Abstract
The utility model relates to a metal seal check valve with a wide-angle sloping plate. The metal seal check valve comprises a valve body, wherein an inlet and an outlet which are provided with axial lines on the same horizontal line are arranged at two ends of the valve body, a horizontal valve cap is arranged at the upper side of the valve body, an annular valve seat is arranged in the valve body, a valve shaft arranged above the valve seat is arranged on the valve body, a circular valve plate matched with the annular valve seat is hinged in the valve body and on the valve shaft, and an angle of 30-50DEG is formed between the plane in which the annular valve seat is arranged in the valve body and the axial line of the valve body. The angle of 30-50DEG is formed between the plane in which the annular valve seat is arranged in the valve body and the axial line of the valve body, so that when the metal seal check valve is in use, the opening force is small, the flow resistance is smaller; and when the metal seal check valve is closed, the water hammer phenomenon is not obvious.
Description
Technical field
The utility model relates to the valve seal seat 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.This Swing check valve in use, 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, valve body is arranged, 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, the valve base sealing ring is arranged on the valve seat, 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, and the plane, round ring seat place in the valve body and the axis of valve body have the angle of 30 degree ~ 50 degree.
The axis of the utility model valve body inner annular valve plane, seat place and valve body has the angle of 30 degree ~ 50 degree, and in use, opening force is less, and flow resistance is also less, and when closing, water hammer is not obvious.
Below in conjunction with accompanying drawing, the utility model is further described.
Description of drawings
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 the master of valve plate looks schematic representation;
Fig. 4 is the side cross-sectional schematic 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 base sealing ring 6 is arranged on the valve seat, valve shaft 7 above valve seat is arranged on the valve body, in the valve body, be hinged with the circular valve plate 8 that matches with round ring seat on the valve shaft, the seal ring 9 that matches with round ring seat is arranged on the valve plate, and 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.
