DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with 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, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0024] like Figure 1-3As shown, the embodiment of the present application discloses a regulating valve with an anti-corrosion function, including a valve body 1, an S-shaped partition 2 for separating the water flow on both sides of the valve body 1 is fixed to the inner wall of the valve body 1, a water flow through hole 21 is penetrated through the middle section of the S-shaped partition 2, a lower through hole 11 is arranged at a position corresponding to the water flow through hole 21 on the top of the valve body 1, a mounting block 3 is fixed at a position close to the lower through hole 11 on the top of the valve body 1, and an upper through hole 31 is arranged at a position corresponding to the lower through hole 11 (when the valve body 1 in the present application is in use, the axis of the valve body 1 is horizontal, The mounting block 3 is located at the top of the valve body 1. After the valve core 5 is opened, water flows from the water flow through hole 21 on the S-shaped partition 2 toward the water outlet of the valve body 1 to control the water inlet flow of the valve body 1, and the water is not easy to flow out from the lower through hole 11 and the upper through hole 31). A valve stem 4 passing through the upper through hole 31 and the lower through hole 11 is arranged on the top of the mounting block 3. The lower end of the valve stem 4 is connected to the valve core 5 that cooperates with the water flow through hole 21. The edge of the valve core 5 is wrapped with a sealing rubber sleeve 6. The outer diameter of the sealing rubber sleeve 6 is smaller than the inner diameter of the upper through hole 31 and the inner diameter of the lower through hole 11.

[0025] When the staff closes the valve core 5 through the valve stem 4, the valve core 5 cooperates with the inner wall of the water flow hole 21 and presses the sealing rubber sleeve 6, thereby achieving a good sealing effect. When the sealing rubber sleeve 6 is seriously aged after long-term use, in order to ensure the sealing performance of the regulating valve, the staff only needs to take out the valve core 5 from the lower through hole 11 and the upper through hole 31 through the valve stem 4 to replace the sealing rubber sleeve 6, which solves the defect that the rubber parts used for sealing in the traditional technology are difficult to replace.

[0026] A sleeve 32 is fixed on the top of the mounting block 3, and a mounting cover 7 is connected to the upper flange of the sleeve 32. The valve stem 4 passes through the mounting cover 7 and is threadedly connected to the mounting cover 7. By rotating the valve stem 4, the staff can control the opening size of the valve core 5, thereby controlling the water flow rate of the valve body 1. In addition, by twisting the valve stem 4, the staff can remove the valve core 5 from the lower through hole 11 and the upper through hole 31.

[0027] An annular groove 22 is provided on the inner wall of the water flow hole 21, and an annular convex strip 51 is integrally formed on the side wall of the valve core 5 to cooperate with the annular groove 22. The annular convex strip 51 cooperates with the annular groove 22 to press the corresponding position of the sealing rubber sleeve 6 and the annular convex strip 51, thereby extending the water flow path and further improving the sealing performance between the valve core 5 and the S-shaped partition 2 when the valve core 5 is closed.

[0028] An annular convex edge 52 is integrally formed at the bottom of the valve core 5 near its edge, and a spherical protrusion 53 is fixed at the top of the valve core 5 near its edge. There are multiple spherical protrusions 53 and they are evenly distributed about the axis of the valve stem 4. The annular convex edge 52 has a good anti-slip effect on the bottom of the sealing rubber sleeve 6, and the spherical protrusion 53 has a good anti-slip effect on the top of the sealing rubber sleeve 6, which fully enhances the stability of the sealing rubber sleeve 6 during use.

[0029] To facilitate the staff to install and disassemble the valve core 5, the lower end of the valve stem 4 is threadedly connected to the top of the valve core 5, and a lateral plate 54 is fixed to the top of the valve core 5 near the valve stem 4. The lateral plate 54 is provided with multiple and evenly distributed about the axis of the valve stem 4.

[0030] A sealing rubber ring is provided at the intersection between the S-shaped partition 2 and the inner wall of the valve body 1 (not shown in the figure, the sealing rubber ring is formed by curing the sealant commonly used for sealing in the prior art). The provision of the sealing rubber ring enhances the sealing performance between the S-shaped partition 2 and the inner wall of the valve body 1, thereby enhancing the sealing performance of the regulating valve.

[0031] A hand wheel 41 is fixed to the top of the valve stem 4, and a rubber tube 42 is fixed to the bottom of the hand wheel 41 and is sleeved on the outside of the valve stem 4. The setting of the hand wheel 41 facilitates the staff to control the opening or closing of the valve core 5 through the valve stem 4, and the setting of the rubber tube 42 enables the bottom of the hand wheel 41 to be in flexible contact with the top of the mounting block 3, which plays a good protective role.

[0032] The valve body 1, S-shaped partition 2, valve core 5, valve stem 4, and lateral plate 54 are all provided with an anti-corrosion and anti-rust coating (the anti-corrosion and anti-rust coating is not shown in the figure). The anti-corrosion and anti-rust coating is formed by curing the anti-corrosion and anti-rust paint. The anti-corrosion and anti-rust coating is provided on the surface of the valve body 1, S-shaped partition 2, valve core 5, valve stem 4, and lateral plate 54, so that the regulating valve has good anti-corrosion and anti-rust properties, which is beneficial to extending the service life of the regulating valve.

[0033] The side wall of the sleeve 32 is provided with a plurality of operation ports 321 . When the valve core 5 moves into the interior of the sleeve 32 , the provision of the operation ports 321 facilitates the staff to disassemble and replace the sealing rubber sleeve 6 .

[0034] The operating principle of a regulating valve with an anti-corrosion function in this embodiment is as follows: when the staff closes the valve core 5 through the valve stem 4, the valve core 5 cooperates with the inner wall of the water flow hole 21 and presses the sealing rubber sleeve 6, thereby achieving a good sealing effect. When the sealing rubber sleeve 6 is seriously aged after long-term use, in order to ensure the sealing performance of the regulating valve, the staff only needs to take out the valve core 5 from the lower through hole 11 and the upper through hole 31 through the valve stem 4 to replace the sealing rubber sleeve 6, which solves the defect that the rubber parts used for sealing in the traditional technology are difficult to replace.

[0035] In other embodiments, in order to further avoid the phenomenon that a small amount of water flows out from the lower through hole 11 and the upper through hole 31, the length of the lower section of the S-shaped partition 2 can be smaller than the length of the upper section of the S-shaped partition 2, so that the water flow hole 21 is as close to the bottom of the valve body 1 as possible. In this way, after the valve core 5 is opened, the water flowing out of the water flow hole 21 quickly flows out from the water flow hole 21 toward the water outlet of the valve body 1, thereby preventing the water from flowing out from the lower through hole 11 and the upper through hole 31.

[0036] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
