Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pressure gauge technology and relates to a fluid medium pressure gauge with an anti-clogging pressure measuring channel. Background Technology
[0002] Pressure gauges are instruments that use elastic elements as sensing elements to measure and indicate pressures higher than ambient pressure. They are extremely common, found in almost all industrial processes and scientific research fields. They are ubiquitous in areas such as heat pipe networks, oil and gas transmission, water and gas supply systems, and vehicle repair and maintenance shops. Especially in industrial process control and technical measurement, mechanical pressure gauges are increasingly widely used due to the high mechanical strength and ease of manufacture of their elastic sensing elements.
[0003] Traditional fluid pressure gauges lack protection at the inlet pipe at the bottom. Over time, excessive accumulation of impurities can easily cause blockages at the inlet pipe, necessitating improvement. Summary of the Invention
[0004] The purpose of this invention is to provide a fluid medium pressure gauge with an anti-clogging pressure measuring channel to solve the problems mentioned in the background art.
[0005] The objective of this utility model can be achieved through the following technical solutions:
[0006] A fluid medium pressure gauge with an anti-clogging pressure measuring channel includes a pressure gauge body, an inlet pipe body, and side branch pipes. The inlet pipe body is located at the bottom of the pressure gauge body. Side branch pipes communicating with the inlet pipe body are located on both sides of the inlet pipe body. Two arc-shaped filter screens are installed inside the inlet pipe body. One end of the arc-shaped filter screen extends into the interior of the side branch pipe. A support arm is provided on one side of the top of the arc-shaped filter screen.
[0007] In the aforementioned fluid medium pressure gauge with an anti-clogging pressure measuring channel, the bottom end of the arc-shaped filter screen is provided with a mesh frame, and a roller is movably arranged inside the mesh frame.
[0008] In the aforementioned fluid medium pressure gauge with an anti-clogging pressure measuring channel, a pressure plate is provided at the bottom end of the inlet pipe, and a threaded head is provided at the bottom end of the pressure plate.
[0009] In the aforementioned fluid medium pressure gauge with an anti-clogging pressure measuring channel, the side branch pipe is provided with an impurity treatment chamber, and the impurity treatment chamber is connected to the inside of the inlet pipe.
[0010] In the aforementioned fluid medium pressure gauge with an anti-clogging pressure measuring channel, a glass window is provided on the outer wall of the side branch pipe, and a maintenance cover is threaded to one end of the side branch pipe.
[0011] Compared with the prior art, the advantages of this utility model of a fluid medium pressure gauge with an anti-clogging pressure measuring channel are as follows:
[0012] This application provides side branch pipes on both sides of the inlet pipe, and an arc-shaped filter screen opening to both sides is provided at the connection between the inlet pipe and the side branch pipe. After the pressure gauge body is connected to the pipeline, the fluid inside the pipeline can flow directly to the pressure gauge body through the inlet pipe. At the same time, impurities in the fluid can be filtered through the arc-shaped filter screen and then guided into the impurity treatment chamber. In this way, the inspection cover can be opened for cleaning. This structural design will not block the side pressure channel of the pressure gauge body and can be widely used.
