Abstract
The invention provides a multi-ported valve disk. The multi-ported valve disk comprises a through public channel, and a plurality of branch channels are connected all around the public channel. The multi-ported valve disk is characterized in that two or more intersection points are formed between the plurality of branch channels and the public channel. According to the multi-ported valve disk provided by the invention, the distances between the branch channels and the public channel can be greatly reduced, and the space of the intersection points can be greatly reduced; furthermore, a plurality of intersection areas are formed by the plurality of intersection areas, but the sum of the volumes of the plurality of intersection areas is still far less than the volume of an only one intersection area of all branch channels; in addition, the intersection areas are small in volume and are capable of effectively isolating the plurality of branch channels, therefore the cross contamination can be greatly reduced.
Description
Technical field
The present invention relates to a kind of multiple-way valve dish.
Background technique
In detection field, the cross pollution degree of concatemer solenoid valve is the key factor affecting testing precision and the liquid-consumed amount of relevant circulation always.In order to reduce cross pollution to greatest extent, market there is disc type multiple-way valve and multipassage rotary valve.Disc type multiple-way valve be two three-way electromagnetic valves of traditional maturation are accessed several branched bottom converge on public passage a bit, failure rate is low, easy to maintenance, lower to fluid requirements.But the local width of branched bottom and angle each other, determining all passages still has at distance public passage and has just started interlaced during a segment length, defines the confluence that a volume is larger.Any one liquid all will pass through this confluence and mix with liquid wherein before entering public passage, therefore the size of confluence directly has influence on cross pollution degree, so the branched bottom of disc type multiple-way valve is no more than eight, moreover because confluence volume is large, cannot accomplish to be full of with air the effect that confluence reaches the multiple passage in interval.The public passage cavity of multipassage rotary valve is connected by rotating the branched bottom different from branched bottom cavity, branched bottom can be spaced, cross pollution is little, a lot of branched bottom can be connected, but it is comparatively strict to fluid requirements, any impurity all likely enters between public passage cavity and branched bottom cavity, causes the leakage of whole many admittances rotary valve.Rate of fault is high, inconvenient maintenance, high to fluid requirements.Therefore both had disc type multiple-way valve failure rate is low in the urgent need to one, easy to maintenance, the feature low to fluid requirements, has again little, the accessible a lot of branched bottom of multipassage rotary valve cross pollution and can by solenoid valve spaced apart from each other for branched bottom.
Summary of the invention
In order to overcome the problems referred to above, the invention provides failure rate is low, easy to maintenance, low to fluid requirements, cross pollution is little, multiple branched bottom can be connected and can with air effectively by isolated for multiple branched bottom multiple-way valve dish.
Technological scheme of the present invention is to provide a kind of multiple-way valve dish, and it comprises a public passage run through, and is connected with multiple branched bottom around described public passage.It is characterized in that: tell multiple branched bottom the center line of center line and described public passage have two or more joints.
Preferably, described branched bottom is in same plane part adjacent angle equal distribution.
Preferably, the other end of described branched bottom is connected with valve pocket.
Preferably, described valve pocket with enter liquid passage and be connected.
Preferably, liquid passage is entered described in and described multiple-way valve panel surface intersection is provided with into liquid passage retaining thread.
Preferably, described public passage and described multiple-way valve panel surface intersection are provided with public passage retaining thread.
Preferably, tell the part that branched bottom has a same center line joint and be positioned at the same plane vertical with described public passage.
Multiple-way valve dish of the present invention is assigned to by multiple branched bottom on two or more close joints uniformly, the angle increase at double each other of branched bottom on each joint, greatly reducing the distance between branched bottom and public passage, also reduce the space of confluence greatly.Although multiple joint defines multiple confluence, multiple confluences volume sum is still far smaller than the volume that whole branched bottom only has a confluence.Moreover confluence volume is little, with air effectively by spaced apart for multiple branched bottom, cross pollution can be greatly reduced.

Embodiment
Below preferred forms of the present invention is described in further detail.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, preferred embodiment takes following technological scheme: comprise valve disc 10, public passage 1, branched bottom 2, valve pocket 3, enter liquid passage 4, public passage retaining thread 11, enter liquid passage retaining thread 41.Public passage 1 runs through whole valve disc 10, and is being provided with public passage retaining thread 11 with the surperficial intersection of valve disc 10.Public passage 1 and 8 branched bottoms 4 have 2 close joints, and each joint has 4 branched bottoms 2, and angle is 90 degree each other.Branched bottom 2 the other end is connected with valve pocket 3, valve pocket 3 with enter liquid passage 4 and be connected.Enter liquid passage 4 the other end connect valve disc 10 surface and be provided with into liquid passage retaining thread 41 in intersection.Best mode for carrying out the invention is that 8 branched bottoms 2 are assigned to 2 joints uniformly, instead of the layout that traditional 8 branched bottoms 2 only have a joint.When multiple-way valve dish adopts 8 traditional branched bottoms 2 to be intersected at 1, as shown in Figure 5, branched bottom 2 diameter is R, and confluence area is 0.5*R*1.2R*8=4.8R2, and branched bottom 2 is 0.7R with the spacing of public passage 1; When multiple-way valve dish adopt of the present invention 8 branched bottoms 4 are intersected at 2 time, as shown in Figure 6, branched bottom 2 diameter is R, and confluence area is R2, and 2 confluence areas are 2R2, and branched bottom 2 and public passage 1 distance are 0.Adopt multiple-way valve dish of the present invention, total for branched bottom confluence cross-section area has been dropped to original 5/12, the spacing of branched bottom and public passage reduces to 0, both the size of confluence had been decreased, shorten again the distance between branched bottom and public passage, and can be effectively spaced apart by branched bottom with air, greatly reduce cross pollution.
