The use of fan safety valve Fan safety valve is used to protect the safety of fans and equipment, and the pressure in the fan and equipment abnormal increase to a certain value (safety valve opening pressure), the safety valve can automatically open and discharge the media, To prevent the pressure continues to rise, when the fan and the pressure in the device down to a certain value (relief valve relief valve pressure), the safety valve automatically shut down. Fan safety valve compared with the traditional safety valve, has the following characteristics: 1, the fan is mainly used for low-pressure air medium, so the fan relief valve to eliminate the export of exhaust flange, and the use of small holes around the valve body directly discharge medium, at the same time The spring cavity is directly set on the back of the valve flap. With the patented structure, the valve structure is more compact and media discharge is more smooth, while the weight of the valve is only 1/3 to 1/5 of the traditional safety valve. 2, the fan valve in the valve and valve seat with a pressure accumulation tank patented structural design, and the use of conventional safety valve adjustment ring and set as a screw structure, the structure is more simple, the use of the valve is also more convenient, and Valve performance is more stable. 3, the minimum opening pressure of the traditional safety valve is generally 0.1MPa, while the safety valve for the fan, the opening pressure is often required to be less than 0.1MPa, the traditional safety valve to use less rigid spring, at low pressure can not be accurate Sensitive action. The design of the fan safety valve opening pressure range of 0.02 ~ 0.2MPa, the fan valve in the low pressure can be very accurate and sensitive action. 4, the fan valve spring force through the valve stem on the role of the valve and the valve sealing surface is very close to the role of the traditional safety valve away from the valve seal plane, therefore, compared with the traditional safety valve, Fan safety valve performance more stable and reliable. 5, the traditional safety valve through the outlet channel to discharge medium in one direction, so the media easily lead to system vibration emissions, and fan safety valve through the valve body evenly distributed around the hole to the surrounding uniform discharge of media, so the valve moves smoothly No vibration. 6, the fan valve does not adjust the ring, the use of very simple, safety valve factory has been opened by the user's request pressure debugging, the user directly to the safety valve installed on the system can be used.
