Description
Technical field
The utility model relates to a kind of ball valve, particularly a kind of novel external control seal ball-valve.
Background technique
Since China's reform and opening-up, national economy rapid growth, scientific and technical innovation, autonomous innovation has become the main flow of domestic industry development.China's industry is just step by step to the future development of intensive style, energy-saving and emission-reduction, low-carbon (LC).The sealing of common Fixed ball valve is divided into DBB (two damming and pressure release) and DIB (two isolation and pressure release) structure conventionally, DBB structure is the most general a kind of valve seal form, DIB structure is divided into two kinds of different seal form, one is DIB-1, the valve seat that is valve two ends is Bidirectional seal structure, another kind is DIB-2, and one end valve seat of valve is Bidirectional seal structure, and the other end valve seat is one-way sealing structure.DBB and DIB type product are widely used in the pipeline of the every profession and trades such as electric power, petrochemical industry, metallurgy, ocean, oil, natural gas, pharmacy, not yet occur but meet above-mentioned three kinds of ball valves that seal demands simultaneously.The technician of R&D institution and enterprise is constantly exploring, is studying, and wishes to develop a kind of ball valve of superior performance, although make some progress, still exists the technical barrier not yet overcoming in practice.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, and a kind of novel external control seal ball-valve is provided, and valve seat, for integral type designs, adopts external control unit to control, easy to install, increase the service life, and good sealing effect.
The utility model solves the technological scheme that its technical problem adopts: contain connecting body, connecting plate, valve rod, valve body, nut, introduction valve, sealing control unit, valve component, spheroid, the runner of valve body is cylindrical shape, its middle part is cavity, is provided with spheroid in cavity, and valve body central authorities are provided with valve rod, valve rod is connected with spheroid through connecting plate, valve body two ends are provided with connecting body, and connecting body is connected with valve body by screw bolt and nut, between connecting body and spheroid, are provided with valve component, valve body two ends and connecting body joint are respectively provided with a sealing control unit, and described sealing control unit contains manual ball valve, pressure gauge, accumulator, annex pipeline, manual ball valve, pressure gauge, accumulator links into an integrated entity by annex pipeline respectively, and is connected with valve body, and described valve component contains fire-proof packing, sealing seat, spring, O type circle, valve seat supporting base, valve seat supporting base and spheroid joint place be sealing surface, described valve seat supporting base approaches on the end face of spheroid side and axially offers closure gasket groove, in closure gasket groove, be provided with sealing seat, valve seat supporting base forms two joint shoulders away from spheroid one side, and first segment shoulder is radially offered groove, in groove, be provided with fire-proof packing, second section shoulder is radially offered groove, is provided with O type circle in groove, and the side elevation of first segment shoulder is provided with spring.
The utility model solves the know-why that its technical problem adopts: ball valve, mainly for open and close pipeline and equipment medium, is to use with the spheroid of circular channel to do open-shut device, and spheroid rotates 90 ° with valve rod, realizes the keying of valve.The open-shut device of ball valve is a porose spheroid, and this spheroid rotates around the axis perpendicular to passage, thereby reaches the object that opens and closes passage.The utility model external control seal ball-valve can be realized DBB and DIB-1, tri-kinds of different sealing functions of DIB-2.
The realization of DBB function: when spheroid is during in enable possition, will keep being not less than the pressure (being generally 0.5～0.7MPa) of spring in sealing control unit, valve also can be realized lumen pressure release and discharge function in the time of standard-sized sheet like this.In the time that spheroid is in the closed position, in sealing control unit, the pressure (but the highest rated working pressure that is no more than 1.2 times) of upstream line will be kept being not less than, valve can be realized good two way sealed in the time of contract fully position like this, also can realize lumen pressure release and discharge function simultaneously.In addition, no matter valve is in standard-sized sheet or complete shut-down position, if when valve pocket pressure reaches 1.33 times of valve rated pressure, now both sides valve seat, by under the driving of pressure, departs from sphere, to reach the object of automatic inner pressure release.
The realization of DIB-1 function: when ball body of valve is in opening or when closed position, in sealing control unit, will keep being not less than the pressure (but the highest rated working pressure that is no more than 1.2 times) of upstream line, valve all can be realized lumen pressure release and discharge function in the time of standard-sized sheet or complete shut-down position like this.In the time that ball body of valve is in the closed position, in sealing control unit, the pressure (but the highest rated working pressure that is no more than 1.2 times) of upstream line will be kept being not less than, valve can be realized good two way sealed in the time of contract fully position like this, also can realize lumen pressure release and discharge function simultaneously.If when valve pocket pressure reaches 1.33 times of valve rated pressure, upstream and downstream valve seat is subject to respectively the control (being arranged on after manual ball valve) of external pressure relay system, automatically the system pressure of upstream control unit is down to below 0.7MPa, the system pressure of downstream control unit and valve pocket internal pressure are consistent simultaneously, upstream valve seat is automatic inner pressure release like this, and downstream valve seat will continue to keep sealing.
The realization of DIB-2 function: when spheroid is in opening or when closed position, in sealing control unit, will keep being not less than the pressure (but the highest rated working pressure that is no more than 1.2 times) of upstream line, valve all can be realized lumen pressure release and discharge function in the time of standard-sized sheet or complete shut-down position like this.In the time that ball body of valve is in the closed position, in sealing control unit, the pressure (but the highest rated working pressure that is no more than 1.2 times) of upstream line will be kept being not less than, valve can be realized good two way sealed in the time of contract fully position like this, also can realize lumen pressure release and discharge function simultaneously; If when valve pocket pressure reaches 1.33 times of valve rated pressure, upstream and downstream valve seat is subject to respectively the control (being arranged on after manual ball valve) of external pressure relay system, automatically the system pressure of upstream and downstream control unit is kept to consistent with valve pocket internal pressure, upstream and downstream valve seat just continues to keep sealing like this, and both sides valve seat has all been realized two way sealed.
The beneficial effects of the utility model are: a kind of novel external control seal ball-valve, and valve seat, for integral type designs, adopts external control unit to control, easy to install, increase the service life, can realize tri-kinds of sealing functions of DBB, DIB-1 and DIB-2, good sealing effect simultaneously.
