Abstract
The utility model relates to a frost-proof device for a running water tap, which is particularly designed for timing or non-timing water feeding of a running water pipe network without a tower in extensive countryside and in middle and small size towns. The device is a hollow cavity body, and the lower part of the hollow cavity is provided with a through hole connected with a water inlet pipe of the running water tap. A float valve is arranged in the hollow cavity, and a valve port is arranged on the top of the hollow cavity and is placed above the float-valve, and a venting hole and a whistle mouthpiece are arranged in the valve port. The device can cause air to enter the running water tap to balance air pressure when the running water pipe network stops feeding water, the device avoids forming negative pressure and storing water in the tap to freeze the tap, and the device can also whistle to prompt users when water is fed again.
Description
The utility model relates to the tap water pipeline equipment, specifically is the water tap anti-icer.
In northern China vast rural area and middle samll cities and towns, tap water has now become basically universal.But be limited to condition, have a considerable amount of tap water supply nets also to adopt no tower timing or not timing to be interrupted and supply water.Especially some rural areas, the several hrs that only supplies water by day every day no longer supplies water At All Other Times.In order to guarantee water, the user just needs to be equipped with tank in addition, so that running water pipe water storage when coming water.Because the village tap water tap generally is located at the open air, the antifreeze problem in winter just seems very important.
The purpose of this utility model is exactly that a kind of suitable interruption water tap anti-icer in the network of rivers from the beginning that supplies water will be provided.
For finishing the water tap anti-icer that the invention task designs is cavity body, and its cavity bottom has through hole to communicate with the water tap intake pipe, and float valve is arranged in the cavity, and the cavity top has valve port to place on the ball float, and vent is arranged in the valve port.
This anti-icer can have a style of one's own and be installed on the intake pipe of water tap, and can also make one with water tap becomes anti-freezing water tap.Its antifreeze principle is; When the tap water pipe network suspends water supply, the float valve that stops up valve port along with roof pressure in the reduction anti-icer cavity of hydraulic pressure descends, air can enter the running water pipe equilibrium air pressure by the vent in valve port, avoid forming the negative pressure water in running water pipe and the water tap, so just can not freeze to death water tap.And when the tap water pipe network supplied water again, the float valve come-up in the anti-icer was stopped up valve port, is sealed vent, and water tap just can not leak, and influence is used.
For the user of timely announcement when the tap water pipe network supplies water again, the vent in the valve port of the utility model anti-icer can be designed to steam whistle whistle mouth.When supplying water again, the air in the running water pipe is pushed by water, can blow steam whistle via valve cavity and vent like this, reminds the user.
Below in conjunction with accompanying drawing the utility model is described.
Fig. 1 is the utility model water tap anti-icer user mode schematic representation.
As shown in Figure 1, the water tap anti-icer is a cavity body, and its cavity 8 bottoms have through hole 9 to communicate with water tap intake pipe 10, and float valve 7 is arranged in the cavity 8, and cavity 8 tops have valve port 6 to place on the float valve 7, and steam whistle whistle mouth 5 and vent 4 are arranged in the valve port 6.The valve rod 3 of rotation water tap can make valve block 2 stop up or open valve port 1.
Claims (2)
1, water tap anti-icer is characterized in that anti-icer is a cavity body, and its cavity bottom has through hole to communicate with the water tap intake pipe, and float valve is arranged in the cavity, and the cavity top has valve port to place on the float valve, and vent is arranged in the valve port.
2, water tap anti-icer according to claim 1 is characterized in that steam whistle whistle mouth is arranged in the said valve port.
