[0002] As a common landscape facility, fountains are widely used in public places such as city squares, parks, and commercial centers. The effect of the fountain mainly depends on the height, shape, and change of the water flow, and the height of the water flow is directly affected by the pump pressure. How to effectively regulate the water spraying pressure of the pump has become one of the key issues in fountain design and construction. Some existing pressure regulation devices are usually connected in series to the fountain pump outlet pipe through flanges. For the fountain pump outlet pipe with a relatively large diameter, the weight of the supporting pressure regulation device is also relatively heavy. When installing, it is necessary to lift the pressure regulation device and align the holes on the two flange plates, which is difficult and consumes a large amount of physical strength. Then, bolts are inserted. During this process, if the holes on the two flange plates are offset, it will be difficult for the bolts to pass through the two flange plates, and the whole process is quite laborious.

[0024] In this embodiment, when installing the valve body 101, first place the cushion block 109 on the pipe orifice to be installed, and rotate the adjusting bolt 107 to make the cushion block 109 press against the pipe orifice to be installed, thereby finely adjusting the position of the connecting flange 104. After adjustment, fix the connecting flange 104 at the pipe orifice to be installed through the connecting bolt 105, and the water flow adjustment structure adjusts the water pressure.

[0025] In one embodiment, as Figure 2 shown, the water flow adjustment structure includes a rotating block 201 rotatably arranged inside the valve body 101. A water passing hole 208 penetrates through the rotating block 201, and the position of the water passing hole 208 corresponds to that of the water inlet 102. The upper surface of the rotating block 201 contacts and supports the lower end of a support sleeve 205. The outer diameter of the support sleeve 205 is smaller than the inner diameter of the valve body 101. A sealing ring 206 that matches the gap between the support sleeve 205 and the valve body 101 is provided on the outside of the support sleeve 205. A first sealing cover 202 is threadedly connected above the rotating block 201 inside the valve body 101. The upper end of the support sleeve 205 is connected to the lower surface of the first sealing cover 202. A connecting column 203 is connected to the center of the upper surface of the rotating block 201.

[0027] In one embodiment, as Figure 2 shown, the water pressure monitoring unit includes a pressure detector 403 arranged on the outer wall at the water outlet 103. The detection port of the pressure detector 403 is communicated with the inside of the water outlet 103. The pressure detector 403 measures the water pressure at the water outlet 103 in real time and transmits the data to the main control room of the fountain, facilitating the operator to adjust the water spraying pressure of the fountain pump through the driving structure.

[0028] In one embodiment, as Figure 2 、 Figure 3 and Figure 4 shown, the filtering unit includes a plug-in slot 301 arranged at the bottom of the rotating block 201. A filter net 302 is inserted into the plug-in slot 301. The filter net 302 covers the water passing hole 208. A scraping plate 303 is provided at the upper end of the filter net 302, and a sealing plate 305 is provided at the lower end of the filter net 302. Both the scraping plate 303 and the sealing plate 305 match the size of the bottom surface of the plug-in slot 301. A reinforcing plate 304 is provided on the filter net 302. A pressing spring 306 is connected to the lower surface of the sealing plate 305, and a sliding piece 307 is connected to the lower end of the pressing spring 306. The bottom of the valve body 101 is threadedly connected with a third sealing cover 308. The third sealing cover 308 presses the filter net 302 into the plug-in slot 301 through the pressing spring 306. The filter net 302 filters the water flowing through the water passing hole 208. When the filter net 302 is cleaned regularly, first unscrew the third sealing cover 308, and then take out the filter net 302. The scraping plate 303 on the filter net 302 simultaneously scrapes the dirt remaining in the plug-in slot 301. The reinforcing plate 304 improves the structural strength of the filter net 302 and inhibits the deformation of the filter net 302. The sealing plate 305 seals the opening of the plug-in slot 301.

[0029] In one embodiment, as Figure 2 shown, a second sealing cover 207 is provided at the top of the valve body 101 to protect the worm gear 204 and the worm 402 from dust and water, and improve the service life of the equipment.

[0030] In one embodiment, as Figure 1 shown, the cushion block 109 is made of nylon.

After the adjustment is in place, connect the connecting flange 104 to the flange at the pipe orifice to be installed through the connecting bolt 105 to complete the installation. The pressure detector 403 measures the water pressure at the water outlet 103 in real time and transmits the data to the main control room of the fountain. The operator controls the driving motor 404 to rotate. The driving motor 404 drives the worm 402 to rotate. The worm 402 drives the worm gear 204 to rotate. The worm gear 204 drives the connecting column 203 to rotate. The connecting column 203 drives the rotating block 201 to rotate, so that the water passing hole 208 deviates from the water inlet 102, and the resistance of the water flowing from the water inlet 102 into the valve body 101 increases, and the water pressure at the water outlet 103 decreases, realizing the on-demand adjustment of the water pressure at the water outlet 103. The third sealing cover 308 presses the filter screen 302 in the insertion slot 301 through the compression spring 306. The filter screen 302 filters the water flowing through the water passing hole 208. When cleaning the filter screen 302 regularly, first unscrew the third sealing cover 308, and then take out the filter screen 302. The scraping plate 303 on the filter screen 302 simultaneously scrapes the dirt remaining in the insertion slot 301.
