Description
Technical field
This utility model relates to valve class, particularly to a kind of forged steel gate valve.
Background technology
Gate valve is an opening and closing element flashboard, gate valve during regulation can standard-sized sheet and fully closed, thus regulate the opening and closing of pipeline.The flashboard of gate valve acts as linear motion up and down with valve rod one and realizes opening and closing, and valve rod is screw rod, it is possible to by rotating thus the axially-movable of regulating valve stem.
Owing to valve plate can be impacted by liquid, thus valve rod would tend to occur the situation of slow-action lifting when, goes down to easily cause the gap of junction for a long time so that the situation of leakage occurs in valve.
Utility model content
The deficiency existed for prior art, the purpose of this utility model is the forged steel gate valve providing the lifting of a kind of valve rod stable.
Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of forged steel gate valve, including valve body, valve gap, the valve rod for regulation valve body opening and closing it is equipped with on described valve gap, described valve gap is provided with fixed mount, described valve rod includes thread segment above, is positioned at the bright finish section of lower section, the thread segment of described valve rod and fixed mount threaded engagement, in the bright finish section of described valve rod, clamping is provided with a pair holding piece, realize mutually clamping by screw between described holding piece, and described holding piece is clamped between bright finish section and the fixed mount of valve rod.
Pass through technique scheme, holding piece can be clamped in above valve rod and fixed mount, like this valve rod is fixed by holding piece, the smooth of binding face is ensured with the structure of valve rod bright finish section laminating, it can be made can to remain vertical state during lifting, it is ensured that it is not easy the situation occurring rocking.
This utility model is further arranged to: described holding piece is symmetrical set, and described holding piece be provided with valve rod bright finish section laminating arcwall face, for the clamping block conflicted with fixed mount.
By technique scheme, the structure of arcwall face can maximize with the contact area of valve rod, and valve lever clamp can be kept steady fixed by holding piece, and valve rod can be clamped by chucking power along arcwall face, it is ensured that valve rod does not haves situation about rocking in lifting process.
This utility model is further arranged to: be fixed with the wear-resistant block being made up of graphitic steel on described holding piece by screw, and arcwall face is positioned at inside wear-resistant block.
By technique scheme, the structure of wear-resistant block can make it will not scratch valve rod in relative fricting movement, also is able to ensure the smoothness of valve rod simultaneously.And wear-resistant block is fixed by screw, this makes it possible to ensure that wear-resistant block is after loss, it is possible to more convenient it is replaced.
This utility model is further arranged to: be provided with the block rubber for fitting with fixed mount inside described clamping block.
By technique scheme, the structure of block rubber can increase the frictional force of clamping block and fixed mount, it is ensured that valve rod, during lifting, will not be said that grip block drives skew, thus the situation causing clamping unstable occurs.
This utility model is further arranged to: described clamping block is provided with the draw-in groove plugged together for block rubber.
By technique scheme, the replacing that the structure of draw-in groove realizes block rubber is convenient, also is able to be replaced it timely after block rubber is aging.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
As shown in Figure 1, a kind of forged steel gate valve, including valve body 1, valve gap 2, the valve rod 3 for regulation valve body 1 opening and closing it is equipped with on valve gap 2, valve gap 2 is provided with fixed mount 21, valve rod 3 includes thread segment 31 above, it is positioned at the bright finish section 32 of lower section, thread segment 31 and fixed mount 21 threaded engagement of valve rod 3, valve rod 3 is arranged above with the handle of circle, people are needs carry out opening and closing regulation to valve when, have only to helical rotation valve rod 3, the thread segment 31 of valve rod 3 and fixed mount 21 threaded engagement, so valve rod 3 just can slide up and down along with spiral, ensure that it can be stablized and effectively valve is adjusted displacement.
Wherein, in the bright finish section 32 outside valve rod 3, clamping is provided with a pair holding piece 4, in holding piece 4 structure symmetrically, realizes mutually gripping by screw, and the bright finish section 32 of valve rod 3 is all clamped with fixed mount 21 by holding piece 4 between holding piece 4.Holding piece 4 can be clamped in above valve rod 3 and fixed mount 21, and like this valve rod 3 is fixed by holding piece 4, ensures the smooth of binding face with the structure of valve rod 3 bright finish section 32 laminating, it is ensured that valve rod 3 does not haves situation about rocking in lifting process.
Such as Fig. 2, holding piece 4 is fixed with by screw the wear-resistant block 41 being made up of graphitic steel, inside wear-resistant block 41, is provided with the arcwall face for the laminating of valve rod 3 bright finish section 32.The structure of arcwall face can maximize with the contact area of valve rod 3, and valve rod 3 can be clamped stable by holding piece 4, and the structure of wear-resistant block 41 can make it will not scratch valve rod 3 in relative fricting movement, also is able to ensure the smoothness of valve rod 3 simultaneously.And wear-resistant block 41 is fixed by screw, this makes it possible to ensure that wear-resistant block 41 is after loss, it is possible to more convenient it is replaced.And holding piece 4 is provided with the clamping block 42 for conflicting with fixed mount 21, clamping block 42 quantity is two, and lay respectively at the right and left of holding piece 4, the block rubber for fitting it is provided with fixed mount 21 inside clamping block 42, clamping block 42 is provided with draw-in groove 421, block rubber plugs together in draw-in groove 421, the replacing that the structure of draw-in groove 421 realizes block rubber is convenient, it also is able to timely it is replaced after block rubber is aging, the structure of block rubber can increase the frictional force of clamping block 42 and fixed mount 21, it is ensured that valve rod 3 is during lifting.
The above is only exemplary embodiment of the present utility model, and not for limiting protection domain of the present utility model, protection domain of the present utility model is determined by appended claim.
