Embodiment Construction

[0019] In order to better understand the shape, structure and characteristics of the present invention, preferred embodiments will be listed below and described in detail with reference to the accompanying drawings.

[0020] The valve switch with pressure of the present invention includes a clamp seat 5, which is composed of left and right parts, with a circular opening 51 in the middle. The opening 51 has two specifications of 60mm and 80mm, and can be clamped on At the circular opening of the adapter seat on the pressure vessel, the clamp seat 5 is tightened left and right by a plurality of bolts 52 passing through the clamp seat 5 . Because the sealing rubber ring is arranged in the clamp seat 5, the sealing rubber ring is generally made of rubber or polytetrafluoroethylene, so that its connection with the housing is in a sealed state.

[0021] A housing 1 has an intermediate cavity. One end of the housing 1 is fixed on the clamp seat 5 by bolts, and the other end is provi...

Abstract

A changing valve device with pressure is used for unloading an old valve on a pressure vessel adapter and replacing a new valve, comprising a clamp seat clamped on the pressure vessel adapter; a hollow housing, between one end of the hollow housing and the clamp seat is provided with a sealing rubber ring and is sealing connection, the other end is provided with a through-hole for a unloading valve stem exserting, the housing side surface is closed to the end portion of the clamp seat and is protruding provided with containing cavities; a unloading valve stem which is hollow tubular, one end of the unloading valve stem is provided with a through-groove whose width is greater than that of the wideest part of the valve, a rotatable spindle sleeve is arranged in the housing and seal connected with the housing, the other end of the unloading valve stem is a rotation end which exserts to the external of the housing; and a loading valve stem which sleeves in the unloading valve stem and is sealing connected with the housing, the centers of the loading valve stem, the unloading valve stem, and the housing is on the same axis.

Description

technical field [0001] The invention relates to a valve changer, in particular to a valve changer for removing and replacing a pressure vessel valve under pressure. Background technique [0002] For pressure vessels containing dangerous gases, the valve needs to be replaced in time after the valve is damaged. For example, the service life of liquid chlorine steel cylinders used for filling, transporting and storing liquid chlorine is generally 12 years, and the service life of chlorine cylinder valves is generally 6 years, especially when the valves of chlorine cylinders are damaged, they need to be replaced in time. Since the chlorine bottle is not allowed to be completely emptied during use, it is necessary to replace the valve of the chlorine bottle under pressure. [0003] In the past, the chlorine cylinder valve was replaced by transporting the chlorine cylinder to an open area in the suburbs. The operator put on a gas mask, loosened the chlorine cylinder valve with a ...
