Abstract
The utility model discloses a kind of water conservancy civil engineering single slope drainage exhaust valves, including episphere, four part of lower semisphere, hose and protection cap；The episphere is connected with lower semisphere by bolt, and the hose is extracted out from the exit on episphere top, and the top of the episphere is equipped with a protection cap；It is uniformly distributed on the lower semisphere to have drainage stomata, and geotextiles are filled in the episphere and lower semisphere.Compared to existing single slope drainage valve, the utility model has better degassing function, and is not easy to plug.The utility model uses filtration material, can effectively cross the grains of sand in drainage, it is only necessary to which upper and lower two hemispheres are fixed, and structure is simple.
Description
Technical field
The utility model relates to valve mechanism fields, and in particular to a kind of water conservancy civil engineering single slope drainage exhaust valve.
Background technique
Currently, well known reservoir bottom single slope drainage valve is all flat lid type drain valve, bottom storehouse layer of sand water body pressure will be unidirectional
Valve top cover opens, and water body flows into library.But such check valve, there are drawback, reservoir bottom grains of sand mud, which enters in drainpipe, to be easy
Blockage will be drained, makes to drain defective valve, in addition, such valve degassing function is poor.
Utility model content
To solve the above problems, the utility model provides a kind of water conservancy civil engineering single slope drainage exhaust valve and its arrangement
Method can effectively avoid grains of sand mud from blocking check valve, and have preferable degassing function.Traditional single slope drainage valve can effectively be avoided
Shortcoming.
To achieve the above object, the technical solution that the utility model is taken are as follows:
Water conservancy civil engineering single slope drainage exhaust valve, including episphere, four part of lower semisphere, hose and protection cap；
The episphere is connected with lower semisphere by bolt, and the hose is extracted out from the water outlet pipe part on episphere top, the upper half
The top of ball is equipped with a protection cap；It is uniformly distributed on the lower semisphere to have drainage stomata, and in the episphere and lower semisphere
It is filled with geotextiles.
Further, the episphere and lower semisphere include hemisphere and to be mounted on hemisphere open end outer peripheral
Outer ring offers the bolt hole matched on two outer rings.
Further, a pilot pin, the tail end and 4 inner bottom surface of lower semisphere of the pilot pin are equipped in the lower semisphere at center
Center at it is affixed, the other end extends in episphere.
Further, the hose is extracted out from protection cap, and one end is connected in the outlet pipe on episphere top.
Compared to existing single slope drainage valve, the utility model has better degassing function, and is not easy to plug.This is practical new
Type uses filtration material, can effectively cross the grains of sand in drainage, it is only necessary to which upper and lower two hemispheres are fixed, and structure is simple.
Detailed description of the invention
Fig. 1 is the general assembly structural schematic diagram of the utility model embodiment water conservancy civil engineering single slope drainage exhaust valve.
Fig. 2 is the structural schematic diagram of episphere in the utility model embodiment.
Fig. 3 is the structural schematic diagram of lower semisphere in the utility model embodiment.
Fig. 4 is the structural schematic diagram of hose in the utility model embodiment.
Specific embodiment
In order to which the purpose of this utility model and advantage is more clearly understood, with reference to embodiments to the utility model into
Row is further described.It should be appreciated that specific embodiment described herein is only used to explain the utility model, and do not have to
In restriction the utility model.
As Figure 1-Figure 4, the utility model embodiment provides a kind of water conservancy civil engineering single slope drainage exhaust valve, packet
Include episphere 3,2 four part of lower semisphere 4, hose 1 and protection cap；The episphere 3 is connected with lower semisphere 4 by bolt 5,
The hose 1 is extracted out from the outlet pipe 6 on 3 top of episphere, and the top of the episphere 3 is equipped with a protection cap 2；The glue
Leather hose 1 is extracted out from protection cap 2, and one end is connected in the outlet pipe 6 on 3 top of episphere.It is uniformly distributed on the lower semisphere 4 to have
Drainage stomata, and geotextiles are filled in the episphere 3 and lower semisphere 4.The episphere 3 and lower semisphere 4 include
Hemisphere and it is mounted on the outer peripheral outer ring in hemisphere open end, offers the bolt hole matched on two outer rings.Under described
In hemisphere 4 at center be equipped with a pilot pin 7, the tail end of the pilot pin with it is affixed at the center of 4 inner bottom surface of lower semisphere, the other end prolongs
It extends in episphere 3.
When this specific implementation is arranged, include the following steps:
S1, reservoir bottom build be laid with geomembrane before, lower semisphere is first fixed on surface in bottom storehouse layer of sand, lower semisphere
One layer of geotextiles are wrapped up in outside, prevent the grains of sand from blocking inlet opening；
S2, laying geomembrane is built in reservoir bottom, and the pilot pin of lower semisphere center is made to penetrate the geotechnique
Film facilitates positioning when episphere installation；
S3, the position for finding lower semisphere installation cut corresponding geomembrane above lower semisphere；
S4, hose is hauled out on the inside of episphere, hose is blocked in episphere water outlet just；
S5, geotextiles will be filled up in episphere and lower semisphere, the bolt hole being then aligned on episphere and lower semisphere uses
Bolt fixes upper and lower hemispheres；It installs.
Lower semisphere is fixed below reservoir bottom geomembrane by this specific implementation, and the geomembrane right above lower semisphere is cut
It removes, the moisture and gas in bottom storehouse sand bed enter from the drainage port on lower semisphere spherical shell surface.Filling geotechnique in two hemispheres
Cloth is as filtration material, and using the fixed two hemispheres of bolt, hose is extracted out from the water outlet pipe part of episphere.In this way bottom storehouse moisture and
Gas enters in ball from lower half ball, and after geotextiles anti-filter in ball, with the increase of water pressure, moisture and gas are by rubber
Tube stay is opened, to flow into library.When bottom storehouse moisture is less, also less into the moisture in ball, water pressure is smaller, can not strut
Hose, so that moisture in library be effectively prevent to flow backwards.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, can also make several improvements and retouch, these improve and
Retouching also should be regarded as the protection scope of the utility model.
