Description
Technical field
The utility model relates to the technical field of flowmeter, especially a kind of metal pipe float flow meter.
Background technology
Metal pipe float flow meter is a kind of variable area flow instrument measured based on float position.In our actual life, use quite extensive, for measuring flow velocity, a good equipment of the monitoring carried out.
But existing metal floater flowmeter does not often steadily cause flow loss because install, measure not accurate, or flow is too large at the beginning, causes Causing Flowmeter Damages, cisco unity malfunction, have impact on the efficiency of work, and waste cost.
Utility model content
The technical problems to be solved in the utility model is: in order to solve the prior art Problems existing in above-mentioned background technology, provide a kind of metal pipe float flow meter with by-pass valve control.
The utility model solves the technical scheme that its technical matters adopts: a kind of metal pipe float flow meter, the left end seat comprising cylindrical housings and be connected on housing and right end base, described left end seat and the end face of right end base are respectively arranged with sealing gasket, the inside of described cylindrical housings is provided with forward guides, the left end of described forward guides flushes mutually with the end face of left end seat, the middle and lower part of described forward guides is provided with valve, the right-hand member of described forward guides is connected with impeller, the top of described impeller is connected with transmitter, the right-hand member of described impeller is connected with rear guide, the middle and lower part of described rear guide is provided with valve too.
Further specifically, described forward guides, between impeller and rear guide, pin is adopted to connect.
Further specifically, the described impeller blade being positioned at the impeller of housing is odd number.
The beneficial effects of the utility model are: metal pipe float flow meter of the present utility model; adopt double-direction control valve; can when just starting to measure; effectively prevent from causing the damage of flowmeter on left right end base, to be provided with seal because flow is excessive simultaneously; serving the effect that seal protection flow does not run off on the one hand, is play to prevent from shaking the unnecessary impact brought flow measurement in measuring process on the one hand.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
In figure: 1, housing, 2, left end seat, 3, right end base, 4, sealing gasket, 5, forward guides, 6, by-pass valve control, 7, impeller, 8, transmitter, 9, rear guide.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of metal pipe float flow meter, comprise cylindrical housings 1 and the left end seat 2 be connected on housing 1 and right end base 3, described left end seat 2 and the end face of right end base 3 are respectively arranged with sealing gasket 4, by setting up sealing gasket 4 on the end face of left end seat 2 and right end base 3, effectively can avoid the leakage of liquid, make the sealing effectiveness of whole flowmeter better.
The inside of cylindrical housings 1 is provided with forward guides 5, the left end of described forward guides 5 flushes mutually with the end face of left end seat 2, the middle and lower part of described forward guides 5 is provided with valve 6, the right-hand member of described forward guides 5 is connected with impeller 7, the top of described impeller 7 is connected with transmitter 8, the right-hand member of described impeller 7 is connected with rear guide 9, the middle and lower part of described rear guide 9 is provided with valve 6 too, by setting up valve 6 respectively in the bottom of forward guides 5 and rear guide 9, each valve 6 individually can control forward guides 5 or rear guide 9, respective performance is regulated more to prepare.
Wherein, forward guides 5, between impeller 7 and rear guide 9, adopt pin to connect, adopt pin to connect and make connection each other more efficient and convenient, and there is good disguise.
The impeller blade being positioned at the impeller 7 of housing 1 is odd number, by adopting the impeller blade of odd number, does not namely adopt the impeller 7 of symmetric form, and make the rotation of impeller 7 more abundant, resistance is less, and it is more convenient to use, and more can meet the request for utilization of flowmeter.
This metal pipe float flow meter; adopt double-direction control valve; effectively can regulate flow during measurement; flow meter serves a kind of protective effect; left end seat 2 and right end base 3 have all installed sealing gasket 4; can effectively play shockproof effect, improve the degree of accuracy measured, also prevent the loss of flow.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on instructions, must determine its technical scope according to right.
