Description
Technical field
This utility model relates to valve technology field, is specially a kind of pressure limiting valve.
Background technology
In daily life, a lot of places are required for using pipeline and carry out conveying and the water conservancy diversion of liquid, carry being used for
In the pipeline of liquid, often arranging pressure limiting valve in pipeline for protective conduit, the Main Function of pressure limiting valve is when liquid is at quilt
During conveying, when the excessive maximum that will exceed pipeline of pressure of duct wall be born by liquid, the pressure of liquid is carried out
Decompression, traditional pressure limiting valve structure is the most comparatively laborious, and manufacturing cost is high.
Utility model content
The purpose of this utility model is to provide a kind of pressure limiting valve, with the problem solving to propose in above-mentioned background technology.
The technical scheme that this utility model relates to:
A kind of pressure limiting valve, by pipeline, outer wall, places restrictions on block, spherical valve head, compression spring, piston, fixed dam, rubber
Gum cover, valve and through flow hole composition.
Described pipeline is T font.
Described pipeline is surrounded by outer wall.
One end of described pipeline is connected fixing by fixed dam with outer wall and closes.
Described spherical valve head is connected with fixed dam by compression spring.
Described connection has the compression spring of spherical valve head to be positioned at pipeline.
One end of described spherical valve head is fixed with in upper and lower two inner sides of outer wall and places restrictions on block.
Preferably, the outer wall of described compression spring is wrapped in rubber sleeve.
Preferably, between described compression spring, connection has piston.
Preferably, described piston is positioned at the bottom of pipeline and is fixedly connected with valve.
Preferably, described outer wall is positioned at the underface of valve and is provided with through flow hole.
Compared with prior art, the beneficial effects of the utility model are: this pressure limiting valve device, simple in construction, easily manufacture,
The design of spherical valve head is the most streamlined makes the flowing of liquid more unobstructed, and compression spring is enclosed with rubber sleeve can be more preferable
Preventing the rust of compression spring so that device is more durable, the piston arranged between compression spring connects has the valve can be according to pressure
The Flexible change of power spring moves freely, opening or closing of convenient control through flow hole.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. pipeline, 2. outer wall, 3. place restrictions on block, the most spherical valve head, 5. compression spring, 6. piston, 7. fixing gear
Plate, 8. rubber sleeve, 9. valve and 10. through flow holes.
Detailed description of the invention
With detailed description of the invention, this utility model is described further below in conjunction with the accompanying drawings.
This utility model as it is shown in figure 1, a kind of pressure limiting valve, by pipeline 1, outer wall 2, place restrictions on block 3, spherical valve head 4,
Compression spring 5, piston 6, fixed dam 7, rubber sleeve 8, valve 9, through flow hole 10 form.
Described pipeline 1 is in T font.
Described pipeline 1 is surrounded by outer wall 2.
One end of described pipeline 1 is connected fixing by fixed dam 7 with outer wall 2 and closes, arranging on the one hand of fixed dam 7
Pipeline 1 can be closed, on the other hand can also give the pressure that compression spring 5 is certain.
Described spherical valve head 4 is connected with fixed dam 7 by compression spring 5, and the design of spherical valve head 4 has streamlined making
The flowing of liquid is more unobstructed, it is to avoid the pipeline 1 that do not rapidly causes of causing because valve head is in irregular shape reducing pressure ruptures.
Described connection has the compression spring 5 of spherical valve head 4 to be positioned at pipeline 1.
One end of described spherical valve head 4 is fixed with in upper and lower two inner sides of outer wall 2 and places restrictions on block 3, places restrictions on block 3 and fixing gear
Plate 7 acts on the reset pressure certain to compression spring 5 jointly, it is to avoid liquid has not a particle of pressure in the process of flowing.
The outer wall of described compression spring 5 is wrapped in rubber sleeve 8, and rubber sleeve 8 can preferably prevent the rust of compression spring 5,
Make device more durable.
The bottom that described piston 6 is positioned at pipeline 1 is fixedly connected with valve 9, and valve 9 can be according to the Flexible change of compression spring 5
Move freely, opening or closing of convenient control through flow hole 10.
The underface that described outer wall 2 is positioned at valve 9 is provided with through flow hole 10.
