Fig. 1 is structural representation of the present utility model.
Fig. 2 is the linkage structure schematic diagram of the utility model and outer tube before work.
Fig. 3 is the linkage structure schematic diagram of the utility model and outer tube in work.
Embodiment
With reference to figure 1 – Fig. 3, the utility model is described further.
A kind of gas valve, comprise gas valve body, establish the valve body 1 of cavity in gas valve body comprises, valve body 1 has been threaded connection adapter 2, be provided with the start-stop device for making cavity be communicated with adapter 2 or block in described gas valve body, described gas valve body is provided with location locking mechanism.
Further, described start-stop device comprises the first spring 31 and to be slidably connected with gas valve body and conflict with the inside of valve body 1 and be connected in one end of spool 32, first spring 31 of adaptation, and the other end is conflicted with spool 32 and is connected.
Further, described location locking mechanism comprises at least one steel ball 41, is set in the second spring 42 on gas valve body and annular knurl sleeve pipe 43 successively, one end of second spring 42 is connected with valve body 1, the other end is connected with annular knurl sleeve pipe 43, be provided with the cavity volume 21 for accommodating steel ball 41 in described adapter 2, described annular knurl sleeve pipe 43 is provided with the positioning ring block 431 for locking ball 41.
Before work, the first spring 31 is in compressive state, and the annular protrusion 325 on spool 32 is stuck on gas valve body, and play the effect limiting spool 32, the second spring 42 is in compressive state, and the positioning ring block 431 on annular knurl sleeve pipe 43 is just blocked by steel ball 41;
During work, outer tube 6 stretches in adapter 2, conflict and extrude spool 32, make the intercommunicating pore 324 on spool 32 and cavity connects, and then cavity is communicated with adapter 2, coal gas just can enter outer tube 6 from cavity, the number of steel ball 41 is 4, outer tube 6 is provided with 4 grooves with 4 steel ball 41 adaptations, and when outer tube 6 extrudes spool 32 and extend into a certain degree, so steel ball 41 falls into groove, now, positioning ring block 431 departs from steel ball 41, and under the elastic force effect of the second spring 42, positioning ring block 431 moves toward the direction of steel ball 41 and blocks steel ball 41;
After work, relative to gas valve body to annular knurl sleeve pipe 43 firmly, and then extract outer tube 6, spool 32 resets under the elastic force effect of the first spring 31, and now, positioning ring block 431 is blocked by steel ball 41 again, the state before resuming work;
Wherein the number of steel ball 41 can be 1,2,3,4, even more, in order to the locating effect of the structural strength and steel ball 41 of considering the adapter after perforate 2, the quantity of steel ball 41 is set to 4, and annular array is in adapter 2, outer tube 6 is provided with 4 grooves with 4 steel ball 41 adaptations.
When outer tube 6 inserts, and extruding spool 32, cavity is just made to be communicated with adapter 2, so just achieve opening state, and utilize location locking mechanism to fix outer tube 6, when extracting outer tube 6, first spring 31 drives spool 32 to reset, just achieve closed condition, this gas valve is opened or quick closedown fast, the phenomenon generation that effective Accident prevention occurs and do not have timely throttle down and then cause accident to worsen.
Further, described valve body 1 and adapter 2 are provided with O type circle 51 and a 2nd O type circle 52 respectively with the place of being slidably connected of spool 32.
Utilize spool 32 slide realize open or close; therefore; be provided with O type circle 51 and a 2nd O type circle 52 respectively with the place of being slidably connected of spool 32 at valve body 1 and adapter 2, play the effect of duplicate protection, the phenomenon preventing coal gas from revealing from spool 32 and the joint of valve body 1 occurs.
Further, described spool 32 comprises the cylindrical shell 321 that one end is provided with sealing cover 322, sealing cover 322 is provided with the column-shaped projection 323 of restriction first spring 31 position, first spring 31 is volute spring, column-shaped projection 323 is the little head ends in order to fixing volute spring, the sidewall of cylindrical shell 321 is provided with intercommunicating pore 324, center as intercommunicating pore 324 is larger relative to the length of cylindrical shell 321 to the distance of sealing cover 322, outer tube 6 will be caused to need to stretch into adapter 2 inside darker, the material manufacturing this gas valve body is longer, cost is higher, center as intercommunicating pore 324 is less relative to the length of cylindrical shell 321 to the distance of sealing cover 322, the location of locking positioning mechanism can be made again not firm, locating effect is poor, therefore, in conjunction with more than, the center of through hole is set to 1:3 to the distance of sealing cover 322 and the lenth ratio of cylindrical shell 321.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, those skilled in the art carries out common change and replaces should being included in protection domain of the present utility model within the scope of technical solutions of the utility model.
