Embodiment Construction

[0016] The specific implementation manner of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings.

[0017] Such as figure 1 As shown, the ball core check valve includes a valve body and a valve core. The body I and the valve body II are sealed through the flange surface.

[0018] The inlet channel is set in the valve body I1, the outlet channel is set in the valve body II2, the ball valve core 4 is specifically set in the outlet channel, the ball valve core can move in the outlet channel, and the ball valve core can be blocked when it moves to the inner end of the inlet channel. Live in the entrance channel to achieve non-return.

[0019] The inner end of the inlet channel of the valve body Ⅰ1 is an annular arc surface structure, the curvature of the arc surface structure is consistent with the curvature of the outer surface of the ball valve core, and the non-return sealing performance is ...

Abstract

The invention discloses a ball-element check valve. The ball-element check valve comprises a valve body and a valve element. The valve element is arranged in a valve cavity of the valve body, an inlet channel is formed in one side of the valve body, and an outlet channel is formed in the other side of the valve body; the valve element is a ball valve element capable of plugging the inlet channel; a limiting block for preventing the outlet channel from being plugged is arranged in the valve cavity. The valve element of the check valve is a ball, the structure is simple, repairing and maintaining are convenient, and cost is low; as rubber lining layers are arranged on the inner wall of the valve body and the outer layer of the valve element, the valve body and the valve element are small in abrasion, long in service life, good in sealing performance, stable and reliable.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a novel ball core check valve. Background technique [0002] The existing check valve has complex structure, cumbersome manufacture, high cost, and is not easy to maintain; and the existing check valve has poor sealing performance, and the internal parts of the valve are easily damaged after long-term use, resulting in check failure and affecting normal use. It is stable and reliable Poor sex. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a ball core check valve to achieve the purpose of simple structure and stable and reliable use. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [0005] A ball core check valve, including a valve body and a valve core, the valve core is arranged in ...
