Abstract
A kind of on-line testing pressure sensor apparatus with pressure, comprising: atmospheric valve (1), centrosome (2), normal pressure module (3), pressure regulator valve (4); It is characterized in that: the centrosome (2) of described on-line testing pressure sensor apparatus with pressure is with atmospheric valve (1), pressure regulator valve (4) in " ten " shape structure, and the top of centrosome (2) is provided with normal pressure module (3).The utility model is applicable to the on-line testing of pressure transducer, prevents pressure transducer from damaging, handling safety, alleviates the labour intensity of workman, ensures that enterprise normally produces.
Description
Technical field
the utility model belongs to instrument check technical field, particularly relates to a kind of on-line testing pressure sensor apparatus with pressure.
Background technology
along with carrying out at Measurement Verification Work, demand for enterprise's continuous seepage and safety in production reality is more and more higher, in oilfield process, easily unsafe factor is there is in pressure transducer dismounting, censorship easily damages pressure transducer, and impact produce, therefore, on-line calibration and on-line testing work seem extremely have important.But, for how utilizing work on the spot pressure in on-line testing work, control the different spot pressure of admission and the requirement making it to meet vertification regulation is the difficult problem of a restriction on-line testing.
Summary of the invention
the purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of on-line testing pressure sensor apparatus with pressure.
the technical solution of the utility model comprises: atmospheric valve, centrosome, pressure regulator valve.The centrosome of described on-line testing pressure sensor apparatus with pressure and atmospheric valve, pressure regulator valve are " ten " shape structure, and the top of centrosome is used for installation code modular pressure, and bottom is for connecting production procedure.
atmospheric valve in above-mentioned on-line testing pressure sensor apparatus with pressure is provided with emptying head.
pressure regulator valve in above-mentioned on-line testing pressure sensor apparatus with pressure is made up of valve body, O-ring seal, plunger, center-pole, pressure cap, handwheel.Its plunger is provided with two seals circle, left end be provided with externally threaded center-pole and be connected, be arranged in valve body, the left end internal thread of center-pole and valve body is attached across and by the center pit of pressure cap, the left end of center-pole is provided with handwheel, and pressure cap is connected with the left end external thread of valve body.
principle of work: by rotating the handwheel of pressure regulator valve, drive the left and right motion of plunger level by center-pole, the pressure realized in on-line testing pressure sensor apparatus with pressure raises or reduces, and realizes on-line testing pressure transducer.
the beneficial effects of the utility model are: the on-line testing being applicable to pressure transducer, prevent pressure transducer from damaging, handling safety, alleviate the labour intensity of workman, ensure that enterprise normally produces.
Accompanying drawing explanation
fig. 1-the utility model rig-site utilization broken section structural representation.
in accompanying drawing, 1. atmospheric valve, 101. emptying head, 2. centrosomies, 3. normal pressure module, 4. pressure regulator valve, 401. valve bodies, 402.
