    摘要: The present disclosure provides a check valve connector system for coupling a lateral pipe and a main pipe. The check valve connector system can include a fitting, a saddle member, and a check valve. The fitting can include a first end, a second end, an elbow, and an opening. The opening can be formed between the first end and the second end. The first end can be configured to receive the main pipe. The elbow can extend outwardly from the fitting and can include an aperture. The aperture can include a pear-shaped cross section and can be configured to receive the lateral pipe. The saddle member can be configured to couple the fitting and the main pipe. The saddle member can include a hole for receiving the fitting. The check valve can be disposed between the fitting and the saddle member.

    摘要: A method of making a three-flow-passage valve with a pressure indicator, comprising the steps of constructing a first half housing defining an upper flow passage, a middle flow passage, and a lower flow passage; constructing a second half housing defining the same flow passages; forming an access port through the housing in the middle flow passage; forming a first valve seat with one valve opening; assembling one movable valve opening stopper in the upper flow passage; adjusting the one movable valve opening stopper; forming a second valve seat with one valve opening; assembling one movable valve opening stopper in the upper flow passage; adjusting the one movable valve opening stopper to allow the one movable valve opening stopper in the middle flow passage; combining and sealing the first half housing with the second half housing; and mounting a pressure indicator to the access port.

    摘要: A check valve construction is provided in which a moveable a movable ball having a convex surface resides in a cage having a conical frustum chamber and a seat for the ball. A fluid path between the ball and the cage is defined by the equation: G = D ⁢ ⁢ cos ⁡ ( b - a ) 2 ⁢ ⁢ cos ⁢ ⁢ b - d 2 wherein G is the gap of the narrowest passageway of the fluid path, D is the diameter of the small end of the conical frustum chamber of the cage, d is the diameter of the convex surface of the ball, a is the angle between a vertical diameter of the ball and the position of the narrowest gap on the convex surface of the ball, and, b is the angle between the vertical diameter of the movable element and the position of the small end of conical frustum chamber of the cage.
