Utility model content
Thereby the utility model to revolve between the rotor openings of floating single rotor flowmeter and positioning baffle the serious and rotor no-fix of friction and fixes the problem that rotor sinks naturally in order to solve, and suspension single rotor gas meter is provided.
The utility model is to adopt following technical scheme to realize: suspension single rotor gas meter, , comprise hollow shell and be arranged on the rotor in hollow shell, it is corresponding that the interior top of hollow shell and bottom are fixed with position, the upper positioning tube that external diameter is identical and lower positioning tube, in upper positioning tube and in lower positioning tube, be respectively arranged with the upper bent axle that connected and composed by transverse axis and vertical axes and by the first vertical axes, the lower bent axle that the second vertical axes and transverse axis connect and compose, the vertical axes that goes up bent axle is arranged in positioning tube, the second vertical axes of lower bent axle is arranged in lower positioning tube, the second vertical axes coaxial cable of the vertical axes of upper bent axle and lower bent axle, rotor comprise horizontal plectane and with the fixing annulus of horizontal plectane surrounding, the upper face of horizontal plectane and lower face (are that rotor is in rotary course with the lower surface of upper positioning tube and the upper surface combinations of gaps of lower positioning tube respectively, not friction between horizontal plectane and positioning tube, and between horizontal plectane and positioning tube, seal), the upper end face of annulus and lower end face respectively with hollow shell in top end face and end clearance, bottom combination (be that rotor is in rotary course, not friction between annulus and hollow shell, and between annulus and hollow shell, seal), the linear combinations of gaps of barrel outer surface of the inside surface of annulus and upper positioning tube and lower positioning tube (is that rotor is in rotary course, not friction between annulus and positioning tube, and between annulus and positioning tube, seal), the outside surface of annulus and the linear combinations of gaps of the inside surface of hollow shell (are that rotor is in rotary course, not friction between annulus and hollow shell, and between annulus and hollow shell, seal), annulus one side has a vertical port, vertically port extends on horizontal plectane and on horizontal plectane and forms bell, on the both sides ring body of the vertical passage port of annulus, on correspondence position, have bearing mouth and be fixed with bearing, the center of horizontal plectane is provided with center pit, in center pit, be fixed with centre bearing, the first vertical axes of lower bent axle is inserted in centre bearing, and the upper end of the first vertical axes and the transverse axis of upper bent axle of lower bent axle are connected, between the sidewall of hollow shell and upper positioning tube and lower positioning tube, be fixed with the baffle plate that is positioned at horizontal plectane bell place, on the sidewall of the hollow shell of baffle plate both sides, have air intake opening and gas outlet, air intake opening and gas outlet communicate with draft tube and escape pipe respectively, draft tube and escape pipe are located at hollow shell outside, fixing with hollow shell sealing, hollow shell outer end is also fixed with sensor, sensor is connected with the vertical axes of upper bent axle.
The common space surrounding of rotor, upper positioning tube, lower positioning tube and hollow shell inner circle forms measuring room.During work, gas flows in measuring room from air intake opening, in measuring room, can form pressure reduction, under the effect of pressure reduction, rotor is done eccentric motion in hollow shell, effect due to dividing plate, gas can only move to gas outlet direction from air intake opening, when rotor forwards place, gas outlet to, the gas in measuring room to be discharged, the gas that simultaneously continues to enter in measuring room promotes back original position by rotor again, go round and begin again like this, rotor is made eccentric motion in hollow shell, and the number of turns that rotor rotates passes to sensor by upper bent axle, reaches the object of metering gas flow; And rotor is hanging shape in hollow shell, and between positioning tube and hollow shell, there is a good sealing, reduce air-flow leakage, in rotor rotation process and between positioning tube and hollow shell, do not rubbed simultaneously, improved serviceable life and the precision of flowmeter; Air intake opening and gas outlet are all arranged on a side of hollow shell, and gas has directly entered in measuring room, has also reduced the pressure loss.
The utility model has adopted bent axle and bearing location rotor, makes rotor realize suspension, and can effectively control each parts clearance; Air intake opening and gas outlet are all arranged on a side of hollow shell, have reduced the pressure loss; In rotor openings, place has set up bearing, makes the friction between rotor and baffle plate become movable friction from hard friction, has greatly reduced frictional resistance, has improved serviceable life and the precision of flowmeter.This utility model Jiang Wei China's gas dosing field increases the highly reliable volumetric metering new product of a kind of high precision.
