Abstract
The utility model discloses a special defroster for a pressure meter. The special defroster for the pressure meter includes a pipe and a valve body. The valve body includes a main valve body and a pressure release valve body connected with each other. The main valve body is disposed in the pipe and is arranged in the radial direction along the pipe. The pressure release valve body is disposed outside the pipe and is arranged perpendicular to the axis of the main valve body. The main valve body is provided with a main valve base and a medium inflow channel and a medium outflow channel arranged on two sides of the main valve base. The wall of the medium inflow channel is provided with a medium inflow port. The medium inflow channel is equipped with a main valve rod. The medium outflow channel is inside provided with a capsule made of elastic material. The capsule is provided with a cavity accommodating medium. The top wall of the pressure release valve body is equipped with a pressure meter base through a bolt. After the special defroster for the pressure meter provided by the utility model is installed for using, the pipe is connected with an oil pipe and a water pipe of an oil field. The capsule is loaded with anti-freezing oil in advance. The pressure meter is installed on the pressure meter base. Since the anti-freezing oil enters into the pressure meter, the pressure meter is not frozen even when external environment temperature is comparatively low.
Description
Technical field
The utility model relates to the special-purpose defroster of a kind of tensimeter.
Background technology
It is very widely that tensimeter is used on the oil in oil field, water pipeline, because China is vast in territory, many oil fields are located in northeast, the high and cold area such as northwest, be arranged on the phenomenon that the tensimeter on open-air piping is damaged by frost in the winter time and happen occasionally, will affect normal oil producing operation once tensimeter is damaged by frost.The main cause that tensimeter is damaged by frost is oil, when the WATER AS FLOW MEDIUM in water pipeline or oil enter into tensimeter, cause medium to freeze because ambient temperature is too low and cause tensimeter to be damaged by frost.
The utility model content
Even the technical problems to be solved in the utility model is to provide the special-purpose defroster of tensimeter that a kind of ambient temperature lower pressure table also can not be damaged by frost.
for solving the problems of the technologies described above, the special-purpose defroster of the utility model tensimeter comprises pipeline and valve body, valve body comprises main valve body and the pressure release valve body that is interconnected, described main valve body is positioned at described pipeline and radially arranges along pipeline, and it is outer and be the vertical mode setting with the axis of described main valve body that described blowdown valve body is positioned at described pipeline, described pressure release valve body has the pressure release valve seat, is rotary with the pressure release valve rod, also is provided with the medium escape hole on the wall of this pressure release valve body, described main valve body has main valve seat and is positioned at medium flow channel and the medium flow pass of this main valve seat both sides, the wall of medium flow channel is provided with the MEDIA FLOW entrance, the medium flow channel passes through bonnet, sealing ring, gland and gland nut are equipped with main valve stem, be provided with the capsule of being made by resilient material in described medium flow pass, this capsule has the chamber that holds medium, the top end opening place of capsule has flanging, the roof of described pressure release valve body is equipped with pressure gauge base by bolt, the flanging at described capsule top end opening place is arranged between the diapire of the roof of pressure release valve body and pressure gauge base.
adopt the antifreezing device for pressure meter of said structure, the oil in pipeline and oil field when installing and using, water pipeline is connected, in the capsule of being made by resilient material, noncongeable oil is housed in advance, tensimeter is arranged on pressure gauge base, measuring oil, during water pipeline pressure, oil, medium in water pipeline enters by the MEDIA FLOW entrance on the wall of medium flow channel, enter into the medium flow pass by main valve seat, and then the capsule that extruding is made by resilient material makes noncongeable oil enter tensimeter, what enter due to tensimeter is noncongeable oil, even therefore ambient temperature lower pressure table can not be damaged by frost yet.
As further improvement of the utility model, described medium flow channel and medium flow pass are positioned at always on line substantially.
As another kind of improvement the of the present utility model, the relatively described medium flow pass of described medium flow channel is vertical mode and arranges.
The antifreezing device for pressure meter of above-mentioned two kinds of different structures can be according to the different laying condition choice for uses of oil field oil, water pipeline.If oil, water pipeline can preferably adopt medium flow channel relative medium flow pass to be the antifreezing device for pressure meter that vertical mode arranges apart from ground is low; If oil, water pipeline is higher apart from ground, can preferably adopt medium flow channel and medium flow pass substantially to be positioned at the special-purpose defroster of tensimeter on line always.
