Abstract

The utility model discloses a sealing needle mainly cooperates high -pressure slip casting machine to use, including slip casting pipe, metallic gasket, expandable casing, stifled ball, spring and bolt, slip casting intraduct cavity, block up for the round platform form in hollow upper end, and the cooperation rubber's that blocks up stifled ball can be of the younger generation to excellent airtight effect in slip casting, and the six angled pipe body is designed into to slip casting pipe upper end, snatching in being favorable to using, and expandable casing that slip casting pipe lower extreme utilized the bolt fastening cover to establish, the pad has the metallic gasket between the expandable casing, and the nut up end of bolt designs into the rank cusp, can prevent to skid. The utility model discloses cooperating high -pressure slip casting machine to use, having more extensive application in fields such as water conservancy water and electricity, tunnel, municipal administration, industry and civil buildings, have better seal, mesh production cost is low.

Description

A kind of Water slop injector

Technical field

This utility model is related to a kind of auxiliary work-piece of the building water-proof leak stopping that cooperation high-pressure grouting machine uses, specifically A kind of Water slop injector.

Background technology

In water conservancy and hydropower, tunnel, municipal administration, industry and the fields such as civil buildings, the situation of body of wall slight crack often occurs, continues Go down and the waterproof of building will be impacted, more serious consequence of going down for a long time to cause to cave in etc..

Water slop injector, the workpiece that a kind of cooperation high-pressure grouting machine uses, is using high-pressure grouting principle, to body of wall injectionization Learn slurry thus reaching reparation body of wall, the necessary device of water-proof repairing.Water slop injector in the market, cost is high, and Irony spheroid commonly used by stifled ball, and waterproof effect is poor.

Utility model content

The purpose of this utility model is to provide the Water slop injector of a kind of low cost, good water-proof effect, to solve the above-mentioned back of the body The problem proposing in scape technology.

For achieving the above object, this utility model provides following technical scheme：

A kind of Water slop injector, including Grouting Pipe, metallic gasket, expansion sleeve, stifled ball, spring and bolt, described Grouting Pipe For hollow tube, inside described Grouting Pipe, hypomere is provided with female thread, and described Grouting Pipe top is hexagonal body, described six angle pipes Body upper end is ballhead, leaves grouting port, the inner tube top of described Grouting Pipe is provided with round table-like blocking up in the middle part of described ballhead, The built-in stifled ball of described Grouting Pipe, described stifled ball lower end is spring, and the rotation of described Grouting Pipe lower end is fixed with bolt, on described bolt Hold as external screw thread, described stud base is nut, is arranged with expansion sleeve, described expansion sleeve between described bolt and Grouting Pipe Between be arranged with metallic gasket and expansion sleeve and be also arranged with metallic gasket with Grouting Pipe contact position.

As further program of the utility model：The material of described Grouting Pipe is metallic iron.

As further program of the utility model：Described nut upper surface is provided with rank tooth.

As this utility model further scheme：The material of described expansion sleeve and stifled ball is rubber.

As this utility model further scheme：It is hollow tubular inside described bolt.

Compared with prior art, the beneficial effects of the utility model are：This installation cost is low, and Grouting Pipe adopts metallic iron to make For body, save cost；Water resistance is good, is provided with spring in Grouting Pipe body, can not stop serosity in environment under high pressure Current, simultaneously because stifled ball is made using rubber, can be good at fitting with round table-like blocking up, contact closely, reaches excellent Sealing；Good stability, the nut of bolt is provided with rank tooth, can prevent from skidding.

Brief description

Fig. 1 is configuration schematic diagram of the present utility model.

Fig. 2 is axonometric chart of the present utility model.

Fig. 3 is the profile of Grouting Pipe of the present utility model and bolt.

Wherein：1- Grouting Pipe；1a- hexagonal body；1b- ballhead；1c- grouting port；1d- female thread；2- metallic gasket；3- Expansion sleeve；4- blocks up ball；5- spring；6- bolt；6a- external screw thread；6b- nut；6c- rank tooth；7- blocks up.

Specific embodiment

With reference to specific embodiment, the technical scheme of this patent is described in more detail.

Refer to Fig. 1-3, this device needs to coordinate high-pressure grout injector to be operated；General punching at crack, then fill in Enter this device, the grouting port 1c of this device connects high-pressure grout injector, high-pressure slip-casting, the then effect as check valve of stifled ball, prevents Injection slurry spills.

Embodiment：

A kind of Water slop injector, including Grouting Pipe 1, metallic gasket 2, expansion sleeve 3, stifled ball 4, spring 5 and bolt 6, described Grouting Pipe 1 is hollow tube, and described Grouting Pipe 1 inside hypomere is provided with female thread 1d, and described Grouting Pipe 1 top is hexagonal body 1a, hexagonal body 1a are slightly elevated above the lower tube body of Grouting Pipe 1, the convenient crawl with high-pressure grout injector, described hexagonal body 1a Upper end is ballhead 1b, leaves grouting port 1c in the middle part of described ballhead 1b, and the inner tube top of described Grouting Pipe 1 is provided with round table-like Block up 7, the built-in stifled ball 4 of described Grouting Pipe 1, described stifled ball 4 lower end is spring 5, and the rotation of described Grouting Pipe 1 lower end is fixed with bolt 6, described bolt 6 upper end is external screw thread 6a, and described bolt 6 bottom is nut 6b, is arranged between described bolt 6 and Grouting Pipe 1 Expansion sleeve 3, is arranged with metallic gasket 2 between described expansion sleeve 3 and expansion sleeve 3 is also sheathed with Grouting Pipe 1 contact position There is metallic gasket 2；Round table-like block up 7 be conducive to airtight with fitting of stifled ball 4, the then uniform expansion sleeve 3 of metallic gasket 2 Pressure.

The material of described Grouting Pipe 1 is metallic iron, and the aluminum that irony compares on market has more preferable intensity, and cost Lower.

Described nut 6b upper surface is provided with rank tooth 6c, and the setting of rank tooth 6c then ensure that expansion sleeve 3 will not be slided easily Dynamic, improve the stability of device.
