Description

Technical Field

[0001] The utility model relates to the technical field of water inlet devices, in particular to a water tank water inlet device. Background Art

[0002] The water supply pump room is composed of water supply pumps and their supporting facilities, and is used for boosting water supply and replenishment for life, process and waterscape. At present, the mainstream water inlet of the water tank in the domestic water supply pump room adopts remote control float valve, which is mainly composed of main valve and small float pilot valve, etc., used for water level control, and is often used for water level control of large pipe diameter. According to the different valve body materials, it can be divided into cast iron valve, stainless steel valve, etc. When the water level in the water tank rises, the small float drives the pilot valve stem to rise. When the water level reaches the set water level of the installation height, the float pilot valve closes, the water pressure in the main valve control chamber increases, and the main valve is pushed to close and the water supply is stopped. When the water level drops, the float pilot valve drops, the pilot valve discharges water, the water pressure in the control room drops, and the main valve opens to supply water again.

[0003] A purely mechanical remote-controlled float valve that is not used synchronously with an electric valve, in which the float switch is a simple passive device, has a high failure rate when the real-time water replenishment of the water tank is frequent, and staff are required to perform high-frequency inspections and maintenance. When the float switch is damaged, it is easy to cause the main valve to continue to replenish water and overflow, thereby wasting water resources, or directly causing the ball valve to become clogged, which in turn causes the main valve to stop taking in water. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a water tank water inlet device.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a water tank water inlet device, comprising a large water tank with an opening at the upper end, a support plate fixed on the side wall of the large water tank, a small water tank installed on the upper surface of the support plate, an exhaust valve arranged on the upper surface of the small water tank, a first connecting pipe connected to the exhaust valve, the other end of the first connecting pipe extending into the large water tank, a second connecting pipe connected to the bottom of the small water tank, the other end of the second connecting pipe being interconnected with the lower end of the side wall of the large water tank, a float valve arranged in the small water tank, a main valve connected to the float valve, and a conduit for water inlet connected to the main valve.

[0006] By adopting the above technical scheme, the water inlet device involved in this product is based on the existing remote control float valve, and cooperates with the external closed small water tank of the large water tank (made of stainless steel, with an exhaust valve on the top and a small float inside), and also includes a DN15 stainless steel connecting pipe connecting the large and small water tanks. This connecting pipe is connected to the pipe section before the exhaust valve, and the other end is connected above the overflow water level of the large water tank. The bottom port is set between the lowest and highest water levels according to the actual situation. The original small float is directly set in the large water tank. When the water inflow is violent, it is greatly disturbed by the water level fluctuation, and the liquid level difference formed in this situation is negligible, which is almost real-time water replenishment. When there is not much water shortage, it needs to be opened again. The action frequency is too high in a short time, which accelerates the damage of the float. This device can effectively avoid such problems, protect the normal operation of the small float, and extend the water inlet time difference by setting the liquid level difference in the large water tank, and simultaneously extend the normal service life of the small float.

[0007] Furthermore, the first connecting pipe is a first connecting pipe made of DN15 stainless steel, and the second connecting pipe is a second connecting pipe made of DN25 stainless steel.

[0008] By adopting the above technical solution, the working principle of this device is to use a simple siphon liquid level difference to control the water inlet of the water tank. The device is a water tank water inlet device. Its principle is that during the water tank replenishment stage, the large and small water tanks achieve liquid level balance through the second connecting pipe. However, since the small water tank is a closed water tank, the air on the top of the small water tank must be discharged through the exhaust valve on the top when the water level rises, so that the liquid level balance of the large and small water tanks can be achieved. At the same time, when the water level is higher than the bottom of the first connecting pipe, the air in the first connecting pipe is also discharged synchronously with the small water tank as the liquid level in the large water tank rises. Finally, the float in the small water tank floats up to close the main valve, and the controlled water level is the same as the highest liquid level of the large water tank.

[0009] When the water in the large water tank begins to be used by users, the liquid level drops. However, at this time, the liquid level in the small water tank and the first connecting pipe are still under negative pressure due to the siphon principle, thus keeping the float inactive. When the water level drops to the lowest point of the first connecting pipe, the siphon effect is broken, and the first connecting pipe indirectly starts to replenish air into the closed small water tank. The float drops and the main valve opens to continue replenishing water. The height difference from the highest water level to the lowest point of the first connecting pipe is the liquid level difference of the float action, and the time when the liquid level drops is also the time when the float remains inactive. This device greatly reduces the frequency of the float action and can achieve continuous water replenishment of the float.

[0010] Furthermore, a fixing plate is fixed to the bottom surface of the support plate, and the fixing plate and the side wall of the large water tank are fixed to each other, and the angle between the fixing plate and the support plate is 60 degrees.

[0011] By adopting the above technical solution, a triangular structure is formed between the fixing plate, the supporting plate and the side wall of the large water tank, which is beneficial to improving the stability of the fixing plate and further improving the stability of the small water tank.

[0012] Furthermore, the second connecting pipe is connected to a third connecting pipe, and the third connecting pipe is provided with a control valve for controlling the opening and closing of the third connecting pipe.

[0013] By adopting the above technical solution, when the staff needs to release the water in the small water tank, the staff only needs to open the control valve to allow the water to be discharged through the second connecting pipe and the third connecting pipe, thereby reducing the operating difficulty of the staff.

[0014] Furthermore, the third connecting pipe is made of DN15 stainless steel.

[0015] By adopting the above technical solution, the device uses the siphon phenomenon to flow water from high to low, thereby realizing the "automatic" control of water inlet into the water tank. The technical solution mainly consists of a closed small water tank, an exhaust valve, and a connecting pipe. It does not require any electric equipment and can set the liquid level difference according to the actual situation in the initial stage.

[0016] In this technical solution, the large and small water tanks are where water is stored, the water inlet pipe transports water to the small water tank, the exhaust valve is responsible for exhausting the air in the system, maintaining negative pressure to achieve the siphon function, and the siphon pipe is used to timely allocate water and air from the large and small water tanks without human intervention. When the water level drops to a certain level, the system will automatically start the water inlet device to transport water to the water tank, thereby maintaining a stable water level.

[0017] Furthermore, a connecting rod is fixed on the side wall of the small water tank close to the large water tank, and the other end of the connecting rod is welded and fixed to the large water tank.

[0018] By adopting the above technical solution, the stability of the small water tank is further improved, thereby reducing the probability of the small water tank shaking when replenishing water, thereby reducing the probability of the small water tank making noise.

[0019] Furthermore, the height difference between the bottom port of the second connecting pipe and the bottom port of the first connecting pipe is 30 cm.

[0020] Furthermore, the first connecting pipe penetrates the side wall of the large water tank and is slidably connected.

[0021] By adopting the above technical solution, the stability of the first connecting pipe is improved, thereby reducing the probability of the first connecting pipe hitting the large water tank multiple times in a short period of time, thereby improving the user experience of the staff.

[0022] In summary, the utility model has the following beneficial effects:

[0023] 1. In this application, the water inlet device involved in this product is based on the use of the existing remote control float valve, and is equipped with an external closed small water tank (made of stainless steel, with an exhaust valve on the top and a small float inside) of the large water tank. It also includes a DN15 stainless steel connecting pipe connecting the large and small water tanks. This connecting pipe is connected to the pipe section in front of the exhaust valve, and the other end is connected above the overflow water level of the large water tank. The bottom port is set between the lowest and highest water levels according to actual conditions. The original small float is directly set in the large water tank. When the water inflow is violent, it is greatly disturbed by the water level fluctuation, and the liquid level difference formed in this situation is negligible, which is almost real-time water replenishment. When there is a small amount of water shortage, it has to be opened again. The action frequency is too high in a short period of time, which accelerates the damage of the float. This device can effectively avoid such problems and protect the normal operation of the small float. By setting the liquid level difference in the large water tank, the water inlet time difference is extended, and the normal service life of the small float is extended simultaneously;

Finally, the float in the small water tank floats up to close the main valve, and the controlled water level is the same as the highest liquid level in the large water tank;

[0025] When the water in the large water tank begins to be used by users, the liquid level drops.

The large water tank 1 is a rectangular parallelepiped structure with an upper end opening, and the support plate 11 is a rectangular plate-shaped structure, and the support plate 11 is fixed on the side wall of the large water tank 1.

[0034] The first connecting pipe 3 is made of DN15 stainless steel, and the second connecting pipe 31 is made of DN25 stainless steel.

[0035] The working principle of this device is to use a simple siphon liquid level difference to control the water inlet of the water tank. The device is a water tank water inlet device. Its principle is that during the water tank replenishment stage, the large and small water tanks 2 achieve liquid level balance through the second connecting pipe 31. However, since the small water tank 2 is a closed water tank, the air on the top of the small water tank 2 must be discharged through the exhaust valve 21 at the top when the water level rises, so that the liquid level balance of the large and small water tanks 2 can be achieved. At the same time, when the water level is higher than the bottom of the first connecting pipe 3, the air in the first connecting pipe 3 is also discharged synchronously with the small water tank 2 as the liquid level in the large water tank 1 rises. Finally, the float in the small water tank 2 floats up to close the main valve 41, and the controlled water level is the same as the highest liquid level of the large water tank 1.

[0036] When the water in the large water tank 1 begins to be used by users, the liquid level drops. However, at this time, the liquid level in the small water tank 2 and the first connecting pipe 3 are still under negative pressure due to the siphon principle, thereby keeping the float inactive. When the water level drops to the lowest point of the first connecting pipe 3, the siphon effect is broken, and the first connecting pipe 3 indirectly starts to replenish air into the closed small water tank 2. The float drops and the main valve 41 is opened synchronously to continue replenishing water. The height difference from the highest water level to the lowest point of the first connecting pipe 3 is the liquid level difference of the float action, and the time for the liquid level to drop is also the time for the float to remain inactive. This device greatly reduces the frequency of the float action and can achieve continuous water replenishment of the float.

[0037] The fixing plate 6 is a plate-shaped structure, fixed to the bottom surface of the supporting plate 11, the fixing plate 6 and the side wall of the large water tank 1 are fixed to each other, and the angle between the fixing plate 6 and the supporting plate 11 is 60 degrees.

[0039] The third connecting pipe 7 is a circular tube structure, connected to the second connecting pipe 31, and made of DN15 stainless steel. The control valve 8 is arranged on the third connecting pipe 7 to control the opening and closing of the third connecting pipe 7.

[0040] When the staff needs to release the water in the small water tank 2, the staff only needs to open the control valve 8 to allow the water to be discharged through the second connecting pipe 31 and the third connecting pipe 7, thereby reducing the operating difficulty of the staff.

[0041] This device uses the siphon phenomenon to make water flow from high to low, thereby realizing the "automatic" control of water inlet into the water tank. The technical solution mainly consists of a closed small water tank 2, an exhaust valve 21, and a connecting pipe. It does not require any electric equipment and can set the liquid level difference according to the actual situation in the initial stage.

[0042] In this technical solution, the large and small water tanks 2 are places for storing water sources, the water inlet pipe transports the water source to the small water tank 2, the exhaust valve 21 is responsible for exhausting the air in the system, maintaining negative pressure to achieve the siphon function, and the siphon pipe is used to timely allocate water and air from the large and small water tanks 2 without human intervention. When the water level drops to a certain level, the system will automatically start the water inlet device to transport the water source to the water tank, thereby maintaining the stability of the water level.

[0043] The connecting rod 9 is a rod-shaped structure, and the connecting rod 9 is fixed to the side wall of the small water tank 2 close to the large water tank 1, and the other end of the connecting rod 9 is welded and fixed to the large water tank 1. The connecting rod 9 further improves the stability of the small water tank 2, thereby reducing the probability of shaking of the small water tank 2 when replenishing water, thereby reducing the probability of the small water tank 2 making noise.

[0044] In order to improve the user experience of the staff, the height difference between the bottom port of the second connecting pipe 31 and the bottom port of the first connecting pipe 3 is 30 cm, and the first connecting pipe 3 penetrates the side wall of the large water tank 1 and is slidably connected. Such a setting improves the stability of the first connecting pipe 3, thereby reducing the probability of the first connecting pipe 3 hitting the large water tank 1 multiple times in a short period of time, thereby improving the user experience of the staff.

[0045] The use principle of a water tank water inlet device in this embodiment is as follows: the water inlet device involved in this product is based on the use of the existing remote control float valve 4, and cooperates with the external closed small water tank 2 (stainless steel material, with an exhaust valve 21 on the top and a small float inside) of the large water tank 1, and also includes a DN15 stainless steel connecting pipe connecting the large and small water tanks 2, the connecting pipe is connected to the front pipe section of the exhaust valve 21, and the other end is connected above the overflow water level of the large water tank 1, and the bottom port is set between the lowest and highest water levels according to the actual situation.
