Abstract
The utility model relates to a guiding-positioning structure of a flat gate valve, comprising a valve body, a valve cover, gate plates, a valve seat, a valve rod, a bracket and a driver. The valve body and the valve cover are respectively and coaxially connected with a machined flange by adopting studs, the bracket is coaxially and fixedly installed on the valve cover, the valve rod is arranged in the bracket coaxially, the driver is installed at the upper end of the valve rod above the bracket, the gate plates are coaxially installed at the lower ends of the valve cover and the valve rod in the valve body, the valve seat used for sealing the gate plates is arranged in the valve body, the valve seat and the gate plates are attached to be sealed, limiting bosses are symmetrically and respectively arranged on each mirror image on the inner walls of the valve bodies on the two side end surfaces of each gate plate, and the two limiting bosses are in centrosymmetric distribution with a channel. According to the guiding-positioning structure, the structure is simple, the processing is convenient, the guiding of the gate plates and the flotation of the valve seat are independent completely, the sealing performance is improved, the floatation of the valve seat can not be affected by the opening or the closing of the gate plates, so that the guiding-positioning structure of the flat gate valve has obvious advantages in the side mounting of the valve, and is suitable for the flat gate valves with various pressure apertures.
Description
Technical field
The utility model belongs to the valve class, relates to plate valve, especially the guide-localization structure of plate valve.
Background technique
Plate valve is that a kind of closure member is the slide-valve of parallel flashboard, and the impacting force that flashboard is applied to valve seat is to be controlled by the pressure medium that acts on flashboard or floating valve seat.In the ordinary flat gate valve; The active force that flashboard receives when valve working acts on the valve seat; Valve seat is floated be affected, particularly when valve is in the installation of side position, it is particularly evident that flashboard receives the influence of self gravitation effect; Cause flashboard pod apertures and valve body medium channel disalignment, cause the sealability of valve to reduce thus.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of existing technology, and a kind of guide-localization structure that makes things convenient for the flashboard positioning and guiding and guarantee the plate valve of sealing is provided.
The utility model solves its technical problem and takes following technological scheme to realize:
A kind of plate valve guide-localization structure comprises valve body, valve gap, flashboard, valve seat, valve rod, support and driver, and valve body and valve gap adopt through made respectively flange that double-screw bolt is coaxial to be connected; The coaxial support that installs on valve gap; Coaxial operation has valve rod in this support, and the valve rod upper end above support is equipped with driver, the coaxial installation flashboard in the valve rod lower end in valve gap and valve body; In valve body, be provided with the valve seat of sealing damper; Valve seat and flashboard are fitted and are sealed, and it is characterized in that: each mirror image symmetry is shaped on a positive stop lug boss on the valve interior wall of flashboard both sides end face, and these two positive stop lug boss and channel center are symmetrically distributed.
And said positive stop lug boss is on the valve interior wall of flashboard both sides, directly to make.
The advantage and the good effect of the utility model are:
1, this position structure respectively casts out a positioning boss on the place, two sides of flashboard valve body; Go out accurate dimensions through machining, during valve side dress, flashboard slides along spacing guide ledges; Thereby the positioning action of playing can guarantee effectively that flashboard pod apertures and valve channel are coaxial.
2, the utility model is simple in structure, and is easy to process, and floating of the guiding of flashboard and valve seat is independent fully; Improve sealability; The unlatching of flashboard, close and can not influence floating of valve seat, in valve side dress, have clear superiority, and be applicable to the plate valve of various pressure bores.
Description of drawings
Fig. 1 is the utility model structural front view;
Fig. 2 is that the A-A of Fig. 1 is to sectional view.
Embodiment
Below in conjunction with accompanying drawing and through specific embodiment the utility model is done further to detail, following examples are descriptive, are not determinate, can not limit the protection domain of the utility model with this.
A kind of plate valve guide-localization structure; Comprise valve body 6, valve gap 4, flashboard 5, valve seat 8, valve rod 3, support 2 and driver 1, valve body and valve gap adopt through made respectively flange that double-screw bolt is coaxial to be connected the coaxial support that installs on valve gap; Coaxial operation has valve rod in this support; Valve rod above support upper end is equipped with driver, and the coaxial installation flashboard in the valve rod lower end in valve gap and valve body is provided with the valve seat of sealing damper in valve body; The sealing of fitting of valve seat and flashboard, flashboard under the driving of valve rod with the able to turn on or off medium channel of axial displacement.
The innovative point of the utility model is:
Each mirror image symmetry is shaped on a positive stop lug boss 7 on the valve interior wall of flashboard both sides end face; These two positive stop lug boss and channel center are symmetrically distributed; And adopt forging type to make; Also can adopt the mode of installing, for directly making mode, the mode of directly making through casting can go out accurate dimensions through machining in the present embodiment accompanying drawing.During valve opening and closing, flashboard slides along the positive stop lug boss of both sides, and positive stop lug boss supports flashboard, and flashboard is played the positioning and guiding effect, is applicable to the plate valve of various pressure bores.
Claims (2)
1. the guide-localization structure of a plate valve comprises valve body, valve gap, flashboard, valve seat, valve rod, support and driver, and valve body and valve gap adopt through made respectively flange that double-screw bolt is coaxial to be connected; The coaxial support that installs on valve gap; Coaxial operation has valve rod in this support, and the valve rod upper end above support is equipped with driver, the coaxial installation flashboard in the valve rod lower end in valve gap and valve body; In valve body, be provided with the valve seat of sealing damper; Valve seat and flashboard are fitted and are sealed, and it is characterized in that: each mirror image symmetry is shaped on a positive stop lug boss on the valve interior wall of flashboard both sides end face, and these two positive stop lug boss and channel center are symmetrically distributed.
