Abstract
The utility model provides a but pressure release butterfly valve, 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 body, the downthehole pressure relief block that is provided with of pressure release. The beneficial effects of the utility model are that: 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 the pressure release is downthehole place pressure relief block on, when pressure was too big in the pipeline, pressure relief block moved backward, the pressure release hole can be opened, pipeline is downwards arranged via the pressure release hole to the medium.
Description
Technical field
This utility model belongs to pipe control apparatus field, and more particularly, to one kind can pressure release butterfly valve.
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, or even medium is arranged outwardly, causes environment
Pollution.
Content of the invention
In order to solve above-mentioned technical problem, this utility model provide one kind can pressure release butterfly valve, including valve body, valve seat, upper valve
Bar, 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 lower portion and institute
State valve seat to connect it is characterised in that being provided with implant between described lower valve rod and described valve body, described implant is provided with sealing gasket
Circle, described valve body is provided with relief hole, and described pressure release in the hole is provided with pressure release block.
Also include dye orifice, described dye orifice is located in described valve body, and connects with described relief hole, described dye orifice end
End is provided with translucent cover, and described pressure release block end is provided with dyestuff.
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 pressure release in the hole is placed on pressure release block, when pressure is excessive in pipeline, move after pressure release block, relief hole meeting
Open, medium is via relief hole row's pipeline downwards；Using dye orifice and dyestuff, after the displacement of pressure release block, dyestuff can flow into dyestuff
Hole, is easy to related personnel and finds that the relief hole of this butterfly valve has already turned in time.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of relief hole 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, dye orifice；10th, dyestuff；11st, relief hole.
As shown in Figure 1, 2, flap 5 is located in valve body 1, and is connected with upper valve rod 3, lower valve rod 4, valve body 1 bottom and valve seat 2
Connect, be provided with implant 6 between lower valve rod 4 and valve body 1, implant 6 is provided with seal washer 7.Valve body 1 is provided with relief hole 11,
It is provided with pressure release block 8 in relief hole 11.Dye orifice 9 is located in valve body 1, and connects with relief hole 11, and dye orifice 9 end is provided with
Bright cover, pressure release block 8 end is provided with dyestuff 10.Pressure release block 8 can be any geometry, and in the present embodiment, the section of pressure release block 8 is
Circular.Relief hole 11, pressure release block 8 adopt different model according to the use pressure requirements of different pipelines.The area of section of dye orifice 9
Area of section less than relief hole 11.
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.
