Technical field
The present invention relates to a kind of valve rifle for high-pressure cleaning appliance, valve rifle is for being discharged cleaning liquid, the valve rifle tool
There are the valve of shell and setting in the housing, the valve that there is closure body, the closure body to be arranged on valve tappet and close
It is closely sticked in position on valve seat and closure body can be pivotally supported at bearing by that can surround the first pivot axis
The rotation of trip lever on position overcomes the pressure of cleaning liquid being applied on closure body to move to beating of being spaced apart with valve seat
In open position, wherein trip lever occupies resting position in the closed position of closure body and accounted in the open position of closure body
It is mechanically coupled with valve tappet according to releasing position and via the coupling bar that the second pivot axis is pivotally supported can be surrounded, wherein
The pivoting action of trip lever along the connecting link that guide rail moves via can be transmitted on coupling bar and guide rail
Road has first end section, intermediate section and the second end section.
Background technology
The discharge of cleaning liquid can be controlled by this valve tappet, cleaning liquid is placed in pressure by high-pressure cleaning appliance
Under.There is valve tappet valve, the valve to have entrance and exit.Pressure hose can be for example connected on entrance, and in the upper example in outlet
It such as may be coupled to spray gun.Valve tappet via pressure hose by the cleaning liquid of conveying pressure-bearing, and can be by liquid via spray gun
Body is towards object.In order to control liquid discharge, user is possible to trip lever being pivoted in releasing position from resting position.It loosens
Bar can be pivotally supported at around the first pivot axis in supporting portion thus.Via coupling bar, trip lever and valve tappet machinery
The closure body of valve is arranged in connection on valve tappet.Valve tappet can one-piece be connect with pipe wall body, but relate to two
Individual component.Since closure body is closely against the closed position on valve seat, closure body can pass through the pivot of trip lever
It moves in the open position being spaced apart with valve seat, wherein closure body, which is transferred to from closed position in open position, overcomes cleaning solution
The pressure of body acted on closure body carries out.
The pivoting action of trip lever is transmitted to via that can surround the coupling bar that pivot axis is pivotally supported on valve tappet,
The closure body of valve is set on valve tappet.Pivoting action is transmitted to coupling bar from trip lever and is carried out via connecting link, the coupling ring
Section can be moved by the pivot of trip lever along guide rail.Guide rail has first end section, intermediate section and the
Two end sections.If trip lever is pivoted to from resting position in releasing position, connecting link is moved along guide rail, and
And this causes again, coupling bar also executes pivoting action and thus valve tappet is moved.
Other than the pressure of cleaning liquid, the power of the resetting spring of valve is typically applied to closure body, and the power ensures,
After carrying out liquid discharge, once user discharges trip lever, then closure body automatically occupies its closed position again.In order to beat
Therefore considerable power must be applied on closure body by valve opening.
A kind of valve rifle is disclosed in 1 389 495A1 of EP, wherein passing through such as lower section for operating force necessary to open valve
Formula reduces:Piston sticks on trip lever, and the pressure existing for valve seat upstream for cleaning liquid acts on the piston.The piston
It can move and hermetically support in the channel.
A kind of valve rifle is disclosed in WO 2015/086085A1, wherein trip lever is via two connecting links and coupling bar
Mechanical attachment, wherein the two connecting links successively connect the different sections of guide rail when trip lever moves pivotally
It touches.First connecting link has the spacing of bigger compared to pivot axis of second connecting link away from coupling bar in the case.
This has the following advantages that:When trip lever is transferred to releasing position from resting position, the lever ratio of coupling bar changes.It is shifting
First stage in, due to there are advantageous lever ratio so larger opening force can be applied on valve tappet, even
In the case where user only loads trip lever with smaller operating force, wherein the lever ratio example by the first connecting link with
Big spacing between the pivot axis of coupling bar obtains.Between big between the first connecting link and the pivotal axis of coupling bar
Away from causing, the small stroke of valve tappet can be only reached during the first stage of the pivoting action of trip lever, i.e. only valve tappet
Smaller mobile distance.The then connection between trip lever and coupling bar in the second stage of the pivoting action of trip lever
It connects and is carried out via the second connecting link, which has smaller spacing.Second
Connecing the smaller spacing of link causes, and when trip lever further pivots, can reach the larger mobile distance of valve tappet, make
Obtaining closure body can be transported to there is bigger spacing away from valve seat.
The connecting link successively used using two when trip lever is pivoted to from resting position in releasing position is therefore
So that valve rifle is easy to manipulate.However, this requires the expense in certain structure.
Invention content
The task of the present invention is improve valve rifle of the type mentioned at the beginning so that its with better simply structural texture and
Therefore it can in a simple manner decoupled be operated by user to open valve.
The task is solved according to the present invention in the following way in terms of such valve rifle:Connecting link is loosening
Bar from resting position rotation to releasing position in when can along first end section, then along intermediate section and next along
The second end section move, wherein first end section compared to intermediate section have relative to trip lever pivotal orientation compared with
Small gradient.
The pivotal orientation of trip lever is carried out along imaginary circular arc, and the midpoint of the circular arc corresponds to the supporting portion of trip lever
And the radius of the circular arc corresponds to contact site and trip lever in the first end section of connecting link and guide rail
Supporting portion between spacing.
In valve rifle according to the present invention, the mechanical attachment between trip lever and coupling bar is realized via connecting link,
The connecting link when trip lever is from resting position rotation to releasing position from the first end section of guide rail through
By intermediate section movement until the second end section of guide rail.Via connecting link and guide rail, the pivot of trip lever
Movement is transmitted on coupling bar, which again applies with opening force, under the action of the opening force, the arrangement of valve valve tappet
Closure body on valve tappet is moved to from closed position in open position.
The operating force that valve is spent, in valve rifle according to the present invention, the first of guide rail are opened in order to reduce user
Pivotal orientation of the end section compared to intermediate section relative to trip lever tilts smaller.First end section is relative to loosening
The smaller gradient of pivotal orientation of bar causes:Coupling bar in trip lever just from resting position rotation when only less change first
Its pivot position, that is to say, that the pivoting angle of trip lever changes only causes the small pivoting angle of coupling bar to change first.So
And the small pivoting angle of coupling bar changes the position change for also causing closure body so that even if closure body position change is small
When be also lifted away from valve seat and thus the pressure existing for valve seat upstream of cleaning liquid slightly declines.It is further put in trip lever
When going in releasing position, connecting link reaches the intermediate section of guide rail.Because intermediate section is compared to first end portion
Section has the stronger gradient of pivotal orientation relative to trip lever, so intermediate section is then relative to vacation referred to above
The circular arc thought more strongly tilts, this causes:Changed by the smaller pivoting angle of trip lever and the aobvious of coupling bar may be implemented
The pivoting angle of work changes and thus can also realize the significant position change of closure body.But strong position change is as follows
Time point occurs:The pressure existing for valve seat upstream of cleaning liquid has been substantially reduced at the time point so that can be utilized
Smaller power realizes the change of position.
The first end section of guide rail relative to trip lever pivotal orientation and thus relative to set forth above

Until the connecting link of contact guidance track can realize valve rifle in the case during the entire pivoting action of releasing position
Fairly simple structural texture.
Particularly advantageously, the second end section of guide rail has the pivot relative to trip lever compared to intermediate section
Turn the smaller gradient in direction.As has already been discussed, the pivotal orientation by the section of guide rail relative to trip lever
It tilts and is tilted thus relative to imaginary circular arc set forth above, the pivoting angle for being preset in trip lever changes and coupling bar
Pivoting angle change between relationship.Gradient is bigger, then the pivoting angle of coupling bar changes bigger, which changes
Become by the pivoting angle of trip lever to change and realize.Small gradient causes:The pivoting angle of trip lever changes only smaller
Ground influences the change of the pivoting angle of coupling bar.In addition, small gradient causes:The power base being applied to by coupling bar on trip lever
It is radially oriented relative to imaginary circular arc set forth above in sheet, that is to say, that bearing of the power generally toward trip lever
It is directed toward and is not roughly parallel to the pivotal orientation of trip lever in position.If the second end section of guide rail is relative to pine
The pivotal orientation of de- bar with small gradient, then cleans liquid with small gradient and thus relative to imaginary circular arc
And valve resetting spring the power acted in the open position of valve on closure body via coupling bar relative to imaginary circle
Arc passes to trip lever substantially along radial direction so that user only must spend small power that trip lever is maintained at release position
In setting.
Can design, the second end section of guide rail is parallel to the pivotal orientation of trip lever, i.e., with front institute
The imaginary circular arc illustrated is tangentially orientated.This orientation of the second end section can realize in the open position of valve via
Coupling bar is radially supported on trip lever by connecting link and the second end section relative to imaginary circular arc.It is loosening
The power applied by user in the releasing position of bar can be kept as especially small in the following way.One in the present invention is advantageous

Go out.At interval with valve chest 26, it is fixed with Spring holder 48 on the end regions 46 of valve tappet 44.In Spring holder
(the first back-moving spring 50 is sandwiched between 48 and valve chest 26, the resetting spring is to 44 spring loaded of valve tappet, in the spring force
Under the action of closure body 42 occupy closed position, closure body closely sticks on valve seat in a closed position.Pass through valve tappet
44 overcome the movement of the power of (the first back-moving spring 50, closure body 42 that can move in open position, close in the open position
Body is at regular intervals away from valve seat 40 and thus discharges the flow path between valve inlet 28 and valve outlet 30.
For operation valve 24, there is valve rifle 10 trip lever 52, the trip lever to join via coupling bar 54 and 44 machinery of valve tappet
It connects.Trip lever 52 is arranged in handle 56, which protrudes from shell area 22 backward.In an illustrated embodiment, it protects
Camber member 58 extends to the shell area 20 of front from the end regions 60 departing from shell area 22 backward of handle 56.It protects
Shield camber member 58, the shell area 18 in center and handle 56 are surrounded and are held into opening 62, and user, which can be entered with its finger gripping to this, to hold
Enter in opening.
Trip lever 52 can be supported on two shells around the first pivot axis 66 at supporting portion 64 in a manner of rotation
On shell 14,16.Handle 56 has handle opening 68 on its back side away from valve 24, and trip lever 52 is with operating surface 70 via handle
Hand opening is stretched from shell 12.Trip lever 52 is at it departing from the first pivot axis 66 and thereby departing from supporting portion 64
Connecting link 74 is carried on end side 72, which is configured to free to rotate in Fig. 1 and first embodiment shown in Fig. 2
Connection roller 76.
Trip lever 52 carries retaining pin 80 on its front side 78 departing from operating surface 70, and is fixed in the retaining pin
Two resetting springs 82, which is supported in retaining pin 80 and the other side is supported on the spring receiving portion 84 of shell 12
On.Reset force is applied on trip lever by second back-moving spring 82, the institute in trip lever rotation to Fig. 2 under the action of the reset force
In the resting position shown.
In the centrally disposed shell area 18 of coupling bar 54 and 86 rotation of the second pivot axis can be surrounded.Shown
Embodiment in, coupling bar is supported on valve chest 26.However coupling bar can also be supported on to rotation the shell half of shell 12
On shell 14,16.Second pivot axis 86 is parallel to 66 ground of the first pivot axis orientation.It is closely-spaced with the second pivot axis 86
Ground, coupling bar 54 have adjustable power loading element 90, power load member on its front end 88 departing from trip lever 52
Part sticks on the end of the stretching of slave valve chest 26 of valve tappet 44.Coupling bar 54 is on its rear end 92 towards trip lever 52
With the guide rail 94 towards trip lever 52, connection roller 76 is moved in 52 rotation of trip lever along the guide rail.
Guide rail 94 has first end section 96, intermediate section 98 and the second end section 100.Trip lever 52 in fig. 2
Shown in resting position, connection roller 76, which sticks in first end section 96 or away from end section 96, has small spacing.
The spacing can for example be less than 3mm.User is possible to grasp handle 56 with its hand, wherein the operating surface 70 of trip lever 52 reclines
On the ball of user.This for user give with ball by trip lever 52 from its in fig. 2 shown in rest position
Set overcome second back-moving spring 82 make land used forward in rotation to unshowned releasing position in this illustration.As long as connection rolling
There is small spacing away from end section 96 before son, then couples roller 76 and end is touched due to the pivoting action of trip lever 52
Section 96.The further pivoting action of trip lever 52 causes, and connection roller 76 is since first end section 96 via centre
Section 98 moves to the second end section 100.The pivoting action of trip lever 52 is transmitted via connection roller 76 and guide rail 94
Onto coupling bar 54 so that the coupling bar surrounds 86 rotation of the second pivot axis.This causes again:Valve tappet overcomes the first reset bullet
It moves to the reset force of spring 50 and thereby turns off body 42 and occupy its open position being spaced apart with valve seat 40.
The pivoting action of trip lever 52 is illustrated by imaginary circular arc 104 in fig. 2, and the radius of the circular arc is corresponding to as follows
Spacing, connection roller 76 have the spacing, and the circular arc in the contact site of first end section 96 away from supporting portion 64
Center is the supporting portion 64 of trip lever 52.
As in fig. 2 directly it can be seen that as, the only pivot slightly relative to trip lever 52 of first end section 96
Direction tilt and therefore relative to imaginary circular arc 102 tilt, and intermediate section 98 relative to trip lever pivotal orientation and
Select significantly larger thus relative to the gradient of imaginary circular arc 102.The gradient of the second end section 100 is again apparent small
The gradient possessed by pivotal orientation of the intermediate section 98 relative to trip lever 52.It especially can be designed as, the second end
Section 100 relative to the gradient of the pivotal orientation of trip lever 52 select with first end section 56 relative to trip lever 52
The gradient of pivotal orientation (imaginary circular arc 102) is equally big.
If trip lever 52 from its in fig. 2 shown in resting position setting in motion to its releasing position, coupling bar
54 pivoting angle position changes due to the small gradient that pivotal orientation of the first end section 96 away from trip lever 52 has, when
Connection roller 76 only slightly changes first when being moved along intermediate section 98, so as to then in the further rotation of trip lever into
The significant pivoting angle of row changes.If coupling roller 76 reaches the second end section 100, the pivot of the end of trip lever 52
Movement only causes the small pivoting angle of coupling bar 54 to change, this is because the second end section 100 is relative to trip lever 52
Pivotal orientation also has small gradient.
Once connection roller 76 is moved along the first end section 96 of guide rail 94, coupling bar 54 is implemented small
Pivoting angle change results in closure body 52 to be slightly lifted away from valve seat 40, to clean being pressed existing for 40 upstream of valve seat for liquid
Power reduces.Connection roller 76 then along the movement of the intermediate section 98 of guide rail 94 then result in coupling bar 54 strongly
Pivoting angle changes and thus leads to significant movement of the closure body 42 towards its open position.Therefore closure body 42 is released completely
Put valve seat 40 so that cleaning liquid can flow to valve outlet 30 from valve inlet 28.If coupling roller 76 reaches the second end portion
Section 100, then further move pivotally of trip lever 52 only also cause the small pivoting action of coupling bar 54 so that closure body
42 only also slightly move.
In the open position of closure body, connection roller 76 sticks in the second end section 100 of guide rail 94.It closes
Closure 42 is loaded with power towards its closed position by (the first back-moving spring 50 in the open position.In order to which closure body 42 is maintained at
In its open position, therefore closure body 42 must be loaded by coupling bar 54 with retentivity via valve tappet 44.Coupling bar 54 via
The second end section 100 and connection roller 76 of guide rail 94 are supported on trip lever 52.Trip lever 52 in the case by
54 loading force of coupling bar, the power are essentially radially orientated relative to imaginary circular arc 102.This allows user will be loose with small power
De- bar 52 is maintained in its releasing position, and closure body 42 occupies its open position in the releasing position.
If closure body 42 occupies its closed position again so that the flowing between valve inlet 28 and valve outlet 30 couples
It interrupts, then only needs thus, user discharges trip lever 52.Under the action of second back-moving spring 82, then trip lever 52 is put
Go to its in fig. 2 shown in resting position, wherein connection roller 76 is opened from the second end section 100 of guide rail 94
Begin to move to first end section 96 via intermediate section 98.
The first end section 96 and the second end section 100 of guide rail 94 have relative to the pivotal orientation of trip lever 52
The small gradient having makes user be easy to manipulate valve rifle 10.Valve rifle 10 can especially utilize smaller power to operate.
The second advantageous form of implementation of valve rifle according to the present invention is schematically shown in figure 3 and is generally set
There is reference numeral 150.Valve rifle 150 shown in Fig. 3 is as the follow-up valve rifle 200 and 250 elaborated with reference to Fig. 4 and Fig. 5
Ground is constituted as identically as possible with Fig. 1 and valve rifle 10 shown in Fig. 2.Identical component therefore in Fig. 3, Fig. 4 and Fig. 5 with figure
Identical reference numeral indicates and in order to avoid repeating in 1 and Fig. 2, about the elaboration before these component references.
Valve rifle 150 and Fig. 1 shown in Fig. 3 and 10 difference of valve rifle shown in Fig. 2 are, are being loosened instead of connecting link 74
Guide rail 152 is set on the end side 72 of bar 52, and replaces guide rail 94 can be free on the rear end of coupling bar 54 92
Rotationally it is supported with the connecting link 154 in connection 156 form of roller.
It is illustrated by imaginary circular arc 158 in the pivotal orientation of trip lever 52 valve rifle 150 shown in Fig. 3, the circular arc
Circle center is consistent with the supporting portion 64 of trip lever 52.The radius of imaginary circular arc 158 corresponds to and is drawing in connecting link 154
The spacing between contact site and supporting portion 64 in the first end section 160 of guideway 152.
In the resting position shown in fig. 3 of trip lever 52, connecting link 154 sticks on the of guide rail 152
There is small spacing in one end section 160 or away from end section 160.Other than first end section 160, guide rail
152 have intermediate section 162 and the second end section 164.In a manner of corresponding such as in valve rifle 10, the of guide rail 152
One end section 160 is also less tilted relative to the pivotal orientation of trip lever 52 compared to intermediate section 162 and second end
Portion's section 164 is less tilted compared to intermediate section 162 relative to trip lever 52.As long as connecting link 154 sticks on first
It in end section 160 or sticks in the second end section 164, then the pivoting angle change of trip lever 52 only causes coupling bar
54 small pivoting angle changes.However, if connecting link 154 sticks in intermediate section 162, the pivot of trip lever 52
Angulation change causes the significant pivoting angle of coupling bar 54 to change.
