Further, described elastic card comprises outer ring, described outer ring is evenly equipped with some plectrums, described plectrum is crossing with outer ring center line, and formed sharp angle is 40 degree of-50 degree, the joint of outer ring and each plectrum is provided with arc plate, and described arc plate comprises the first cambered surface and the second cambered surface, and the radius of curvature of the first cambered surface is greater than the radius of curvature of the second cambered surface.
Further, described low pressure valve body is provided with the chamfering of ring-type.
Further, described low pressure valve body is provided with the first hole, and described lock nut is provided with the second hole, and the internal diameter in the first hole is all identical with the internal diameter in the second hole.
Further, described plectrum comprises A point, each A point is positioned at same circle circumferentially, and this diameter of a circle is less than the internal diameter in the first hole.
Contrast the deficiencies in the prior art, the beneficial effect that the technological scheme that the utility model provides is brought: by above design, externally connected pipe is utilized to be connected with low pressure valve body, and externally connected pipe is provided with ring-type limiting stopper, ring-type limiting stopper external diameter is identical with the first hole internal diameter, therefore, externally connected pipe is directly backed down plectrum and inserts in low pressure valve body, plectrum is made to block ring-type limiting stopper, firm when making low pressure valve body and externally connected pipe in succession, and then make low pressure valve body and externally connected pipe also be not easy when bearing internal liquid or gas to burst; Meanwhile, externally connected pipe does not need when being connected with this valve by any instrument, without any need for connection fastening piece, just can reach firm connection, accelerate connection speed, improve working efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the cross-sectional schematic of elastic card.
Fig. 3 is the front elevational schematic of elastic card.
Fig. 4 is the G portion structure for amplifying schematic diagram of Fig. 2.
Embodiment
With reference to Fig. 1-Fig. 4, the utility model is described further.
One connects low pressure valve soon, comprise low pressure valve body 1, described low pressure valve body 1 is provided with decompression hole, decompression hole comprises the first endoporus 21, second endoporus 22 and the 3rd endoporus 23 that are communicated with successively, the internal diameter of the internal diameter of the first endoporus 21, the internal diameter of the second endoporus 22 and the 3rd endoporus 23 reduces successively, the aperture place of decompression hole is provided with quick access device, and described quick access device comprises the lock nut 11 be connected on low pressure valve body 1, is provided with elastic card 3 between low pressure valve body 1 and lock nut 11.
Further, described elastic card 3 comprises outer ring 31, described outer ring 31 is evenly equipped with some plectrums 32, described plectrum 32 is crossing with outer ring 31 center line, and formed sharp angle is 40 degree of-50 degree, outer ring 31 is provided with arc plate 33 with the joint of each plectrum 32, and the radius of curvature that described arc plate 33 comprises the first cambered surface 331 and the second cambered surface 332, first cambered surface 331 is greater than the radius of curvature of the second cambered surface 332.
Further, described low pressure valve body 1 is provided with the chamfering 111 of ring-type.
Further, described low pressure valve body 1 is provided with the first hole 101, and the internal diameter that described lock nut 11 is provided with the second hole 101, hole 102, first is all identical with the internal diameter in the second hole 102.
Further, described plectrum 32 comprises A point 321, each A point 321 is positioned at same circle circumferentially, and this diameter of a circle is less than the internal diameter in the first hole 101.
Outer ring 31 is provided with arc plate 33 with the joint of each plectrum 32, described arc plate 33 comprises the first cambered surface 331 and the second cambered surface 332, the radius of curvature of the first cambered surface 331 is greater than the radius of curvature of the second cambered surface 332, arc plate 33 is made to become thicker, structural strength is large, effectively prevent plectrum 32 from irreversible deformation occurring and cause the irreducible phenomenon of plectrum 32 to occur, effectively extending the working life of elastic card 3.
By above design, externally connected pipe is utilized to be connected with low pressure valve body 1, and externally connected pipe is provided with ring-type limiting stopper, ring-type limiting stopper external diameter is identical with the first hole 101 internal diameter, therefore, externally connected pipe is directly backed down plectrum 32 and inserts in low pressure valve body 1, makes plectrum 32 block ring-type limiting stopper, firm when making low pressure valve body 1 and externally connected pipe in succession, and then make low pressure valve body 1 and externally connected pipe also be not easy when bearing internal liquid or gas to burst; Meanwhile, externally connected pipe does not need when being connected with this valve by any instrument, without any need for connection fastening piece, just can reach firm connection, accelerate connection speed, improve working efficiency.
And when dismantling, because lock nut 11 and low pressure valve body 1 are threaded connection, directly turn on lock nut 11, realize dismounting.
Because plectrum 32 comprising A point 321, each A point 321 is positioned at same circle circumferentially, and this diameter of a circle is less than the internal diameter in the first hole 101, and therefore, each plectrum 32 can be good at the ring-type limiting stopper blocking externally connected pipe, makes connection more firm.
And number outer ring 31 being evenly equipped with plectrum 32 is 16, therefore, two plectrums 32 of arbitrary neighborhood leave space again, such design make externally connected pipe easily back down plectrum 32 and and then in low pressure valve body 1, easy-to-operat, improves working efficiency.
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.
