Abstract
The utility model relates to a lock type safety valve which can not be opened freely and compreses that a valve body is provided with a complete set of lock type mechanism opened by a key, the rack of a valve rod is directly matched and rotated with the gear of a lock core to cause the valve rod to slide up and down, and one side of the valve is provided with a lock type device; the gear of the lock is engaged with the gear of the valve rod, and the key can be used to open the lock to drive the gear of the valve rod to rotate a handle to move the valve body up and down. The utility model has the advantages that the user can see the open or close state of the lock in using, and the key can be fetched in closing the valve without causing the overflow phenomena of the gas, the oil and the water.
Description
The utility model relates to a kind of guarantor's the life and the locking-type safety valve of national wealth safety.
At present, the valve of generally acknowledging can be with anxious switch, uses incorrectly just can cause excessively, or forget and close, and the bad person utilizes it to put poison, and sets fire, and pilferage brings very big loss to the people's life and national wealth.
In order to address this problem, utilize the structure of lock to come the switch of control valve, there is not the key valve not open, key can not take out when opening, and has only that key could take out when correctly closing, and realize that this control system will be very difficult.
The purpose of this utility model provides a kind of arbitrarily switch of key that do not have, and has only that key could take out when correctly closing, the locking-type safety valve no matter anyone can both correctly use.
The purpose of this utility model is achieved in that a kind of locking-type safety valve, and valve rod is provided with a cover locking-type opening mechanism, and Fig. 1 is the lock that is installed on the valve casing, locks to have a gear, and have tooth bar with its engagement on valve rod.Fig. 2 has gear on the valve rod, on valve casing one side pin is arranged, and locks to have the gear that is meshed with gear on the valve rod.
Owing to adopt such scheme, its advantage is that the people can correctly use it, simultaneously also can see whether closing, key takes out when closing, be unlikely to cause the excessive phenomenon of gas, oil, water, have this structure stopped children play with fire with gas-tank and gas pipe line and cause the damage and the loss, main is to prevent that the bad person from putting poison, set fire, stealing.Guaranteed the safety of people's life and national wealth.
The concrete structure of model utility is provided by following two embodiments and accompanying drawing.
Fig. 1, Fig. 2 are two optimum implementation plane structure schematic representation of the present utility model.
In this Fig. 1 valve rod (3) being put into valve casing (2) key (6) insertion lock (7) driven gear (5) interlock tooth bar (4) by valve gap (1) makes it to slide up and down, prevent the gas overflow by seal ring (8), sealing gasket (10) prevents that gas is excessive, enter hole (11) and connect gas tank, the gas bucket, portal (9) connect reduction valve.
Key among Fig. 2 (12) inserts lock stamen (16) moves up and down valve body (17) by making lock gear (14) start valve rod gear (15) handle with sleeve (13), enters hole (18) and takes over road one end, and portal (19) take over the road the other end.
Fig. 1 is useful for gas-tank, oxygen cylinder, acetylene cylinder.Fig. 2 is useful for outdoor gas pipe line, oil transport pipeline, gas pipeline.
