Abstract
The invention discloses a swing check valve. The swing check valve is characterized in that a valve cover is fixed at the top of a valve body through bolts, the inside of the valve body is provided with a valve seat, and a valve shaft is arranged inside the cavity of the valve body; one end of a swing arm is mounted onto the valve shaft, and the other end of the swing arm is fixed to a valve plate through a bolt; a sealing ring is mounted on one side of the valve plate, which is in contact with the valve seat. By means of the arrangement above, the movable portion of the valve plate is designed to be suspended, so that the contact area between the valve board and the valve body can be reduced, unnecessary wearing can be avoided; the sealing ring improves the sealing performance between the valve plate and the valve seat.
Description
Technical field
The present invention relates to a kind of valve, is a kind of Swing check valve specifically.
Background technique
At present, for preventing the safety check of aqueous reflux, the active part of valve plate directly contacts with valve body, and both contact segments of long duration all can sustain damage, and airtight quality is unstable.
Summary of the invention
Object of the present invention is the Swing check valve that a kind of wear-resistant good airproof performance is provided.
To achieve these goals, the present invention is bolted valve gap above valve body, the inner valve seat of installing, in described valve body body cavity, valve shaft is set; one end of rocking arm is arranged on described valve shaft, and the other end is bolted valve plate, seal ring is arranged in the side that valve plate contacts with valve seat.
By above setting, the moving part of valve plate of the present invention is unsettled design, has reduced the area of contact with valve body, avoided unnecessary wearing and tearing, and seal ring has improved the sealing of valve plate and valve base chamber.
Accompanying drawing explanation
Now the present invention will be further described by reference to the accompanying drawings.
Fig. 1 is structural representation of the present invention.
In figure: 1, valve body, 2, valve gap, 3, valve seat, 4, valve shaft, 5, rocking arm, 6, valve plate, 7, seal ring.
Embodiment
As shown in Figure 1, the present invention is bolted valve gap 2 above valve body 1, the inner valve seat 3 of installing, in described valve body 1 body cavity, valve shaft 4 is set; one end of Rocker arm 5 is arranged on described valve shaft 4, and the other end is bolted valve plate 6, seal ring 7 is arranged in the side that valve plate 6 contacts with valve seat 3.By above setting, when cutting off the water, the gravity of current and pipe friction power make flow velocity vanishing, occur reflux state, and now Rocker arm 5 declines, and while driving valve plate 6 to be down to valve seat 3, recirculation water is stopped.
Claims (1)
