Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model. The utility model will be further described with reference to the accompanying drawings and examples:
example 1:
referring to fig. 1, a valve pressing machine safety protection device comprises;
the installation frame 1, the installation frame 1 is arranged on the upper pressing plate of the valve pressing machine so that the installation frame 1 and the upper pressing plate of the valve pressing machine do synchronous motion.
The protective cover 2 is arranged on the mounting frame 1 and is arranged outside the upper pressing plate of the valve pressing machine and is used for protecting the valve in the leakage process so as to prevent the valve from leaking and producing water and gas splashing; the protection cover 2 is made of transparent materials so as to observe the testing state of the valve in the valve testing process, and the main body of the protection cover 2 is round or rectangular, and the protection cover 2 is preferably round in shape in the design.
