Abstract
The utility model relates to an anti-freezing device, in particular to an anti-freezing package of a pressure taking device of a meter. The anti-freezing package comprises a package body, the package body has a cylinder structure, a liquid injection port is arranged at the top of the cylinder structure, a pressure taking port and a window are respectively arranged at the side parts, and a pressure guide port is arranged at the lower part. Compared with the prior art, the anti-freezing package has simple structure, low manufacturing cost, no power consumption, high metering accuracy and simple operation, and can thoroughly solve the freezing problem of a sampling device.
Description
Technical field
The utility model relates to a kind of defroster, particularly a kind of antifreeze antifreeze package of instrument pressure obtaning device of instrument and meter that is used for.
Background technology
Because winter temperature is lower, when the flow of usefulness instrument measurement water, steam or other water-bearing medias and pressure, the pressure obtaning device of instrument is easy to freeze.The freezing of water caused also easy deformation of pilot pipe breakage, differential pressure transmitter bellows easily, and gage work can't be continued.Currently used antifreezing measures generally are to install attemperator or heating tape additional in the sampler appearance, but these methods have not only increased power consumption, and have hidden danger easily, if temperature is low excessively, the medium in the connecting pipe can continue to freeze; And temperature is when too high, and the medium in the connecting pipe is vaporized easily, causes error in dipping.
The utility model content
The utility model is at the many defectives that exist in the prior art, provides a kind of simple in structure, the antifreeze package of instrument sampler of good freezing protection effect.
Realize above-mentioned purpose by the following technical solutions: the antifreeze package of a kind of instrument pressure obtaning device, comprise the package body, described package body is a tube structure, and the top of this tube structure is provided with liquid injection port, its sidepiece is respectively equipped with pressure tappings and form, and its bottom is provided with the pilot port.
Compared with prior art, the utility model is simple in structure, can thoroughly solve the frozen problem of sampler, and cost of manufacture is low, no power consumption, and the metering accuracy height, simple to operate.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
Referring to accompanying drawing 1, in the present embodiment, the antifreeze package of this instrument pressure obtaning device comprises package body 5, and package body 5 is a tube structure, and its top is provided with liquid injection port 2, is used to inject anti freezing solution, on this liquid injection port 2 valve is housed.The sidepiece of package body 5 is respectively equipped with pressure tappings 1 and form 3, and pressure tappings 1 one ends are connected the other end and package body 5 internal communication with the pressure export of the pipeline that needs to measure; Form 3 adopts clear glasses to be installed on the cylinder body outer wall, can clear observation cylindrical shell in the height of liquid level.The bottom of package body 5 is provided with the pilot port 4 with its internal communication, and this pilot port 4 is connected with the pilot pipeline.
Using method of the present utility model (illustrating):
1, be used for differential pressure flowmeter: a package is installed in the positive and negative pressure outlet at pipeline respectively, and is connected with the pressure tappings 1 of each package respectively.The pilot port of package bottom is connected with differential pressure transmitter.Open liquid injection port 2 valves, in package body 5, inject anti freezing solution, up to liquid level and pressure tappings 1 level by form 3 range estimation anti freezing solution, valve-off, like this, the medium that needs to measure enters package body 5 inside by sample tap, behind anti freezing solution, flow out by pilot port 4, finish antifreeze operation, carry out flow measurement smoothly.
2, be used for pressure measurement: the malleation outlet of pipeline is connected with the pressure tappings 1 of package, and the pilot port of package is connected with the pilot pipeline of differential pressure transmitter.Open liquid injection port 2 valves, inject anti freezing solution in package body 5, up to liquid level and pressure tappings 1 level by form 3 range estimation anti freezing solution, valve-off is so just finished antifreeze operation.
Claims (1)
1. the antifreeze package of instrument pressure obtaning device comprises the package body, it is characterized in that, described package body is a tube structure, and the top of this tube structure is provided with liquid injection port, and its sidepiece is respectively equipped with pressure tappings and form, and its bottom is provided with the pilot port.
