Problems solved by technology

[0004] As the components of the expansion valve tend to be miniaturized, the miniaturization of the air box head is also an inevitable development trend. However, simply reducing the diameter of the diaphragm will affect the lift of the diaphragm to a certain extent, so that it is difficult to control the flow stably

Abstract

The invention discloses a thermal expansion valve, which includes an air box head, the air box head includes an air box seat, an air box cover, and a diaphragm, the air box cover and the air box seat are fixedly arranged; the diaphragm is located between the air box cover and the air box seat Between, the diaphragm includes a first concave portion and a wave portion, the first concave portion is located in the middle of the diaphragm, the wave portion is located outside the first concave portion, and the concave direction of the first concave portion is relatively away from the air box cover. Through the setting of the present invention, without reducing the filling amount, the circumferential diameter of the diaphragm is relatively reduced, which is beneficial to the miniaturization of the air box head, and through the setting of the first concave part and the wave part, it is helpful to make the The performance of the thermal expansion valve is relatively stable.

Description

technical field [0001] The present invention relates to the field of fluid control. Background technique [0002] The thermal expansion valve is a throttling component commonly used in air-conditioning and refrigeration equipment. It can throttle and reduce the pressure of the liquid refrigerant from the condenser, and adjust the refrigerant sent from the condenser to the evaporator according to the temperature at the outlet of the evaporator. The flow rate of the agent can be adjusted to meet the changing needs of the refrigeration load. The general principle of the thermal expansion valve to control the flow of refrigerant is: the temperature of the outlet of the evaporator is sensed by the gas box head, and the medium in the gas box head generates a corresponding degree of thermal expansion according to the temperature sensed by the gas box head, and the thermal expansion is used to balance the temperature of the gas. The valve stem connected to the box head generates pr...
