Problems solved by technology

[0004] However, the refrigerant on the outlet side of the evaporator is constantly changing due to the environment, pressure and temperature. The power head will perceive it as a temperature change and continuously apply force to the push rod, so that the push rod frequently pushes the valve core to move to adjust the valve hole. opening, which causes the push rod to vibrate

Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0033] see figure 1 , figure 2 , figure 1 A schematic cross-sectional view of a thermal expansion valve 100 is shown, figure 2 for figure 1 A partial enlargement of the . The thermal expansion valve 100 includes a valve body 1 , a push rod 2 , a valve core 3 , an adjustment mechanism 4 and a power head 5 . For the convenience of description, the upper end of the valve body 1 in the illustration is called the top, and the lower end is called the bottom; the length direction of the valve body 1 is called the longitudinal direction, which is parallel to and perpendicular to the paper surface The direction of the lengthwise direction of the valve body 1 is referred to as the transverse direction.

[0034] The power head 5 is fixed on the top of the valve body 1, the adjustment mechanism 4 is fixed on the bottom of the valve body 1, the push...

Abstract

The invention discloses a heating power expansion valve. The heating power expansion valve comprises a valve body and a power head, the valve body is provided with a first channel and a second channel, wherein a liquid phase refrigerant introduced into an evaporator passes through the first channel, a gas phase refrigerant introduced from the evaporator to a compressor passes through the second channel, the valve body further comprises a mounting hole, the mounting hole at least comprises a mounting hole side wall and is located on the upper part of the second channel, the mounting hole communicates with the second channel, at least part of the power head is located in the mounting hole, the mounting hole is further provided with a heat insulation blocking part delaying response time of the expansion valve, and the mounting hole is separate from the second channel through the heat insulation blocking part. According to the heating power expansion valve, the heat insulation blocking part is arranged in the mounting hole, response time of the expansion valve is delayed, and phenomenon of air conditioner pressure vibration is inhibited.

Description

technical field [0001] The invention relates to the field of throttling control, in particular to a thermal expansion valve and a refrigeration system with the thermal expansion valve. Background technique [0002] In the refrigeration cycle of the air conditioner, there are generally compressors, condensers, liquid receivers, expansion valves and evaporators. 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. [0003] In the existing thermal expansion valve, the power head senses the temperature and pressure of the refrigerant at the outlet side of the evaporator to open and close the valve hole, and...
