Abstract

The utility model discloses a hydraulic valve for a lighter, which comprises an adjustable valve body, a valve rod assembly, and a valve sleeve. The valve rod assembly penetrates through an inner hole of the adjustable valve body, the bottom part of an inner hole on the intermediate section is provided with a convex platform, and the lower end of the outside is sheathed in a valve sleeve of a sealing rubber ring; the valve sleeve is pressed between the adjustable valve body and the valve rod assembly. The main technical feature is that the tail end of a valve rod body is a base plane surface, a guide part is provided with a two-way liquid flowing hole communicated with a central hole, the platform on the bottom part of the inner hole on the intermediate section of the valve sleeve is enlarged and is lifted up, and a liquid flowing passage on the lower end is lengthened, and the section close to the platform is shortened. The utility model has the advantages that the copper material can be saved, the gas discharge and the liquid charge are quick, the sealing performance is good, the immediate sealing effect is better, and the service life is long.

Description

Lighter hydraulic pressure valve

The utility model relates to a kind of improved hydraulic valve, particularly a kind of lighter hydraulic pressure valve.

Existing lighter hydraulic pressure valve, comprise adjustable valve body, valve rod assembly and valve pocket, valve-rod body center in the valve rod assembly is porose, head is a conical nozzle, be fork successively then, guiding, pedestal and seat tail cylinder each several part, the marshall springs boss is arranged on the pedestal, on the seat tail behind the pedestal liquid flow hole and the unidirectional UNICOM of valve-rod body centre bore are arranged, the valve pocket that in the patent No. is 96237604.3 utility model patent, is called as a part, raised platform is arranged at bottom, endoporus stage casing, outer upper ends and adjustable valve body endoporus match, the lower end is the O-ring seal load segment and forms the conical sloping platform of the trim ring that carries out the transition to big end, from the valve-rod body head nozzle spring of packing into, embed O-ring seal again, fill in the valve rod assembly of sealing plug at the tail end centre bore, the endoporus that has the adjustable valve body of regulating screw thread from the outside passes, valve pocket is pressed between adjustable valve body and the valve rod assembly then, through valve pocket is carried out improved this product, be characterized in that the valve pocket in the product can an injection molded, save the part copper material, but, prevent that energy-conservation grand consumption problems such as leak of liquid are still people's Focal Point of Common Attention.

The purpose of this utility model is that a kind of lighter hydraulic pressure valve will be provided, and it is not only saved copper material but also can seal better, also has process industrial art performance and long service life preferably.

The purpose of this utility model is achieved in that

It comprises that the center is porose, head is a conical nozzle, then be the fork guiding successively, the valve-rod body of pedestal cylinder each several part, from the valve-rod body head nozzle spring of packing into, embed O-ring seal again, fill in the valve rod assembly of sealing plug at the tail end centre bore, the endoporus that has the adjustable valve body of regulating screw thread from the outside passes, raised platform is arranged at bottom, endoporus stage casing, outer upper ends and adjustable valve body endoporus match, outside lower end is the O-ring seal load segment and forms the valve pocket of nature O-ring seal in conjunction with platform, and valve pocket is pressed between adjustable valve body and the valve rod assembly, and described valve-rod body end is a base plane, upwards forms pedestal marshall springs boss, and liquid flow hole moved to the targeting part of valve-rod body, and become two-way and valve-rod body centre bore UNICOM;

Platform corresponding increase of described valve pocket endoporus stage casing base projections with the variation of valve rod assembly base plane, on carry, the fluid course of lower end also extends, this fluid course is near the inner hole platform section, its diameter diminishes.

The good effect that the utility model is compared with prior art produced:

1, the end of the valve-rod body after the improvement is a base plane, does not have a portion, so saving copper material quantity is big;

2, two-way liquid flow hole can be discharged air smoothly and be poured into liquid fast;

3, with carry on the sealed faying face, the lengthening of increase and fluid course, diminish, make its sealing property better, instant sealing effectiveness is better, energy-saving effect is more obvious;

4, the reinforcement of valve pocket wall thickness has prolonged service life of parts, and processing performance is also better.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the utility model cutaway view.

Fig. 2 is a valve-rod body cutaway view among Fig. 1.

Fig. 3 is a valve pocket profile among Fig. 1.

Making further detail below with reference to accompanying drawing describes: referring to accompanying drawing, center porose 1, head is a conical nozzle 2, is fork 3 successively then, guiding 4, end is the valve-rod body 6 of the cylinder each several part of pedestal 5, the end plane 20 of its pedestal is the faying face of liquid sealing, and what upwards formed by the plane is pedestal marshall springs boss 21, at boss 21 nearby, on the guiding 4 liquid flow hole 23 is arranged, 23 one-tenth of liquid flow holes are two-way by valve-rod body 6 and centre bore 1 UNICOM; After spring 7 pack into from valve-rod body 6 head nozzles 2, embed O-ring seal 8 again, fill in the valve rod assembly 11 of sealing plug 10 at tail end centre bore 1, the endoporus 14 that has the adjustable valve body 13 of regulating screw thread 12 from the outside passes, the bossed platform 16 in valve pocket 19 stage casing endoporus 15 bottoms, it is the faying face of liquid sealing, from platform 16 is downwards fluid course 24, fluid course 24 is in close platform section, its passage 25 diameters diminish, valve pocket 19 outer upper ends 9 match with adjustable valve body 13 endoporus 14, lower end 17 is for O-ring seal 18 load segments and form a natural O-ring seal in conjunction with platform 22, then valve pocket 19 is pressed between adjustable valve body 13 and the valve rod assembly 11, each parts of lighter hydraulic pressure valve just make up assembling and finish.

Comprehensive accompanying drawing, valve rod assembly 11 behind the assembly in the hydraulic valve has been clipped less than the seat portion of susceptor diameter because of valve-rod body 6 and has been carried on the whole, the platform 16 of valve pocket 19 stage casing endoporus 15 base projections is with the increase of valve rod assembly 11 terminal base plane 20, its platform 16 corresponding increases, on carry, lower end passage 25 also extends, and diminishes near passage 25 diameters of platform section 16, so, the liquid sealed faying face strengthens, and sealing effectiveness is better, and instant sealing effectiveness is better; Because of the valve-rod body 6 of valve rod assembly is provided with two-way liquid flow hole 23, have and irritate the liquid and the outside double action of deaeration inward, it is rapid to make in the lighter fluid reservoir dress irritate liquid, and can gets more.
