Problems solved by technology
When these valves discharge materials that are easy to crystallize, there is a space between the valve core and the discharge port of the barrel. The material in this space cannot be stirred, so it is easy to crystallize and solidify, thus blocking the valve and the discharge port.
When opening the discharge valve to discharge, it is often necessary to manually remove the clogged crystals, resulting in a reduction in production efficiency
In addition, the internal structure of these discharge valves is complicated, the cleaning and disinfection are not thorough, and dirt is easy to hide, which affects the quality of the product

Embodiment Construction
[0014] The present invention will be further described below in conjunction with the accompanying drawings.
[0015] As shown in the figure, a pneumatic swing-up discharge valve includes a cylinder body 3, a bracket 7 and a valve body 9, and the cylinder body 3, the bracket 7 and the valve body 9 are fixed by bolts. The upper end of the cylinder body 3 is fixedly provided with an upper cylinder head 6, the lower end is fixedly provided with a lower cylinder head 1, and a supporting bolt 4 is arranged between the upper cylinder head 6 and the lower cylinder head 1, and the supporting bolt 4 plays an integral supporting role. The upper cylinder head 6 is provided with a first air inlet 16 , and the lower cylinder head 1 is provided with a second air inlet 17 .
[0016] A valve is arranged on the top of the valve body 9, and a flow channel communicating with the valve is arranged inside the valve body 9. A valve rod 5 is arranged through the cylinder body 3 , the bracket 7 and t...

The invention discloses a pneumatic swing type open upward discharge valve, and belongs to the technical field of valves. The pneumatic swing type open upward discharge valve comprises a cylinder, a bracket and a valve body, wherein a valve rod is arranged in the cylinder, the bracket and the valve body in a penetration mode; the bottom of the valve rod is fixedly provided with a piston; the piston is matched with the cylinder; the top of the valve rod is provided with a valve element in a matched mode; the valve element is matched with the top valve of the valve body; a cylindrical pin is fixedly arranged on the valve rod; the top of the valve rod is connected with a rotary shaft in a sleeving mode; symmetrical spiral slide paths are arranged on the rotary shaft; the cylindrical pin is inserted into the bottom ends of the two spiral slide paths in a penetration mode; and a fixed valve element is connected outside the rotary shaft in the sleeving mode. The pneumatic swing type open upward discharge valve is simple in structure and reasonable in design; the cylindrical pin and the rotary shaft matched with the cylindrical pin are arranged on the valve rod, so that in the valve rod ascending process, the valve element can rotate to guarantee that a medium which is easy to crystallize is not solidified, and therefore, a runner is smooth, valve blocking is not liable to appear, and the normal use of the valve is guaranteed.
Description
technical field [0001] The invention belongs to the technical field of valves, and in particular relates to a pneumatic swing-up discharge valve. Background technique [0002] Common discharge valves on the market are butterfly valves, ball valves, gate valves, etc. When these valves discharge materials that are easy to crystallize, there is a space between the valve core and the discharge port of the barrel. The material in this space cannot be stirred, so it is easy to crystallize and solidify, thereby blocking the valve and the discharge port. When the discharge valve is opened to discharge, it is often necessary to manually remove the clogged crystals, resulting in a reduction in production efficiency. In addition, the internal structure of these discharge valves is complicated, the cleaning and disinfection are not thorough, and dirt is easy to hide, which affects the quality of the product. Contents of the invention [0003] Aiming at the problems existing in the p...
