Description
Technical Field
The utility model belongs to the technical field of the valve, specific saying relates to a apron formula prevents long-pending check valve of silt.
Background
In water conservancy projects such as lined channels, reservoirs, dams with subsurface flows and the like, a channel drainage system is required to reduce uplift pressure of underground water on a lining structure to ensure stability of the lining structure, freezing expansion is easily caused to damage the lining structure if pressure cannot be timely reduced in the north in winter, and the existing channel underground water pressure relief construction mostly adopts a method of combining underground pipe water permeation and ground check valve drainage.
The utility model discloses a utility model patent that the bulletin number is CN207406842U discloses an all-round adjustable pressure prevents that long-pending apron formula prevents long-pending check valve that becomes silted up, and the structure that constitutes this check valve includes the thin barrel that bottom and infiltration pipeline are connected and rather than the thick barrel that the top is connected through annular disc, and the fixed bearing end cover of screw thread or rotatory block is passed through at the top of thick barrel, sets up movable sealed apron in the thick barrel, sets up pressure regulating spring between bearing end cover and the sealed apron, is used for sealing delivery port and outlet on the annular disc. The working principle is as follows: the compression pressure regulating spring at the lower part of the pressure-bearing end cover presses the sealing cover plate to seal the water outlet and the water outlet on the annular disc, so that flowing water discharged from the outside is prevented from carrying silt to flow back into the valve body, and when the groundwater uplift pressure is greater than the pressure of the pressure regulating spring, the sealing cover plate is pushed upwards to be discharged from the water outlet on the annular disc. However, because the water outlet forming the check valve is arranged on the annular disc, a compressed air cavity formed in the top of the pressure-bearing end cover is smaller, namely, water with sand flowing back into the pressure-bearing end cover and the space at the top of the end cover are extremely small, so that formed sludge can almost fill the space formed by the pressure-bearing end cover and the thick cylinder body, and the spring is buried to cause the failure of the water stop valve.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a can effectively reduce the silt entering of thick barrel, avoid the spring to be buried by silt and die the apron formula that leads to its inefficacy and prevent long-pending check valve.
In order to achieve the above object, the utility model adopts the following technical scheme:
a cover plate type siltation-proof check valve comprises a cylinder body, the bottom of the cylinder body can be connected with a water seepage pipeline, the top of the cylinder body is provided with an annular disc, the inner ring of the annular disc is provided with a water outlet, the outer ring of the annular disc is provided with a water outlet, the annular disc is provided with a pressure-bearing end cover which is matched with the annular disc, a cavity structure is formed between the pressure-bearing end cover and the annular disc, the annular disc is provided with a movable sealing cover plate, and a pressure-regulating spring is arranged between the pressure-bearing end cover and the sealing cover plate and used for sealing the water outlet; it is characterized in that a ring cylinder mechanism is arranged on the outer side of the water discharging port on the ring-shaped disc.
The additional technical characteristics that constitute above-mentioned apron formula silt prevention check valve still include:
-said ring cylinder is integral with said annular disc;
the ring cylinder and the pressure-bearing end cover are of an integral structure, namely, a wing edge of the pressure-bearing end cover is formed;
a large ring mechanism capable of being in screwed or socket-and-spigot sealing connection with the pressure-bearing end cover is arranged on the annular disc.
The utility model provides a cover plate type siltation-proof check valve compares with prior art, because the outside of the mouth of a river is provided with a ring section of thick bamboo mechanism on the annular disc that constitutes the check valve, this ring section of thick bamboo can be so that the water pressure increase in the cavity structure that forms between annular disc that is provided with pressure regulating spring and pressure-bearing end cover promptly, consequently can reduce the inflow, increase anhydrous space, reduced silt promptly to pressure regulating spring's siltation, guaranteed pressure regulating spring's validity, prolonged its long service life.
Drawings
Fig. 1 is a schematic structural view of a cover plate type siltation prevention check valve provided by the present invention;
fig. 2 is a schematic structural diagram of another cover plate type anti-silting check valve.
Detailed Description
The structure and the working principle of the cover plate type siltation prevention check valve provided by the present invention will be further described in detail with reference to the accompanying drawings.
As shown in fig. 1, the cover plate type siltation prevention check valve provided by the present invention has a schematic structural view. The structure of the check valve comprises a cylinder body 1, the bottom of which can be connected with a water seepage pipeline 12, an annular disc 8 is arranged at the top of the cylinder body, a water outlet 7 for discharging underground water is arranged in a cylinder ring of the annular disc, a water outlet 2 for discharging the underground water out of the cylinder body is arranged outside the cylinder ring, a sealing cover plate 5 for sealing the water inlet and the water outlet to prevent the water inlet and the water outlet from flowing backwards and a pressure-bearing end cover 4 matched with the sealing cover plate and forming a cavity structure 3 between the sealing cover plate and the sealing cover plate are arranged on the annular disc, a pressure-regulating spring 6 is arranged between the pressure-bearing end cover plate and the sealing cover plate, and an annular.
The working principle is as follows: because the outside of the water discharging opening on the annular disc is provided with the annular cylinder 9, the pressure in the cavity 3 is increased by the water discharging opening, and meanwhile, the air space 31 formed by the upper part is increased due to the increase of the water pressure of the water in the cavity, so that the sludge entering the space along with the water discharging opening is greatly reduced, the effectiveness of the pressure regulating spring 6 is ensured, and the service life of the water stop valve is prolonged.
In addition, as shown in fig. 2, when the ring cylinder 9 and the pressure-bearing end cover 4 form an integral structure, namely, the wing edge of the pressure-bearing end cover is formed and is also lower than the annular disc provided with the water outlet and the water drain hole, the formed cavity 31 is enlarged, the water level in the cavity is reduced, the spring exposed to the water surface is lengthened, the effectiveness of the pressure-regulating spring 6 is also ensured, and the service life of the water stop valve is prolonged;
in the structure of the check valve shown in fig. 1 and 2, the large ring 10 capable of being screwed or socket-sealed with the pressure-bearing end cover is arranged on the annular disc, so that the manufacture, installation and repair are more convenient.
