Novel pneumatic air valve remote control device

Abstract

The invention relates to a novel pneumatic air valve remote control device. An air bottle is divided into two paths which are connected with a manual stop valve and an electric stop valve respectively. The manual stop valve is communicated with an air inlet of a three-position five-way hand plate valve, two air outlets of the three-position five-way hand plate valve are connected with one air inlet of a first shuttle valve and one air inlet of a second shuttle valve respectively, and two air outlets of a three-position five-way electromagnetic valve are connected with the other air inlet of the first shuttle valve and the other air inlet of the second shuttle valve respectively; an air outlet of the first shuttle valve is divided into two paths which are connected with one air inlet of a locking shuttle valve and a first throttling valve respectively; an air outlet of the second shuttle valve is divided into two paths which are connected with the other air inlet of the locking shuttle valve and a second throttling valve; the first throttling valve is communicated with an inner cavity of one end of a piston of a locking air cylinder; the second throttling valve is communicated with an inner cavity of the other end of the piston of the locking air cylinder; an air outlet of the locking shuttle valve is communicated with a locking air inlet of the locking air cylinder through a two-position three-way pneumatic control valve; an air cylinder rod of the locking air cylinder drives a pneumatic air valve plate through a swing arm.

Description

technical field [0001] The invention relates to a damper control device, in particular to a switch device for remote manual and electric control of a pneumatic damper. Background technique [0002] The remote control device of the existing pneumatic air valve adopts a switch type cylinder, which has no locking effect, so that when the air source and power supply disappear, the opening and closing of the pneumatic air valve cannot be realized remotely. That is, it is not possible to open the air valve to exhaust air according to the needs of on-site exhaust air. In some existing remote-controlled pneumatic air valves, the fan is opened first, and the air is exhausted when the air valve is not opened. 1. Insufficiencies such as manual and electric remote control cannot be realized on the same device, and the control performance is poor. Contents of the invention [0003] In order to solve the problems in the prior art that the original opening and closing position of the a...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the disadvantages of the prior art that the original opening and closing position of the air valve cannot be maintained due to the disappearance of the air source and power supply, and that it cannot be interlocked with the fan to control the operation, the present invention provides a new type of remote control device for the pneumatic air valve to complete the remote pneumatic air valve. The one-time opening, closing and locking of the valve can meet the combined use of manual and electric control switching, realize the chain control with the fan, and the control is accurate, safe and reliable
