Technical Field

[0001] The utility model relates to the field of control valves, in particular to a water supply and drainage control valve. Background Art

[0002] Water supply and drainage control valves are devices used to control the flow of water or other fluids in piping systems. They are widely used in many fields such as construction, industrial facilities, urban water supply systems and sewage treatment systems. The main functions of water supply and drainage control valves include opening or closing water flow, adjusting flow rate, preventing backflow, and automatic operation under specific conditions. When the control valve is opened quickly, due to the sudden acceleration of the water flow speed, a strong water flow impact will be generated. This impact may cause damage to the mechanical components inside the control valve, thereby affecting the service life of the equipment and being more inconvenient.

[0003] Therefore, it is necessary to design a water supply and drainage control valve that can buffer the water when the flow control valve is opened, avoid excessive water flow impact that may cause damage to the flow control valve, and extend the service life of the equipment. Utility Model Content

[0005] The technical solution is: a water supply and drainage control valve, including a valve body, a first connecting flange, a second connecting flange, fixing bolts, a mounting frame, an adjusting assembly and a buffer assembly. The first connecting flange is connected to the left and right sides of the valve body, and the upper part of the valve body is detachably connected to the second connecting flange through multiple fixing bolts. The upper middle part of the second connecting flange is connected to the mounting frame. The mounting frame is provided with an adjusting assembly that can accurately control the water flow, and the adjusting assembly is provided with a buffer assembly that can buffer the water.

[0006] Furthermore, the regulating assembly includes a flow control valve, a screw, a slider, a rotating block, a worm gear and a worm. The upper part of the mounting frame is rotatably connected to the rotating block, the rotating block is threadedly connected to the screw, the lower side of the screw is connected to the flow control valve, the flow control valve is located inside the valve body, the left and right sides of the flow control valve are connected to sliders, the sliders are slidably connected to the mounting frame, the outside of the rotating block is connected to a worm gear, the upper left part of the mounting frame is rotatably connected to the worm, and the worm and worm gear are engaged with each other.

[0007] Furthermore, a buffer assembly is included, which includes a buffer block and a telescopic spring. The buffer block is slidably connected to the lower part of the flow control valve, and a telescopic spring is connected between the buffer block and the flow control valve.

[0008] Furthermore, it also includes a rotating handle, and the front side of the worm is connected to the rotating handle.

The indicator block is connected to the right side of the upper part of the screw rod, and the scale is connected to the upper side of the right part of the installation frame. The scale is slidably connected to the indicator block.

[0011] The beneficial effects are as follows: 1. When water flows into the valve body, the utility model contacts the buffer block, and the buffer block is driven upward by the impact of the water flow. The telescopic spring is squeezed and then recovers, so that the buffer block moves and resets, thereby achieving the effect of buffering the water when the flow control valve is opened, avoiding damage to the flow control valve due to excessive water flow impact, and extending the service life of the equipment.

[0012] 2. The utility model drives the rotating block to rotate by meshing the worm and the worm wheel, so that the screw moves upward, drives the flow control valve to move upward, and drives the indicating block to move upward on the scale. The flow control valve can be controlled to open by the worm and worm wheel transmission, and the indicating block can be accurately controlled by observing the moving distance of the indicating block on the scale, thereby improving the accuracy of water flow regulation.

The valve 6 is located inside the valve body 1, and sliders 8 are connected to the left and right sides of the flow control valve 6. The sliders 8 are slidingly connected to the mounting frame 5. The lower part of the flow control valve 6 is slidingly connected to a buffer block 9, and a telescopic spring 10 is connected between the buffer block 9 and the flow control valve 6. A worm gear 12 is connected to the outside of the rotating block 11, and a worm 13 is rotatably connected to the upper left part of the mounting frame 5.
