the space holding described valve rod and valve plate, described valve rod is provided with the screw thread matched with described valve body, be provided with hydraulic pressure cavity in described valve body, described valve rod is positioned at described hydraulic pressure cavity, is connected between described valve rod with described valve plate by pressing plate, described pressing plate is positioned at the bottom of described hydraulic pressure cavity, and described valve plate is positioned at the bottom of described pressing plate.The technical program can cushion the impact force of outer bound pair flap type, and normally can work under rugged environment.
Description
Technical field
The utility model relates to machinery valve field, especially relates to a kind of hydraulic flat plate valve.
Background technique
Valve controls very important parts in pipeline transport and flow of fluid operation.Especially in petroleum pipeline and natural gas line, pipeline bears very large pressure, and the sealing of valve and anti-pressure ability determine the Safety performance of pipeline transport.Existing ducted valve is mechanical valve, completes opening of valve and closes, and need manual operation by screw thread rotation mechanism.But in rugged environment, such as: plateau section, extremely frigid zones, valve needs to carry out special process, to prevent corrosion to valve and freezing valve, the something unexpected happened when carrying out safeguarding and process emergency incident.The means of process are also from the original development being packaged into Latest Materials, but no matter are that effect is undesirable or financial cost is too high, and the problem that valve can not resist the aspects such as severe cold weather, buffering liquid pressure and ambient pressure is still still given prominence to.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the purpose of this utility model proposes a kind of hydraulic flat plate valve.
The purpose of this utility model will be achieved by the following technical programs: a kind of hydraulic flat plate valve, comprise valve body, valve rod and valve plate, described valve body is provided with the space holding described valve rod and valve plate, described valve rod is provided with the screw thread matched with described valve body, be provided with hydraulic pressure cavity in described valve body, described valve rod is positioned at described hydraulic pressure cavity, is connected between described valve rod with described valve plate by pressing plate, described pressing plate is positioned at the bottom of described hydraulic pressure cavity, and described valve plate is positioned at the bottom of described pressing plate.
Preferably, above-mentioned a kind of hydraulic flat plate valve: described hydraulic pressure cavity is connected with the inner wall sealing of described valve body.
Preferably, above-mentioned a kind of hydraulic flat plate valve: the bottom of described hydraulic pressure cavity and top are movable.
Preferably, above-mentioned a kind of hydraulic flat plate valve: described valve rod and described hydraulic pressure cavity are sealed by seal ring.
Preferably, above-mentioned a kind of hydraulic flat plate valve: the inwall of described valve body is provided with the limiting stopper limiting described hydraulic pressure cavity and move up and down.
Outstanding effect of the present utility model is: 1) in original flap type, arrange hydraulic pressure cavity, can be distributed in hydraulic pressure by impact force, cushion the destruction of causing flap type; 2) mechanical structure that liquid in hydraulic pressure cavity is different and simple, can protect valve rod to be corroded or freezing under the rugged environment such as severe cold, ensures the smoothness of operation; 3) valve rod is connected by pressing plate with valve plate, and when hydraulic pressure cavity Volume Changes, pressure uniform can be dispersed on valve plate by briquetting, prevents the too small stability problem causing valve plate of the lifting surface area of valve plate.
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 a kind of hydraulic flat plate valve of the present embodiment.
Embodiment
As shown in Figure 1, a kind of hydraulic flat plate valve of the present embodiment, comprises valve body 1, valve rod 2 and valve plate 3, and valve body 1 is provided with the space holding valve rod 2 and valve plate 3, the passage that valve body 1 separately has for liquid or gas passes through.Valve rod 2 is provided with the screw thread matched with valve body 1, and valve rod 2 and valve body 1 are relatively rotated by screw thread, thus axial displacement occurs.Be provided with hydraulic pressure cavity 4 in valve body 1, valve rod 2 is positioned at hydraulic pressure cavity 4 and is sealed by seal ring with hydraulic pressure cavity 4.Be connected by pressing plate 5 between valve rod 2 with valve plate 3, pressing plate 3 is positioned at the bottom of hydraulic pressure cavity 4, and valve plate 3 is positioned at the bottom of pressing plate 5.
The inwall of hydraulic pressure cavity 4 and valve body 1, for being tightly connected, ensures can not be deep in hydraulic pressure cavity 4 by the gas of valve body or liquid.And the bottom of hydraulic pressure cavity 4 and top are movable, namely the space of hydraulic pressure cavity 4 is variable spaces, the rise and fall of valve plate 3 of the reacting condition in this space.In order to limit the spatial variations of hydraulic pressure cavity 4, the inwall of valve body 1 is provided with the limiting stopper 6 that restriction hydraulic pressure cavity 4 moves up and down.
When rotary valve rod 2, valve rod 2 is by the rotational translation of screw thread for moving axially, and the space promoting hydraulic pressure cavity 4 changes, thus the bottom of hydraulic pressure cavity 4 promotes valve plate 3 moves down, and stops passage.
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 (5)
