Abstract
The utility model relates to a valve, in particular to a pneumatic double knife gate valve, comprising a valve rod, a valve body, a cylinder, a stuffing box and a sealing seat. A gate is arranged in the valve body and consists of two gates, namely, a first gate and a second gate which are arranged in the inner chamber of the valve body and are vertical to a channel. The first gate and the second gate are arranged symmetrically taking the axle wire of a valve body channel as the symmetry axis. The valve also comprises a first valve rod, a second valve rod, a first cylinder and a second cylinder which corresponds to the first gate and the second gate respectively, and the first gate, the second gate, the first valve rod, the second valve rod, the first cylinder and the second cylinder are located on the same axes. In the structure, the gate adopts the symmetric double-gate structure, so that the opening and closing time of the gate valve is greatly shortened and the symmetric structure can be adjusted more easily.
Description
Technical field
The utility model relates to a kind of valve, especially a kind of pneumatic double-pole gate valve.
Background technique
Pneumatic disconnecting link valve is a kind of simple in structure, and fluid resistance is little during standard-sized sheet, and behaviour is with flexible, can realize automatic control, convenient for installation and maintenance, the valve of economy and durability, compare with the valve of other kind, therefore the economical and practical advantage of disconnecting link valve is clearly used very extensive at paper industry.
Pneumatic disconnecting link valve is a kind of valve of using as break-make, present employed disconnecting link valve is a Single disc, and valve opening and pass closed procedure all need flashboard to pass through whole runner, and the time of opening and closing is just very long like this, influence system response speed, inapplicable in the place that will seek quickness out with quick closing valve.And structure is asymmetric, and deviation of gravity center need be transferred support during installation, and filler is changed relatively difficulty.
Summary of the invention
The purpose of this utility model is, a kind of unlatching, shut-in time weak point are provided, symmetrical configuration, and filler is easy to pneumatic double-pole gate valve.
The utility model is achieved by the following scheme: a kind of pneumatic double-pole gate valve, comprise valve rod, valve body, flashboard, cylinder, stuffing box, sealing seat, flashboard is arranged in the valve body, it is characterized in that described flashboard is made of two flashboards, be respectively first flashboard and second flashboard, first flashboard and second flashboard are arranged in the inner chamber of valve body, with channel vertical, first flashboard and second flashboard are symmetrical arranged about the medial axis of valve channel, also comprise first valve rod, second valve rod, first cylinder, second cylinder, the output terminal of first valve rod, one end and first cylinder is connected, the other end is fixedlyed connected with first flashboard, the output terminal of second valve rod, one end and second cylinder is connected, the other end is fixedlyed connected with second flashboard, described first flashboard, second lock, first valve rod, second valve rod, first cylinder, second cylinder is on the same axis.
This is provided with employing double-pole brake structure, first flashboard and second flashboard are symmetric design, corresponding with it valve rod, cylinder all are arranged on the same axis, form a symplex structure like this, the time of opening and closing has all shortened, and such symplex structure is more prone to when adjusting.
Of the present utility modelly further be set to: the side at first flashboard and second lock all is provided with sealing seat, and described sealing seat is a floating bushing cartridge type structure, is provided with O shape circle at a sealing seat end corresponding with flashboard.
During being provided with, this design of Sealing Structure can be become one-way sealing, also can be designed to two way sealed, sealing seat is designed to floating bushing cartridge type structure, the end is provided with O shape circle and had both sealed also when the prefastening force spring use, the pressure of medium was pushed flashboard to sealing seat when flashboard cut out, the O shape circle of sealing seat end can limit sealing seat and draw back and allow, and makes sealing seat be close to flashboard, reaches sealing effect.
Of the present utility modelly further be set to: all be arranged on outside the valve body with described first flashboard and the corresponding stuffing box of second lock.
This is provided with the external setting of stuffing box, and is convenient when adding sealing medium like this, also easy more together when changing sealing medium.
Flashboard in the said structure has adopted the double-flashboard symmetrical structure, has shortened the time of gate valve opening and closing greatly, and symmetrical structure also is more prone to adjust.
