Description
Technical field
The present invention relates to a kind of gas circuit Fault detection filter and gas circuit detection filter method.
Background technology
In the fields such as metallurgy, chemical industry, building materials, electric power, usually to measure the parameter such as pressure, flow velocity, flow of gas circuit, under normal circumstances, because gas circuit airflow fluctuation is very large, cause measurement instrument display meeting very unstable, digital instrument display numeral is beated, and pointer meters can swing back and forth an equilibrium position, when some fluctuate little, can also estimate to read to obtain a mean value; When gas circuit airflow fluctuation is large, digital instrument or pointer meters just at all cannot readings, cause measuring gas path parameter.Software filtering can be taked to improve for digital instrument and export stationarity, but address this problem pointer meters is just bad.
Summary of the invention
The object of this invention is to provide a kind of gas circuit Fault detection filter, it can filtering source of the gas signal fluctuation spike and cut down fluctuation amplitude, source of the gas signal is exported steadily, and when gas circuit detects, meter reading is relatively stable.The present invention also provides a kind of gas circuit detection filter method.
Above-mentioned purpose is achieved through the following technical solutions:
A kind of gas circuit Fault detection filter, gas inlet pipe, air-capacitor chamber, gas output tube are communicated with successively, the screw be made up of screw rod and nut is provided with in described air-capacitor chamber, described screw rod inserts gas inlet pipe and is also threaded with gas inlet pipe, and the top of described screw rod is provided with for forming the inclined-plane of gas passage with gas inlet pipe.
Preferably, described air-capacitor chamber is cylindrical, and its diameter is 2 ~ 4 times of gas inlet pipe diameter, and length is less than the length of screw.
Preferred further, the angle of described inclined-plane and screw rod is 15 ~ 40 degree.
Preferably, the top of described nut is provided with groove, and the cross sectional shape of described groove is regular polygon.
Preferably, described gas circuit Fault detection filter also comprises pipeline and connects mouth, and described pipeline connects mouth and is set in respectively on gas inlet pipe and gas output tube.
The present invention further provides a kind of gas circuit detection filter method, comprise the following steps:
1) by the gas inlet pipe damping adjusting of gas to be measured by an adjustable gas channels size;
2) gas to be measured after damping adjusting, by after gas inlet pipe, enters a large volume air-capacitor chamber and carries out filtering, and then enter gas circuit measuring instrument by gas output tube.
Preferably, the gas channels size of described gas inlet pipe is regulated by the screw being located at gas inlet pipe one end, described screw is made up of screw rod and nut, described screw rod inserts gas inlet pipe and is also threaded with gas inlet pipe, and the top of described screw rod is provided with for forming the inclined-plane of gas passage with gas inlet pipe.
In the present invention, screw can increase the resistance of the air-flow of fluctuation, when air-flow is behind the air-capacitor chamber of excessive bulk, gets final product the parameter signal that output smoothing is stable.The present invention passes through the spike of gas circuit damping gentle capacitor filter double action filtering source of the gas signal fluctuation and cuts down fluctuation amplitude, and make source of the gas signal export steadily, when gas circuit detects, meter reading is relatively stable.By the length of adjusting screw(rod) in gas inlet pipe, the channel sized just between adjustable inclined-plane and gas inlet pipe, and then regulate gas circuit damping, change smoothness and the response time of output signal.Groove is established on the top of nut, is conveniently to regulate screw from gas output tube insertion with spanner.Pipeline connects mouth and is convenient to the present invention and connects gas circuit and detecting instrument.The features such as it is simple that the present invention also has structure, easy to use, can be widely used in the measurement of the flue gas pressure in the fields such as metallurgy, chemical industry, building materials, electric power, flow velocity, flow.

Specific embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described in detail.
Embodiment:
A kind of gas circuit detection filter method, comprises the following steps:
1) by the gas inlet pipe damping adjusting of gas to be measured by an adjustable gas channels size;
2) gas to be measured after damping adjusting, by after gas inlet pipe, enters a large volume air-capacitor chamber and carries out filtering, and then enter gas circuit measuring instrument by gas output tube.
The gas circuit pore size of described gas inlet pipe is regulated by the screw being located at gas inlet pipe one end, described screw is made up of screw rod and nut, described screw rod inserts gas inlet pipe and is also threaded with gas inlet pipe, and the top of described screw rod is provided with for forming the inclined-plane of gas passage with gas inlet pipe.
Equipment used in the method as shown in Figure 1 and Figure 2, a kind of gas circuit Fault detection filter, gas inlet pipe 1, air-capacitor chamber 2, gas output tube 3 are communicated with successively, the screw 4 be made up of screw rod 41 and nut 43 is provided with in described air-capacitor chamber 2, described screw rod 41 inserts gas inlet pipe 1 and is threaded with gas inlet pipe 1, the top of described screw rod 41 be provided with one with screw rod 41 one-tenth 30 degree of angles for forming the inclined-plane 42 of gas passage with gas inlet pipe.Described air-capacitor chamber 2 is cylindrical, and its diameter is 3 times of gas inlet pipe 1 diameter, and length is slightly less than the length of screw 4, avoids screw 4 to come off from gas inlet pipe 1.The top of described nut 43 is provided with groove 44, and the cross sectional shape of described groove 44 is regular hexagon.On described gas inlet pipe 1 and gas output tube 3, also sheathed pipeline connects mouth 5.
During use, first the M6 hex wrench matched with regular hexagon groove 44 is inserted from gas output tube 3, the distance of set screw 4, making to be formed between inclined-plane 42 and gas inlet pipe 1 can the passage that flows through of air feed, then press shown in Fig. 3, by the gas inlet pipe 1 in the present invention, gas output tube 3 connects mouth 5 and pitot tube 6 respectively by pipeline, measurement instrument 7 connects, whether the display numeral of observing measurement instrument is stablized, if unstable, then take off the sheathed pipeline of gas output tube 3 and connect flexible pipe on mouth 5, hex wrench is inserted output and connects mouth, the size in space is regulated with hex wrench, the length of screw rod 41 in gas inlet pipe 1 is shorter, space is larger, otherwise it is then less, can regulate according to the pressure or flow velocity measuring gas circuit, if pressure or flow velocity large, then reduce space, increase damping, if pressure or flow velocity little, then increase space, reduce damping.And then the system that connects is tested, observe display numeral, repeatedly debug, beat on a small quantity until display numeral only has, accurate numeral can be read and be advisable.
