Controlled heating valve

Abstract

The invention discloses a controlled heating valve. The controlled heating valve comprises a valve body, wherein a bearing seat is fixedly mounted on the valve body; a temperature sensor is put on thetop of the bearing seat; a movable slot is formed in the top part of the bearing seat; a movable plate is mounted in the movable slot in a sliding manner; the top part of the movable plate extends tothe upper part of the bearing seat; the movable plate is matched with the temperature sensor; a mounting groove is formed in a side inner wall of the movable slot; a rotating shaft is mounted in themounting slot in a rotating manner; a rotating plate is fixedly mounted on the rotating shaft and is matched with the movable plate; a gear is fixedly mounted on the rotating shaft; a telescopic motoris fixedly mounted on a top inner wall of the mounting groove; a rack is mounted on an output shaft of the telescopic motor and is engaged with the gear; a fixed groove is formed in the top part of the bearing seat; and a fixture block is fixedly mounted on a side inner wall, away from the movable plate, of the fixed groove. According to the controlled heating valve disclosed by the invention, the temperature sensor is conveniently mounted and fixed, so that the time and the labor are reduced, a structure is simple, and the using is convenient.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a controllable heating valve. Background technique [0002] The working medium (such as sulfur) that cannot flow at low temperature in winter is generally installed with electric heat tracing to heat the liquid to make it flow. Because the electric heat tracing cannot be in uniform contact with the valve, the working medium flowing in the valve will deteriorate due to local overheating. Or some parts cannot be heated and the liquid cannot flow, resulting in blockage and interruption of system operation, which brings great inconvenience to the work of working medium transportation and maintenance. Later, people installed temperature sensors and heating plates on the valves. Control to alleviate the problem of uneven heating. In the prior art, the temperature sensor is not easy to install, and the installation is time-consuming and labor-intensive. Therefore, we have proposed a cont...

[0002] The working medium (such as sulfur) that cannot flow at low temperature in winter is generally installed with electric heat tracing to heat the liquid to make it flow. Because the electric heat tracing cannot be in uniform contact with the valve, the working medium flowing in the valve will deteriorate due to local overheating. Or some parts cannot be heated and the liquid cannot flow, resulting in blockage and interruption of system operation, which brings great inconvenience to the work of working medium transportation and maintenance. Later, people installed temperature sensors and heating plates on the valves. Control to alleviate the problem of uneven heating. In the prior art, the temperature sensor is not easy to install, and it is time-consuming and labor-intensive to install. Therefore, we have proposed a controllable heating valve to solve the above problems.
