Abstract
The utility model discloses a kind of high-temperature wearable hard seal ball valve seats with dustproof construction, including valve body, cylindrical spring, spring base, sealing ring, valve seat and sphere, the valve seat location of the valve body is equipped with dust-proof casing, multiple tracks groove is offered on dust-proof casing, soft graphite is filled in groove.The utility model designs dust-proof casing in valve seat location, twice groove is processed on dust-proof casing 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 made to lose due function, it ensure that the reliability of valve seal, improve valve service life.
Description
Technical field
The utility model is related to technical field of valve manufacturing, are specifically that a kind of high-temperature wearable with dustproof construction seals firmly
Ball seat.
Background technology
In fields such as oil, chemical industry, coal chemical industries, dust, particle, slurries etc. are contained in 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 selects the situation of disc spring to be favored by designer very much, if this is because selection cylindrical spring, works as technique
After medium enters spring eye coking or solidification, spring can be hindered to play its preload effect, make the seal break-off of valve.This is just needed
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.
Utility model content
The purpose of this utility model is to provide a kind of high-temperature wearable hard seal ball valve seat with dustproof construction, with solution
Certainly the problems mentioned above in the background art.
To achieve the above object, the utility model provides following technical solution：
A kind of high-temperature wearable hard seal ball valve seat with dustproof construction, including valve body, cylindrical spring, spring base, close
Seal, valve seat and sphere, the valve seat location of the valve body are equipped with dust-proof casing, multiple tracks groove, ditch are offered on dust-proof casing
Soft graphite is filled in slot.
As further program of the utility model：It is close that the cylindrical spring provides a pretightning force push the spring seat compression
Seal forms an initial sealing than pressure.
As further program of the utility model：Twice groove is offered on the dust-proof casing.
As further program of the utility model：The section of the groove is square.
Compared with prior art, the beneficial effects of the utility model are：The utility model designs dirt-proof boot in valve seat location
Pipe, on dust-proof casing processing twice grooves is used for filling flexible graphite, is allowed to prevent the particulate matters such as dust, slurries in medium
Matter, which enters spring base, makes cylinder preloading spring lose due function, ensure that the reliability of valve seal, and improving valve makes
Use the service life.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
In figure：1- valve bodies, 2- soft graphites, 3- cylindrical springs, the dust-proof casings of 4-, 5- spring bases, 6- sealing rings, 7- valves
Seat, 8- spheres.
Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
Referring to Fig. 1, in the utility model embodiment, a kind of high-temperature wearable hard seal ball valve valve with dustproof construction
Seat, including valve body 1, cylindrical spring 3, spring base 5, sealing ring 6, valve seat 7 and sphere 8,7 position of the valve seat installation of the valve body 1
There is dust-proof casing 4, twice groove is offered on dust-proof casing 4, soft graphite 2 is filled in groove, for preventing in medium
The particulate matters such as dust, slurries enter spring base 5, i.e., in the clearance t 1 and t2 in figure, efficiently solve processing medium in bullet
Coking or solidification cause the situation of seal failure at spring abutment 5, sealing ring 6, and cylindrical spring 3 is avoided to lose due function, ensure
The reliability of valve seal, improves valve service life.
The cylindrical spring 3 provides 5 compresses seal 6 of pretightning force push the spring seat, forms an initial sealing ratio
Pressure.
Preferably, the section of the groove is square.
The utility model designs dust-proof casing 4 at 7 position of valve seat, and twice groove is processed on dust-proof casing 4 and is used for filling
Soft graphite 2, be allowed to prevent the particulate matters such as the dust in medium, slurries enter spring base 5 make cylinder preloading spring 3 lose should
Some functions ensure that the reliability of valve seal, improve valve service life.
Above is only the preferred embodiment of the utility model, it is noted that for those skilled in the art,
Without departing from the concept of the premise utility, several modifications and improvements can also be made, these should also be considered as this practicality
New protection domain, these all do not interfere with the effect and practical applicability of the utility model implementation.
