Product Description

H42 Spring loaded Vertical check valve

Lift check valve is a check valve in which the disc, sometimes called a lift, can be lifted up off its seat by higher pressure of inlet or upstream fluid to allow flow to the outlet or downstream side.Vertical check valve due to the pressure of the inlet medium in the pipeline, and to overcome the spring resistance make the valve opened or closed.When the inlet pressure of medium below the outlet, the spring into the valve core seat and make the valve closed, stop medium counter-current, start-stop function back.Vertical check valve is widely used in chemical industry, liquefied petroleum gas, fluid, etc.Check valve according to its structure, can be divided into the vertical check valve, swing check valve and butterfly check valve.

Working principle

Working principle of H42 Spring loaded Vertical check valve

1, When the medium flow direction by the regulation, the disc force by the medium effect, be opened.Medium counter-current, due to the weight of the disc and disc, the function of reverse force by the medium and the valve seat valve sealing surface closed and closed, to achieve the purpose of preventing medium counter-current.
2, Vertical check valve body and disc sealing surface is made of stainless steel welding.
3, The length of the vertical check valve structure according to the provisions of the GB12221-1989 flange size according to the provisions of the JB/T79-1994.

Installation of H42 Spring loaded Vertical check valve

1, The vertical check valve must plug on both ends of the channel, there are dry indoor ventilation.If long-term storage, should often check the rust protection.
2, Before the installation, the vertical check valve should be cleaned, and eliminate the defects caused by/in transit.
3, when installation, must be carefully check the mark on the check valve and nameplate is in line with the use requirement.
4, The vertical check valve installed in vertical pipe runs.
