Abstract
The utility model is related to valve technology field, more particularly to a kind of U-shaped graphite combined sealing structure of high-temperature metal.The U-shaped graphite combined sealing structure of the high-temperature metal, including valve body, bonnet and seating spring.The purpose of this utility model is to change silication work and the sealing structure of coal chemical industry ball seat and bonnet, so as to improve the effect of valve base sealing, extends valve base sealing service life.Further increase valve service life, and save the production cost of silicon coal chemical industry enterprises.Graphite is easily by medium erosion failure, so graphite grazing can not be leaned on only, and some high duty metals are resistance to erosion, and high temperature resistant.Main seal can be used as.Therefore select the U-shaped circle of metal of pressure self-sealing and Graphite pad combination to replace original graphite grazing.Simultaneously leakage problem is effectively solved by boring the method for pressure compensation opening close at sealing surface on U-shaped circle top.
Description
Technical field
The utility model is related to valve technology field, more particularly to a kind of U-shaped graphite combined sealing structure of high-temperature metal.
Background technology
Valve silication work and coal chemical industry application are more and more extensive, and the valve of pipeline various functions is controlled in process of production
Door is essential.Ball valve has simple in construction, and switch is rapid, the advantages of flow resistance is small, can be cut off, distribution and changes medium flow direction etc.
Numerous purposes, play critically important effect in pipeline transportation.However, the mal-condition such as high temperature, height wash away, tiny solid medium
So that the life-span of ball valve is very short in the industry.How to overcome every problem, extend valve service life, be improve production efficiency and
Reduce the effective way of production cost.
Currently, the most silication work of in the market and coal chemical industry ball valve carry out valve seat and spheroid using materials such as metal, ceramics
Directly seal, the sealing of valve seat and bonnet then uses simple flexible graphite sealing, because soft graphite can be resistant to more than 1,000
Degree Celsius high temperature.However, because silication work and coal chemical industry medium are fine particle, and hardness is very high.Although many valves
Dustproof construction is devised to prevent medium from entering sealing surface of seat, carbon seal ring is damaged, but effect is undesirable.It is close
The service life of seal is still very short.
Utility model content
In order to overcome defect present in background technology, the utility model solves the technical scheme that its technical problem is used
It is：A kind of U-shaped graphite combined sealing structure of high-temperature metal, including valve body, bonnet and seating spring, the bonnet is by fastening spiral shell
Nail is fixed on the both sides of valve body, and the inside of the valve body is provided with spheroid and valve seat, and the valve body is provided with gear-box, the gear
Case is provided with handwheel, and seating spring and packing are provided between the bonnet and valve seat, ladder is formed between the bonnet and valve seat
Provided with the U-shaped circle one of metal and Graphite pad one, the U-shaped circle of the metal in interface one and ladder interface two, the ladder interface one
One opening direction is towards valve seat, and the Graphite pad one is arranged between the bottom of the U-shaped circle one of metal and bonnet, the ladder
Provided with the U-shaped circle two of metal and Graphite pad two in interface two, the opening direction of the U-shaped circle two of metal is towards bonnet, the stone
Ink pad piece two is arranged between the bottom of the U-shaped circle two of metal and valve seat.
It is preferred that the metal it is U-shaped circle one and metal it is U-shaped circle two be provided with pressure compensation opening.
The purpose of this utility model is to change silication work and the sealing structure of coal chemical industry ball seat and bonnet, so as to carry
The high sealed effect of valve seat, extends valve base sealing service life.Further increase valve service life, and save silicon coal chemical industry enterprise
The production cost of industry.Graphite is easily by medium erosion failure, so graphite grazing can not be leaned on only, some high duty metals are resistance to punching
Brush, and high temperature resistant.Main seal can be used as.Therefore select the U-shaped circle of metal and Graphite pad of pressure self-sealing to combine and replace
Original graphite grazing.Effectively solved by boring the method for pressure compensation opening close at sealing surface on U-shaped circle top simultaneously
Leakage problem.
A kind of beneficial effect for the U-shaped graphite combined sealing structure of high-temperature metal that the utility model is related to also includes：
1st, the advantages of endurance life-span of the U-shaped circle of metal is high, voltage endurance capability is strong, temperature in use scope is wide.Can be according to difference
Operating mode is used as raw material from corrosion resistant metal.
2nd, the U-shaped circle of metal and Graphite pad combination sealing have two seals, and the U-shaped circle of metal makees primary seal, and Graphite pad is made
Auxiliary seal, makes valve safer, and service life is longer.
3rd, the U-shaped circle of metal carries elastic packing function using groove compression, and coordinates the pressure compensation opening itself designed, makes
Obtaining under environment under low pressure also has good sealing effectiveness.
4th, Graphite pad is i.e. as auxiliary seal, and playing again prevents pressure from repeatedly colliding U-shaped circle, makes U-shaped circle or sealing ditch
The effect that groove is damaged.
