Description

Technical Field

[0001] The utility model relates to the technical field of cooling tower equipment, in particular to a water replenishing device integrating manual and automatic operation. Background Art

[0002] Cooling towers are indispensable equipment in industrial production. Usually, the heat exchange of open cooling towers is through evaporation and heat dissipation through contact with the air. During this period, part of the circulating water will become water vapor and dissipate into the air. Therefore, the circulating water needs to be replenished in time during the operation of the circulating water. With the development of industry, large-scale open cooling towers are being used more and more, and the loss of circulating water in large cooling towers is also greater. The circulating water needs to be replenished in time during use.

[0003] Traditional water replenishment devices are usually single-type water replenishment, and the single-type automatic water replenishment of large cooling towers has a larger water volume, which requires a large-diameter float valve or several small-diameter float valves to work together. The large-diameter float valve ball is larger in size, which leads to a higher requirement for the depth of the cooling tower's sump; and with the combination of several small-diameter float valves, the single water replenishment method needs to increase the number of water replenishment ports, resulting in more water replenishment pipes that need to be connected, making the project complex and the operation complicated.

[0004] Therefore, a water replenishing device integrating manual and automatic functions is needed to solve the above problems. Utility Model Content

[0005] 1. Technical issues to be solved

[0006] The utility model provides a manual and automatic water replenishing device, aiming to solve the problem that the traditional water replenishing device mentioned in the background technology is usually a single water replenishing method, which is not only cumbersome to operate, but also inconvenient to use.

[0007] (II) Technical solution

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a water replenishing device integrating manual and automatic functions, comprising a water inlet main pipe connected to an external water inlet pipe, a T-shaped three-way pipe screwed on the end of the water inlet main pipe away from the external water inlet pipe, a float valve assembly arranged at one end of the T-shaped three-way pipe and placed in a cooling tower water tank, a manual ball valve arranged at the other end of the T-shaped three-way pipe, an elbow pipe arranged at one end of the manual ball valve away from the T-shaped three-way pipe, and a water guide pipe screwed on the end of the elbow pipe away from the manual ball valve and connected to the external water inlet pipe, wherein the manual ball valve and the float valve assembly are coaxially arranged; through the combined design of the water inlet main pipe, the elbow pipe, the water guide pipe, the T-shaped three-way pipe, the manual ball valve and the float valve assembly, the water replenishing of the cooling tower water tank liquid level can be automatically controlled by the float valve assembly under normal conditions, and when the float valve assembly replenishes water too slowly, it only needs to open the manual ball valve to combine with manual water replenishment to achieve rapid water replenishment, thereby improving the flexibility and reliability of water replenishment and being convenient and simple to operate.

[0009] To facilitate installation, direct joints are provided at both ends of the manual ball valve, and the two ends of the manual ball valve are respectively threadedly connected to the float valve assembly and the elbow pipe through the two direct joints; the design of the direct joint makes the connection between the manual ball valve, the float valve assembly and the elbow pipe simple and quick, reduces the special tools or equipment required during the installation process, and reduces the difficulty and cost of installation.

[0010] Preferably, in order to further improve the convenience of installation, a mounting plate connected to the cooling tower is fixedly mounted on the water inlet main pipe; the design of the mounting plate provides a special connection interface, so that the water inlet main pipe can be connected to the cooling tower more quickly and more firmly, simplifying the installation process.

[0011] Preferably, in order to achieve automatic control of the liquid level, the float valve assembly includes a valve body screwed to the end of the T-shaped three-way pipe away from the manual ball valve, a telescopic valve core slidably connected to the valve body, a connecting rod hinged on the valve body for driving the telescopic valve core to move, and a float fixedly connected to the end of the connecting rod away from the valve body, and the connecting rod and the float are both located in the cooling tower water tank; due to the linkage effect of the float and the connecting rod, the float valve assembly can automatically adjust the opening of the telescopic valve core according to changes in water level without manual intervention. This automated operation greatly reduces the burden on operators and improves work efficiency.

[0012] Preferably, in order to facilitate installation and maintenance, the interfaces of the straight joint and the elbow pipe are both national standard threaded interfaces; the national standard threaded interfaces have unified standards and specifications, making the connection process of the straight joint and the elbow pipe simple and quick. At the same time, the versatility of the national standard threaded interfaces makes it easy to replace or upgrade components during maintenance, thereby improving the adaptability and flexibility of the water replenishment device.

[0013] Preferably, for the convenience of connection, the elbow pipe is a 90-degree elbow; the design of the 90-degree elbow makes the connection between the elbow pipe and the straight head and the water pipe simpler and more convenient. At the same time, the 90-degree elbow can also be used to modify the direction of the pipeline to achieve the purpose of optimizing the fluid dynamic performance.

[0014] Preferably, in order to be flexible in opening and closing and easy to maintain, the manual ball valve is a national standard ball valve; the national standard ball valve has a wide range of diameters and can be applied to various pipeline systems.

[0017] The water replenishment device makes the connection between the manual ball valve, the float valve assembly and the elbow pipe simple and quick by providing a direct joint, reduces the special tools or equipment required during the installation process, and reduces the difficulty and cost of installation.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] The utility model provides a water replenishing device integrating manual and automatic functions. Figure 1-Figure 3 As shown, the water replenishment device includes a water inlet main pipe 1 connected to an external water inlet pipe, a T-shaped three-way pipe 2 screwed to the end of the water inlet main pipe 1 away from the external water inlet pipe, a float valve assembly 3 arranged at one end of the T-shaped three-way pipe 2 and placed in the cooling tower water tank, a manual ball valve 4 arranged at the other end of the T-shaped three-way pipe 2, an elbow pipe 5 arranged at the end of the manual ball valve 4 away from the T-shaped three-way pipe 2, and a water guide pipe 6 screwed to the end of the elbow pipe 5 away from the manual ball valve 4 and connected to the external water inlet pipe, the manual ball valve 4 and the float valve assembly 3 are coaxially arranged; both ends of the manual ball valve 4 are provided with direct joints 41, and the two ends of the manual ball valve 4 are screwed to the float valve assembly 3 and the elbow pipe 5 through two direct joints 41 respectively.

[0030] During use, under normal conditions, when the water level in the cooling tower water tank gradually decreases, the float valve assembly 3 will open. At this time, the water inlet pipe 1 connected to the external water inlet pipe will transport water to the cooling water tank for automatic water replenishment. When the water level reaches the set value, the float valve assembly 3 will automatically close and stop replenishing water. When the float valve assembly 3 is opened and the water replenishment speed is too slow, the operator can manually open the manual ball valve 4 at the same time. At this time, the external water source will be synchronously transported to the cooling tower water tank through the water inlet pipe 1, the elbow pipe 5 and the water guide pipe 6 for rapid water replenishment. When the water level reaches the set value, the float valve assembly 3 will automatically close, and the operator needs to manually close the manual ball valve 4. After manually closing the manual ball valve 4, it can be switched to a single automatic water replenishment mode under normal conditions.

[0031] Specifically, the float valve assembly 3 includes a valve body 31 screwed to the end of the T-shaped three-way pipe 2 away from the manual ball valve 4, a telescopic valve core slidably connected to the valve body 31, a connecting rod 32 hinged on the valve body 31 for driving the telescopic valve core to move, and a floating ball 33 fixedly connected to the end of the connecting rod 32 away from the valve body 31, and the connecting rod 32 and the floating ball 33 are both located in the cooling tower water tank;

[0032] When the water level in the cooling tower water tank drops, the float 33 placed in the cooling tower water tank will drop with the drop of the water level. Since the float 33 is connected to the connecting rod 32, when the float 33 drops, the connecting rod 32 will move downward synchronously and pull the telescopic valve core to open the valve. As the valve gradually opens, the external water source can flow from the water inlet main pipe 1 through the T-shaped three-way pipe 2 and the float valve assembly 3 into the cooling tower water tank for automatic water replenishment. When the liquid level in the cooling tower water tank rises, the float 33 will rise accordingly. When the float 33 rises with the increase of the liquid level, the connecting rod 32 will push back the telescopic valve core and gradually close the valve. After the valve is completely closed, the water replenishment process stops and the water level in the cooling tower water tank is maintained.

[0033] Furthermore, a mounting plate 11 connected to the cooling tower is fixedly mounted on the water inlet pipe 1; the mounting plate 11 is first fixed to a suitable position of the cooling tower by welding or other means, and then one end of the water inlet pipe 1 is passed through the reserved hole of the mounting plate 11 and fixed by welding or other means to ensure that the water inlet pipe 1 is tightly fitted to the mounting plate 11, thereby achieving a stable installation of the water inlet pipe 1.

[0034] Among them, in order to facilitate installation and maintenance, the interfaces of the straight connector 41 and the elbow pipe 5 are both national standard threaded interfaces; the national standard threaded interfaces have unified standards and specifications, making the connection process of the straight connector 41 and the elbow pipe 5 simple and quick. At the same time, the versatility of the national standard threaded interfaces makes it easy to replace or upgrade components during maintenance, thereby improving the adaptability and flexibility of the water replenishment device.

[0035] In addition, for the convenience of connection, the elbow pipe 5 is a 90-degree elbow; the design of the 90-degree elbow makes the connection between the elbow pipe 5 and the straight joint 41 and the water pipe 6 simpler and more convenient. At the same time, the 90-degree elbow can also be used to modify the direction of the pipeline to achieve the purpose of optimizing the fluid dynamic performance.

[0036] Furthermore, in order to be flexible in opening and closing and easy to maintain, the manual ball valve 4 is a national standard ball valve; the national standard ball valve has a wide range of diameters and can be applied to various pipeline systems. At the same time, the structure of the national standard ball valve is relatively simple and easy to operate.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
