The chip ball valve consists of a valve body, a ball, a gland, a handle, an adjusting sleeve and a leaf spring. It is characterized by a ball hole on the ball, a lower shaft and an upper shaft on the ball, and the ball is fixed by a bearing, a gland and a screw In the valve body, the upper shaft is fitted with a sealing ring and a buckle cover is provided with a positioning block, the end of the upper shaft is equipped with a handle, and the valve body on both sides of the sphere is sequentially installed with a valve seat sealing ring, a leaf spring and an adjusting sleeve.
The reasons for the increased pulsation of the chip ball valve are described as follows:
Choosing a suitable expansion valve with a large capacity of the chip ball valve will increase the pulsation; change the superheat of the chip ball valve. When the degree of superheat is small, it is easy to increase the number and intensity of the pulsation; choose an appropriate injection form, the cross-injected chip ball valve has the characteristics of preventing pulsation, and increases the convective heat transfer coefficient of the evaporator. Shortens the refrigerant circulation pipeline; Choose a suction pipe with an appropriate diameter; modify the installation position and method of the temperature sensor; select a suitable outlet position of the outer balance pipe; appropriately reduce the flow rate of the refrigerant in the evaporator; appropriately change the heat capacity of the heat sensor itself to have pulsation damping Effect.
