Abstract
The utility model discloses a kind of hard seal ball valve, comprise valve body, path valve plug, valve ball and spool, described body base is provided with flow path, path valve plug is arranged at path one end, and valve ball is arranged in valve body by path valve plug one end, and spool is arranged at valve body top, and be fixedly connected with valve ball bottom spool, also comprise import valve seat, outlet valve seat, disc spring, regulating ring and back-up ring, described import valve seat, outlet valve seat are arranged at valve ball two ends respectively, with path UNICOM; Described disc spring, regulating ring and back-up ring are all arranged on the path of valve ball side, and disc spring is arranged at inside regulating ring, back-up ring is arranged at outside regulating ring; The parts with telescopicing performance are added in original valve ball path both sides, effectively can alleviate valve ball expansion at high temperature under high pressure, the illusive possibility of the equipment use caused, effectively can increase the working life of equipment and reduce maintenance and the replacement frequency of parts.
Description
Technical field
The utility model relates to a kind of ball valve, particularly relates to a kind of hard seal ball valve.
Background technique
Metal hard-sealing ball valve is applied to worst hot case usually, and material thermal expansion is at high temperature the problem that metal hard-sealing ball valve design must be considered.Sealing between the valve seat of high-temperature metal hard-sealed ball valve and valve body adopts Expanded graphite usually, the materials such as Expanded graphite at high temperature can produce volumetric expansion, if structural design does not consider material expansion compensation at high temperature, valve at high temperature will inevitably be stuck and akinesia because of the expansion of material.
Model utility content
For above-mentioned produced problem, the utility model provides simple, reasonable in design, easy for installation, the effective solution ball valve body of a kind of structure and amasss to expand and cause the phenomenon of equipment use inconvenience.
A kind of hard seal ball valve, comprise valve body, path valve plug, valve ball and spool, described body base is provided with flow path, path valve plug is arranged at path one end, and valve ball is arranged in valve body by path valve plug one end, and spool is arranged at valve body top, and be fixedly connected with valve ball bottom spool, also comprise import valve seat, outlet valve seat, disc spring, regulating ring and back-up ring, described import valve seat, outlet valve seat are arranged at valve ball two ends respectively, with path UNICOM; Described disc spring, regulating ring and back-up ring are all arranged on the path of valve ball side, and disc spring is arranged at inside regulating ring, back-up ring is arranged at outside regulating ring.
Compared with prior art, the beneficial effect had is: add the parts with telescopicing performance in original valve ball path both sides, effectively can alleviate valve ball expansion at high temperature under high pressure, the illusive possibility of the equipment use caused, effectively can increase the working life of equipment and reduce maintenance and the replacement frequency of parts.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Be illustrated in figure 1 a kind of embodiment of the utility model hard seal ball valve, at original valve body 1, path valve plug 2, on valve ball 3 and spool 6, flow path 10 is provided with bottom valve body 1, path valve plug 2 is arranged at flow path 10 one end, valve ball 3 is arranged in valve body 1 by path valve plug 2 one end, spool 6 is arranged at valve body 1 top, and be fixedly connected with valve ball 3 bottom spool 6, valve ball 3 both sides flow path 10 is also provided with import valve seat 4, outlet valve seat 5, disc spring 8, regulating ring 7 and back-up ring 9, import valve seat, outlet valve seat is arranged at two ends, valve ball left and right respectively, three and flow path form UNICOM, disc spring, regulating ring and back-up ring are all arranged on the path of valve ball path valve plug side, and disc spring is arranged at inside regulating ring, back-up ring is arranged at outside regulating ring, preferably employ the flexible part of disc spring as this programme in the present embodiment, be not precluded within this programme and use other can realize the flexible miscellaneous part of this programme.
