Abstract
The utility model discloses an automatic decoking plug valve, which comprises a valve body, a valve body lower cover, a valve rod, a plug and a sealing element, wherein the upper part of the valve body is provided with the valve rod. The automatic decoking plug valve is characterized in that an inlet passage and an outlet passage of the valve body are respectively provided with a tile-shaped valve seat which is matched with a plug, two side edges of each tile-shaped valve seat are made into a scraper-type structure with an acute angle, and a disc spring is arranged on a vertical contact surface of one tile-shaped valve seat and the valve body. The automatic decoking plug valve has the advantages that the tile-shaped valve seats are adopted to be matched with the plug for sealing, and the two side edges of each tile-shaped valve seat are made into the scraper-type structure with the acute angle, so that a coking material which is adhered on the surface of a plug body can be scraped in the opening and closing process of the valve, the abrasion of the sealing surface can be reduced, the sealing performance can be improved, and the service life of a product can be prolonged. Moreover, the spring is arranged between one tile-shaped valve seat and the valve body, so that the high-temperature expansion of the plug body can be prevented.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of hard sealing stopcock.
Background technique
Stopcock has hard sealing and 2 kinds of structures of soft seal, and the soft seal stopcock is applicable to low temperature, seals stopcock firmly and can be used for high temperature.Yet, common hard sealing stopcock, area of contact is big between cock and the valve body, and frictional force is big between the two in the opening-closing process, and open and close torque is big, and wearing and tearing are big between the sealing surface.For this reason; The patent No. is 002169800 hard sealing self lubricating plug valve, between valve seal conical bore and cock surface, makes the greasing groove, injects seal gease; Realize machinery and grease double seal; Keep the lubricity between the sealing surface, reduce keying frictional force and moment of torsion between the sealing surface, improve sealability.But when being used in the coking capacity medium operating mode of industries such as oil, chemical industry, in the valve opening and closing process, the coking material that is bonded in the faucet body surface will produce wearing and tearing to sealing surface, influence the sealability and the working life of valve.And under worst hot case, Yin Gaowen expands and stuck between faucet body and the valve body, can not normally open and close, and uses so be not suitable for worst hot case.
The model utility content
In order to overcome the deficiency of existing technology, the utility model provides a kind of cock surface coking material that in opening-closing process, can scrape off, and good seal performance, long service life, is suitable for the automatic decoking stopcock that worst hot case uses.
The utility model has adopted following technological scheme:
A kind of automatic decoking stopcock; Comprise valve body, valve body lower cover, valve rod, cock and Sealing; Valve body top is provided with valve rod, it is characterized in that, the import and export passage place of valve body is provided with 1 watt shape valve seat that cooperatively interacts with cock respectively; The scraper type structure of tool acute angle is processed in this watt shape valve seat both sides of the edge, and wherein 1 watt of shape valve seat is provided with the butterfly spring with the vertical surface of contact of valve body.
Preferably, the valve body lower cover is threaded with valve body, and cock lower end surface central authorities are provided with the sphere jacking block; Valve body lower cover central, threaded is connected with the push rod that carries cock; The push rod upper end is provided with the spherical groove that is complementary with jacking block, realizes the vertical support to faucet body, reduces the friction of cock bottom support face.
Preferably, push rod is through graphite packing and the sealing of valve body lower cover, and the two ends up and down of graphite packing are provided with the steel wire ring, and the following Gland that is located at the graphite packing below is threaded with the valve body lower cover, thereby graphite packing is fixed.
Preferably, valve rod is connected with cock through sliding connector; Said valve rod lower end is provided with bumping square, and said cock upper end is provided with square groove, the square groove that said link upper end is provided with and the bumping square of valve rod coincide, the bumping square that said link lower end is provided with and the square groove of cock coincide.Valve rod is connected with cock in this way, can avoid mismatch error, makes valve rod and cock when opening and closing, not have jam, reduces opening and closing torque.
Preferably, said valve rod and valve body are through the graphite packing sealing, and the two ends up and down of graphite packing are provided with the steel wire ring, and the last Gland that is located at the graphite packing top is threaded with valve body, thereby graphite packing is fixed.
Preferably, the sealing surface of said valve body and valve body lower cover is provided with seal ring.
Preferably, the said pad of going up when Gland is threaded with valve body and Gland is threaded with the valve body lower cover down adopts the butterfly spring.
Preferably, the two-port position is provided with hard wear-resistant material in the outer surface of said faucet body and the passage.
So the advantage of the utility model is adopting watt shape valve seat and the cock sealing that cooperatively interacts; The scraper type structure with acute angle is processed in watt shape valve seat both sides of the edge; In the valve opening and closing process, can scrape off the coking material that is bonded in the faucet body surface; Reduce the wearing and tearing of sealing surface, improve sealability, prolong product working life.And, be provided with spring between one of them watt shape valve seat and the valve body, it is dead to prevent that faucet body high temperature from expanding.
