Abstract
The invention relates to a pipeline pressure monitoring device and specifically relates to an anti-freezing pressure gauge. The anti-freezing pressure gauge comprises a pressure gauge head and a pressure gauge base. The pressure gauge head and the pressure gauge base are communicated through an upper connector; the pressure gauge base is internally provided with a pressure straight-pipe cavity; the bottom end of the pressure gauge base is provided with a lower connector for connecting with a pipeline; and the lower connector is internally provided with a channel for communicating the pressure straight-pipe cavity and the pipeline. The bottom end of the pressure straight-pipe cavity is provided with a seal plug. The pressure straight-pipe cavity above the seal plug is filled with anti-freezing liquid. Compared with the prior art, the pressure straight-pipe cavity is filled with the anti-freezing liquid, so that when water pipeline pressure changes, water in a water pipeline pushes the seal plug, and furthermore, the pressure is transmitted by the anti-freezing liquid. Therefore, the defect that a conventional pressure gauge is easy to freeze is overcome fundamentally.
Description
Technical field
The present invention relates to pipeline pressure monitoring equipment, specifically, relate to a kind of anti-freeze pressure meter.
Background technology
Oil field is in the process of recover petroleum, and frequent outdoor use tensimeter, particularly water injection well onsite application tensimeter is very general.Be provided with an impulse straight tube cavity in manometric gauge stand, containing partial air in impulse straight tube cavity, when it be installed in high pressure water injection well lines uses time, the pressure of water pipeline inside will make the water of water pipeline inside will enter in impulse straight tube cavity.Water pipeline pressure is larger, and the volume of air in impulse straight tube cavity will be compressed less, and the volume that the water of water pipeline inside enters in impulse straight tube cavity is more.When carrying out oil producing operation the winter of cold, entering water in tensimeter impulse straight tube cavity will freezing and expansion, make the shape and structure generation deformation set of impulse straight tube cavity, build-up of pressure table pointer under atmospheric pressure state can not fall zero, make tensimeter lose accurate pressure measurement ability, produce to device security simultaneously and bring very big hidden danger.
Summary of the invention
The technical problem to be solved in the present invention overcomes above-mentioned defect, provides a kind of anti-freeze pressure meter.
For solving the problem, the technical solution adopted in the present invention is:
A kind of anti-freeze pressure meter, comprise pressure gauge outfit and pressure gauge base, be communicated with by top connection between described pressure gauge base with pressure gauge outfit, impulse straight tube cavity is provided with in described pressure gauge base, the bottom of pressure gauge base is provided with the lower sub for connecting tube, be provided with the passage being communicated with impulse straight tube cavity and pipeline in described lower sub, it is characterized in that: the bottom of described impulse straight tube cavity is provided with sealing-plug, in the impulse straight tube cavity above sealing-plug, be filled with anti freezing solution.
Beneficial effect: owing to have employed technique scheme, compared with prior art, the present invention is filled with anti freezing solution in impulse straight tube cavity, and when water pipeline pressure changes, the water in water pipeline passes through to promote sealing-plug, and then by anti freezing solution transmission of pressure.Like this, the defect that conventional pressure table is afraid of to freeze just fundamentally is overcome.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
With reference to Fig. 1, anti-freeze pressure meter of the present invention, comprises pressure gauge outfit 1 and pressure gauge base 3, and described pressure gauge base 3 is communicated with by top connection 2 with between pressure gauge outfit 1.Be provided with impulse straight tube cavity in described pressure gauge base 3, the bottom of described impulse straight tube cavity is provided with sealing-plug 5, is filled with anti freezing solution 4 in the impulse straight tube cavity above sealing-plug 5.The bottom of pressure gauge base 3 is provided with the lower sub 6 for connecting tube, is provided with the passage 7 being communicated with impulse straight tube cavity and pipeline in described lower sub 6.
When anti-freeze pressure meter of the present invention is arranged on and high pressure water injection well lines uses, when water pipeline pressure changes, the water in water pipeline passes through to promote sealing-plug 5, and then by anti freezing solution 4 transmission of pressure.Pressure passes to top connection 2 again, finally passes to pressure gauge outfit 1, and pressure gauge outfit 1 shows force value according to the pressure passed over by pointer.
