Description
The present invention relates to a valve having an improved operating performance of an open / close plate, and more particularly, to an open / close valve having a structure in which a valve body is in close contact with an inner surface of a valve body, To the operation of the plate.
The opening / closing or directional switching valve is installed in a tube forming a passage of the fluid, and regulates or blocks the flow of the fluid.
In order to perform such operation, an opening / closing member for closing or opening the fluid inlet / outlet port is provided in the inner space of the opening / closing or direction switching valve in accordance with the rotation angle (90 degrees or 180 degrees) And the ball member is often rotatably arranged as the opening / closing member.
Such a ball member must have a size proportional to the diameter of the tube for blocking the inlet or the like. Since a large diameter ball must be used for the large tube, the capacity of the actuator for rotating the ball is also large It must be. Resulting in an increase in production cost, and difficulty in fabrication and repair.
In order to solve such a problem, a segment ball valve in which the shape of the ball member is deformed to reduce its weight is used.
1 shows a structure of such a segment ball valve as disclosed in Korean Patent Publication No. 10-0975337.
The segment ball valve includes a valve body 1, a

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide a valve body which has a simple structure and maintains a better close contact state with the inner circumferential surface of the valve body during operation, To provide a valve of a structure that can be minimized.
It is another object of the present invention to provide a valve having a structure in which the opening and closing means for opening or closing the flow path is simply constituted and can be easily replaced.
According to an aspect of the present invention, there is provided a valve apparatus including a valve body having a working space and a cylindrical side wall surrounding the working space, a shaft installed along a longitudinal center axis of the cylindrical side wall, An inlet port and an outlet port communicating with the working space and extending outwardly from the cylindrical side wall; and an opening / closing plate coupled to the shaft and opening / closing the inlet or outlet according to the rotation of the shaft, An upper disk provided on the upper side of the inlet and the outlet so as to contact the inner circumferential surface of the cylindrical side wall and a lower disk fixed to the lower disk provided on the lower side of the inlet and outlet so as to contact the inner circumferential surface of the cylindrical side wall, Wherein the opening / closing plate has an outer circumferential surface And a curved surface having the same curvature as that of the inner circumferential surface of the cylindrical sidewall is formed on the outer surface of the lower disk and is installed in close contact with the inner circumferential surface.
In addition, the upper disk may be provided with an upper seating groove formed on the upper disk along the outer circumferential surface to have the same length as the upper end of the opening / closing plate and on which the upper end of the opening / closing plate is seated, And a lower seating groove formed at a lower end of the plate so as to have the same shape as the lower end of the plate and on which the lower end of the opening plate is seated is provided and the shaft extends from the shaft to the opening plate between the upper disk and the lower disk, The intermediate support body is further provided with an elastic body for pushing the open / close plate so as to bring the open / close plate into close contact with the inner circumferential surface of the cylindrical side wall, wherein the open / The lower seating jaw, the elastic body, By being supported by the contact of the inner surface and the cylindrical side wall of the group, and that by the elastic member when released from the cylindrical side wall is separated from the upper disc and the lower disc to the other features.
Further, the present invention is characterized in that the cylindrical side wall includes an operating seat which forms an inner circumferential surface thereof and reduces frictional force, and the upper disk and the lower disk are in contact with the operating sheet.
According to another aspect of the present invention, there is provided a flow rate adjusting through hole, which is provided in a direction in which the curvature is formed on the opening / closing plate and gradually increases in size from one side to the other side, .
In the valve according to the present invention, the upper disk and the lower disk always land on the operating seat so that the shaft and the upper and lower disks are not pushed by the fluid pressure, so that the open / Even if pressure is applied, the flow path can be tightly closed to prevent leakage of the fluid.
In particular, since the opening and closing plate can always be brought into close contact with the operating seat by the elastic body provided on the intermediate support body, even if the valve body can not firmly support the shaft, The leakage of the fluid can be minimized by being brought into close contact with the operating sheet.
Further, according to the present invention, when the shaft, the upper and lower disks, and the opening and closing plate are removed from the valve body and taken out, the opening and closing plate can be immediately separated from the upper and lower disks at the time when the opening and closing plate is separated from the cylindrical side wall. It is possible to complete the installation by inserting the open / close plate into the valve body by bringing the open / close plate into close contact with the upper seating jaw of the upper disk and the lower seating jaw of the lower disk, and replacement due to abrasion and deformation of the opening / closing plate can be very easily performed.
Further, since the flow rate adjusting through-hole is formed in the opening and closing plate of the present invention, the flow rate can be adjusted according to the rotation of the shaft, and the entire structure for controlling the flow rate can be very simplified.
