Abstract
The utility model relates to a check valve with low resistance, which belongs to the technical field of valve manufacture and mainly consists of a valve body, a connecting rod and a valve plate, wherein, the top end of the connecting rod is installed above the cavity of the valve body through an upper shaft rod; an offsetting spring is arranged on the connecting rod; a rectangle frame is arranged at the upper part of the valve plate; a middle shaft rod is arranged on the valve body; the rectangle frame is sleeved on the middle shaft rod; and two ends of the middle of the valve plate is connected with the connecting rod through a lower shaft pin. When liquid or gas media flow through the valve body from left to right, the media push the valve plate to overcome the offsetting force generated by the valve plate and the offsetting spring to move rightwards. In the movement, the valve is opened after the connecting end surface of the valve plate is contacted with the middle shaft rod; when the media reversedly pass through from right to left, the valve plate deasil rotates to be closed under the action of the self weight and the offsetting spring. The check valve has reliable work operation and a simple structure; the resistance is little when media pass through in the forward direction; and the check valve is suitable for liquid media such as water, oil, gas and the like.
Description
Technical field:
The utility model belongs to technical field of valve manufacturing, is a kind of safety check.
Background technique:
Existing safety check is the sphere structure valve, though have control one-directional fluid flow function, the positive flow of fluid resistance is bigger.
Summary of the invention:
The technical problems to be solved in the utility model is to disclose a kind of lower resistance safety check.
The scheme of the utility model technical solution problem is to adopt valve body, connecting rod, valve plate to constitute the lower resistance safety check, connecting rod is two parallel rhabodoids, the connecting rod top is contained in the cavity top of valve body by upper shaft lever, Returnning spring is housed on the connecting rod, valve plate is in the cavity of valve body, and rectangle frame is arranged at top, and middle axostylus axostyle is housed on the valve body, on the axostylus axostyle, two ends, valve plate middle part were connected with connecting rod by lower shaft pin during rectangle frame was enclosed within.In liquid or gas medium are flowed through valve body from left to right, the reposition force that medium promotion valve plate overcomes valve plate and Returnning spring generation moves right, at the volley after valve plate connects end face and middle axostylus axostyle contacts, because middle axostylus axostyle and the connecting rod placed around the upper shaft lever lower shaft pin through being fixed on the valve plate causes valve plate to produce being rotated counterclockwise around middle axostylus axostyle to the restriction of valve plate, valve open, medium passes through valve smoothly, when medium is desired oppositely to pass through from right to left, the valve thrust of opening that medium produces reduces until disappearance, valve plate dextrorotation then close under the deadweight and the effect of Returnning spring stops medium oppositely to pass through valve.
On valve plate top tongue tray is arranged, constitutes valve plate and seamlessly transit flow guide structure, can further reduce the medium forward by the time valve plate resistance that produces.
The utility model reliable working performance, the medium forward by the time resistance little, simple in structure, be suitable for the safety check of flowing medium such as water, oil, gas body.
Description of drawings:
Fig. 1 is the utility model sectional view;
Fig. 2 is the A-A view of Fig. 1.
Embodiment:
The utility model is made of valve body 1, connecting rod 3, valve plate 6, connecting rod 3 is two parallel rhabodoids, connecting rod 3 tops are contained in cavity 2 tops of valve body 1 by upper shaft lever 4, Returnning spring 5 is housed on the connecting rod 3, and valve plate 6 is in the cavity 2 of valve body 1, and rectangle frame 7 is arranged at top, axostylus axostyle 8 in being equipped with on the valve body 1, on the axostylus axostyle 8, two ends, valve plate 6 middle part were connected with connecting rod 3 by lower shaft pin 9, on valve plate 6 tops tongue tray 10 are arranged during rectangle frame 7 was enclosed within.
