Abstract

The invention discloses a valve with an anti-freezing function, and relates to the technical field of valve devices. The valve aims to improve the effect of automatic heating control. The valve specifically comprises a valve body installed on a conveying pipe, wherein an electric heating wire assembly is installed on the outer wall of the valve body in an embedded mode, the electric heating wire assembly comprises a first electric heating wire installed on the surface of the valve body and a second electric heating wire installed at the rotating position of a valve rod in the valve body, a control mechanism for controlling the first electric heating wire and the second electric heating wire to work is installed on the conveying pipe, and two limiting rings are integrally arranged on the circumferential outer wall of the conveying pipe. According to the valve, an air bag, a conductive strip, a conductive sheet and other structures are arranged, the capacity of thermal expansion and coldcontraction of the air bag can be utilized, so that the first electric heating wire and the second electric heating wire work to heat the valve body, moreover, due to the fact that the expansion andcontraction process of the air bag is relatively slow, the phenomenon that the conductive strip and the conductive sheet are repeatedly contacted and separated is avoided, and the working stability ofthe first electric heating wire and the second electric heating wire is guaranteed.

Description

technical field [0001] The invention relates to the technical field of valve devices, in particular to a valve with antifreeze function. Background technique [0002] A valve is a mechanical device that controls the flow rate and flow direction of the flowing fluid medium. The valve is a basic component in the pipeline system; during the pipeline transportation process, the transportation work is controlled through the valve according to the actual needs; due to the influence of the external environment, when When the temperature is too low, the valve may be frozen, which will affect the user's control of the valve; at present, antifreeze valves designed for this problem mostly use heating to prevent freezing, although a certain antifreezing effect has been achieved, but , the work of the heating mechanism cannot be controlled by itself according to the temperature, continuous heating leads to high energy consumption, and the antifreeze effect of intermittent heating cannot ...
