Abstract
The present invention is a kind of new tap water anti-freezing device
This device can be turned the water of the part (on the ground and underground) that freezes of running water pipe automatically, thoroughly stops running water pipe freezed in winter clogging.Advantage of the present invention:
(1) antifreeze reliable, be applicable to any in the world severe cold area.
(2) using water wisely, the protection environment.
(3) install simply, easy to operate.
(4) cost is low, is suitable for to popularize and uses.
Description
The invention belongs to the parts in the tap water supply system.
Often freezing in cold district water supply pipe winter is a problem widely.Since what years, once proposed some schemes in the world and managed to address this problem.But going back the complete enforceable scheme of neither one is at present adopted by people.Wherein utility model patent gazette entry " a kind of antifreeze water-supply valve " second volume, No. 25.Application number 85204151, and at present state-of-the-art a kind of " tap water anti-freezing valve " by the red child's invention of 11 years old the Li Xiu in Tianjin, this valve has water flowing, cuts off the water supply and three functions of backwater, cold district or cold season after water is closed the water source, the ponding in the pipeline on the ground can be got rid of simultaneously, antifreeze effect can be played effectively.But it also has shortcoming, though have the backwater function as valve, it gets back to valve ground on every side to water, has so not only wasted water but also contaminated environment.This antifreezing valve shortcoming such as forms by plural water tap, and these shortcomings all are to hinder applying of this invention, and other defroster mechanism is more complicated, or need are not susceptible to user acceptance by other energy form.
The resident of the northern area of China and world's wide geographic area and outdoor work engineering unit often because of winter water supply pipe freeze and influence daily life and construction, the user has to round the clock that flowing water prevents that pipeline is icing, causes surprising waste thus.Shortcoming and defect for the antifreezing faucet that overcomes above-mentioned several forms, and the phenomenon of the water of putting and ending to waste, task of the present invention is that manufacturing is a kind of simple in structure, easy to use, saves steel (only needing a valving) automatically emptying device for preventing running water from freezing free from environmental pollution.
Main points of the present invention are that said automatically emptying device for preventing running water from freezing is by metal firm banking (12), valve stamen (10), and the cistern that bellows is made (9), the valve rod (5) that connection thick stick leading screw is made, valve head (7), spring parts such as (15) are formed.As figure, it can be to be made by rubber that these parts remove bellows cistern (9), also can be that rubber-like plastics, phosphor-copper, stainless steel are made, and all the other all available cast iron materials are made, its cost is lower, and each parts can the bursting by freezing distortion under severe cold.
In said metal firm banking (12), imbed inlet channel (13) and outlet conduit (1), and outlet conduit (1) is a return pipe.A groove (16) digs in the bottom centre of firm banking (12), and the end of (16) is equipped with a spring (15) at the bottom of groove, and spring (15) contacts with valve stamen (10).Be with a rubber washer (14) on the valve stamen (10), groove (16) top communicates with outlet pipe (1) and water inlet pipe (13), and valve stamen (10) is installed in can the easy on and off activity in the outlet pipe (1).Firm banking (12) upper end cover is with bellows cistern (9), and bellows cistern (9) other end is enclosed within on the valve head (7), and two ends are fixing with tightening up steel folder (11) respectively.Valve head (7) connects by feed screw nut (3) with the valve rod (5) that the link rod leading screw is made, and goes up upper end peace one turning handle (2) at valve rod (5).
According to the latitude of location, the nothing that can be placed in the underground certain depth is frozen the district when using this device, promptly with the same degree of depth of cities and towns underground water pipe.Lay the whole link rod leading screw of underground depth-adjustment according to this device and make the length of valve rod (5), be embedded in underground more deeply can be a little the length of valve rod (5).For the ease of operation, in a word valve rod (5) is basseted.
During turning handle when water (2), the valve rod that the link rod leading screw is made (5), valve head (7) make corrugated hose cistern (9) compression, valve rod after being compressed to a certain degree (7) contacts with valve stamen (10), and compression spring (15), at this moment water inlet pipe (13) is communicated with outlet pipe (1), tap water can the unobstructed flow mistake, and water rises to ground can water.
When water finishes, backward rotation handle (2), valve head (7) rise and also break away from valve stamen (10), and spring (15) reaches relaxation state, at this moment also just cut off the passage of water inlet (13) and delivery port (1), and water supply stops.When continuing backward rotation handle (2), valve head (7) drives bellows cistern (9) increases its volume, and the water in the pipeline (1) is emptied in the bellows cistern (9) so, and anhydrous having frozen in the outlet pipe (1).
Summer, water can make bellows cistern (9) keep compressive state, and valve head (7) often contacts with valve stamen (10).Open and close valve event distance is reduced to minimum, need not the water in the turned letter (1).
Advantage of the present invention:
The a antifreezing measures are reliable, are suitable for any in the world severe cold area and use.
B is easy and simple to handle to be as good as with common hydrant.The old and the young all are easy to use, and need not to climb up to climb down, and need not to discharge water to drag water.
The c using water wisely guarantees the clean environment drying.
D is simple in structure, and cost is low, and is easy to utilize.
This device is applicable to that there is the resident of freezing regional villages and small towns, street, garden in the China and the world, and the engineering unit tap water supply system of outdoor work.
Embodiment one
Steel handle (2) is Φ 6, and long 12 valve rods made from steel link rod leading screw (5) (M16, long 600) fix, the valve rod (5) by this link rod leading screw of nut (6) but rise and fall.Valve head (7) is steel pressing plate Φ 120.Its relative link rod leading screw is free to rotate, and moving thereupon when link rod leading screw (5) rise and fall.With commercially available Φ 120 rubber bellows cisterns (9) and valve head (7) and steel firm banking (12) diameter is that Φ 121 connects with the commercially available steel folder (11) that tightens up and tightens up and seal.Rubber washer (14) with Φ 15 is enclosed within on the valve stamen (10) of length 16, and its function is the tap water of opening reliably, break.Commercially available Φ 10 springs (15) are put into groove (16), and groove is Φ 16, and dark 12 also fix it with sealed screw (8).Water inlet pipe (13) is Φ 20～40 with outlet pipe (1) bore.
