Description
Technical field
This utility model relates to a kind of valve, specifically a kind of novel cutoff valve.
Background technology
Stop valve, also known as pipe valve valve, belongs to forced seal formula valve, so when valve closing, it is necessary to apply pressure to flap
Power, does not leaks with forced seal face.When medium is by when entering valve below flap, and the resistance overcome required for operating physical force, is valve
The frictional force of bar and filler is with by thrust produced by the pressure of medium, and the power of the force rate valve opening door of closing valve is big, so valve rod
Diameter want big, the fault of valve rod bending otherwise can occur.It is divided into three kinds: Flange joint, screwed connection, welding by connected mode
Connect.After self-packing valve occurs, the medium of stop valve flows to just change by entering valve pocket above flap, at this moment in medium pressure
Under power effect, the power of closing valve is little, and the power of valve opening door is big, and the diameter of valve rod can correspondingly reduce.Meanwhile, in medium effect
Under, the valve of this form is the tightest.But existing stop valve is when opening, bigger torsion is needed to overcome hydraulic pressure,
In use handwheel uses inconvenience, impact safety in production.
Utility model content
The purpose of this utility model is that providing a kind of improves production efficiency, it is possible to the stop valve easily quickly opened, with
The problem solving to propose in above-mentioned background technology.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of novel cutoff valve, including valve body, valve body is installed with valve gap, and valve gap seals installation valve rod spiral shell co-axially over
Mother, described valve stem nut top is provided with handwheel, and valve rod extend in valve body after valve stem nut, valve gap, and valve rod lower end connects
Having flap, the lower surface of flap is provided with sealing ring, and sealing ring coordinates with the sealing surface of seat in valve body, is provided with on described handwheel
For shaking the rocking bar of handwheel, rocking bar is arranged straight up；The bottom of described valve rod is arranged with spring, and the upper end of spring is fixed on
On valve gap, lower end is fixed on flap.
Further: spring elongation when described flap is positioned at bottom.
Further: described rocking bar is by the fixing axle of inner side and is set in fixing outer shaft sleeve cylinder and constitutes, and sleeve is with fixing
Steel ball it is provided with between axle.
Further: the thickness of described sealing ring is 3～6mm.
Further: a length of the 50 of described rocking bar～80mm.
Compared with prior art, the beneficial effects of the utility model are: this utility model is by the handwheel of stop valve
Rocking bar is installed, is more convenient for operator's operation to handwheel, and then person convenient to operate eliminates life by operating this stop valve
Danger potential on product, and improve the efficiency produced；Spring is installed on valve rod and flap, alleviates the pressure that rotation valve rod produces
Power, is convenient for people to easily quickly open valve.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of novel cutoff valve.
In figure: 1-valve rod, 2-valve stem nut, 3-handwheel, 4-valve gap, 5-flap, 6-valve body, 7-sealing ring, 8-rocking bar, 9-
Spring.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Refer to figure, in this utility model embodiment, a kind of novel cutoff valve, including valve body 6, valve body 6 is installed with valve
Lid 4, valve gap 4 seals installation valve stem nut 2 co-axially over, and described valve stem nut 2 top is provided with handwheel 3, and valve rod 1 is through valve rod spiral shell
Extending in valve body 6 after mother 2, valve gap 4, valve rod 1 lower end connects has flap 5, the lower surface of flap 5 to be provided with sealing ring 7, sealing ring
The thickness of 7 is 3～6mm, and sealing ring 7 coordinates with the sealing surface of seat in valve body 6, it is achieved the cut-off effect of valve, at described hands
Wheel 3 is provided with the rocking bar 8 for shaking handwheel 3, and rocking bar 8 becomes and arranges straight up, a length of the 50 of rocking bar 8～80mm,
Rocking bar 8 is by the fixing axle of inner side and is set in fixing outer shaft sleeve cylinder and constitutes, and is provided with steel ball, makes sleeve between sleeve and fixing axle
Around solid fixed-axis rotation, due to the setting of rocking bar 8, it is more convenient for operator's operation to handwheel 3, and then person convenient to operate passes through
Operate this stop valve and eliminate production the most potential upper danger, and improve the efficiency produced；The bottom of described valve rod 1 is arranged with bullet
Spring 9, the upper end of spring 9 is fixed on valve gap 4, and lower end is fixed on flap 5, rotates handwheel 3, makes flap 5 move down and seal
Time, when flap 5 is positioned at bottom, spring 9 stretches, and when valve opened by needs, rotates handwheel 3, by valve under the pulling force of spring 9
Lobe 5 pulls up, and alleviates the pressure that rotation valve rod 1 produces, facilitates stop valve to open.
This utility model, by installing rocking bar 8 on the handwheel 3 of stop valve, is more convenient for the operator behaviour to handwheel 3
Make, and then person convenient to operate eliminates production the most potential upper danger by operating this stop valve, and improve the efficiency produced；Valve
Spring 9 is installed on bar 1 and flap 5, alleviates the pressure that rotation valve rod 1 produces, be convenient for people to easily quickly open valve.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this practicality in other specific forms new
Type.Therefore, no matter from the point of view of which point, all should regard embodiment as exemplary, and be nonrestrictive, this practicality is new
The scope of type is limited by claims rather than described above, it is intended that by the containing of equivalency in claim that fall
All changes in justice and scope are included in this utility model.Should not be considered as any reference in claim limiting
Involved claim.
Although moreover, it will be appreciated that this specification is been described by according to embodiment, but the most each embodiment only wraps
Containing an independent technical scheme, this narrating mode of description is only that for clarity sake those skilled in the art should
Description can also be formed those skilled in the art through appropriately combined as an entirety, the technical scheme in each embodiment
May be appreciated other embodiments.
