Second threaded tube forms connection；The connecting screwed tube inner ring is provided with the internal screw thread with the cooperation of the second threaded tube, described
Connecting screwed tube outer ring is provided with the external screw thread with valve body cooperation.
The formation of the upper pressure bolt and valve body is threadedly engaged, and the valve rod includes upper cylinder, middle chuck, lower fastening axle, it is described on
Cylinder passes through upper pressure bolt, and the upper pressure bolt resists middle chuck, is equipped with spring, the lower fastening axle between the middle chuck and core
It is affixed by spring and core activity.
Bolt is pressed in back-out, under the action of the spring, valve rod detaches core.Rotary valve rod at this time, core will not be with valve rods
Rotation.
Press bolt in precession, valve rod compressed spring, valve rod is affixed with core.Rotary valve rod at this time, core can be rotated with valve rod.
The sealing ring forms sealing cooperation, the support column setting along the both ends of valve body extending direction and core in core
In valve body lower portion and core is supported, the lower top cover is fixed on valve body lower portion, the lower top cover limitation branch by the second bolt group
Dagger falls off.
The safety-type straight-through valve of the utility model can be controlled the affixed and disengagement of valve rod and core by upper pressure bolt, be avoided
Valve rod is surprisingly revolved, and guarantees the safety of ball valve work.Pressure is bolted to valve rod under the action of the spring in back-out, detaches core.
Rotary valve rod at this time, core will not be rotated with valve rod.Press bolt in precession, valve rod compressed spring, valve rod is affixed with core.It revolves at this time
Rotating valve rod, core can be rotated with valve rod.
Optionally, the lower fastening axle is the prominent axis of hexagon.
Optionally, the spring is helical spring.
