Description
The utility model relates to a kind of lock catch type cylinder valve, particularly relates to a kind of lock catch type liquefied petroleum gas cylinder valve.
In the prior art, liquefied petroleum gas cylinder valve is made up of valve body, valve rod, sealing gasket, flange and switch handle, wherein valve body has an air outlet that the medial axis is vertical with the valve body medial axis, the valve rod lower end connects sealing gasket, valve stem tip is installed switch handle, by the rotary switch handle, valve rod is moved up and down, thus the valve port in the opening and closing of fault valve body, and its cylinder valve connects with bottle by screw thread.Its deficiency is: 1. its air outlet connects with left-hand thread with pressure governor, when changing bottle at every turn mounting or dismounting work all very hard, and be easy to cause and connect bad and leak gas; 2. valve port is rotated by thread belt ovable valve stem and sealing gasket and finishes seal operation, is easy to make the sealing gasket wearing and tearing and causes gas leakage; 3. do not have anti-explosion safety device, in steel cylinder transportation that gas is arranged and using process, because of the influence of external environment, the liquefied petroleum gas (LPG) in the steel cylinder is expanded, and might cause the steel cylinder blast, inadequately safety.
The purpose of this utility model is exactly in order to overcome deficiency of the prior art, provide a kind of safe and reliable, can realize the quick lock catch type cylinder valve of installing of pressure governor.
The purpose of this utility model is to realize by following technical measures: it is by valve body, valve rod and sealing gasket are formed, the lower end that it is characterized in that valve body is a suction port, the upper end is the air outlet, the sliding sleeve that cooperates with valve rod also is housed in body cavity, it is fixed in the inner chamber of valve body by the base of a band through hole, dress stage clip in the sliding sleeve, last cover valve rod, the valve rod top is provided with push rod, stretches out from valve port from bottom to top, and valve rod top is with sealing gasket, at ordinary times, under the effect of stage clip, sealing gasket on valve rod sealing valve port has only by the thimble in matching used a kind of fast-assembling pressure governor with it, from the air outlet push rod is depressed, could open valve port, have a mounting groove, be used for connecting with fast-assembling pressure governor snap close in outer, valve body air outlet.
The utility model can also be realized by following technical measures: also have a safety valve on the valve body, and safety valve and body cavity UNICOM, the axis of safety valve is vertical with valve axis.
Safety valve is made up of safety spring, pressure adjusting spring seat, safe spool and sealing gasket, safe spool end face is installed sealing gasket, by safety spring and pressure adjusting spring seat it is pressed on the relief port of safety valve and body cavity UNICOM, pressure adjusting spring seat band through hole, with the safety valve scyewed joint, can be by rotation pressure adjusting spring seat, the size of regulating the safety valve popping pressure.
The popping pressure of safety valve can be in the scope of 2.5-2.75MPa, when the gas pressure in the steel cylinder surpassed above-mentioned scope, safe spool was backed down, and gas releases by the through hole on the pressure adjusting spring seat, when the bottle internal air pressure was reduced to 2.5MPa, safety valve cut out under the effect of safety spring automatically.
Sliding sleeve in the utility model can cooperate the realization radial location by peripheral radially-protruding positioning plate more than 3 or 3 with body cavity, realize its axial restraint by withstanding in valve rod on the valve port, the sliding sleeve stage clip and base plate acting in conjunction.
The utility model compared with prior art has many advantages: it is efficient and convenient that 1. pressure governor is installed, the utility model has changed the left-hand thread connecting mode traditional with pressure governor, use the lock catch type connecting mode instead, as long as matching used fast-assembling pressure governor is withheld in the valve body upper end, operation not only fast but also light, and open cylinder valve is by the knob on the operation fast-assembling pressure governor, depress push rod in the cylinder valve by the thimble on the pressure governor, sealing gasket disengaging valve port is realized, therefore the shortcoming of having avoided the prior art rotary valve rod to waste time and energy is extremely easy to use; 2. do not have friction between sealing gasket on the valve rod and the valve port, sealing gasket can not leak gas because of wearing and tearing, so cylinder valve uses reliably, the life-span is long; 3. safe and reliable, lose heart owing to be provided with safety valve, make the LP gas cylinder that is full of gas in transportation or using process, can avoid crossing high reason and cause the steel cylinder blast by the gas of under certain pressure, releasing automatically because of vibration, ambient temperature.
Below in conjunction with accompanying drawing the utility model is described in further detail.
