Description
Technical field
The medium that the utility model relates in a kind of device for the pressure in the measuring channel or in the container, particularly pipeline has corrosivity, perhaps contains more impurity, perhaps the easy character such as crystallization.
Background technology
At present, in the industry fields such as China's oil, chemical industry, medicine, to the various media in the pipe container as: traditional mode was when crude oil, sewage, mud and various chemical medium carried out gaging pressure---medium is directly by pipeline, and valve enters tensimeter and shows reading.But medium is if having corrosivity, impure and easy crystalline solid, will affect manometric degree of accuracy when adopting prior art, can make tensimeter minimizing in serviceable life when serious, tensimeter was lost efficacy, can cause simultaneously medium to reveal and overflow, cause environmental pollution, security incident occurs.
Summary of the invention
The utility model provides a kind of prior art deficiency that overcomes, can be owing to the mechanical pipe safety pressure device that affects the deficiencies such as the decline of build-up of pressure table measuring accuracy, inefficacy or the lost of life of medium.
Mechanical pipe safety pressure device of the present utility model is by being connected housing with tensimeter, be connected housing with tested pipeline and be arranged at respectively and be connected housing and the piston that is connected the housing inner chamber with tested pipeline and piston with tensimeter and consist of, the two ends that are connected housing with tensimeter wherein are respectively arranged with the structure that is connected and is connected with an end that is connected housing with tested pipeline with tensimeter, the other end that is connected housing with tested pipeline is provided with the structure that is connected with tested pipeline, 2 two piston spaces of the piston one that arranges respectively in the inner chamber of described two housings and piston interact, and the interaction by piston one and 2 two pistons of piston passes to tensimeter with the pressure of tested pipeline.
In the mechanical pipe safety pressure device of the present utility model, 2 two pistons of described piston one and piston all are on the same axis, and are provided with the O RunddichtringO on piston one and 2 two pistons of piston.
Mechanical pipe safety pressure device of the present utility model is when the state of use, and anti freezing solution is filled in the piston one of the housing that is connected with tensimeter and the space between tensimeter.
The utility model utilizes tested pipeline medium pressure thrust unit inner carrier to finish the pressure transmission, after adopting the utility model, because pipeline internal medium does not directly contact with tensimeter, but finish the pressure transmission by pressure thrust unit inner carrier, can solve the deficiencies in the prior art fully, make pressure-measuring system can safety, stable, accurately be applied to corrosivity, contain the pressure survey of impurity and easily-crystallized liquid, and the environment such as can satisfy outside high temperature, the hyperbaric chamber.
Because in the utility model structure, two lay respectively at tensimeter and connect housing and be connected the interior two-piston of housing with pipeline and be on the same axis, can make the pressure transmission accurately and reliably.Connect housing and be connected with pipeline on the piston one of housing and piston two two-pistons and be provided with the O RunddichtringO owing to being positioned at tensimeter, so can realize good sealing, avoided the phenomenon of measured medium seepage fully.
Since the utility model when real use state with housing that tensimeter is connected in piston and the space between tensimeter fill anti freezing solution, so just thoroughly overcome the disadvantage of the pressure-measuring system inefficacy of freezing to cause because of measured medium winter.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model, among the figure: be connected housing 1,2 with tensimeter for being arranged at the O shape circle on the piston, be connected housing 3 with tested pipeline, 4 for be arranged at the housing that piston two, 5 is with tensimeter is connected in pipeline is connected housing in piston one.
Embodiment
Accompanying drawing 1 is the schematic diagram of an embodiment of the present utility model.Below in conjunction with description of drawings.
By accompanying drawing 1 as seen, this pressure obtaning device is by being connected housing 1 with tensimeter and being connected housing 3 with tested pipeline, and the piston 1 that is arranged in the cavity that is connected housing 1 with tensimeter consists of with pistons 24 be connected housing 3 with tested pipeline in, and piston 24 acts on piston one 5 places.Be respectively arranged with O shape circle at piston 24 and piston 1, to realize sealing.Have respectively at the two ends that are connected housing 1 with tensimeter and to be provided with the structure that is connected with tensimeter, this structure that is connected with tensimeter generally speaking is one section internal thread that matches with external thread on the tensimeter, can be connected with pipeline the external thread that the internal thread that arranges on the housing matches and the structure that is connected the end that housing 3 is connected with tested pipeline is one section.The other end that is connected housing 3 with tested pipeline is provided with the structure that is connected with tested pipeline, and this segment structure can be one section screw thread, also can be directly welded on the tested pipeline.
When the use of reality, the left end of the piston 1 that shows at accompanying drawing 1 namely is connected in the housing cavity on piston one 5 left sides in the housing 1 with tensimeter, fill in advance anti freezing solution, and then the setting pressure table.The pressure of pipeline internal medium passes to tensimeter by pipeline pressure piston 24 and transmits piston 1 in normal operation, thereby finishes the pressure transmission, demonstrates pressure reading at tensimeter.
Thoroughly completely cut off being communicated with of medium in pipeline internal medium and the tensimeter by accompanying drawing 1 visible device of the present utility model, satisfy the demand of pressure medium in the measuring channel fully, can be safely, stable, accurately be applied to corrosivity, contain the pressure survey of impurity and easily-crystallized liquid, can satisfy high temperature, low temperature, high pressure, the environment such as outdoor.Pipeline connects housing and adopts the standardization Design of Screw Thread, makes it have widely adaptability, can directly replace former manometric installation and be equipped with pattern.
The utility model is through using in the test of Qinghai Oil Field water filling manifold, Applicative time is winter, site environment is open-air, the coldest monthly mean temperature-24.8 ℃, processing medium is water (oil well re-injection water), and on-stream pressure 25-50MPa. is installed in this device on the manifold first the anti freezing solution of then annotating in implementing, last setting pressure table is successively installed six.Device busy carried out site inspection after four months, tensimeter, pressure obtaning device are all excellent, and pressure gauge reading is accurate, reaches request for utilization fully.
Adopt before the prior art, Qinghai Oil Field water filling manifold is owing to being in for a long time the field work situation of low temperature, high pressure, after entering the winter on the manifold the original tensimeter of installing near half fluid seepage occurs soon, do not have the fault such as reading.In this situation, the scene is the measures such as cut-out, shutoff that the tensimeter on whole manifolds has been taked, and original tensimeter is all thrown aside, and measuring required manifold pressure reading needs to read from the waterflood pump gauge outfit, not only very inconvenience of operation, and have serious potential safety hazard.After adopting the utility model, thoroughly solved the problem that loses efficacy because of the pressure-measuring system of managing interior re-injection water and freezing to cause winter, intuitive and accurate reading out data has thoroughly been removed potential safety hazard at the scene, satisfied the safety in production requirement of device.
