TECHNICAL FIELD
The present disclosure belongs to the technical field of wa- ter supply, belongs to water supply pipeline thermal insulation and freezing prevention, and specifically relates to a water sup- ply pipeline water-break drainage anti-freezing converter and method.
BACKGROUND ART
The statements herein merely provide background art related to the present disclosure and do not necessarily constitute prior art.
Under the influence of climate and latitude, a water supply system of northern villages and towns also has the problem that pipelines are frozen and blocked due to low temperature in winter.
At present, anti-freezing measures of water supply pipelines in rural areas are simple and crude, the operation is very inconven- ient, and certain freezing risks exist. For water supply pipelines of villages and towns, main pipes are generally buried below freezing lines and are difficult to freeze; and after the pipeline enters a house, the pipeline on the ground, namely the last meter of the pipeline, is a key object for thermal insulation and freez- ing prevention. Through research, the inventor finds that no good solution is provided for the freezing problem of the overground parts of the water supply pipelines at present.
SUMMARY
Aiming at the problems existing in the prior art, the present disclosure aims to provide a water supply pipeline water-break drainage anti-freezing converter and method, which are used for solving the problem that thermal insulation and freezing preven- tion are difficult for water supply pipelines of villages and towns.
In order to achieve the above purpose, the present disclosure is realized through the following technical scheme:
In a first aspect, the present disclosure provides a water supply pipeline water-break drainage anti-freezing converter, com- prising a shell, a force bearing component and a piston assembly, wherein the shell is provided with a water inlet flow channel, a wa- ter outlet flow channel, a drainage flow channel and a piston cyl- inder, and the four channels are connected with one another; one end of the force bearing component is located outside the shell, the other end of the force bearing component is arranged in the shell, the piston assembly is arranged in the piston cylinder, and the end of the piston assembly is connected with the force bearing component; the piston assembly comprises a first piston, a second piston and a third piston, and the three pistons are all arranged on a piston rod, so that the movement path of the first piston is a piston cylinder part between the water inlet flow channel and the force bearing component; the movement path of the second piston is a piston cylinder part between the water inlet flow channel and the water outlet flow channel and between the water outlet flow channel and the drainage flow channel; and the movement path of the third piston is the piston cylinder part between the water outlet flow channel and the drainage flow channel.
In a second aspect, the present disclosure provides a water supply pipeline water-break drainage anti-freezing method, com- prising the following steps: during normal water supply, a first piston is located on the piston cylinder part between the water inlet flow channel and the force bearing component, and the part is sealed; a second piston is located between the water outlet flow channel and the drainage flow channel, so that the water outlet flow channel communicates with the water inlet flow channel, and meanwhile, the drainage flow channel is sealed; during water-break drainage, acting force is applied to the force bearing component, so that the second piston is located be- tween the water inlet flow channel and the water outlet flow chan- nel, and the water outlet flow channel is separated from the water inlet flow channel; and a third piston leaves the drainage flow channel to open the drainage flow channel.
The present disclosure in one or more embodiments has the following beneficial effects: firstly, a heat tape is not used as a thermal insulation and freezing prevention measure, so that electric charge can be saved for town users, and meanwhile, the heat tape is prevented from be- ing placed in water for a long time to cause the risk of electric leakage; secondly, when the temperature is low in winter and water is not needed, a change-over switch is placed in a drainage state, the water supply function of underground pipelines is turned off while drainage of easily-frozen pipelines on the ground is com- pleted, and the purpose of freezing prevention of the water supply pipelines is achieved; when water is needed, the change-over switch can be placed in a water supply state, the drainage func- tion is turned off at the moment, and the pipelines recover the water supply function; thirdly, when the weather is warmed up or the change-over switch is frequently used in the daytime in winter, the change- over switch only needs to be placed in the water supply state, the water supply pipeline can keep the water supply function all the time, the change-over switch does not need to be frequently start- ed, and the waste of water resources is reduced; fourthly, although certain water resources are wasted when during drainage of the equipment, the drainage amount is small each time, the drainage water is clean in quality and generally permeates into the ground, and finally underground water is sup- plemented without causing underground water pollution;
In consideration of thermal insulation and freezing preven- tion of the equipment, the equipment can be buried underground or wrapped with a thermal insulation material; and fifthly, a pedal type switch is used, hand contact is avoid- ed, and safety and sanitation are relatively achieved.

The present disclosure is further described below in combina- tion with the attached figures.
As shown in FIG. 1, the water supply pipeline water-break drainage anti-freezing converter comprises a pedal type switch, a connecting device, a piston device and a converter shell. The pis- ton cylinder 12 of the piston device is connected with the water inlet flow channel 14 and the water outlet flow channel 17, and the bottom of the piston cylinder 12 is the drainage flow channel 22; the joint of the water inlet flow channel 14 and the piston cylinder 12 is higher than that of the water outlet flow channel
17 and the piston cylinder 12 by a certain distance; the pedal type switch drives the first piston, the second piston and the third piston in the piston device to move up and down in the pis- ton cylinder 12 through the connecting device, the three pistons are matched with one another to complete conversion of water-break drainage and water supply states, and the piston device, the water inlet flow channel 14, the water outlet flow channel 17 and the drainage flow channel 22 on the piston device are completely sur- rounded and protected by the converter shell.
The lower part of the connecting device is connected with a switching pedal, and the lower part of the connecting device is connected with the piston device; a spring is installed in the connecting device, so that the pressure of the upper pedal type switch can be transmitted to the piston rod of the lower piston device to further drive the three pistons to move in the piston cylinder; the piston cylinder gasket sealing ring and a spring gasket sealing ring are installed at the joint of the connecting device and the piston device and can play a role in preventing in- flowing water from overflowing from the upper part of the piston cylinder.
The pedal type switch applies force to the spring 6 in the connecting device below through the switching pedal 1 and a switching connecting rod 2, a connecting rod slideway 3 keeps the connecting rod straight when the switch is treaded, and meanwhile the effect of reducing cold air entering is achieved.
The joint of the piston device and the water inlet flow chan- nel 14 and the joint of the piston device and the water outlet flow channel 17 are wrapped with the converter shell, and the con- verter shell can play a role in protection due to the fact that the equipment needs to be buried underground for preventing freez- ing.
When the first piston 11 is located above the water inlet flow channel 14 and the second piston 15 is located between the water inlet flow channel 14 and the water outlet flow channel 17, the water inlet flow channel 14 and the water outlet flow channel 17 are blocked by the second piston 15, so that water cannot con- tinue to enter the water outlet flow channel 17, the water outlet flow channel 17 communicates with the drainage flow channel 22, so that drainage is completed, namely water-break drainage is com- pleted; when the switching pedal 1 is treaded, the spring is stressed and compressed to drive the piston rod and all the pis- tons to move downwards, the second piston 15 moves to the position below the water outlet flow channel 17, the water inlet flow chan- nel 14 communicates with the water outlet flow channel 17, and wa- ter supply is completed; and at this time, the third piston 21 is moved to the lower piston cylinder, and the drain opening is closed.
The switching pedal 1 is used for switching the water drain- age state and the water supply state. The connecting rod slideway 3 keeps the connecting rod straight when the switch is treaded, and meanwhile the effect of reducing cold air entering is achieved. When the switch pedal 1 is treaded, the switching con- necting rod 2 acts on the switching spring fastener 4, and the switching spring fastener 4 drives the upper spring connecting disc 5, the spring 6 and the lower spring connecting disc 8 to move up and down through up-and-down movement. The lower part of the lower spring connecting disc 8 is connected with the piston rod 13, so that three pistons such as the first piston 11, the second piston 15 and the third piston 21 are driven to move up and down, and the three pistons are matched with one another to com- plete the switching of water-break drainage and water supply states.
As shown in FIG. 2, it is assumed that the positions of the switch and the piston are in an initial state at this time, and in the state, the water inlet flow channel 14 and the water outlet flow channel 17 are blocked by the second piston 15, so that water cannot continue to enter the water outlet flow channel 17; and the water outlet flow channel 17 communicates with the drainage flow channel 22, so that drainage is completed, namely water-break drainage is completed. At the moment, the first piston 11 is in close contact with the piston cylinder 12, the effect of prevent- ing inflowing water from overflowing from the upper part of the piston cylinder is achieved, meanwhile, the first piston 11 press- es the piston cylinder gasket sealing ring 9, and the double-
sealing effect of the upper part of the piston cylinder 12 is achieved.
