Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, specifically a straight-nozzle miniature ball valve. Background Technology

[0002] The straight-nozzle miniature ball valve is a miniaturized ball valve mainly used for controlling the switching or regulation of fluids. It is characterized by its compact structure, small size, and light weight, making it suitable for applications with limited space or requiring precise control.

[0003] Currently, the main approach is to first install straight-nozzle miniature ball valves along the horizontal or vertical direction of the pipeline to keep the inlet and outlet axes aligned. Then, the handle can be rotated 90° as needed to open and close the ball valve.

[0004] However, when a straight-nozzle miniature ball valve is used for a long time, the high-frequency rotation during the torque transmission process between the handle and the ball valve stem will aggravate the frictional wear of the seals, resulting in progressive seal failure. The gasket is usually designed with a crimping, which requires special tools to remove, which is time-consuming and laborious. In addition, the bolts between the handle and the ball valve are easily blocked by rust or impurities and are difficult to loosen, which increases the difficulty of disassembly and reduces the efficiency of overall disassembly and replacement. Utility Model Content

[0005] The purpose of this utility model is to provide a straight-nozzle miniature ball valve to solve the problems mentioned in the background art, such as low efficiency in disassembling and replacing worn seals on straight-nozzle miniature ball valves and the time-consuming and laborious disassembly and assembly process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a straight-nozzle miniature ball valve, comprising a ball valve body and a valve stem and a straight handle disposed on the ball valve body; and further comprising;

[0007] An assembly assembly is disposed between a valve stem and a straight handle. The assembly assembly is used to fix the straight handle. The assembly assembly includes an assembly part, which is fixedly installed on the outer wall of the valve stem. A sealing ring is sleeved on the outer wall of the valve stem, and the straight handle is movably inserted into the outer wall of the assembly part.

[0008] A limiting component is disposed between the ball valve body and the straight handle. The limiting component is used to limit the straight handle. The limiting component includes a limiting rod that penetrates the side wall of the ball valve body and is inserted into the side wall of the straight handle.

[0009] Preferably, the top of the ball valve body has a groove, and the sealing ring is engaged inside the groove.

[0010] Preferably, the inner wall of the straight handle has multiple sets of mounting slots, the straight handle is sleeved on the outer wall of the valve stem, and the mounting parts are inserted into the inner wall of the mounting slots.

[0011] Preferably, the top of the valve stem is threaded with a fixing member, which abuts against the top of the straight handle.

[0012] Preferably, the limiting component further includes a movable rod that extends through the top of the ball valve body, and a trapezoidal member is fixedly connected to the bottom of the movable rod, the trapezoidal member being slidably connected inside the ball valve body.

[0013] Preferably, a return spring is sleeved on the outer peripheral wall of the movable rod, and the return spring is fixedly connected between the ball valve body and the trapezoidal component.

[0014] Preferably, the trapezoidal member has a groove on its side wall, and the limiting rod has an inclined block fixedly connected to its side wall, the inclined block being slidably connected inside the groove.

[0015] Preferably, the side wall of the straight handle has a limiting hole, and the limiting rod is inserted into the inner wall of the limiting hole.

[0016] Compared with the prior art, the beneficial effects of this utility model are: by setting an assembly component between the valve stem and the straight handle, the straight handle can be removed by rotating the fixing part upward, and the worn sealing ring can be quickly replaced, thus improving the replacement efficiency of the sealing ring;

[0017] Meanwhile, by setting a limiting component between the ball valve body and the straight handle, and by moving the limiting rod on the limiting component to insert it into the side wall of the straight handle, the straight handle can be limited, avoiding accidental contact with the straight handle and improving the stability of the ball valve body during use.

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0027] like Figure 1 - Figure 6 As shown, this application provides a straight-nozzle miniature ball valve, including a ball valve body 1, a valve stem 2 and a straight handle 3 disposed on the ball valve body 1; and also includes;

[0028] Specifically, such as Figure 3 As shown, an assembly assembly 4 is provided between the valve stem 2 and the straight handle 3. The assembly assembly 4 is used to fix the straight handle 3. The assembly assembly 4 includes an assembly part 402, which is fixedly installed on the outer wall of the valve stem 2. A sealing ring 401 is sleeved on the outer wall of the valve stem 2. The straight handle 3 is movably inserted into the outer wall of the assembly part 402. A fixing part 403 is threadedly connected to the top of the valve stem 2. The fixing part 403 abuts against the top of the straight handle 3. By providing the assembly assembly 4 between the valve stem 2 and the straight handle 3, the straight handle 3 can be removed by rotating the fixing part 403 upward, and the worn sealing ring 401 can be quickly replaced, thus improving the replacement efficiency of the sealing ring 401.

[0029] Specifically, such as Figure 4 As shown, a groove 4011 is provided on the top of the ball valve body 1, and the sealing ring 401 is snapped into the inside of the groove 4011. Multiple sets of assembly grooves 4021 are provided on the inner wall of the straight handle 3. The straight handle 3 is sleeved on the outer wall of the valve stem 2, and the assembly 402 is inserted into the inner wall of the assembly groove 4021. By snapping the sealing ring 401 into the groove 4011 and inserting the straight handle 3 into the outer wall of the assembly 402, the sealing ring 401 can be pressed and fixed.

[0030] Specifically, such as Figure 5 As shown, a limiting component 5 is provided between the ball valve body 1 and the straight handle 3. The limiting component 5 is used to limit the straight handle 3. The limiting component 5 includes a limiting rod 501, which passes through the side wall of the ball valve body 1 and is inserted into the side wall of the straight handle 3. By providing the limiting component 5 between the ball valve body 1 and the straight handle 3, and by moving the limiting rod 501 on the limiting component 5 so that it is inserted into the side wall of the straight handle 3, the straight handle 3 can be limited. This avoids the situation where the straight handle 3 is easily accidentally touched, which would affect the opening and closing of the ball valve body 1, and improves the stability of the ball valve body 1 during use.

[0031] A movable rod 502 passes through the top of the ball valve body 1. A trapezoidal component 503 is fixedly connected to the bottom of the movable rod 502. The trapezoidal component 503 is slidably connected inside the ball valve body 1. A return spring 505 is sleeved on the outer peripheral wall of the movable rod 502. The return spring 505 is fixedly connected between the ball valve body 1 and the trapezoidal component 503. By pressing down on the movable rod 502 and the trapezoidal component 503, the trapezoidal component 503 can drive the limiting rod 501 to slide and retract inside the ball valve body 1, and the straight handle 3 can be rotated to open and close the ball valve body 1. When the movable rod 502 is released, the tension of the return spring 505 can reset the movable rod 502 and the trapezoidal component 503. At the same time, the trapezoidal component 503 can squeeze the limiting rod 501 to slide outward. At this time, the limiting rod 501 will be inserted into the limiting hole 5011 of the straight handle 3 for fixation.

[0032] Specifically, such as Figure 6 As shown, the trapezoidal part 503 has a groove 5041 on its side wall, and the limiting rod 501 has a wedge 504 fixedly connected to its side wall. The wedge 504 is slidably connected inside the groove 5041. The straight handle 3 has a limiting hole 5011 on its side wall, and the limiting rod 501 is inserted into the inner wall of the limiting hole 5011.

[0033] The specific steps of this solution are as follows: First, the sealing ring 401 is snapped into the groove 4011, and the straight handle 3 is inserted into the outer wall of the fitting 402. Then, the fixing part 403 is threaded onto the top of the valve stem 2 to fix the straight handle 3. Next, the ball valve body 1 is installed at the pipe connection for use. Finally, by pressing down the movable rod 502 and the trapezoidal part 503, the trapezoidal part 503 can drive the limiting rod 501 to slide and retract inside the ball valve body 1, and the straight handle 3 can be rotated to open and close the ball valve body 1.
