Abstract
The utility model discloses a gate-board and valve-seat structure for gate valves, comprising a valve body, a valve seat, a gate board and a valve rod. The utility model is characterized in that the board surface of the gate board and the plane surface of the valve seat at an outlet end are respectively and correspondingly provided with at least two through holes, the amount of holes of the gate board and the valve seat are equal, and the matching use between the gate board and the valve seat can achieve the switching state of the holes on the gate board and the valve seat. The utility model has the advantages the travel of the gate board of the gate valve is shortened, and the volume of the gate valve is reduced, which achieves fast switching of the gate valve, suitable for various work places that need to achieve the fast switching of pipeline liquids and has smaller installation space for valves.
Description
The utility model relates to the structure of gate valve, relates in particular to the flashboard and the valve seat construction of gate valve.
Gate valve is widely used on the various pipes of industries such as oil, chemical industry, metallurgy, electric power, it mainly is made up of valve body, valve seat, restrictor bar and flashboard, gate valve is to drive flashboard by restrictor bar to move up and down, make the plane of flashboard and the hole on the valve seat planes is interlaced or connect, thereby realize the keying of gate valve.Although this gate valve is used in large quantities, during owing to operation, the stroke of restrictor bar and flashboard is longer, and feasible bigger, little in some mounting point, that pipeline the is intensive place of gate valve volume that produces is very inconvenient when installing and using; In addition, when opening and closing owing to gate valve, flashboard is subjected to the restriction of stroke, makes ducted fluid can not realize quick break-make.
The purpose of this utility model is to provide flashboard and the valve seat construction that a kind of gate travel is short, can realize the gate valve of quick break-make.
For realizing the purpose of this utility model, the technical solution adopted in the utility model is: the flashboard of gate valve and valve seat construction, comprise valve body, be arranged on two valve seats in the valve channel, the restrictor bar that is arranged on the flashboard between two valve seats and links to each other with flashboard, offer through hole on the valve seat, the bi-side of flashboard offset with the corresponding side of two valve seats respectively, correspondingly offering through hole respectively on the flashboard plate face and on the plate face of gate valve outlet end valve seat, through hole has two respectively at least, and have at least two holes on the plate face, to be vertical arrangement, can realize the break-make in hole on flashboard and the outlet end valve seat when flashboard and valve seat are used.
Hole on the seat board face of described flashboard and outlet end is the strip hole.
The quantity in the hole on the seat board face of described flashboard and outlet end is equal, measure-alike.
Advantage of the present utility model is: shortened the stroke of gate valve flashboard, dwindled the volume of gate valve.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structural front view of the utility model gate valve;
Fig. 2 is the left view of the utility model gate valve.
As shown in Figure 1, 2: two valve seats 2,4 of gate valve are fixed on the valve body 1 with Cock screw 6,7 respectively, flashboard 5 is installed between two valve seats 2,4, two plate faces of flashboard 5 and two valve seats 2,4 are Spielpassung, flashboard 5 links to each other with the flashboard lifting gear by restrictor bar 3, offer mutual three corresponding holes respectively on flashboard 5 and the valve seat 2, the shape in hole is long strip, and the entity part width should be slightly larger than the width in hole between the Kong Yukong.When gate valve was opening state, it is descending gradually that valve rod 3 drives flashboards 5, and flashboard 5 staggers gradually mutually with the hole on the valve seat 2, and gate valve is closed gradually, and entity face on flashboard 5 planes and the hole on valve seat 2 planes are sealed mutually.Otherwise when valve rod 3 drive flashboards 5 were up gradually, the hole on flashboard 5 and the valve seat 2 overlapped gradually and connects, thereby gate valve is opened.The lifting range of gate valve flashboard 5 be two adjacent holes centre distance 1/2nd, thereby dwindled stroke effectively, improved the keying speed of gate valve.
The utility model is not limited to above-mentioned a kind of embodiment, the shape in hole can be circle, triangle, polygonal and various erose hole on flashboard 5 and valve seat 2 planes, but the break-make in hole on flashboard 5 and the valve seat 2 should be able to be realized in the various holes on flashboard 5 and the valve seat 2 when two boards is used.
Claims (3)
1, the flashboard of gate valve and valve seat construction, comprise valve body, be arranged on two valve seats in the valve channel, the restrictor bar that is arranged on the flashboard between two valve seats and links to each other with flashboard, offer through hole on the valve seat, the bi-side of flashboard offset with the corresponding side of two valve seats respectively, it is characterized in that: correspondingly offering through hole respectively on the flashboard plate face and on the plate face of gate valve outlet end valve seat, through hole has two respectively at least, and have at least two holes on the plate face, to be vertical arrangement, can realize the break-make in hole on flashboard and the outlet end valve seat when flashboard and valve seat are used.
2, the flashboard of gate valve according to claim 1 and valve seat construction is characterized in that: the hole on described flashboard and the seat board face is the strip hole.
3, the flashboard structure of gate valve according to claim 1 and 2 is characterized in that: the quantity of corresponding through hole is equal, measure-alike on described flashboard and the outlet end seat board face.
