Abstract
The utility model relates to a pressure taking device of a double-prevention pressure-measuring meter, which solves the problem of the pressure taking accuracy existing in a pressure meter. The utility model is characterized in that the lower part of a pressure transmission sleeve (2) provided with a lug boss is fixed with a piston (6), and the axial direction of the piston (6) is provided with a through hole (7). The outer wall of the piston (6) is in contact with a switch sleeve (5), and the upper and the lower axial distance difference of the switch sleeve (5) is a positive number. The lug boss of the pressure transmission sleeve (2) is fixed with the switch sleeve (5) by a screw thread after covered by a press cap (4). The utility model has the advantages of accurate data, easy installation, and convenient and quick pressure taking.
Description
The utility model relates to a kind of oil-water well mouth pressure table pressure obtaning device, the two anti-pressure gauge pressure obtaning device of particularly antitheft antifreeze and fast quick-acting.
The PRESSURE DATA of the oil-water well in oil field is 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 pressure meter commonly used is to transmit pressure by piston, and demonstrates well head pressure on pressure meter.Can be difficult to make the data of enrolling to conform to the actual pressure data owing to the pressure transmission link, error be bigger, creates a false impression and influences production to actual production situation.
The purpose of this utility model is to avoid the deficiency of above-mentioned technology, and provides a kind of admission pressure data precision two accurately anti-pressure gauge pressure obtaning devices.
The purpose of this utility model can reach by the following technical programs: this pressure obtaning device is made up of pressure meter, pressure transmission cover, pressure tube, piston, the pressure meter pressure transmission cover that links to each other, it is characterized in that: the pressure transmission cover bottom fixed axis that boss is arranged is to the piston that through hole is arranged, the axial distance difference was the switch cover of positive number about piston outer wall touched mutually, and the boss of pressure transmission cover is pressed rear thread floatless switch cover by the pressure cap cover.
The utility model has following advantage than above-mentioned prior art: because this pressure obtaning device can make measured medium directly be delivered on the pressure meter from pressure tube by piston hole, and not loss midway, measured data is accurate; Moreover be connected with well head pressure measurement seat by pressure cap, be convenient for carrying, stop stolen and by being frozen phenomenon, applicability is very strong, is convenient to promote the use of.
Accompanying drawing 1 is that structure of the present utility model is cutd open figure;
Accompanying drawing 2 is the conventional structure graphs when pressure measurement not.
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, this pressure obtaning device is made up of pressure meter 1, pressure transmission cover 2, pressure tube 3, piston 6, pressure meter 1 continuous pressure transmission cover 2, pressure transmission cover 2 has boss, and its underpart fixed piston 6, piston 6 through hole 7 axially arranged, piston 6 outer walls touch switch cover 5 mutually, wherein the last axial distance of switch cover 5 is a positive number with following axial range difference, make the through hole 7 of piston 6 when the bottom of switch cover 5, the well medium can enter in the pressure tube 3 from through hole 7, and certain piston 6 is with switch cover 5 and pressure transmission cover 2 touches mutually or there is sealing ring 9 in bearing; The boss of pressure transmission cover 2 is pressed the back and screw thread floatless switch cover 5 by pressure cap 4 covers.
Under the regular situation, this pressure obtaning device is welded on the well head by overlapping 5 bases of fixing 10 with switch.When the needs pressure, manometric pressure transmission cover 2 is aligned switch cover 5, push down the boss of pressure transmission cover 2 then with pressure cap 4, screw thread precession switch overlaps 5 simultaneously, dwindles the gap of pressure transmission cover 2 and switch cover 5 this moment gradually, and while piston 6 is descending relatively, until switch cover 5 and pressure transmission overlap 2 touch mutually till, through hole 7 is in the bottom of switch cover 5, and the well medium enters pressure tube 3 directly to pressure meter 1 by through hole 7, and measured data is accurate.
After pressure measurement finishes,, and then break away from switch cover 5 with pressure cap 4 opposite spins.Piston 6 is return under pressure, makes through hole 7 be in the top of switch cover 5, and sealing is tight.Pressure meter 1 can be taken back keeping by the people, has stopped thoroughly that pressure meter is stolen to be frozen phenomenon.As seen this pressure meter pressure and fitting operation are very convenient quick, are fit to promote the use of.
Claims (1)
1, a kind of two anti-pressure gauge pressure obtaning device, form by pressure meter (1), pressure transmission cover (2), pressure tube (3), piston (6), pressure meter (1) the pressure transmission cover (2) that links to each other, it is characterized in that: pressure transmission cover (2) the bottom fixed axis that boss is arranged is to the piston that through hole (7) are arranged (6), the axial distance difference was the switch cover (5) of positive number about piston (6) outer wall touched mutually, and the boss of pressure transmission cover (2) is pressed rear thread floatless switch cover (5) by pressure cap (4) cover.
