Abstract
This utility model relates to a pressure accquiring device for high temperture gas, which is charactered in that said device is mainly comprised by pressure guide connector 10 that has a presure accquiring tube 11, pressure guide connector 10 is connected with oil clyinder 7, in which silicone oil 6, piston 9 and sealing ring 8 are arranged; lower end of silicone oil passage 5 is seperated from the presure accquiring tube 11 of pressure guide connector 10 by piston 9, the gap between piston 9 and the inner wall of oil clyinder 7 is sealed by ''O'' seal ring; For the reason of adopting piston type silicone oil to transmit pressure and the pressure sensor is contacted with the silicone oil adequately, pressure will be passed on the presure accquiring film of pressure sensor without loss, and the accurcy of pressure measure is high; since presure accquiring film of pressure sensor is not contacted with high temperature directly,it extents the working life of pressure sensor and avoids the damage of pressure sensor caused by the stress of medium freezing, solves the problem of unsafety such as leakege ,explode caused by manufacture techique. Furthermore, it has the advantages of easy making and convinently installation.
Description
Technical field
The utility model relates to a kind of high-temperature gas pressure obtaning device.
Background technology
In the prior art to the pressure survey of high-temperature gas, usually adopt a very long pressure guiding pipe is installed in hot-gas channel, at the other end of pressure guiding pipe a pressure transducer being installed then measures, pressure guiding pipe mainly is to be used for making medium heat dissipation, reduction temperature, thereby reaches the life-span that prolongs pressure transducer.But since pressure guiding pipe to manufacturing process, special requirement is installed, not only make, install trouble, and easily since the manufacturing process problem cause as safety problems such as leakage, explosions; In addition, when working in the open air, when the gas in the pipeline does not flow under certain working condition or during emptying, the reason that reduces owing to temperature, just when temperature is lower than the three-phase freezing point temperature, the solidifying icing stress and will cause pressure transducer to damage of residual gas.
Summary of the invention
The purpose of this utility model is the shortcoming that exists at prior art, and designs a kind of problems such as leakage and explosion that can overcome, and is safe and reliable, makes a kind of high-temperature gas pressure obtaning device easy for installation.
The purpose of this utility model can reach by the following technical programs: a kind of high-temperature gas pressure obtaning device, mainly comprise pressure transducer 2 and be attached thereto the pressure obtaning device that connects, it is characterized in that pressure obtaning device mainly comprises the impulse joint 10 that is installed on hot-gas channel and the flow instrument, is provided with the pressure pipe 11 that communicates with pipeline and flow instrument gas, the oil cylinder 7 that is connected with impulse joint 10 is provided with silicone oil 6, piston 9 and O-ring seal 8 in the oil cylinder; And separate by piston 9 between the pressure pipe 11 of the lower end of in-oil cylinder silicone oil passage 5 and impulse joint, seal by zero RunddichtringO 8 between piston 9 and oil cylinder 7 internal chamber walls; Pressure transducer 2 is contained in the interface block 1, and the other end of oil cylinder 7 and pressure transducer 2 interface blocks 1 join, and the silicone oil 6 on the silicone oil passage 5 is contacted with pressure diaphragm 3 on the pressure transducer 2.
The utility model compared with prior art has the following advantages: owing to adopt piston type silicone oil to transmit pressure, the pressure transducer pressure fully contacts with silicone oil, and pressure is harmless to be delivered on the pressure transducer pressure diaphragm pressure survey accuracy height; Pressure transducer pressure diaphragm does not directly contact (temperature herein is no more than 100 ℃) with high-temperature medium, prolonged the mission life of pressure transducer, and avoided the damage of solidifying icing stress build-up of pressure sensor, the leakage that the solution pressure guiding pipe causes owing to the manufacturing process problem, unsafe problem of explosion owing to medium.The utility model also has and makes advantages such as simple, easy for installation in addition.
