Specific embodiment
The preferred embodiment of the utility model is illustrated below in conjunction with attached drawing, it should be understood that described herein excellent
Embodiment is selected to be only used for describing and explaining the present invention, is not used to limit the utility model.
Embodiment 1
As shown in Figure 1, the utility model provides a kind of anti-leak cut-off copper valve, including valve body 1,1 side of valve body is equipped with
Inlet 2, inlet 2 connect valve port 3, and valve port 3 connects liquid outlet 4 with liquid flow path direction, and 1 middle part of valve body penetrates a valve rod 5, valve
5 bottom of bar connects spool 6, and 6 surrounding of spool and bottom are equipped with sealing ring 7, and 1 top of valve body is equipped with valve deck 8, and valve deck 8 and valve body 1 connect
There are gasket 9 and corresponding mounting hole 10 in the place of connecing, and 10 top of mounting hole is equipped with bolt 11, and 8 bottom of valve deck is equipped with Packing seat 12,
12 top bonding pad 13 of Packing seat, 13 top of filler are equipped with elastomer block 14, and 14 top of elastomer block is equipped with installation lid 15, installation lid
15 inner walls are equipped with sealing ring 16 with 5 contact position of valve rod, and 5 top of valve rod is equipped with handle 17.
Sealing ring 7 is spill and is sleeved on spool 6.When valve rod 5 moves down, the sealing ring 7 being sleeved on spool 6 can push up
On valve port, spool 6 pushes up tighter, and sealing ring 7 is bigger to 3 extruding force of valve port, and sealing performance is better, i.e., valve port 3 is closed, liquid stream
Cut-off.Portion cross-sectional area is more than 3 cross-sectional area of valve port on spool 6, and 6 bottom area of spool is less than 3 area of valve port, you can more
The good sealing ring 7 that makes is extruded on valve port 3, and shut-off valve is made to shut off, and performance is more preferable, and filler 13 is to be new without asbestos high molecular material
The airtight and watertight padding of synthesis, soft sealed packing are commonly called as pureed soft packing, are a kind of new sealings without asbestos synthesis of polymer material
Filler, appearance such as clay shape have special plasticity.Due to the effect of the special material of soft packing, the frictional heat of generation is very
It is small.The effect of macromolecule barrier ensure that non-leakage between medium between filler.Therefore, this kind of filler is a kind of plastic
, the sealing material sealing ring 16 of low friction filler be rubber material, rubber not only has elasticity, and sealing performance is also preferable.
Concrete operating principle：Liquid is flowed into from inlet 2, is flowed out by valve port 3 from liquid outlet 4, when need to liquid stream cut
When only, handle 17 is rotated, moves down valve rod 5, the spool 6 of 5 bottom of valve rod connection withstands on sealing ring 7 on valve port 3, with spool
The pressure of 6 pairs of sealing rings 7 is increasing, and the sealing ring 7 of rubber material squeezes completely to be fitted on valve port 3, closes shut-off valve,
Liquid stops flowing, when needing to open shut-off valve, negative direction rotation handle 17.Valve rod 5 between valve deck 8 because have time
Gap is sealed it using soft sealed packing, the work of macromolecule barrier between the very small and filler of soft sealed packing friction
It is non-leakage between medium with ensure that.The spilling of liquid stream is effectively blocked, meanwhile, the rubber seal ring 16 on valve rod 5 equally rises
To the effect for blocking liquid leakage.
The advantageous effect that the utility model is reached is：The device uses two kinds of sealing material sealing valves of filler and sealing ring
Gap at bar.Wherein filler is soft sealed packing, is a kind of new airtight and watertight padding without asbestos synthesis of polymer material, has
The features such as plastic, low friction, sealing ring plays the role of auxiliary seal for rubber material.The shut-off valve sealing effect is good, uses
Long lifespan, shut-off valve have a safety feature.
Finally it should be noted that：The above descriptions are merely preferred embodiments of the present invention, is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it can still modify to the technical solution recorded in foregoing embodiments or to which part technical characteristic
Carry out equivalent replacement.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
