DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The utility model provides Figure 1-3 The fluid medium pressure gauge shown is easy to disassemble, comprising a first pipeline 1, one end of which is fixedly connected to a filter interception mechanism 2, one end of which is fixedly connected to a control pipe 3, a surface of the control pipe 3 away from the filter interception mechanism 2 is provided with a control valve 4, the other end of the first pipeline 1 is fixedly connected to a sealed pipe 5, the inside of which is threadedly connected to a pressure gauge 6;

[0020] The filtering and intercepting mechanism 2 includes a turning tube 21 fixedly connected to one end of the first pipeline 1, a supporting tube 22 is arranged inside the turning tube 21, a flow hole is opened inside the supporting tube 22, a push spring 23 is fixedly connected to the outside of one end of the supporting tube 22 near the flow hole, a lower pressing plate 24 is fixedly connected to one end of the pushing spring 23, and a filter assembly 25 is connected to the side of the turning tube 21 away from the supporting tube 22 through a thread;

[0021] A replacement tube 251 is fixedly connected inside the filter assembly 25, and a guide tube 252 is fixedly connected inside the replacement tube 251. A guide hole 253 is opened on the surface of the guide tube 252, and an interception filter 254 is provided at one end of the guide tube 252. A blocking sheet 255 is sleeved on the side of the surface of the guide tube 252 away from the guide hole 253.

[0022] A water-blocking sheet 7 is fixedly connected to the side of the surface of the control pipe 3 close to the control valve 4, and the surface of the water-blocking sheet 7 is sprayed with anti-rust paint. A mounting pipe 8 is connected to the side of the inside of the control pipe 3 close to the control valve 4 through a thread.

[0023] The surface of the pressure gauge 6 is hinged with an opening and closing door 9, and the surface of the opening and closing door 9 is affixed with a reflective strip;

[0024] The surface of the first pipe 1 is sleeved with friction rings 10 , and the number of friction rings 10 is two.

[0025] Working principle of the utility model: when the personnel use it, after the installation pipe 8 is threadedly connected and installed at the position to be detected, the water blocking sheet 7 is fitted with the surface of the installation position, and the opening and closing door 9 is closed inside the pressure gauge 6. When the device needs to be operated, the control valve 4 is turned to drain the fluid liquid into the inside of the pressure gauge 6. When the fluid liquid enters the inside of the turning pipe 21 through the control pipe 3, the fluid liquid first passes through the inside of the guide pipe 252 and is drained out from the guide hole 253, and the flow inside the guide pipe 252 Impurities in the passing liquid are guided to the hole 253 and the intercepting filter 254 for interception and treatment. When the pressure is too high, the lower pressing plate 24 is lifted by the water flow, causing the push spring 23 to lift. When the pressure becomes smaller, the push spring 23 is reset to scrape off excess impurities on the guide tube 252. The position of the lower pressing plate 24 is higher than the guiding hole 253 on the surface of the guide tube 252. Large particles are intercepted by the lower pressing plate 24 and the blocking plate 255. When personnel are cleaning, they rotate the filter assembly 25 to take out the filter assembly 25.
