Abstract
The utility model discloses a locking valve for liquified-gas cylinders, which comprises a valve handle, a valve body and a joint body, wherein the lower face of the valve handle is fixedly connected with a guide rod, a notch is arranged on the upper part of an air outlet of the guide rod, a rack which can be inserted into the notch is installed on the valve body, and a gear engaged with the rack is installed on a lock core. When the utility model is in a closed state, the lock core is rotated by a key, the rack is inserted into the notch in the guide rod so that the guide rod can not rotate, and the utility model is locked. Therefore, the utility model avoids accidents caused by arbitrary opening of the valve by people without the ability to use liquified gas, having the advantages of simple structure, low cost, easy use and safety as well.
Description
The utility model belongs to a kind of valve, belongs to a kind of Locked valve that is used on the cylinder for liquefied gas specifically.
Cylinder for liquefied gas has been widely used in the family life of urban and rural residents, use is played convenient and healthy, time saving and energy saving, but because of liquid gas poisonous inflammable, the time have accidents such as poisoning that gas leak causes and fire explosion to take place, cause personal injury and economic loss, so, many children of having, obnubilation and amnesia patient's family uses to play worry more, have in addition dare not use.
The purpose of this utility model is to provide a kind of arbitrarily that rotate, safe and reliable lockable valve that prevents.
The purpose of this utility model is achieved in that and comprises valve handle, valve body and fittings body, guide rod is fixedly connected below the said valve handle, this guide rod outside is said valve body, these valve body both sides have pole to connect with support plate on the said fittings body, top, air outlet at said guide rod is jagged, the tooth bar that can insert in the breach is installed on the said valve body, and the gear that is meshed with this tooth bar is installed on the lock core of available key turns.During use, fittings body is connected on the cylinder for liquefied gas, for preventing from arbitrarily to open valve, during without liquid gas, rotate valve handle and make valve be in closed condition, make the gap position on the guide rod corresponding this moment with the tooth bar position, use key rotation lock core, then the gear of lock core top rotation can't rotate guide rod the indentation, there in the tooth bar insertion guide rod that is engaged with, and valve is lockable.
Advantage of the present utility model is: behind throttle down, the key of can whipping is pinned valve, effectively prevent from not have the random Open valve of people that uses the liquid gas ability and cause the contingency generation, avoided unnecessary casualties and economic loss, and it is simple in structure, cost is low, and is easy to use, safe and reliable.
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is a plan view of the present utility model.
Fig. 2 is a left view of the present utility model.
As shown in Figure 1 and Figure 2, guide rod 10 is fixedly connected below the valve handle 1, guide rod 10 bottoms are suction port 4, there is air outlet 12 centre, and the outside is a valve body 9, and there has been the pole 2 of fixation valve body 9 both sides, support plate 3 scyewed joint of welding on the fittings body 11 of pole 2 and valve body 9 bottoms, jagged 5 on 12 tops, air outlet of guide rod 10, the tooth bar 6 that can insert in the breach 5 is installed on valve body 9, the gear 7 that is meshed with tooth bar 6 is installed on the lock core 8 of available key turns.During use, fittings body 11 is connected on the cylinder for liquefied gas, and air outlet 12 links to each other with the liquid gas conduit, for preventing from arbitrarily to open valve, during without liquid gas, rotate valve handle 1 and make valve be in closed condition, make the position of the breach 5 on the guide rod 10 just in time corresponding this moment, with key rotation lock core 8 with tooth bar 6 positions, then lock core 8 drives gear 7 rotations on top, gear 7 can't rotate guide rod 10 breach 5 places that the tooth bar 6 that is engaged with inserts in the guide rod 10, and valve is lockable.This Locked valve is simple in structure, and cost is low, and is easy to use, safe and reliable.
