DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0023] As shown in the drawings, Figures 1-4 A submerged pulse valve, comprising a valve body 1, a pilot exhaust port 11 and a cleaning mechanism 3 installed in the pilot exhaust port 11, the cleaning mechanism 3 comprising a connecting barrel 21, one end of the connecting barrel 21 being inserted into the pilot exhaust port 11, a flow guide barrel 31 being installed in the connecting barrel 21, the flow guide barrel 31 having an open cavity therein, the cavity comprising an air inlet cavity 311, a tapered cavity 312 and a sliding cavity 313, the tapered cavity 312 having a larger diameter at one end close to the air inlet cavity 311 than at the other end close to the sliding cavity 313, a sliding rod 32 being slidingly fitted in the sliding cavity 313, the sliding rod 32 comprising a first end and a second end, the first end being provided with a dome plate 33 slidingly fitted in the flow guide barrel 31, the dome plate 33 being open towards the air inlet cavity 311, the dome plate 33 being able to better receive airflow, the dome plate 33 and the sliding rod 32 being moved by the airflow, one end of the sliding rod 32 penetrating through the flow guide barrel 31, the sliding rod 32 being provided with a limiting block 322 around the circumference, the second end of the sliding rod 32 being detachably connected with a connecting plate 38, a cleaning barrel being provided between the limiting block 322 and the connecting plate 38, the cleaning barrel being able to be detached by detaching the connecting plate 38, so that the cleaning barrel can be replaced when it is dirty, thereby making the cleaning more efficient and convenient.
[0024] Since the diameter of the conical cavity 312 close to one end of the air inlet cavity 311 is larger than the diameter close to one end of the sliding cavity 313, the airflow velocity can be increased, thereby pushing the dome plate 33 and the sliding rod 32 to move away from the valve body 1.
[0025] Further optimization, the flow guide cylinder 31 is installed with a dust screen 37 at one end of the air inlet cavity 311, and the flow guide cylinder 31 is externally provided with a mounting bracket 314 fixedly connected with the connecting cylinder 21.
[0026] The outer periphery of the sliding rod 32 is provided with a limiting plate 321 located in the sliding cavity 313, and the limiting plate 321 is connected with the inner wall of the sliding cavity 313 through a spring 34, which always has a tendency to push the limiting plate 321 to move towards the side close to the conical cavity 312, thereby achieving the function of resetting the sliding rod 32.
[0027] The cleaning cylinder comprises a connecting bracket 35 and a brush cloth 36, the brush cloth 36 is arranged in close contact with the inner wall of the connecting cylinder 21, the brush cloth 36 is arranged on the outer end face of the connecting bracket 35, and the brush cloth 36 and the connecting bracket 35 are detachably connected, the brush cloth 36 and the connecting bracket 35 are connected through magic tape, therefore when the cleaning cylinder is used for a long time, only the brush cloth 36 needs to be replaced, thereby making the use cost lower, and the connection mode of magic tape is more convenient to replace.
[0028] The end of the connecting bracket 35 has a plurality of air holes 351, which can exhaust the airflow in the connecting cylinder 21.
[0029] The end of the sliding rod 32 has a clamping hole 320, and the connecting plate 38 has a clamping buckle 381 matched with the clamping hole 320, so that the disassembly and assembly of the cleaning cylinder is more convenient.
[0030] The outer periphery of the sliding rod 32 is provided with an elastic ring, which is arranged between the connecting plate 38 and the connecting bracket 35, the elastic ring is made of rubber in the application, and the diameter of the elastic ring is smaller than the diameter of the sliding rod 32, so as to stably sleeve the outer periphery of the sliding rod 32, thereby making the connection between the sliding rod 32 and the connecting bracket 35 more firm.
[0031] The outer periphery of the connecting cylinder 21 is provided with a flange 22, the flange 22 and the valve body 1 are fixedly connected through bolts, and the flange 22 and the valve body 1 are pressed with a sealing ring 23.
[0032] The flow guide cylinder 31 is provided with an annular brush 300 for cleaning the sliding rod 32.
[0033] In use: the air flow in the valve body 1 is discharged through the pilot exhaust port 11, the air flow enters into the guide cylinder 31 through the air inlet cavity 311, and then passes through the conical cavity 312, because the diameter of the conical cavity 312 close to the one end of the air inlet cavity 311 is larger than the diameter close to the one end of the sliding cavity 313, so as to increase the air flow velocity, and then push the dome plate 33 and the sliding rod 32 to move away from the valve body 1 in the sliding cavity 313, and then drive the connecting frame 35 to move away from the valve body 1, and then drive the brush cloth 36 to move away from the valve body 1, so that the brush cloth 36 wipes the inner wall of the connecting cylinder 21, thereby playing a role of cleaning the inner wall of the connecting cylinder 21, and when the exhaust is completed, the spring 34 drives the connecting frame 35, the brush cloth 36 and the sliding rod 32 to move close to the valve body 1, and then clean the inner wall of the connecting cylinder 21 again, and the annular brush 300 cleans the outer peripheral wall of the sliding rod 32, thereby preventing the sliding rod 32 from bringing dust into the sliding cavity 313, thereby preventing the subsequent inactivity of the sliding rod 32 due to blockage.
