Abstract

The utility model relates to a pipe connecting device, wherein, the both ends of a pipe body of the utility model are respectively provided with a water inlet end and a water outlet end, and a distant wall is arranged in a central position in the pipe body. The interior of the pipe body is divided into two parts by the distant wall, and through holes are arranged on side walls of the pipe body at each end to cause the utility model to achieve the effect of connecting a branch pipe in the outside and returning to connect the branch pipe. The utility model is characterized in that a through channel is arranged on the distant wall, and a valve which can cause water to flow from the water inlet end to the water outlet end is arranged on the through channel, so the utility model has the function that the water at the water inlet end can directly enter the water outlet end. A check valve which can cause the water to flow from a returning connecting pipe to the water outlet end is arranged at a through hole of the water outlet end in order to avoid water backflow.

Description

Tube coupling device

The utility model relates to a kind of tube coupling device, is meant a kind of can the turnover between the water end (W.E.) at two ends especially, forms the tube coupling device of an external pipe that separates, and makes to simplify this kind connection pipe fitting.

Please join shown in Figure 1, be to be general common tube coupling device, by shown in this figure as can be known, general common tube coupling device mainly is to be provided with a pipe joint 2 by a body 1 in one end tool, the feed-water end 3 that is linked a water source, end then is consolidated in a waterexit end 4 (can be a water tap) in addition, on body 1 one end appropriate locations, optionally can be provided with an open-work 5 in addition, when can being flowed into by feed-water end 3, the water source annotates prediction by pipeline via this above-mentioned open-work 5, deliver in other treatment facilities, carry out filtration treatment etc. such as having installed the filtrating equipment place.

But from the above mentioned as can be known, the water that general common tube coupling device all can't be produced above-mentioned external processing (filter process), again tieback is to same coupling gear discharging, therefore need connect an additional pipe joiner in addition uses, so meet the occasion of handling water in advance, then need possess the tube coupling device more than two, just can reach the effect of expection.

It is a kind of simple in structure that the purpose of this utility model is to provide, pipe multi pack easy to use is put, its mainly be by a body in its two end respectively tool be provided with feed-water end and waterexit end, and the appropriate location is provided with a partition in body, make the pipe inner region be divided into two sections, and on corresponding body two section sides, be provided with first open-work and waterexit end tool and establish second open-work respectively at the feed-water end tool, the water source can be flowed into via this feed-water end, flowing to external treatment device (as filtrating equipment) via above-mentioned first open-work again handles, to handle the water that is produced again, tieback to the second through-hole position, make by the waterexit end and flow out for utilization, making to reach in same adapter position needs two to take over just attainable adapter operation of unit originally.

For avoiding the water-outlet quantity of waterexit end, the shortcoming that reduces because of pressure, the utility model can be offered the passage that connects two sections on above-mentioned partition, and establish the reverse stop valve of feed-water end toward the circulation of waterexit end direction at this passage tool, make the water of feed-water end can directly enter the waterexit end, this is another purpose of the present utility model.

For avoiding refluxing because of the lower water that makes of hydraulic pressure of water tieback pipe end, therefore also can be equiped with the check valve of a tie back stem toward the circulation of waterexit end direction at above-mentioned second through-hole position, can solve above-mentioned puzzlement, this is a purpose more of the present utility model.

As for detailed construction of the present utility model, application principle, effect and effect, then please refer to each graphic explanation of doing, can be understood completely:

Fig. 1 is the overall perspective view of common tube coupling device;

Fig. 2 is an overall perspective view of the present utility model;

Fig. 3 is a whole cross-sectional view of the present utility model;

Fig. 4 is the utility model one preferred application example floor map;

Please join Fig. 2, shown in Figure 3, by each diagram as can be known, the utility model mainly be by body 10 in its two end respectively tool be provided with the feed-water end 102 and a waterexit end 103 at a water source, and be provided with a partition 104 between body 10 two ends, it is separated is two pipeline sections, and tool is provided with first open-work 105 and second open-work 106 on the sidewall of corresponding two pipeline sections respectively, so between first open-work 105 and second open-work 106, can external suitable water treatment apparatus, have sufficient processing before allowing water use; Again, offer the path 10 7 that always pierces between water end (W.E.) 102 and the waterexit end 103 on the above-mentioned partition 104, and on this path 10 7, be equiped with first reverse stop valve 70 of a feed-water end toward the waterexit end one-way flow; And also be equiped with one on second open-work 106 by outer second reverse stop valve 80 toward interior one-way flow.

Please join shown in Figure 4, for utilizing a reverse osmosis processing system, the utility model is example, so that characteristic of the present utility model to be described, by shown in this figure as can be known, the utility model can apply on the reverse osmosis water treatment apparatus, make body 10 feed-water ends 102 of tube coupling device connect the water source, the waterexit end is connected in a water tap 20, when making liquid flow into by the feed-water end 102 of body 10, flow out via above-mentioned first open-work, 105 places, and by an external pipeline group 30 filtrating equipment 40 places are delivered at the water source and carry out filtration treatment, utilizing film apparatus 50 to impose reverse osmosis again handles, it is standby that general's pure water after treatment is sent to water butt 60 again, for drinking or using, and the waste water that above-mentioned reverse osmosis membrane device 50 is produced when filtering, can be via pipeline group 30 tiebacks to the second above-mentioned open-work 106, flow out by the waterexit end again, so not only can control discharged waste water, the utilization again that is provided more is enough to reach the purpose at environmental protection and saving water source, and reaching for this purpose, the utility model only can be reached with single tube coupling device, the more simple and easy and saving cost of processing operation.

And the first above-mentioned reverse stop valve 70 has the function that the water source that feed-water end 102 is provided directly provides water end (W.E.) 103; 80 of second reverse stop valves are avoided descending and making the phenomenon of water adverse current because of returning hydraulic pressure in the road pipeline group 30 with this.

In sum, this kind tube coupling device of the present utility model has advantage simple in structure, easy to use really, can improve common technique is handled two tube coupling devices of occasion need of water in advance at need shortcoming.
