Description
Technical Field
[0001] The utility model relates to the technical field of safety valves for large flow distributors, in particular to a safety valve for large flow distributors. Background Art
[0002] A flow distributor is a device used to evenly distribute incoming fluid to multiple outlets, while a safety valve is a valve used to protect equipment or systems from dangers such as overpressure or overcurrent. The combination of a flow distributor and a safety valve can ensure that the fluid will not cause damage to the equipment or threaten the safety of personnel due to overpressure or overcurrent during the distribution process. The flow distributor is usually equipped with a regulating valve to control the flow rate, while the safety valve will automatically open and release the pressure when the fluid pressure exceeds the set value according to the set pressure threshold to protect the equipment or system from damage. In this way, when the fluid is distributed to different outlets, the safety valve can monitor the pressure of the entire system to ensure that the system is within the normal working range. Therefore, the combination of a flow distributor and a safety valve can provide more comprehensive protection for the system and ensure that the system operates stably, efficiently and safely. The existing devices have poor flow control effects and poor pressure relief effects when used.
[0003] Therefore, we propose a safety valve device for a large flow distributor in order to solve the above-mentioned problems. Utility Model Content

[0023] When in use, the controller 8 on the surface of the valve body 1 starts the first motor 2 inside the body to drive the transmission belt 3 to rotate, so that the transmission belt 3 drives the rotating shaft to rotate, and at this time the rotating shaft drives the gear 4 to rotate. Since the gear 4 and the rack 5 are meshed, the rack 5 slides over the slide bar 6 and drives the baffle 7 below to move. At this time, after the baffle 7 is opened, the input to the inside begins, and the internal moving block 10 is impacted. At this time, the moving block 10 slides inside the valve body 1 and drives the spring 9 to contract, so that one side of the moving block 10 slides over the scale sensor 11, and the data is transmitted to the detector 12 through the scale sensor 11. After the incoming flow pressure is detected, when the pressure is too high, the second motor 13 is started to drive the turntable 14 to rotate, so that the through hole 15 on the surface of the turntable 14 coincides with the water pipe inside the valve body 1. When the flow pressure is small, the overlapping position of the through hole 15 and the water pipe is reduced to control the flow rate;
[0024] The inside of the valve body 1 is fixedly connected to the second motor 13, and the front end of the second motor 13 is fixedly connected to the turntable 14, and a through hole 15 is arranged on the surface of the turntable 14, and the through hole 15 is arranged in an array about the turntable 14, and the size of the through hole 15 is consistent with the size of the water pipe inside the valve body 1, and a gasket is arranged at the contact position between the turntable 14 and the inside of the valve body 1, and the gasket is made of rubber, a pressure sensor 16 is arranged inside the valve body 1, and the pressure sensor 16 is connected to the alarm 17, and the inside of the valve body 1 is fixedly connected to the push rod 18, and the front end of the push rod 18 is fixedly connected to the moving plate 19, and a pressure relief pipe 20 is arranged in the valve body 1, and the pressure relief pipe 20 is closed.

In order to prevent the valve body 1 from being damaged, the push rod 18 can be activated by the controller 8 to drive the moving plate 19 to move, so that the moving plate 19 opens the pressure relief pipe 20 to relieve pressure to the outside, and the number of opened pressure relief pipes 20 can be controlled according to the pressure, so as to better relieve pressure.
[0025] Working principle: When using a safety valve for a large flow distributor, the controller 8 on the surface of the valve body 1 is used to start the first motor 2 inside the body to drive the transmission belt 3 to rotate, so that the transmission belt 3 drives the rotating shaft to rotate. At this time, the rotating shaft drives the gear 4 to rotate. Since the gear 4 and the rack 5 are meshed, the rack 5 slides over the slide bar 6 and drives the baffle 7 below to move. At this time, the baffle 7 is opened and input begins to the inside. At this time, the internal moving block 10 is impacted. At this time, the moving block 10 slides inside the valve body 1 and drives the spring 9 to contract, so that one side of the moving block 10 slides over the scale sensor 11. The scale sensor 11 transmits data to the detector 12. After detecting the incoming flow pressure, When the pressure is too high, the second motor 13 is started to drive the turntable 14 to rotate, so that the through hole 15 on the surface of the turntable 14 overlaps with the water pipe inside the valve body 1. When the flow pressure is small, the overlap position of the through hole 15 and the water pipe is reduced to control the flow rate. At this time, the pressure of the water flow can be detected by the rear pressure sensor 16. When the pressure is too high, the alarm 17 is started to remind the staff that the pressure inside the valve body 1 is too high. In order to prevent the valve body 1 from being damaged, the push rod 18 can be started by the controller 8 to drive the moving plate 19 to move, so that the moving plate 19 opens the pressure relief pipe 20 to release pressure to the outside. The number of pressure relief pipes 20 opened can be controlled according to the pressure, so that the pressure can be released better. Thus, a series of work is completed.
