Abstract
Disclosed is a pressure gauge antifreezing filling device. The device mainly overcomes the problem that a connection bend pipe of the conventional pressure gauge is likely to freeze. The device is characterized in that the upper end of an oil inlet valve (1) is connected to a tunnel (4), and the lower end of the oil inlet valve (1) is connected to a connection tee joint (2). A lower annular boss of the connection tee joint (2) is sleeved by a rapid connection press cap (5). The left end of the connection tee joint (2) is connected to an oil suction cylinder (3) that is internally provided with a piston (6). The piston (6) is connected to a screw (7). The screw (7) is connected to a seal cap (8) disposed at the left side of the oil suction cylinder (3). The left end of the screw (7) is connected to a hand wheel. The oil inlet valve (1) is communicated with the connection tee joint (2) and the oil suction cylinder (3). The pressure gauge antifreezing filling device is characterized by preventing the connection bend pipe from freezing.
Description
Technical field:
The utility model relates to the antifreeze charging point of oil extraction in oil field field well head instrument used, especially tensimeter.
Background technology:
In oil extraction in oil field field, need to be on outdoor equipment setting pressure table, with tensimeter, enroll data.At tensimeter, enrolled after data, tensimeter bridge piece easy freezing, causes damage tensimeter, affects data admission, is unfavorable for applying.
Utility model content:
In order to solve the problem of existing tensimeter bridge piece easy freezing.The utility model provides a kind of tensimeter antifreeze charging point.The antifreeze charging point of this tensimeter has the advantages that to prevent that tensimeter bridge piece from freezing.
The technical solution of the utility model is: the antifreeze charging point of this tensimeter comprises oil inlet valve, connecting tee and oil suction cylinder.Oil inlet valve upper end is connected with funnel, oil inlet valve lower end is connected with connecting tee, on the annular boss of connecting tee lower end, be socketed with quick connection pressure cap, connecting tee left end is connected with oil suction cylinder, oil suction cylinder is built-in with piston, and piston is connected with screw mandrel, and screw mandrel is connected with the sealing cap of oil suction cylinder left end, screw mandrel left end is connected with handwheel, and oil inlet valve communicates with connecting tee and oil suction cylinder.
The utlity model has following beneficial effect: the antifreeze charging point of this tensimeter is owing to adopting oil inlet valve upper end to be connected with funnel, oil inlet valve lower end is connected with connecting tee, on the annular boss of connecting tee lower end, be socketed with quick connection pressure cap, connecting tee left end is connected with oil suction cylinder, oil suction cylinder is built-in with piston, piston is connected with screw mandrel, screw mandrel is connected with the sealing cap of oil suction cylinder left end, screw mandrel left end is connected with handwheel, the structure that oil inlet valve communicates with connecting tee and oil suction cylinder, utilize oil suction cylinder to inject non-congealable oil toward tensimeter bridge piece, reach antifreeze object, and simple in structure.The antifreeze charging point of this tensimeter has the feature of the cleaning of exempting from thus.
Accompanying drawing explanation:
Accompanying drawing 1 is the utility model structural representation.
1-oil inlet valve in figure, 2-connecting tee, 3-oil suction cylinder, 4-funnel, 5-connects pressure cap fast, 6-piston, 7-screw mandrel, 8-sealing cap.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in accompanying drawing, the antifreeze charging point of this tensimeter comprises oil inlet valve 1, connecting tee 2 and oil suction cylinder 3.Oil inlet valve 1 upper end is connected with funnel 4, oil inlet valve 1 lower end is connected with connecting tee 2, on connecting tee 2 lower end annular boss, be socketed with quick connection pressure cap 5, connecting tee 2 left ends are connected with oil suction cylinder 3, oil suction cylinder 3 is built-in with piston 6, and piston 6 is connected with screw mandrel 7, and screw mandrel 7 is connected with the sealing cap 8 of oil suction cylinder 3 left ends, screw mandrel 7 left ends are connected with handwheel, and oil inlet valve 1 communicates with connecting tee 2 and oil suction cylinder 3.
The antifreeze charging point principle of work of this tensimeter, stop valve during use under first closing presure table, then unload tensimeter, with quick connection pressure cap 5, the antifreeze charging point of this tensimeter is connected on the short circuit of stop valve, open oil inlet valve 1, rotary screw 7, piston 6 can be moved to the left, to oil suction cylinder 3 inside, be filled noncongeable oil, after filling it up with, close oil inlet valve 1, then open pressure gage valve, rotary screw 7, piston 6 can move right, and makes non-congealable oil enter tensimeter bridge piece, thereby reaches antifreeze effect.
