Abstract
The utility model discloses a metal sealing check valve with a big-angle sloping plate, comprising a valve body. The two ends of the valve body are provided with an inlet and an outlet with the axial lines thereof on the same horizontal line. The upper side of the valve body is provided with a horizontal valve cover; the valve body is internally provided with a circular ring shaped valve base; the valve body is provided with a valve shaft above the valve base; a round valve plate is articulated in the valve body and on the valve shaft; a sealing ring matching with the circular ring shaped valve base is arranged on the valve plate; the plane where the circular ring shaped valve base inside the valve body has an angle of 30 degrees to 50 degrees with respect to the axial line of the valve body; the valve plate is made of rubber; the rubber valve plate is provided with a round sheet shaped valve plate body which is internally provided with a round sheet shaped reinforcing steel plate; a valve plate neck is arranged at the upper side of the valve plate body; and a valve plate axial hole is arranged at the outer side of the valve plate neck. The axial lines of the plane of the valve base and the valve body of the utility model have a large angle; the valve plate is light in weight; the valve plate neck is bendable; when the check valve is in use, the opening force is relatively low and the flow resistance is also low; and as the valve plate neck of the valve plate is bendable, the rubber valve plate is gradually stuck to the valve base of the valve body from the upside to the downside so as to substantially remove the water hammer phenomenon when the check valve is closed.
Description
Technical field
The utility model relates to the valve seal seat and the valve plate of a kind of Swing check valve, particularly a kind of Swing check valve.
Background technique
Safety check is called check valve or one-way valve again, safety check is the power that fluid flow to produce in the tube road and the valve that opens and closes automatically, safety check is the valve that can stop fluid to flow backwards automatically, the flap of safety check is opened under fluid pressure action, allow fluid flow to outlet side from suction side, when suction side pressure was lower than outlet side, flap was closed under factor effects such as fluid pressure difference, gravity own automatically in case the fluid stopping body flows backwards.Safety check has Swing check valve, and Swing check valve is that level is used.Swing check valve has valve body, two ends of valve body has import and the outlet of axis on same horizontal line, and the upside of valve body has the valve gap of level, and ring-shaped valve seats is arranged in the valve body, valve shaft above valve seat is arranged, in the valve body, be hinged with the circular valve plate that matches with ring-shaped valve seats on the valve shaft on the valve body.In the prior art, open plane, round ring seat place and the axis normal of valve body or the angle that has 85 degree ~ 90 to spend in the formula check valve body, valve plate is the metal valve plate.This Swing check valve in use, because of the weight of metal valve plate is bigger, opening force is bigger, flow resistance is also bigger, when closing, water hammer is more serious.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, and it is less to propose a kind of opening force, and flow resistance is also less, when closing, and the unconspicuous large-angle inclined sheetmetal sealing safety check of water hammer.
The utility model is realized with the following method.
Large-angle inclined sheetmetal sealing safety check has valve body, two ends of valve body has import and the outlet of axis on same horizontal line, the upside of valve body has the valve gap of level, round ring seat is arranged in the valve body, valve shaft above valve seat is arranged on the valve body, in the valve body, be hinged with the circular valve plate that matches with round ring seat on the valve shaft, the seal ring that matches with round ring seat is arranged on the valve plate, the plane, round ring seat place in the valve body and the axis of valve body have the angle of 30 degree ~ 50 degree, valve plate is the rubber valve plate, and the rubber valve plate has disc valve plate body, and disc reinforcement steel plate is arranged in the valve plate body, the upside of valve plate body has the valve plate neck, and there is the valve plate axis hole in the outside of valve plate neck.
The plane, ring-shaped valve seats place in the utility model valve body and the axis of valve body have the angle of 30 degree ~ 50 degree, the weight of valve plate is less, the valve plate neck of rubber valve plate can be crooked, in use, opening force is less, and flow resistance is also less, when closing, the rubber valve plate can be crooked because of the valve plate neck, so the rubber valve plate is to be attached to gradually from the top down on the valve seat of valve body, eliminates the water hammer when closing basically.
Below in conjunction with accompanying drawing, the utility model is further described.

Fig. 1 is the main cross-sectional schematic that seals safety check according to a kind of large-angle inclined sheetmetal that invention scheme of the present utility model proposes;
Fig. 2 is that schematic representation cuts open in the side-looking office of Fig. 1;
Fig. 3 is that schematic representation cuts open in the master office of looking of valve plate;
Fig. 4 is the cross-sectional schematic of bowing of Fig. 3.
Embodiment
Among Fig. 1 ~ Fig. 4, large-angle inclined sheetmetal sealing safety check has valve body 1, two ends of valve body has the import of axis on same horizontal line and outlet 2,3, the upside of valve body has the valve gap 4 of level, round ring seat 5 is arranged in the valve body, valve shaft 6 above valve seat is arranged on the valve body, in the valve body, be hinged with the circular valve plate 7 that matches with round ring seat on the valve shaft, the potted line 8 that matches with round ring seat is arranged on the valve plate, the plane, round ring seat place in the valve body and the axis of valve body have the angle a of 30 degree ~ 50 degree, valve plate is the rubber valve plate, the rubber valve plate has disc valve plate body 9, disc reinforcement steel plate 10 is arranged in the valve plate body, and the upside of valve plate body has valve plate neck 11, and there is valve plate axis hole 12 in the outside of valve plate neck.
