Adopt above-mentioned further setting; Described valve gap and base removably connect; Described valve seat supporting base and valve seat are that valve seat can directly upwards take out from valve pocket for the separable cooperation that makes progress; Like this can the on-line maintenance valve, need the medium flow channel of valve, the pipeline that the medium flow pass is connected just not taken apart and can safeguard inner components; The spring, the spring seat that are provided with can improve sealing effect; Described seal ring can prevent that medium from getting into the service behaviour that spring seat is interior, influence spring.
Further being provided with again of the utility model: described valve seat and ball core sealing part are provided with annular scraping blade.
Adopt above-mentioned further setting again, when the conveying solid substance granule medium, can adhere to some solid particles on the ball core, the annular scraping blade of setting can scrape the solid particle of ball core, reaches the purpose of cleaning ball core.
The further setting of the utility model: described valve pocket bottom is provided with supporting element, and described ball core lower end is provided with the supported hole that supplies described supporting element to insert, described supported hole and the coaxial setting of axis hole, and described supporting element cooperates with the rotation of ball core.
Adopt above-mentioned further setting, described supporting element can support well, the place kick core, makes the ball core successfully to rotate.
