Abstract

The utility model provides a shock-proof joint for pressure gauge, comprising an upper contact 3, a mid contact body 8, a lower contact 13, an absorber 11, etc. The upper contact 3 is provided with a general pressure gauge, the whole device is installed on an equipment which needs working pressure measuring; when the equipment works, the actuating medium thereof forces a medium separating membrane 16 to compress the actuating silicon oil medium in a surge chamber 15, the actuating silicon oil medium flows through an oil passage pipe 9 and a surge chamber 6 to transmit the pressure to a pressure gauge by a damping plug 4, and the working pressure is indicated. Not all the sharp shock of the working equipment is transmitted to the pressure gauge by means of the absorber 11 buffer action so that the service life of the pressure gauge is extended and the work efficiency is increased.

Description

Shock-proof joint for pressure gauge

The present invention is mainly used in industrial, is specially adapted to a kind of seismic pressure gauge connector of well drilling industry.

At present, the UP table is because no aseismatic mechanism measure, is used for showing pressure on the plant equipment of sharp pounding, cannot stand strong vibrations, the very easily malfunctioning or damage of build-up of pressure table, thus influenced mechanical operate as normal.

The objective of the invention is,, increase work efficiency, designed a kind of seismic pressure gauge connector in order to improve manometric serviceable life.

Below be particular content of the present invention and most preferred embodiment:

As shown in drawings, the present invention is mainly by joint 3, middle junctor 8, compositions such as lower sub 13 and vibroshock 11, damping plug 4 is housed in top connection 3, jackscrew 5, top connection 3 is adopted thread connection with middle junctor 8, buffering filler 7 is housed above middle junctor 8, jackscrew 17, there is a vibroshock 11 to be contained in middle junctor 8 lower ends and lower sub 13 upper ends, the lower end is fixing with medium diffusion barrier 16 by pressure ring 21 in lower sub 13, lower sub 13 inside above medium diffusion barrier 16 are provided with surge chamber 15, buffering filler 20 and work silicone oil medium are housed in the surge chamber 15, there are oil circuit pipe 9 upper ends to be welded with sealing gasket 18, the lower end is welded with sealing gasket 19, oil circuit pipe 9 upper ends connect firmly by jackscrew 17 and middle junctor 8, and the lower end connects firmly by jackscrew 14 and lower sub 13.Jackscrew 5 in top connection 3 has two identical dead rings 12 with damping plug 4 joints, and connects with middle junctor 8 and lower sub 13 respectively by four identical jackscrews 10.

Principle of work of the present invention is, adopt UP table 1 and antidetonation joint 2 to be linked together and to be contained on the working equipment, during work, promote the medium diffusion barrier by working equipment with the actuating medium that certain pressure transmits, working pressure will be by oil circuit pipe 9, surge chamber 6 and process damping plug 4 are delivered to tensimeter 1 indicated pressure, owing to adopt vibroshock 11, the sharp pounding of working equipment is decayed, tensimeter does not directly bear sharp pounding of machinery itself, thus make ordinarily manometer can be in abominable vibration environment operate as normal.

Advantage of the present invention is:

1, anti-seismic performance is good, can improve manometric serviceable life;

2, make simply, with low cost.

Description of drawings:

Fig. 1 is tensimeter and seismic pressure gauge connector assembling schematic appearance;

Fig. 2 is the structural drawing of seismic pressure gauge connector, can be used as Figure of abstract.
