Problems solved by technology

When the temperature to be controlled is the liquid inside the pressure vessel, the temperature bulb must be placed inside the vessel. It is necessary to open a hole in the pressure vessel, and the capillary must pass through the hole. Due to the high pressure in the pressure vessel, the seal between the capillary and the hole is not good. If it is good, it will cause leakage of the pressure vessel, and it is impossible to ensure sufficient pressure inside the vessel

Abstract

The invention discloses a water seal protection sleeve of a remote-transmission temperature sensing bulb. The water seal protection sleeve comprises a heat conduction pipe (1), a threaded connector (2), a pressing screw plug (6) and the temperature sensing bulb. One end of the heat conduction pipe (1) is sealed, and the other end of the heat conduction pipe (1) is connected with the threaded connector (2). The main end of the temperature sensing bulb is inserted into the heat conduction pipe (1), and the capillary tube end of the temperature sensing bulb is located in the threaded connector (2). The capillary tube end in the threaded connector (2) is provided with a U-shaped card (3) and an expansion sleeve (4) in sequence from interior to exterior, and the expansion sleeve (4) is axially provided with a one-edge notch corresponding to the capillary tube end. The pressing screw nut (6) presses an elastic washer (5) into the threaded connector (2). According to the water seal protection sleeve of the remote-transmission temperature sensing bulb, the temperature sensing bulb is arranged in the water seal protection sleeve, heat is transmitted to the temperature sensing bulb through the water seal protection sleeve, the function of automatically controlling temperature is achieved, in addition, the water seal protection sleeve is in threaded connection with a pressure container, the high enough sealing performance can be kept.

Description

technical field [0001] The invention relates to a water-sealed sheath of a remote sensing temperature bulb. Background technique [0002] As we all know, the pressure-type thermostat converts the change of the controlled temperature into a change of space pressure or volume through a closed temperature bulb and capillary tube filled with a temperature-sensing working medium. The instantaneous mechanism automatically closes the contact to achieve the purpose of automatic temperature control. When the temperature to be controlled is the liquid inside the pressure vessel, the temperature bulb must be placed inside the vessel. It is necessary to open a hole in the pressure vessel, and the capillary must pass through the hole. Due to the high pressure in the pressure vessel, the seal between the capillary and the hole is not good. Well, it can cause leakage of the pressure vessel, and sufficient pressure inside the vessel cannot be guaranteed. Contents of the invention [000...
