Abstract
The invention discloses a kind of high-temperature wearable hard seal ball valve seat with dustproof construction, including valve body, cylindrical spring, spring base, sealing ring, valve seat and spheroid, the valve seat location of the valve body is provided with dust-proof sleeve pipe, and multiple tracks groove is offered on dust-proof sleeve pipe, soft graphite is filled with groove.The present invention designs dust-proof sleeve pipe in valve seat location, twice groove is processed on dust-proof sleeve pipe and is used for filling flexible graphite, it is allowed to prevent the particulate matters such as the dust in medium, slurries from entering spring base and cylinder preloading spring is lost due function, the reliability of valve seal is ensure that, improves valve service life.
Description
Technical field
The present invention relates to technical field of valve manufacturing, specifically a kind of high-temperature wearable hard seal ball valve with dustproof construction
Valve seat.
Background technology
Contain dust, particle, slurries etc. in the fields such as oil, chemical industry, coal chemical industry, its processing medium, this kind of medium
Feature is easy solidification coking.Under such working condition, abrasion-proof hard seal Fixed ball valve has just obtained good application.Its
In, the preloading spring at valve seat is favored by designer very much from the situation of disc spring, if because from cylindrical spring, works as technique
After medium enters spring eye coking or solidification, spring can be hindered to play the effect of its pretension, make the seal break-off of valve.This just needs
A kind of Novel valve seat structure is researched and developed, to ensure that valve meets above-mentioned working condition at work, ensures the service life of valve.
The content of the invention
It is an object of the invention to provide a kind of high-temperature wearable hard seal ball valve seat with dustproof construction, with solution
State the problem of being proposed in background technology.
To achieve the above object, the present invention provides following technical scheme：
A kind of high-temperature wearable hard seal ball valve seat with dustproof construction, including it is valve body, cylindrical spring, spring base, close
Seal, valve seat and spheroid, the valve seat location of the valve body are provided with dust-proof sleeve pipe, twice groove, ditch are offered on dust-proof sleeve pipe
Soft graphite is filled with groove, the cylindrical spring provides a pretightning force push the spring seat compresses seal, is formed at the beginning of one
Beginning seal pressure.
As the further scheme of the present invention：The section of the groove is square.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention designs dust-proof sleeve pipe in valve seat location, dust-proof
Twice groove is processed on sleeve pipe and is used for filling flexible graphite, is allowed to prevent the particulate matters such as the dust in medium, slurries from entering bullet
Spring abutment makes cylinder preloading spring lose due function, ensure that the reliability of valve seal, improves valve service life.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
In figure：1- valve bodies, 2- soft graphites, 3- cylindrical springs, the dust-proof sleeve pipes of 4-, 5- spring bases, 6- sealing rings, 7- valves
Seat, 8- spheroids.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Referring to Fig. 1, in the embodiment of the present invention, a kind of high-temperature wearable hard seal ball valve seat with dustproof construction, bag
Include valve body 1, cylindrical spring 3, spring base 5, sealing ring 6, valve seat 7 and spheroid 8, the position of valve seat 7 of the valve body 1 is provided with dust-proof
Sleeve pipe 4, twice groove is offered on dust-proof sleeve pipe 4, soft graphite 2 be filled with groove, for preventing dust in medium, starching
The particulate matters such as liquid enter spring base 5, i.e., in the clearance t 1 and t2 in figure, efficiently solve processing medium in spring base 5, close
Coking or solidification cause the situation of seal failure at seal 6, avoid cylindrical spring 3 from losing due function, ensure that valve is close
The reliability of envelope, improve valve service life.
The cylindrical spring 3 provides a compresses seal 6 of pretightning force push the spring seat 5, forms an initial sealing ratio
Pressure.
Preferably, the section of the groove is square.
The present invention designs dust-proof sleeve pipe 4 at the position of valve seat 7, and twice groove is processed on dust-proof sleeve pipe 4 and is used for filling flexible
Graphite 2, is allowed to prevent the particulate matters such as the dust in medium, slurries to enter spring base 5 that to lose cylinder preloading spring 3 due
Function, the reliability of valve seal is ensure that, improve valve service life.
The above is only the preferred embodiment of the present invention, it is noted that for those skilled in the art, not
On the premise of departing from present inventive concept, several modifications and improvements can also be made, these should also be considered as the protection model of the present invention
Enclose, these effects and practical applicability for implementing all without the influence present invention.
