Embodiment
Further understand for making to have structure characteristic of the present utility model and effect of reaching and be familiar with, coordinate detailed description in order to preferred embodiment and accompanying drawing, be described as follows:
Fig. 1 to Fig. 3 gives an embodiment of the present utility model, in this embodiment, give a kind of rock gas charging valve of novel sealing structure, comprise valve body 1 and the valve gap 2 being located at valve body 1 enterprising gas port 11 place, this valve gap 2 and valve body 1 are provided with the screw thread matched, namely this valve gap 2 is fixedly connected with the mode of valve body 1 screw-thread fit, simultaneously, seal washer 5 is provided with between this valve gap 2 and valve body 1, ensure the sealability between valve gap 2 and valve body 1 thus, prevent combustion gas from revealing from the joint of valve gap 2 and valve body 1.In addition, this valve gap 2 is provided with the gas passage 21 be connected with suction port 11, when after access inflation plug 6 on valve gap 2, combustion gas just can enter into the suction port 11 on valve body 1 along with the gas passage 21 on valve gap 2, and enter into gas holder, to realize to gas holder aerating by the air outlet outflow on valve body 1.
Simultaneously, in order to the combustion gas ensureing in the utility model rock gas charging valve there will not be the situation of refluence, nonreturn valve core 3 is provided with in suction port 11 on this valve body 1, one end that this nonreturn valve core 3 is adjacent with this gas passage 21 is provided with O RunddichtringO 4, the horizontal seal face 22 corresponding with O RunddichtringO 4 is provided with in this gas passage 21, thus realize upon inflation, as shown in Figure 3, nonreturn valve core 3 advances by high-pressure gas in gas passage 11 backward, O RunddichtringO 4 now on nonreturn valve core 3 is separated with the horizontal seal face 22 in gas passage 21, high-pressure gas can enter into suction port 11 from gas passage 21 smoothly, and by the air outlet on valve body 1 to gas holder aerating, after inflation, as shown in Figure 2, the O RunddichtringO 4 on this nonreturn valve core 3 can tightly be fitted in gas passage 21 on horizontal seal face 22 under the pressure of the inner combustion gas of valve body 1, namely prevents the refluence of combustion gas to realize damming.In addition, in the utility model, the plane sealing in this O RunddichtringO 4 and horizontal seal face 22 coordinates, coordinate compared to traditional conical surface seal, stressed meeting wherein on O RunddichtringO 4 is more even, i.e. the more difficult wearing and tearing of O RunddichtringO 4, adopts plane sealing to coordinate simultaneously, require also greatly to reduce to the installation precision of nonreturn valve core 3, namely this plane sealing cooperation can reach and better seal effect of damming.Therefore the utility model has the low and practical advantage of long service life, cost of production.
More particularly, in the present embodiment, the inserted link 32 that this nonreturn valve core 3 comprises pedestal 31 and is located on pedestal 31, this pedestal 31 is provided with the jack 33 corresponding with inserted link 32, this inserted link 32 is inserted in this jack 33 in an interference fit, simultaneously, this inserted link 32 is provided with the mounting groove 321 corresponding with O RunddichtringO 4, this pedestal 31 is provided with locating slot 311 corresponding with O RunddichtringO 4, therefore the utility model is in assembly process, first O RunddichtringO 4 is set in the mounting groove 321 on inserted link 32, again inserted link 32 is inserted in the jack 33 on pedestal 31, after inserted link 32 inserts completely, now just O RunddichtringO 4 is squeezed in the locating slot 311 on pedestal 31, thus the cooperation that can realize by locating slot 311 on mounting groove 321 on inserted link 32 and pedestal 31, O type is allowed to seal 4 circles firmly, be fixed on reliably on nonreturn valve core 3.In addition, inserted link 32 is except fixing O RunddichtringO 4, and it also serves the effect of guiding, namely ensures that the motion of nonreturn valve core 3 is more stable.
Simultaneously, in the present embodiment, groove 34 is provided with away from the one end in horizontal seal face 22 at this pedestal 31, the wall of this groove 34 is provided with vent 35, thus when realizing inflation, the combustion gas entering into the enterprising gas port 11 of valve body 1 can fast and enter into the blast tube in valve body 1 by vent 35 smoothly; And after inflation, the pressure that high-pressure gas in valve body 1 in blast tube can give one, the bottom of groove 34 huge, thus whole nonreturn valve core 3 is pushed ahead, namely to realize on nonreturn valve core 3 plane sealing between O RunddichtringO 4 with gas passage 21 horizontal seal face 22 to coordinate, occur flowing backwards to prevent the combustion gas in valve body 1.
More than show and describe basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; the just principle of the present utility model described in above-described embodiment and specification; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
