Description

Technical Field

[0001] The present application relates to the field of valve technology, and in particular to a wear-resistant valve component. Background Art

[0002] A valve is a mechanical device used to control the flow of fluid. It usually consists of one or more movable discs and a valve body. The main function of a valve is to allow fluid to pass when needed, or to prevent fluid flow when not needed, thereby achieving fluid control, regulation and cut-off.

[0003] The valve disc in the valve will be washed by the water flow during long-term use, causing wear and scratches on the surface of the valve disc. Especially in the case of high-speed fluid, the scouring effect is more obvious. This scouring effect will cause the surface of the valve disc to gradually lose its smoothness, increase friction and wear, and reduce its wear resistance. Utility Model Content

[0006] Preferably, the wear-resistant protection mechanism includes a guide rod fixedly connected to the outer surface of the valve disc, and a lower fixed plate is provided at the bottom of the valve disc. The upper fixed plate and the lower fixed plate can be simply and quickly assembled to the valve disc through the wear-resistant protection mechanism, making it more impact-resistant and wear-resistant.

[0007] Preferably, an upper fixed plate is movably mounted on the top of the lower fixed plate, and the outer surfaces of the lower fixed plate and the upper fixed plate are both provided with adapting grooves, and the adapting grooves and the guide rods can be just snapped together.

[0008] Preferably, a fixing plate is fixedly connected to the outer surface of the lower fixing plate, a rotating shaft is fixedly penetrated through the inner side of the fixing plate, and a plurality of groups of recessed grooves are provided at the edges of the lower fixing plate and the upper fixing plate to facilitate the embedding of the screw.

[0009] Preferably, the outer surface of the rotating shaft is rotatably connected with a screw rod, and the outer surface of the screw rod is threadedly sleeved with a butterfly nut.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. The wear-resistant valve assembly uses a wear-resistant protection mechanism to stably install the upper and lower sets of fixed plates on the periphery of the valve disc, effectively protecting the valve disc surface from the influence of long-term erosion by water flow, reducing the wear and scratches on the valve disc surface, and improving the wear resistance and service life of the valve disc.

[0012] 2. The wear-resistant valve assembly has two sets of upper and lower fixed plates, which ensure the stability of the valve disc through precise engagement and firm installation, preventing it from shaking or loosening under the impact of water flow, thereby ensuring the normal operation of the valve.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] See also Figure 1-6A wear-resistant valve assembly comprises a valve 1, a valve seat 2 is arranged inside the valve 1, a water control platform 3 is fixedly connected to the top of the valve seat 2, a water outlet 4 is arranged at the bottom of the water control platform 3, a rotating rod 5 is threadedly sleeved on the inner surface of the water control platform 3, a knob 6 is arranged on the top of the rotating rod 5, a plug 7 is arranged at the bottom of the rotating rod 5, a valve disc 8 is arranged on the outer surface of the rotating rod 5, and a wear-resistant protective mechanism is arranged on the outer surface of the valve disc 8.

[0022] Through the above technical solution, when the valve 1 is in use, the rotary rod 5 can be moved up and down by turning the knob 6, so that the plug 7 can block or open the water outlet 4, and cooperate with the valve flap 8 to control the size of the water flow, so that the water flows out through the outer opening of the water control platform 3. In the process of the water flow flushing back and forth, in order to improve the strength and wear resistance of the valve flap 8, a wear-resistant protection mechanism is designed.

[0023] Specifically, the wear-resistant protection mechanism includes a guide rod 9 fixedly connected to the outer surface of the valve disc 8 , and a lower fixed plate 10 is arranged at the bottom of the valve disc 8 .

[0024] Through the above technical solution, five groups of guide rods 9 are provided, which are respectively matched with five matching grooves 12.

[0025] Specifically, an upper fixing plate 11 is movably mounted on the top of the lower fixing plate 10 , and outer surfaces of the lower fixing plate 10 and the upper fixing plate 11 are both provided with adapting grooves 12 .

[0026] Through the above technical solution, the upper fixing plate 11 and the lower fixing plate 10 are provided with matching adapting grooves 12 which can just clamp the guide rod 9 and achieve the effect of precise positioning.

[0027] Specifically, a fixing plate 13 is fixedly connected to the outer surface of the lower fixing plate 10 , and a rotating shaft 14 is fixedly penetrated through the inner side of the fixing plate 13 .

[0028] Through the above technical solution, when the screw 15 rotates along the rotating shaft 14 , its surface can just fit into the grooves opened at the edges of the upper fixing plate 11 and the lower fixing plate 10 .

[0029] Specifically, a screw rod 15 is rotatably connected to the outer surface of the rotating shaft 14 , and a butterfly nut 16 is threadedly sleeved on the outer surface of the screw rod 15 .

[0030] Through the above technical solution, the butterfly nut 16 can stably limit the screw rod 15 after the position is adjusted, so that the upper and lower sets of fixing plates can be stably installed on the outer periphery of the valve disc 8.

[0031] Working principle: When the valve 1 is in use, the rotary rod 5 can be moved up and down by turning the knob 6, thereby driving the plug 7 to block or open the water outlet 4 to allow water to flow out, and the valve flap 8 can control the size of the water flow, allowing the water to pass through the outer opening of the water control platform 3 at different flow rates. Considering that in the process of water flowing through the inside of the water control platform 3, the water flow will flush the valve flap 8 for a long time, which will easily cause the surface of the valve flap 8 to gradually lose its smoothness, increase surface wear, and reduce wear resistance. In view of this, a wear-resistant protection mechanism is designed, by respectively clamping the upper solid plate 11 and the lower solid plate 10 on the upper and lower parts of the valve flap 8, By cooperating with the matching grooves 12 on the surfaces of the two sets of solid plates and accurately engaging the corresponding guide rods 9, the upper solid plate 11 and the lower solid plate 10 can be placed in the accurate installation position. Then, the screw 15 is rotated along the rotating shaft 14 to allow each screw 15 to be embedded in the corresponding grooves at the edges of the upper and lower sets of solid plates. Finally, the butterfly nut 16 is screwed down along the surface of the screw 15 until the butterfly nut 16 is tightly against the upper surface of the upper solid plate 11. The upper and lower sets of solid plates can be stably and quickly installed on the outer periphery of the valve disc 8, effectively protecting the surface of the valve disc 8 from the influence of long-term erosion by water flow, reducing the wear and scratches on the surface of the valve disc 8, and improving the wear resistance and service life of the valve disc 8.
