ANSI 150LB Stainless steel wafer check valve

Stainless steel wafer check valveis also known as reverse flow valve , check valve, back pressure valve, one-way valve.This kind of valve depends on the flow of the medium itself in the pipeline and automatically open and close the force, belongs to a kind of automatic valve. Check valves are used in piping systems to prevent backflow of media, to prevent the reversal of pumps and their driving motors, and to prevent the release of media in containers.Check valves can also be used in piping where pressure may rise above the primary system pressure to supply the secondary system.

Check valves can be used on all kinds of media depending on the material. Check valve installed in the pipeline, that is, become one of the complete pipeline fluid components, the disc opening and closing process will be affected by the transient flow state of the system where it is;In turn, the disc's closing behavior has an effect on the flow state.Check valve is characterized by large load variation, small opening and closing frequency, a put into closed or open state, the applicable cycle is very long, and does not require the movement of parts.But once the switch requirements, must be flexible, this requirement is more demanding than the common mechanical movement.Due to the check valve in the most practical use, qualitatively determine for fast shut down, and at the instant of the check valve is closed, the medium is a direction, with the disc in closing, the medium from the rapid rate of maximum back down to zero, while the pressure rise rapidly, generating possible damage to pipeline system of water

Βαλβίδα αντεπιστροφής γκοφρέτας ANSI 150LB από ανοξείδωτο χάλυβα

Η βαλβίδα αντεπιστροφής από ανοξείδωτο χάλυβα είναι επίσης γνωστή ως βαλβίδα αντίστροφης ροής

, βαλβίδα αντεπιστροφής, βαλβίδα αντίστροφης πίεσης, βαλβίδα μονής κατεύθυνσης. Αυτό το είδος βαλβίδας εξαρτάται από τη ροή του ίδιου του μέσου στον αγωγό και ανοίγει και κλείνει αυτόματα τη δύναμη, ανήκει σε ένα είδος αυτόματης βαλβίδας.
