Abstract
The invention provides a kind of ten direction changeover valve; the switching valve includes valve rod; together with valve rod is poured with flap; in order to preferably drive the rotation of flap, valve rod is connected with motor or other manner drives 12 passages on the left rotation and right rotation of valve, valve disc; wherein 2 holes are protection gas; another 10 holes form 5 groups under the particular design of flap and communicated two-by-two, and left rotation and right rotation certain angle formation left and right switching, reaches transition effect under the drive of motor or other manner.Under the elastic force of butterfly spring, valve disc and flap tight seal make valve reach good sealing effectiveness.Protect conduit not disturbed by extraneous other gases by pure inert gas well in the effect lower valve core segment of three sealing rings, solve analyze into, sample, gas circuit by external interference it is difficult the problem of.
Description
Technical field
The present invention is the core component of a variety of analytical instrument instrument such as gas chromatograph, mainly many with gas, liquid etc.
Plant the production, scientific research, the utilization of teaching of analysis industry.
Technical background
Current many analysis industries use four-way, six logical, the eight logical modes being combined in production, research and development major part,
Even using the method for hand injection.This total method, inefficiency, difficult design, valve pipeline pressurize hardly possible, external interference factor
Analytical conclusions error greatly ... is big;If any harm gas experiment or analysis, not only to party cause don't fail to injury, while all
Surrounding environment brings pollution, and negative consequence is brought to society and enterprise.
This ten direction changeover valve is to solve problem above under the unique design of flap.This valve body is in flap and the gas of valve disc
Hole is communicated two-by-two, can be achieved multi-pipeline simultaneously switch, analyze, enter sampling, when valve under the driving of external force left rotation and right rotation, make to lead to
Mutually switching is communicated stomata two-by-two between two adjacent holes of left and right.Valve element position is all the time by one pure inert gas institute
Protection, so internal gas will not be influenceed because of the infiltration of material because of external environment or gas, can be in closed environment bar
Enter sampling under part, it is ensured that accuracy, the security reliability of analysis.
This valve cleverly designs internal valve pool and blow vent is appropriately docked, and realizes that gas is real during inflow and outflow
Existing pipeline minimal dead volumes are quickly taken away.
The content of the invention
Technical principle
This ten direction changeover valve is allowed to valve seal, principle as shown in figure 1, to have produced pretightning force between flap 17 and valve disc 18
As follows, rotating end cap 21 is allowed to decline while extruding valve disc 18, valve disc is by the spacing rear of alignment pin 23 to fixation, Bu Huisui
Rotation, pour integral between flap 17 and valve rod 16, the lower section of valve rod 16 is provided with butterfly spring 14, in the effect of elastic force
It is lower flap 17 up push away between valve disc 18 produce pretightning force be allowed to valve seal.
Valve disc has 1-10 passage to form 5 groups of passages communicated two-by-two under the special construction of circular flap 17.When
As shown in Fig. 2 hole 1 and hole 2 are identical two-by-two when valve runs to position 1, similarly hole 3 and hole 4, hole 5 and hole 6, hole 7 and hole 8, hole
9 and hole 10, when valve runs to position 2 as shown in figure 3, hole 1 and hole 10 are identical two-by-two, similarly hole 2 and hole 3, hole 4 and hole 5,
Hole 6 and hole 7, hole 8 and hole 9.
Motor 11 and valve rod 16 use axis hole connected mode to reduce mutual motion between the two, in motor or other portions
Drive flap 17 to rotate under the driving of part, valve motion is allowed to, while under the position-limiting action of spacer pin 22, flap 17 can only revolve
Turn the fixed number of degrees, to ensure that 10 passages on valve disc are identical two-by-two.In order to reduce the load of motor while valve motion,
Plain thrust bearing 13 is installed in the bottom of butterfly spring 14, reduces the frictional force between butterfly spring 14 and valve body 12, from
And reduce the load of motor.
Because of the influence of environment or ambient atmos, there is certain infiltration between material and material, can so cause by
Gas or carrier gas are surveyed, is influenceed because permeating by external environment, thus the accuracy of impact analysis result.So in valve element
Position includes（Valve disc 18, flap 17, valve rod 16）Interstitial site, can by one pure inert gas to filling, protect it is whole
Individual valve element position is not influenceed by external environment, it is ensured that precision of analysis.Inert gas entrance 24 flows by valve disc 18
Gap between valve disc and valve rod 16, is flowed between valve seat 12, end cap 21, valve disc 18, valve rod 16, flap 17 by valve rod
Gap, is finally flowed out by inert gas outlet 25, at the same 19. sealing gaskets 1,20. sealing gaskets 2,15.O type sealing rings sealing
Under effect, the gap location of valve hole part is surrounded by pure inert gas shielding all the time, it is ensured that precision of analysis.
