Valve with high safety performance and anti-freezing function

Abstract

The invention discloses a valve with the high safety performance and the anti-freezing function. The valve comprises a valve body, a sealing cover plate is arranged at the top end of the valve body, avalve element is arranged in the valve body, a rotating shaft is arranged at the top end of the valve element, a filter screen is arranged in the valve element, a waterproof fan is arranged in the filter screen, and a first threaded connector is arranged at one end of the valve body. A second threaded connector is arranged at the other end of the valve body, a first heating sleeve is arranged onthe inner side wall of the first threaded connector, a second heating sleeve is arranged on the inner side wall of the second threaded connector, and spiral heating wires are arranged in the first heating sleeve and the second heating sleeve. The valve has the beneficial effects that a handle can be locked when adjustment is not needed, the safety performance of the valve is effectively improved,mistaken opening and mistaken closing are avoided, water flow in the valve can be driven and prevented from being static for a long time, meanwhile, heating can be conducted, the overall anti-freezingperformance of the valve is effectively improved, the use safety of the valve is improved, the service life of the valve is prolonged, and meanwhile, the filtering function is also achieved.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a valve with high safety performance and antifreeze function. Background technique [0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are the control components in the fluid delivery system. They have the functions of cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems range from the simplest cut-off valve to extremely complex There are various types and specifications of valves used in the automatic control system. At present, the existing valves generally do not have the antifreeze function. When the temperature ...

AI Technical Summary

Problems solved by technology

At present, the existing valves generally do not have antifreeze function. When the temperature is low, the valve is frozen and cannot be used normally, causing inconvenience to users and low practicability.
