Abstract
The utility model relates to valve technology field, especially a kind of linkage structure of stop valve inside.A linkage structure for stop valve inside, comprises flap and valve rod, and described flap is vertically connected with valve rod, and flap and valve rod joint are equipped with ball, are provided with flap pad bottom flap, and the bottom of flap pad is provided with gland pad.The utility model open and close time flap and valve body sealing surface between without relative sliding, thus wearing and tearing with abrade all not serious, good seal performance, long service life.
Description
Technical field
The utility model relates to valve technology field, especially a kind of linkage structure of stop valve inside.
Background technique
Stop valve, also known as pipe valve valve, belongs to forced seal formula valve, so when valve closing, must apply pressure, do not leak with forced seal face to flap.When medium is by when entering valve below flap, the resistance overcome required for steering force, be the frictional force of valve rod and filler and the thrust produced by the pressure of medium, the power of the force rate valve opening door of closing valve is large, so the diameter of valve rod wants large, otherwise the fault of valve rod bending can be there is.The open-shut device of stop valve is the flap of stopper, and in plane or the extra large conical surface above sealing, flap is along the center line moving linearly of valve seat.The valve rod of such valve open or shutoff stroke relatively short, and there is cutting function very reliably, again due to the change of valve seat port and the stroke direct proportionality of flap, be very suitable for the adjustment to flow.
Model utility content
The technical problems to be solved in the utility model is: based on the problems referred to above, provides a kind of linkage structure of stop valve inside.
The utility model solves the technological scheme that its technical problem adopts: a kind of linkage structure of stop valve inside, comprise flap and valve rod, described flap is vertically connected with valve rod, flap and valve rod joint are equipped with ball, be provided with flap pad bottom flap, the bottom of flap pad is provided with gland pad.
Further, described valve rod and valve body contact portion arrange sealing gasket.
The beneficial effects of the utility model are: the utility model open and close time flap and valve body sealing surface between without relative sliding, thus wearing and tearing with abrade all not serious, good seal performance, long service life.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure: 1. flap, 2. valve rod, 3. ball, 4. flap pad, 5. gland pad, 6. sealing gasket.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of linkage structure of stop valve inside, comprises flap 1 and valve rod 2, flap 1 is vertically connected with valve rod 2, flap 1 and valve rod 2 joint are equipped with ball 3, are provided with flap pad 4 bottom flap 1, and the bottom of flap pad 4 is provided with gland pad 5.
Further, valve rod 2 and valve body contact portion arrange sealing gasket 6.Sealing surface is not easy to wear and abrade, good airproof performance.
Pipeline is the used time just, and inner foul is more, can open, utilize the flow at high speed of medium by micro-for stop valve, washed away, then close (can not close soon, suddenly close, in case residual impurity crushes sealing surface) gently, again open, so repeatedly, wash down foul, then drop into normal work.
Often open stop valve, sealing surface may be stained with foul, also washed away totally with said method during closedown, then formally close tight.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
