Description

Technical Field

[0001] The utility model relates to the technical field of pressure gauges, and particularly relates to an explosion-proof and corrosion-resistant pressure gauge. Background Technique

[0002] A pressure gauge is a commonly used measuring instrument, mainly used to measure the pressure in liquids, gases, and solids. The working principle of the pressure gauge is based on the elastic deformation of the sensitive element under the action of pressure. When the measured medium enters the pressure gauge, its pressure acts on the sensitive element, causing it to produce elastic deformation. This deformation is amplified through the transmission mechanism and transmitted to the indicating device, causing the pointer to deflect on the dial to indicate the measured pressure value.

[0003] According to the authorized announcement number CN218916658U, an explosion-proof and corrosion-proof pressure gauge is disclosed, which includes a pressure gauge assembly and an explosion-proof box. The pressure gauge assembly includes an outer shell body. A pressure gauge chip is arranged inside the outer shell body. A passivation layer is arranged on the inner wall of the outer shell body. A threaded connection head is arranged at the bottom of the outer shell body. A scale dial is arranged on the outside of the outer shell body. A first glass surface is arranged on the outside of the scale dial. The explosion-proof box is arranged outside the pressure gauge assembly. A cover plate is hinged to the through groove on the front side of the explosion-proof box. An explosion-proof plate is arranged inside the explosion-proof box. An adjusting mechanism is connected to the top of the explosion-proof plate. Two explosion-proof plates are symmetrically arranged on the adjusting mechanism, solving the problems that the glass fragments cause harm to the operator when the pressure gauge explodes and it is easily corroded by corrosive substances.

[0004] However, the above application still has deficiencies. The explosion-proof protection and anti-corrosion effect are achieved through the explosion-proof box, but the explosion-proof box is directly installed outside the pressure gauge, and it is very inconvenient to repair or replace the internal meter body using a flipped connection frame.

The cooperation of the slide rails and the installation of the explosion-proof glass can facilitate the observation of the pressure value of the watch body. After the explosion-proof glass is damaged, it is also convenient to use the slide rails to replace the explosion-proof glass.

[0009] Preferably, the mounting disc includes a disc body and mounting posts. The mounting posts are fixedly connected to the top of the disc body. Through holes are opened inside the fixing block, and the size of the through holes is larger than that of the mounting posts, so that the installation of the support base will not affect the fixation of the mounting posts and the watch body.
