Abstract
The utility model discloses a supply wet return to prevent connecing wrong structure, including main -supply (1) and main wet return (2), one distributive pipe (6) are respectively connected in main -supply (1) and main wet return (2), and two distributive pipe (6) and delivery pipe (3), wet return (4) are through cross valve (5) hookup. The utility model discloses a switching of cross valve can make delivery pipe 3 and 4 exacts of wet return connect main -supply 1 and main wet return 2.
Description
Technical field
The utility model relates to a kind of pipe connecting structure of water.
Background technology
When constructing, feed pipe and return pipe often can connect instead; feed pipe is received on main water return tube; and usually can not find wrong at During Initial Stage Construction; general is all could find whether water supply and return pipe connect instead after whole construction finishing; this time is just pretty troublesome to correct, and needs the place of removing a lot of completion.
Summary of the invention
The technical problems to be solved in the utility model is: for the problem being difficult to amendment after feed pipe and return pipe wrong, provide a kind of structure that can prevent wrong.
The technical solution of the utility model is:
A kind of for the anti-wrong structure of return pipe, comprise main-supply and main water return tube, main-supply and main water return tube are respectively connected a distributive pipe, and two distributive pipes and feed pipe, return pipe are connected by four way valve.
The beneficial effects of the utility model:
Cold water water pipe is linked up by four way valve by the utility model, so no matter connect to or wrong, the conversion can being undertaken for return pipe by four way valve.
accompanying drawing illustrates:
Fig. 1 is the utility model structural representation.
Detailed description of the invention
As figure, feed pipe 3 is connected two distributive pipes, 6, two distributive pipes 6 with return pipe 4 by four way valve 5 and connects main water return tube 2 and main-supply 1 respectively.By the switching of four way valve, feed pipe 3 and the correct connection main-supply 1 of return pipe 4 and main water return tube 2 can be made.
Claims (1)
1. one kind supplies the anti-wrong structure of return pipe, comprise main-supply (1) and main water return tube (2), it is characterized in that: main-supply (1) is respectively connected a distributive pipe (6) with main water return tube (2), two distributive pipes (6) and feed pipe (3), return pipe (4) are connected by four way valve (5).
