Abstract
The utility model discloses a high-temperature-resistant pressure retaining valve of a reaction kettle. The high-temperature-resistant pressure retaining valve comprises a valve, a ball and a valve stem. An inlet and an outlet which are coaxial with each other are respectively formed in two sides of the valve, the ball is arranged between the inlet and the outlet and is embedded inside the valve, and the valve stem is arranged on the top of the ball. The high-temperature-resistant pressure retaining valve is characterized in that a front valve seat and a rear valve seat are respectively arranged on two sides of the ball, a front valve seat sealing ring and a rear valve seat sealing ring are respectively arranged on the front valve seat and the rear valve seat, a compression ring is arranged on the outer side of the front valve seat sealing ring, and an elastic part is arranged on the compression ring and is used for compressing the front valve seat, the front valve seat sealing ring, the rear valve seat and the rear valve seat sealing ring, so that the front valve seat and the rear valve seat can be sealed with the valve. The high-temperature-resistant pressure retaining valve has the advantages of simple structure, reliable performance, high elastic compensation capacity and wide applicable temperature scope.
Description
Technical field
the utility model relates to a kind of pressure retaining valve, the high temperature resistant pressure retaining valve of especially a kind of reactor.
Background technique
in prior art pressure retaining valve due to have fluid resistance little, easy to operate, open and close rapidly, good airproof performance and reliability high, in industries such as petrochemical industry, long-distance transport pipes and urban heat supplyings, obtained application widely.In order to meet the needs of worst hot case, normal passing through optimized sealing configuration, and its open and close torque is obviously reduced in recent years, and greatly extend working life, and operating characteristics significantly improves.The sealed characteristic of pressure retaining valve is mainly to adopt metal-seated, and its advantage is that Applicable temperature scope is wide, and the thermal expansion coefficient of various metals is more or less the same, as long as select properly, can reach basically identical, is conducive to coordinate temperature deformation; Shortcoming is that material hardness is high, reaches the necessary specific pressure of sealing high, even if adopt pretightening force to reach sealing, but because seal pressure is large, the wearing and tearing between valve seat and spheroid are also very large, and because metallic sealing section friction factor is larger, cause opening and closing moment larger.
Summary of the invention
the utility model object is: provide a kind of simple in structure, and reliable performance, and elastic compensating ability is strong, the high temperature resistant pressure retaining valve of reactor that Applicable temperature scope is wide.
the technical solution of the utility model is: a kind of reactor is high temperature resistant pressure retaining valve, comprise valve body, spheroid and valve rod, described valve body both sides are respectively equipped with coaxial import and outlet, described spheroid is located between described import and described outlet and is embedded in described valve inner, described valve rod is located at described spheroid top, it is characterized in that, described spheroid both sides are respectively equipped with the front valve seat of valve and valve rear valve base, before described valve, on valve seat and described valve rear valve base, be respectively equipped with the front valve seat insert of valve and valve rear valve base seal ring, before described valve, valve seat insert outside is provided with pressure ring simultaneously, this pressure ring is provided with elastic component, described elastic component is for valve seat before compression valve and the front valve seat insert of valve and valve rear valve base and valve rear valve base seal ring, make the front valve seat of described valve and described valve rear valve base and described valve seal.
preferably, valve seat and described valve rear valve base be take the axle center of described valve rod as symmetry center and before embedding respectively the valve of described valve inner after embedded groove and valve in embedded groove before described valve.
preferably, described elastic component is the elastic component that polyimide material is made, and this polyimide material is high temperature resistant to be reached more than 400 ℃, and long-term serviceability temperature scope-200～300 ℃, have the performances such as high temperature resistant, corrosion-resistant.
preferably, before described valve, valve seat insert and described valve rear valve base seal ring are Expanded graphite RunddichtringO.
the utility model has the advantages that: not only simple in structure, the front valve seat insert of elastic component compression valve and the valve rear valve base seal ring that adopt polyimide material to make simultaneously, make the front valve seat of valve and valve rear valve base and valve seal, thereby make the utility model pressure retaining valve performance more reliable, elastic compensating ability is stronger, and Applicable temperature is wider.
