Abstract
The utility model relates to a non-removable device for connecting a non-repeat filling cylinder valve for industry use with a cylinder body, and, i.e. a device for connecting disposable cylinder valve with cylinder valve seat. Primarily, the lower side wall of a connecting cavity for a cylinder valve seat which is connected with a suction nozzle of a disposable cylinder valve by screws is provided with a ring groove and the bottom of the connecting cavity is provided with a latch fitting that is opposite to the suction nozzle. When the suction nozzle tightly butts on the latch fitting, the external port of the suction nozzle struggles to get free towards the periphery of the ring groove, therefore, the suction nozzle is locked and free from backspin, and the possibility of reusing a copper cylinder is avoided. The utility model has the advantages of simple structure, low cost, convenient operation, etc., being used for connecting a disposable steel cylinder and a cylinder valve.
Description
The utility model relates to the connection set between cylinder for liquefied gas valve and the steel cylinder, the non-removable connection between particularly industrial cylinder valves for non-refillable cylinder and the bottle.
Being connected between existing industrial cylinder valves for non-refillable cylinder and the bottle by screw fixed, can dismantle between cylinder valve and the bottle, steel cylinder can be repeated inflation and use, and this lacks general Security for the cylinder for liquefied gas that specific (special) requirements is arranged, as the cylinder for liquefied gas of disposable usefulness.
The purpose of the utility model is to provide the connection set between a kind of disposable cylinder valve simple in structure, non-removable and the cylinder valve seat, to prevent that cylinder for liquefied gas is repeated to use.
The technical solution of the utility model is such: it mainly has ring recess chewing on the cylinder valve seat connection chamber lower sides that is threaded with disposable cylinder valve air inlet, is provided with air inlet in the connection chamber bottom and chews relative latch fitting.When air inlet is chewed spiral and is held out against on latch fitting, the port that air inlet is chewed is earned out around ring recess under the effect of latch fitting, thereby destroyed air inlet and chewed screw-thread fit between original outside thread and the cylinder valve seat connection chamber, making air inlet chew can not withdraw from by backspin, thereby has avoided steel cylinder to be repeated to inflate the possibility of use.
Below in conjunction with embodiment shown in the drawings, the utility model is described in further detail.
Not ruined structural representation when Fig. 1 is the utility model assembling;
Fig. 2 is the structural representation after the utility model assembles fully.
Connection set between disposable cylinder valve and the cylinder valve seat comprises the disposable cylinder valve and the cylinder valve seat 9 that is fixed on the cylinder for liquefied gas of non-refillable.Disposable cylinder valve is by valve body 3, and the valve rod 2 that has handle 1 is formed with the spool 5 that is contained in valve rod 2 tops.Valve body 3 has air inlet and chews 8 and give vent to anger and chew 14, and air inlet is chewed 8 and chewed 14 and communicate with giving vent to anger by valve body 3 valve pockets 7.Spool 5 places in the valve pocket 7, and gapped with valve pocket 7 sidewalls, and garden platform shape is made on spool 5 tops, is embedded with O-ring seals 6 on it; Between valve rod 2 tops and valve body 3 inwalls O-ring seals 13 is housed, can seals lifting in order to make valve rod 2; Valve rod 2 and spool 5 pins 4 made of plastic are connected, and when spool 5 does not push up when being combined in air inlet and chewing 8 inner port, as shown in Figure 1, disposable cylinder valve can be by 11 pairs of pneumatic inflations of air outlet hole of cylinder valve seat 9; When spool 5 under the drive of valve rod 2, when involution is chewed 8 inner port in air inlet, steel cylinder is closed, at this moment, if continue rotary valve rod 2 handles 1, plastic pin 4 is broken by button, spool 5 separates with valve rod 2, and as shown in Figure 2, valve rod 2 can not drive spool 5 and rise, after this this cylinder valve can only be made one-way valve and use, and promptly can not inflate once more steel cylinder by this cylinder valve.
Cylinder valve seat 9 has ring recess 16 on the connection chamber lower sides, the bottom is provided with inlet hole 11 and chews 8 relative garden platform shape latch fittings 10 with valve body 3 air inlets, the minimum outer diameter of garden platform shape latch fitting 10 is chewed the internal diameter of 8 external port less than air inlet, chew 8 when holding out against on latch fitting 10 to guarantee air inlet, air inlet is chewed 8 external port and is earned out around ring recess 15 along latch fitting 10 garden platform sidewalls, makes air inlet chew 8 and is locked on the cylinder valve seat 8 and can not normally dismantles.
The utility model is equipped with limiting stopper 12 between handle 1 and valve body 3 tops before installation, prevent that cylinder valve from before not to pneumatic inflation, just having twisted into two parts plastic pin 4.
Obviously, the utlity model has simple in structure, easy to use, low cost and other advantages, be fit to In being installed in the disposable steel cylinder of industrial upper use and being connected of cylinder valves for non-refillable cylinder.
