Detailed Description
The following detailed description of the embodiments of the present invention will be provided in conjunction with the accompanying drawings to facilitate further understanding of the present invention by those skilled in the art, and should not be construed as limiting the scope of the present invention.
Example 1: referring to fig. 1 and 2, the solar anti-freezing automatic water control system comprises a water tank 1, an upper water supply pipe and a lower water supply pipe 2, a hot water pipe 3 and a cold water pipe 4, wherein the top ends of the upper water supply pipe and the lower water supply pipe are transversely arranged at the bottom of an inner cavity of the water tank, the bottom ends of the upper water supply pipe and the lower water supply pipe are connected with the hot water pipe and the cold water pipe through a tee joint, and the solar anti-freezing water control system further comprises an exhaust pipe 5 and;
the exhaust pipe is sleeved outside the upper and lower water pipes and penetrates through the tee joint, the top end of the exhaust pipe is arranged at the top of the inner cavity of the water tank, a connecting port is arranged on the pipe wall of the exhaust pipe, and the upper and lower water pipes are arranged at the connecting port through a sealing ring 10 and are communicated with the inner cavity of the water tank;
the water control valve comprises a cylindrical valve body 61 with the top and the bottom sealed and the side edges provided with a water inlet and a water outlet, and the water inlet and the water outlet of the cylindrical valve body are connected with a cold water pipe; a bent pipe 62, a valve device and a first compression spring 63 are arranged in the cylindrical valve body; the bent pipe is of an L-shaped structure, a water outlet of the horizontal part of the bent pipe is connected with a water outlet of the cylindrical valve body, and a water inlet of the vertical part of the bent pipe is arranged upwards; the valve device comprises a valve 64 and a valve pull rod 65 fixed on the valve, the valve is arranged above the vertical part of the elbow, the orthographic projection of the valve completely covers the water inlet of the vertical part of the elbow, and the valve pull rod downwards penetrates through the vertical part of the elbow and the bottom of the cylindrical valve body and extends out of the cylindrical valve body; the first compression spring is sleeved at the upper part of the valve pull rod, and two ends of the first compression spring are respectively limited by the valve and the horizontal part of the bent pipe;
a water containing bucket 7 is arranged below the water control valve and is fixedly connected with the bottom of the valve pull rod; a water receiving device is arranged between the bottom end of the exhaust pipe and the water containing barrel.
The working process of the solar anti-freezing automatic water control system is as follows:
before water is supplied, no water exists in the water containing barrel, the valve is supported above the vertical part of the bent pipe by the first compression spring, and the water control valve is in an open state at the moment.
When water is supplied, the water supply valve of the cold water pipe is opened, and cold water enters the cylindrical valve body from the cold water pipe through the water inlet of the cylindrical valve body. Because the cylindrical valve body is of a sealing structure, cold water can only enter the bent pipe from the water inlet of the vertical part of the bent pipe and then flows into the cold water pipe from the water outlet of the horizontal part of the bent pipe (namely the water outlet of the cylindrical valve body). The cold water in the cold water pipe enters the water tank through the upper water pipe and the lower water pipe.
When the liquid level in the water tank is higher than the top end of the exhaust pipe, the cold water overflows into the exhaust pipe and flows into the water containing barrel through the water receiving device. Under the action of the gravity of the overflow water in the water containing barrel, the valve pull rod drives the valve to move downwards and compress the first compression spring. When the valve moves to contact with the water inlet of the vertical part of the bent pipe, the water inlet of the vertical part of the bent pipe is completely sealed, and the water control valve is in a closed state at the moment, so that automatic water control is realized. Even if the user forgets to close the water feeding valve of the cold water pipe, the cold water in the water tank cannot overflow. When the user finds that the water tank is full, the water supply valve of the cold water pipe is closed and the water in the water containing barrel is discharged, and the valve is reset under the pushing force of the first compression spring. At this time, the water control valve is restored to the open state.
The heat collecting pipe of the solar energy absorbs the heat irradiated by the sunlight to heat the water in the water tank, thereby generating hot air. Because the water tank is of a sealed structure, hot air can only enter the exhaust pipe to heat the upper and lower water pipes in the exhaust pipe, so that water in the upper and lower water pipes is prevented from freezing or the frozen ice is prevented from melting. When hot water is needed, the water outlet valve of the hot water pipe is opened, and the hot water in the water tank enters the hot water pipe through the water inlet pipe and the water outlet pipe for users to use.
Example 2: referring to fig. 1 and 3, in the solar anti-freezing automatic water control system according to embodiment 1, an air outlet 8 is formed at the top end of the water tank, and an air pressure regulating safety valve 9 is installed on the air outlet; the air pressure adjusting safety valve comprises a tubular valve body 91 with external threads on the top and the bottom, the bottom of the tubular valve body is screwed on an exhaust port, the top of the tubular valve body is screwed with a pressure regulating nut 92, a limiting plate 93 is fixed at an opening at one end of the pressure regulating nut, and a hot air outlet 94 is arranged in the middle of the limiting plate; a ball valve seat 95, a ball valve 96 and a second compression spring 97 are arranged in the tubular valve body; the ball valve seat is fixed at the inner bottom of the tubular valve body, a gas channel 98 is arranged in the ball valve seat, a concave surface matched with the ball valve is arranged at the top end of the ball valve seat, and two ends of the second compression spring are limited by the limiting plate and the ball valve respectively.
The water in the water tank is heated to generate hot air, so that the air pressure in the water tank is increased. When the air pressure in the water tank is at a normal level, the pressure of the hot air to the ball valve is small, and the ball valve is tightly attached to the concave surface at the top end of the ball valve seat under the thrust of the second compression spring. The ball valve seals the air passage in the ball valve seat, and the air pressure regulating safety valve is in a closed state at the moment.
When the air pressure in the water tank exceeds the air pressure threshold, the ball valve moves away from the ball valve seat under the pressure of hot air and compresses the second compression spring. The gas passage in the ball valve seat is opened, and the air pressure regulating safety valve is in an open state. The hot gas passes through the exhaust port, the gas passage and the inner cavity of the tubular valve body in sequence and is discharged from the hot gas outlet, so that the air pressure in the water tank is reduced. When the air pressure in the water tank is reduced to a normal level, the ball valve is reset under the thrust of the second compression spring. At this time, the air pressure regulating relief valve is restored to the closed state.
Through screwing down or unscrewing the pressure regulating nut, the thrust of the second compression spring to the ball valve can be regulated, and therefore the air pressure threshold value is regulated. The pressure regulating nut is screwed up to improve the air pressure threshold, and the pressure regulating nut is unscrewed to reduce the air pressure threshold.
Example 3: referring to fig. 3, in the solar anti-freezing automatic water control system according to embodiment 2, a limiting device is fixed at the top of the ball valve; the limiting device comprises a limiting table 99 and a limiting column 910 fixed on the limiting table, the limiting table is fixed on the ball valve, and the bottom of the second compression spring is sleeved outside the limiting column and is limited by the limiting table.
The contact surface of the limiting table and the second compression spring is smooth, and the limiting column prevents the second compression spring from shaking in the radial direction, so that the second compression spring is more stable in stretching.
Example 4: referring to fig. 2, in the solar anti-freezing automatic water control system according to embodiment 1, a rubber block 66 is installed between the vertical portion of the elbow and the inner wall of the cylindrical valve body, the top end of the rubber block and the top end of the horizontal portion of the elbow are located at the same horizontal position, and the first compression spring is limited by the rubber block and the horizontal portion of the elbow.
The contact surface of the rubber block and the horizontal part of the elbow is larger than that of the first compression spring, so that the first compression spring is more stable in expansion and contraction.
Example 5: referring to fig. 2, in the solar anti-freezing automatic water control system according to embodiment 1, cap nuts 67 are screwed to the top and the bottom of the cylindrical valve body, and an opening at one end of each cap nut is sealed.
The top and bottom of the cylindrical valve body are sealed by cap nuts. When the internal components of the water control valve need to be maintained, only the cover-shaped nut needs to be dismounted, so that the water control valve is convenient to dismount.
Example 6: referring to fig. 2, in the solar anti-freezing automatic water control system according to embodiment 1, a sealing ring 10 is installed at an opening of the bottom of the cylindrical valve body through which a valve pull rod passes.
The sealing ring can prevent water in the cylindrical valve body from dripping into the water containing bucket in the water feeding process, the situation that the water control valve is closed when the water in the water tank is not filled with water is avoided, and the water control of the water control valve is more accurate.
Example 7: referring to fig. 1, in the solar anti-freezing automatic water control system according to embodiment 1, the tee is directly connected with the upper and lower water pipes, the hot water pipe and the cold water pipe through the external thread 11, and the water inlet and the water outlet of the cylindrical valve body are directly connected with the cold water pipe through the external thread.
The outer thread directly makes the connection between the pipe fittings more convenient, and the sealing effect is good.
Example 8: referring to fig. 1, in the solar anti-freezing automatic water control system according to embodiment 1, a faucet 12 is installed at a lower portion of the water containing barrel.
Through the arrangement of the water faucet, water in the water containing barrel can be discharged without taking down the water containing barrel.
Example 9: referring to fig. 1, in the solar anti-freezing automatic water control system according to embodiment 1, the water receiving device includes a water receiving bucket 13 and a hose 14, the water receiving bucket is disposed below the drain pipe, a water inlet end of the hose is connected to the water receiving bucket, and a water outlet end of the hose is disposed above the water containing bucket.
The water receiving hopper is used for collecting water flowing out of the exhaust pipe and flows into the water containing barrel through the hose. The positions of the water control valve and the water containing bucket can be set randomly, and the hose is only required to be placed above the water containing bucket.
Example 10: referring to fig. 4, in the solar anti-freezing automatic water control system according to embodiment 1, a part of the side edge of the water containing bucket is a plane.
Because the water control valve is installed on the wall, the water containing barrel is required to be arranged close to the wall, and the side edge of the plane of the water containing barrel faces the wall surface, so that the water containing barrel is more attached to the wall surface.
