Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that when the valve seat is welded to the pipeline, the welding fluid will flow into the inner cavity of the valve seat through the end of the valve seat close to the pipeline, so that the welding fluid adheres to the thread on the inner wall of the valve seat, reducing the joint between the valve seat and the pipeline. The tightness of the spool connection

Embodiment 1

refer to image 3 and Figure 4 , The structure of the air-conditioning pipe filling valve body for preventing the backflow of the soldering liquid includes a valve seat 1, a valve core 2 and a flow blocking member 3. In this embodiment, the shapes of the valve seat 1 and the valve core 2 are axially symmetrical, and the valve seat 1 is hollow. The valve core 2 is threadedly connected to the inner wall of the valve seat 1. The inner cavity of the valve seat 1 is provided with first threads 11. All the first threads 11 are arranged along the axial direction of the valve seat 1, and each first thread 11 is along the valve seat 1. The outer wall of the valve core 2 is provided with a second thread 21 matching the first thread 11, all the second threads 21 are arranged along the axial direction of the valve core 2, and each second thread 21 is along the valve core The circumferential distribution of 2, the valve seat 1 and the valve core 2 are connected by the first thread 11 and ...

Embodiment 2

refer to Figure 5 and Image 6, the difference from Embodiment 1 is: in this embodiment, at least one groove 12 for blocking the solder liquid is provided on the valve seat 1, and in this embodiment, a groove 12 is provided, and the shape of the groove 12 is set It is an annular groove, the groove 12 is arranged in communication with the inner cavity of the valve seat 1, and the groove 12 is arranged coaxially with the valve seat 1, which reduces the interference with the valve core 2 during installation, thereby facilitating the connection between the valve core 2 and the valve seat 1. To improve the tightness of the connection between the valve core 2 and the valve seat 1, in other embodiments, multiple grooves 12 can be provided, and the number of grooves 12 can be determined according to the amount of welding liquid, and all grooves 12 that can block the welding liquid can be used. .

[0039] refer to Figure 5 and Image 6 , the groove 12 includes a blocking section 1...

Embodiment 3

refer to Figure 7 and Figure 8 , the difference from Embodiment 1 is: in this embodiment, the blocking member 3 includes at least one extending section 31 and at least one blocking section 121 , and in this embodiment, one extending section 31 and one blocking section 121 are provided. In the example, any combination of a plurality of extension sections 31 and a plurality of blocking sections 121 can be used, which can be used to block the flow of the welding liquid. The flow section 121 is welded to the side of the extension section 31 close to the valve core 2, and the side of the blocking section 121 close to the valve core 2 is flush with the inner wall of the valve seat 1, which reduces the impact of the blocking section 121 on the connection between the valve seat 1 and the valve core 2. influence, thereby reducing the possibility of the valve core 2 interfering with the choke section 121, ensuring the integrity of the valve core 2, thereby improving the sealing perfor...

Abstract

The invention discloses an air conditioner pipe filling valve body structure capable of preventing welding fluid from flowing backwards, and particularly relates to the technical field of air conditioner pipeline machining, the air conditioner pipe filling valve body structure comprises a valve seat and a valve core, the valve seat is hollow, the valve core is in threaded connection with the inner wall of the valve seat, and the air conditioner pipe filling valve body structure further comprises a flow blocking piece used for preventing the welding fluid from flowing backwards. The flow blocking piece is located at the end, close to a pipeline, of the valve seat, and the flow blocking piece is fixedly connected with the valve seat. According to the air conditioner pipe filling valve body structure capable of preventing the welding fluid from flowing back, through the flow blocking piece, the welding fluid permeating into the inner cavity of the valve seat can be conveniently blocked, the length of a welding fluid flowing path is shortened, then the welding fluid is prevented from being attached to threads on the inner wall of the valve seat, and the connecting tightness of the valve seat and the valve element is improved.

Description

technical field [0001] The invention relates to the technical field of air-conditioning pipeline processing, in particular to an air-conditioning pipeline filling valve body structure for preventing the backflow of welding liquid. Background technique [0002] With the increase in the number of cars, people pay more attention to the comfort of the car, and the effect of the air conditioner in the car is also a part of people's evaluation of the comfort of the car; the pipeline of the car air conditioner usually needs to be filled with refrigerant, and then the inlet and outlet of the pipeline are adjusted through the filling valve. Blocking. [0003] In the related art, the filling valve includes a valve seat and a valve core. First, the valve seat and the pipeline are welded, and then the valve core and the inner wall of the valve seat are threadedly connected to realize the plugging of the pipeline. [0004] In view of the above-mentioned related technologies, the invento...
