Embodiment 1

[0017] Embodiment 1, referring to Figures 1, 2, and 3, the valve body 4 is processed, and the electrode cover 2, the valve body sealing plate 9 and the valve body 4 are welded together to ensure complete sealing. On both sides of the valve body 4 A valve port 5 is set up. The valve port 5 is made of ceramic or wear-resistant cast iron. The valve port 5 is connected to the inlet and outlet assembly 6. A two-way valve plate assembly 10 is installed at the bottom of the valve body 4. The two-way valve plate assembly 10 consists of the valve plate 7, The elastic connecting piece 14 and the valve plate connecting piece 8 are composed. The valve plate 7 is made of two pieces of ceramic or wear-resistant cast iron. , to separate the two valve plates 7, the elastic connector 14 can be one or more than one, springs can be used, and other elastic materials can also be used. The bottom surface and two sides formed by the two valve plates 7 are fixed on the valve plate In the groove of th...

Abstract

The bi-directional electronic expansion valve includes step motor and valve body. On and below the valve body, there are welded electrode sealing cover and valve body sealing plate. The step motor is set inside the electrode sealing cover on the valve body, and the electrodes set on the electrode sealing cover are connected to the step motor. The valve body has valve ports connected to liquid inlet and outer assembly on its two sides. The present invention features that the bi-directional valve plate assembly inside the bottom of valve body comprises valve plate, elastic connecting part and valve plate connecting part; and the step motor is connected via lead screw and driving assembly to the bi-directional valve plate assembly. The bi-directional electronic expansion valve has bi-directional control, less pressure loss, simple structure, high control precision and other advantages.

Description

Technical field: [0001] The invention relates to the technical field of the refrigeration and air conditioning industry, and is a throttling component used in the refrigeration and air conditioning industry, in particular to a fully enclosed two-way electronic expansion valve. Background technique: [0002] Although the main composition of the refrigeration and air conditioning system (HVAC) has not changed for many years, improving the efficiency, reliability, automation level and reducing system energy consumption of the system are still the development direction of the continuous improvement of the refrigeration system. As a throttling component, thermal expansion valve has been widely used in the refrigeration and air-conditioning industry, but its control accuracy is low, the response speed is slow, the adjustment range is narrow, the degree of superheat cannot be adjusted, the versatility of different refrigerants is poor, and it is prone to leakage and failure rate Hi...
