Abstract

The utility model relates to a pressure gage protector which mainly solves the problem that a pressure gage is damaged because the traditional pressure gage is in direct contact with a medium to be tested. The pressure gage protector is characterized in that an inner shell (2) is fixed in an outer shell (1), an empty cavity (4) is formed between the inner shell (2) and the outer shell (1), the left and right sides of the inner shell are provided with through holes (5), pistons (3) are arranged on the left and right sides inside the inner shell (2), and a non-corrosive buffer solution is filled between the two pistons (3) in the inner shell (2); and a gage joint (6) for connecting a pressure gage is arranged on the upper middle part of the outer shell (1), the gage connector (6) is communicated with the inner shell (2), a lower joint (7) is arranged in the lower middle part of the outer shell (1), and the lower joint (7) is communicated with the empty cavity (4). The pressure gage protector has the characteristics of isolating corrosive media and preventing the corrosive media from entering the pressure gage to damage the same.

Description

The tensimeter protector
Technical field
The utility model relates to the used protective device of a kind of tensimeter, especially tensimeter protector.
Background technology
Tensimeter basically all directly contacts with measured medium at present, and measured medium is a high temperature pressure corrosion property medium, and then the damage of build-up of pressure table, makes tensimeter show that numerical value is inaccurate, finally causes machinery and personal injury.
Summary of the invention
Directly contact the problem that the build-up of pressure table damages with measured medium in order to solve existing tensimeter.The utility model provides a kind of tensimeter protector.This tensimeter protector has can isolate Korrosionsmedium, prevents to get into to damage manometric characteristics in the tensimeter.
The technical scheme of the utility model is: this tensimeter protector comprises shell body, inner housing and piston.Inner housing is fixed in the shell body, and between inner housing and shell body, forms the cavity of annular, and there is through hole the inner housing left and right sides; The left and right sides is equipped with piston in the inner housing; Be filled with non-corrosive damping fluid between the two-piston in the inner housing, there is the manometric meter connector of connection at the middle part on the shell body, is connected in meter connector and the inner housing; Shell body down middle part has lower sub, is connected in lower sub and the cavity.
1 above inner housing in the such scheme is fixed in the shell body, and between inner housing and shell body, forms the cavity of annular; Shell body is connected with blowdown valve under the side; Damping fluid is a water.
The utlity model has following beneficial effect: this tensimeter protector is owing to adopt inner housing to be fixed in the shell body; And between inner housing and shell body, form the cavity of annular; There is through hole the inner housing left and right sides, and the left and right sides is equipped with piston in the inner housing, is filled with non-corrosive damping fluid between the two-piston in the inner housing; There is the manometric meter connector of connection at the middle part on the shell body; Be connected in meter connector and the inner housing, shell body middle part down has lower sub, the structure that is connected in lower sub and the cavity.Utilize piston that measured medium and damping fluid are kept apart, Korrosionsmedium can not be got in the tensimeter, thereby effectively protected tensimeter, eliminate safe hidden trouble, guaranteed manometric accurate.This tensimeter protector has and can isolate Korrosionsmedium thus, prevents to get into to damage manometric characteristics in the tensimeter.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
1-shell body among the figure, 2-inner housing, 3-piston, 4-cavity, 5-through hole, 6-meter connector, 7-lower sub, 8-blowdown valve.
Embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
Shown in accompanying drawing, this tensimeter protector comprises shell body 1, inner housing 2 and piston 3.Shell body 1 all is the cylindrical of airtight pressure-bearing with inner housing 2, and 1 above inner housing 2 is fixed in the shell body 1, and between inner housing 2 and shell body 1, forms the cavity 4 of annular, and flowing in the cavity 4 is measured medium.There is through hole 5 inner housing 2 left and right sides, make cavity 4 and 2 interior connections of inner housing by through hole 5.The left and right sides is equipped with piston 3 in the inner housing 2, is filled with water or oil between the two-piston 3 in the inner housing 2; Be filled with non-corrosive damping fluid between the two-piston 3 in the inner housing 2, damping fluid is non-corrosive liquid, like water or oil; Measured medium promotes two-piston 3, and two-piston 3 promotes damping fluid, finally by damping fluid pressure is passed to tensimeter; Eliminate impulsive force, tensimeter is shown precisely.The middle part has and connects manometric meter connector 6 on the shell body 1, is connected in meter connector 6 and the inner housing 2, and there is lower sub 7 at 1 time middle part of shell body, is connected in lower sub 7 and the cavity 4, is linked to each other with equipment under test by lower sub 7.Shell body (1) is connected with blowdown valve 8 under the side, when accomplishing test operation, can put the residue measured medium in the cavity 4 by blowdown valve 8.
During actual the use:
This tensimeter protector is connected through meter connector 6 and tensimeter earlier, connect through lower sub 7 and equipment again, can normally use.Test operation can be put the residue measured medium in the cavity 4 through blowdown valve 8 after accomplishing.

Claims (4)
