Description

Technical Field

[0001] The utility model relates to the technical field of pipeline water hammer protection equipment, in particular to a water replenishment release tank. Background Art

[0002] In a pressurized water supply system, an inner tank air pressure tank is often installed to eliminate the positive and negative pressure wave water hammer generated by the water flowing in the pipeline.

[0003] When the pipeline is under negative pressure, the stored water in the inner tank will quickly flow back to the main pipeline to balance the negative pressure. When the pipeline generates positive pressure wave water hammer, the high-pressure water head first compresses the gas in the inner tank, so that the positive pressure wave water hammer can be buffered and reduced. When the reserved gas compression volume is insufficient, it is often necessary to release the pressure through an ordinary safety valve installed on the top of the tank to ensure the elimination of the positive pressure wave water hammer. However, this safety valve has its limitations. Due to the small flow area and insufficient discharge flow, it can only be used on pressure vessels with fixed capacity. However, large-diameter and long-distance water transmission conditions require a large-flow sustainable water discharge and pressure relief device to ensure that the main pipeline will not continue to increase pressure or superimpose pressure.

[0020] The following is a detailed description of the embodiments of the utility model in conjunction with the accompanying drawings. It should be clear that the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0021] like Figure 1-4 As shown, in some illustrative embodiments, a water replenishment release tank is provided, comprising: an inner liner air pressure tank 1 and a direct-acting overpressure releaser 2 arranged on the top of the inner liner air pressure tank 1.

[0022] A rubber liner 101 is arranged in the tank body of the liner pressure tank 1. An air filling nozzle 102 is arranged on the liner pressure tank, and the rubber liner 101 is inflated through the air filling nozzle 102.

[0023] The top of the inner liner air pressure tank 1 is provided with a releaser water port 103 for connecting to the direct-acting overpressure releaser 2, and the side of the lower half of the inner liner air pressure tank 1 is provided with a main pipeline water port 104 for connecting to the main pipeline.

[0024] When positive pressure wave water hammer occurs in the main pipeline, high pressure water enters the inner tank air pressure tank 1 through the main pipeline water port 104. The direct-acting overpressure releaser 2 is arranged on the top of the inner tank air pressure tank 1. When the reserved gas compression volume is insufficient, the direct-acting overpressure releaser 2 installed on the tank top releases the remaining pressure to ensure the effective elimination of positive pressure wave water hammer.

[0025] The rubber liner 101 is filled with air or nitrogen. When the high-pressure water head flows into the tank, the gas in the rubber liner 101 is first compressed, so that the positive pressure wave water hammer can be buffered and reduced. The water inlet of the direct-acting overpressure releaser 2 is connected to the releaser water port 103 of the inner liner air pressure tank 1, that is, the high-pressure water flowing out of the inner liner air pressure tank 1 flows into the direct-acting overpressure releaser 2.

[0026] The direct-acting overpressure releaser 2 comprises: a housing 201, a cover plate 202, an L-shaped water outlet pipe 203 and an adjusting mechanism.

[0027] The water inlet 210 of the direct-acting overpressure releaser is provided at the bottom of the housing 201. A mounting groove 204 is provided at the top of the housing 201, and the adjustment mechanism is arranged in the mounting groove 204. A through hole is provided on the side of the housing 201. The top water inlet 203a of the L-shaped water outlet pipe 203 is located in the housing 201 and below the adjustment mechanism, and the side water outlet 203b of the L-shaped water outlet pipe 203 extends from the through hole.

[0028] The water inlet 210 of the water automatic direct-acting overpressure releaser enters the interior of the housing 201. When the internal water pressure exceeds the pressure, the cover plate 202 is pulled up by the adjustment mechanism, and the water flows from the bottom of the L-shaped water outlet pipe 203 along the flow channel between the L-shaped water outlet pipe 203 and the inner wall of the housing to the top of the L-shaped water outlet pipe 203, and flows into the top water inlet 203a to complete the pressure relief until the cover plate 202 falls. The above structural design is more reasonable, so that the water flow will not cause a large impact on the overpressure relief device, thereby extending the overall operation time and making the structure more stable.

[0029] The cover plate 202 is connected to the adjustment mechanism.

[0030] The regulating mechanism includes: a piston cylinder 501 , a diaphragm 502 , a connecting rod 503 , a spring 504 , an upper cover 505 , an regulating rod 506 , and a diaphragm pressing plate 507 .

[0031] The upper cover 505 is installed on the top of the housing 201 by bolts, the adjusting rod 506 is threadedly connected to the upper cover 505, one end of the spring 504 is connected to the adjusting rod 506, and the other end is connected to the piston cylinder 501. When the adjusting rod 506 is turned, the length of the adjusting rod 506 extending into the upper cover 505 can be adjusted, thereby adjusting the force applied by the spring 504 to the piston cylinder 501. The piston cylinder 501 is arranged in the installation groove 204 and can move up and down along the installation groove 204 and the internal space of the upper cover 505.

[0032] The diaphragm 502 is arranged at the notch of the mounting groove 204 and seals the mounting groove 204. The cover plate 202 is connected to the piston cylinder 501 through the connecting rod 503. The diaphragm pressure plate 507 is arranged at the bottom of the piston cylinder 501, and the middle part of the diaphragm 502 is clamped between the piston cylinder 501 and the diaphragm pressure plate 507.

[0033] When the water in the housing 201 pushes the diaphragm pressing plate 507 upward, the spring 504 provides a reaction force to the diaphragm pressing plate 507. By adjusting the length of the adjusting rod 506, the distance between the top of the spring 504 and the lower surface of the upper cover 505 can be adjusted, thereby adjusting the reaction force applied by the spring 504 to the diaphragm pressing plate 507 under the same displacement, thereby adjusting the pressure relief value.

[0034] The specific working process of this utility model is as follows:

[0035] When the water from the inner tank air pressure tank 1 fills the entire internal space of the direct-acting overpressure releaser 2, the pressure of the water in the outer shell in all directions is equal, and the sum of the deadweight of each structure and the pressure generated by the spring 504 is greater than the force exerted by the water on the diaphragm pressure plate 507. At this time, the cover plate 202 and the top water inlet 203a are tightly combined and in a balanced state, the valve port does not flow, and no water flows out of the overflow pipe.

[0036] When the main pipeline pressure increases, the force exerted by water on the diaphragm pressure plate 507 increases until it exceeds the sum of the deadweight of each structure and the pressure generated by the spring 504. At this time, the cover plate 202 will separate from the valve port and release the high-pressure water flow. When the pressure returns to the normal water supply pressure, the cover plate 202 will reset again, and the valve port will no longer flow. This completes an overpressure water and pressure relief, and then resets again, so that the system always maintains a steady-state operation state. When the system pressure changes, the valve port can be controlled by adjusting the spring 504 to control whether there is an overflow. The air inlet and outlet valve 205 provided on the housing 201 assists in the air inlet and outlet of the direct-acting overpressure releaser.

[0037] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
