The utility model solves the problem of the accuracy of the pressure measurement of a pressure gauge. The utility model is characterized in that the convex edge of the top end of a gland (2) is clamped and connected with a convex body (4) of a joint (1) after the inner wall of the gland (2) fixes a core body (3), the bevel at the top end of the core body (3) is in contact with a bevel at the convex body (4) of the joint (1), the inner cavity of the core body (3) is provided with a three-way piston (5), and one end of the piston is in contact with the bottom end of the joint (1), wherein the inner cavity of the joint (1) is provided with a spring (6). The utility model has the advantages of accurate data of pressure measurement and convenient and quick installation, pressure and operation.
Description
The utility model relates to a kind of oil-water well mouth pressure table pressure obtaning device, belongs to three-way piston-form tensimeter pressure obtaning device.
At present, on the oil-water well in oil field, be that matter analysis and research in oil supply field provide reliable and crucial data by the pressure in the well head admission well mostly.But tensimeter commonly used is a portable pressure gage admission device, main pressure transmission mode is indirect induction pressure transmission, when tensimeter top push rod promotes lower piston, produce reacting force and promote upper piston again, make tensimeter play pressure behind the liquid pressurized in the upper piston cylinder; When lower piston moved down, lower piston top and bottom and upper piston top and bottom produced the pressure equity simultaneously, and this moment, tensimeter demonstrated wellhead pressure.Can be owing to the pressure transmission link is many, be difficult to make that to enroll data accurate: moreover in use, the lower piston dead stuck phenomenon of becoming rusty appears easily, and the problem that fluid seepage is arranged or enter air in the upper piston cylinder, make the wellhead pressure of enrolling that deviation be arranged, thereby influence the pilot production and the adjustment measure in oil field, also the matter analysis of oil supply field has brought difficulty simultaneously.
The purpose of this utility model is to avoid the deficiency of above-mentioned technology, and a kind of admission wellhead pressure data precision three-way piston-form tensimeter pressure obtaning device accurately is provided.
The purpose of this utility model can reach by the following technical programs: this tensimeter pressure obtaning device is made up of joint, gland, the gland inwall fixedly makes the convex body of convex edge, gland top phase clamping head, the inclined-plane at inclined-plane, core body top phase contact connector convex body place behind the core body, the core body bore seal is equipped with stop,threeway and makes piston one end phase contact connector bottom, and the inner chamber of its center tap is equipped with spring.
Above-mentioned gland internal thread is core body fixedly; Stop,threeway touches with core body mutually by O-ring seal; Stop,threeway axially has two holes and communicates with its inner chamber.
The utility model has following advantage than above-mentioned prior art: because this pressure obtaning device has adopted the three-way piston-form pressure transmission, wellhead pressure is directly imported on the tensimeter, loss is not directly enrolled wellhead pressure, the accuracy height; Moreover be equipped with stop,threeway in the core body bore seal, make that tensimeter can not be subjected to the impact of original pressure: at the joint inner chamber spring is arranged when opening pressure; can play buffer action to tensimeter; when fast pressure relief, can play protection to tensimeter, install, pressure is simple and quick.
Accompanying drawing 1 is that structure of the present utility model is cutd open figure;
Accompanying drawing 2 is that the structure of Fig. 1 stop,threeway 5 is cutd open figure.
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, this tensimeter pressure obtaning device is made up of joint 1, gland 2, and there is the convex edge on the top of gland 2, gland 2 inner threads are core body 3 fixedly, the convex body 4 of gland 2 top convex edge phase clamping simultaneously 1 makes gland 2 and joint 1 be connected as a single entity, and precession gland 2 bands move together with joint 1; The inclined-plane at phase contact connector 1 convex body 4 places, inclined-plane, core body 3 top, when joint 1 was moved down, the inclined-plane at convex body 4 places moved to lower slider along inclined-plane, core body 3 top; Core body 3 inner chambers are equipped with stop,threeway 5 by O-ring seal 7, make piston 5 one end phase contact connectors 1 bottom, make when joint 1 moves down, piston 5 can be promoted downwards together, wherein stop,threeway 5 axially has two holes 8 and communicates (showing in conjunction with Fig. 2) with its inner chamber 9, reach threeway, make that tensimeter can not be subjected to the impact of original pressure when opening pressure; Inner chamber at joint 1 is equipped with spring 6, in order to play buffer action to tensimeter when the release.
During actual the use, joint 1 is connect tensimeter, the other end of core body 3 (bottom) connects well head.During pressure measurement, in the time of the clockwise precession of gland 2, driving joint 1 promotion stop,threeway 5 moves along core body 3 inwalls, when the annular seal space that leaves core body 3 when the hole 8 of piston 5 reaches the pressure measuring cavity of core body 3 bottoms, liquid enters into joint 1 bottom through the inner chamber 9 of piston 5 and two holes 8 and the pressure of liquid is passed to tensimeter, directly record pressure, accuracy height, not loss.During release, precession gland 2 drives joint 1 and moves up counterclockwise, until reaching gland 2 initial positions, piston 5 fluid pressure effect lower edge core body 3 inwalls in well move up, and hole 8 enters into the annular seal space of core body 3, seal up liquid, till piston 5 phase contact connectors 1 bottom.Operation is very easy for installation, pressure fast, is fit to promote the use of.
