The temperature-resistant high-pressure dusty medium pressure tapping device is wide in applicability and simple in structure, can be used for high-pressure media and running at certain high temperature, and accordingly the difficult problem of pressure tapping of high-temperature high-pressure dusty media in the industry is solved.
Description
Technical field
The present invention relates to the treatment facility of coal dust, particularly a kind of temperature-resistant high-pressure dusty medium pressure tapping device.
Background technology
At present, in pressure measurement technology,, all there is not different technical matterss in the medium that single-phase or two-phase is mixed for gas-liquid in the process of its pressure.But for medium containing dust, as the pressure survey of coal dust Pneumatic conveying pipeline, pressure pipe often occurs because of the leakage of coal dust and stop up, especially under hyperbaric environment, this problem is just more outstanding.
In the technology of existing use, mainly adopt in two ways and carry out: a kind of is to adopt enlarged tube depositing dust principle, add the structure that steam or pressurized air purge simultaneously, but this apparatus structure more complicated, especially adopt steam blowing also need insulation, and withstand voltage limited, in actual use, effect is also undesirable.Another kind is to adopt the barrier film of the materials such as rubber or plastics medium and measuring system isolation, but this systematic survey requires to be full of liquid, and temperature is not high, and barrier film is easily aging, affect measuring accuracy, in addition owing to can not under high pressure use by the impact of barrier film material.For above technical matters, once someone proposed a kind of easy pressure taking device for medium containing dust, but this structure employing is threaded, and exists equally poor sealing to cause the technical matterss such as leakage under high temperature, high pressure.
Summary of the invention
The present invention is directed to the deficiency of existing pressure obtaning device, a kind of temperature-resistant high-pressure dusty medium pressure tapping device is provided, the pressure signal that can be used for high temperature, high pressure medium containing dust takes out, there is good mechanical property and sealing property, and applicability is wide, simple in structure, and can be used for high-pressure medium and certain high temperature (approximately 300 ℃), thus solved a taking-up difficult problem for High Temperature High Pressure medium containing dust pressure in industry.
Technical scheme of the present invention is as follows:
A kind of temperature-resistant high-pressure dusty medium pressure tapping device, be installed on medium containing dust pipeline, it is characterized in that: comprise strainer tube, strainer tube overcoat and pressure adapter, strainer tube is connected in medium containing dust pipeline, the outer cover of strainer tube is connected to strainer tube overcoat, strainer tube puts outward and offers perforation, and pressure is taken over by perforation and is connected with strainer tube overcoat is vertical; The outside of the end that described pressure adapter is connected with strainer tube overcoat is provided with bearing ring, and for bearing high pressure, it is outside that bearing ring is close to strainer tube overcoat, and bearing ring two ends are fastening by flange.
Described strainer tube, strainer tube overcoat, bearing ring are all coaxial, and the axis direction perpendicular to strainer tube, strainer tube overcoat, bearing ring is taken in pressure.Described strainer tube overcoat is cylindrical, covers into pressure outward take over for the gas permeation strainer tube of medium containing dust pipeline through strainer tube.
Described pressure is taken over successively vertically through bearing ring, strainer tube overcoat.
Between described bearing ring and strainer tube overcoat, adopt O RunddichtringO to seal.
Described flange is concave surface band neck socket welding flange.
Between described bearing ring and flange, adopt O RunddichtringO to seal.
Between described strainer tube and strainer tube overcoat, adopt welding or viscose glue bonding.
Meanwhile, strainer tube also adopts sintering metal porosint to make, and can effectively prevent that dust leakage from arriving in pressure pipeline.
Described strainer tube overcoat is a circular tube shaped element housing in strainer tube outside, is convenient in medium containing dust pipeline gas permeation strainer tube and through strainer tube, covers into pressure outward and take over.
Beneficial effect of the present invention is as follows:
The present invention adopts sintering metal porosint as strainer tube, has good machinery and strainability; Adopt bearing ring and female flange to fix, can be used for the medium containing dust pressure under high temperature, high pressure; Adopt O RunddichtringO to seal, can accomplish good sealing effectiveness, there will not be the situations such as leakage, can effectively improve the accuracy of pressure; Applicability of the present invention is wide, simple in structure, and can be used for high-pressure medium and certain high temperature (approximately 300 ℃, actual temp is depending on adopted O type circle material), thereby has solved a taking-up difficult problem for High Temperature High Pressure medium containing dust pressure in industry.
