Abstract
A kind of aviation pitot tube, be made up of pitot hole, gauge head, pole, static tube, stagnation pressure tube, orientation lever and baroport, pole is the steel pipe of one section of " 7 " font, the upper end cover of pole has gauge head, the pointed nose that side has is designed with pitot hole, the both sides, lower end of gauge head are designed with baroport, the lower bottom end of pole is provided with stagnation pressure tube, the right-hand member of stagnation pressure tube is provided with static tube, the left end of stagnation pressure tube is provided with orientation lever, the pitot tube volume of this utility model is little, is easy to carry, and is applicable to the measurement of aviation air flow amount.
Description
Technical field
The utility model relates to aviation pipe field, particularly a kind of aviation pitot tube.
Background technology
Pitot tube is a multiple platform bone of double-layer hollow curving right angle, with multiple pressure port, can measure fluid stagnation pressure and static pressure simultaneously.Support the use with differential pressure transmitter, Flow Measurement Display Meter.It is in petrochemical complex, metallurgical, power plant, electric power, widely use in the production run of the industries such as light textile, to gas, liquid, steam, water, the fluids such as air quantity carry out flow measurement, meet flow path direction at pitot tube head to have an aperture and be called pitot hole, " stationary point " is formed at this place, some baroports perpendicular to direction of flow are being had apart from head a distance. static pressure that each baroport is surveyed exports after equal pressure chamber is all pressed, because the flow velocity of the stagnation pressure of fluid and the difference of static pressure and detected fluid has the numerical relation determined, therefore can record rate of flow of fluid with pitot tube thus calculate the size of measured flux.
Utility model content
It is little that technical problem to be solved in the utility model is to provide a kind of volume, is easy to carry, and is applicable to the aviation pitot tube of the measurement of aviation air flow amount, to solve the above-mentioned multinomial defect caused in prior art.
For achieving the above object, the utility model provides following technical scheme: a kind of aviation pitot tube, be made up of pitot hole, gauge head, pole, static tube, stagnation pressure tube, orientation lever and baroport, pole is the steel pipe of one section of " 7 " font, and the upper end cover of pole has gauge head, and the pointed nose that side has is designed with pitot hole, the both sides, lower end of gauge head are designed with baroport, the lower bottom end of pole is provided with stagnation pressure tube, and the right-hand member of stagnation pressure tube is provided with static tube, and the left end of stagnation pressure tube is provided with orientation lever.
Preferably, described gauge head is capsule shape.
Preferably, between described static tube and stagnation pressure tube, O-ring seal is installed.
Preferably, described pitot hole is cellular, is made up of several aperture.
Preferably, the making material of described pole is titanium alloy.
Adopt the beneficial effect of above technical scheme to be: gauge head is capsule shape, and such design reduces the resistance of gauge head to air, greatly strengthen gauge head survey the degree of accuracy of air velocity; Be provided with O-ring seal between static tube and stagnation pressure tube, O-ring seal can make the sealing property of whole pitot tube more good, and the accuracy for surveyed air velocity serves guaranteeing role; Pitot hole is cellular, is made up of several aperture, such design can sensitive seizure from the air of true face; The making material of pole is titanium alloy, and the use of titanium alloy enhances the solidness of pole, also mitigates the weight of pitot tube simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of aviation pitot tube of the utility model;
Wherein: 1, pitot hole 2, gauge head 3, pole 4, static tube 5, stagnation pressure tube 6, orientation lever 7, baroport.
Embodiment
Preferred implementation of the present utility model is described in detail below in conjunction with accompanying drawing.
Fig. 1 shows the embodiment of a kind of aviation of the utility model pitot tube: a kind of aviation pitot tube, by pitot hole 1, gauge head 2, pole 3, static tube 4, stagnation pressure tube 5, orientation lever 6 and baroport 7 form, pole 3 is the steel pipe of one section of " 7 " font, the making material of pole 3 is titanium alloy, the use of titanium alloy enhances the solidness of pole, also mitigate the weight of pitot tube simultaneously, the upper end cover of pole 3 has gauge head 2, gauge head 2 is capsule shape, such design reduces the resistance of gauge head to air, greatly strengthen gauge head survey the degree of accuracy of air velocity, the pointed nose of side 2 is designed with pitot hole 1, pitot hole 1 is cellular, be made up of several aperture, such design can sensitive seizure from the air of true face, the both sides, lower end of gauge head 2 are designed with baroport 7, the lower bottom end of pole 3 is provided with stagnation pressure tube 5, the right-hand member of stagnation pressure tube 5 is provided with static tube 4, between static tube 4 and stagnation pressure tube 5, O-ring seal is installed, O-ring seal can make the sealing property of whole pitot tube more good, accuracy for surveyed air velocity serves guaranteeing role, the left end of stagnation pressure tube 5 is provided with orientation lever 6.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
