Valve Body is a main component in the valve. According to the pressure level, there are different mechanical manufacturing methods. For example: casting, forging, etc.
The valve body of medium and low pressure specification usually adopts casting process to produce valve body.
Definition
The "valve" is defined as a equipment in a fluid system to control the direction, pressure, and flow of the fluid. A valve is a device that control the medium (liquid, gas, powder) to flow or stop and control its flow in the piping and equipment
Construction and feature
The
construction is to be built according to the drawing with rules of good
workmanship.
The hydraulically operated gate valves are
built of a welded steel construction (stress released) for a wide range of
inner pipe diameter and working pressure.
Feature:
1.The dredge valve is designed in such a
way that there are no fasteners inside the body
Materials
All
fabricated steelwork used in the construction will be to manufacturing standard
of normal or classification society.
All
materials proposed will be selected to comply with the latest Health and Safety
Rules.
Paint
systems for hull protection will be of the highest quality (Hempel, Inter,
Sigma, Jotun)

application
15.Easy handling and installation due to hosting lugs and compact design
Hexagon bolts are a very common type of bolt and are used in a wide range of applications. The connected parts can be fastened by bolts, nuts, and washers. The function of the ring is to prevent the surface of the connected parts from being damaged when the nut is tightened, and the pressure of the nut is evenly distributed to the surface of the part. The connected parts are machined to have unthreaded through holes. The diameter of the through hole is slightly larger than the thread diameter. The exact size can be checked. When drawing a bolt connection, the nominal length l of the bolt must first be calculated. The bolt length l≈k+m+g1+g2+b1 is calculated after the length is calculated and the standard length l is taken according to the bolt length series. The following figure shows the bolted assembly drawing. The size of bolted joints can be obtained from standard checklists. However, approximate dimensions can be used when drawing threaded fasteners. Where: b1≈0.3d; m≈0.8d; k≈0.7d; e≈2d; d2≈2.2d; c≈0.15dx45; h≈0.15d; e≈2d. More products /news/314.html
