Abstract
The utility model relates to an uranium enrichment technical field specifically discloses a special filler formula right angle valve of hex. This right angle valve includes valve body, gland nut, sealing filler, gland and valve rod, and wherein, the valve body is cylinder section of thick bamboo structure in vertical direction to arch in cylinder section of thick bamboo lateral wall formation horizontally cylinder section of thick bamboo structure makes the valve body form the passageway of vertical direction and horizontal direction intercommunication, the valve rod is installed in the passageway of the vertical direction of valve body upper end, and the helicitic texture of valve rod lower extreme cylinder outer wall and valve body upper end are close to the screw thread phase -match of horizontal through -hole department, and valve rod circular conical surface structure bottom can realize the linear sealing with valve body lower part passway, annular space packing between valve rod upper end cylinder outer wall and the valve body inner wall has sealing filler and utilizes gland to compress tightly fixedly. A special filler formula right angle valve of hex, possess the ability of bearing than high pressure load, possess higher passageway leak rate and the requirement of valve body leak rate simultaneously.
Description
Technical field
This utility model belongs to uranium-enrichment technology field, is specifically related to a kind of hex filler special formula right-angle valve.
Background technology
At present, uranium enrichment field little volume hex container special valve is bellows-type flange external screw thread right angle vacuum valve, and it is primarily adapted for use in vacuum system, and it is relatively low to bear pressure capability, is up to 0.6MPa.Along with the International standardization of the improvement of Technology and hex container, the bearing capacity of the little volume hex container of China will be increased to 1.4MPa, and existing valve cannot meet working condition requirement.
Summary of the invention
The purpose of this utility model is in that to provide a kind of hex filler special formula right-angle valve, and it can not only meet passage and valve body leak rate is not more than 10-7Pa L/s and 10-8The vacuum level requirements of Pa L/s, and the intrinsic pressure of 1.4MPa can be born, meet the working condition requirement of little volume hex container matched use.
The technical solution of the utility model is as follows: a kind of hex filler special formula right-angle valve, this right-angle valve includes valve body, sealing nut, airtight and watertight padding, gland and valve rod, wherein, valve body is cylindrical structure at vertical direction, and the projection of the cylindrical structure of level is formed at cylindrical drum sidewall, make valve body form the passage vertically and horizontally connected；Valve rod is arranged in the passage of valve body vertical direction upper end, and the helicitic texture of valve rod lower end cylindrical body outer wall and the valve body upper end screw thread near horizontal through hole place match, and the part pyramid like configuration of valve rod bottom can realize linear sealing with valve body lower portion passway；Annular space between valve rod upper end cylindrical body outer wall and valve interior wall is filled with airtight and watertight padding and utilizes gland to be fixed.
The described valve body upper end screw thread near horizontal through hole place is trapezoidal thread.
The helicitic texture of the nut through valve rod upper end and valve body external wall of upper portion is passed through in described gland upper end, gland and airtight and watertight padding is fixed.
Described airtight and watertight padding is politef.
Screw thread between described valve body and valve rod has self-locking performance, and is controlled the aperture of valve by the size of pitch.
The cylindrical end face of described body wall compresses polytetrafluoroethylene sealing gasket by gland nut and realizes exit seal.
Described valve body lower end adopts NPT3/4 seal pipe screw thread and it is carried out the tining process sealing to ensure import.
Described valve body adopts copper material；Described valve rod adopts the nickel hardfacing alloy that flow harden processes to make.
Remarkable result of the present utility model is in that: a kind of hex filler special formula right-angle valve described in the utility model, possesses the ability bearing elevated pressures load, is provided simultaneously with higher passage leak rate and valve body leak rate requirement.
