The time that the time-recorder timing is the time of drain pipe drainage, can avoid constructor to forget to close the water through the section of timing control rivers, leads to rivers to discharge for a long time and causes the problem that water is wasted by a large amount.
(2) If water is directly discharged from the water discharge pipe, water flow is guided into the water collecting tank, so that the water collecting tank has a water collecting function and can be used for washing hands of constructors or cleaning appliances; when the drain valve is opened, the water in the water collecting tank is drained through the drain pipe.
(3) Can directly control the solenoid valve through manual switch and open and close, avoid wasting water.
The first preferred scheme is as follows: as a further optimization of the basic scheme, the drain pipe is Z-shaped, one end of the drain pipe connected with a water source is a first end, and the other end of the drain pipe above the water collecting tank is a second end; the water collecting tank is higher than the first end of the drain pipe, the water meter is installed at the first end of the drain pipe, and the water outlet end of the drainage pipe is located above the water meter.

The water flow cutting mode in the second case is also performed by timing of a timer; the first case is different. In the first case, the water flow is discharged directly from the drain pipe, and it is common for construction personnel to wash hands or utensils, so the amount of water used is relatively small. When no water or a small amount of water exists in the water collecting tank, the steel ball is matched with the first spherical groove under the action of the first pressure spring, so that resistance is formed on the downward movement of the water collecting tank; when the water in the water collecting tank reaches a certain amount, the total weight of the water collecting tank and the water is increased and the resistance of the steel ball and the first pressure spring is overcome, so that the water collecting tank moves downwards. After the steel ball forms the cooperation with second spherical recess, the water catch bowl is spacing again, and the switch is closed in the water catch bowl extrusion this moment to make the solenoid valve close, the drain pipe stops the drainage. After the water in the water collecting tank is discharged, the first pressure spring pushes the water collecting tank to move upwards for resetting. In this scheme, the water storage capacity of water catch bowl is less relatively, and first condition water consumption is also little, consequently can further avoid the waste of water.

When the water flow is maximum, the slide bar pushes the throttle valve baffle to rotate to the position with the minimum angle; after the water in the water collecting tank is drained, the sliding rod moves upwards under the action of the second pressure spring, the throttle valve baffle rotates to the position with the largest angle, and if the electromagnetic valve is opened, the water flow in the water draining pipe reaches the maximum flow. Consequently, open the solenoid valve when opening the drain valve, along with the discharge gradually of the water in the water catch bowl, the flow of rivers in the drain pipe will increase gradually, avoids the solenoid valve to open the back, and water gushes out suddenly from the drain pipe, leads to water to splash constructor on one's body.
The preferable scheme is four: as a further optimization of the preferred scheme three, the drain valve is a semi-automatic flushing valve, water in the water collecting tank of the semi-automatic flushing valve is pressed down to be discharged through the drain pipe, and the semi-automatic flushing valve is automatically closed after a period of time; the starting switch is arranged on a pressing head of the semi-automatic flushing valve.
In the preferred scheme, the drain valve adopts a semi-automatic flushing valve, and after the semi-automatic flushing valve is pressed down, the semi-automatic flushing valve automatically resets in a short time, so that the situation that the water collection tank cannot store water due to the fact that constructors forget to close the drain valve is avoided; in addition, the starting switch is arranged on the pressing head of the semi-automatic flushing valve, so that the electromagnetic valve can be controlled to be opened when the semi-automatic flushing valve is pressed down, and compared with the third preferred scheme, the operation is simpler and more convenient.
The preferable scheme is five: as a further optimization of the fourth preferred embodiment, the upper surface of the spoiler is a conical surface, and the small end of the conical surface faces upward. When rivers are discharged from the bleeder line, rivers impact on the spoiler, and the spoiler will lead to rivers to the periphery diffusion of spoiler, and sets up the upper surface of spoiler as the conical surface, can reduce the diffusion trend of rivers to rivers can strike the surface of water gauge effectively.
