Abstract

The invention relates to the technical field of valves, in particular to a connecting structure in a stop valve. The connecting structure in the stop valve comprises a valve flap and a valve rod. The valve rod is perpendicularly connected to the valve flap. Balls are arranged at a connecting part of the valve flap and the valve rod in a matched manner. A valve flap gasket is arranged at the bottom of the valve flap. A gland gasket is arranged at the bottom of the valve flap gasket. In the opening and closing processes, the sealing faces of the valve flap and a valve body are free of relative sliding, so that abrasion and scratches are not serious, the sealing performance is good, and service life is long.

Description

A kind of linkage structure of stop valve inside
Technical field
The present invention 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.
Summary of the invention
The technical problem to be solved in the present invention is: based on the problems referred to above, the invention provides a kind of linkage structure of stop valve inside.
The technical solution adopted for the present invention to solve the technical problems is: the linkage structure providing a kind 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 invention has the beneficial effects as follows: when the present invention opens and closes between flap and valve body sealing surface without relative sliding, thus wearing and tearing with scratch all not serious, good seal performance, long service life.
Accompanying drawing explanation
Below in conjunction with accompanying drawing embodiment, the present invention is further described.
Fig. 1 is structural representation of the present invention.
In figure: 1. flap, 2. valve rod, 3. ball, 4. flap pad, 5. gland pad, 6. sealing gasket.
Embodiment
The invention will be further described in conjunction with specific embodiments now, and following examples are intended to the present invention instead of limitation of the invention further are described.
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 invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to right.
