Abstract
A novel turbine flowmeter comprises a barrel 1, flanges 2, a magnetic impeller 3, an impeller shaft 4, support rings 5, magnetic rings 6, magnetic shafts 7, a sensor 8, a converter 9 and an instrument 10. The barrel 1 and the flanges 2 can be optimized into an integer and can be connected in a sealed manner via welding or bonding, the support rings 5 are connected with inner sides of the flanges 2 in a threaded manner, the support rings 5 are in hollow annular structure with reinforcement ribs, the magnetic rings 6 are embedded inside the support rings 5, the impeller shaft 4 is serially connected in the middle of the magnetic impeller 3, the magnetic shafts 7 are embedded at two ends of the impeller shaft 4 and arranged inside the magnetic rings 6 in a same polarity manner, namely an N polarity corresponds to an N polarity and an S polarity corresponds to an S polarity, the sensor 8 and the converter 9 are arranged outside the barrel 1 and connected with the same in a threaded manner, and the instrument 10 is connected with the converter via a wire. The novel turbine flowmeter is applicable to mediums such as gas, liquid and steam.
Description
Technical field
The utility model relates to machinery and electric meter specialty, especially refers to a kind of Novel turbine flowmeter.
Background technology
We all will use metering many occasions in productive life, comprise water, gas, wet goods medium.The worm gear flowmeter is a kind of in numerous flow instruments, and it is 99122263.6 utility model patents that are called " turbo flow meter " that a patent No. is arranged, and has announced a kind of turbo flow meter, and it comprises: the shell with inflow entrance and escape hole; Housing in the enclosure is set, and housing receives fluid that the inflow entrance through shell enters and the escape hole by shell with fluid expulsion; Be arranged on rotationally the impeller in housing, it passes to flow measurement device with rotating force, and impeller comprises the outward extending blade of predetermined number; Fluid is directed on the blade of impeller the structure with wheel rotor; With the structure with fluid guiding discharge shell escape hole.Although this structure has realized the flow detection function of medium, because vane rotary has larger friction force, obviously have the defectives such as the flow of startup is high, sensitivity is low.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of low startup flow, highly sensitive new type worm wheel flowermeter for above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the scheme that adopts: this flowermeter includes cylindrical shell, flange, magnetic impeller, impeller shaft, magnetic axis, support ring, magnet ring, sensor, converter and instrument and forms.
As improvement, described cylindrical shell is connected with flange and is optimized for one and also can connects by welding or adhering and sealing.Support ring is connected with the flange inside thread, and support ring is the loop configuration of hollow belt reinforcement, and inside studs with magnet ring, and in the middle of magnetic impeller, string has the two ends of impeller shaft, axle to stud with magnetic axis, and magnetic axis is placed in magnet ring with same polarity side, and namely the N level is to the N level, and the S level is to the S level.
Improve, described sensor, converter are placed in outside cylindrical shell, are threaded connection with cylindrical shell again, and instrument is connected with converter by wire.
Improve, this Novel turbine flowermeter is applicable to media such as gas, liquid, steam again.
Compared with prior art, the utility model is by installing magnetic axis additional on magnet ring and impeller shaft and magnetic is repelled each other installing additional on support ring, can make magnetic axis rotation non-contiguously in magnet ring, greatly reduce friction force, thereby make flowmeter just can measure demonstration under a very little startup flow, realized low startup flow, highly sensitive target.

Fig. 2 is the side view of piece number 5
Embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, the new type worm wheel flowmeter of the present embodiment includes: cylindrical shell 1, flange 2, magnetic impeller 3, impeller shaft 4, support ring 5, magnet ring 6, magnetic axis 7, sensor 8, converter 9 and instrument 10 form.Its middle cylinder body 1 is connected with flange and is integrated or connects by welding or adhering and sealing, support ring 5 is connected with flange 2 inside threads, support ring 5 is the loop configuration of hollow belt reinforcement, inside studs with magnet ring 6, in the middle of magnetic impeller 3, string has impeller shaft 4 and two ends to stud with magnetic axis 7, magnetic axis 7 is positioned over magnet ring 6 inside by the same polarity direction, and namely the N level is to the N level, and the S level is to the S level.
Described sensor 8, converter 9 are placed in cylindrical shell 1 outside, are threaded connection with cylindrical shell 1, and instrument 10 is connected with converter 9 by wire.
Use procedure is described as follows:
By flange, this device is placed in the testing medium path, because magnetic force between magnet ring 6, magnetic axis 7 repels each other, make magnetic impeller 6 be in suspended state under the effect of magnetic force, therefore very little flow just can make it to rotate, sensor 8 passes to converter 9 with the magnetic signal of the magnetic impeller 6 sensed, converter 9 is that digital signal transfers shows to instrument 10 with this signal conversion processing, and the user just can see the traffic conditions of path medium in real time.
This Novel turbine flowmeter is suitable in media such as gas, liquid, steam.
