Abstract
The utility model provides an anti -freezing device of pressure gauge. It is freezing mainly to have solved outdoor manometer, the unsafe problem of pressure value. Valve gap (1) above install manometer, valve gap (1) and valve body (2) sealing connection insidely constitute the cavity together, the cavity intussuseption is filled with anti -icing fluid, installs piston (4) in the cavity, spring (3) are installed to piston (4) top, valve body (2) the below install on the valve. Has simple structure, convenient and practical's characteristics.
Description
Technical field
This utility model relates to petroleum production engineering, the Pressure gauge being mainly used on outdoor equipment in winter, specifically a kind of antifreezing device for pressure meter.
Background technology
Pressure gauge is the instrument showing bearing device system pressure size, for the pressure-bearing situation of bearing device pressure parts of looking over one's shoulder, Stress control within allowed band, is primary condition and the basic demand realizing bearing device safe operation.When running in the winter time, outdoor Pressure gauge interior section stagnant water, easily freeze, the registration of build-up of pressure table still rests on which original registration, but in the case of pressure oscillation, Pressure gauge remains on original reading, build-up of pressure is forbidden, this situation hazardness is very big, and more serious consequence can cause pipeline breaking.
Utility model content
For solving problem present in background technology, the utility model proposes one and prevent outdoor Pressure gauge freezing, force value is inaccurate, causes the antifreezing device for pressure meter of equipment superpressure.
Technical scheme: a kind of antifreezing device for pressure meter, including valve gap (1), valve body (2), spring (3), piston (4), described valve gap (1) is installed above Pressure gauge, valve gap (1) is sealed connected together with valve body (2), Inner Constitution cavity, is filled with anti-icing fluid in cavity, be provided with piston (4) in cavity, piston (4) is arranged above spring (3), and described valve body (2) lower section is arranged on valve；
Further, between described piston (4) and valve body (2), gap is 0.01 0.02mm；
Further, described piston (4) bottom is provided with gasket seal.
Providing the benefit that: by using the technical solution of the utility model, it is ensured that Pressure gauge will not be damaged by frost, this device of use in winter can have Pressure gauge of replacing in former 3 days for changing, and saves fee of material.
Accompanying drawing explanation
Fig. 1 is this utility model organigram.
In figure, 1-valve gap, 2-valve body, 3-spring, 4-piston.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described further.
A kind of antifreezing device for pressure meter as shown in Figure 1, including valve gap (1), valve body (2), spring (3), piston (4), described described valve gap (1) is installed above Pressure gauge, valve gap (1) is sealed connected together with valve body (2), Inner Constitution cavity, is filled with anti-icing fluid in cavity, be provided with piston (4) in cavity, piston (4) is arranged above spring (3), and described valve body (2) lower section is arranged on valve；Between described piston (4) and valve body (2), gap is 0.01 0.02mm；Described piston (4) bottom is provided with gasket seal, prevents anti-icing fluid from missing, seals.
Concrete, valve gap 1 and valve body 2 are stainless steel, principle according to hydraulic pressure transfer, pressure transmission piston 4 is had inside device, piston material is aluminum or polyethylene tetrafluoro, pressure transmission piston upper is equipped with spring 3, device is internal loads anti-icing fluid, anti-icing fluid is at subzero 60 DEG C, will not freeze, can ensure that Pressure gauge will not be damaged by frost, open pressure gage valve, liquid-driving piston upwards, the anti-icing fluid of piston upper is full of inside Pressure gauge, display force value, during closing presure meter valve, piston is under the action of the spring, return to bottom of device, play sealing function.
Claims (3)
1. an antifreezing device for pressure meter, including valve gap (1), valve body (2), spring (3), piston (4), it is characterized in that: described valve gap (1) is installed above Pressure gauge, valve gap (1) is sealed connected together with valve body (2), Inner Constitution cavity, is filled with anti-icing fluid in cavity, be provided with piston (4) in cavity, piston (4) is arranged above spring (3), and described valve body (2) lower section is arranged on valve.
Antifreezing device for pressure meter the most according to claim 1, it is characterised in that: between described piston (4) and valve body (2), gap is 0.01 0.02mm.
