Description

Special valve suitable for extreme environment Technical Field The utility model relates to the technical field of valves, in particular to a special valve suitable for extreme environments. Background The antifreezing valve is a special valve which is commonly applicable to extreme environments at present, and the main reason is that the special design and the function of the antifreezing valve can effectively cope with severe conditions such as low temperature, icing and the like. The valve is usually made of low-temperature-resistant materials, and is provided with a heating device or a heat-insulating layer to prevent the medium from freezing, so that the valve can be normally opened and closed and sealed in extremely cold environments. At present, china patent discloses an antifreezing tap water valve (CN 221800781U), and the antifreezing tap water valve is convenient for heating water in the small water tank to a customized temperature by adopting the cooperation of the small water tank, a temperature controller, an electric water heating rod and a mounting ring, and is convenient for extracting hot water in the small water tank and circularly flowing into the heat preservation cover by adopting the cooperation of a first conduit, a small water pump, a second conduit, a heat preservation cover, a metal heat conduction ring and a drain pipe, and simultaneously transmits heat to a valve body by the metal heat conduction ring, so that the valve body is convenient to heat, and the situation that the valve body is frozen can be prevented. Because current equipment is through setting up heating cycle structure and realizing heat conduction in the heat preservation cover outside, but when the operation under severe cold environment, the heating medium is easy to take place the heat loss when flowing through pipe and drain pipe, leads to the actual heating heat preservation effect to the valve to descend to influence whole practicality. Disclosure of utility model Based on the above, it is necessary to provide a special valve suitable for extreme environments, aiming at the problems of poor heating effect and low practicability of the existing antifreezing valve. The special valve suitable for the extreme environment comprises a manual adjusting valve and a heating and heat-preserving mechanism, wherein the heating and heat-preserving mechanism comprises two semicircular sheaths, the two semicircular sheaths are respectively attached to two opposite surfaces of the manual adjusting valve, the two semicircular sheaths jointly form a cylinder, a heat conducting cavity is formed in the semicircular sheaths, an electric heating wire is embedded in the heat conducting cavity, and an antifreezing heat conducting medium in contact with the electric heating wire is filled in the heat conducting cavity. In one embodiment, the heating wire is arranged in the heat conduction cavity, and the local cross section shape of the heating wire is serpentine. In one embodiment, a temperature controller electrically connected with the heating wire is fixedly connected to the outer side of the semicircular sheath, and the detection end of the temperature controller penetrates through the heat conducting cavity. In one embodiment, a switching power supply is fixedly connected to the outer side of one of the semicircular sheaths, and the heating wire and the temperature controller are electrically connected with the switching power supply through wires. In one embodiment, the inner side of the semicircular sheath is provided with a silicone rubber-based heat conduction pad, and the inner side of the silicone rubber-based heat conduction pad is in contact with the manual regulating valve. In one embodiment, the upper surface of the semicircular sheath is fixedly connected with a mounting sleeve, a bolt is inserted into the inner side of one mounting sleeve, the rod portion of the bolt penetrates through one mounting sleeve and extends to the outer portion of the other mounting sleeve, and a nut in contact with the other mounting sleeve is connected with the rod portion of the bolt in a threaded mode. In one embodiment, a hinge is fixedly connected to the lower surface of one of the semicircular sheaths, and one end of the hinge is fixedly connected with the other semicircular sheath. Advantageous effects The special valve suitable for the extreme environment is characterized in that the heating and heat-preserving mechanism dynamically adjusts the temperature of alkylbenzene type heat conduction oil in the heat conduction cavity, and efficiently transfers heat to key parts of the valve body at extremely low temperature.
