Abstract
The utility model provides a butterfly valve with pressure release function, including valve body, disk seat, upper valve rod, lower valve rod and valve clack, the valve clack is located the valve body, and with upper valve rod, lower valve rod are connected, the valve body lower part with the disk seat is connected, the lower valve rod with be equipped with the filler between the valve body, be equipped with seal ring on the filler, be equipped with the pressure release hole on the valve clack, be provided with pressure relief block on the pressure release hole, be equipped with on the valve clack back and keep off the frame, it is just right to keep off the frame pressure relief block. Beneficial effect does: use the filler between lower valve rod and valve body, set up seal ring on the filler, can reduce the friction between lower valve rod and valve body, reduce wearing and tearing, improve the leakproofness between lower valve rod and valve body simultaneously, set up the pressure release hole on the valve clack to block up on the pressure release hole with pressure relief block, when pressure was too big in the pipeline, the pressure release hole can be opened, and the medium is arranged to the pipeline below via the pressure release hole, keeps off the frame and can prevent that pressure relief block from getting into in the pipeline.
Description
Technical field
This utility model belongs to pipe control apparatus field, more particularly, to a kind of butterfly valve with decompression function.
Background technology
Butterfly valve refers to that closure member is disk, rotates to reach a kind of valve of open and close around valve shaft, main on pipeline
Play cut-out and throttling action.The feature of the special butterfly valve of industry can be high temperature resistant, and applicable pressure limit is also higher, and valve latus rectum is big,
Valve body adopts carbon steel manufacture, and the sealing ring of valve plate adopts becket to replace rubber ring.Industrial butterfly valve be applied to producer, coal gas,
Various corruption are conveyed in the engineering systems such as natural gas, liquefied petroleum gas, town gas, air, chemical industry smelting and generation environment-friendly
On corrosion, the pipeline of non-corrosive fluids medium, for adjusting and blocking the flowing of medium.After but butterfly valve is long-time, its valve
Wearing and tearing easily occurs in seating portion, and leakage scenarios.And the pipeline that butterfly valve is located is when the excessive situation of pressure, if do not had
There are dress relief valve or relief valve there is no normal work, the damage of pipeline component can be caused, medium is arranged outwardly.
Content of the invention
In order to solve above-mentioned technical problem, this utility model provides a kind of butterfly valve with decompression function, including valve body, valve
Seat, upper valve rod, lower valve rod and flap, described flap is located in valve body, and is connected with described upper valve rod, lower valve rod, described valve body
Bottom is connected it is characterised in that being provided with implant between described lower valve rod and described valve body with described valve seat, and described implant sets
There is seal washer, described flap is provided with relief hole, described relief hole is provided with pressure release block, the described flap back side is provided with gear
Frame, described divider is just to described pressure release block.
The section of described pressure release block is circle.
The beneficial effects of the utility model are: using implant between lower valve rod and valve body, implant arranges sealing gasket
Circle, it is possible to reduce the friction between lower valve rod and valve body, reduces abrasion, improves the sealing between lower valve rod and valve body simultaneously；In valve
Open up relief hole on lobe, and get lodged on relief hole with pressure release block, when pressure is excessive in pipeline, relief hole can be opened, medium warp
Arrange to below pipeline from relief hole, divider can prevent pressure release block from entering in pipeline.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Below with reference to accompanying drawings this utility model is described in more detail, which show of the present utility model preferred
Embodiment is it should be appreciated that those skilled in the art can change this utility model described here and still realize this utility model
Advantageous effects.Therefore, description below be appreciated that widely known for those skilled in the art, and be not intended as right
Restriction of the present utility model.
In figure, 1, valve body；2nd, valve seat；3rd, upper valve rod；4th, lower valve rod；5th, flap；6th, implant；7th, seal washer；8th, let out
Briquetting；9th, divider.
As shown in figure 1, flap 5 is located in valve body 1, and it is connected with upper valve rod 3, lower valve rod 4, valve body 1 bottom is with valve seat 2 even
Connect, between lower valve rod 4 and valve body 1, be provided with implant 6, implant 6 is provided with seal washer 7.Flap 5 is provided with relief hole, pressure release
Pressure release block 8 is provided with hole, flap 9 back side is provided with divider 9, and divider 9 is just to pressure release block 8.Pressure release block 8 can be any geometric form
Shape, in the present embodiment, the section of pressure release block 8 is circle, 9 one-tenth rice fonts of divider.Pressure release block 8 is according to the use pressure of different pipelines
Requirement adopts different model.Hole on divider 9 is less than the size of pressure release block 8, after pressure release block 8 is washed open by medium, can be kept off by divider 9
Live.
It has been described in detail to of the present utility model above by embodiment, but described content is only of the present utility model
Preferred embodiment is it is impossible to be considered for limiting practical range of the present utility model.All made according to this utility model application range
Impartial change and improvement etc., all should still belong within patent covering scope of the present utility model.
