Q:What are the advantages of a flanged plunger valve?

Shanghai Guardian valve believes that the design and manufacture of flanged plunger valve is to solve the defects of the common stop valve.The general cut-off valve seal with blank root filling, cannot eliminate leakage and seal from the valve flap and valve channel or plane angle seal (metal seal), the sealing surface caused by abrasion between the metal leakage and maintenance difficulties.

Q:Where is the difference between the double flange limit expansion joint and the double flange transmission joint?

Advantages: a large amount of expansion, convenient installation. Features: applicable to both ends of the upper flange connection pipe

Q:How to set the bending coefficient of SolidWorks sheet metal base flange?

The formula is as follows:L=0.5 pi * (R+K coefficient X T) * (theta /90)L: sheet metal unfolding length (Developed, length)R: inner radius at bend (Inner, radius)T: material thicknessBend angleY coefficient: a constant determined by the position of the Neurtal bend line, whose default value is 0.5 (the so-called "bend midline"). You can set its default value in config initial_bend_factorIn sheet metal design practice, the commonly used sheet metal flattening calculation formula is based on the K coefficient, the range is 0~1, which indicates the resistance of the material to be stretched when bending. The relationship with the Y coefficients followsY coefficient = (PI /2) * K coefficient

Q:What are the application technologies of welding flanges?

Two. The welding flanges are usually made of forging or forging. When made of steel or shaped steel, the following requirements must be met:1, welding flange should be ultrasonic testing, no delamination defects; 2, should be rolled along the direction of steel cutting into strips, bent by welding into a ring, and make steel surface forming ring cylinder. The steel plate directly machined into the butt welding neck flange butt weld shall not;
