Single-seat vacuum self-standing type adjusting valve

Abstract

The invention discloses a single-seat vacuum self-standing type adjusting valve. The single-seat vacuum self-standing type adjusting valve comprises an adjusting valve main body, a connection mechanism in the middle of the adjusting valve main body and a fixing mechanism at the bottom end of the adjusting valve main body, wherein the connection mechanism comprises a first fixed ring and a second fixed ring; a valve element is arranged at the bottom end of the adjusting valve main body; the first fixed ring is arranged at the top end of the valve element; an adjusting block is arranged in the middle of the adjusting valve main body; the second fixed ring is arranged at the bottom end of the adjusting block; fixed columns are arranged at two sides of the top end of the first fixed ring; thefirst fixed ring is internally provided with an inner thread; the fixed columns and a rotary groove are arranged, so that the cumbersomeness and complexity in a connection and fixing process of the adjusting valve are effectively reduced; the fixed columns only need to be aligned to the rotary groove to be connected and fixed, so that the time is saved and the utilization of special tools is reduced; in a mounting process, scratches and damages to the adjusting valve in a mounting process are reduced, the service life of the adjusting valve is prolonged and the loss of devices is reduced.

Description

technical field

[0001] The invention belongs to the technical field of regulating valves, in particular to a single-seat vacuum self-supporting regulating valve. Background technique

[0002] Regulating valve, also known as control valve, accepts the control signal output by the regulating control unit and uses power operation to change the final control element of process parameters such as medium flow, pressure, temperature and liquid level. In order to make the regulating valve more stable, it is more convenient to use. Convenience, a single-seat vacuum self-supporting regulating valve came out along with the trend.

[0003] There are certain problems in the use of existing control valves. The connection and fixing of the control valve is very cumbersome and complicated. Since the control valve is usually fixed with the flange when connecting, it not only wastes time, but also requires the use of professional tools. It is easy to scratch and damage the regulating valve d...
