Abstract

The utility model discloses a sleeve-valve grouting bidirectional grout sealer comprising a base. Two radial threaded holes are arranged on the base, a pressure regulating plug, a pressure spring, a wheel seat and an edged gear are sequentially installed in the threaded holes via reverse directions, and a hollow grouting inner tube is sleeved in the base. A bearing pad, a V-shaped sealing ring, a bearing pad, a top seat, a top tube, a top seat, a bearing pad, a V-shaped sealing ring, a bearing pad, a thrust bearing, a bearing pad and a rotary threaded sleeve are sequentially mounted on the grouting inner tube tightly against the base. Grouting holes are arranged at the corresponding positions on the top tube and the grouting inner tube. An inner ring of a hollow threaded rod is sleeved on the grouting inner tube, and an outer ring is in threaded connection with the rotary threaded sleeve. A forward spinning pressing external tube is connected with the rotary threaded sleeve by a retaining joint. The grouting tube is connected with the hollow threaded rod by a quick connector and a reducing connector. The inner tube of the sleeve-valve grouting bidirectional grout sealer is changed into a flexible tube, thereby reducing the weight and enabling the connection to be convenient and reliable. The double V-shaped sealing ring can be utilized to carry out expansion sealing for bidirectional grout sealing, and the sleeve-valve grouting bidirectional grout sealer can be perfectly compatible with the sleeve valve tubes of different diameters.

Description

The two-way grout stopping device of sleeve valve formula slip casting

Technical field

The utility model relates to a kind of slurry casting machine, is the two-way grout stopping device of a kind of sleeve valve formula slip casting specifically.

Background technology

At present, the present slurry casting machine that uses on the market, general in pipe be steel pipe, total quality is big, connects inconveniently, the common tube that is connected between the outer tube connects, poor reliability, efficient is low.Existing slurry casting machine cooperates interchangeability poor with different sleeve valve pipes.

Summary of the invention

The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, and a kind of compact conformation is provided, and is reasonable in design, and the two-way grout stopping device of sleeve valve formula slip casting of perfect performance can effectively improve or remedy the deficiency of the said goods.

In order to achieve the above object, the technical solution adopted in the utility model is: comprise base, have two radial screw bore on the base, it is stifled that pressure regulation is installed respectively in it successively, stage clip, wheel seat, the sword gear, direction is opposite, the keyway in the convex shoulder of wheel seat and whorl of base hole matches, datum axle has screwed hole to an end, pipe in the socket drain casting in it, pipe is gone up and near base the pressure-bearing pad is installed successively in the slip casting, V-shaped seal ring, the pressure-bearing pad, footstock, push pipe, footstock, the pressure-bearing pad, V-shaped seal ring, the pressure-bearing pad, thrust bearing, the pressure-bearing pad, the rotation silk braid, push pipe, the pipe corresponding section has injected hole in the slip casting, hollow screw mandrel inner ring is socketed on the interior pipe of slip casting, outer ring and rotation silk braid are threaded, dextrorotation compresses outer tube and is connected with the rotation silk braid by the retaining joint, and madjack pipe is connected with hollow screw mandrel by snap joint and reducer union.

The utility model has the advantages that:

Because the utility model changes interior pipe into flexible pipe, has alleviated weight, make connection convenient reliable; Utilize double V-shaped sealing ring to carry out the swelling sealing, can two-wayly end slurry; Change the connection between the outer tube into derotation retaining joint, improved functional reliability and efficient greatly, and and the sleeve valve pipe of different-diameter can matched well.

Description of drawings

Fig. 1 is the utility model structural representation;

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

As shown in Figure 1, the utility model is the two-way grout stopping device of a kind of sleeve valve formula slip casting, comprise base 5, have two radial screw bore on the base 5, pressure regulation stifled 4 is installed respectively in it successively, stage clip 3, wheel seat 2, sword gear 1, direction is opposite, the keyway of the convex shoulder of wheel seat 2 and base 5 screwed holes matches, base 5 axial ends have screwed hole, pipe 10 in the socket drain casting in it, near base 5 pressure-bearing pad 6 is installed successively on the pipe 10 in the slip casting, V-shaped seal ring 7, pressure-bearing pad 8, footstock 9, push pipe 11, footstock 12, pressure-bearing pad 13, V-shaped seal ring 14, pressure-bearing pad 15, thrust bearing 16, pressure-bearing pad 17, rotation silk braid 19, push pipe 11, pipe 10 corresponding sections have injected hole in the slip casting, hollow screw mandrel 18 inner rings are socketed on manages on 10 in the slip casting, outer ring and rotation silk braid 19 are threaded, dextrorotation compresses outer tube 25 by retaining joint 21,24 with the rotation silk braid 19 be connected, madjack pipe 23 is connected with hollow screw mandrel 18 by snap joint 22 and reducer union 20.

Introduce its operating principle below.

On the face of land sleeve valve nylon tube of the utility model in implanting slip casting slurry hole pushed the predetermined slip casting degree of depth, because the effect of stage clip 3, sword gear 1 compresses base 5 and sleeve valve inside pipe wall, makes pipe 10 in base 5, the slip casting, hollow screw mandrel 18 relative sleeve valve pipe clamps tightly be one.

Be rotated in the forward forward flow forming outer tube 25 and drive and screw silk braid 19 and make that pipe 10 is moved to the left in its relative slip casting, promote pressure-bearing pad 17, thrust bearing 16 is moved to the left.Because the length adjusted of footstock 9,12 and push pipe 11 is good, immutable, thrust bearing 16 promotion pressure-bearing pads 15, V-shaped seal ring 14, footstock 12, push pipe 11, footstock 9, pressure-bearing pad 8, V-shaped seal ring 7 are moved to the left pressure-bearing pad 6, pressure-bearing pad 6 is close to base 5 and is produced bidirection press, compressing and force in it external diameter to expand V-shaped seal ring 7,14 squeezes, with manage table contact surface deadend in appearance, the sleeve valve formula Grouting Pipe in the slip casting, realize two way seal.The pressure slurry entered the logical slurry hole that the madjack pipe 23 that passes to the face of land manages 10 in slip casting, push pipe 11 is provided with and entered in the sleeve valve pipe this moment, strengthened with pump pressure, and the unidirectional rubber valve of slurry compressing sleeve valve pipe outer wall setting enters in the pre-mud jacking formation pore, realizes effective slip casting.

As long as counter-rotating dextrorotation compresses outer tube 25, because dextrorotation compresses the effect of the derotation retaining joint 24 that outer tube 25 joins and can only once back out screwing silk braid 19 derotations, V-shaped seal ring 7,14 two ends releases were lost efficacy, on draw or under push away the utility model to the pre-injected hole section of next section, and repeat above operating process practice segmenting slip casting.
