Abstract
A kind of Multifunctional stop valve, including hollow cylindrical valve body, upper valve body is vertically connected with the valve body, lower valve body, the upper valve body, lower valve body is hollow cylindrical and central axes, upper valve body, lower valve body inwall is provided with internal thread, it is placed in externally threaded hollow cylindrical flap in upper valve body, flap length is more than valve body diameter of section, flap upper end is fixedly connected with valve rod, flap side wall sets through hole, flap sets dividing plate in the axial direction, upper valve body upper end sets bonnet, valve rod through bonnet and is connected with handle in its end, lower valve body lower end sets bottom flange.By setting through hole in hollow cylindrical flap side wall, flap sets dividing plate in the axial direction, blocked or filtering function so that the stop valve possesses, because fluid flow direction is linear, fluid will not produce resistance in flowing, the impact wear to valve interior wall is reduced, the service life of stop valve is extended.
Description
Technical field
The utility model is related to valve body technical field, and in particular to a kind of Multifunctional stop valve.
Background technology
Stop valve is also known as pipe valve valve, belongs to forced seal formula valve, so when valve is closed, it is necessary to applies to flap and presses
Power, is not leaked with forced seal face.When medium below flap by entering valve, the resistance overcome required for operating physical force, is valve
The frictional force of bar and filler with as the thrust produced by the pressure of medium, the power of closing valve is bigger than the power of valve opening door, so valve rod
Diameter it is big, otherwise can occur the failure of valve rod bending.It is divided into three kinds by connected mode：Flange connection, screwed connection, welding
Connection.After the valve of self sealss occurs, the medium flow direction of stop valve just changes by entering valve pocket above flap, at this moment in medium pressure
Under power effect, the power of closing valve is small, and the power of valve opening door is big, and the diameter of valve rod can be reduced correspondingly.Meanwhile, in medium effect
Under, the valve of this form is also tighter.China's valve " three change to " once provided, the flow direction of stop valve, without exception using from upper
Under.When stop valve is opened, the Lift of flap, flows have reached maximum when being the 25%~30% of nominal diameter, represent valve
Door reaches fully open position.So the fully open position of stop valve, should be determined by the stroke of flap.
Existing stop valve can only realize cutoff function, unitary function, while current trend is bending in valve body, this can be produced
Raw larger fluid resistance, is unfavorable for flow of fluid, can produce abrasion to valve body for a long time, cause sealing effectiveness to be deteriorated, may
Disclosure risk can be produced.
Utility model content
Technical problem to be solved in the utility model is to overcome existing technological deficiency there is provided the multi-functional cut-off of one kind
Valve.
Technical problem to be solved in the utility model is realized using following technical scheme：
A kind of Multifunctional stop valve, including hollow cylindrical valve body, valve body one end are entrance point, and relative with entrance point is
Mouth end, upper valve body, lower valve body are vertically connected with the valve body, and the upper valve body, lower valve body are hollow cylindrical and central shaft
Line is overlapped, and upper valve body, lower valve body and valve body shape, and upper valve body, lower valve body inwall are provided with internal thread, with externally threaded
Hollow cylindrical flap is placed in upper valve body, and flap length is more than valve body diameter of section, and flap upper end is fixedly connected with valve rod, valve
Valve side wall sets through hole, and flap sets dividing plate in the axial direction, and upper valve body upper end sets bonnet, and valve rod is through bonnet and at it
End is connected with handle, and lower valve body lower end sets bottom flange, sealed lower valve body lower end by bottom flange.
The dividing plate selects sealing plate or filter, the upper valve body, lower valve body section radius and valve body section radius phase
Deng.
Sealing gasket is set on the bottom flange, and the upper valve body upper surface sets in annular groove, the annular groove and put
Put sealing ring.
The beneficial effects of the utility model are：By setting through hole in hollow cylindrical flap side wall, flap is along axis side
To dividing plate is set, blocked or filtering function so that the stop valve possesses, because fluid flow direction is linear, fluid
Resistance will not be produced in flowing, the impact wear to valve interior wall is reduced, extends the service life of stop valve.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model；
Fig. 2 is Fig. 1 along A-A faces sectional view.
Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
As shown in Figure 1-2, a kind of Multifunctional stop valve, including hollow cylindrical valve body 1, one end of valve body 1 are entrance point 2,

Hollow-cylindrical and central axes, upper valve body 4, lower valve body 10 can be integrally formed with valve body 1,10 sections of upper valve body 4, lower valve body
Radius surface is equal with the section radius of valve body 1, and upper valve body 4, the inwall of lower valve body 10 are provided with internal thread, with externally threaded hollow circle
Cylindricality flap 5 is placed in upper valve body 4, and the length of flap 5 is more than the diameter of section of valve body 1, and the upper end of flap 5 is fixedly connected with valve rod 6, valve
The side wall of valve 5 sets through hole 14, and flap 5 sets dividing plate 7 in the axial direction, and dividing plate 7 is selected on sealing plate or filter, upper valve body 4
End sets bonnet, 12, and valve rod 6 is through bonnet 12 and handle 8 is connected with its end, and the lower end of lower valve body 10 sets bottom flange 9,
The lower end of lower valve body 10 is sealed by bottom flange 9, is set on bottom flange 9 and annular groove 11 is set on sealing gasket 13, upper valve body 4,
Sealing ring is placed in annular groove 11 to seal bonnet, 12 with upper valve body 4.
