In addition, when used for a long time after closing, the valve stem may rotate, causing the valve to open accidentally. Therefore, a valve with an easy-to-turn hand wheel is proposed to solve the above-mentioned problems. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a valve that is easy to turn a hand wheel, comprising a valve body, the valve body is internally rotatably connected to a valve stem body, the top of the valve stem body is fixedly connected to a hand wheel body, the hand wheel body is internally slidably connected to a lever, the right side of the lever is fixedly connected to a limiting cylinder, the limiting cylinder is internally slidably connected to a limiting plug rod, the top of the valve body is fixedly connected to a limiting socket, and the limiting plug rod can be plugged into the limiting socket.

[0006] Furthermore, a first magnetic block is fixedly connected to the left side of the interior of the hand wheel body, and the first magnetic block can be magnetically connected to the lever.

[0007] Furthermore, a slider is fixedly connected to the top of the limiting rod, a second magnetic block is fixedly connected to the inner top of the limiting cylinder, and the slider can be magnetically connected to the second magnetic block.

[0008] Furthermore, the outside of the sliding block is slidably connected to the inner wall of the limiting cylinder, and the diameter of the bottom notch of the limiting cylinder is smaller than the diameter of the sliding block.

[0009] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0010] The valve is convenient for turning the hand wheel. When closing the valve, the lever is pulled out of the hand wheel body for a distance, so that it is more convenient to rotate the lever and the hand wheel body. The hand wheel and the valve stem body are rotated by the lever. When the valve is in a closed state, the limit plug rod is located directly above the limit socket. The limit plug rod is pulled down and inserted into the limit socket to maintain the stability of the limit cylinder, the lever, the hand wheel body and the valve stem body, so as to prevent the valve stem body from rotating and causing the valve to open accidentally.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-3 , an embodiment provided by the utility model:

[0018] A valve that is convenient for turning a hand wheel comprises a valve body 1, wherein the valve body 1 is rotatably connected to a valve stem body 2, the top of the valve stem body 2 is fixedly connected to a hand wheel body 3, the inside of the hand wheel body 3 is slidably connected to a lever 4, the right side of the lever 4 is fixedly connected to a limiting cylinder 5, the inside of the limiting cylinder 5 is slidably connected to a limiting plug rod 6, the top of the valve body 1 is fixedly connected to a limiting socket 7, and the limiting plug rod 6 can be plugged into the limiting socket 7.

[0019] Furthermore, the valve stem body 2 can open or close the valve body 1 when it rotates. The valve body 1 plays a role in opening or closing the medium flow path. The handwheel body 3 and the lever 4 facilitate the user to rotate the valve stem body 2 .

[0020] Furthermore, the lever 4 can slide in the hand wheel body 3 , and after the lever 4 is pulled out of the hand wheel body 3 for a certain distance, the hand wheel body 3 can be rotated more labor-savingly and conveniently.

[0021] Furthermore, the limiting cylinder 5 is slidably connected to the limiting rod 6 to maintain the stability of the limiting rod 6. The limiting rod 6 can be plugged into the limiting socket 7 to prevent the limiting cylinder 5, the lever 4 and the handwheel body 3 from rotating.

[0022] Furthermore, the first magnetic block 8 can be magnetically connected to the lever 4 to maintain the stability of the lever 4 in the handwheel body 3, and the second magnetic block 10 can be magnetically connected to the slider 9 to maintain the stability of the slider 9 and the limiting rod 6.

[0023] Furthermore, the diameter of the slider 9 is larger than the bottom opening diameter of the limiting cylinder 5 , thereby preventing the slider 9 and the limiting rod 6 from falling out of the limiting cylinder 5 .

[0024] Working principle: When closing the valve, pull the lever 4 out of the handwheel body 3 for a distance, so that it is more convenient to rotate the lever 4 and the handwheel body 3. The handwheel and the valve stem body 2 are rotated by the lever 4. When the valve is in a closed state, the limit rod 6 is located directly above the limit socket 7. The limit rod 6 is pulled down and inserted into the limit socket 7 to maintain the stability of the limit cylinder 5, the lever 4, the handwheel body 3 and the valve stem body 2, thereby preventing the valve stem body 2 from rotating and causing the valve to open accidentally.

[0025] In summary, the valve with a hand wheel that is easy to turn improves the convenience of turning the hand wheel, can prevent the valve stem from rotating and causing the valve to open accidentally, and solves the problems raised in the above background technology.
