This utility model solves its technical problem and takes technical scheme below to realize:

A kind of stake side one-way check grouting valve, described stake side one-way check grouting valve includes three-pronged connector and part insertion Three-pronged connector is internal and the insertion tube that interfixes, is provided with the supporting pin mounting extension spring of radial direction in described insertion tube, described draws The conical plug that spring bottom mounts closure insertion tube bottom bead blocks up.

In above-mentioned stake side one-way check grouting valve, further, three fork-joins are exposed at the mouth of pipe of described insertion tube upper end Position outside head is provided with wire drawing, and described insertion tube is directly connected to by screw thread with slip casting supervisor by described wire drawing.

In above-mentioned stake side one-way check grouting valve, further, the other two ends of described three-pronged connector and reinforcement pvc Flexible pipe is connected by ferrule fitting.

In above-mentioned stake side one-way check grouting valve, further, the bead of described insertion tube and described three-pronged connector Using being welded and fixed.

Advantage of the present utility model and good effect are:

1st, this utility model is simple to operate, slip casting efficiency high, and one-way check grouting valve is disposably by under Grouting Pipe, grouting valve Enter in the hole, reach slip casting condition and can connect slip casting.

2nd, this utility model good airproof performance, one-way check grouting valve adopts conical plug to block up and forms linear sealing with the mouth of pipe, need not , there is not the point of other possible seepages in welding.

3rd, this utility model low cost, one-way check grouting valve and Grouting Pipe connect down in the hole, without external Sleeve pipe, without many places welding.

Brief description

The technical solution of the utility model is described in further detail below with reference to drawings and Examples, but It should be known that these accompanying drawings only design for task of explanation, therefore not as the restriction of this utility model scope.Additionally, Unless otherwise indicated, these accompanying drawings are meant only to conceptually to illustrate structure construction described herein, without will carry out to scale Draw.

Fig. 1 is a structural representation for side one-way check grouting valve.

In figure:

1. three-pronged connector, 2. insertion tube, 3. supporting pin, 4. extension spring, 5. conical plug block up, 6. wire drawing, 7. slip casting supervisor, 8. plus Muscle pvc flexible pipe, 9 ferrule fittings.

Specific embodiment

Firstly, it is necessary to explanation, stake side of the present utility model one-way check below will be illustrated by way of example The concrete structure of grouting valve, feature and advantage etc., but what all of description was intended merely to illustrate, and should not be understood It is that this utility model is formed with any restriction.Additionally, being described by embodiment each mentioned by this paper or implicit any list Individual technical characteristic, or shown or implicit arbitrarily single technical characteristic in the drawings, still can be in these technical characteristics Proceed combination in any between (or its equivalent) or delete, thus obtaining this practicality that may herein directly do not refer to New more other embodiments.In addition, for the sake of simplifying drawing, same or like technical characteristic is in the same figure May only be indicated at one.

It will be understood that, when it is said that when part be ' attach ' to another part, it can be directly connected to another part or There may be intermediate member.On the contrary, when it is said that by part " being directly connected to " to another part when then it represents that there is not pars intermedia Part.

Fig. 1 gives a structural representation for side one-way check grouting valve, below to illustrate this practicality with regard to Fig. 1 new Type.

As shown in figure 1, a kind of stake side one-way check grouting valve, described stake side one-way check grouting valve includes three-pronged connector 1 Insertion tube 2 that is internal with part insertion three-pronged connector 1 and interfixing, be provided with radial direction in described insertion tube 2 mounts extension spring 4 Supporting pin 3, described extension spring 4 bottom mount closure insertion tube 2 bottom bead conical plug block up 5.

This utility model is simple to operate, slip casting efficiency high, and one-way check grouting valve disposably will enter under Grouting Pipe, grouting valve In the hole, reaches slip casting condition and can connect slip casting.This utility model good airproof performance, one-way check grouting valve adopts conical plug to block up 5 Form linear sealing with the mouth of pipe, need not weld, there is not the point of other possible seepages.This utility model low cost, one-way check is noted Slurry valve connects down in the hole with Grouting Pipe, without external sleeve pipe, without many places welding.

It is pointed out that the position exposed outside three-pronged connector 1 at the described insertion tube 2 upper end mouth of pipe is provided with wire drawing 6, described Insertion tube 2 is directly connected to by screw thread with slip casting supervisor 7 by described wire drawing 6.

For further, can also consider in this utility model, the other two ends of described three-pronged connector 1 and reinforcement Pvc flexible pipe 8 is connected by ferrule fitting 9.

As an example, in this utility model, slip casting supervisor 7 is connected with three-pronged connector 1 with reinforcement pvc flexible pipe 8, carries out Slip casting, conical plug is blocked up 5 pressures by slurry, forms path, and after the completion of slip casting, if producing backflow, conical plug is blocked up 5 upwards by slurry Top, forms linear sealing, prevents backflow of slurry.

In other embodiment of the present utility model, can also be for a side one-way check grouting valve and carry out freedom and flexibility Configuration, so as to giving full play of technical advantage of the present utility model.Just this is carried out with illustrative explanation below.

For example, in certain embodiments it may be considered that described insertion tube 2 adopts welding with the bead of described three-pronged connector 1 Fixing.

In sum, this utility model can provide one kind to have simple to operate, slip casting efficiency high, good airproof performance, low cost The stake side one-way check grouting valve of advantage.

Above example has been described in detail to this utility model, but described content is only preferable reality of the present utility model Apply example it is impossible to be considered for limiting practical range of the present utility model.All equalizations made according to this utility model application range Change and improvement etc., all should still belong within patent covering scope of the present utility model.
