Abstract
The utility model relates to an anti-freezing water pipe. The anti-freezing water pipe comprises an up-down water pipe. The lower portion of the up-down water pipe is provided with a downflow water valve. An upflow water valve is arranged in parallel with the downflow water valve. An emptying air exhaust valve is arranged at the center of the up-down water pipe. Another end of the emptying air exhaust valve is connected with an air exhaust pipe. An emptying air inlet pipe is disposed at the upper bending portion of the up-down water pipe, and is inserted along the water inlet direction of the up-down water pipe. The emptying air inlet pipe is provided with am emptying air inlet valve. The emptying air inlet valve and an emptying water draining valve belong to miniature normally open valves. The utility model has the advantages of simple structure, ingenious design and convenient operation, and has emptying and anti-freezing functions of a mechanical type automatic up-down pipeline.
Description
Technical field:
The present invention relates to a kind of antifreeze water pipe.
Background technology:
The evacuation and anti-freezing in the upper and lower conduit road of present attemperater that uses and solar water heater, must close or open emptying admission valve and emptying draining valve before and after the water up and down, use pretty troublesome, in case forget and close or open emptying admission valve and emptying draining valve, will go up water, perhaps put not water outlet, occur water pipe especially easily winter and freeze stifled phenomenon, bring very big inconvenience for our life.
Summary of the invention:
The objective of the invention is provides a kind of structure ingenious, easy to use in order to overcome above deficiency, the automatic antifreeze water pipe of water up and down of mechanical type.
Purpose of the present invention is achieved through the following technical solutions a kind of antifreeze water pipe, comprise upper and lower conduit, be provided with water valve down in the upper and lower conduit bottom, be provided with water supply valve in following water valve place parallel connection, be provided with the emptied of exhaust gases valve at the upper and lower conduit middle part, the other end of emptied of exhaust gases valve is connected with stack, knee, upper end at upper and lower conduit is provided with the emptying air inlet pipe, and the emptying air inlet pipe is plugged on the water inlet direction of upper and lower conduit, be provided with the emptying admission valve on the emptying air inlet pipe, emptying admission valve and emptying draining valve are miniature normally open valve.
The present invention compared with prior art has the following advantages:
It is simple in structure, design is exquisite, easy to operate, can utilize the moving principle of learning of the effect of gravity and fluid to reach voluntarily water up and down, thereby play antifreeze effect.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Number in the figure: water valve, 3-water supply valve, 4-emptying draining valve, 5-stack, 6-emptying air inlet pipe, 7-emptying admission valve under 1-upper and lower conduit, the 2-.
The specific embodiment:
In order to deepen the understanding of the present invention, the invention will be further described below in conjunction with embodiment and accompanying drawing, and this embodiment only is used to explain the present invention, does not constitute the qualification to protection domain of the present invention.
Show a kind of antifreeze water pipe of the present invention as Fig. 1, comprise upper and lower conduit 1, be provided with water valve 2 down in upper and lower conduit 1 bottom, be provided with water supply valve 3 in following water valve 2 places parallel connection, be provided with emptying draining valve 4 at upper and lower conduit 1 middle part, the other end of emptying draining valve 4 is connected with stack 5, be provided with the emptying air inlet pipe 6 of certain altitude in the knee, upper end of upper and lower conduit 1, and emptying air inlet pipe 6 is plugged on the water inlet direction of upper and lower conduit 1, be provided with emptying admission valve 7 on emptying air inlet pipe 6, emptying admission valve 7 and emptying draining valve 4 are miniature normally open valve.
Utilize the effect of principle of hydrodynamics and gravity, during last water, emptying air inlet pipe 6 produces negative pressure, not closing under the situation of emptying admission valve can above water, because emptying draining valve 4 is normally open valves, can pass through a spot of water or gas, even do not close also water up and down of emptying draining valve 4 up and down during water.
