Embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating the present invention
Technical scheme, and can not be limited the scope of the invention with this.
As illustrated in fig. 1 and 2, a kind of stop valve for being easy to adjust flow, including：
Valve body 10, there is a runner 10a flowed through for medium；
Flap 20, it is movably arranged in valve body 10 to block or turn on runner 10a；
Valve rod 30, it is connected to flap 20；
Bonnet 40, valve body 10 is connected to so that valve rod 30 is slidably installed；
Handwheel 50, valve rod 30 is connected to for for operating；
Nut 60, it is connected to bonnet 40 and is threadedly coupled with the composition of valve rod 30；
Valve pocket 70, it is installed in valve body 10；
Torsion spring 80, it is installed in valve body 10；
Rod set 90, bonnet 40 and nut 60 are connected to, and are sleeved on valve rod 30 and the periphery of nut 60.
Valve pocket 70 has the intercommunicating pore 70a that can connect runner 10a, and flap 20 can be blocked or opened in moving process
Intercommunicating pore 70a is so that runner 10a is in blocks or conducting state.
Connection, the notch 70b of the horizontal insertion valve pocket 70 of the other end are formed in the cross-drilled hole of the horizontal insertion valve rod 30 in one end of torsion spring 80
Middle to form connection, valve rod 30 can make torsion spring 80 produce elastic potential energy when rotating.The mounting means of torsion spring 80 can be：1. in valve
Door closure state keeps normality, and keeps deforming in valve opening state；2. keep deforming in valve-closed state, and in valve
Opening keeps normality.First way can make valve obtain the power-assisted of torsion spring 80 when being adjusted from unlatching to closing, from
And mitigate drop Flow-rate adjustment burden.The second way obtains the power-assisted of torsion spring 80 when valve can be made to be adjusted from closing to unlatching,
So as to mitigate flow increasing regulation burden.
There is handwheel 50 the annulus 50a extended in the axial direction, annulus 50a to be arranged at nut 60 and rod set 90
Between and formed with both and be slidably connected and valve rod 30 stretches out in the inside for being partially housed in both of valve body 10.So cause
The annulus 50a of handwheel 50 forms all coverings with rod set 90 to the exposed parts of valve rod 30, avoids the exposure of valve rod 30, from
External influence is fundamentally prevented.
Preferably, the valve seat formed along the circumferentially extending of flap 20 is additionally provided with valve body 10 on the path of medium
10b, the lower end of flap 20 have the circular conical surface that sealing cooperation can be formed with valve seat 10b；Flap 20 open simultaneously valve seat 10b and
During intercommunicating pore 70a, runner 10a is in the conduction state.Flap 20 can so cooperatively formed with valve pocket 70 and valve seat 10b tends to
The flow channels of linear gradient, so as to meet the requirement for being easy to Flow-rate adjustment.
Preferably, grommet 100 is additionally provided with valve seat 10b, circular conical surface can form sealing with grommet 100 and match somebody with somebody
Close.So can when the sealing of grommet 100 is deteriorated in time, efficiently change, avoid flap 20 and valve seat 10b directly contact and
Produce permanent abrasion..
Preferably, airtight and watertight padding 110 is provided between valve rod 30 and bonnet 40.The close of valve can so be improved
Feng Xing, the outside seepage of medium is avoided, while avoid external substance from entering valve body 10.
Preferably, rod set 90 has inner convex platform 90a, and inner convex platform 90a side and bonnet 40 form location and installation,
Opposite side forms location and installation with nut 60.Efficiently it is installed in place when rod set 90 is installed with bonnet 40.
Preferably, annulus 50a has outer lug boss, and outer lug boss can form end face limit with one end of valve pocket 70
Position.So valve rod 30 can be made to receive limitation in the movement of axis direction.
Preferably, torsion spring 80 is set on valve rod 30.The fixation that torsion spring 80 can so more consolidated,
Prevent the deformation for deviateing axial direction.
Preferably, there is flap 20 axially arranged pressure guide hole 20a, pressure guide hole 20a can be delivered to medium
The upper surface of flap 20.Can so realize that flap flattens weighing apparatus about 20, avoid because pressure difference is excessive and caused by switching torque it is big
The defects of.
Preferably, annulus 50a is formed with valve pocket 70 and is threadedly coupled.
Preferably, anti-corrosion lining is provided with valve body 10.High temperature can be so applied to or there is certain soda acid
The medium of degree.
It is worth noting that, in this patent, in addition to the feature that embodiment is recorded, wine dispenser possessed further feature is equal
Disclosed by other prior arts, these features are not the improvement place of this patent, therefore are not further detailed.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, some improvement and deformation can also be made, these are improved and deformation
Also it should be regarded as protection scope of the present invention.
