The pneumatic locking device comprises an unlocking valve A, a linkage member A and a magnetic control valve A mounted on a door A and an unlocking valve B, a linkage member B and a magnetic control valve B mounted on a door B, wherein the magnetic control valve A and the magnetic control valve B are connected with a control air source through a three-way valve at the same time; an air path is connected with a linkage device B through the magnetic control valve B and the unlocking valve B and then connected with a linkage device A through the magnetic control valve B and the unlocking valve A; the linkage device A and the linkage device B are provided with a cylinder respectively; plug pins controlling the opening/closing of the doors are respectively arranged at the front end of the corresponding cylinder; the door A is also provided with a magnetic induction member A for inducing the opening/closing of the door; and the door B is also provided with a magnetic induction member B for inducing the opening/closing of the door. The pneumatic locking device provided by the utility model does not need electricity, prevents potential safety hazard, and is suitable for high and low-gas mines. Moreover, the pneumatic locking device has good locking effect, reliable performance and long service life, and effectively prevents short circuit of air flow when the two doors are opened at the same time.
Description
Technical field
The utility model belongs to the control device of door, relates to a kind of pneumatic locking device.
Background technology
Well depth lane, domestic many collieries is far away at present, need constantly strengthen ventilation, makes also increasing thereupon of pressure reduction before and after the air door between air intake lane, the return airway.Therefore the sealing to air door proposes higher requirement.Ventilation system has many connections lane under the coal mine, and the per pass air door must good seal.The sealing problem that numerous air doors exist certainly will cause the down-hole air feed system disorderly.Therefore, current is two major functions that are connected the lane air door with sealing.
At present, the non-pressure damper in the mine often latch effect is bad, has the twice air door sometimes and opens simultaneously, causes the distinguished and admirable short circuit in down-hole.And automatically controlled block sytem needs waterproof and dampproof dependable performance, otherwise system disorders, electric elements reduce application life greatly.
Summary of the invention
The utility model provides a kind of simple in structure, easy to use, reliable pneumatic locking device of locking in order to remedy the deficiency of prior art.
The utility model is realized through following technical scheme:
The pneumatic locking device of the utility model; Its special character is: comprise being installed in and separate locking-valve A, STATEMENT OF FEDERALLY SPONSORED A and magnetic control valve A on the A; And be installed in and separate locking-valve B, STATEMENT OF FEDERALLY SPONSORED B and magnetic control valve B on the B; Magnetic control valve A is connected the control source of the gas with magnetic control valve B through tee piece simultaneously, and gas circuit also connects linkage B through separating locking-valve B behind magnetic control valve A, and gas circuit also connects linkage A through separating locking-valve A behind magnetic control valve B; Linkage A and linkage B are respectively equipped with cylinder; The cylinder front end is provided with the latch of the switching of control place door, and the magnetic induction part A of the switching that is used for induction door also is installed on the door A, and the magnetic induction part B of the switching that is used for induction door also is installed on the door B.
The beneficial effect of the utility model is, belongs to pure frame for movement, do not need electricity, no potential safety hazard, and high and low gassy all can use.Effectively overcome non-pressure damper locking defect of bad, dependable performance need not done waterproof and dampproof processing.Simple in structure, be easy to learn and use, can solve long service life after breaking down at any time.This device can be installed on facility places such as single pectinid door, two-way non-pressure damper, distinguished and admirable short circuit when preventing effectively that the twice air door from opening simultaneously.
Description of drawings
Fig. 1 is the system principle sketch map of the utility model.
Among the figure, 1 source of the gas, 2 air circuit breakers, 3 pressure regulator valves, 4 tee pieces, 5 STATEMENT OF FEDERALLY SPONSORED A, 6 baffle plate A, 7 separate locking-valve A, 8 magnetic-inductive device A, 9 magnetic control valve A, 10 A, 11 STATEMENT OF FEDERALLY SPONSORED B, 12 baffle plate B, 13 separate locking-valve B, 14 magnetic-inductive device B, 15 magnetic control valve B, 16 B.
The specific embodiment
Accompanying drawing is a kind of specific embodiment of the utility model.
The pneumatic locking device of the utility model; Comprise being installed in and separate locking-valve A 7, STATEMENT OF FEDERALLY SPONSORED A 5 and magnetic control valve A 9 on the A 10; And be installed in and separate locking-valve B 13, STATEMENT OF FEDERALLY SPONSORED B 11 and magnetic control valve B 15 on the B 16; Magnetic control valve A 9 is connected control source of the gas 1 with magnetic control valve B 15 through tee piece 4 simultaneously, and gas circuit also connects linkage B 11 through separating locking-valve B 13 behind magnetic control valve A 9, and gas circuit also connects linkage A 5 through separating locking-valve A 7 behind magnetic control valve B 15; Linkage A 5 and linkage B 11 are respectively equipped with cylinder; The cylinder front end is provided with the latch of the switching of control place door, and the magnetic induction part A 8 of the switching that is used for induction door also is installed on the door A, and the magnetic induction part B 14 of the switching that is used for induction door also is installed on the door B.
The pneumatic locking device of the utility model, source of the gas 1 be through behind air circuit breaker 2 and the pressure regulator valve 3, is connected through between tee piece 4 and a door A and the B gas circuit, promptly connects magnetic control valve A and magnetic control valve B simultaneously through tee piece.On the door A 10 the baffle plate A 6 that is used to locate is installed, on the door B 16 the baffle plate B 12 that is used to locate is installed.
Operating principle: when A door and B door simultaneously in off position the time, air door is in released state, and A door or B door are any can both be opened together.When the A door was opened, source of the gas was opened in magnetic control valve A (being installed on the A door) action, and after STATEMENT OF FEDERALLY SPONSORED B obtained pressure air, latch extended under the drive of cylinder, and the B door lock is dead.After the A door was closed, magnetic patch valve A resetted source of the gas is broken, and STATEMENT OF FEDERALLY SPONSORED B resets, the release of B door.If the A door is not closed completely, goalkeeper B can't open, and at this moment the pedestrian can separate locking-valve B through pressing, and STATEMENT OF FEDERALLY SPONSORED B resets, the release of B door.Otherwise, as the same when the B door is opened.
