And other point of the structure of the lower pressure valve, but due to the relatively rare, ordinary hard to run into and use also narrow, this place will no longer say more. Its structure and by the end of valve, valve body and disc and the valve is the same. First of all, let's look at a fixed to reduce pressure type to reduce disc along the body check valve core straight line slide, turnbuckle within the check valve can only be installed on the level of pipeline, the high-pressure small-bore check valve disc may deem appropriate and use the ball. Butterfly check valve by single and double disc type and mostly type three, the main three ways according to the front of the valve diameter, goal is to avoid flow media resting or counter-current, abate hydrodynamic shocks. Butterfly check valve has simple structure, can only be installed on the level of pipeline, tightly closed. Q: reduce the installation of pressure valve structure and its use classification a: reduce the pressure valve according to its structure mode can be divided into: about floating up and down type, fixed lower stress, elastic lubricating oil and oily tightly closed four; According to the passage and can be divided into: direct type, Angle type and three-pass, three general formula can be divided into two t-shaped and l-shaped; According to the petition forms can be divided into: turnbuckle type signatures, signatures of the flange and welding type 3 kinds. Oily around tightly closed lower pressure valve valve seat valve pin shaft rotate within the check valve. Straight-through butterfly check valve medium inlet channel direction and seat straight channel direction; Vertical up and down type check valve, the medium into the Marine valve outlet channel direction and seat in the same direction, its a straight-through flow resistance is small. The bottom to tell you about several kinds of structure to reduce pressure valve and installation forms its unique place. Disc upper part and lower part of the cover processing has a guide sleeve, Jane Jane disc guide can free up and down inside the valve light guide Jane, when media downstream, the disc by medium thrust open, and when the media stop flow, the disc on the fall down on the seat, the backup utility block media. Butterfly check valve body style and the valve (same But with the valve general) The fluid resistance coefficient of, because of this it is bigger. 。 Floating up and down of the lower pressure valve disc in disc, seat channel around the axis of rotation of a rotary motion, due to the channel into a streamline in the Industrial Valves, flow resistance is smaller than l butterfly check valve, suitable for use in low flow rate and flow not often change the large diameter of occasions, but is not suitable for pulsating flow, the tightly closed performance than but up and down. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
