Description

一种基于压力平衡的一片式球阀A one-piece ball valve based on pressure balance

技术领域Technical field

本实用新型涉及阀门技术领域,尤其涉及一种基于压力平衡的一片式球阀。The utility model relates to the technical field of valves, in particular to a one-piece ball valve based on pressure balance.

背景技术Background technique

球阀,启闭件由阀杆带动,并绕球阀轴线作旋转运动的阀门。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。球阀在管路中主要用来做切断、分配和改变介质的流动方向,它只需要用旋转90度的操作和很小的转动力矩就能关闭严密。球阀最适宜做开关、切断阀使用。Ball valve, a valve whose opening and closing parts are driven by the valve stem and rotate around the axis of the ball valve. It can also be used for the regulation and control of fluids. The hard-sealed V-shaped ball valve has a strong shear force between the V-shaped ball core and the metal valve seat with hard alloy surfacing. It is especially suitable for materials containing fibers and tiny solid particles. etc. media. The multi-way ball valve can not only flexibly control the confluence, divergence, and flow direction switching of media on the pipeline, but can also close any channel and connect the other two channels. The ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. It only needs to rotate 90 degrees and a small rotational torque to close tightly. Ball valves are most suitable for use as switches and shut-off valves.

而现有的球阀密封圈是固定的,一次性使用,稍有磨损就会漏水,并且难以维修更换,从而导致整个球阀报废;目前的球阀在管内水流较少时,水流无法将启闭件内的导流通道充满时,水流只会对启闭件的下半部分施加作用力,从而使阀体所受的应力集中在启闭件的下半部分,从而使与启闭件连接的密封圈下半部分受到启闭件摩擦较多,长期如此,容易使密封圈局部磨损严重,从而使密封圈局部密封性下降,影响球阀的使用性能。The existing ball valve sealing ring is fixed and is used once. It will leak if it is slightly worn, and it is difficult to repair and replace, causing the entire ball valve to be scrapped. When the current flow of the ball valve is small in the pipe, the water flow cannot move the opening and closing parts. When the diversion channel is full, the water flow will only exert force on the lower part of the opening and closing part, so that the stress on the valve body is concentrated on the lower part of the opening and closing part, thus causing the sealing ring connected to the opening and closing part to The lower part is subject to more friction from the opening and closing parts. If this happens for a long time, it is easy to cause serious local wear of the sealing ring, thereby reducing the local sealing performance of the sealing ring and affecting the performance of the ball valve.
