耐震压力表是用于石油、煤炭、地质等部门钻井设备上的安全和工艺指示仪表。在结构上与一般压力表有所不同,它主要由密封垫、膜片组、叉簧,传动指示机构及外壳等组成。因为这种仪表适用于高粘度、大粒度、易结晶、凝固(如水泥、泥浆)等介质的测量,所以接头螺纹直径较大,与我国
Seismic pressure gauge is used in petroleum, coal, geology and other departments of drilling equipment safety and process instructions instrument. Structurally different from the general pressure gauge, which is mainly composed of gaskets, diaphragm sets, hooks, transmission instructions and shell components. Because of this instrument for high viscosity, large particle size, easy to crystallize, solidified (such as cement, mud) and other media measurements, so the larger thread diameter, and our country
