Specific implementation mode
The utility model is further illustrated with reference to the accompanying drawings and examples：The mechanical dehydration device as shown in Fig. 1,5
With cutting water valve, including valve body 3, valve deck 2, valve rod 6 and stuffing nut.
If the bottom of Fig. 2, the valve body 3 are equipped with water inlet 34, side is equipped with central shaft and water inlet central axis
Water outlet 35, water inlet, water outlet are connected to the column valve chamber 36 of open top, and the top of valve body is equipped with external screw thread.Valve body 3
Medial surface 33 be cylindrical surface, the water outlet 35 of valve body side is located on valve body madial wall 33.About 6 valve rod is oriented in valve chamber
It moves up and down, cooperation is close, effectively reduces sealing offset, is beneficial to seal.
Such as Fig. 4, the valve rod 6 is that diameter up-small and down-big two sections is cylindric, and hypomere is just to be embedded in the valve chamber 36
Spool 63, epimere are the connecting rod 62 that top is equipped with blind hole 61, and the outer end of the blind hole 61 is equipped with internal thread, for connecting floating ball.
Such as Fig. 2, outlet pipe 4 is fixed with around water outlet 35 is closed, the outer end of the outlet pipe 4 is equipped with internal thread, uses
In airtight connection pipeline.
Such as Fig. 3, up and down, valve deck 2 is installed on above valve body, and lower part is equipped with and body top at the middle part of the valve deck 2
External screw thread engagement internal thread, top is equipped with external screw thread, for being connect with stuffing nut 1.
Such as Fig. 5, up and down, lower part with the external screw thread of bonnet lower equipped in engaging at the middle part of the stuffing nut 1
Threaded upper portion opening can just be embedded in the connecting rod 62.Built-in 2 O-ring seals in valve deck top are filled out as sealed valve stem filler
Material nut adjusts the sealing of valve rod and valve body by being threaded onto on valve upper part of the cover external screw thread.
If the stuffing nut 1 is stretched out at the top of Fig. 1, valve rod 6, between connecting rod and valve deck, the top of connecting rod and valve chamber
Between be equipped with O-ring seals 5, the bottom in valve chamber also is provided with O-ring seals 5.Distinguish the top and bottom of the valve chamber
Equipped with upper grooves 31 and bottom groove 32, the shape of upper grooves 31 and bottom groove 32 and 5 phase interworking of the O-ring seals
Set, makes the O-ring seals 5 of corresponding position be partially embedded into upper grooves 31 or bottom groove 32.
The O-ring seals 5 that valve body 3 is inlayed under the effect of floating ball compression weight with bottom groove in valve body 32 are in close contact really
Confidential letter.
Therefore, floating ball floats up and down in the medium to be moved up and down with ovable valve stem 6.
Water hour, the O-ring seals 5 that valve body 3 is inlayed under the effect of floating ball compression weight with bottom groove in valve body 32
Close contact ensures to seal.
63 side of stem lower portion spool and the 3 excessively cooperation of madial wall 33 of valve body, when valve rod 6 is in 3 bottom of valve body, valve rod
The water outlet 35 of 4 inner end of valve body side outlet pipe can be completely covered in spool 63 side in lower part, cut water valve at this time and be in pass completely
Close shape.When valve rod 6 is in 3 top of valve body, 63 side of stem lower portion spool can completely offset from water outlet 35, cut water valve at this time
In fully open state.Therefore, it is exactly the change in location for utilizing stem lower portion spool 63 vertical in valve body 3 originally to cut water valve,
Water valve aperture is cut to change.Sealing is contacted with the extruding of O-ring seals 5 and close using 63 lower face of stem lower portion spool.
When in use, medium unicom of the import of water valve directly with bottom in dehydrator tank is cut, water outlet passes through internal thread
It is connect with the outlet pipe of pipeline.Floating ball in dehydrator is connected by bottom for the internal thread of externally threaded sunpender and valve stem top
It connects, passes through position of the control valve rod in valve body of floating up and down of floating ball.In valve body, only two above and below the spool of stem lower portion
End is contacted with O-ring seals by face.
Using the cooperation of the spool and side exit of stem lower portion come control valve aperture when originally cutting water valve.Specifically,
When being water entirely in drain sump, floating ball floats in water, and valve rod and then moves up, until spool upper end and valve body internal upper part recess-mounted
O-ring seals contact.Cut water valve standard-sized sheet at this time, the water of bottom enters valve body by the import of body base in drain sump, from
The water outlet of side is discharged.When being oil entirely in drain sump, floating ball sinks in the oil, and valve rod and then moves down, until spool bottom end with
The O-ring seals contact that bottom groove is inlayed in valve body.Cut that water valve is fully closed at this time, in drain sump the water of bottom be blocked it is anhydrous from
The outlet of side is discharged.It is oil when lower part is portion waterborne in drain sump, when floating ball is in half floating half heavy state, valve rod is followed up and down
Mobile, the spool bottom sides of stem lower portion change with the exit aperture size of valve body side.The water of dehydrator bottom is logical
The gap for crossing valve body and import enters water outlet, and drain discharge also changes.
