[0026] Embodiments of the present application are described in detail below with reference to the accompanying drawings. The embodiments described below are exemplary and are intended to explain the present application, and are not to be understood as limiting the present application.

[0027] The industrial circulating water supply and return pipeline system according to the embodiments of the present application is arranged on the equipment body 1 and comprises a water supply pipe 2, a water return pipe 3, a buffer assembly and a first valve 4. The water supply pipe 2 is connected to the water inlet of the equipment body 1, and the water return pipe 3 is connected to the water outlet of the equipment body 1. The first valve 4 is arranged on the water supply pipe 2. The buffer assembly is arranged at the end of the water supply pipe 2 away from the first valve 4 and the equipment body 1. The buffer assembly comprises a side pipe 5, a shock-absorbing cylinder 6 and a damping member. The side pipe 5 is connected to the shock-absorbing cylinder 6 and the water supply pipe 2, respectively. The damping member seals the inlet of the shock-absorbing cylinder 6, and the damping member extends or contracts in the extension direction of the shock-absorbing cylinder 6.

[0028] The industrial circulating water supply and return pipeline system according to the embodiments of the present application can buffer the water pressure of the pipeline, thereby reducing the damage of water flow impact to the pipeline and the valve.

[0029] Specifically, as shown in Figure 1 and Figure 2 , the equipment body 1 is provided with the water supply pipe 2 and the water return pipe 3. One end of the water supply pipe 2 is connected to the water supply system to supply water to the equipment body 1. The inlet of the water return pipe 3 is connected to the water outlet of the equipment body 1 to return water to the water supply system. One end of the side pipe 5 is connected to the water supply pipe 2, and the other end of the side pipe 5 is connected to the shock-absorbing cylinder 6.

[0030] In a low-temperature environment, the flexibility of the pipeline material decreases significantly, the pipeline becomes fragile, and is easily impacted by water hammer effect when the water flow is interrupted or the valve is opened and closed. The shock-absorbing assembly is arranged on the water supply pipe 2, and the shock-absorbing assembly is arranged at the end of the water supply pipe 2 away from the first valve 4 and the equipment body 1, so as to reduce the pressure impact generated by water flow fluctuation or valve action on the pipeline and its connection when the first valve 4 is closed, thereby reducing the damage risk of the pipeline and the valve, and significantly prolonging the service life of the entire pipeline system.

[0031] The damping member seals the inlet of the shock-absorbing cylinder 6, and the damping member contracts and extends in the extension direction of the shock-absorbing cylinder 6 to buffer the water flow impact when the valve is closed. The damping member can absorb and disperse these impact forces through its damping effect, thereby protecting the pipeline system and the equipment from damage.

[0032] The industrial circulating water supply and return pipeline system of the embodiment of the present application can buffer the water pressure of the pipeline by setting the buffer assembly on the water supply pipe 2, and the damping component contracts and expands in the extension direction of the damping cylinder 6 to buffer the water flow impact when the valve is closed, and the damping component can absorb and disperse these impact forces through its damping effect, thereby protecting the pipeline system and equipment from damage and reducing the damage of water flow impact on the pipeline and valve.

[0033] In some embodiments, the damping component includes a piston 601, a spring 602 and a damping piece 603, the piston 601 is connected with the damping piece 603, the piston 601 is arranged on the inlet side of the damping cylinder 6,

[0034] The piston 601 and the damping cylinder 6 form a damping chamber, the spring 602 and the damping piece 603 are arranged in the damping chamber, and the spring 602 is sleeved on the damping piece 603, one end of the spring 602 abuts against the piston 601, and the other end of the spring 602 abuts against the inner wall of the damping chamber. The upper end of the piston 601 is connected with the lower end of the damping piece 603, the upper end of the damping piece 603 is in contact with the inner wall of the damping chamber, and then the upper end of the damping piece 603 is in contact with or connected with the upper wall of the damping chamber, so as to install the damping component in the damping chamber. The upper end of the piston 601 closes the outlet of the damping chamber to prevent the water in the water supply pipe 2 from entering the damping cylinder 6, and the piston 601 always keeps the outlet of the damping chamber closed during the expansion or contraction of the damping component in the up-down direction.

[0035] The piston 601 is movably installed in the damping cylinder 6, and the cooperation of the damping piece 603 and the spring 602 is connected, so as to realize the buffering of the water flow pressure to the pipeline. When the water flow enters the damping cylinder 6 through the side pipe 5, the piston 601 is pushed upward, and the spring 602 plays a buffering role in this process, can absorb and disperse the pressure generated by the water flow impact, avoid the direct impact of the pipeline by the high-pressure water flow, and the inflation valve 604 at the top end of the damping cylinder 6 allows the user to adjust the gas pressure in the cylinder according to the needs, further fine-tune the damping effect, to adapt to the pressure demand in different working environments.

[0036] Specifically, as shown in Figure 1 and Figure 2 , the spring 602 is compressed under the impact of the water flow during the opening or closing of the valve to buffer the water, and by setting the spring 602 and the damping piece 603, the water flow impact can be buffered, that is, the spring 602 is contracted to buffer when the valve is closed, and the damping piece 603 contracts and expands to consume the elastic potential energy of the spring 602 and slow down the speed of the piston 601 moving up and down, reduce the impact force of the damping component on the water flow after the water flow impact, and then increase the service life and stability of the pipeline.

[0037] In some embodiments, the industrial circulating water supply and return pipeline system further comprises an air charging valve 604 door, which is arranged on the damping cylinder 6 and communicates with the damping chamber. The damping chamber can be filled with gas through the air charging valve 604 door, and the damping chamber is provided with gas to buffer the upward movement of the piston 601, and further buffer the impact force received by the piston 601.

[0038] Further, the industrial circulating water supply and return pipeline system further comprises a pressure monitoring member 605 connected with the damping cylinder 6 to monitor the pressure of the damping chamber. Further, by monitoring the pressure in the damping chamber, it is determined whether to charge or discharge the gas in the damping chamber to adjust the amount of gas in the damping chamber.

[0039] Further, the air charging valve 604 at the top end of the damping cylinder 6 allows the user to adjust the gas pressure in the cylinder as needed, and further fine-tune the damping effect to meet the pressure requirements in different working environments.

[0040] In some embodiments, the industrial circulating water supply and return pipeline system further comprises a bypass pipe 7 and a second valve 8, the inlet of the bypass pipe 7 is connected with the water supply pipe 2, the outlet of the bypass pipe 7 is connected with the water return pipe 3, and the inlet and the outlet of the bypass pipe 7 are both provided with the second valve 8.

[0041] Specifically, as shown in Figure 1 and Figure 2 By arranging the second valve 8, the bypass pipe 7 can be opened or closed at any time. When the device body 1 stops running or is being maintained, the second valve 8 is opened, so that the water of the water supply system bypasses the device body 1, and the water is circulated to avoid freezing of the water body. A kind of anti-freezing mechanism when the device body 1 stops running is realized, when the device does not work, the second valve 8 can be opened, so that a direct communication path is formed between the water supply pipe 2 and the water return pipe 3, which constitutes a circulating water system independent of the internal process of the device body 1, ensures that the cooling water can continuously flow in the entire system, effectively avoids the freezing problem that can be caused by static.

[0042] Further, the industrial circulating water supply and return pipeline system further comprises a water outlet valve connected with the bypass pipe 7. The water outlet valve is suitable for draining the water in the water supply pipe 2, the return pipe 3 and the bypass pipe 7, that is, when the device body needs to be overhauled or closed, the first valve 4 arranged on the outer surface of the water supply pipe 2 and the return pipe 3 is closed, and the second valve 8 arranged on the outer surface of the two ends of the bypass pipe 7 is opened, so that the cooling water bypasses the device body through the bypass pipe 7, avoiding the cooling water from freezing in the water supply pipe 2 and the return pipe 3. Secondly, when the cooling water in the water supply pipe 2 flows into the damping cylinder 6 through the side pipe 5, it pushes the piston 601 to move upwards, and through the quota of the spring 602 and the extension rod, it can absorb and disperse the pressure generated by the water flow impact, thereby avoiding the direct impact of the high-pressure water flow on the water supply pipe 2. In addition, the inflation valve 604 at the top end of the damping cylinder 6 can adjust the gas pressure in the cylinder according to the needs, and the water supply pipe 2 can adapt to the pressure demand in different working environments, meeting the needs of the workers.

[0043] Further, the first valve 4 is arranged on the return pipe 3 between the outlet of the device body 1 and the bypass pipe 7. So as to close the water circulation of the device body 1 when the device body 1 is overhauled or shut down.

[0044] Further, the bypass pipe 7 is arranged on the side of the water supply pipe 2 away from the buffer assembly and the first valve 4. Specifically, as shown in Figure 1 and Figure 2 After the first valve 4 is closed, the device body 1 can be completely isolated from the water circulation of the water supply system, avoiding the water from entering the device body 1 and causing the water in the device body 1 to freeze.

[0045] In some embodiments, the number of buffer assemblies is multiple, and each of the multiple buffer assemblies is connected with the water supply pipe 2. The number of buffer assemblies can be increased or decreased according to actual conditions,

[0046] In some embodiments, the return pipe 3 is provided with a buffer assembly. Thus, the water flow in the return pipe 3 can be buffered when the valve is closed,

[0047] The industrial circulating water supply and return pipeline system can make water flow continue to circulate without passing through the equipment main body 1, solves the problem of water freezing, also ensures stable operation of the system during shutdown and maintenance, meets the demand of the staff, saves engineering cost and operation and maintenance cost, simultaneously, without needing electric heat tracing and insulation layer to be arranged on the return pipe 3 or the water supply pipe 2, the water flow in the pipeline is ensured, the engineering cost and power consumption are saved, through cooperation of the piston 601, the damping piece 603 and the spring 602 arranged in the shock absorbing cylinder 6, impact force generated when the first valve 4 is closed can be greatly absorbed and dispersed, damage of the pipeline connection part when the first valve 4 is closed is effectively avoided, the service life of the pipeline is prolonged, and the engineering cost and operation and maintenance cost are saved.
