Problems solved by technology
[0004] At present, from a safety point of view, there are also examples of integral reversing pneumatic valves with additional overload protection functions or emergency stop protection functions. The more complex the channel structure, the more difficult it is to process. The valve body blank is generally cast, and the casting blank will inevitably have casting defects such as sand holes and pores. Air and air leakage will not have much impact on its overall function, but the multi-functional reversing valve body is different. A slight string or air leakage inside will affect the realization of logic action, resulting in the scrapping of the entire valve body, and the overall The multi-functional reversing pneumatic valve has no optional additional functions, and users cannot choose the additional functions of the reversing pneumatic valve according to their needs. The valve body with various functions is designed separately, the product cost is high, and it is not conducive to large-scale production.

Embodiment Construction
[0032] The present invention is described in detail below in conjunction with accompanying drawing and specific embodiment:
[0033] Such as Figure 1-9 As shown, the multifunctional reversing pneumatic valve includes a valve body 1, an air supply valve core 2, a reversing valve core 3 and an operating handle 4. The air supply valve core 2 is arranged in the upper cavity of the valve body 1, The main air supply valve opening air cavity 11 is formed between the left end of the air supply valve core 2 and the valve body 1, and the right end makes the main air channel 25 and the main air supply channel 12 form a non-fixed sealing relationship through the sealing disc 21, and the reversing The valve core 3 is arranged in the lower cavity of the valve body 1, and the valve body 1 is pressed into the valve sleeve 5 in a press-fitting manner, and the air passage of the valve sleeve 5 forms a fixed communication relationship with the air passage of the valve body 1, so The reversing ...

The invention discloses a multifunctional reversing pneumatic valve, relates to the application field of pneumatic equipment, and designs a reversing pneumatic valve with simple structure and various functions. Exhaust reversing function, as well as additional functions such as overload protection, emergency stop protection, air-cut brake control, etc. The emergency stop protection module and overload protection module that are compatible with the reversing pneumatic valve adopt an independent modular structure design. One or two functional modules can be selected for combined application with the main body of the pneumatic reversing valve. The structure is simple, easy to use, and has a wide range of applications. Users do not need to separately design or purchase a reversing pneumatic valve with one function, which greatly reduces The cost is reduced and the utilization rate of the pneumatic reversing valve is improved.
Description
technical field [0001] The invention relates to the application field of pneumatic equipment, in particular to a multifunctional reversing pneumatic valve. Background technique [0002] Due to the excellent explosion-proof performance of pneumatic components, pneumatic control and pneumatic machinery are widely used in all aspects of production and life. Pneumatic actuators such as cylinders and air motors are important power units of pneumatic machinery. The reversing valve in its control system plays a vital role in the operating efficiency and safety of pneumatic machinery. The usual reversing valve generally only has , exhaust reversing and a certain sense of flow control function, the actual control function is poor, and there is no safety protection function, such as the release speed under load is not easy to control, misoperation and control jamming are prone to danger, unlimited overload timeout Running, etc., there is a great security risk. [0003] In addition, ...
