Gate valve

Abstract

The present invention relates to a gate valve (100) comprising: a valve blade (120) for closing an opening (112) of a valve housing (110); a valve rod (130) which connects to the valve blade (120) and can move vertically and horizontally; a guide housing (140) which is connected to the outside of the valve housing (110) and is provided with L-motion block guide grooves (142) on the interior surface of both sides; an L-motion block (150) which is connected to the valve rod (130), and on both sides of which guide rollers (151) that are driven by being inserted into the L-motion block guide grooves (142) are installed; a driving block (160) which is connected to the upper and lower portions of L-motion block (150) by means of at least one link (155); a tensile elasticity means (170), at least one of which is installed between the L-motion block (150) and the driving block (160); and a vertical driving means (180) for vertically driving the driving block (160). 본 발명은 밸브 하우징(110)에서 개구부(112)를 폐쇄할 있는 밸브 블레이드(120);와, 상기 밸브 블레이드(120)에 연결되며, 상하 운동 및 평 운동을 할 있는 밸브 로드(130);와, 상기 밸브 하우징(110)의 외측에 연결되며, 엘 모션 블록 가이드 홈(142)이 양측 내면에 형성되어 있는 가이드 하우징(140);과, 상기 밸브 로드(130)에 연결되며, 양 측면에 상기 엘 모션 블록 가이드 홈(142)에 삽입되어 구동되는 가이드 롤러(151)가 설치되는 엘 모션 블록(L-Motion Block)(150);과, 상기 엘 모션 블록(L-Motion Block)(150)에 상측과 하측에 각각 하나 이상의 링크(155)를 통하여 연결되는 구동 블록(160);과, 상기 엘 모션 블록(L-Motion Block)(150)과 상기 구동 블록(160) 사이에 하나 이상 설치되는 인장 탄성 단(170);과, 상기 구동 블록(160)을 상하로 구동하는 상하구동 단(180); 을 포함하여 구성되는 것을 특징으로 하는 이트 밸브(100)에 관한 것이다.

Description

technical field [0001] The present invention relates to a gate valve (100). The gate valve is characterized in that it comprises: a valve plate (120), where the valve shell (110) is closely attached to the valve seat (Valve- seat) (111), which can seal the opening (112) from the inside; the valve stem (130), which is connected to the valve plate (120), can pass through the bellows (131) to maintain airtightness from the The inside of the valve casing (110) protrudes outward, and can move up and down and horizontally; the guide seat (140) is connected to the outside of the valve casing (110), and L action block guide grooves ( 142), the L action block guide groove is formed by an up and down drive interval groove (143) formed in the up and down direction and an open and close drive interval groove (144) formed in the horizontal direction, the open and close drive interval groove Facing the sealing direction (c) and continuously formed on the upper side of the groove (143) in t...

AI Technical Summary

Problems solved by technology

[0010] The object of the present invention is to solve the problems existing in the existing invention, and to provide a valve that uses only one drive unit, and its structure is not only simple and reliable, but also can perform sealing action or opening action, thereby preventing the Interference of various constituent elements installed inside the gate valve, or the problem that pollutants generated due to mechanical wear enter the processing chamber, so that the operation can be performed effectively, wherein when the sealing operation is performed, the valve plate from After the open position is moved longitudinally to the intermediate position, the intermediate position is moved transversely perpendicular to the longitudinal direction to the sealing position for sealing, and the opening action is performed in the reverse order of the sealing action
