Problems solved by technology
[0003] For the first connection and fixing method, because the pressure gauge is connected to the pressure regulating valve body through multiple screws, it takes a long time to disassemble and assemble, which reduces the assembly efficiency. At the same time, because the pressure gauge is completely embedded in the body, it also needs to provide installation space for the screws , the size of the pressure gauge is limited by the size of the body, so the dial of the pressure gauge is too small, and it is very inconvenient to observe
[0004] For the second connection and fixing method, although the pressure gauge is located outside the body of the pressure regulating valve, it is still necessary to use multiple screws to fix the cover. There are many disassembly steps, which are time-consuming, and the number of parts is large and the cost is high; the pressure gauge After installation, it is almost separated from the body of the pressure regulating valve, which is easy to be damaged; the pressure gauge and the cover are connected by threads, and the dial of the pressure gauge is difficult to align and it is not easy to observe

The invention discloses a connecting structure of a pressure regulating valve body and a pressure gage. The connecting structure of the pressure regulating valve body and the pressure gage comprises the pressure regulating valve body and the pressure gage, a positioning hole capable of containing the pressure gage is formed in the side face of the pressure regulating valve body, and a buckle is arranged on the back face of the pressure gage. A mounting groove which is in rotating clamping fit with the buckle is formed in the bottom face of the positioning hole, and a set screw capable of locking the buckle is arranged on the pressure regulating valve body. According to the connecting structure of the pressure regulating valve body and the pressure gage, while good locking and positioning of the pressure gage and the pressure regulating valve body are guaranteed, dismounting working time is saved, and the number of parts is reduced.
Description
technical field [0001] The invention relates to the field of pressure regulating valves, in particular to a connection structure between a pressure regulating valve body and a pressure gauge. Background technique [0002] At present, the connection and fixing methods of the pressure regulating valve body and the pressure gauge on the market usually have the following two structures: the body and the pressure gauge are connected by screws, and the pressure gauge is fixed on the body by multiple screws, or the body and the pressure gauge are connected by threads. Connection, rely on the cover or body and the screw on the pressure gauge to lock the pressure gauge. For example, the Chinese patent authorization announcement number: CN202302035U, the date of the authorization announcement is July 4, 2012, which discloses a new type of filter pressure regulating valve, which respectively discloses the connection and fixing methods of the above two types of pressure regulating valve...
