Abstract
The invention discloses a gate valve gate. A channel for lifting a valve rod (1) is arranged in a longitudinal center of a gate (3). The gate valve gate is characterized in that: the whole gate (3) has a circular shape; a groove (5) is formed on a side wall of a sealing surface of the gate (3) in two schemes respectively; a valve rod nut (4) is arranged in the groove (5) which is formed on the gate (3); and a lug (7) or a stopper (2) formed by the groove (5) can serve as a lifting blocking wall of the valve rod nut (4) and is not limited by the thickness of a side face of the gate (3). The longitudinal height of the gate (3) is reduced to the greatest degree, and the cost of raw materials of a valve cover and the gate (3) is reduced.
Description
Technical field
Originally be the parts flashboard that invention relates to the sealing keying of a kind of gate valve field, especially gate valve.
Background technique
Gate valve is mainly by valve body, valve gap, handwheel, valve rod, flashboard, valve seat constitutes, valve rod and Stem Mut are connected in the connecting groove at flashboard top, because the flashboard of gate valve is the rise-fall type sealing, so arc height that vertically highly directly affects valve gap of flashboard, if can seal under the constant situation of bore, reduce the vertical height of flashboard, the indirect arc height that just can reduce valve gap, thereby reduced the cost of material of valve gap, also reduced the height of integral valve, but general flashboard front is the sealing surface of a circle, and the connecting groove of protrusion is arranged at the top, be inverted T-shaped in the groove, want under the constant situation of sealing surface bore, reduce the vertical height of flashboard, has only the height that lowers connecting groove, such as the gate valve that is the 100mm bore, usually the thickness of flashboard side top is no more than 50mm, and the Stem Mut diameter is not less than 30mm, if directly reduce the height of connecting groove, then the thickness low LCL of both sides sealing face does not have the space that the retaining wall of flashboard lifting is set, so be subjected to the restriction of flashboard thickness, can not have implemented.
Summary of the invention
For solving above-mentioned technical barrier, the invention provides a kind of gate valve flashboard, this flashboard can seal the vertical height of reduction flashboard under the constant situation of bore, and is not subjected to the flashboard thickness limits.
The invention provides two kinds of technological schemes, scheme one: flashboard longitudinal center is provided with the passage that is used for the valve rod lifting, sidewall at the flashboard sealing surface is provided with groove, this groove is recessed in the passage of valve rod lifting from flashboard left side or right side, and the block that the formation of this groove nature is protruded is used for the retaining wall that Stem Mut is connected with flashboard.During installation, Stem Mut directly stretches to the channel center in the flashboard in the groove, and valve rod is connected with Stem Mut.
Scheme two: the longitudinal center of flashboard is provided with the passage that is used for the valve rod lifting, sidewall at the flashboard sealing surface is provided with groove, this groove is down to fall in from flashboard longitudinal center top, from flashboard sealing front, groove inwall both sides all are provided with projection, one of them projection is trapezoidal plane of inclination, and another projection is down trapezoidal inclined-plane; Be the plane of inclination in the Stem Mut two bottom sides, face the base planing surface and be " ship " shape.Placement is installed: stretch into fully to Stem Mut in the groove that colludes flashboard top into that radian is arranged of the side that the Stem Mut base is long, then Stem Mut is moved horizontally to channel center in the flashboard toward colluding into opposite direction, last valve rod is connected with Stem Mut.
Two kinds of schemes that the present invention adopts are provided with groove at the sidewall of flashboard sealing surface, Stem Mut is installed in the flashboard inside grooves, the retaining wall that projection that its groove forms or block can be used as the Stem Mut lifting, not limited by the flashboard lateral thickness, reduce the vertical height of flashboard to greatest extent, also reduced the raw-material cost of valve gap and flashboard.
Description of drawings
Be described in further detail below in conjunction with the embodiment of accompanying drawing the gate valve flashboard.
Fig. 1 is the front section view of novel flashboard scheme one.
Fig. 2 is the front section view of novel flashboard scheme two.
In the drawings, 1. valve rod, 2. block, 3. flashboard, 4. Stem Mut, 5. groove, 6. spill guide-track groove, 7. projection.
Embodiment
Gate valve flashboard scheme one as shown in Figure 1, flashboard 3 integral body are the cake shape, flashboard 3 longitudinal center are provided with the passage that is used for valve rod 1 lifting, sidewall at flashboard 3 sealing surfaces is provided with groove 5, this groove 5 be from flashboard 3 left sides or the right side recessed to the channel direction of valve rod 1 lifting, recessed track is consistent from the track that groove 5 stretches into Stem Mut 4, it is lower slightly that the height of groove 5 is positioned at flashboard 3 tops, its size of flashboard 3 plates according to different sizes is also different, suppose that flashboard 3 thickness are 50mm, then the optimum height of flashboard 3 grooves 5 is positioned at the lower slightly 10mm in flashboard 3 tops, forms one and can be used to the block 2 that Stem Mut 4 is connected with flashboard 3 above groove 5.Stem Mut 4 about 1/3rd profiles above the waist is the square shape, and 2/3rds profiles of the lower part of the body are cylindric, flashboard 3 when mounted, Stem Mut 4 is from the flat channel center that extend in the flashboard 3 of 5 mouthfuls of horizontal saliva of groove, valve rod 1 is connected with Stem Mut 4 again.Be provided with longitudinal concave guide-track groove 6 on both sides, flashboard 3 side, be used to place the long rails in the valve body in this groove 5.
Gate valve flashboard scheme two as shown in Figure 2, flashboard 3 integral body are the cake shape, the longitudinal center of flashboard 3 is provided with the passage that is used for valve rod 1 lifting, sidewall at flashboard 3 sealing surfaces is provided with groove 5, this groove 5 is down to fall in from flashboard 3 longitudinal center tops, from flashboard 3 sealing fronts, groove 5 inwall both sides all are provided with projection 7, one of them projection 7 is trapezoidal plane of inclination, another projection 7 is down trapezoidal inclined-plane, and the position of two projections 7 distance is just colluded into the space of groove 5 with Stem Mut 4 and decided.Be the plane of inclination in Stem Mut 4 two bottom sides, face the base planing surface and be " ship " shape, and wherein a side be more longer slightly than opposite side.The side that Stem Mut 4 bases are long has in the groove 5 that colludes flashboard 3 tops into of radian to Stem Mut 4 and stretches into fully during concrete the installation, then Stem Mut 4 past opposite directions of colluding into are moved horizontally to the channel center in the flashboard 3, valve rod 1 is connected with Stem Mut 4.Both sides, flashboard 3 side are provided with longitudinal concave guide-track groove 6, are used to place the long rails in the valve body in this groove 5.
In scheme one and scheme two, the formed groove 5 of the sidewall of flashboard 3 sealing surfaces, flashboard 3 increases corresponding thickness with its groove 5 shapes, and the sealing surface at the two ends of flashboard 3 can be according to different gate valve technical requirementss, form wedge shape or parallel etc.
