Description

Technical Field

[0001] This utility model relates to the field of pneumatic clamp valve technology, and in particular to a pneumatic clamp valve that is easy to install and remove. Background Technology

[0002] Pneumatic pinch valves are a new type of valve improved from manual pinch valves to meet special customer requirements. They consist of upper and lower cast iron / cast steel valve bodies, rubber tubing, large and small valve stems, gate, upper and lower guide pillars, and a pneumatic actuator. A drive unit can also be selected as needed. Pneumatic pinch valves are widely used in chemical, petroleum, power, metallurgical, and wastewater treatment industries.

[0003] Existing pneumatic pinch valves require bolting to the pipeline during use. However, during installation, the flanges at both ends of the pinch valve need to be aligned with the flanges of the two pipelines before the bolts and nuts are engaged. This requires one person to hold the pneumatic pinch valve while another person aligns the flanges at both ends of the pneumatic pinch valve with the bolt holes in the pipeline flanges, and then inserts the bolts and nuts for positioning. This is cumbersome and requires multiple people to work, increasing installation costs. Therefore, there is room for improvement. Utility Model Content

[0004] This invention provides a pneumatic clamp valve that is easy to install and remove, in order to solve the problems mentioned in the background art.

[0005] To address the aforementioned issues, this utility model provides a pneumatic clamp valve that is easy to install and remove, comprising a valve body and a positioning mechanism. The valve body has symmetrically arranged positioning flanges at both ends, and the positioning mechanism is symmetrically arranged on both sides of the valve body. The positioning mechanism consists of a fixed ring, a spring telescopic rod, a movable ring, and positioning bolts. The fixed ring is fixedly installed in the valve body. Two spring telescopic rods are symmetrically installed in the fixed ring, with their telescopic ends fixedly connected to the movable ring. The movable ring is slidably connected in the valve body. Several positioning bolts are equidistantly installed on the side of the movable ring away from the spring telescopic rods. The positioning bolts sequentially pass through the positioning flanges in the valve body and the pipe to be installed.

[0006] Preferably, a plurality of limiting strips are symmetrically fixed on both sides of the valve body, and a limiting groove is provided in the movable ring to slide and connect with the limiting strips.

[0007] Preferably, the positioning bolt has a nut threadedly connected to its rear end after passing through the pipe.

[0008] The beneficial effects of adopting the above technical solutions are:

[0009] The design of the movable ring and spring telescopic rod allows the positioning bolt to extend and retract. During installation, the positioning bolt contacts the pipe to be installed. At this time, the positioning bolt is compressed and retracts into the positioning flange of the valve body. Then, by moving the valve body to adjust the position, the positioning bolt is aligned with the positioning hole in the pipe. Once fully aligned, the elastic force of the spring telescopic rod drives the movable ring to move, thereby causing the positioning bolt to pass through the pipe. Finally, the pipe is connected to the valve body by the nut. The installation process eliminates the need to insert the bolts one by one, improving work efficiency. Moreover, one person can complete the installation operation, reducing labor costs. Attached Figure Description

[0014] The embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0015] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, a movable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] like Figure 1-3 In this embodiment, a pneumatic clamp valve that is easy to install and remove includes a valve body 1 and a positioning mechanism 2. The valve body 1 has symmetrically arranged positioning flanges 11 at both ends. The positioning mechanism 2 is symmetrically arranged on both sides of the valve body 1. The positioning mechanism 2 is composed of a fixed ring 21, a spring telescopic rod 22, a movable ring 23, and positioning bolts 24. The fixed ring 21 is fixedly installed in the valve body 1. The spring telescopic rod 22 consists of two symmetrically installed in the fixed ring 21, and the telescopic end is fixedly connected to the movable ring 23. The movable ring 23 is slidably connected in the valve body 1. A number of positioning bolts 24 are equidistantly installed in the movable ring 23 on the side away from the spring telescopic rod 22. The positioning bolts 24 are sequentially inserted into the positioning flanges 11 in the valve body 1 and the pipe 3 to be installed.

[0018] With the above technical solution, when in use, the positioning flange 11 of the valve body 1 abuts against one side of the pipe 3. At this time, the positioning bolt 24 is compressed. Under the action of the movable ring 23 and the spring telescopic rod 22, the positioning bolt 24 has elasticity and then retracts into the positioning flange 11. At this time, by adjusting the position of the valve body 1, the positioning bolt 24 is aligned with the positioning hole in the pipe 3. Then, the spring telescopic rod 22 pushes the movable ring 23 to move the positioning bolt 24, so that the positioning bolt 24 is inserted into the positioning hole of the pipe 3. This eliminates the need to insert bolts one by one, and one worker can complete the work, improving work efficiency and reducing labor costs.

[0019] Preferably, a plurality of limiting strips 25 are symmetrically fixed on both sides of the valve body 1, and a limiting groove 26 is opened in the movable ring 23 to slide and connect with the limiting strips 25.

[0020] Through the above technical solution, the limiting strip 25, in conjunction with the limiting groove 26 in the movable ring 23, is used to ensure that the movable ring 23 can stably drive the positioning bolt 24 to move, thereby ensuring the stability of the positioning bolt 24 insertion.

[0021] Preferably, the positioning bolt 24 passes through the pipe 3 and is threadedly connected to the rear end with a nut 27.

[0022] Through the above technical solution, the nut 27 is used to securely connect the pipe 3 to the valve body 1.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate this utility model and are not intended to limit the technical solutions described in this utility model. Therefore, although this specification has described this utility model in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model, and all technical solutions and improvements that do not depart from the spirit and scope of this utility model should be covered within the scope of the claims of this utility model; technologies not described in detail in this utility model are implemented using existing technologies.
