Abstract
The utility model provides a stop valve, including valve body, valve clack, valve rod, valve gap and handle, be equipped with the disk seat in the valve body, the valve clack is located the disk seat, the valve gap pass through the bolt fastening in on the valve body, the valve rod runs through valve gap and valve body, its lower extreme with the valve clack is connected, the upper end with the handle is connected, be provided with the filler between valve gap and valve rod, the filler is provided with seal ring from top to bottom respectively, be equipped with the pressure release hole on the disk seat, the downthehole pressure relief block that is provided with of pressure release. Beneficial effect does: use the filler between valve rod and valve gap, the filler sets up seal ring from top to bottom respectively, can reduce the friction between lower valve rod and valve body, reduces wearing and tearing, improves the leakproofness between valve rod and valve gap simultaneously, set up the pressure release hole on the disk seat 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, more particularly, to a kind of stop valve.
Background technology
Stop valve refers to closure member (flap) along the valve of valve seat centrage movement, and flap makees straight line along the centrage of valve seat
Motion, due to the valve rod of such valve, to be turned on and off stroke relatively short, and has very reliable cutting function, and by
In change and the stroke direct proportionality of flap of valve seat port, it is very suitable for the regulation to flow, therefore, this type
The shutoff valve that dams be highly suitable as cut off or adjust and throttling use.Stop valve is once in opening, its valve
Just no longer there is contact between seat and valve clack sealing surface, when it is closed, there is very reliably cut-out action, thus its sealing
Face mechanical wear is less, because the valve seat of most of stop valve and flap are easier to repair or replacing, therefore works as potted component
During damage, whole valve need not be removed from pipeline, this is very applicable for valve and pipeline welding all-in-one-piece occasion
's.
Stop valve is a kind of fully switched on or the closed circuit valve of cut-out pipeline, and it is widely used, often in the row such as oil, chemical industry
It is used for control piper medium in industry to circulate.Existing stop valve, when sealing to filler, is added a cover for general on filler
One layer of follower, its sealing is not high, and after employing a period of time, its valve gap, valve stem contacts part occur abrasion, easily
The situation of seepage occurs.In addition, the pipeline that stop valve is located is when the excessive situation of pressure, without dress relief valve or let out
Pressure valve does not have normal work, can cause the damage of pipeline component, and medium is arranged outwardly, pollutes environment.
Content of the invention
In order to solve above-mentioned technical problem, this utility model provides a kind of stop valve, including valve body, flap, valve rod, valve gap
And handle, it is provided with valve seat in described valve body, described flap is located on valve seat, and described valve gap is secured by bolts in described valve body
On, described valve rod runs through described valve gap and valve body, and its lower end is connected with described flap, and upper end is connected with described handle, its feature
It is, be provided with implant between described valve gap and valve rod, described implant is respectively arranged with seal washer up and down, on described valve seat
It is provided with relief hole, 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: use implant in valve rod and valve cover chamber, implant is respectively provided with close up and down
Seal washer, it is possible to reduce the friction between lower valve rod and valve body, reduces abrasion, improves the sealing of valve rod and valve cover chamber simultaneously；?
Open up relief hole on valve seat, 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
Can 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 dye
Material hole, is easy to related personnel and finds that the relief hole of this stop valve has already turned in time.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the enlarged drawing of a of Fig. 1.
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, flap；3rd, valve rod；4th, valve gap；5th, handle；6th, pressure release block；7th, relief hole；8th, implant；9、
Seal washer；10th, valve seat；11st, dye orifice；12nd, dyestuff.
As shown in Figure 1, 2, it is provided with valve seat 10 in described valve body 1, described flap 2 is located on valve seat 10, and described valve gap 4 passes through
Bolt is fixed on described valve body 1, and described valve rod 3 runs through described valve gap 4 and valve body 1, and its lower end is connected with described flap 2, on
End is connected with described handle 5, is provided with implant 8, described implant is respectively arranged with close about 8 between described valve gap 4 and valve rod 3
Seal washer 9.Described valve seat 10 is provided with relief hole 7, is provided with pressure release block 6 in described relief hole 7.Described dye orifice 11 is located at institute
State in valve body 1, and connect with described relief hole 7, described dye orifice 7 end is provided with translucent cover, described pressure release block 6 end is provided with dye
Material 12.Pressure release block 6 can be any geometry, and in the present embodiment, the section of pressure release block 8 is circle.Relief hole 7, pressure release block 6
Use pressure requirements according to different pipelines adopt different model.The area of section of dye orifice 11 is less than the area of section of relief hole 7.
When pressure is excessive in pipeline, moves after pressure release block 6, dyestuff 12 is extruded to dye orifice 11, no longer stop relief hole 7 simultaneously, cut
The only pipeline connection of valve both sides.
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
