Abstract
The utility model discloses a cylinder valve with a self-closing quick-connecting device. The air outlet of a cylinder valve body is provided with a check valve, the check calve is quickly connected with the cylinder valve through a connector, and the connector is locked by a lock sleeve and a steel ball. The cylinder valve has the advantages that the installation is very convenient and quick, the problem that liquefied petroleum gas easily leaks when the liquefied petroleum gas is replaced can be solved by the check valve and a sealing ring, and the condition that when a cylinder is transported, stored and connected, the safety accidents is caused due to gas leakage can be avoided.
Description
Technical field
The utility model relates to the cylinder valve of liquefied petroleum ga steel cylinder.
Background technique
Domestic traditional liquefied petroleum gas cylinder valve air outlet is that open type is threaded at present, be LP gas cylinder by being threaded reduction valve and be connected with the liquefied petroleum gas (LPG) tool, liquefied petroleum in bottle is run out of air, when changing gas, reduction valve will be screwed out, the reduction valve precession be had the gas cylinder of gas again, the replacing process is loaded down with trivial details, complicated operation is installed the bad gas leak that very easily causes; In addition,,, do not have seal arrangement, very easily cause leakage, cause security incident because the air outlet is an open type in transportation, the storage of gas cylinder with when being connected.
The model utility content
The technical problems to be solved in the utility model provides a kind ofly can seal the air outlet automatically, and can connect cylinder valve fast, to reach convenient, fast, purpose of safety.
The technological scheme that adopts for solving the problems of the technologies described above: a kind of cylinder valve with self-closing Quick Connect Kit, include the valve body of cylinder valve, the connection-peg that is threaded in the check valve body on the valve body air outlet and pegs graft fast with check valve body, it is characterized in that: be provided with sealing gasket between the end of described check valve body and the valve body, described check valve body inner chamber front half part is provided with nonreturn valve core, nonreturn valve core is provided with the unidirectional valve pad that is one-way sealing with the sealed step of check valve body, be provided with the taper pressure spring between nonreturn valve core and the check valve body, described check valve body inner chamber latter half part and described connection-peg are set as form fit and peg graft, and be provided with the seal ring of a circle at least in order to the described connection-peg front end of sealing socket at the check valve body inner chamber, offer some through holes of along the circumferential direction evenly laying on the chamber wall of described check valve body, described through hole is outside reaming setting, taken up steel ball on the through hole, the outer outer wall of described check valve body is set with lock tube, along the circumferential direction be provided with on the lock tube inwall in order to compress the lug boss of steel ball, be installed with back-up ring on the outer wall of described check valve body outermost end in order to the block lock tube lug boss outside, be provided with pressure spring between lock tube lug boss inboard and the end, valve body air outlet, the corresponding described steel ball of described connection-peg position is provided with groove along the circumferential direction.
Adopt the beneficial effect that the utility model brought:, install very convenient, quick because the utility model adopts quick connection-peg to realize and being connected of the valve body of cylinder valve, and locks connection-peg by lock tube and steel ball.Solve the problem that in changing the liquefied petroleum gas (LPG) process, very easily causes liquefied petroleum gas leakage with one-way valve and seal ring, prevent transportation, storage and when being connected, because the security incident that gas leakage causes at gas cylinder.
Description of drawings
Fig. 1 is the structural representation that the utlity model has the cylinder valve of self-closing Quick Connect Kit.
Embodiment
As shown in Figure 1, a kind of cylinder valve, the connection-peg 3 that includes cylinder valve valve body 1, is threaded in the check valve body 2 on the valve body 1 and pegs graft fast with check valve body 2 with self-closing Quick Connect Kit.Be provided with sealing gasket 4 between the end of check valve body 2 and the cylinder valve valve body 1, check valve body 2 inner chamber front half parts are provided with nonreturn valve core 5, nonreturn valve core 5 is provided with the unidirectional valve pad 6 that is one-way sealing with the sealed step 201 of check valve body 2, is provided with taper pressure spring 7 between nonreturn valve core 5 and the check valve body 2.Check valve body 2 inner chamber latter half parts and connection-peg 3 are set as form fit and peg graft, and are provided with a circle patches joint 3 front ends in order to stuffing box gland seal ring 8 at least at check valve body 2 inner chambers.Offer some through holes 202 of along the circumferential direction evenly laying on the chamber wall of check valve body 2, through hole 202 is outside reaming setting, has taken up steel ball 10 on the through hole 202.The outer wall of check valve body 2 is set with lock tube 9, along the circumferential direction be provided with lug boss 901 on lock tube 9 inwalls in order to compress steel ball 10, be installed with back-up ring 11 on the outer wall of check valve body 2 outermost end, be provided with pressure spring 12 between lock tube 9 lug bosses, 901 inboards and the end, valve body 1 air outlet in order to block lock tube 9 lug bosses 901 outsides.Connection-peg 3 corresponding steel balls 10 positions are provided with groove 301 along the circumferential direction.
During grafting, the push-and-pull lock tube 9 inward, make lock tube 9 lug bosses 901 break away from steel ball 10 fully, and this moment, steel ball 10 can withdraw from outward, and connection-peg 3 is inserted in the check valve body 2.When connection-peg 3 does not back down nonreturn valve core 5 as yet, connection-peg 3 is finished sealing earlier with the seal ring of check valve body 2 inner chambers, when connection-peg 3 backs down nonreturn valve core 5, taper pressure spring 7 compressions of nonreturn valve core 5, unidirectional valve pad 6 is thrown off with the sealed step 201 of check valve body 2, one-way valve opens, at this moment steel ball 10 just in time faces toward the groove 301 of connection-peg 3, unclamp lock tube 9, pressure spring 12 promotes lock tube 9 and resets, the lug boss 901 of lock tube 9 is pressed on steel ball 10 on the groove 301 of connection-peg 3, so just connection-peg 3 is locked in the check valve body 2, finishes docking of connection-peg 3 and check valve body 2.
And withdraw from when pegging graft, be push-and-pull lock tube 9 inward equally, make lock tube 9 lug bosses 901 break away from steel ball 10 fully, this moment, steel ball 10 can withdraw from outward, and connection-peg 3 is pulled away check valve body 2, taper pressure spring 7 promotes nonreturn valve core 5 and resets, the sealed step 201 that makes unidirectional valve pad 6 and check valve body 2 is closing seam again, and closed check valve is after connection-peg 3 pulls away check valve body 2, lock tube 9 also resets again, finishes separating of connection-peg 3 and check valve body 2.In whole replacing liquefied petroleum gas (LPG) process, prevented the problem of liquefied petroleum gas leakage effectively.
