Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Please refer to FIGS. 1-5 , the present utility model provides a technical solution: a solenoid valve exhaust valve seat. In this solution, it mainly solves the problem that the size of the traditional solenoid valve exhaust valve seat is fixed and needs to be customized according to the usage conditions during use. In the scheme, the valve seat unit 1 of the same size is designed. There are two channels 2 on the valve seat unit 1. The channel 2 is used for intake and exhaust. The valve seat unit 1 is made of aluminum alloy as a whole. The outer sides of the seat unit 1 are rounded by the seat, which is convenient for installation, and at the same time avoids unnecessary scratches caused by the edges and corners of the valve seat unit 1 during installation. There are multiple installations on the top of the valve seat unit 1. Hole 3, where the mounting hole 3 is used to install the solenoid valve, the solenoid valve is installed on the top of the valve seat unit 1 through the bolts through the reserved holes of the solenoid valve, and a square groove 4 is arranged inside the valve seat unit 1 , and the square groove 4 is located between the two channels 2. The square groove 4 is connected with a control pipe 5. The solenoid valve controls the gas flow inside the channel 2 through the control pipe 5. One end of the control pipe 5 is provided with an internal thread 6, and the control pipe 5. The other end is provided with an external thread 7, and the external thread 7 is matched with the internal thread 6. Here, the diameter of the external thread 7 is about smaller than the diameter of the internal thread 6, so that one end of the external thread 7 can be inserted into one end of the internal thread 6, and the control pipe 5 is close to the inner thread 6. One end of the external thread 7 is connected with a sealing member 8, and the two sides of the valve seat unit 1 are connected with a clamping member 9. The clamping member 9 is used to connect two different valve seat units 1. When multiple solenoid valves are required to be installed , it is necessary to splicing multiple valve seat units 1 for installation. Since the valve seat units 1 in this solution have the same size, the front and rear of the control pipeline 5 just match. The valve seat units 1 are threadedly connected, and the seal 8 is located at the connection of the two valve seat units 1, which improves the sealing performance of the two valve seat units 1 and avoids leakage when the two valve seat units 1 are spliced. .
