Shielding door control system, shielding door device and shielding door control method

Abstract

The invention relates to the field of pneumatic control, and particularly relates to a shielding door control system, a shielding door device and a shielding door control method. The shielding door device comprises a door frame and door leaves, wherein two sets of sliding block bases are assembled on the door frame; the sliding block bases can move up and down and are provided with dovetail grooves; two fixed sliding rods are installed on the door leaves; a sliding block in match with the sliding block bases is designed on the sliding rods; and the shielding door device further comprises a shielding door control system which comprises a cylinder, two five-way valves, a first door opening button, a second door opening button, a shuttle valve, a mechanical valve, an air reservoir barrel, a spring reset valve, a first logic valve and a second logic valve. The closing and the opening of a shielding door are realized by using the shielding door control method. With the adoption of the shielding door control method, the system and the device, the operation strength of the shielding door during a door opening and closing process is reduced greatly; the shielding door is good in tightness, needs no power, and is high in security and strong in reliability; and the condition that operation personnel is counter-locked is avoided.

Description

technical field [0001] The invention relates to the field of pneumatic control, in particular to a screen door control system, a screen door device and a screen door control method. Background technique [0002] At present, domestic screen doors mainly adopt two ways of manual opening and electric opening. [0003] The screen door of the manual opening mode is divided into two parts: the door frame and the door leaf. Two sets of fixed slider seats with dovetail grooves are installed at both ends of the door frame, and a sliding bar that can move up and down is installed on the door leaf, and sliders matching the dovetail grooves at both ends of the door frame are installed at both ends of the sliding bar. A handle is installed in the middle of the sliding rod of the door leaf, and the handle is turned to drive the sliders at both ends of the sliding rod to slide in the dovetail groove of the door frame, so that the door leaf is detached from the door frame or locked.

AI Technical Summary

Problems solved by technology

The screen door with manual opening is laborious to open and close, and in order to save effort for the user to open and close the door manually, the degree of sealing must be controlled, but this will affect the sealing effect of the screen door; the screen door with electric opening needs to provide power. The screen door cannot be opened, and the reliability is low, and the screen door as a whole is a metal structure, there is a potential safety hazard of leakage, and the safety is low
