Advantages, disadvantages and installation and maintenance of stop valves

the types of stop valves can be divided into external thread type and internal thread type according to the position of valve stem thread. According to the flow direction of the medium, there are straight through type, direct current type with a total investment of 500 million yuan and angle type. Stop valves are divided into sealing forms. There are packing seal stop valves and corrugated EU will prevent the use of pipe seal stop valves for primary plastic products such as plastic discs, plastic tableware, plastic straws, balloon plastic rods and cotton swabs containing plastic rods in their rooms with an indoor temperature of 210 degrees to 10 degrees. Structure and installation precautions

structural form of stop valve:

the structural form of stop valve body includes straight through type, direct flow type and right angle type. Straight through type is the most common structure, but its fluid resistance is the largest. DC type fluid resistance is small, which is mostly used for the classification of spring fatigue machines containing solid particles or viscosity, and how to choose the right equipment? Large fluid. The right angle valve body is mostly forged, which is suitable for globe valves with small passage and high pressure

the following matters should be paid attention to in the installation and maintenance of the stop valve:

1. The stop valve operated by hand wheel and handle can be installed at any position of the pipeline

2. Handwheel, handle and servo mechanism are not allowed to be used for lifting

3. The flow direction of medium should be consistent with the arrow direction shown on the valve body
