Valve and machining process thereof

Номер: CN116557561A
Автор: ZHANG NAIBO, LIU DEXIN, LU JINGSHAN
Принадлежит:

The invention provides a valve and a machining process thereof, and relates to the technical field of valve machining, the valve comprises a valve seat, a valve element and a valve element control assembly, the valve element is installed in the valve seat, the valve element control assembly comprises a rough adjustment assembly and a fine adjustment assembly, and the valve seat is further provided with an inner wall water and alkali removing assembly and an automatic impurity treatment assembly. The position of the valve element is roughly adjusted through the rough adjustment assembly, and then the position of the valve element is finely adjusted through the fine adjustment assembly, so that the problem that the valve element is damaged due to the fact that the valve element is directly moved in one step and the valve element is violently collided with an impurity block or a sodium hydroxide block due to large single-time valve element movement displacement is solved; and meanwhile, the ...

Vertical lifting container

Номер: CN115898193A
Автор: LIU DEXIN, LIU QINGCHAO, ZHANG YUEQIANG, WANG FEI
Принадлежит:

The vertical lifting container comprises a container body frame, a supporting table is arranged on the container body frame and used for containing trays, an electric door device is arranged at the bottom of the container body frame, and a balance weight device and an anti-falling device are arranged on the side face of the container body frame. The counterweight device has the beneficial effects that the counterweight device simultaneously moves along with the lifting platform and moves in the opposite direction, the output torque of the motor is effectively reduced, the power of the motor is reduced, the cost is saved, and the working efficiency is improved. The electric door device feeds back signals to the system through a sensing device of the electric door device to determine the state of the single door, so that the built-in single door is opened and closed, and the automation degree is improved. The anti-falling device adopts a mechanical and electrical detection mode to prevent ...
