Description
Technical field
The present invention relates to the technical field of dam sealing corollary apparatus and replacing Bottom Sutlet bypass filling valve method, is a kind of Bottom Sutlet bypass pipe water inlet ball sealer and Bottom Sutlet bypass valve replacing options.
Background technology
As shown in Figure 2, the left side of dam 7 is catchment, right side is the district that discharges water, the inside of dam 7 is provided with Bottom Sutlet Emergency Gate 14, bottom outlet steel lining 13 is had on the right side of Bottom Sutlet Emergency Gate 14, the bypass pipe 8 of connected set pool and bottom outlet steel lining inside is had from the left side of dam 7 to bottom outlet steel lining 13, bypass pipe 8 on the right side of dam 7 is installed with the bypass filling valve 11 of shutoff bypass pipe 8, bypass filling valve 11 place above bottom outlet steel lining 13 is installed with gallery 10, makes bypass filling valve 11 handled easily and maintenance in gallery 10.Must to water-filling in bottom outlet steel lining 13 before unlatching Bottom Sutlet Emergency Gate 14, Bottom Sutlet Emergency Gate about 14 hydraulic balance can be made in water-filled bottom outlet steel lining 13, to open in hydrostatic or to close Bottom Sutlet Emergency Gate 14, thus reduction Bottom Sutlet Emergency Gate 14 is opened or closing presure.The general bypass pipe 8 that passes through is to water-filling in bottom outlet steel lining 13, but when winter temperature is too low, be very easy to enter cold air in gallery 10, because bypass filling valve 11 does not do any Insulation in design, be easy to cause the bursting by freezing of bypass filling valve 11 valve body to leak, by current storehouse water grid DEM, water level is higher than bypass valve water inlet pipe mouth about 37 meters, as calculated, if valve body breaks the 3000m that will have an appointment completely under current flow action
3the swelling of/h enters gallery 10, seriously jeopardize grouting human life safety in gallery 10, and cause scope in the gallery 10 of value more than 1,000 ten thousand in gallery 10 not had by water logging, also can cause huge obstacle for post-processed work in gallery 10 simultaneously, its loss is unpredictable, but bypass filling valve 11 is owing to not easily changing with hydraulic pressure.
Summary of the invention
The invention provides a kind of Bottom Sutlet bypass pipe water inlet ball sealer and Bottom Sutlet bypass valve replacing options, overcome the deficiency of above-mentioned prior art, it effectively can solve the damage of Bottom Sutlet bypass filling valve and not easily change problem.
One of technical scheme of the present invention is realized by following measures: a kind of Bottom Sutlet bypass pipe water inlet ball sealer comprises ball; Hanger is fixed with on the surface of ball.
Here is the further optimization and/or improvements to one of foregoing invention technical scheme:
The ball surface of the other end of above-mentioned corresponding hanger can be fixed with suspension ring, and the ball surface between hanger and suspension ring is fixed with layback ring.
The surface of above-mentioned ball can be fixed with one deck soft rubber.
Above-mentioned ball can be hollow steel ball.
Two of technical scheme of the present invention is realized by following measures: a kind of Bottom Sutlet bypass valve replacing options using Bottom Sutlet bypass pipe water inlet ball sealer, carry out in the steps below: the first step, first on dam facing, hoist engine is fixedly mounted, hanger on ball is fixedly connected with by wire rope with hoist engine, close bypass filling valve, then transfer Bottom Sutlet bypass pipe water inlet ball sealer and Bottom Sutlet bypass pipe water inlet ball sealer is positioned at the bottom outlet lock bypass pipe water inlet on the left of dam; Second step: build mounting platform in the gallery on the right side of dam, prepares new bypass filling valve; 3rd step, opens bypass filling valve, is drawn onto on bypass pipe water inlet by the strength of current by Bottom Sutlet bypass pipe water inlet ball sealer, because the pressure reduction of hydraulic pressure and air pressure makes Bottom Sutlet bypass pipe water inlet ball sealer by the shutoff of bypass pipe water inlet; 4th step, when the water leakage at bypass filling valve place obviously reduces, removes bad bypass filling valve, the bypass filling valve more renewed, and after replacing, is closed by new bypass filling valve and moves Bottom Sutlet bypass pipe water inlet ball sealer to dam facing by hoist engine.
Here is the further optimization and/or improvements to foregoing invention technical scheme two:
Above-mentioned transfer Bottom Sutlet bypass pipe water inlet ball sealer before, layback ring can fixedly mount the rope made of hemp, after opening bypass filling valve, the rope made of hemp first enters bypass pipe inside by the strength of current, and the end of the rope made of hemp flows out along the outlet of current from bypass pipe, then Bottom Sutlet bypass pipe water inlet ball sealer is drawn onto on bypass pipe water inlet by the strength of current, by in the shutoff of bypass pipe water inlet, now rope made of hemp end is fixed or fixed weight, make Bottom Sutlet bypass pipe water inlet ball sealer reliably by the shutoff of bypass pipe water inlet.
In the above-mentioned first step, Bottom Sutlet bypass pipe water inlet ball sealer to be positioned at the bottom outlet lock bypass pipe water inlet on the left of dam by Underwater Camera by Underwater Camera observation Bottom Sutlet bypass pipe water inlet ball sealer by operating personnel.
Above-mentioned wire rope can there is length mark.
Above-mentioned suspension ring can be installed with balancing weight.
Can arrange in gallery before the above-mentioned first step at least one block waterwall.
The present invention utilizes the pressure of water dexterously by the shutoff of Bottom Sutlet bypass pipe water inlet ball sealer on bypass pipe water inlet, thus can replacing bypass filling valve safely and fast, therefore the potential safety hazard changing valve is not only significantly reduced, avoid the generation of security incident, improve the operating efficiency changing valve, valve cost is changed in saving, also avoid in gallery the danger being worth up to ten million element device and incurring loss.
