Anti-freezing adjusting valve

Abstract

The invention discloses an anti-freezing regulating valve, which comprises a pipe body, and a partition block arranged obliquely is installed inside the pipe body, and the partition block is sealed and connected with the inner wall of the pipe body. The two sides of the liquid hole are respectively connected with two rotating rods. The rotating rods on the same side are respectively located at the top and bottom of the partition block. Stirring blades are welded on the side walls all around, the top of the pipe body is connected with a connecting block, the connecting block is a hollow structure, the connecting block and the side wall of the pipe body are threaded with a vertical threaded rod, and the top of the threaded rod is welded with a horizontal The provided rotating handle is provided with an annular slider on the side wall of the threaded rod, and the slider is slidably connected to the inner wall of the connecting block. The invention can promote the flow of liquid in the valve, play the role of heat preservation and heating, and prevent the valve from being frozen in cold weather.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to an antifreeze regulating valve. Background technique [0002] Control valve, also known as control valve, in the field of industrial automation process control, is the final control element that changes the process parameters such as medium flow, pressure, temperature, liquid level, etc. by means of power operation by receiving the control signal output by the adjustment control unit. It is generally composed of actuators and valves. According to the characteristics of the stroke, the regulating valve can be divided into straight stroke and angular stroke; according to the power used by the actuator, it can be divided into three types: pneumatic regulating valve, electric regulating valve and hydraulic regulating valve; according to its function and characteristics There are three types of characteristics: linear characteristic, equal percentage characteristic and parabolic chara...

Problems solved by technology

According to the characteristics of the stroke, the regulating valve can be divided into straight stroke and angular stroke; according to the power used by the actuator, it can be divided into three types: pneumatic regulating valve, electric regulating valve and hydraulic regulating valve; according to its function and characteristics There are three kinds of characteristics: linear characteristic, equal percentage characteristic and parabolic characteristic. The existing regulating valve is easy to be frozen in winter. Therefore, we propose an antifreeze regulating valve
