[0002] The submerged electromagnetic pulse valve is a valve that can spray gas by energizing it, thereby cleaning the surface of an object. The submerged electromagnetic pulse valve seat is embedded in the air bag and installed, with low resistance, good fluidity, high spray volume, increased load-driven momentum, and expanded the scope of use of gas source pressure. Therefore, the submerged electromagnetic pulse valve is widely used in occasions with a wide range of gas source pressures; the pulse valve includes a pilot valve, a first valve cover, a second valve cover, and a valve body that are connected in sequence. The first valve cover and the second valve cover are both provided with springs, and the connection between the first valve cover and the second valve cover is A first diaphragm assembly is provided, and a second diaphragm assembly is provided at the connection between the second valve cover and the valve body. When the pulse valve is working, the pilot valve is energized to lift the first diaphragm assembly upward, so that the upper end of the first valve cover is in an open state. Thereafter, under the blowing of the air inlet at the bottom of the valve body, the second diaphragm assembly is moved upward, so that the exhaust port of the valve body is connected with the air inlet. According to the above description, the internal space of the second valve cover is in a fixed state, so that the amount of air blown out of the exhaust port remains unchanged. However, when encountering different numbers of objects to be cleaned, the pulse valve cannot adapt to the corresponding working conditions. Utility Model Content

[0013] 1. When the air volume of the exhaust port needs to be adjusted, the driving wheel is rotated first. Under the mutual meshing of the driving wheel and the gear ring, the gear ring rotates. Under the mutual meshing of the gear ring and the three gears, the gears rotate, thereby driving the adjustment sleeve to rotate. Under the threaded cooperation between the adjustment sleeve and the threaded rod, the threaded rod moves downward, causing one end of the sliding rod to move into the second valve cover. When air is blown into the air inlet, the second diaphragm assembly is blown until the second diaphragm assembly abuts against the lower end of the sliding rod, making the distance between the second diaphragm assembly and the exhaust port shorter than that in the prior art, so that the air volume blown out of the exhaust port will be reduced, thereby adapting to different working conditions and improving the use range of the pulse valve.
[0014] 2. When the adjusting sleeve rotates, the cooperation between the limiting ring and the ring groove allows the adjusting sleeve to rotate stably in the second valve cover, preventing the adjusting sleeve from easily popping out of the second valve cover, thereby improving the stability of the adjusting sleeve.

[0018] The present invention will be further described below with reference to the accompanying drawings.
[0019] The embodiment of the present application discloses an improved submerged pulse valve.
[0020] Reference Figure 1 , including a pilot valve 1, a first valve cover 2, a second valve cover 3 and a valve body 4, the pilot valve 1, the first valve cover 2, the second valve cover 3 and the valve body 4 are installed and fixed in sequence from top to bottom, a first diaphragm assembly 5 is clamped and fixed between the pilot valve 1 and the first valve cover 2, a second diaphragm assembly 6 is clamped and fixed between the first valve cover 2 and the second valve cover 3, the first diaphragm assembly 5 includes a first diaphragm and a first fixing frame, the first fixing frame is fixed to the middle of the first diaphragm, the second diaphragm assembly 6 includes a second diaphragm, a first clamping plate and a second clamping plate, the first clamping plate and the second clamping plate are respectively located on the upper and lower sides of the middle of the second diaphragm and are fixed by bolts, a first spring 7 is vertically placed between the pilot valve 1 and the first fixing frame, a second spring 8 is vertically placed between the first valve cover 2 and the first clamping plate, the lower end of the valve body 4 has an exhaust port 9, and an air inlet 10 is formed between the outer peripheral side of the exhaust port 9 and the inner side wall of the valve body 4.
[0021] Reference Figure 2 Three adjustment components 11 are evenly placed around the upper side wall of the second valve cover 3. The adjustment component 11 includes an adjustment sleeve 12 and a push rod 13. The push rod 13 consists of a threaded rod 14 and a sliding rod 15. The cross-section of the sliding rod 15 is square. One end of the sliding rod 15 is integrally arranged at one end of the threaded rod 14. Three rotation grooves 16 are evenly opened around the upper side wall of the second valve cover 3. The second valve cover 3 has a sliding groove 17 at the bottom of the rotation groove 16. The adjustment sleeve 12 is rotatably connected to the rotation groove 16. The lower end of the adjustment sleeve 12 is located in the rotation groove 16, while the upper end of the adjustment sleeve 12 is located outside the second valve cover 3. The threaded rod 14 is threadedly rotated to fit in the adjustment sleeve 12, and the sliding rod 15 is inserted into the sliding groove 17. After the adjustment sleeve 12 rotates, the threaded rod 14 slides in the adjustment sleeve 12 under the mutual threaded cooperation between the adjustment sleeve 12 and the threaded rod 14, thereby driving the sliding rod 15 to slide into the second valve cover 3.
[0022] A limit ring 18 is integrally provided on the outer circumference of the adjustment sleeve 12, and an annular groove 19 is formed on the circumferential sidewall of the rotation groove 16 of the second valve cover 3 for the limit ring 18 to engage and limit. When the adjustment sleeve 12 rotates, the interaction between the limit ring 18 and the annular groove 19 allows the adjustment sleeve 12 to rotate stably within the second valve cover 3, preventing the adjustment sleeve 12 from easily popping out of the second valve cover 3.
[0023] A cushion pad 20 is adhered and fixed to the outer end of the sliding rod 15. When the second diaphragm assembly 6 is moved into the second valve cover 3 by the force of wind in the air inlet 10, the cushion pad 20 prevents the second diaphragm assembly 6 from contacting the lower end of the sliding rod 15.
[0024] The outer end of the adjustment sleeve 12 is sleeved and fixed with a gear 21. The outer circumferences of the three gears 21 are sleeved and meshed with a gear ring 22. The outer side of the gear ring 22 is covered with a protective shell 23. A drive wheel 24 is rotatably connected to the side wall of the protective shell 23, and the drive wheel 24 is meshed with the outer circumference of the gear ring 22. When the drive wheel 24 rotates, the gear ring 22 rotates due to the mutual engagement between the drive wheel 24 and the gear ring 22. The gear ring 22 rotates due to the mutual engagement between the gear ring 22 and the three gears 21, which in turn rotates the gears 21, thereby driving the adjustment sleeve 12 to rotate. Under the threaded engagement between the adjustment sleeve 12 and the threaded rod 14, the threaded rod 14 moves downward, causing one end of the sliding rod 15 to move into the second valve cover 3.
[0025] The above description is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features and principles described in the scope of the present invention patent application are included in the scope of the present invention patent application.
