The utility model discloses a three-piece butt-welding ball valve, which comprises a valve body. The two sides of the valve body are provided with connecting flanges, the inner part of the valve body is provided with a ball body, the top part of the ball body is provided with a valve stem, the top part of the valve stem is provided with a handle, the handle is provided with a tightening bolt, the handle is penetrated with a locking plate, and the top part of the ball body is provided with a filler. A fixed seat is arranged on one side of the valve body. The utility model pushes the operation plate through setting the limit plate and the operation plate, and the operation plate pushes the limit plate to move in the empty slot and compresses the spring. At this time, the handle can be rotated so that the lock piece on the handle rotates into the recessed interior of the operation plate, and continues to rotate the handle, the handle pushes the lock plate to rotate, and the lock plate pushes the operation plate to rotate relative to the limit part in the limit slot, when operating. When the plate is separated from the limit plate, the spring pushes the limit plate, and the limit plate places the locking plate in the clamp, which can prevent the handle from being touched and rotated, and is conducive to improving the safety of use.
【技术实现步骤摘要】
一种三片式活接对焊球阀
本技术涉及阀门
,特别涉及一种三片式活接对焊球阀。
技术介绍
球阀亦可用于流体的调节与控制,其中硬密封V型球阀其V型球芯与堆焊硬质合金的金属阀座之间具有很强的剪切力,特别适用于含纤维、微小固体颗料等的介质。而多通球阀在管道上不仅可灵活控制介质的合流、分流、及流向的切换,同时也可关闭任一通道而使另外两个通道相连。现有的三片式活接对焊球阀在将手柄扳回到原位后,没有对其限位的措施,在触碰到手柄时,容易造成阀门开启,亟待改进。因此,专利技术一种三片式活接对焊球阀来解决上述问题很有必要。
技术实现思路
本技术的目的在于提供一种三片式活接对焊球阀,通过限位板和操作板,操作板能够推动限位板压缩弹簧,使锁片进入卡口内,限位板将锁片限位在卡口内,以解决上述
