DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figure 1 - Figure 2As shown in the figure, an integrated high-frequency generator with adjustable frequency and intensity includes a valve body 101, a high-frequency generating mechanism and an intensity adjusting mechanism respectively arranged in the valve body 101. A valve rod 114 and a flow channel are arranged in the valve body 101. A valve plate 103 for opening and closing the flow channel is arranged at the end of the valve rod 114 corresponding to the middle of the flow channel. The high-frequency generating mechanism includes a first driving mechanism, which drives and connects the valve rod 114 and controls the opening and closing of the flow channel through the valve plate 103. The intensity adjusting mechanism includes a second driving mechanism and an intensity adjusting member. The second driving mechanism drives and connects the upper part of the valve rod 114 and is used to adjust the intensity adjusting member by driving the circumferential rotation of the valve rod 114. The intensity adjusting member is correspondingly arranged in the flow channel and on the valve plate 103.

[0024] In reality, a liquid inlet 117 and a liquid outlet 102 are respectively arranged on the valve body 101 corresponding to the flow channel, and are respectively connected to the cleaning pipeline through the liquid inlet 117 and the liquid outlet 102. During use, the first driving mechanism of the high-frequency generating mechanism drives the valve rod 114 to move up and down, so that the valve plate 103 on the valve rod 114 opens and closes the flow channel. By controlling the driving frequency of the first driving mechanism, the opening and closing control of the flow channel by the valve plate 103 at the target frequency can be realized, so that the cleaning medium flowing in the target cleaning equipment such as a shell-and-tube heat exchanger forms a high-frequency oscillation wave. The second driving mechanism of the intensity adjusting mechanism drives the valve rod 114 to rotate circumferentially, so as to adjust the relative position of the intensity adjusting member on the valve plate 103 and the intensity adjusting member in the flow channel, and further realize the adjustment of the intensity of the high-frequency oscillation wave formed by the cleaning medium.

[0025] Specifically, the first driving mechanism includes a piston cavity, a piston 113 and a first spring 112. The piston 113 is arranged in the middle of the valve rod 114 and the piston 113 is movably arranged in the piston cavity. The first spring 112 is arranged between the piston 113 and the top wall of the inner cavity of the piston cavity. An air cavity is formed between the bottom of the piston 113 and the bottom of the piston cavity. An air inlet 118 and an air outlet 119 are respectively arranged on the cavity wall of the piston cavity corresponding to the air cavity. The air inlet 118 is used to connect an air inlet valve, an air pump and an air source, etc. The air outlet 119 is used to communicate with the outside air through a valve. After the air inlet valve is opened and the exhaust valve is closed, and the air inlet 118 intakes air, under the action of air pressure, the valve rod 114 is pushed up by the piston 113. At this time, the first spring 112 is compressed, so that the valve plate 103 opens the flow channel. After the air inlet valve is closed and the exhaust valve is opened, under the elastic force of the first spring 112, the valve rod 114 and the valve plate 103 are pushed to quickly fall, and then the flow channel is closed by the valve plate 103. By controlling the air inlet and exhaust valves and the air pump, the valve plate 103 can realize the opening and closing control of the flow channel at a high frequency (10 times / s). In reality, the specifications of the first spring 112 are selected according to the specifications of the high-frequency generator. Different specifications of high-frequency generators use different types of target cleaning equipment or corresponding cut-off water pressures, etc.

[0026] In reality, the strokes of the valve stem 114 and the valve plate 103 are set according to the size of the flow channel, etc. A limiting protrusion 108 is provided on the inner side wall of the piston cavity corresponding to the piston 113 to prevent the valve stem 114 and the valve plate 103 from having excessive strokes and causing collisions and damages between the valve plate 103 and the side wall of the flow channel.

[0027] Preferably, a sealing cavity is provided between the piston cavity and the flow channel. A sealing rubber ring 104 is coaxially arranged with the valve stem 114 on the side wall of the sealing cavity. A second spring 105 is provided between the top of the sealing rubber ring 104 and the inner top wall of the sealing cavity. The valve stem 114 is inserted into the sealing rubber ring 104, and the sealing rubber ring 104 is arranged in a fitting manner with the valve stem 114. The second spring 105 is in a compressed state. Through the extrusion action of the second spring 105 on the sealing rubber ring 104, the sealing rubber ring 104 undergoes a certain deformation, so as to seal the gap between the valve stem 114 and the flow channel and prevent the cleaning medium in the flow channel from leaking. In practice, a plurality of limiting columns 121 are arranged in an annular array on the top wall of the sealing cavity. An extrusion ring 122 is placed on the top of the sealing rubber ring 104. A plurality of the second springs 105 are vertically arranged on the top of the extrusion ring. The second springs 105 are respectively sleeved outside the limiting columns 121. Thus, through the uniformly distributed plurality of second springs 105 and an extrusion ring 122, an equal spring elastic extrusion force is applied to the sealing rubber ring 104, and further the sealing rubber ring 104 undergoes a certain deformation. The plurality of limiting columns 121 not only prevent the second spring 105 from bending and affecting the valve stem, but also the cooperation with the plurality of second springs 105 also prevents the extrusion ring 122 from being misaligned relative to the valve stem and causing friction with the valve stem, etc.

[0028] In practice, a communication hole is provided at the top of the sealing cavity. The valve stem 114 is inserted into the communication hole, the sealing cavity and the flow channel; multi-stage sealing rubber rings 106 are provided on the side wall of the communication hole to further form multi-stage sealing of the gaps between the valve stem 114 and the flow channel and between the sealing cavity and the air cavity to ensure the sealing effect. In addition, sealing rubber rings 107 are also provided on the side wall of the piston 113 to improve the sealing performance of the air cavity.

[0029] The second driving mechanism includes a servo motor 109, a first bevel gear 110 and a second bevel gear 111. The rotating shaft of the servo motor 109 is horizontally arranged and is drivingly connected to the first bevel gear 110. The second bevel gear 111 is rotatably arranged on the outer top of the piston cavity. The first bevel gear 110 is meshed and connected with the second bevel gear 111; a gear through hole is provided in the middle of the second bevel gear 111. A key groove is vertically provided on the hole side wall of the gear through hole. A limiting key 120 is axially arranged on the side wall of the valve stem 114 corresponding to the key groove, as Figure 5As shown, the valve stem 114 movably passes through the gear through-hole. The servo motor 109 is fixed on the valve body 101, and the rotating shaft of the servo motor 109 is drivingly connected with a first bevel gear 110. A second bevel gear 111 is rotatably arranged at the top of the piston chamber and meshed with the first bevel gear 110. There is a through-hole at the top of the piston chamber, and its size is set corresponding to the size of the valve stem 114 and the limit key 120 thereon; a through-hole is correspondingly arranged in the middle of the second bevel gear 111, and the valve stem 114 passes out of the piston chamber and passes through the gear through-hole of the second bevel gear 111, and the limit key 120 on the valve stem 114 is in the keyway. Therefore, when the second bevel gear 111 rotates, the valve stem 114 and the valve plate 103 are driven to rotate through the action of the keyway and the limit key 120. In reality, the length of the limit key 120 is at least greater than the stroke of the valve stem 114, so that when the valve stem 114 moves up and down, the limit key 120 is always in the keyway, avoiding the circumferential misalignment of the valve stem 114, the valve plate 103, etc. when the valve stem 114 moves up and down.

[0030] In this embodiment, as Figure 3 and Figure 4 shown, the intensity adjusting member includes a first adjusting hole 115 and a second adjusting hole 116. A plurality of first adjusting holes 115 are evenly distributed on the valve plate 103, and a plurality of second adjusting holes 116 are correspondingly arranged in the flow channel for the first adjusting holes 115. In this embodiment, the flow channel is approximately Z-shaped, and a plurality of second adjusting holes 116 are opened on the side wall in the middle of the flow channel. When the first adjusting hole 115 and the second adjusting hole 116 are completely aligned, when the valve plate 103 is closed, there is still part of the cleaning medium flowing out through the first adjusting hole 115 and the second adjusting hole 116, and the intensity is the smallest at this time; when the first adjusting hole 115 and the second adjusting hole 116 are completely misaligned, the cleaning medium is completely cut off when the valve plate 103 is closed, and the intensity is the largest at this time.

[0031] A high-frequency generating system includes a controller, an air pump, a solenoid valve and a high-frequency generator. The controller is respectively controlling and connecting the air pump and the solenoid valve, and is used to control the start and stop of the air pump and the solenoid valve, etc. The solenoid valve itself has an air inlet passage and an air exhaust passage.
