Dry type seismic pressure gauge

Abstract

The invention discloses a dry type seismic pressure gauge, and belongs to the field of pressure gauges. The dry type seismic pressure gauge is that the outlet end of a joint is communicated with the inlet end of an air guide tube; the outlet end of the air guide tube is communicated with the fixed end of a bourdon tube; the movable end of the bourdon tube is fixedly connected with a choke plug; the lower end of a lower clamping plate is fixedly connected with the choke plug; when the bourdon tube is elastically deformed to cause displacement, the whole machine core moves accordingly; a V-shaped drawing rod is arranged on a fixing plate which is fixedly connected with the joint; one end of the drawing rod is fixedly connected with a fixing block, and while the other end of the drawing rod is equipped with a bending section which is vertical to the plane of the machine core; an elongated adjusting groove is formed in a sector gear and sleeves the bending section of the drawing rod. The dry type seismic pressure gauge achieves the seismic capacity without pouring glycerinum or silicone oil into a surface housing, and is convenient to welding, material saving, low in production cost, and high in production efficiency.

Description

technical field [0001] The invention relates to the technical field of pressure gauges, and more specifically, relates to a dry shockproof pressure gauge. Background technique [0002] The movement assembly of the existing pressure gauge is generally composed of a joint, a Bourdon tube, a bulkhead and a movement with a connecting rod. One end of the Bourdon tube is welded with the air outlet of the joint, and the other end of the Bourdon tube is welded and sealed with the bulkhead. , the hole on the bulkhead and the connecting rod of the movement are fixedly connected by riveting pins. Under the action of pressure, the Bourdon tube elastically deforms to produce a displacement, which is amplified by the rotation of the linkage mechanism of the movement, and the pointer assembled on the movement shaft indicates the pressure value through the dial. [0003] The movement assembly of the general shock-resistant pressure gauge has a connecting rod transmission mechanism. One end...
