DETAILED DESCRIPTION

[0022] 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 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.

[0023] See also Figure 1-6The utility model provides a technical solution: a pressure reducing electromagnetic valve device, including a valve body 1 and a valve 2, and also including a fixing ring 3, wherein the inner wall of the connecting pipe on both sides of the valve 2 in the valve body 1 is fixedly provided with a mounting ring 15, each of the mounting rings 15 is symmetrically penetrated with a slot 16, and the end face of the fixing ring 3 is fixedly provided with an insert block 13 for inserting into the slot 16 to fix the fixing ring 3, and the inner wall of the fixing ring 3 is fixedly provided with a buffer frame 4, and the side wall of the buffer frame 4 is penetrated with a drainage groove 5 and a plurality of drainage grooves are evenly arranged along the outer wall of the buffer frame 4, and a buffer plate 6 is slidably arranged in the buffer frame 4, and a buffer spring 7 fixedly connected to the bottom of the buffer frame 4 is fixedly provided at one end of the buffer plate 6 close to the bottom of the buffer frame 4, and the buffer spring 7 is evenly arranged along the end face of the buffer plate 6, and a front water hole 11 and a rear water hole 12 are respectively penetrated on the end face of the buffer plate 6 and the bottom of the buffer frame 4.

[0024] Specifically, a stabilizing shaft 8 is fixedly provided at the bottom of the buffer frame 4, and a through groove 9 is opened on the buffer plate 6 for the stabilizing shaft 8 to pass through and is slidably connected to the stabilizing shaft 8. The buffer spring 7 is sleeved on the stabilizing shaft 8. Through the cooperation between the stabilizing shaft 8 and the through groove 9, it is ensured that the buffer plate 6 can slide stably in the buffer frame 4 under the impact of water flow without shaking, thereby reducing the generation of noise.

[0025] Specifically, the end of the buffer disk 6 away from the valve 2 is a conical surface, which can reduce the instantaneous force on the buffer disk 6. A plurality of front water holes 11 are opened along the surface of the buffer disk 6 to further reduce the force on the buffer disk 6 and allow a portion of the water to flow into the buffer frame 4 from the front water holes 11.

[0026] Specifically, a plurality of buffer rubber pads 10 are fixedly provided on the inner wall at the bottom of the buffer frame 4. Before the buffer spring 7 is compressed to the limit, the buffer disk 6 contacts the buffer rubber pad 10 for buffering, thereby ensuring the flexible buffering of the buffer disk 6, reducing the probability of damage to the buffer disk 6, and avoiding the noise generated by the buffer spring 7 being compressed to the limit.

[0027] Specifically, the outer wall of the fixing ring 3 is in contact with the inner wall of the connecting pipe of the valve body 1, and the side wall of the insert block 13 is symmetrically provided with a block groove 17, in which a block spring 18 is fixedly provided, and the block spring 18 is fixedly connected with a block 14 which is abutted against the side wall of the mounting ring 15 for limiting the fixing ring 3. Through the elastic force of the block spring 18, the block 18 slides out of the block groove 17 and is in contact with the mounting ring 15, thereby limiting the fixing ring 3.

[0028] Specifically, one side of the block 14 outside the block groove 17 is an inclined surface and is inclined toward the bottom direction of the buffer frame 4, which is convenient for the installation of the fixing ring 3. When installing the fixing ring 3, the plug block 13 is inserted along the slot 16, and the inclined surface of the block 14 is subjected to force to make the block 14 compress the block spring 18 and slide into the block groove 17 until the fixing ring 3 is in contact with the mounting ring 15. At this time, the block groove 17 just slides out of the slot 16. Under the elastic force of the block spring 18, the block 14 slides out of the block groove 17 and is in contact with the end face of the mounting ring 15, thereby limiting the plug block 13 and completing the installation of the fixing ring 3. The inner wall of the block groove 17 is symmetrically provided with a limiting groove 19, and the side wall of the block 14 located in the block groove 17 is fixedly connected with a limiting block 20 slidably connected to the limiting groove 19. The limiting of the limiting groove 19 and the limiting block 20 can prevent the block 14 from sliding out of the block groove 17 too much and affecting the installation of the fixing ring 3.

[0029] A specific application example of this embodiment is:

[0030] When the device is in use, when water rushes out after the valve 2 is opened, the water flow first contacts the buffer plate 6, and the buffer plate 6 is compressed by the buffer spring 7 to buffer the impact force. A part of the water flow flows into the buffer frame 4 through the front water hole 11 on the buffer plate 6, and most of the water flow enters the buffer frame 4 through the movement of the buffer plate 6. The water in the buffer frame 4 is discharged through the drainage groove 5 and the rear water hole 12, so that the water flow is buffered, so that the water flow will not directly impact the gate and cause the gate to vibrate and make noise. After a period of use, if the buffer frame 4 is damaged, the buffer frame 4 can be disassembled and replaced, and the buffer plate 6 is pressed to slide the buffer plate 6 into the annular groove frame 4. The gap in the drainage groove 5 presses the block 14 into the block groove 17. The plug block 13 loses the limit of the block 14 and can slide out of the slot 16. The fixing ring 3 is disassembled to replace the entire buffer frame 4 structure. During installation, the plug block 13 is inserted along the slot 16. The inclined surface of the block 14 is subjected to force to make the block 14 compress the block spring 18 and slide into the block groove 17 until the fixing ring 3 and the mounting ring 15 are in contact. At this time, the block groove 17 just slides out of the slot 16. Under the elastic force of the block spring 18, the block 14 slides out of the block groove 17 and contacts the end face of the mounting ring 15, thereby limiting the plug block 13 and completing the installation of the fixing ring 3.
