Problems solved by technology

[0005] 2. Since the device adopts a double valve stem structure, and the first valve core and the second valve core need to be arranged side by side in the axial direction, the overall height of the valve is relatively large, resulting in a large space occupied by the packaging and transportation of the device, which is not convenient for installation Install and use in small and limited space

Abstract

The invention discloses a dual-seal valve for a high-pressure high-temperature equal-fluid pipe based on ball column embedding dual-seal and belongs to the technical field of pipe valves. The dual-seal valve comprises a valve body, the left and right sides of the valve body are respectively provided with a medium inlet and a medium outlet which are communicated with an inner cavity of the valve body, and the top of the inner cavity of the valve body is provided with a valve element sleeve; an inner cavity of the valve element sleeve is communicated with the medium outlet and provided with a valve rod, and the top of the valve rod is provided with a rotation disc handle; the bottom of the inner cavity of the valve body is provided with a valve element base, the top of the valve element baseabuts against a column valve element, an inner cavity of the column valve element is provided with a ball valve element, and the top of the column valve element is connected with the bottom of the valve rod. The dual-seal valve for the high-pressure high-temperature equal-fluid pipe based on ball column embedding dual-seal is provided, which helps to improve use durability and leakproofness of the valve. The dual-seal valve can reduce the occupation space during packaging and transportation and is conveniently installed and used in a narrow limited space.

Description

technical field [0001] The invention relates to the technical field of pipeline valves, in particular to a double-seal valve for high-pressure, high-temperature and other fluid pipelines based on ball-column phase-embedded double-seal. Background technique [0002] Existing valves on pipelines for transporting high-temperature and high-pressure media include a valve body, and the two sides of the valve body are respectively provided with a medium pipeline inlet and a medium pipeline outlet; the medium pipeline inlet is located at the end of the valve body and the medium pipeline outlet is located at the end of the valve body They are the inlet end and the outlet end respectively; the inlet end and the outlet end communicate with the cavity opened in the vertical direction in the center of the valve body; in order to realize the connection and cut-off of the medium pipeline inlet and the medium pipeline outlet, the current valve is a primary seal, that is, Relying on a spool ...
