Description
Technical field
This utility model relates to a kind of water pipeline regulation valve.
Background technology
Regulation valve has another name called control valve, by accepting the control signal of regulation unit output, goes to change fluid flow by power operation.Regulation valve is typically made up of actuator and valve.If the power used by its joined actuator, regulation valve can be divided into pneumatic control valve, electric control valve, hydraulic adjusting valve three kinds, it addition, divide by its function and characteristic, linear characteristic, and equal percentage characteristics and parabolic characteristic three kinds.Air bladder regulating valve of two-seater, two valve seats are had in pneumatic diaphragm control valve valve body, fluid is gone out by the upper-lower seal surface current of spool, and out-of-balance force is little, is a kind of balance type structure, pneumatic diaphragm control valve allows to use pressure reduction bigger, being applicable to pressure reduction big, pneumatic diaphragm control valve flow is big, and leakage rate requires the occasion not being strict with, pneumatic diaphragm control valve be widely used in oil, chemical industry, pharmacy, metallurgy, power station, etc. industrial department, control the medium such as gas, liquid, steam.
Pneumatic diaphragm control valve is made up of pneumatic diaphragn actuating mechanism and regulation valve two large divisions, it and air-operated controller, and air relief valve, localizer or other instrument are with the use of, the technological parameter such as the temperature that reaches to control in pipeline, pressure, liquid level, flow.Single-seat adjusting valve has easily sealing, the advantage that leakage rate is little, but equilibrant is relatively big, therefore operting differential pressure is unsuitable too high.It is big that regulating valve of two-seater has discharge coefficient, the feature that out-of-balance force is less, thus uses extensively.
Current existing water pipeline regulating valve structure is simple, and structural stability is poor, is not suitable for the regulation of large-scale pipeline.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of easy to operate, and structural stability is high, is suitable for the water pipeline regulation valve of the runoff investigation of large-scale pipeline.
For solving the problems referred to above, this utility model adopts the following technical scheme that a kind of water pipeline regulation valve, including valve head, square plate and valve body, described valve head and square plate are arranged on valve body, it is provided with diaphragm in described valve head, described diaphragm is tightly connected with valve head, in the middle part of described diaphragm, push rod is installed, it is provided with spring on described push rod, described push rod one end is hinged with square plate, pole and connecting rod it is provided with on described square plate, described square plate respectively with pole and rod hinge connection, described pole is fixedly connected with the valve body, described connecting rod lower end is provided with valve rod, described valve rod and rod hinge connection, it is provided with filler chamber on described valve body, described valve rod is located in the middle part of filler chamber.
As preferably, in described valve body, it is provided with valve seat.
As preferably, described valve stem end is provided with spool.
As preferably, described spool and valve seat are in being correspondingly arranged.
As preferably, described valve body two ends are provided with flange.
The beneficial effects of the utility model are: the diaphragm in the valve head of setting can drive push rod to move right under the extruding of gases at high pressure, push rod drives square plate skew, connecting rod band ovable valve stem is moved down, thus regulate flow, the kind of drive using square plate and connecting rod can keep structural stability high, is suitable for large-scale pipeline；The spring arranged can keep push rod to automatically reset, keep easy to operate after the gas in valve head is discharged.
Accompanying drawing explanation
Fig. 1 is the structure chart of a kind of water pipeline of this utility model regulation valve.
Detailed description of the invention
As shown in Figure 1, a kind of water pipeline regulation valve, including valve head 1, square plate 2 and valve body 3, described valve head 1 and square plate 2 are arranged on valve body 3, it is provided with diaphragm 4 in described valve head 1, described diaphragm 4 is tightly connected with valve head 1, in the middle part of described diaphragm 4, push rod 5 is installed, it is provided with spring 6 on described push rod 5, described push rod 5 one end is hinged with square plate 2, pole 7 and connecting rod 8 it is provided with on described square plate 2, described square plate 2 is hinged with pole 7 and connecting rod 8 respectively, described pole 7 is fixing with valve body 3 to be connected, described connecting rod 8 lower end is provided with valve rod 9, described valve rod 9 is hinged with connecting rod 8, it is provided with filler chamber 10 on described valve body 3, described valve rod 3 is located in the middle part of filler chamber 10.
Being provided with valve seat 11 in described valve body 3, valve seat 11 keeps Flow-rate adjustment convenient.
Described valve rod 9 end is provided with spool 12, by the gap i.e. regulating flow quantity of regulation spool 12 with valve seat 11.
Described spool 12 and valve seat 11 are in being correspondingly arranged.
Described valve body 3 two ends are provided with flange 13, and flange 13 keeps valve body easy for installation.
The beneficial effects of the utility model are: the diaphragm in the valve head of setting can drive push rod to move right under the extruding of gases at high pressure, push rod drives square plate skew, connecting rod band ovable valve stem is moved down, thus regulate flow, the kind of drive using square plate and connecting rod can keep structural stability high, is suitable for large-scale pipeline；The spring arranged can keep push rod to automatically reset, keep easy to operate after the gas in valve head is discharged.
The above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model is not limited thereto, any change expected without creative work or replacement, all should contain within protection domain of the present utility model.
