Description

Novel electronic expansion valve body assembly Technical Field The utility model relates to the technical field of expansion valves, in particular to a novel electronic expansion valve body assembly. Background In a refrigeration system, an electronic expansion valve is used as a key component, and the sealing performance of the electronic expansion valve is directly related to whether the refrigerant leaks or not, so that the overall efficiency and the safety of the refrigeration system are affected. At present, a common integrated electronic expansion valve body assembly adopts a valve core sleeve, a fixed sleeve and a valve body to be integrally formed or simply fixed, a sealing structure only depends on a small amount of sealing rings, so that the connection between parts is not tight enough, the sealing requirement under severe working conditions is difficult to meet, and the phenomenon of refrigerant leakage occurs. In addition, because the inside guide holder of valve body subassembly, guide plate and parts such as case cover are difficult to dismantle after the equipment, when the damage appears in the electronic expansion valve, maintenance personnel can't take out the inside parts conveniently and maintain and change, often need whole change, not only cause the wasting of resources, also greatly increased use cost, severely restricted the life of electronic expansion valve. Therefore, developing an electronic expansion valve body assembly with excellent sealing performance and convenient maintenance is a problem to be solved urgently in the industry. Disclosure of utility model The utility model aims to at least solve one of the technical problems in the prior art, and provides a novel electronic expansion valve body assembly, wherein a valve core sleeve and a fixed sleeve can be installed on a valve body in a threaded connection mode, and a guide plate is extruded in the installation process, so that a guide seat is tightly attached to a sealing ring arranged in the valve body and the valve body, the tightness of the valve body is improved, three groups of sealing rings are arranged, all parts installed on the valve body are tightly connected, the sealing performance of the device is further improved, the condition of refrigerant leakage is prevented, and the guide seat, the guide plate and the valve core sleeve which are installed in the valve body can be quickly assembled and disassembled, all parts in the valve body can be taken out for maintenance and replacement, the condition that the existing integrated electronic expansion valve is difficult to maintain after being damaged is avoided, and the service life of the electronic expansion valve is prolonged. The utility model also provides a novel electronic expansion valve body assembly, which comprises a valve body, wherein the lower bottom wall of the valve body is fixedly connected with a guide seat, the side surface of the guide seat is fixedly connected with a first sealing ring, the upper surface of the guide seat is fixedly connected with a guide plate, the upper surface of the guide plate is adhered with a valve core sleeve, the side surface of the valve core sleeve is fixedly connected with a second sealing ring, the side surface of the valve core sleeve is movably connected with a fixed sleeve, and the side surface of the fixed sleeve is fixedly connected with a third sealing ring; The valve core is characterized in that a stator coil is arranged on the side surface of the valve core sleeve, a valve core rod is connected with the side inner wall of the valve core sleeve in a threaded mode, a positioning spring is fixedly connected with the lower surface of the valve core rod, a supporting spring is fixedly connected with the upper surface of the valve core rod, and a valve core end is fixedly connected with one end, away from the valve core rod, of the supporting spring. Through above parts, can be with parts such as guide holder, guide plate and case cover fast assembly on the valve body to all set up the sealing washer at the junction of each part, improved holistic leakproofness of each part and electronic expansion valve, can demolish each part after the use simultaneously and change and maintain, improved the life of expansion valve. According to the novel electronic expansion valve body assembly, the side surface of the guide plate is fixedly connected with the positioning block, and the side surface of the positioning block is fixedly connected with the valve body.
