Description

Prevent leaking gate water filling valve

Technical Field

The utility model relates to a prevent leaking gate water filling valve.

Background

The emergency gate is a gate used in an accident at the downstream (or upstream) of a building opening. To prevent the spread of accidents, such gates generally require that the orifice be closed to shut off the flow of water under flowing water conditions. After the accident clears, the orifice can then be opened under still water conditions. Accidents often require rapid closing of the orifice, and so may be referred to as rapid gates; in water conservancy and hydropower engineering, in order to effectively reduce the opening force of an access door and avoid adverse effects caused by high-speed water flow impacting a water guide mechanism of a working door or a water turbine in a short time of opening the door, a door section or a water conveying pipeline is usually filled with water before the access door or an accident door is opened so as to balance the water pressure at two sides of the access door or the accident door; for this purpose, a filling valve is usually provided on the respective sluice. At present, a water filling valve structure which is frequently adopted is a flat pressure mode, the water filling valve structure is linked with a gate hoist through a lifting lug and a lifting rod, and a travel switch with a small opening degree is arranged on the hoist, so that the water filling valve can be opened through the hoist to fill water. The structure of the water filling valve is generally divided into three types, namely a flat cover type, a gate valve type and a plunger type, and the water filling valve is comprehensively designed according to the water filling volume, the water leakage amount, the water filling time, the designed water head, the gate water stopping mode and the like.

In the closing process of the existing water filling valve, water flow can generate certain floating force on a descending gland, so that a valve core is not firmly closed, the water leakage condition of the water filling valve can occur, displacement deviation and a plurality of water leakage conditions also exist due to the fact that a plurality of valve cores are subjected to horizontal impact force of water, and the water inflow cannot be adjusted.

Fig. 1 is a schematic structural diagram of the present invention;

in the figure: the water-saving valve comprises a water inlet pipe 1, a water inlet 11, a water outlet 2, a valve core 3, a mounting plate 31, a sealing gasket 32, a plug 4, a water outlet 41, a connecting block 5, a pull rod 6, a pull box 7 and a plane gate 8.

Detailed Description

The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.

A water filling valve of a leakproof gate is used in a plane gate 8 of water conservancy and hydropower engineering and comprises a valve body; the upper and lower both ends of valve body set up respectively into inlet tube 1 and outlet pipe 2, install case 3 and end cap 4 in the inlet tube 1, case 3 covers end cap 4 in case 3 when the valve is closed, it seals to process delivery port 41 on end cap 4, the route of filling of shutoff inlet tube, case 3 is connected with drawing case 7 through even pull rod 6, when the flat pressure that fills water needs, draw case 7 pulling pull rod 6, mention case 3 upwards, make case 3 and end cap separation, the water inlet of end cap upper end begins to intake, the inlet tube switches on and fills water to the gate rear end.

Furthermore, a water inlet 11 is processed on the side wall of the water inlet pipe 1, and a plurality of grids along the axial direction of the water inlet pipe 1 are arranged at the water inlet 11. The water inlet ring valve core 3 is arranged, so that the pressure received by each direction of the valve core is balanced, the damage caused by the long-term overlarge pressure in a certain direction of the valve core is prevented, the valve is prevented from leaking, and the opening size of the water inlet 11 can be adjusted by controlling the stroke of the valve core 3 in the upward lifting process of the valve core 3 due to the fact that the outer wall of the valve core 3 is attached to the inner wall of the water inlet pipe 1, so that the water filling speed can be adjusted.

Further, end cap 4 is the barrel that toper and cylinder combine, and the cylinder barrel sets up in the upper end, and processing has delivery port 41 on the lateral wall of cylinder barrel, and the end cap lower extreme is main sealed terminal surface, sets up to the toper of toper and case and combines, and the water inlet has certain pressure to the case when closing, makes the laminating of case and end cap conical surface inseparabler, and sealed effect is better.

Furthermore, the water outlets 41 are grids along the axial direction of the plugs 4, so that the water filling flow can be adjusted in the separation process of the valve core and the plugs.

Furthermore, the upper end face of the valve core 3 is fixedly connected with the mounting plate 31 through a bolt, the center of the top end of the mounting plate 31 is fixedly connected with the connecting block 5, the connecting block 5 is fixedly connected with the pull rod 6 through a bolt, the shape of the inner wall of the valve core 3 is the same as that of the outer wall of the plug 4, the inner wall of the valve core 3 is completely covered by the sealing gasket 32, so that the valve core can be replaced and maintained when damaged, and a layer of sealing rubber gasket covers the inside of the valve core, so that the valve core and the plug are prevented from being worn due.
