Two water inlet pipe end predetermined positions are simultaneously fastened with a bolt or latch equipped with the control water to adjust inflow, are separately upwardly extending system in hydrant body central
Equipped with one for assembling the valve chamber of water control valve, the water control valve by a valve body, valve body two sides rubber pad, be filled at the work of valve inner
Plug assembly, the valve rod to operate piston component, cap, valve body top cover and interlocking operating valve lever knob formed, wherein
The piston component is formed by piston rod and the covered group of piston cylinder, and the outer diameter of the piston cylinder is waney abnormally-structured, and
Its predetermined position has been set up into and out of water hole, with the controlling changing relativeness of the piston rod inside cooperation, to reach confession, sealing
And water mixing proportion adjusts function；
The piston cylinder is that type is made by the plastic cylinder institute group of stainless steel base tube and external inclusion, which is
It is directly cut by stainless steel tube, and set up in predetermined position into and out of water hole, and the plastic cylinder is then this is stainless
Base steel pipe according to mold cavity plans emitted molding after being placed in prefabricated mold so that the plastic cylinder be integrated inclusion in
Outside the stainless steel base tube, and the corresponding hole slot of water-in and water-out hole forming in plastic cylinder relative to the stainless steel base tube, with
Group constitutes the piston cylinder of composite.
Beneficial effects of the present invention: the piston assembly structure improvement of the obtained hydrant of the present invention, primarily directed to giving
The piston cylinder of the water control valve internal piston component of water bolt carries out improvement design, through the composite structure of its piston cylinder, via general
Piston cylinder adopts the innovative design that stainless steel tube projects inclusion plastic cylinder, in the principle for not influencing its entirety and assembling relationship and function
Under, be not only able to effectively simplify its procedure for processing, more can economization material cost, while can effectively improve piston component and rubber pad
Between water-tight relationship, assign its splendid industry using upper economic benefit and practical value, thoroughly solve existing structure not to the greatest extent
Ideal perfect missing.
