Ball valve classification: 1, floating ball valve 2, fixed ball valve 3, elastic ball valve (ie track ball valve) 4, V-ball valve 5, three-way ball valve
Floating ball valve features:
The ball of the ball valve is floating. Under the effect of medium pressure, the ball can generate a certain displacement and press on the sealing surface of the outlet end to ensure the sealing of the outlet end.
The structure of the floating ball valve is simple and the sealing is good. However, the load of the ball bearing the working medium is transmitted to the outlet sealing ring. Therefore, it is necessary to consider whether the sealing ring material can withstand the working load of the ball medium when subjected to high pressure shock. Spheres may shift. This structure is generally used for low and medium pressure ball valves.
Fixed ball valve ball valve features:
The sphere of the ball valve is fixed and does not move after being pressed. The fixed ball ball valve has a floating valve seat. After the medium pressure, the valve seat moves and the seal ring is pressed against the ball to ensure the seal. Bearings are usually mounted on the upper and lower shafts of the ball, and the operating torque is small, suitable for high pressure and large diameter valves.
In order to reduce the operating torque of the ball valve and increase the reliability of the seal, oil seal ball valves have appeared in recent years. Special lubricants are injected between the sealing surfaces to form a layer of oil film, which enhances the sealing performance and reduces the operating torque. , It is more suitable for high pressure and large diameter ball valve.
Flexible ball valve features:
The sphere of the ball valve is elastic. The ball body and the valve seat seal ring are made of metal materials, and the specific pressure of the seal is large. The pressure of the medium itself cannot meet the requirements of the seal, and an external force must be applied. This valve is suitable for high temperature and high pressure media.
The elastic ball is to open a flexible groove at the lower end of the inner wall of the ball to obtain elasticity. When closing the channel, use the wedge head of the valve stem to make the ball expand and seal with the valve seat. Loosen the wedge head before turning the ball, the ball will return to its original shape, so that there is a small gap between the ball and the valve seat, which can reduce the friction and operating torque of the sealing surface.
V-ball valve features:
This type of ball valve is a fixed ball valve, also a single valve seat ball valve. The adjustment performance is the best among the ball valves. The flow characteristic is equal percentage, and the adjustable ratio is 100:1. Its V-shaped incision has a shearing action with the metal seat, especially suitable for media containing fibers, tiny solid particles, slurries, etc.
Three-way ball valve features:
Three-way ball valve has T-type and L-type. T-type can make three orthogonal pipelines communicate with each other and cut off the third channel, which acts as a shunt and a confluence. The L-type can only connect two pipes that are orthogonal to each other. It cannot hold the third pipe at the same time and only play a distribution role.
Product Features 1. The three-way ball valve adopts an integrated structure in its structure. The sealing type of the four-face valve seat has few flange connections and high reliability. The lightweight, two-way three-way ball core is divided into T-type and L-type. Long service life, large flow capacity, low resistance 3, ball valve action type and double acting two types, single-acting feature is that once the power source fails, the ball valve will be in the state of the control system requirements.
PCD Milling Cutter is a rotary cutter with one or more cutters for milling. During operation, each tooth sequentially cuts off the remaining amount of the workpiece. Milling cutters are mainly used to machine planes, steps, grooves, forming surfaces and cutting workpieces on milling machines.
PCD Milling Cutter are used for a wide range of applications such as shoulder milling, slotting and contoured surface milling. Compared with Carbide End Mills, PCD End Mills have the following obvious advantages:
â—Allow faster speed and feed;
â—High stability and it can improve workpiece quality with tight dimensional
â—Especially suitable for machining aluminum, copper and other metals with ultra-precision mirror grinding
â—Optimizes machine tool efficiency by increasing production capacity
