Embodiment 1

[0041] Throttle stop valve, with cut-off and throttling functions, can reduce production costs, increase production efficiency, and improve quality, such as figure 1 , figure 2 , image 3 As shown, specifically set to the following structure:

[0042] Including a commonly used stop valve, the stop valve includes a stop valve body 1, the stop valve body has three through holes communicating with each other, the three through holes have three ports, one port is used to connect with the connecting pipe 2, and one port Plastic screw 6 is worn when not in use, and a port is worn with copper nut 7 when not in use. There is a shut-off valve seat in the shut-off valve main body 1, and a shut-off valve spool is installed in the shut-off valve main body 1 and at the shut-off valve seat, and a connecting pipe 2 is threadedly connected to a port of the shut-off valve main body 1. 2 is L-shaped as a whole, and a throttling structure is installed in the connecting pipe 2, and the thrott...

Embodiment 2

[0047] This embodiment is further optimized on the basis of the above-mentioned embodiments, further to better realize the present invention, especially adopt the following configuration structure:

[0048] The throttling stop valve also includes a filter structure installed in the straight pipe 2b, and the filter structure is located upstream of the throttling structure, and the refrigerant first passes through the filter structure and then passes through the throttling structure. The filter structure is used to filter the impurities that exist or may exist in the refrigerant, purify the circulating refrigerant, and avoid the impact of impurities on the structural components of the circulation system.

[0049] Specifically, the filter structure is a filter screen 5 with a narrow top and a wide bottom. The beginning of the filter screen 5 is a filter surface, and the filter surface is surrounded by a conical surface. The end of the filter screen 5 is a cylindrical section. On ...

Embodiment 3

[0052] On the basis of the above embodiments, this embodiment also provides an air conditioner with a throttle cut-off valve, including the throttle cut-off valve in Embodiment 2. It plays the role of throttling and filtering, and the quite throttling and pressure-reducing filter device is integrated with the stop valve, which can cancel other throttling devices of the air conditioner, reduce costs and procedures, and improve quality. The connecting pipe of the throttle stop valve is installed on a refrigerant discharge port of the air conditioner. The air conditioner adopting the throttling stop valve is more convenient in installation, maintenance and replacement, has lower production and maintenance costs, and does not occupy too much installation space. It has the functions of cut-off and throttling, and can reduce the throttling valve set separately, which is convenient for production assembly and maintenance and replacement, reduces production cost, and improves producti...

Abstract

The invention provides a throttling stop valve and an air conditioner with the throttling stop valve, and relates to the technical field of air conditioner valves. The problem that a top valve for theair conditioner does not have the throttling function is solved. The throttling stop valve comprises a stop valve body internally provided with a stop valve element and a connecting pipe connected with the stop valve body, a throttling structure is arranged in the connecting pipe, the throttling structure is arranged at the connecting pipe, it can be ensured that the structure of the throttling stop valve is not too compact, mounting and maintaining are convenient, space occupied by mounting can be saved, the air conditioner comprises the throttling stop valve, mounting space is saved while mounting is facilitated, production efficiency is improved, and production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of air-conditioning valves, in particular to a throttle stop valve and an air conditioner with the throttle stop valve. Background technique [0002] With the continuous improvement of people's living standards in our country and the improvement of the quality of life requirements, the demand for household air conditioners in the home appliance market is increasing. This trend can also greatly help improve the company's economic benefits. In such a good environment, In the case of mass production of products, the company needs to improve all aspects of the company to achieve the purpose of minimizing costs and maximizing benefits. Therefore, it is necessary to conduct research on issues such as cost efficiency and quality of air-conditioning production, in order to increase sales in this favorable environment. , increase turnover. [0003] The cut-off valve used in the existing air conditioner does not have...
