Abstract
The invention relates to a water turbine with a cylinder valve sealed upper head face, which comprises a cylinder valve, a top cover, a sealing ring and a splint with L-shaped sections, wherein, the sealing ring and the external circle of a splint ring are a vertical side of the L shape, wherein, the height of the vertical side of the external circle of the splint ring is lower than that of the sealing ring; a ring-shaped groove is provided at the external circle corner of the bottom of the top cover; a plane part of the sealing ring contacts the upper plane of the ring-shaped groove at the bottom of the top cover; the vertical side of the sealing ring extends out of the external circle of the bottom of the top cover in the horizontal direction; the splint ring holds the sealing ring upwards and the two rings are fixedly connected inside the ring-shaped groove of the bottom of the top cover; a convex ring projecting to the direction of the circle center is arranged at the upper inner circle of the valve body of the cylinder valve; when the cylinder valve is closed downwards, the convex ring is connected with the vertical side of the sealing ring. As the water turbine adopts the L-shaped sealing ring and splint ring, the sealing requirements can be met, the sealing component is protected and the water flow is easy to conduct. In addition, a hexagon socket screw bolt is adopted for connection and embedded into the splint, thus ensuring that the screw bolt does not disturb the water flow in the flow passage.
Description
Technical field
The invention belongs to a kind of water turbine, particularly relate to a kind of water turbine that has the sealing of cartridge type valve upper-end surface.
Background technique
Because the particularity of water turbine cartridge type valve arrangement, existing various moulding sealings all can not be satisfied the seal request between cartridge type valve body upper-end surface and the top cover; Thereby cause in water turbine work, when needs cartridge type valve cuts out the shutdown of cut-out current, after the cartridge type valve cuts out, still the leakage current can be arranged between valve body upper end portion and the top cover.
Summary of the invention
The present invention provides a kind of water turbine that has the sealing of cartridge type valve upper-end surface that can satisfy seal request between cartridge type valve body upper-end surface and the top cover for solving the technical problem that exists in the known technology.
The technological scheme that the present invention takes for the technical problem that exists in the solution known technology is: it includes cartridge type valve and top cover, it also includes seal ring and the supporting plate ring that section configuration is the L type, described section configuration be the cylindrical of the seal ring of L type and supporting plate ring be the L type vertical projection on one side, and the cylindrical of supporting plate ring is that the seal ring cylindrical that the vertical projection height on one side of L type is lower than the L type is the vertical projection height on one side of L type; In described cap base cylindrical corner one section being arranged is rectangular annular groove; Described section configuration is that the upper horizontal plane that horizontal plane part and the described cap base section of the seal ring of L type is rectangular annular groove contacts, and stretches out described cap base cylindrical in the horizontal direction Yi Bian described section configuration is the vertical projection of the seal ring of L type; Described section configuration is that supporting plate ring and the described section configuration of L type is that the seal ring of L type contacts and upwards holds seal ring, and described seal ring and supporting plate ring together to be connected in described cap base cylindrical corner section be in the rectangular annular groove; Circle has a sealing bulge loop to center of circle direction protrusion in the valve body top of described cartridge type valve, and described sealing bulge loop can join the upper end on one side with the vertical projection of described seal ring when the cartridge type valve cuts out downwards.
The present invention can also adopt following technological scheme:
Between described seal ring and described top cover connecting part, also has the adjustment pad of adjustable whole decrement.
On the annular groove of described cap base, screw is arranged, porose on described seal ring, supporting plate ring and adjustment pad; Socket head screw is fixed to them in the screw on the described cap base annular groove by described seal ring, supporting plate ring and the hole adjusted on the pad; And described socket head screw head is to sink in the above the hole of described supporting plate ring.
Advantage and good effect that the present invention has are: owing to can adopt the anti-granule wearing and tearing of high-quality, L type stable performance, that elasticity is moderate sealing ring and supporting plate ring structure, thus can guarantee to satisfy seal request.So not only help protecting Sealing and better sealability is arranged, also help guiding simultaneously current, supporting plate ring and handle close nut and are stainless steel material simultaneously, have effectively guaranteed their working life.In addition because hexagonal nut linkage structure in adopting, and the nut head is embedded to supporting plate inside fully, guaranteed that not only nut is not washed away, and guaranteed that simultaneously nut does not disturb the runner streamflow regime.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
For further understanding content of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
As shown in Figure 1, section configuration is that the rubber seal ring 4 of L type, the supporting plate ring 5 and the red copper of adjustable whole decrement that section configuration is the L type are adjusted pad 3, is fixed on the top cover 2 with hexagonal nut 1 in the stainless steel.Be distributed with a plurality of screws on the annular groove of top cover 2 bottoms, the screw number that distributes on the annular groove of also relative top cover 2 bottoms on rubber seal ring 4, supporting plate ring 5 and the adjustment pad 3 has the same number of hole; Hexagon socket head cap screw 1 is fixed to them on the top cover 2 base circle grooves in the corresponding screw by seal ring 4, supporting plate ring 5 and the hole adjusted on the pad 3; And the bolt head of hexagon socket head cap screw 1 is in the hole of sinking on the supporting plate ring 5.
When cartridge type valve 6 cut out, the sealing bulge loop 7 on the cartridge type valve 6 and section configuration were that the vertical projection upper end on one side of the rubber seal ring 4 of L type contacts and compresses, thereby guarantee sealing effect.When cartridge type valve 6 was opened, rubber seal 4 and supporting plate ring 5 were included in cartridge type valve 6 body cavities all, do not influence streamflow regime, and stainless steel nut 1 all in wetted surfaces, does not influence fluidised form yet simultaneously.
Between rubber seal ring 4 and supporting plate ring 5, can not want red copper yet and adjust pad 3.Red copper adjustment pad 3 also can be made up of one or more pieces,
The material of rubber seal ring 4 can adopt the wearing and tearing of the anti-granule of high-quality, neoprene stable performance, that elasticity is moderate or other plastic materialss etc.
