Diaphragm type air manometer

Abstract

A diaphragm type air manometer disclosed by the present invention comprises a material conveying pipeline, the ring flanges are both fixedly connected at the two ends of the material conveying pipeline, and a first protection rack is fixedly connected at the tops of the ring flanges. The top of the material conveying pipeline is communicated with a connecting pipe, and the top of the connecting pipe penetrates the bottoms of the first protection rack and extends to the inner cavity of the first protection rack. A manometer head is arranged at the top of the connecting pipe, and a pressure pointer is arranged in the manometer head. According to the present invention, by arranging a second protection rack, a first insertion plate, a second insertion plate, a threaded hole, a threaded rod, amovable groove, a fastening block, a rotating handle, a limiting groove, a limiting block and a fastening groove, the manometer can be protected very well, is more convenient to use, and is not easy to touch accidently during the usage process, thereby guaranteeing the safety and the normal usage of the manometer, and even avoiding the problem that the materials in the pipe leak.

Description

technical field [0001] The invention relates to the technical field of pressure gauges, in particular to a diaphragm type air pressure gauge. Background technique [0002] A pressure gauge refers to an instrument that uses elastic elements as sensitive elements to measure and indicate pressure higher than the environment. It is widely used. It is used in almost all industrial processes and scientific research fields. Repair and maintenance factories and shops can be seen everywhere, especially in the process of industrial process control and technical measurement, because the elastic sensitive components of mechanical pressure gauges have high mechanical strength and convenient production, so mechanical pressure gauges are getting more and more popular. Wide range of applications. [0003] However, most of the traditional pressure gauges are exposed on the surface of the pipe body, and the protection effect is poor. It is easy to be accidentally touched during use, which ca...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a diaphragm type air pressure gauge, which has the advantages of good protection effect, and solves the problem that most traditional pressure gauges are exposed on the surface of the pipe body, the protection effect is poor, and it is easy to be accidentally touched during use. , and then easily cause damage to the pressure gauge, which not only delays the normal use of the pressure gauge, but even causes the leakage of the material inside the pipe body
