Description
The present invention relates to a gate valve, and more particularly, to a blind valve type gate valve capable of opening and closing a channel while maintaining airtightness such as a blind valve.
The blind valve is installed on the piping to shut off or open the fluid flow, or to block or separate the fluid inflow or mixing between the pipelines of the different kinds of fluids. .
A gate valve is a valve that is installed in the middle of a pipeline to shut off the flow path and is a valve that is not suitable for fine control of the flow rate by using a shutoff plate which is moved at right angles to the flow of the fluid.
Prior art related to such a blind valve includes the application No. 10-2014-0084903 (filed on Apr. 17, 2008) and No. 10-2014-0084906 (filed on Apr. 14, 2014) filed in the Korean Intellectual Property Office, Related prior arts include a number of applications such as application number 10-2008-031487 (filed December 24, 2008).
In the ship or plant industry, gate valves and blind valves must be installed in order to shut off the flow path of the piping and completely shut off the flow of the fluid, and this structure has a problem of increasing plant installation cost.
That is, the conventional blind valve must operate the blind while blocking the flow of the fluid through the gate valve provided at the front end.
A blind valve type gate valve according to the present invention is intended to provide a gate valve capable of performing the function of a blind valve.
A blind valve type gate valve according to the present invention is a gate valve installed between a pipe and a pipe for opening or closing a pipe, comprising: a valve body having front and rear openings; Front and rear seats formed inside the valve body at front and rear openings; A blind inserted between the front and rear sheets; A vertical moving unit for vertically moving the blind to open and shut off the channel; Front and rear ring seats contacting the outer circumferential surfaces of the front seat and the rear seat, respectively; An O-ring provided on the blind contact surface of the front and rear ring sheets and the front and rear seat contact surfaces, respectively; Front and rear horizontal moving rings respectively screwed to outer peripheral surfaces of the front and rear sheets; And a horizontal movement unit for rotating the front and rear horizontal movement rings to push the front and rear ring sheets toward the blind side, wherein the horizontal movement unit comprises: a pair of horizontal coaxial axes arranged on the valve body for horizontally moving; A horizontal driving part for horizontally moving the pair of horizontal coaxial axes; and a horizontal driving part for horizontally moving the pair of horizontal coaxial axes, the horizontals being connected to the protruding parts of the front and rear horizontal moving rings, And a connecting portion for rotating the moving ring.

The vertical movement unit may include a vertically moving coaxial shaft having one end fixed to the blind, and a vertical driving unit rotating the coaxial vertical shaft.
Finally, the vertical movement unit includes a rack gear formed on the side surface of the blind, a guide portion provided on the valve body to guide the movement of the blind, And a driving motor connected to the driving gear to move the blinds together.
The blind valve type gate valve according to the present invention is advantageous in that the front and rear ring seats are brought into close contact with the blind using a horizontal moving unit so that the airtight function of the gate valve can be performed while maintaining airtightness in the form of a blind valve.
Particularly, there is an advantage that the valve can be operated even in the state where the fluid flows.
