Description of the drawings
Fig. 1 is the principles of the present invention schematic diagram.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
As shown in Figure 1, the utility model provides a kind of technical solution：A kind of air door automatic gas control delay lock device, packet
Include the first jettron 1 on the pectinid door, the first rotary cylinder 2, second be mounted on another pectinid door be pneumatic
Switch 3 and the second rotary cylinder 4, and the centralized control cabinet between two pectinid doors, the first jettron 1, the first rotation
Rotaring cylinder 2 is connected between second jettron 3 and the second rotary cylinder 4 and centralized control cabinet by tracheae.
Particularly, the centralized control cabinet includes cabinet 5, the air filtration pressure reducing valve 6 being mounted in cabinet, the first gas
Control reversal valve 7 and the second Pneumatic reversal valve 8,9 one end of compressed air inlet pipe are connected to compressed air source, and the other end is sequentially connected
Check valve 10 and multiple time-delay mechanisms 11 are followed by the air inlet of air filtration pressure reducing valve, and multiple time-delay mechanisms are that volume is larger
Caisson (such as air accumulator, air storage bag etc.) will first store up full before compressed air is sent into air filtration pressure reducing valve in caisson
Compressed air is spare, and when compressed air source deactivates, caisson can be used as spare compressed air source to continue to blocking device
Gas supply, air filtration pressure reducing valve is realized is filtered decompression to the compressed air of feeding, gas outlet by three three-way pipes or
One Five-way tube of person is divided into four road outlets and is respectively fed to the first jettron, the second jettron, the first Pneumatic reversal valve and
Two Pneumatic reversal valves, the first Pneumatic reversal valve and the second Pneumatic reversal valve are two-position five-way Pneumatic reversal valve.
First jettron, 1 and second jettron 3 is TAC-3V two position three-way valves, is prolonged mounted on air door inner side edge
(side of installation hinge), to detect whether air door is opened, the air inlet of the first jettron connects air filtration pressure reducing valve,
Gas outlet connects the second ports Pneumatic reversal valve A by tracheae, and the second jettron air inlet connects air filtration pressure reducing valve, goes out
Gas port connects the ports A of the first Pneumatic reversal valve, when air door is opened, the spring lever bullet of corresponding jettron by tracheae
It rises, the air inlet of jettron and gas outlet communicate so that the compressed air for being sent into jettron is sent to the gas control being correspondingly connected with
Reversal valve is realized to the commutation control of Pneumatic reversal valve, after air door closing, spring lever compression, the air inlet of jettron and
Gas outlet disconnects, to which Pneumatic reversal valve resets.
The outer side edges that first rotary cylinder and the second rotary cylinder are mounted on air door prolong (opening side), rotary cylinder
L-type locking plate 12 is installed on swivel head, makes locking plate block doorframe, first rotation by the different rotary position of L-type locking plate
Two air inlets of rotaring cylinder are separately connected two interfaces of the first Pneumatic reversal valve, two air inlets point of the second rotary cylinder
Two interfaces for not connecting the second Pneumatic reversal valve change the gas circuit side of two interfaces by the switch operation of Pneumatic reversal valve
To realize that the rotation to rotary cylinder controls.
Since two pectinid doors can not open simultaneously, so devising side in gas circuit control opens another side chain
Tightly, it however (such as needs to transport the article of long size) in some special circumstances, needs to open simultaneously two pectinid Men Caike, and
Existing gas circuit design cannot achieve, so adding three-way ball valve 13 between rotary cylinder and Pneumatic reversal valve, need
When opening simultaneously two pectinid doors, the ball valve of that pectinid door of locking is closed, the air inlet of rotary cylinder is blocked, to
It pushes locking plate aside manually and realizes that two pectinid doors open simultaneously.
In view of needing to stop the supple of gas or steam when repair, in order to ensure that two pectinid doors do not influence to use, in compressed air inlet pipe
Entrance is additionally arranged caisson, and coordinates check valve, and after gas deactivates, the compressed air in caisson is as bailout gas
Continue to supply entire gas circuit use, the caisson of not co-content can be selected according to the frequency of use of valve.
A kind of revealed air door automatic gas control delay lock device of the utility model, its working principle is that：Compressed air
It is sent by compressed air inlet pipe, caisson is full of while being sent into, it is corresponding pneumatically to open when a pectinid door is opened
Close triggering so that the compressed air for being sent into the jettron send Pneumatic reversal valve corresponding to another pectinid door, driving gas control to change
To Vavle switching inner air path, to drive corresponding rotary cylinder to rotate so that locking plate rotation lock, to another pectinid door nothing
Method is opened, and after open air door is closed, jettron disconnects, Pneumatic reversal valve switching gas circuit again so that rotary cylinder
Rotation is so that locking plate resets again, and two pectinid doors can be opened all in non-lock status at this time, once again by a pectinid door
It is secondary to be opened, it equally repeats another pectinid door of above-mentioned principle and is locked.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is appreciated that can these embodiments be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
