Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a valve capable of regulating water volume. Background Art

[0002] Valves are control components in fluid conveying systems and come in a wide variety of sizes and types. Valves are typically used as piping accessories to open and close pipelines, control flow direction, and regulate and control the parameters (temperature, pressure, and flow) of the conveying medium. Based on their function, they can be categorized as shutoff valves, check valves, and regulating valves. Valves are control components in fluid conveying systems and have functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion, and overflow and pressure relief.

[0003] It is difficult to determine the amount of water flow when the current valve is used to adjust the water volume. At the same time, it is difficult to determine the amount of water that needs to be adjusted last time when it is reused. Therefore, we propose a valve that can adjust the water volume to solve the above problems. Utility Model Content

[0007] The above-mentioned technical solution is adopted: a first through hole and a second through hole are respectively opened upward through the top of the accommodating groove, a first sealing ring sleeve is fixed in the first through hole, and a second sealing ring sleeve is fixed in the second through hole. The first sealing ring sleeve and the second sealing ring sleeve can effectively prevent water in the valve body from leaking out of the valve body, and the adjusting rod is inserted in the first through hole. The adjusting rod is used to control the opening and closing size of the water hole of the plug, and the connecting rod is inserted in the second through hole. The up and down movement of the plug drives the connecting rod to move up and down, thereby controlling the scale indication of the pointer on the scale, making it convenient to know the opening and closing size of the plug and the water hole, that is, it is convenient to know the size of the water flow.

[0008] Preferably, slide grooves are provided on both sides of the accommodating groove, and sliders are fixed on both sides of the plug, and the sliders are clamped in the slide grooves.

[0009] The above technical solution is adopted: sliding grooves are opened on both sides of the accommodating groove, and sliders are fixed on both sides of the plug. The sliders are clamped in the sliding grooves, and the sliders move up and down in the sliding grooves, so that the plug can move up and down in the accommodating groove.

[0010] Preferably, a threaded hole is formed through the plug, a first sealing ring is sleeved on the adjusting rod, a first thread is formed on the adjusting rod below the first sealing ring, and the plug is threadedly connected to the adjusting rod.

[0011] The above technical solution is adopted: a threaded hole is opened through the plug, a first sealing ring sleeve is provided on the adjusting rod, and a first thread is opened on the adjusting rod below the first sealing ring sleeve. Since the first thread on the adjusting rod is arranged below the first sealing ring sleeve, when the adjusting rod rotates, it can not only ensure the sealing inside the valve body, but also enable the adjusting rod to adjust the plug to move. The plug is threadedly connected to the adjusting rod. When the adjusting rod rotates, the plug moves up and down along the adjusting rod.

[0012] Preferably, a strip-shaped through slot is provided on the shell, and the fixing plate is clamped in the strip-shaped through slot.

[0013] The above technical solution is adopted: a strip-shaped through-slot is opened on the shell, and the fixing plate is clamped in the strip-shaped through-slot. The strip-shaped through-slot enables the fixing plate to extend out of the shell and connect with the pointer, and point to the scale outside the shell for easy reading.

[0014] Preferably, the scale is bonded to the housing.

[0015] By adopting the above technical solution, the scale is bonded to the housing, and when the scale is worn, it is convenient to replace it.
