Abstract
The utility model discloses a device for reducing pressure fluctuation, which relates to support equipment for displaying pressure in oil field pump stations. The device comprises a pressure meter connector, a spring cover, a spring, a cylinder sleeve, a piston and a connector, wherein pressure meter connecting threads are formed at the upper part of the pressure meter connector; the lower part of the pressure meter connector is connected with threads between upper part threads and lower part threads of the connector; the lower part of the cylinder sleeve is connected with the upper part threads of the connector; the piston and the spring are installed in the cylinder sleeve; the spring cover is installed at the upper part of the cylinder sleeve; the spring is positioned between the spring cover and the piston; a pressure conducting hole is formed on lower part threads of the cylinder sleeve; a ring-shaped cavity is formed between the cylinder sleeve and the pressure meter connector; the ring-shaped cavity is communicated with the pressure conducting hole; and a through hole is formed in the connector. When pressure is increased or reduced, the piston is lifted or lowered, so that the cavity at the lower part of the piston is enlarged or reduced, pressure is buffered, the pressure fluctuation in a pressure meter is greatly reduced, a common pressure meter can fit for the operational environment of pressure fluctuation, the change frequency of pressure meters can be reduced, and the device has remarkable economic benefit.
Description
Technical field
The utility model is that pumping station in oil field shows the corollary equipment that pressure is used, and is a kind of pressure surge device that reduces.
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 surge device that reduces 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 GAUGE CONNECTOR, spring cup, spring, cylinder sleeve, piston, connecting head is formed, the pressure gauge connecting thread is arranged at GAUGE CONNECTOR top, screw thread is arranged at the connecting head bottom, being threaded between the top screw thread of GAUGE CONNECTOR bottom and connecting head and the lower thread, the cylinder sleeve bottom is threaded with connecting head top, piston is installed in the cylinder sleeve, spring, cylinder sleeve top mounting spring lid, spring is between spring cup and the piston, pressure conduction hole is arranged on the cylinder sleeve lower thread, between cylinder sleeve and the GAUGE CONNECTOR toroidal cavity is arranged, toroidal cavity communicates with pressure conduction hole, and through hole is arranged in the connecting head.
The beneficial effects of the utility model are: when pressure rising and decline, piston is landing with variation in pressure, the cavity of piston bottom is increased or reduce, make pressure obtain buffering, pressure surge in the pressure gauge alleviates greatly, 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
Fig. 1 is the utility model embodiment's a erection drawing.
Embodiment
Below in conjunction with Fig. 1 the utility model embodiment is described.
Embodiment of the present utility model is by GAUGE CONNECTOR 1, spring cup 2, spring 3, cylinder sleeve 4, piston 5, connecting head 6 is formed, the pressure gauge connecting thread is arranged at GAUGE CONNECTOR 1 top, screw thread is arranged at connecting head 6 bottoms, being threaded between the top screw thread of GAUGE CONNECTOR 1 bottom and connecting head 6 and the lower thread, cylinder sleeve 4 bottoms are threaded with connecting head 6 tops, piston 5 is installed in the cylinder sleeve 4, spring 3, cylinder sleeve 4 top mounting spring lids 2, spring 3 is between spring cup 2 and the piston 5, pressure conduction hole 8 is arranged on cylinder sleeve 4 lower thread, between cylinder sleeve 4 and the GAUGE CONNECTOR 1 toroidal cavity 7 is arranged, toroidal cavity 7 communicates with pressure conduction hole 8, toroidal cavity 7 communicates with pressure gauge inside, and through hole 9 is arranged in the connecting head 6.
GAUGE CONNECTOR 1 top screw thread Lu pressure gauge connects, connecting head 6 lower thread are connected with pressure source, pressure source imports into from through hole 9, when pressure raises, piston 5 base pressures increase, and pressure source promotes piston 5 up pressure springs 3, and the cavity of piston 5 bottoms increases, the absorption pressure source, the pressure of toroidal cavity 7 can not raise at once, and when pressure descended, piston 5 base pressures descended, it is descending that spring reset promotes piston 5, the cavity of piston 5 bottoms reduces, and the head pressure source can not descend the pressure of toroidal cavity 7 at once, when pressure also has little time to descend, pressure raises once more, so the pressure surge in the pressure gauge alleviates greatly, ordinarily manometer can adapt to the working environment of pressure surge, can reduce and change the pressure gauge number of times.
