Said invention utilizes the control valve to control water intake and discharge in valve body, and utilizes the pressune difference produced by inner and outer sides of valve core to implement movement of valve core so as to drive valve plug to open or close reservoir outlet. It has no need of large power or energy source. Its structure is simple and operation is convenient.
Description
The present invention relates to the hydraulic engineering field, specifically a kind of water discharge implement for reservoir.
We know that gate is a key device in the reservoir engineering field, and it generally is made up of door body, guide rail, lifting gear etc., and lifting gear adopts pulley or screw mandrel lifting more, finish by dynamic power machine, and the equipment manufacturing cost height starts complexity, big energy-consuming.Patent 87213231 has provided a kind of water discharge implement for reservoir, and it is made up of pedestal, door closure, stay cord, operating mechanism etc., and this device is fixed on the culvert pipe of reservoir bottom, replaces existing inclined tube, and its operating mechanism still needs exterior power; Patent 92238987 discloses a kind of autocontrol valve, utilize the reservoir spillway road waterpower opening and closing valve mechanism, control reservoir spillway and retaining automatically, this device could use in the time of can only having enough water to overflow at the flood-relief channel of reservoir.
Purpose of the present invention is exactly in order to overcome above-mentioned the deficiencies in the prior art, provides a kind of simple in structure, easy to operate, utilizes the water discharge implement for reservoir of differential water pressures opening and closing reservoir drainage mouth.
For achieving the above object, a kind of water discharge implement for reservoir of the present invention, it is characterized in that reservoir drainage mouth corresponding position is provided with a tubular valve body, which is provided with water inlet and outlet pipe and control corresponding valve, be provided with spool in the valve body, the spool outer end is connected with the corresponding valve of outfall stifled, pass through by-pass valve control, utilize the pressure differential of the inside and outside two side hydraulic pressures generation of spool, realize moving of spool, and then drive the stifled unlatching of valve or close the reservoir drainage mouth.
The present invention utilizes the pressure differential of the inside and outside two side hydraulic pressures generation of spool by water inlet, draining in the control tubular valve body, realizes moving of spool, and then drives the stifled unlatching of valve or close the reservoir drainage mouth.That is to say by the control minor valve, finish the control of reservoir discharge water automatically, only depend on manpower just can finish, do not need big power and energy.
Also be provided with spring in the tubular valve body of the present invention,, close the reservoir drainage mouth to assist stifled outer the moving of spool and valve; Also can be provided with limit power switch in the tubular valve body, the active force that moves inwards when spool is during greater than its transition resistance, and limit power switch is opened automatically, and it is used to limit the initial motion of spool, accelerates the opening process of outfall.In addition, can also be provided with an atmospheric communicating pipe on the tubular valve body, make the valve body internal gas pressure keep normal pressure, help the unlatching of reservoir drainage mouth.
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present invention.
As can be seen from Figure 1, a kind of water discharge implement for reservoir of the present invention, it is in the culvert 1 of reservoir dam, and outfall 2 corresponding positions are provided with a tubular valve body 3, and tubular valve body 3 can be stainless steel tube, also can be pipe of cement.Tubular valve body 3 is provided with water inlet 4 and outlet pipe 8 and control corresponding valve 5,9, is provided with spool 6 in the valve body, can be provided with sealing ring around the spool 6.Spool 6 outer ends are connected with outfall 2 corresponding valves and block up 7, and they can be processed as one.
When the present invention used, at first, by-pass valve control 5 and by-pass valve control 9 were in the opening and closing state respectively, at this moment, had identical hydraulic pressure inside and outside the valve body 3, because spool 6 inboard areas are greater than outside area, the outside active force of spool 6 is big, the stifled closed condition that is in of valve.When opening by-pass valve control 9, closing control valve 5, at this moment, water in the valve body flows out, and hydraulic pressure descends gradually, and the inside and outside differential water pressures of valve body progressively increases, when differential water pressures reaches spool 6 active force inwards greater than outside active force, stifled 7 beginnings of spool 6 and valve motion inwards, outfall is unlocked, and rests at last on the equilbrium position, finish opening process, reservoir is in hull-borne.When opening by-pass valve control 5, closing control valve 9, at this moment, in the current inlet valve body 3 in the reservoir, hydraulic pressure in the valve body rises gradually, and the differential water pressures inside and outside the valve body is progressively approaching, because spool 6 inboard areas are greater than outside area, when differential water pressures reaches the outside active force of spool 6 greater than inwards active force, outwards motion of stifled 7 beginnings of spool 6 and valve, outfall progressively is closed, and finally is in closed condition.The present invention utilizes the pressure differential of the inside and outside two side hydraulic pressures generation of spool by water inlet, draining in the control tubular valve body, realizes moving of spool, and then drives the stifled unlatching of valve or close the reservoir drainage mouth.That is to say by the control minor valve, finish the control of reservoir discharge water automatically.The bore of valve inleting water mouth 4 of the present invention and its outlet pipe 8 and the size of reservoir drainage mouth do not have direct relation, therefore, in the actual design, their bore is desirable very little, generally is no more than 30 centimeters, like this, by-pass valve control 5 and by-pass valve control 9 can adopt various ways, as: can be electromagnetic valve, also can the Artificial Control valve, only depend on manpower just can finish, do not need big power and energy.
Outlet pipe 8 of the present invention can be directly arranged on spool 6 and the valve stifled 7, that is to say in spool 6 and valve stifled 7 to be provided with the limbers, correspondingly establishes by-pass valve control on valve is stifled, substitutes above-mentioned outlet pipe 8 and by-pass valve control 9.
Also be provided with spring 10 in the tubular valve body 3 of the present invention,, close the reservoir drainage mouth to assist spool 6 and valve stifled 7 outer moving, certainly, the outfall opening process, differential water pressures is wanted enough greatly, with against the force of the spring etc.; Also can be provided with limit power switch 11 in the tubular valve body 3, it can be a snap switch, is arranged on spool guide peg 12 tail ends, the active force that moves inwards when spool 6 is during greater than its transition resistance, limit power switch is opened automatically, and it is used to limit the initial motion of spool, accelerates the opening process of outfall.Also be provided with spool guide peg 12 and guide peg gripper shoe 13 in the tubular valve body 3 of the present invention, with normal the moving that guarantees that spool and valve are stifled.In addition, can also be provided with an atmospheric communicating pipe 14 on the tubular valve body 3 of the present invention, its effect is to make the valve body internal gas pressure keep atmospheric pressure, helps the unlatching of reservoir drainage mouth.
The present invention is simple in structure, and is easy to operate, and by the control minor valve, the pressure differential of utilizing inside and outside two side hydraulic pressures of spool to produce realizes moving of spool, finishes the control of reservoir discharge water automatically, only depends on manpower just can finish, and does not need big power and energy.
