The output line of high-pressure pneumatic butterfly valve with manual operation is connected reversely When this kind of ball honing device is used, after the tool rest of the ordinary lathe is removed, the tool rest position wheel installed on the slide box is driven to rotate, and the combination of these two movements makes the abrasive particles on the slide box. After being expanded with a spring mandrel, the machined sphere is installed on the surface of the honed sphere to form a striated honing track. Here we are honing the two centers of an ordinary lathe. When honing, shake the number of revolutions of the hand grinding head and the ball on the slide box, which can be adjusted by the handle of the ball surface after honing test, so that the oilstone bar on the inner cone of the honing head meets the track and mass of the ball surface. Kerosene is used for cold contact in honing, and a certain pressure is exerted on the surface of the sphere through the action of the spring. In order to ensure that the oilstone bar can be in uniform contact with the surface of the sphere, the honing head adopts a floating structure, and the position of the rotation axis of the honing head relative to the ball center can be automatically corrected during honing by the action of the joint bearing and the ball head shaft. The sphere rotates under the drive of the machine tool spindle, and the honing head is lubricated in the belt through the ball head shaft, the center shaft and the rear shaft.
Precautions for valve installation:
During valve installation, filter and flushing valve shall be set to prevent metal, sand and other foreign matters from entering the valve and damaging the sealing surface; In order to keep the compressed air clean, oil-water separator or air filter shall be set in front of the valve; Considering that the working state of valves can be checked during operation, instruments and check valves need to be set; In order to maintain the operating temperature, thermal insulation facilities shall be set outside the valve; For installation behind the valve, safety valve or check valve shall be set; In consideration of the continuous operation of the valve and the convenience of danger, a parallel system or bypass system has been set up.
