An auxiliary ring 3 is arranged above the connection ring 2. One side of the auxiliary ring 3 is threadedly engaged with a fastening bolt 6 and extends to its lower end. The end of the fastening bolt 6 away from the auxiliary ring 3 is threadedly engaged with the connection ring 2. The fastening bolt 6 extends to the lower end of the connection ring 2. Threaded nuts 7 are threadedly engaged on the outer sides of both ends of the fastening bolt 6. The connection ring 2 and the auxiliary ring 3 are located between the two threaded nuts 7. A sealing outer shell 8 is arranged on the outer side of the threaded nut 7. A sealing rubber ring 9 is fixedly connected to the lower end of the sealing outer shell 8. Protective outer shells 11 are arranged on both corresponding sides of the valve body 1, and a regulating bolt 10 is arranged inside the protective outer shell 11.

[0025] As Figures 1-4 shown, by rotating the threaded nuts 7 at its upper and lower ends under the support of a plurality of fastening bolts 6, the effect of fastening the connection ring 2 and the auxiliary ring 3 can be achieved. Then, by rotating the sealing outer shell 8 outside the threaded nut 7 and the sealing rubber ring 9, the sealing rubber ring 9 at the lower end of the sealing outer shell 8 is rotationally pressed against the connection ring 2. Thus, with the cooperation of the sealing outer shell 8 and the sealing rubber ring 9, the effect of rotationally fastening the internal threaded nut 7 and the fastening bolt 6 can be achieved, and the joints between the internal threaded nut 7 and the sealing rubber ring 9, and the joints between the fastening bolt 6 and the connection ring 2 can be sealed, thereby improving the sealing effect at the joints of the device, effectively preventing corrosion at the joints of the device, and by sealing and connecting the two ends of the valve body 1 with the protective outer shell 11, the effect of simultaneously protecting a plurality of internal sealing rings 13 can be achieved, further improving the sealing performance of the device, and thus effectively preventing the corrosion of the outer material to the joints of the device and the inside of the device.

[0026] In this embodiment, as Figure 2 and Figure 3 shown, an auxiliary outer shell 15 is arranged below the auxiliary ring 3. The connection manner of the auxiliary outer shell 15 and the sealing outer shell 8 is the same. The auxiliary outer shell 15 is connected to the auxiliary ring 3 through a sealing rubber ring 9, and the sealing outer shell 8 is connected to the connection ring 2 through a sealing rubber ring 9. The sealing rubber ring 9 is used for sealing.

[0027] The fastening bolt 6 extends to the upper end of the fastening nut 7. One end of the fastening bolt 6 away from the fastening nut 7 is threadedly engaged with the sealing housing 8. Both the fastening nut 7 and the fastening bolt 6 are located inside the sealing housing 8.

[0028] As Figure 2 and Figure 3 shown, by the combined use of the auxiliary housing 15 and the sealing housing 8, and by providing sealing rubber rings 9 at both the contact position between the auxiliary housing 15 and the auxiliary ring 3 and the contact position between the sealing housing 8 and the connecting ring 2, it is possible to ensure that when the sealing housing 8 and the auxiliary housing 15 are rotationally fastened, the sealing rubber rings 9 are squeezed, thereby achieving the sealing support for the sealing housing 8 and the auxiliary housing 15, improving their protective and supporting effects on the connection, and by setting the fastening bolt 6 and the sealing housing 8 in a threaded connection, it is possible to ensure the convenience of rotation and the stability of position when the sealing housing 8 is in sealing support, thus enhancing the stability during its sealing connection.

[0029] In this embodiment, as Figure 2 shown, the connecting ring 2 is snap-connected with a sealing washer 4 through a sealing ring groove 5, and the sealing ring groove 5 is opened on one side of the connecting ring 2.

[0030] As Figure 2 shown, by the support and limitation when the sealing ring groove 5 squeezes the sealing washer 4, the stability of the connection between the connecting ring 2 and the auxiliary ring 3 is ensured, thereby further improving the sealing effect when the device is connected.

[0031] In this embodiment, as Figure 1 and Figure 4 shown, both corresponding ends of the valve body 1 are threadedly engaged with the adjusting bolts 10. One side of the protective housing 11 away from the adjusting bolts 10 is fixedly connected with a rotating connection cylinder 12, and the rotating connection cylinder 12 is threadedly engaged with the valve body 1.

[0032] One side of the protective housing 11 close to the adjusting bolts 10 is fixedly connected with a sealing ring 13, and the sealing ring 13 is used for the sealing of the protective housing 11 and the adjusting bolts 10.

[0033] As Figure 1 and Figure 4 shown, by rotating the rotating connection cylinder 12 outside the valve body 1, the effect of squeezing the protective housing 11 and the sealing ring 13 towards the adjusting bolts 10 is achieved, thereby ensuring the sealing effect when the sealing ring 13 connects the adjusting bolts 10 and the valve body 1, achieving the sealing effect on the connections between the multiple adjusting bolts 10 and the valve body 1 inside, and further enhancing the stability when the device is sealed.

[0034] In this embodiment, as Figure 1As shown, support grooves 14 are provided on two opposite sides of the valve body 1. The support grooves 14 are located between a plurality of adjusting bolts 10, and the adjusting bolts 10 are used for supporting the outer sealing member.

[0035] As Figure 1 shown, by placing the sealing member when connecting with the outer connecting member through the two support grooves 14 provided at both ends of the valve body 1, the sealing effect at the connection between the device and the outer member can be further improved, effectively preventing the outer water flow or other materials from flowing into the device interior for corrosion, thereby improving the corrosion resistance of the device.

[0036] It should be noted that the present utility model is a corrosion-resistant regulating valve. By rotating the fastening nuts 7 at its upper and lower ends under the support of a plurality of fastening bolts 6, the effect of fastening the connecting ring 2 and the auxiliary ring 3 is achieved. Then, by rotating the sealing housing 8 outside the fastening nut 7 and the sealing rubber ring 9, the sealing rubber ring 9 at the lower end of the sealing housing 8 is rotationally pressed against the connecting ring 2. Thus, with the cooperation of the sealing housing 8 and the sealing rubber ring 9, the effect of rotationally fastening the internal fastening nut 7 and the fastening bolt 6 is achieved, and the joints between the internal fastening nut 7 and the sealing rubber ring 9 and between the fastening bolt 6 and the connecting ring 2 can be sealed, thereby improving the sealing effect at the joints of the device, effectively preventing corrosion at the joints of the device, and by sealingly connecting the two ends of the valve body 1 with the protective housing 11, the effect of simultaneously protecting a plurality of closed rings 13 inside is achieved, further improving the sealing performance of the device, and thus effectively preventing the corrosion of the joints of the device and the interior of the device by external materials.
