Description

Technical Field

[0001] The invention relates to the technical field of liquid level float valves, in particular to a float valve system for accurately and automatically controlling liquid levels. Background Art

[0002] With the rapid development of modern industrial technology, refrigeration machines and refrigeration equipment are increasingly used in various fields, from food processing to pharmaceutical manufacturing, from data center cooling to cold chain logistics. The efficient and stable operation of these equipment is crucial to ensuring production quality and efficiency. Among the core components of refrigeration machines and refrigeration equipment, the liquid level control system plays a pivotal role. In the field of modern industrial refrigeration, refrigeration machines and refrigeration equipment are key equipment for maintaining low-temperature environments and ensuring stable operation of production processes. The accuracy and reliability of their internal liquid level control systems are crucial. The float valve system, as a liquid level automatic adjustment device widely used in such equipment, is connected to the gear set through a precisely designed connecting rod mechanism. When the liquid level changes, the rise and fall of the float will drive the gear set to perform precise transmission. However, with the continuous advancement of technology and the increasing complexity of industrial needs, the traditional float valve system has gradually exposed some shortcomings and disadvantages in structural design and practical applications.

[0003] In the existing float valve system, the connecting rod mechanism is a key component connecting the float and the valve core. Its structure is complex and easily affected by external forces such as vibration and impact, which can easily cause the connecting rod to loosen, break or wear, affecting the stability and reliability of the system. Secondly, the float valve system has many internal components, and most of them are located in difficult-to-reach places inside the equipment. Once a failure occurs, repair and replacement work is often complicated and time-consuming, increasing equipment downtime and maintenance costs. Summary of the invention

[0004] The invention provides a float valve system for accurately and automatically controlling liquid level, which solves the problems of insufficient reliability of a connecting rod mechanism and great maintenance difficulty in the existing float valve system for accurately and automatically controlling liquid level.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A float valve system for accurately and automatically controlling liquid level comprises a tank body, a support seat is arranged below the tank body, flanges are arranged on both sides of the tank body, a detachable circular cover is arranged on the outside of the tank body, threaded holes matching the flanges are arranged on the outside of the circular cover, the circular cover is connected to the flanges by bolts, a sensor is arranged below the inside of the tank body, slots are arranged on both sides of the sensor, a baffle is arranged on the top of the outside of the tank body, through holes are arranged on both sides of the baffle, and the through holes run through the inside of the tank body, a valve stem matching the slots is arranged inside the through hole, a float and a slide rod are sleeved on the outside of the valve stem, and a connecting rod mechanism is arranged above the valve stem and located on the outside of the top of the tank body.

[0007] Preferably, a water outlet is provided at the bottom of the support seat below the tank body, and a water inlet is provided on the side of the tank body.

[0008] Preferably, knob valves are provided on the outsides of the water outlet and the water inlet.

[0009] Preferably, a mounting seat is provided on the outer side of the top of the tank body above the through hole, and a reset groove is provided inside the mounting seat, the valve stem is connected to the top of the reset groove, and a first reset spring is provided inside the reset groove on the outer side of the valve stem.

[0010] Preferably, a U-shaped pressure plate is provided below the first return spring, and the U-shaped pressure plate is located above the float and the slide rod, and the U-shaped pressure plate is movably connected to the inside of the mounting seat via a rotating shaft.

[0011] Preferably, the connecting rod mechanism includes a boss, a mounting groove, a slide, a connecting rod, and a second return spring, and the side of the baffle is provided with a boss, the top of the boss is provided with a mounting groove, and the side of the mounting groove is provided with a slide, and the inside of the mounting groove is provided with a connecting rod matching the slide in a movably connected manner.

[0012] Preferably, a second return spring is arranged inside the installation groove below the connecting rod, and the connecting rod is located below the U-shaped pressure plates on both sides to form a connecting structure.

[0013] A control system for a float valve system for accurately and automatically controlling a liquid level comprises the following steps:

[0014] S1. Check the flanges and bolts on both sides of the tank body. The float and slide rod on the outside of the valve stem inside the tank body rise and fall with the change of water level by utilizing the buoyancy of the float in the water.

[0015] S2. When the liquid level rises, the float rises accordingly, and the slide rod extends upward to drive the inside of the mounting seat, and the U-shaped pressure plate connected by the rotating shaft moves. The U-shaped pressure plate drives the connecting rod to move, and the connecting rod controls or drives the gear set to perform precise transmission;

[0016] S3. On the contrary, when the liquid level drops, the float drops accordingly, and the connection structure is reset by the elastic action of the first reset spring and the second reset spring;

[0017] S4. The internal sensor of the tank is integrated with a remote monitoring and fault diagnosis module to monitor the system operation status in real time to avoid failures or abnormal situations such as float jamming, gear set damage, and further improve the accuracy of automatic control of the liquid level float valve.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. In the float valve system for precise automatic control of liquid level, a U-shaped pressure plate is located above the float and the slide rod, a U-shaped pressure plate is arranged below the first return spring, and a U-shaped pressure plate is arranged above the connecting rod, which simplifies the connecting rod structure, reduces unnecessary transmission links, and improves transmission efficiency. At the same time, the use of high-strength and wear-resistant materials enhances the stability of the connecting rod structure and ensures precise automatic control. Secondly, the U-shaped pressure plate is connected to the inside of the mounting seat through a rotating shaft, which strengthens the stability and protection measures of the structure, enhances its anti-vibration and anti-impact capabilities, ensures control accuracy, and reduces external interference.

[0020] 2. The outer side of the circular cover of the present invention is provided with threaded holes matching the flange, and is connected to the flange by bolts, which is convenient for quick disassembly and maintenance. At the same time, a sensor is provided at the lower part of the tank body, integrating a remote monitoring and fault diagnosis module to monitor the system operation status in real time, timely discover and handle potential faults, and reduce maintenance difficulty and downtime.

[0021] 3. The present invention adopts a double float valve in the tank body, which improves the system's perception of liquid level changes, improves the adjustment accuracy, and ensures the stability of operation by reducing the volume of the float, optimizing the shape of the float, increasing the number of floats, and coordinating sensor-assisted detection. Secondly, this precise liquid level control method not only ensures the stable operation of the refrigeration system, but also significantly improves the refrigeration efficiency and reduces energy consumption.
