Abstract
The utility model discloses a self-sealing quick pressure monitoring device, solving the problems of cumbersome process, time waste and high use cost when pressure monitoring valves are used for monitoring data. A piston and a spring are arranged in a shell of the device, wherein an inverted T-shaped through hole is arranged in the piston; upper and lower seal rings are arranged on the outer wall of the piston; when the pistons moves down to compress the spring, the lower seal ring of the piston drops from the sealing surface so that the inverted T-shaped through hole is communicated with a wellhead and the pressure is conducted to a pressure gauge; and when the spring is reset, the lower seal ring of the piston returns to the original sealing surface, cuts off pressure conduction and is self-sealed. The device has the following beneficial effects: most of time can be relatively saved by using the device to monitor data; and the device is simple to operate and is low in use cost.
Description
Technical field
The utility model relates to the pressure obtaning device of auxiliary admission well head pressure data on the oil field.
Background technology
In oilfield process, need regularly monitor technological parameters such as temperature in the well head, pressure, common name admission data is so that grasp underground working, for the innovating reform of safety in production and technology provides data.Well head is carried out pressure, the pressure valve normally is set, on the well head pipeline like pressure ball valve, pressure stop valve etc.; The pressure valve is closed at ordinary times, during the admission data, on measuring with manometric screw thread, twines sealant tape; Then with screwed connection to the outlet of pressure valve; Open valve, cut-in pressure table, the well head pressure data that the admission pressure meter shows.Can find out that from foregoing description every admission a bite well is handled with regard to needing that pressure meter is carried out once sealing, and is promptly loaded down with trivial details time-consuming again; Also have plenty of, the multiple switching pressure measuring valve behind the door, situation that valve is not closed completely because of wearing and tearing have occurs, such valve is difficult to repair usually and integral body is scrapped, use cost is high.
Summary of the invention
The purpose of the utility model provides a kind of quick pressure obtaning device, when using this pressure obtaning device admission data, need not carry out encapsulation process; Only need pressure meter be installed and get final product; Pressure finishes, and this pressure obtaning device has self-styled function, can replace the pressure valve fully; And the consumable accessory of pressure obtaning device is sealing ring and spring, and use cost is cheap.
For realizing the foregoing invention purpose, the technical scheme that the application adopts is: the quick pressure obtaning device of self-sealing comprises housing, piston, spring and spring pressure cap; The main body of said housing is a hollow cylindrical, and the top of housing is provided with internal thread, with the pressure meter screwed connection; The tail end of housing is provided with internal thread; Be connected with the spring pressure cap, in the housing, set gradually piston and spring between pressure meter and the spring pressure cap, the tail end of housing or external screw thread is set; Be threaded with the pressure measuring valve outlet, or the tail end of housing is welded on the wellhead equipment; Said piston is the cylindrical structure that the bottom has positive stop lug boss; The upper and lower end face center of piston has counterbore; The upper surface counterbore is built-in with sealing ring, and pressure meter afterbody boss inserts and squeezes in this counterbore through sealing ring, and the sidewall of piston has twice O-ring seals groove up and down; Built-in sealing ring; On the body of piston, also have the inverted T-shaped intercommunicating pore in addition, the upper shed of intercommunicating pore is positioned at center, piston upper surface, and the both-side opening of intercommunicating pore is between the two seals circle of piston side wall; Spring is fixed between piston lower surface counterbore and the spring pressure cap, and the center of spring pressure cap is provided with through hole; Also have plenty of; When spring in the raw the time, piston is divided into two sections with the housing inner chamber, and wherein the residing housing inner chamber of piston is an epimere; Housing inner chamber below the piston is a hypomere; Following piece housing intracavity diameter is greater than the sealing ring external diameter on the piston side wall, and the two seals circle of piston side wall makes housing inner chamber epimere and housing inner chamber hypomere isolated each other, when spring is in compressive state; Following road sealing ring on the piston side wall gets into housing inner chamber hypomere, and the inverted T-shaped intercommunicating pore on housing inner chamber hypomere and the piston is connected.
When the housing tail end of this pressure obtaning device was provided with external thread structure, pressure obtaning device also comprised device pedestal, and base is the cap shape, and base is connected with the external screw thread of housing tail end, and the center of base is provided with through hole, and base is welded on the wellhead equipment.
The beneficial effect of the utility model:
One, reduce use cost: pressure measuring valve door switch originally after the phenomenon that regular meeting occurs being not closed completely because of wearing and tearing is difficult to repair usually, causes whole valve to scrap for several times.And after the long-term use of the quick pressure obtaning device of self-sealing, the problem that sealing ring breakage or back-moving spring elastic force descend only can occur, and the cost of changing above-mentioned parts greatly reduces use cost well below the cost of changing the pressure valve;
Two, increase work efficiency: during pressure, the pressure meter screw thread need not to twine sealant tape in admission, also without switch pressure valve, as long as the upper end that manometric screw thread is connected on housing promptly can read pressure.After unloading loose pressure meter, spring promotes sealing ring and resets, and that cuts off inverted T-shaped intercommunicating pore and well head automatically is communicated with the realization self sealss.Through measuring and calculating, admission a bite oil well casing pressure time shortened to 45 present seconds by original 5 minutes, had saved the operating time greatly, had improved operating efficiency.
Description of drawings
Fig. 1 is the structural representation of the quick pressure obtaning device of the application's self-sealing.
Fig. 2 is the structure of piston sketch map.
The specific embodiment
Below in conjunction with accompanying drawing the application is further described:
