Abstract
The utility model provides a soft or hard double sealing mud gate valve, including valve body, valve gap, disk seat, valve rod, flashboard, the valve gap is located valve body upper portion, the disk seat is located in the valve body, the valve rod with the flashboard is connected, the flashboard is followed the valve gap stretches into the valve body and insert in on the disk seat, the disk seat includes skeleton, base and rubber, the skeleton with the valve body is connected, rubber is located in the skeleton, the flashboard passes the skeleton and insert in in the rubber, it is vice that this gate valve uses rubber convex surface and flashboard surface contact to form the soft seal, and after soft seal wear became invalid, disk seat support and flashboard surface formed firmly sealed, this kind of structure disk seat simple to operate, and the difficult scotch of sealed face, sealing performance is more reliable, the more durable long service life of valve.
Description
Technical field
This utility model is related to valve technology field, more particularly to a kind of soft or hard dual-seal mud gate valve.
Background technology
Mud flat gate valve mainly for delivery of on high-pressure slurry pipeline as cut off and turn on pipeline valve.Because making
With dependable performance, open and close torque it is little the advantages of, so using more universal.Conventional steel core mud gate valve is by metal flashboard and gold
Category valve seat forms sealing, but the solid granule in mud is easily accessible sealing surface, during opening and closing, flashboard and valve base sealing
There is Relative friction between face, easily cause scratch phenomenon.
Utility model content
To solve above-mentioned technical problem, the utility model proposes a kind of soft or hard dual-seal mud gate valve, including valve body,
Valve gap, valve seat, valve rod, flashboard, the valve gap is located at the valve body top, and the valve seat is located in the valve body, the valve rod
It is connected with the flashboard, the flashboard stretches into the valve body and inserts on the valve seat from the valve gap;The valve seat includes bone
Frame, base and rubber, the skeleton is connected with the valve body, and the rubber is located in the skeleton, and the flashboard passes through described
Skeleton is simultaneously inserted in the rubber.
Preferably, it is bolted between the valve gap and the valve body, the valve gap is pointed to and is provided with the valve seat
Borehole jack.
Preferably, the valve seat top is provided with two gag lever posts, and the borehole jack is inserted in the gag lever post.
Preferably, the valve stem end is provided with T-shaped section, and the flashboard is provided with corresponding draw-in groove, and the T-shaped section is stuck in institute
State in draw-in groove.
The utility model proposes soft or hard dual-seal mud gate valve have following beneficial effect:This gate valve uses rubber convex surface
Contact to form soft seal pair with gate panel surface, after soft seal wear out failure, valve seat support and gate panel surface form hard sealing, this
Plant structure valve seat easy for installation, sealing surface is difficult scratch, sealing property is relatively reliable, the relatively durable long service life of valve.
Description of the drawings
Technical scheme in order to be illustrated more clearly that this utility model embodiment, below will be to needed for embodiment description
The accompanying drawing to be used is briefly described.
Fig. 1 is structural representation of the present utility model;
Wherein, 1- valve bodies, 2- valve gaps, 3- valve rods, 4- flashboards, 5- skeletons, 6- bases, 7- rubber, 8- bolts, 9- borehole jacks,
10- gag lever posts, 11-T shape sections.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe.
Such as Fig. 1, the utility model proposes a kind of soft or hard dual-seal mud gate valve, including valve body 1, valve gap 2, valve seat,
Valve rod 3, flashboard 4, the valve gap 2 is located at the top of the valve body 1, and the valve seat is located in the valve body 1, the valve rod 3 and institute
State flashboard 4 to connect, the flashboard 4 stretches into the valve body 1 and inserts on the valve seat from the valve gap 2;The valve seat includes bone
Frame 5, base 6 and rubber 7, the skeleton 5 is connected with the valve body 1, and the rubber 7 is located in the skeleton 5, the flashboard 4
Through the skeleton 5 and insert in the rubber 7;Valve seat of the present utility model is by two steel skeletons and the conduct of metab 6
Basic framework, surface revulcanization rubber 7 shapes, and appropriate rubber 7 can be selected according to the extent of corrosion of medium, with lock on valve seat
Two ends respectively have a convex surface of round rubber 7 to contact to form soft seal with the surface of flashboard 4 at the fitted seal of plate 4, when soft seal abrasion
After failure, valve seat support and the surface of flashboard 4 form hard sealing, and this structure is soft or hard dual-seal;
Preferably, fixed by bolt 8 between the valve gap 2 and the valve body 1, the valve gap 2 is pointed at the valve seat
Borehole jack 9 is provided with, the valve seat top is provided with two gag lever posts 10, and the borehole jack 9 is inserted in the gag lever post 10, valve gap 2 and valve
While body 1 connects, gag lever post 10 is inserted in empty set, it is ensured that the axial and circumferential of valve seat are fixed.
Wherein, the connection of valve rod 3 and flashboard 4, its structure is provided with T-shaped section 11 for the end of the valve rod 3, on the flashboard 4
Corresponding draw-in groove is provided with, the T-shaped section 11 is stuck in the draw-in groove.
Inner frame 5 in valve seat then remains for a long time the basic configuration of valve seat and makes it have most enough service life.Valve seat
The soft sealing face of rubber 7 and flashboard 4 are fitted close, and effectively prevent the solid granule in medium to enter sealing surface, it is to avoid
Sealing surface abrades phenomenon;After soft seal wear out failure, valve seat support and the surface of flashboard 4 form hard sealing, remain to reach well
Sealing effectiveness, this soft or hard dual-seal makes valve seal performance relatively reliable, extends valve service life.
Various modifications to embodiment will be apparent for those skilled in the art, determine herein
The General Principle of justice can in other embodiments be realized in the case of without departing from spirit or scope of the present utility model.Cause
This, this utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The most wide scope consistent with features of novelty.
