Abstract
A pressure-buffering device comprises an upper joint, a sealing gasket, a lower joint and a buffering plate; the upper joint is provided with an upper through hole, and the lower joint is provided with a lower through hole; the upper joint is connected with a pressure gauge and is connected with the lower joint; the sealing gasket is arranged between the upper end surface of the lower joint and the upper joint; the buffering plate is mounted in an inner cavity of the lower joint and is provided with a throttling orifice; when the pressure is increased, a pressure source gets in through the lower through hole, the buffering plate is pushed upwards under the action of the throttling orifice, and the liquid flows into the pressure gauge through the throttling orifice and an outside groove of the buffering plate at the same time after the buffering plate goes upwards; when the pressure is decreased, the buffering plate goes downwards, the lower end surface of the buffering plate is in contact with a shoulder surface of the inner cavity of the lower joint, the liquid can slowly flow out from the throttling orifice, the pressure decrease is not large, and the pressure is increased when the pressure is not decreased yet, so that the pressure oscillation in the pressure gauge is greatly reduced, even a common pressure gauge can be suitable for the working environment of pressure oscillation, and the replacing frequency of the pressure gauge can be reduced.
Description
Technical field:
The utility model is the equipment that pumping station in oil field is used, and is a kind of pressure buffer device.
Background technique:
Plunger pump, diaphragm pump are arranged in the pumping station in oil field, these pumps are when work, pressure can fluctuate, and vibration frequency is very fast, this working environment of ordinarily manometer incompatibility, and working life is short, need often to change, as adopt the shock-proof pressure gauge expense very high, therefore, adopt two kinds of pressure gauge Economy all bad.
Summary of the invention:
The purpose of this utility model is a kind of pressure buffer device of design, makes ordinarily manometer can adapt to the working environment of pressure surge, reduces and changes the pressure gauge number of times.
The purpose of this utility model is achieved in that by upper connection, sealing gasket, lower contact, cushion plate to be formed, upper connection has last through hole, lower contact has lower through-hole, upper connection is connected with pressure gauge, upper connection is connected with lower contact, between lower contact upper-end surface and the upper connection sealing gasket is arranged, in the lower contact inner chamber cushion plate is installed, cushion plate has throttle orifice.
The beneficial effects of the utility model are: the up and down of cushion plate alleviates the pressure surge in the pressure gauge greatly, and ordinarily manometer can adapt to the working environment of pressure surge, can reduce and change the pressure gauge number of times, has remarkable economic efficiency.
Description of drawings:
Accompanying drawing is the utility model embodiment's a erection drawing.
Specific embodiment:
Below in conjunction with accompanying drawing the utility model embodiment is described.
Embodiment is made up of upper connection 1, sealing gasket 2, lower contact 3, cushion plate 4, upper connection 1 has last through hole 5, lower contact 3 has lower through-hole 7, upper connection 1 is connected with pressure gauge, upper connection 1 is connected with lower contact 3, between lower contact 3 upper-end surfaces and the upper connection 1 sealing gasket 2 is arranged, cushion plate 4 is installed in lower contact 3 inner chambers, cushion plate 4 has throttle orifice 6.
When pressure raises, pressure source is after lower through-hole 7 enters, it is up to promote cushion plate 4 under the effect of throttle orifice 6, after cushion plate 4 is up, liquid flows in the pressure gauge through the outer side slot ditch of throttle orifice 6 and cushion plate 4 simultaneously, when pressure descended, cushion plate 4 was descending, and cushion plate 4 lower end surfaces contact with lower contact 3 inner chamber circular bead surfaces, liquid stream can only slowly flow out from throttle orifice 6, pressure descends little, and when pressure also had little time to descend, pressure raise once more, so, pressure surge in the pressure gauge alleviates greatly, and ordinarily manometer can adapt to the working environment of pressure surge, can reduce and change the pressure gauge number of times.
