Abstract

The utility model relates to a main part of a high spouting grout-filling device, which comprises a housing, a core tube, sealing material and an axletree, wherein, the core tube comprises three different sorts of channels which are a water entering channel, a slurry entering channel and an air entering channel. The ingress of the water entering channel is positioned on the central axes of the core tube; the slurry entering channel is attached to the wall of the water entering channel; the air entering channel is positioned at the side of the core tube. The exits of the three channels are off the central axes of the core tube, and positioned on the same plane. The housing is provided with corresponding ingresses. The provided airtight coating between the ektexine of the core tube and the wall of the housing comprises a polyurethane gasket and a tailor-made bead flange. The utility model, owing to adopting the optimized structure, has the advantages of reliable and enduring airtight coating, long period of usage, and flexible rotary movement.

Description

High Shower tap

One, technical field

The utility model relates to a kind of hydraulic engineering water tap, especially relates to a kind of high pressure jet grouting equipment water tap.

Two, background technique

The high pressure jet grouting technology from the seventies by external introducing China, be used widely to the nineties, the used machinery of high pressure jet grouting technology is development thereupon also, function is complete, automation, high efficiency, low cost becomes the development trend of high spraying equipment of present stage.Present widely used high spraying equipment water tap, different demands by construction process are divided into two pipes and three pipe water taps, raising along with high spraying equipment automaticity, requirement to water tap is more and more higher, conditions such as the rationality of structure for water tap, sealing, working life, shortcomings such as the efficient and the life-span that all are related to high spraying equipment, existing water tap exists sealing relatively poor mostly, and working life is short.

Three, summary of the invention:

The purpose of this utility model provides the high Shower tap of a kind of rational in infrastructure, good airproof performance, long service life.

The technological scheme that the utility model is taked is, it is by shell, the core pipe that opposite shell is rotated, sealing material between shell and the core pipe and bearing are formed, the core pipe of high Shower tap is by three kinds of different intake tunnels, slurry intake channel, gas-entered passageway is formed, intake tunnel grows slurry intake channel, slurry intake channel grows gas-entered passageway, the import of intake tunnel is on the central axis of core pipe substantially, the slurry intake channel bag is attached to around the intake tunnel perisporium, gas-entered passageway is in a side of core pipe, intake tunnel, slurry intake channel, the outlet of gas-entered passageway departs from core tube hub axis, the place at grade, leave intake tunnel on the shell with the core pipe, the import that slurry intake channel and gas-entered passageway communicate, the sealing material between core tube wall and the outer casing inner wall adopts combination rubber seal and back-up ring.

The beneficial effects of the utility model are, owing to adopted the structure of optimizing, and rational combination seal, thus have characteristics such as lasting reliable, the long service life of sealing, rotation be flexible.

Fig. 2 is the right elevation of the high Shower tap inner core of the utility model shown in Figure 1 pipe;

Fig. 3 is the A-A sectional view of the high Shower tap inner core of the utility model shown in Figure 2 pipe;

Fig. 4 is the B-B face sectional view of the high Shower tap core of the utility model shown in Figure 3 pipe;

Fig. 5 is the C-C face sectional view of the high Shower tap core of the utility model shown in Figure 3 pipe.

Five, embodiment:

From the structural representation of the high Shower tap of the utility model shown in Figure 1 as can be seen, core pipe 8, sealing material and bearing that it is rotated by shell, opposite shell are formed, shell is connected to form by locknut 1, top cover 13, first joint 2, shell first segment 3, shell second joint 6, shell the 3rd joint 7, shell first segment 3 adopts bolt 4 to be connected with shell second joint 6, shell second joint 6 and between shell the 3rd saves 7, shell first segment 3 also is connected with suspension ring assembly 10 with shell second joint 6, and 5 end face seals of O type circle are adopted in the joint.Rotation between shell and the core pipe is realized by tapered roller bearing 12.

From Fig. 2, Fig. 3, Fig. 4, the inner core pipe figure of the high Shower tap of the utility model shown in Figure 5 as can be seen, core pipe 8 is by three kinds of different intake tunnels 14, slurry intake channel 15, gas-entered passageway 16 is formed, intake tunnel 14 grows slurry intake channel 15, slurry intake channel 15 grows gas-entered passageway 16, the inlet of intake tunnel 14 is on the central axis of core pipe 8, outlet departs from the central axis of core pipe 8, slurry intake channel 15 bags are attached to around intake tunnel 14 perisporiums, just intake tunnel 14 passes in the middle of slurry intake channel 15, the inlet of the import of slurry intake channel 15 and intake tunnel 14 is on different planes, gas-entered passageway 16 is in a side of core pipe 8, intake tunnel 14, slurry intake channel 15, the outlet of gas-entered passageway 16 all departs from the central axis of core pipe 8, the place at grade.Leave the import that communicates with intake tunnel 14, slurry intake channel 15 and the gas-entered passageway 16 of core pipe on the shell, intake tunnel 14 communicates with the water intake of top cover 13, the import of slurry intake channel 15 communicates with the stock inlet of shell first segment 3, and the import of gas-entered passageway 16 communicates with the suction port of shell second joint 6.Because between shell and the core pipe 8 is in relative rotation, so, leave certain clearance between inlet, core tube wall and the outer casing inner wall of the import of slurry intake channel 15 and gas-entered passageway 16, so that the import on the core pipe 8 communicates with import on the shell.The combination seal that sealing material between core pipe 8 outer walls and the outer casing inner wall adopts urethane seal circle 11 and special back-up ring 9 to constitute with order according to a certain direction, thereby the sealing effect of realizing ideal, the main position of combination seal is, between first joint 2 and the core pipe, between shell first segment 3 and the core pipe, shell second save 6 and the core pipe between.

By above structural design, new by this practicality with water, slurry, the gas of high pressure Behind the type, realize coaxial injection, have sealing lastingly reliably, rotate the characteristics such as flexible, be The ideal equipment of churning, fixed spray, pendulum spray.
