Abstract
The utility model discloses a pneumatic ball-shaped reversing valve structure. The pneumatic ball-shaped reversing valve structure comprises a lower valve body, a sealing connecting sleeve, and an upper valve body, wherein a connecting hoop which is used for connecting the lower valve body, the sealing connecting sleeve and the upper valve body together in a sealing mode is arranged outside the lower valve body and the upper valve body, the side face and the bottom face of the lower valve body are respectively provided with a material inlet and a material outlet, the side face of the upper valve body is provided with a material outlet, a valve core is respectively arranged inside the lower valve body and the upper valve body, the bottom end of each valve core is provided with a sealing ring capable of dynamically switching sealing rings of the material inlet and the material outlet at the bottom end of the lower valve body, the top end of each valve core extends out of the sealing ring of the upper valve body, a connecting support frame is arranged outside the upper valve body, a pneumatic mechanism is installed on the connecting support frame, and the top end of each valve core is provided with connecting threads which are connected with threaded holes inside a pneumatic rod of the pneumatic mechanism. The reversing valve is convenient to install and detach when needing to wash and maintain, capable of satisfying demands of a sanitary valve of industrials such as food and beverage, dairy products, medical treatment, brewage, pharmacy, cosmetics, bioengineering, medicine, and fine chemical engineering.
Description
Technical field
The utility model relates to the valve mechanism field, relates in particular to a kind of pneumatic spherical structure of reversing valve.
Background technique
Selector valve is a kind of valve for changing liquid flow direction, selector valve has a plurality of adjustable passages, can change direction of flow by the driving mechanism switching channel, realized the purpose that periodic transformation flows to, wherein, pneumatic reversing ball valve is widely used in the industries such as food and drink, milk product, medical treatment, brewing, pharmacy, cosmetics, bioengineering, medicine and fine chemistry industry.But existing pneumatic spherical structure of reversing valve more complicated, the installing/dismounting of the parts such as its inner spool and piston rod is inconvenient, and more complicated when maintenance is cleaned requires further improvement.
Summary of the invention
For overcoming the deficiencies in the prior art, it is a kind of simple in structure that the utility model provides, and is convenient to clean, keep in repair the pneumatic spherical structure of reversing valve of mounting or dismounting.
The utility model is to reach the technological scheme that above-mentioned technical purpose adopts to be: a kind of pneumatic spherical structure of reversing valve, comprise lower valve body, sealed adapter sleeve, upper valve body, lower valve body and upper valve body are provided with jointing clip outward with lower valve body, sealed adapter sleeve, upper valve body is sealed connected together, the side of described lower valve body and bottom surface are arranged with a material feeding mouth, discharge port, the upper valve body side is provided with a discharge port, be provided with spool in described lower valve body and the upper valve body, the bottom of described spool is provided with the seal ring that can dynamically switch the lower valve body bottom of sealing feed inlet and outlet, stretch out in the seal ring of the top of wherein said spool from upper valve body, upper valve body is provided with connection bracket outward, pneumatic mechanism is installed on the connection bracket, and the tapped hole that the top of described spool is provided with in the cylinder column of connecting thread and pneumatic mechanism links to each other.
Seal ring on the described spool is the EPT rubber packing circle.
The beneficial effects of the utility model are: adopt said structure, tapped hole in connecting thread and the cylinder column is set on the top of spool, selector valve needs to clean, make things convenient for installing/dismounting when keeping in repair, and can satisfy the requirement of the industry sanitation-grade valves such as food and drink, milk product, medical treatment, brewing, pharmacy, cosmetics, bioengineering, medicine and fine chemistry industry.
