Description

Integral forging and pressing flange ball valve

Technical Field

The utility model relates to a valve, in particular to whole forging and pressing flange ball valve.

Background

The opening and closing piece of the ball valve is driven by the valve rod and rotates around the axis of the ball valve. And can also be used for regulating and controlling the fluid. The multi-way ball valve can flexibly control the confluence, the diversion and the switching of the flow direction of the medium on the pipeline, and can close any channel to connect the other two channels. The ball valve is divided into the following parts according to the driving mode: pneumatic ball valves, electric ball valves, manual ball valves.

The application field of the ball valve is very wide, wherein the installation environment of a large part of ball valves is outdoors; the ball valve installed outdoors is provided with a safety device for locking the ball valve in order to avoid the control of the ball valve by irrelevant personnel, wherein the simplest and most convenient safety device is that a lock is locked on a hand wheel of the ball valve to limit the rotation of the hand wheel. The application of the lock not only increases the production cost of the valve, but also has the obvious phenomenon that the lock is easy to attract people to damage, and the phenomenon of losing is easy to occur in the actual operation process by the application of the lock, so that the safety device has higher cost and poorer practicability in actual application.

Further setting as follows: the linkage assembly comprises a first magnetic block fixedly arranged on the linkage rod and a second magnetic block fixedly arranged on the control rod and adsorbed with the first magnetic block.

By adopting the technical scheme, the first magnetic block and the second magnetic block are adsorbed to form detachable linkage between the control rod and the linkage rod.

Further setting the following steps: the linkage rod is provided with a limiting block which moves along with the linkage rod, and the linkage groove is internally provided with a step platform which is matched with the limiting block to limit the linkage rod to be separated from the linkage groove.

By adopting the technical scheme, the linkage rod is limited to be separated from the linkage groove by the cooperation between the limiting block and the step platform, so that the linkage rod is prevented from being lost.

Further setting as follows: the valve comprises a sealing cover sleeved above a valve rod, and a fixing rope is connected between the sealing cover and a valve body.

Through adopting above-mentioned technical scheme, when not controlling the valve action, avoid particle impurity to get into the linkage groove and cause the interference with the closing cap lid in the valve rod top, and the fixed rope that exists can avoid losing of closing cap.

Further setting the following steps: the linkage rod is characterized in that a plurality of positioning holes are distributed in the end face of the valve rod, a plurality of positioning blocks which correspond to the positioning holes one to one and are inserted into the positioning holes are fixedly arranged on the handle, and when the positioning blocks are inserted into the positioning holes, the linkage holes are opposite to the linkage grooves and the linkage rod can move into the linkage holes.

By adopting the technical scheme, the positioning hole is matched with the positioning block to position the handle at the position above the valve rod, so that the linkage groove and the linkage hole are aligned, the linkage rod can smoothly enter the linkage hole, and the operation is more convenient.

To sum up, the utility model discloses following beneficial effect has: the utility model discloses have safety protection function, with low costs, the practicality is stronger.
