Bar；Be additionally provided with an anti-blocking piece in inking chamber body, the anti-blocking piece be located at opening of the delivery port in inking chamber and with sealing
Circle is in contact.
Or the inking chamber in valve body is three, delivery port and water inlet in valve body surface are three；Each
Inking chamber connects with a water inlet and delivery port respectively；A movable ball and a sealing are equipped with each inking chamber
Circle；The one of side outer wall of valve body is provided with a longitudinally connected raised line, and another side outer wall, which is provided with one, can accommodate connection
The longitudinally connected cell body of raised line；Three anti-blocking pieces are additionally provided with inking chamber body, opening of each delivery port in inking chamber is equal
Provided with an anti-blocking piece.
The delivery port and water inlet are cylindrical, and the axial hole in delivery port and water inlet connects with inking chamber.
Advantageous effects：When ink enters the inlet end on valve body, the upper/lower terminal of ball can form pressure difference,
When pressure difference reaches to a certain degree, the pressure of ink overcomes the gravity of ball, and ball moves up, and ink will be from the week of ball
Enclose and flow through, flowed out eventually through the axial hole in delivery port, and ball is then blocked by the anti-blocking piece of inking chamber；When ink reverse flow
When dynamic, ball is relied under the gravity of itself and the ink collective effect entered from the axial hole of delivery port, forces ball with being located at
Untill the circular seal ring of opening of the water inlet in inking chamber is in close contact, so as to reach the effect of sealing；In single ink
Longitudinally connected raised line is set on the valve body-side outer wall of water cavity, and sets up longitudinal direction separately on two side outer walls of valve body of three inking chambers and connects
Raised line and longitudinally connected cell body are connect, then is easy to combine the valve body of single inking chamber with the valve body of three inking chambers, while also just
Combined in the valve body of three two or more inking chambers, realize a variety of collocation modes, so as to which the scope of application is wider；Compared with
Technology is compared, and the utility model, which has, decays that small, response is fast, prevents ink backflow, applied widely and sealing to ink pressure
The advantages of effect is good.
Brief description of the drawings
Fig. 1 is the schematic perspective view of first embodiment of the present utility model；
Fig. 2 is the schematic cross-section of first embodiment of the present utility model；
Fig. 3 is the schematic perspective view of second embodiment of the present utility model；
Fig. 4 is the schematic cross-section of second embodiment of the present utility model.
Embodiment
In order that those skilled in the art more fully understand this New Scheme, below in conjunction with the accompanying drawings with embodiment to this
Utility model is described in further detail.
Embodiment one
As shown in Figure 1-2, the anti-return check valve for continuous ink feeding includes valve body 1, and valve body is interior at least provided with an ink
Water cavity 101, at least provided with a delivery port 102 and a water inlet 103, the delivery port 102 and water inlet in valve body surface
103 connect with inking chamber 101；A movable ball 2 and a sealing ring 3 are provided with inking chamber；The sealing ring 3 be located at into
Opening of the mouth of a river 103 in inking chamber.
During original state, because the effect of gravity, the ball 2 is located at opening of the water inlet 103 in inking chamber simultaneously
It is in contact with sealing ring 3.
In the present embodiment, the inking chamber 101 in valve body is three, delivery port 102 and water inlet in valve body surface
103 be three；Each inking chamber connects with a water inlet and delivery port respectively；An activity is equipped with each inking chamber
Ball 2 and a sealing ring 3；The one of side outer wall of valve body 1 is provided with a longitudinally connected raised line 104, outside another side
Wall is provided with a longitudinally connected cell body 105 that can accommodate connection raised line；Three anti-blocking pieces 4 are additionally provided with inking chamber body, each
Opening of the delivery port 102 in inking chamber is equipped with an anti-blocking piece 4.
Embodiment two
As shown in Figure 3-4, an inking chamber 101 is provided with valve body 1, what valve body surface connected provided with one with inking chamber
Delivery port 102 and water inlet 103；A movable ball 2 and a sealing ring 3 are provided with inking chamber；Set on valve body-side outer wall
There is a longitudinally connected raised line 104；An anti-blocking piece 4 is additionally provided with inking chamber body, the anti-blocking piece is located at delivery port 102 in ink
Opening in water cavity.
The light weight of ball 2, response are fast.
The delivery port 102 and water inlet 103 are cylindrical, axial hole 102a in delivery port and water inlet and
103a connects with inking chamber.
Longitudinally connected raised line 104 is set on the valve body-side outer wall of single inking chamber, and in the valve body two of three inking chambers
Set up longitudinally connected raised line 104 and longitudinally connected cell body 105 on individual side outer wall separately, be then easy to the valve body of single inking chamber and three
The valve body combination of inking chamber, while the valve body combination of three two or more inking chambers is also allowed for, a variety of collocation modes are realized,
For example the valve body of single inking chamber, the valve body of single inking chamber combine with the valve body of three inking chambers, two or more three
Valve body combination of inking chamber etc.；So as to which the scope of application is wider.
When ink enters the inlet end on valve body 1, the upper/lower terminal of ball 2 can form pressure difference, when pressure difference reaches one
When determining degree (pressure difference for normally only needing very little), the pressure of ink overcomes the gravity of ball 2, and ball 2 moves up, and ink will
Flow through around ball 2, flowed out eventually through the axial hole 102a in delivery port, and ball 2 is then by the anti-blocking piece 4 of inking chamber
Block；When ink reverse flow, ball 2 relies on the gravity of itself and the ink entered from the axial hole 102a of delivery port common
Under effect, untill forcing the close contact of circular seal ring 3 of the ball 2 with being located at opening of the water inlet in inking chamber, so as to
Reach the effect of sealing, compared with the existing technology, small, response is fast, prevents ink with decaying to ink pressure for the utility model
The advantages of backflow and good sealing effect.
Although depict the utility model by embodiment to create, it will be appreciated by the skilled addressee that the utility model
There are many deformations and change without departing from spirit of the present utility model, it is desirable to which appended claim includes these deformations and change
Without departing from spirit of the present utility model.
