Abstract

The invention discloses a high-temperature and high-pressure safety valve and belongs to the technical field of safety valves. Existing high-temperature and high-pressure safety valves bear low temperatures and are relatively low in precision and poor in reliability. The high-temperature and high-pressure safety valve comprises a valve body, a valve deck, a valve element, springs, a guide sleeve, a sealing ring, a heat-insulation pad, an adjustment rod and a locking nut, wherein the valve body and the valve deck are connected through a flange. A safety protection function in a pressure system is achieved, and risks caused by overpressure of the system are prevented. The high-temperature and high-pressure safety valve is simple in structure, fast to assemble, flexible in action and high in control precision and can be widely applied to the high-temperature and high-pressure system. According to the high-temperature and high-pressure safety valve, the safety protection function in the pressure system is achieved, and the reliability is high.

Description

technical field [0001] The invention belongs to the technical field of safety valves, in particular to a high-temperature and high-pressure safety valve, which is suitable for safety protection in high-temperature and high-pressure gas delivery pipeline systems. Background technique [0002] With the development of high temperature and high pressure systems, relevant safety protection measures are very important. As an important protection device of the system, safety valves have been widely used in high temperature and high pressure systems. The current high-temperature and high-pressure safety valves withstand low temperatures, relatively low precision, and poor reliability. Such traditional high-temperature and high-pressure safety valves often have unfavorable factors such as tremors, frequency jumps, low reseating pressure, and low control accuracy, resulting in waste of energy. Contents of the invention [0003] Aiming at the problems existing in the prior art, this...
