Description

Technical Field

[0001] This utility model relates to the field of butterfly valve technology, specifically to quick-install butterfly valves. Background Technology

[0002] Butterfly valves are a commonly used fluid control device and are widely used in various industrial and civil fields.

[0003] Quick-release butterfly valves are a type of butterfly valve. They have an opening and closing range of 0-90 degrees and can be fixed at 15-degree intervals. They have low driving torque and are easy and quick to operate. In the fully open state, they have low flow resistance and high flow rate; when partially open, flow rate and pressure can be precisely controlled by adjusting the valve disc angle.

[0004] Most existing quick-install butterfly valves have a fixed-length handle at the top. In some cases, after prolonged periods of inactivity, the rotating block can become jammed. Because the handle is of fixed length, it's difficult to move the rotating block using the handle. Furthermore, the ease with which users with varying strengths can turn the fixed-length handle makes it inconvenient for some. Therefore, developing a quick-install butterfly valve that effectively solves these problems is of significant practical importance. Utility Model Content

[0005] The purpose of this invention is to provide a quick-install butterfly valve, solving the problem that in some butterfly valves, after prolonged periods of inactivity, the rotating block can become jammed. Furthermore, due to the fixed length of the handle, it is difficult to move the rotating block by hand. Additionally, the difficulty of turning the fixed-length handle varies among users of different strength levels, making it inconvenient for some users.

[0006] A quick-install butterfly valve includes a valve unit and an opening / closing unit. The opening / closing unit is located at the top of the valve unit and includes:

[0007] Sleeve;

[0008] A rotating block, which is rotatably connected inside the sleeve;

[0009] A sleeve rod, which is fixedly connected to one side of the rotating block;

[0010] The telescopic rod is slidably connected inside the sleeve, and one end of the telescopic rod is movably inserted into the sleeve;

[0011] A limiting component is provided on the telescopic rod, and the limiting component is used to fix the position of the telescopic rod.

[0022] A limiting block is slidably connected inside the telescopic rod, and the limiting block is fixedly connected to the other end of the spring.

[0023] Preferably, the limiting block is movably engaged with the limiting hole.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] This quick-install butterfly valve allows for easy adjustment of the telescopic rod's extension length by adjusting its position within the sleeve and securing it with a limiting component. This allows for adjustments to the rod's length to suit individuals of varying strengths, making the rotating block easier to turn. Furthermore, if the rotating block becomes jammed, adjusting the telescopic rod length facilitates easier rotation, thus simplifying the opening and closing of the quick-install butterfly valve.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-3 This utility model provides a technical solution:

[0033] Example 1: A quick-install butterfly valve, comprising a valve unit 1 and an opening / closing unit 2, wherein the opening / closing unit 2 is disposed on top of the valve unit 1, and the opening / closing unit 2 includes:

[0034] Sleeve 21;

[0035] Rotating block 22 is rotatably connected inside sleeve 21;

[0036] Sleeve rod 23 is fixedly connected to one side of rotating block 22;

[0037] Telescopic rod 24 is slidably connected inside sleeve rod 23, and one end of telescopic rod 24 is movably inserted into sleeve 21;

[0038] Limiting component 25 is installed on telescopic rod 24 and is used to fix the position of telescopic rod 24.

[0039] Furthermore, valve unit 1 includes:

[0040] Valve body 11;

[0041] The connecting ring seat 12 is provided in two sets, and the two sets of connecting ring seats 12 are respectively fixedly connected to both sides of the valve body 11.

[0042] Valve disc 13 is rotatably connected within valve body 11. Its quick-installation design makes installation and disassembly of the butterfly valve simpler and faster. This reduces maintenance and replacement costs and time, and improves equipment efficiency.

[0043] Furthermore, a valve stem is provided at the top of the valve disc 13, and the valve stem is fixedly connected to the rotating block 22. When the butterfly valve needs to be opened, the rotating block 22 is rotated via the telescopic rod 24 and the sleeve rod 23. Since the rotating block 22 is fixedly connected to the valve disc 13 via the valve stem, the rotation of the rotating block 22 will drive the valve disc 13 to rotate within the valve body 11, thereby opening the butterfly valve. Conversely, when the butterfly valve needs to be closed, the rotating block 22 is rotated in the opposite direction.

[0044] Example 2: A quick-install butterfly valve, comprising a valve unit 1 and an opening / closing unit 2, wherein the opening / closing unit 2 is disposed on top of the valve unit 1, and the opening / closing unit 2 includes:

[0045] Sleeve 21;

[0046] Rotating block 22 is rotatably connected inside sleeve 21;

[0047] Sleeve rod 23 is fixedly connected to one side of rotating block 22;

[0048] Telescopic rod 24 is slidably connected inside sleeve rod 23, and one end of telescopic rod 24 is movably inserted into sleeve 21;

[0049] A limiting component 25 is installed on the telescopic rod 24 and is used to fix the position of the telescopic rod 24. By adjusting the position of the telescopic rod 24 within the sleeve 23 and fixing it with the limiting component 25, the telescopic length of the telescopic rod 24 can be easily adjusted. This allows the length of the telescopic rod 24 to be adjusted according to people with different strengths, making it easier to rotate the rotating block 22. Furthermore, when the rotating block 22 becomes jammed, adjusting the length of the telescopic rod 24 makes it easier to rotate, facilitating the opening and closing of the quick-release butterfly valve.

[0050] Furthermore, the sleeve 21 is fixedly snapped onto the top of the valve body 11.

[0051] Furthermore, a positioning hole 211 is provided on the sleeve 21, which is movably connected to the telescopic rod 24. The movable connection between the positioning hole 211 on the sleeve 21 and the telescopic rod 24 makes the butterfly valve more stable after rotation and opening / closing, further enhancing the connection stability between the opening / closing unit 2 and the valve unit 1.

[0052] Furthermore, the sleeve rod 23 is provided with multiple equidistant limiting holes 231.

[0053] Furthermore, the limiting component 25 includes:

[0054] Spring 251 is installed inside telescopic rod 24, and one end of spring 251 is fixedly connected inside telescopic rod 24;

[0055] Limiting block 252 is slidably connected inside telescopic rod 24, and the limiting block 252 is fixedly connected to the other end of spring 251.

[0056] Furthermore, the limiting block 252 is movably engaged with the limiting hole 231. By adjusting the position of the telescopic rod 24 within the sleeve 23, during the adjustment process, using the spring 251 and the limiting block 252 in the limiting assembly 25, when the telescopic rod 24 moves to the appropriate position, the limiting block 252 will pop out under the action of the spring 251 and engage with the limiting hole 231 on the sleeve 23, thereby fixing the position of the telescopic rod 24.

[0057] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
