Abstract
The utility model discloses a double-hole merged inner pipe plug head. The double-hole merged inner pipe plug head comprises an inner pipe and an outer pipe which are mutually connected in a rotary way, wherein the holes of the inner pipe are arranged on the pipe wall of the inner pipe, the holes of the outer pipe, which are communicated with the holes of the inner pipe, are arranged on the pipe wall of the outer pipe, and the number of the outer holes is more than 1; the back end of the inner pipe is sequentially and fixedly connected with fastening threads and a water tap; under the condition that the double-hole merged inner pipe plug head is communicated with water, the pressure of the double-hole merged inner pipe plug head can be relieved by communicating the holes of the inner pipe, the holes of the outer pipe and the holes of a rubber pipe, which is convenient to install front nuts; after installation, the outer pipe is rotated, and the holes of the inner pipe, the holes of the outer pipe and the holes of the rubber pipe are sealed; meanwhile, back nuts are twisted for fixing the outer pipe; and the utility model has simple structure and is convenient to use.
Description
Technical field
The utility model relates to a kind of pipe fitting, relates to a kind of diplopore internal thread plug of joining in particular.
Technical background
In daily life, it is frequent thing that the water pipe explosion is leaked, but is often often needing to close the water source in the process of maintenance; Especially in emergency circumstances, when needing leak stopping, can't implement leak stopping because hydraulic pressure is excessive.
Summary of the invention
Provide a kind of diplopore internal thread plug of joining for addressing the above problem the utility model, it is characterized in that: the described diplopore internal thread plug of joining comprises interior pipe and the outer tube that is rotationally connected mutually;
Wherein, the tube wall of interior pipe is provided with inner orifice, and the tube wall of outer tube is provided with the outer pore corresponding with inner orifice.
The rear portion of pipe is fixedly connected with binding thread, interior pipe back-end closure in described.
The inboard of described outer tube also is provided with the inner seal flexible pipe, and the inner seal flexible pipe is provided with the sebific duct hole corresponding with outer pore;
Outer tube and inner seal flexible pipe two ends are expansion shape hatch frame, are set with rear nut on the expansion shape hatch frame of outer tube back-end, the internal thread of rear nut and binding thread interlock;
Be set with on the outer dilator tube shape hatch frame and chase after tight nut, the outside that the chases after tight nut preceding nut that also has been threaded.
Described inner orifice is corresponding with outer pore, and the quantity in hole is more than 1 or one.
Useful technique effect of the present utility model is: diplopore is joined the internal thread plug under the condition of water flowing, by UNICOM's inner orifice, outer pore and sebific duct hole, can alleviate diplopore and join that the pressure of internal thread plug is convenient installs preceding nut, installing back rotation outer tube, fixedly outer tube of rear nut is reversed in sealing inner orifice, outer pore and sebific duct hole simultaneously; Simple in structure, easy to use.

Embodiment
The diplopore internal thread plug of joining comprises interior pipe 3 and the outer tube 10 that is rotationally connected mutually;
Wherein, the tube wall of interior pipe 3 is provided with inner orifice 2, and the tube wall of outer tube 10 is provided with the outer pore 7 with inner orifice 2 UNICOMs, and the quantity in outer hole is more than 1; In pipe 3 rear end be fixedly connected sequentially binding thread 9 and water tap 13.
Wherein, the inboard of outer tube 10 is also pasted and is provided with inner seal flexible pipe 11, and inner seal flexible pipe 11 is provided with the sebific duct hole 8 with outer pore 7 UNICOMs; Outer tube 10 and inner seal flexible pipe 11 two ends are expansion shape hatch frame, are set with rear nut 1 on the expansion shape hatch frame of outer tube 10 rear ends, the internal thread of rear nut 1 and binding thread 9 interlocks; Be set with on the outer tube 10 expansion shape hatch frames and chase after tight nut 6, nut 5 before the outside that chases after tight nut 6 also has been threaded.
In the process of using, elder generation adjusts to outer pore 10 and inner orifice 2 state of UNICOM, with 4 pairs of front ports on hose nozzle, then preceding nut 5 is received on the water pipe, adjust the state that outer pore 10 and inner orifice 2 are adjusted to the mutual dislocation sealing then, twist rear nut 1 backward and twist preceding nut 6 forward, fix outer tube 10, install.
