Abstract
The utility model relates to a hydraulic structure one-way drain valve, which can be directly buried in the draining hole of a hydraulic structure. When the external water pressure is higher than the internal water pressure, the external water can be exhausted, and the external water pressure is reduced rapidity. When the internal water pressure is higher than the external water pressure, the reverse flow is cut off. The hydraulic structure one-way drain valve which is made of plastic can not be rusted. A valve core is convenient to disassemble and has a silt preventing function. The utility model has the advantages of simple burying, no corrosion and silt prevention, and is suitable for the draining of hydraulic structures for concrete or steel lining tunnels, the side walls and bottom boards of ship locks, etc.
Description
The utility model is a kind of single slope drainage valve that is used for hydraulic structure.
As everyone knows, with hydraulic structures such as the side wall of the tunnel of concrete or steel plate liner, ship lock or base plates, often be subjected to the effect of external water pressure in the country rock, when in these buildings when drawdown or emptying, because the effect of high external water pressure, the phenomenon of lining cutting or side wall damage, unstability often has generation.Therefore, when carrying out the design of above-mentioned hydraulic structure, need to consider higher outer water ballast(ing), cause the cost of building to increase.At this problem, the way that adopts usually referring to Fig. 1, all is to be drilled with drain hole (1) on lining cutting or side wall at present, and nose end is established filtering material (2), to subdue water pressure outside the country rock.Though this way is simple, and following drawback is arranged: the one, the filtering material of drain hole is silted up by silt easily, and can not disassembly, cleaning, causes drain hole to lose efficacy.The 2nd, drain hole can only double drainage, can not unidirectional control draining, promptly when the country rock external water pressure is higher than the building internal water pressure, outer water is inwardly arranged, and when the building internal water pressure was higher than external water pressure, interior water oppositely effluxed, and this situation is disadvantageous in hydraulic structures such as pressure tunnel.
The purpose of this utility model is anti-to silt up for hydraulic structure provides a kind of, resistant to rust, be convenient to dismounting, can unidirectional control draining, to subdue the single slope drainage valve of hydraulic structure external water pressure rapidly.
The utility model is finished as follows: in the drain hole that hydraulic structure is drilled with, bury an one way valve that has sleeve pipe underground.Overlap effective method bonding or welding and be fixed on the drain hole hole wall, the spool part of being made up of valve body, cone valve, spring and valve seat is housed in the sleeve pipe.When the country rock external water pressure is higher than internal water pressure, length of spring compressed, cone valve is open, and outer water is inwardly arranged; When internal water pressure is higher than the country rock external water pressure, the cone valve sealing, reverse flow is cut off, and interior water can not efflux, and has so just realized unidirectional control draining.In addition, also done following consideration in configuration aspects, the one, the little permeable hole of the water inlet end of valve body for gathering, permeable not saturating sand can prevent silt particle silting spool; The 2nd, the outfall of valve seat is a hexagon in, is convenient to dismantle spool, and drain hole is carried out periodic flushing.Choose in material choosing, spool is partly with plastics or nylon manufacturing, spring stainless steel wire coiling, so the utility model uses under water and has good resistant tarnishing.
Owing to adopt above measure, therefore the utlity model has anti-ly silt up, resistant to rust, be convenient to dismantle, advantage that can unidirectional control draining, the external water pressure that can subdue hydraulic structure is to increase its degree of safety and to reduce its cost.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the conventional drain hole schematic diagram of hydraulic structure.
Fig. 2 is that the utility model is embedded in the sectional drawing in concrete lining or the concrete wall.
Fig. 3 is that the utility model is welded on the sectional drawing in the steel plate liner.
Fig. 4 is the little permeable hole schematic diagram of valve inleting water end.
Fig. 5 is valve seat delivery port figure.
Embodiment:
Referring to Fig. 2, the utility model is by sleeve pipe (6) and comprise that the spool of valve body (5), cone valve (3), spring (4) and valve seat (7) forms.One end of sleeve pipe (6) has water inlet (8), and the inwall of the other end has screw thread.Valve body (5) one end outer walls have screw thread to cooperate with sleeve pipe (6), and inwall has screw thread to cooperate with valve seat (7), and the little permeable hole of the close brill of the other end (9) of valve body (5) is with permeable filter sand.Cone valve (3) is drilled with water hole (10) on it in the cavity of valve body (5).Have delivery port (11) on the valve seat (7), delivery port (11) is made hexagon, so that dismounting, the periphery of valve seat (7) has screw thread to cooperate with valve body (5).Spring (4) is positioned between cone valve (3) and the valve seat (7) in the cavity of valve body (5).
Little permeable hole (9) is referring to Fig. 4; Delivery port (11) on the valve seat (7) is referring to Fig. 5.
Above-mentioned sleeve pipe, valve body, cone valve and valve seat plastic production, spring stainless steel wire coiling, therefore, the utility model uses under water has good resistant to rust ability.
Installation steps of the present utility model, referring to Fig. 2, at first on concrete lining or concrete wall surface, bored drain hole (1) with air drill, after with water under high pressure drain hole (1) being rinsed well, with bonding agent sleeve pipe (6) is bonded on the hole wall, then valve body (5) is screwed in sleeve pipe (6), the cone valve (3) of packing in turn again, spring (4) are spun on valve seat (7) on the valve body (5) at last.When the country rock external water pressure was higher than internal water pressure, the country rock infiltration entered spool by water inlet (8) and little permeable hole (9), because the permeable filter sand effect of little permeable hole (9), silt particle is hindered in the spool outside.Under the effect of water pressure, spring (4) compresses outside, and cone valve (3) is open, and current are discharged by delivery port (11) at last through water hole (10).External water pressure is subdued.Otherwise when internal water pressure was higher than the country rock external water pressure, spring (4) was upheld, cone valve (3) sealing, and reverse flow is cut off.Like this, unidirectional control draining is achieved.
Referring to Fig. 3, for the situation with steel plate liner, sleeve pipe of the present utility model (6) can be made of steel, so that sleeve pipe is welded in the steel plate liner easily.
