example 1

[0028] figure 1 It is a longitudinal sectional view conceptually showing an example of a multifunctional operation valve having the valve structure described in the present invention.

[0029] The internal structure of the multi-function operating valve 10 adopts the valve structure 3, which is the core of the present invention. Since it has the functions of the expansion valve 5 and the auxiliary valve 6, it is used for the connection between the indoor unit and the outdoor unit in the air conditioner with the refrigeration cycle. Piping.

[0030] In the valve structure 3, the centers of the two valve bodies 1, 1' are aligned with each other and are arranged opposite to each other, and the valve seats 2, 2' corresponding to these valve bodies are integrally constructed. This is exactly the technical idea of ​​the invention.

[0031] Here, in order to use this integrated product as a valve, these valve bodies 1, 1' and valve seats 2, 2' must be connected and used on the pip...

[0044] figure 2 It is a longitudinal sectional view conceptually showing another example of a multifunctional operating valve having the valve structure described in the present invention.

[0045] The multifunctional operation valve 10B is figure 1 Compared with the multi-function operation valve 10, the difference is that the expansion valve 5B is a concrete manifestation of the stepless adjustment of the refrigerant flow rate through the stepless reciprocating sliding of the valve body 1 through the rotational driving force of the motor.

[0046] The expansion valve 5B includes a coil 8a that generates a rotating magnetic field, a rotor 8b that rotates by the rotating magnetic field, a female screw cylinder 8c that has a built-in female thread and is fixed to the rotor 8b and rotates synchronously, and is fixed to the valve seat 2 , without rotary motion, insert the valve body 1, the male thread barrel 8d of the male thread corresponding to the female thread of the exter...

example 3

[0050] image 3 It is a piping diagram of an air conditioner using the multifunctional operation valve of the present invention.

[0051] The air conditioner 50 is equipped with the outdoor unit 20 and the indoor unit 30, and its various parts (the heat exchanger 13, the four-way switching valve 12, the compressor 11, the gas assist valve 14, the heat exchanger 21) are the same as those of the current air conditioner 150. (The heat exchanger 113, the four-way switching valve 112, the compressor 111, the gas assist valve 114, and the heat exchanger 121) are the same. The difference is that the current expansion valve 106 and the liquid auxiliary valve 105 are integrated to form the multifunctional operation valve 10 .

[0052] According to this figure, the effects of the multifunctional operation valve 10 with the valve structure of the present invention have been explained, namely, coaxial processing is realized, the processing process is simplified, the connection by welding...

Abstract

The invention provides a valve structure of simple, saving space and low-cost, comprising two opposite valve bodies with consistent centers and two integrated valve seats. Because the centers of the two valve bodies are consistent and they are oppositely arranged, and the two valve seats are of an integrated structure, it saves the space by omitting intermediate tubing, reduces the manufacturing process by integration, realizes the simplification by simplifying the structure of the valve, eliminating the leakage by omitting welding points.

Description

technical field [0001] The present invention relates to a valve structure suitable for a dedicated valve for piping, and a multifunctional operating valve having such a valve structure, invented for connecting valves having different functions such as piping between an indoor unit and an outdoor unit of an air conditioner having a refrigeration cycle. Background technique [0002] The piping between the indoor unit and the outdoor unit of the air conditioner having a refrigeration cycle is connected to an auxiliary valve that shuts off the piping between the indoor and outdoor units, and an expansion valve that adjusts the flow rate of refrigerant in the piping. Figure 4 This is the piping diagram of the current air-conditioning equipment, taken from Japanese Patent Laid-Open No. 7-167534 ( figure 1 , Figure 5) in the example diagram (Figure 5 of the publication). [0003] The air conditioner 150 connects the outdoor unit 120 and the indoor unit 130 through pipes to form a...
