Wherein, elasticity conflict device includes the installation cavity being opened on installation gap inwall, is located at compressing spring and compressing steel ball in installation cavity, conflicts with compressing spring in the one end that compresses steel ball, and the other end and valve seat are conflicted.
Adopt technique scheme, the installation gap that can install for valve seat is set by the place, one end in jointing extends to valve body, the valve seat of spheroid control gear can be directly installed on jointing, impel the internal diameter adaptation of endoporus and the jointing of valve seat, the endoporus adaptation of the internal diameter and the valve seat that make jointing is set like this, pressure in valve body is balanced, and makes the conveying of combustion gas more stable; The setting of elasticity conflict device makes valve seat have all the time conflict power towards spheroid, and the sealing between valve seat and spheroid is protected, and sealing is improved.
The utility model is further set to: between two spheroid control gear, be provided with pressure relief device, this pressure relief device includes valve body that offer and through hole extraneous conducting and be installed on this through hole and impel this through hole sealing or the stop valve with extraneous conducting between two spheroid control gear.
Adopt technique scheme, setting can make two spheroid control gear all implement to close the rear enforcement of the part between the two spheroid control gear pressure release to valve body like this, with the pressure of this balance valve inner, makes the conveying of combustion gas more stable and smooth and easy.
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment's structural representation;
Fig. 2 is the I portion enlarged diagram of Fig. 1.
Embodiment
As Fig. 1, a kind of gauge ball valve shown in Fig. 2, include valve body 1 and be located at side by side the spheroid control gear 2 on valve body 1, spheroid control gear 2 includes the spheroid 21 of being located in valve body 1, one end extends in valve body 1 and is connected with spheroid 21, the other end extends the valve rod 22 outside valve body 1 and starts the Joystick 23 that valve rod 22 rotates, in valve body 1, be provided with the valve seat 24 sealing with spheroid 21, pipeline connecting end outside axial one end of valve body 1, the other end is outside output connecting end, its outside output connecting end place is provided with the jointing 3 being connected with valve body 1, the place, one end that jointing 3 extends in valve body 1 is provided with the installation gap 31 of installing for valve seat 24, valve seat 24 is installed in this installation gap 31, and the internal diameter adaptation of the endoporus of valve seat 24 and jointing 3, on the side face of jointing 3 outside valve body 1, be arranged with adpting flange 4, between installation gap 31 and valve seat 24, be provided with elasticity conflict device 5.In such scheme, the installation gap 31 that can install for valve seat 24 is set by the place, one end in jointing 3 extends to valve body 1, the valve seat 24 of spheroid control gear 2 can be directly installed on jointing 3, impel the internal diameter adaptation of endoporus and the jointing 3 of valve seat 24, the endoporus adaptation of the internal diameter and the valve seat 24 that make jointing 3 is set like this, pressure in valve body 1 is balanced, and makes the conveying of combustion gas more stable; The setting of elasticity conflict device 5 makes valve seat 24 have all the time conflict power towards spheroid 21, and the sealing between valve seat 24 and spheroid 21 is protected, and sealing is improved; The setting of adpting flange 4 can facilitate installation and the dismounting between valve body and joint outer part.
