Described automatic retractable safety valve system comprises valve body and is arranged on the valve rod in valve body, and valve body is divided into upper and lower two independently cavitys by valve rod, is controlled the folding of fast-opening blind by the movement of valve rod in upper and lower cavity.
Described second oil cylinder is connected as a single entity by support and ball valve.
Described valve limits mechanism and comprises the ball valve worm screw be connected with ball valve, and the other end of ball valve worm screw is connected with ball valve handwheel, and ball valve worm screw and ball valve worm screw fixed tray are connected as a single entity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
As Fig. 1, a kind of Novel pure door mechanical type safety interlocking device, comprise shell 1, the ball valve 2 be connected with shell 1, be arranged on the fast-opening blind 8 on shell 1, described ball valve 2 is provided with valve and limits mechanism 4 and limit with valve the ball valve worm screw fixed tray 6 that mechanism 4 is fixedly connected with, be connected with between ball valve 2 and fast-opening blind 8 and limit mechanism 4 for limiter valve thus the inlet valve control mechanism 5 controlling shell 1 air inlet, fast-opening blind 8 be provided with for by its locked on shell 1 or from shell 1 discharge automatic retractable safety valve system 3.
Described inlet valve control mechanism 5 comprises and has the first oil cylinder 51 of first piston bar 512 by oil pipe is interconnective and has the second oil cylinder 52 of the second piston rod 521, first oil cylinder 51 is provided with the import piston 513 be connected with fast-opening blind 8, first oil cylinder is connected as a single entity by the screw thread of lower end and fast-opening blind shell flange, second oil cylinder 52 is connected with the outlet piston 522 for stuck ball valve worm screw fixed tray 6, second oil cylinder 52 is connected as a single entity by support 7 and ball valve 2, and described outlet piston 522 is arranged in a crossed manner with ball valve worm screw fixed tray 6.
Described automatic retractable safety valve system 3 comprises valve body 31 and is arranged on the valve rod 32 in valve body 31, valve body 31 is divided into upper and lower two independently cavitys 311,312 by valve rod 32, is controlled the folding of fast-opening blind 8 by the movement of valve rod 32 in upper and lower cavity 311,312.
Described valve limits mechanism 4 and comprises the ball valve worm screw 41 be connected with ball valve 2, and the other end of ball valve worm screw 41 is connected with ball valve handwheel 42, and ball valve worm screw 41 and ball valve worm screw fixed tray 6 are connected as a single entity.
Working method:
When fast opening type pressure container fast-opening blind is in open mode, equipment importation ball valve is in closed condition, and on quick operating valve, lock ring is in contraction state.In closedown fast-opening blind process, lock ring will change enlarged state into from contraction state, thus promotion first piston moves upward, and then impel the first in-oil cylinder oil to reach the second oil cylinder by oil guide pipe, and then cause the second piston to move right, and then the second piston comes off from the hole ball valve worm screw fixed tray; Now, ball valve handwheel can rotate, and can open ball valve and make equipment air inlet.So, then the requirement of " close position when quick operating valve reaches predetermined, can booste operation " is met.
When equipment inner chamber enters cavity of resorption without pressure by import, valve rod is in low level, and valve rod does not stretch out outside epicoele; When equipment inner chamber has pressure to enter cavity of resorption by import, valve rod moves upward under interior pressure effect, and flexible rod stretches out outside epicoele, and now extension is just pressed in above breaker bolt, and then breaker bolt can not be pulled down from the end cap of fast-opening blind, and then fast-opening blind cannot be opened; So, then the requirement of " when the internal pressure of pressurized container does not discharge completely, quick operating valve can not be opened " is met.
When the fast-opening blind being in closed condition need be opened, need first inlet ball valve to be closed, drain the pressure of shell inner chamber, just can carry out the operation of opening fast-opening blind.Concrete steps are as follows: shrink lock ring, lock ring will disappear to first piston support force upwards, and the second piston to left movement, and then will insert the hole on ball valve worm screw fixed tray; So, then the requirement " close position when quick operating valve does not reach predetermined, can not booste operation " is realized.
