Description
Technical field
The utility model is related to a kind of slip casting check valve.
Background technology
At this stage, it is necessary to from the outside slip casting in inside of push pipe, to be lubricated to push pipe, rise in the driving of push pipe
To the effect of protection push pipe, while being laid the foundation to continue driving forward.At present, the mechanism or valve on push pipe are universal
There is problems with：
1st, sealing is poor (if situations such as running into underground water, underground water can leak out to the inside of push pipe)；
2nd, complicated, cost is high, weight weight.
Utility model content
For defect of the prior art, the utility model provides a kind of slip casting check valve, with reach it is simple in construction, into
This low, lightweight and good airproof performance purpose.
The technical scheme that the utility model is carried is：A kind of slip casting check valve, including provided with externally threaded valve body, the valve body
Side provided with the groove in the recessed valve body, the valve block being made in the groove provided with elastomeric material, the valve block it is outer
Footpath is less than the internal diameter of the groove, and bindiny mechanism is provided between the valve block and the valve body；
At least one slurry outlet connected with the groove is additionally provided with the valve body.
As an improvement, the bindiny mechanism includes at least two shrinkage pools being arranged on the valve body, the shrinkage pool
Connecting hole is provided between the groove, the connecting hole is connected with the groove and the shrinkage pool；
The valve block, which is provided with bolt hole, the bolt hole, is provided with flat head bolt, and the flat head bolt passes through the company
Connect hole and extend in the shrinkage pool, nut is threaded with the flat head bolt in the shrinkage pool.
As a further improvement, the shrinkage pool is hexagonal hole；The nut is six-sided nut.
As a further improvement, the slurry outlet is scallop hole.
As further improving, the valve body is plastics valve body.
As improvement further, irregularly-shaped hole is additionally provided with the valve body, the irregularly-shaped hole is connected with the groove.
By adopting the above-described technical solution, a kind of beneficial effect of slip casting check valve provided by the utility model is such as
Under：
Due to the valve block being made in the groove on valve body provided with elastomeric material, the external diameter of valve block is less than the interior of groove
At least one slurry outlet connected with groove is additionally provided with footpath, valve body, bindiny mechanism is provided between valve block and valve body, so that in work
In work, valve body screw thread is attached on push pipe first, afterwards toward slurries are inputted in push pipe, reached after certain pressure, slurry outlet
The slurries at place will push up open the valve block that elastomeric material is made and export outward, and then complete slip casting；After the completion of slip casting, valve block is relied on
The elasticity of itself can automatically reset, it is to avoid the material beyond push pipe enters.
In summary, using the slip casting check valve, it both can guarantee that the slurries in push pipe were outwards exported, push pipe be avoided that again
Material in addition enters, and realizes the purpose unidirectionally exported, and good airproof performance；Meanwhile, the slip casting one-way valve structures are simple, cost
It is low, lightweight.
Because bindiny mechanism includes the shrinkage pool being arranged on valve body and the connecting hole connected with groove and shrinkage pool；On valve block
Provided with flat head bolt, flat head bolt is by connecting hole and extends in shrinkage pool, is threadedly coupled on the flat head bolt in shrinkage pool
There is nut, it is simple in construction using the bindiny mechanism, it is easy to process, and good connecting effect.
Because shrinkage pool is hexagonal hole, nut is six-sided nut, so as to be carried out by the shrinkage pool of hexagonal hole to nut
Constraint, while nut rotation can be prevented, nut departs from flat head bolt during effectively prevent slip casting.
Because valve body is plastics valve body, so as to by the valve body of plastics, can not only effectively reduce cost, and can effectively drop
The weight of low valve body.
Due to being additionally provided with the irregularly-shaped hole connected with groove on valve body, so that assisting in opening valve block can be played by profiled holes
Effect；Meanwhile, material is saved, the weight of valve body is reduce further.
