The invention will be further explained with reference to the drawings.
As shown in figure 1, the water supply pipeline water cut-off and drainage anti-freezing converter comprises a pedal switch, a connecting device, a piston device and a converter shell. The piston 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 water drainage flow channel 22; the joint of the water inlet channel 14 and the piston cylinder 12 is higher than the joint of the water outlet channel 17 and the piston cylinder 12 by a certain distance; the foot switch drives a first piston, a second piston and a third piston in the piston device to move up and down in the piston cylinder 12 through the connecting device, the three pistons are mutually matched to finish the conversion of the water cut-off and water drainage states, and the piston device, the water inlet flow channel 14, the water outlet flow channel 17 and the water drainage flow channel 22 on the piston device are completely surrounded and protected by the converter shell.
The upper part of the connecting device is connected with the switch pedal, and the lower part of the connecting device is connected with the piston device; the connecting device is internally provided with a spring which can transmit the pressure of the upper pedal switch to a piston rod of the lower piston device to further drive the three pistons to move together in the piston cylinder; the piston cylinder gasket sealing ring and the spring gasket sealing ring are arranged at the joint of the connecting device and the piston device, so that the function of preventing water from overflowing from the upper part of the piston cylinder can be achieved.
The foot switch applies force to a spring 6 in a lower connecting device through a switch pedal 1 and a switch connecting rod 2, and a connecting rod slideway 3 keeps the connecting rod straight when the switch is trodden and has the function of reducing cold air entering.
The joint of the piston device, the water inlet channel 14 and the water outlet channel 17 is wrapped by the shell of the converter, and the shell of the converter can play a role in protection because the equipment is buried underground for freeze prevention.
When the first piston 11 is positioned on the water inlet runner 14 and the second piston 15 is positioned between the water inlet runner 14 and the water outlet runner 17, the water inlet runner 14 and the water outlet runner 17 are blocked by the second piston 15, so that water cannot continuously enter the water outlet runner 17, and the water outlet runner 17 is communicated with the water drainage runner 22, so that water drainage is completed, namely water cut-off and water drainage is completed; the switch pedal 1 is stepped, the spring is stressed and compressed to drive the piston rod and all the pistons to move downwards, the second piston 15 moves to the position below the water outlet flow passage 17, and the water inlet flow passage 14 is communicated with the water outlet flow passage 17 to complete water supply; at this time, the third piston 21 moves to the lower cylinder, and the drain opening is closed.
The state conversion of water drainage and water supply is started by switching the pedal 1. The connecting rod slideway 3 keeps the connecting rod straight when the switch is trampled and has the function of reducing the entering of cold air. When the switch pedal 1 is stepped on, the switch connecting rod 2 acts on the switch spring buckle 4, and the switch spring buckle 4 drives the upper spring connecting disc 5, the spring 6 and the lower spring connecting disc 8 to move up and down through the up-and-down movement. The lower part of the lower spring connecting disc 8 is connected with a piston rod 13, so that three pistons such as a first piston 11, a second piston 15 and a third piston 21 are driven to move up and down, and the three pistons are matched with each other to complete the conversion of water cut-off and water discharge states and water flow states.
As shown in fig. 2, assuming that the switch and the piston are in the initial state, the water inlet channel 14 and the water outlet channel 17 are blocked by the second piston 15 in this state, so that the water flow cannot continue to enter the water outlet channel 17; the water outlet channel 17 is communicated with the water discharge channel 22, so that water discharge is completed, namely water cut-off water discharge is completed. At this time, the first piston 11 and the piston cylinder 12 are in close contact with each other to prevent the inflow water from overflowing from the upper portion of the piston cylinder, and the first piston 11 presses the piston cylinder gasket seal ring 9 to perform a double sealing function on the upper portion of the piston cylinder 12.
In this state, the switch pedal 1 is stepped, the spring 6 is stressed to compress to drive the piston rod 13 and all the pistons to move downwards, the second piston 15 moves to the position below the joint of the water outlet channel 17 and the piston cylinder 12, and the water inlet channel 14 is communicated with the water outlet channel 17 to complete water supply (shown in fig. 3). At this time, the third piston 21 moves to the drain passage 22, the drain opening 23 is closed, and the third piston 21 and the drain opening gasket 23 are pressed against each other to perform a double sealing function of the drain opening 23. In addition, the first piston 11 is still in close contact with the piston cylinder 12 to play a role in preventing the inflow water from overflowing from the upper part of the piston cylinder 12, and meanwhile, the lower spring connecting disc 8 is tightly pressed with the spring cylinder gasket sealing ring 10 to play a role in double sealing on the upper part of the piston cylinder 12.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
