Description
Technical Field
The invention relates to the technical field of water conservancy and hydropower engineering, in particular to a four-way running arc gate water filling valve.
Background
Accident gates and maintenance gates in water and electricity engineering in China are normally static water opening gates, and water is filled behind the gates before opening the gates for flat pressing. At present, the gate horizontal pressure charging modes applied in China mainly comprise the following modes: the bypass valve type and the door are provided with a water filling valve, a small opening lifting door, water filling between the gate joints and the like, and various flat pressing modes have different characteristics and application conditions.
1. The bypass valve is filled with water: the bypass valve is arranged in the dam body or the gate pier of the water inlet gate, the reservoir water in front of the gate flows to the rear of the gate through the bypass valve, the water flow is controlled by the pipeline gate valve, two valves are generally arranged in the valve chamber, the front of the valve chamber is provided with the maintenance gate valve, the rear of the valve chamber is provided with the working gate valve, and the operating platform of the valve chamber is arranged in the gallery of the dam body or the top surface of the gate pier. The flat pressing mode has the characteristics of simplifying the door leaf structure, and the diameter selection is not limited by the door leaf structure, but has the defects of high manufacturing cost, inconvenient operation and maintenance, difficult maintenance and replacement due to serious rust on the gate valve and the front pipeline of the gate valve, and the like. 2. And (3) water filling of the small opening lifting door: the water filling mode is suitable for gates with smaller orifice diameter and smaller water head, and when water filling valves are difficult to arrange, but the water filling mode cannot reduce the capacity of a hoist, and the gates vibrate due to small-opening overcurrent, and cavitation damage and the like of hydraulic buildings are caused by gap jet flow, so that the water filling mode is generally less adopted. 3. Water filling between gate joints: the water filling mode often utilizes the orifice overflow formed at the upper and lower sections of the gate, the water filling section of the mode is large, the water filling time can be shortened, the structure is simple, the operation and the maintenance are convenient, and a water filling valve is not needed; because only the throttle is lifted during water filling, the capacity of the hoist is increased less, and the lift of the hoist is not increased, but the water filling mode is mostly applied to a low-head gate. 4. A water filling valve is arranged on the door to fill water: the water filling mode has more structural forms, when the water stop of the gate is the front water stop, a small gate is opened on the gate or a water filling valve is arranged on the gate, and the structure is more complex; when the gate is a rear water stop, a water filling pipe and a valve body (or a valve cover) are arranged on the gate; the operation of the water filling valve is linked with the gate hoist, and the diameter of the water filling pipe is determined according to the factors such as water filling amount and water filling time. The water filling mode is convenient to operate and maintain, so that the application is wider.
The water filling valve is commonly provided with a gland type structure and a plunger type structure, and under the conditions of low water head and clean water, the water filling flat pressure of the gate is mainly carried out by adopting a traditional gland type or plunger type water filling valve. The gland type water filling valve is generally used for a downstream water stopping gate, while the traditional gland type water filling valve is only provided with an annular rubber or rectangular P-type water seal, if sediment or other foreign matters exist on the top of the valve, the water filling valve is not tightly closed and water leakage phenomenon occurs, and particularly the water filling valve is more prominent in a high water head gate, and the water leakage amount is larger when the water head is higher; in addition, the water filling valve axially adopts the stop collar limit, so that the valve body and the stop collar are seriously rubbed, the friction coefficient of steel to steel is very large, the water filling valve can not be closed sometimes, the water retaining operation of a gate is influenced, and the potential safety hazard exists, so the prior art is not perfect. Under the running conditions of high water head, high sand content and multiple working conditions, the traditional water filling valve has the problems of silt blockage, valve core blocking, valve body corrosion, water leakage of the water filling valve, difficult maintenance and the like.
