Description
Technical field
The utility model relates to hydraulic and hydroelectric engineering technical fields, more particularly, to a kind of silting blocking boxlike of pulley drive
Flap valve filling valve.
Background technique
Emergency gate and bulkhead gate in China's hydroelectric project are generally hydrostatic and open door, and opening needs to put down to water-filling behind the door in front of the door
Pressure.Currently, the mode for the gate water-filling concora crush applied at home is mainly include the following types: bypass valve type, Men Shangshe filling valve, small
Aperture proposes the patterns such as door, gate internode water-filling, and various concora crush modes have the characteristics that its different and applicable elements.
1, by-passing valve water-filling: by-passing valve is set in dam body or in the gate pier of intake gate, and the library water before gate passes through bypass
Valve is flow to behind gate, and water flow is controlled by pipeline gate valve, generally sets twice valve in valve chamber, before for maintenance gate valve, behind be work
Make gate valve, operating platform is set in corridor in dam or gate pier top surface.This concora crush mode, which has, simplifies log type gate leaf, and diameter
The characteristics of selection is not limited by log type gate leaf, but there is also cost height, operation inconvenient maintenance, it overhauls gate valve and gate valve preceding pipeline is tight
Corrosion is difficult to the disadvantages of overhauling security risk brought by replacement again.2, small guide vane mentions a water-filling: this water-filling mode is suitable for hole
Mouth diameter is smaller, the lesser gate of head, and when arrangement filling valve difficulty, but this water-filling mode cannot reduce headstock gear appearance
Amount, and the small guide vane overcurrent having can make gate generate vibration, and gap jet stream also will cause the cavitation erosion etc. of hydraulic structure,
Therefore general less use.3, gate internode water-filling: this water-filling mode is often made a slip of the tongue using formation hole at the merogenesis up and down of gate
Stream, the water-filling section of this mode is big, can shorten the filling time, and structure is simple, and operation is easy to maintenance, is not required to set water-filling
Valve；Due to only putting on section door when water-filling, so the increase of headstock gear capacity is less, headstock gear lift, but this water-filling side are not increased yet
Formula is applied on low water head gate more.4, Men Shangshe filling valve water-filling: the structure type of this water-filling mode is more, works as gate sealing
When for preceding sealing, wicket is opened on gate or sets filling valve, this structure is more complex；When gate is rear sealing, then on door
If charging pipe and valve body (or valve deck)；The operation of filling valve should link with gate hoist, and the diameter of charging pipe should be according to water-filling
Amount and filling time etc. are because usually determining.This water-filling mode is because operation maintenance is more convenient, so using relatively wide.
There are commonly gland-types, plunger-type structure for filling valve, under the conditions of low water head and clear water, mainly use traditional pressure
Lid formula or plunger type filling valve carry out the water-filling concora crush of gate.Gland-type is generally used for downstream backwater gate, and traditional gland-type
Filling valve only sets one of ring-shaped rubber or rectangle p-type water seal, if there are silt or other foreign matters on door top, will lead to filling valve closing
Imprecision and drainage occurs, the more aobvious protrusion especially in high pressure gate, head is higher, and water leakage is bigger；In addition, water-filling
Valve shaft will lead to valve body and the friction of only collar be serious, and steel to steel coefficient of friction is very big, leads sometimes to using only collar limit
It causes filling valve that can not close, influences the operation of gate water blocking and there are security risks, so state of the art is perfect not enough.?
When high water head, Gao Hansha and multi-state service condition, there are silt silting, spool card resistance, valve bodies to corrode for traditional filling valve, fills
The problems such as water valve leak and difficult maintenance.
Summary of the invention
Spool card resistance can be caused to can not work normally because silt, dirt and aquatic organism influence to solve traditional filling valve
The problem of, under the conditions of can adapt to different reservoir levels and igfet gate the purpose of the utility model is to provide one kind, not by mud
Sand influences, and sealing is reliable, repair and maintenance amount is small, the silting blocking boxlike flap valve filling valve of economical and practical pulley drive.
