Abstract
The utility model discloses a left side open type self-closing check valve. A large flange is arranged in front of a valve body; a water seal is arranged in front of the large valve; a valve is arranged in front of the water seal; the valve is connected with an upper and a lower hinges into a whole; and a small flange is provided with twelve equidistant screw bolt holes. The self-closing check valve has the key technique that the upper hinge and the lower hinge which are positioned at the left side of the end surface of the large valve of the valve are vertically arranged; the equidistant screw bolt holes 7 are moved to the left a certain angle by taking the central line as a standard (the utility model moves an angle of 5 DEG). In that case, after the utility model is mounted the goals ofreduction of the opening resistance of the valve and automatic closing are achieved by utilizing the horizontal force component of the self gravity of the valve.
Description
Technical field
The utility model discloses the self-closing safety check of a kind of left side open type.
Background technique
Defectives such as at present, what generally use in the tap water pump house of countries in the world is Swing check valve, and this safety check exists opening angle little, and resistance to water-flow is big, and energy loss is many, and working life is short.Up to the present, it is big also not see a kind of opening angle on market as yet, and resistance to water-flow is little, can save a large amount of energy, the self-closing safety check of right side open type of long service life.
Summary of the invention
The purpose of this utility model provides that a kind of opening angle is big, and resistance to water-flow is little, can save a large amount of energy, the self-closing safety check of left side open type of long service life.
The technical solution of the utility model is as follows: open type self-closing safety check in a kind of left side comprises valve body, big flange, water seal, valve, upper and lower hinge, little flange and 12 equidistant bolts hole etc.Wherein, be provided with big flange in the valve body front, be provided with water seal on big end face of flange, be provided with valve in the water seal front, valve and upper and lower hinge combine as a whole, and are provided with 12 equidistant bolts hole on little flange.
Key technology of the present utility model is: the upper and lower hinge on big end face of flange the right is vertically arranged, is benchmark with the bolt hole on the little flange 7 with the center line, all to left dislocation several angle (5 ° of the utility model displacements).Like this, the utility model can utilize the deadweight horizontal component of valve to be used as power after installing, the purpose that reaches the opening resistance that reduces valve and close door automatically.
