Abstract
The present invention is " circulatory antifreezing valve ", is applicable to that China northern territory tap water supply uses, and takes valve body to move to below the frost zone, adds exhaust, circulating device measure again, reaches frost zone with the purpose of water not in the upper hose.Realized that valve and water pipe never freeze, and have played antifreeze effect.Be applicable to that not only resident living water uses, and also can be used for industry, the conveying that national defence and all fearnesses are frozen liquid.
Description
The home-use running water valve of China uses common stop valve mostly at present.Some open-air valves that use just can not normally use whenever winter, were not only water pipe and valve and froze and can not supply water, and water pipe from freezing crack, valve damage phenomenon and also happen occasionally.Not only making troubles to people's lives, also is a very big waste.Only annual just considerable to the water system used energy of heating.
For improving China northern territory watering condition in winter, energy conservation cuts the waste, and has invented " circulatory antifreezing valve ".
The present invention has mainly taked: one, open and close valve 9 and move to below the frost zone, guarantee that valve body does not freeze; Two, add exhaust plant 14, the water in the water-supply-pipe behind the valve-off 8 is discharged; Three, add circulating device 11, make that the unclean water of row all enters circulating device 11 in the water-supply-pipe 8.After making valve closing, become no hydrospace in the valve 9 above water-supply-pipes 8, reach the purpose of never freezing with this.
Its operating principle is:
When Open valve, left-handed handwheel 1, make keying screw 2 compression close springs 3 of left hand thread, start and stop lever 5, keying body 6 are moved down, pass through to open and close eight semicircle tanks of body 6 from the water of water inlet, enter water-supply-pipe 8 through the gap that opens and closes between body 6 and the sealing mat 7, flow out (also having filled with water by circulation pipe 10 in the circulating device 11 simultaneously) through delivery port.When valve-off, only need dextrorotation handwheel 1, open and close on the screw and move, start and stop lever 5, keying body 6 upwards move under the effect of closing spring 3, make the gap that opens and closes between body 6 and the sealing mat 7 be reduced to zero or negative value, just reached the purpose (pressure of its closing spring 3 is by regulating silk 4 is regulated, be adjusted to open and close body 6 and sealing mat 7 can degree of being sealed into) of valve-off.When doing antifreeze processing as need, step at the P point, make exhaust plant 14 work, the compressed air in the exhaust plant 14 enters circulating device through one way valve 13, behind the water pressurized in the circulating device 11, enters water-supply-pipe 8 through circulation pipe 10, discharges through delivery port.The unclean surplus water of row in the water-supply-pipe 8, and circulating device 11 between under the effect of difference in height, generation is to the pressure of circulating device 11, behind the gas pressurized in the circulating device, just the air leakage hole 12 from its top slowly overflows from the top of water-supply-pipe 8, make that remaining water all enters circulating device 11 in the water-supply-pipe 8, finally reach all non-icing purpose of valve body 9 and above water-supply-pipe 8.
Open and close body 6 and valve body 9 and be high pressure PEF goods, it closes spring 3 and works in anhydrous closed chamber, and other perishable position part all adopts injection-molded item and plastic spraying, to guarantee its application life.Open and close the elastic force and making a concerted effort of from the hydraulic pressure of water inlet forming of the pressure of 6 pairs of sealing mats 7 of body by closing spring 3, this makes a concerted effort can be considered steady state value, this has just guaranteed not damage because of pressure is excessive sealing mat 7, thereby has guaranteed that valve is water-tight, the non-icing function of water pipe.
When reality was used, this valve not only can use in ice period, can use in non-ice period in the same old way.Exhaust plant, circulating device were not worked, thereby can be replaced common valve to use non-ice period.Also can use instead and be button, it is become by opening the formula valve opening and closing screw.Also can be according to the demand of different water yields and the frost zone of different-thickness, the product of design different size.
It installs relation as Fig. 1, Fig. 2, and the top of circulating device 11 will be lower than frost zone and be lower than the outlet of circulation pipe 10, and air leakage hole also should be located at below the frost zone in the position of water-supply-pipe 8.
Claims (7)
1, circulatory antifreezing valve, this valve can realize that the outdoor application in winter is icing, and its principal character is as follows:
A, the valve body 9 of described valve is moved to underground, by the start and stop lever in the water-supply-pipe 85 at the top operated by handwheel,
B, described valve body one side have a circulating device 11 and water-supply-pipe 8 to connect,
C, described circulating device 11 tops and its connection an exhaust plant 14 arranged.
2, according to claim (1), there are eight semicircle tanks to communicate on the keying body 6 of keying valve with the water source.
3, according to claim (1), there is a closing spring 3 on the start and stop lever top, it is characterized in that guaranteeing to open and close the pressure of 6 pairs of sealing mats 7 of body.
4, according to claim (1), the screw thread of the keying bolt that matches with handwheel is left-handed.
5, the feature according to the described circulating device of claim (1) is:
There is an air leakage hole on a, described device top and connects with the air leakage hole 12 on the water-supply-pipe 8,
The volume of b, described device is greater than the net volume of water-supply-pipe 8.
6, the feature according to the described exhaust plant of claim (1) is:
There are an one way valve 13 and circulating device to connect below a, the described device,
The delivery space of b, described device is greater than 2 times circulating device volume.
7, according to claim (1), (2), (5), the circulation port that valve body 9, circulating device 11, water-supply-pipe communicate with circulating device all is located at underground, and its degree of depth is decided with different regions frost zone thickness, to guarantee not endure cold degree of being.
