Abstract
The utility model discloses a kind of gear driven type water valves, including pipeline, it is fixed on the shell of pipeline external, the valve being mounted on pipeline is provided with annulus on the valve rod of valve, and annulus upper surface has been uniformly arranged in the circumferential direction multiple engaging tooths, shaft is provided with by bearing rotation on shell, first gear is provided in shaft, first gear is meshed with the tooth on the upper surface of annulus, and the end of shaft is provided with turntable.The device rotates turntable by gear drive, and driving first gear rotates, and the valve rod of belt wheel annulus and valve rotates together, to achieve the purpose that control valve.Because the number of teeth of ring gear is greater than the gear of first gear, turntable rotate one week then valve rod only can rotate lesser angle, therefore reach the aperture of precision control valve door, to control water flow, can have multiple measured values in single experiment.Simultaneously as driving form is gear drive, therefore, which is physically easier to perform and uses.
Description
Technical field
The utility model relates to a kind of to reduce the variation of water valve aperture using being driven between gear and reduce firmly mechanical
Water valve.
Background technique
At this stage, with the raising of precision manufactureing level, the use of gear is more and more common, and with technological level
Raising and product category increase, intensity and corrosion resistance have been sufficient for life and industrial demand.
When carrying out related experiment in hydraulic experiment room, especially when frictional head loss, reynolds experiment etc., need
Data under multiple flows, according to general water valve, it is a variety of to generate that flow is difficult to control, valve tension is difficult to be opened and closed etc.
Problem.Laboratory water valve is usually from water valve used in traditional family, though structure is simple, for required for hydraulic experiment
Control precision be lacking.Also, since in hydraulic experiment room, the use of water is mostly that the Water in Water Tank of single laboratory table follows
Ring not will cause the waste of water.Therefore, it is necessary to the more accurate and easier to control water valves of an energy, to meet student experimenting
Demand, to improve the accuracy and success rate of experiment.
Summary of the invention
The purpose of the utility model is to overcome deficiency in the prior art, water flow stream in a kind of solution hydraulic experiment is provided
The uncontrollable scheme of amount.
In order to solve the above-mentioned technical problem, it is achieved through the following technical solutions:
A kind of gear driven type water valve, including pipeline, are fixed on the shell of pipeline external, the valve being mounted on pipeline,
Annulus is provided on the valve rod of valve, annulus upper surface has been uniformly arranged in the circumferential direction multiple engaging tooths, has turned on shell by bearing
It is dynamic to be provided with shaft, first gear is provided in shaft, first gear is meshed with the tooth on the upper surface of annulus, the end of shaft
Portion is provided with turntable.
By rotating turntable, driving first gear is rotated, and the valve rod of belt wheel annulus and valve rotates together, to reach control
The purpose of valve processed.Because the number of teeth of ring gear be greater than first gear gear, turntable rotate one week then valve rod only can rotate it is smaller
Angle, therefore reach the aperture of precision control valve door, to control water flow.Structure is simple, easy to operate.Shell is to tooth
Wheel portion carries out necessary protection, prevents foreign matter from entering and gear accidental damage.
It is further improved, the both ends of the pipeline are provided with external screw thread, convenient for connecting with other seals for pipe joints.
It is further improved, the shell is rectangular frame, is fixed by welding on pipeline.
It is further improved, the upper surface of the annulus is provided with tapered teeth, and first gear is angular wheel.
It is further improved, the annulus upper surface number of teeth is 5 times of the first gear number of teeth.
Compared with prior art, the utility model has the beneficial effects that
The device rotates turntable by gear drive, and driving first gear rotates, and the valve rod of belt wheel annulus and valve is together
Rotation, to achieve the purpose that control valve.Because the number of teeth of ring gear is greater than the gear of first gear, turntable rotates one week then valve
Bar only can rotate lesser angle, therefore reach the aperture of precision control valve door, to control water flow, single experiment can
To there is multiple measured values.Simultaneously as driving form is gear drive, therefore, which is physically easier to perform and uses.Relative to
Past simple water valve control, gets rid of and is forced to carry out to carry out the measurement under a variety of pipe stream flows when carrying out hydraulic experiment
The puzzlement of duplicate measurements.
Detailed description of the invention
Fig. 1 is a kind of main view of gear driven type water valve of the utility model.
Fig. 2 is the top view of Fig. 1.
Specific embodiment
The utility model is described in further detail with specific embodiment with reference to the accompanying drawing:
Fig. 1, shown in 2, a kind of gear driven type water valve, including pipeline 1 is fixed on the shell 2 of pipeline external, is mounted on pipe
Valve 5 on road is provided with annulus 7 on the valve rod of valve, and 7 upper surface of annulus has been uniformly arranged in the circumferential direction multiple engaging tooths, shell
Shaft 6 is provided with by bearing rotation on body 2, is provided with first gear 3 in shaft, on the upper surface of first gear 3 and annulus 7
Tooth be meshed, the end of shaft 6 is provided with turntable 4.
The device rotates turntable by gear drive, and driving first gear rotates, and the valve rod of belt wheel annulus and valve is together
Rotation, to achieve the purpose that control valve.Because the number of teeth of ring gear is greater than the gear of first gear, turntable rotates one week then valve
Bar only can rotate lesser angle, therefore reach the aperture of precision control valve door, to control water flow, single experiment can
To there is multiple measured values.Simultaneously as driving form is gear drive, therefore, which is physically easier to perform and uses.Relative to
Past simple water valve control, gets rid of and is forced to carry out to carry out the measurement under a variety of pipe stream flows when carrying out hydraulic experiment
The puzzlement of duplicate measurements.
In the present embodiment, the both ends of the pipeline 1 are provided with external screw thread, convenient for connecting with other seals for pipe joints.
In the present embodiment, the shell 2 is rectangular frame, is fixed by welding on pipeline.
In the present embodiment, the upper surface of the annulus 7 is provided with tapered teeth, and first gear 3 is angular wheel.
In the present embodiment, the 7 upper surface number of teeth of annulus is 5 times of 3 number of teeth of first gear.
Undeclared part involved in the utility model is same as the prior art or is realized using the prior art.
