Description

technical field

[0001] The invention relates to a pressure measurement transmission device, in particular to a transmission device for measuring the force value of an anti-seismic pressure gauge. Background technique

[0002] Because the anti-seismic pressure gauge can withstand instantaneous pressure shock and measure pulsating pressure, it is mainly used in places with particularly harsh environments and large vibrations, such as fracturing and cementing equipment in oil production. The existing anti-seismic pressure gauge uses the fork spring as the elastic element. The external pressure is transmitted to the ejector rod through the damping assembly. The ejector rod is supported by the diaphragm and transmits the pressure to the fork spring. The fork spring deforms and is converted into angular displacement through the amplifying indicator mechanism. , and then read the pressure value from the dial through the pointer; since the transmission ratio ...

Embodiment Construction

[0008] figure 1 As shown, for the present invention to create a specific embodiment of an anti-seismic pressure gauge force value transmission device, it includes a damping assembly 1, a fork spring 16, and an enlarged indicator mechanism. The fork spring 16 is composed of a fork spring seat 4 and a reed 6 , center top spring 7 is formed, and left and right reed 6 is connected on the fork spring seat 4, and center top spring 7 is positioned between left and right reed 6 and is connected as a whole with left and right reed 6, and described fork spring The seat 4 is provided with a guide hole for the ejector rod and a positioning hole for the diaphragm, and correspondingly provided with the ejector rod 3 and the diaphragm 2. The output end 5 of the ejector rod is matched with the central top spring 7, and the input end 14 is matched with the center hole of the diaphragm 2. The damping assembly 1 cooperates with the end surface of the diaphragm 2 through the gasket 12 . Describe...
