Positioned at center flow channels medium position, any one end will not be shifted to by B mouth or the closing of C mouth, now for One In and Two Out, if B mouth and C
At mouthful, fluid medium pressure is unequal, then valve element can be shifted to the less one end of pressure under differential pressure action and seal B mouth or C mouth
Close, now for one-in-and-one-out, valve element with the pressure reduction of fluid media (medium) as driving source, by the pressure reduction of fluid media (medium) at B mouth and C mouth from
Dynamic distribution exit passageway.Contrary, when B mouth and C mouth as entrance, A mouth as outlet when, if fluid media (medium) at B mouth and C mouth
Pressure is equal, then valve element will be located at center flow channels medium position, will not shift to any one end and close B mouth or C mouth, now
For Two In and One Out, if fluid medium pressure is unequal at B mouth and C mouth, then valve element can shift to pressure relatively under differential pressure action
Little one end simultaneously by B mouth or the closing of C mouth, now for one-in-and-one-out, valve element with the pressure reduction of fluid media (medium) as driving source, by B mouth
Automatically distribute intake channel with the pressure reduction of fluid media (medium) at C mouth；The utility model structure is simple, low cost of manufacture, using fluid
The pressure reduction of medium is driving source, it is possible to achieve the automatic distribution of port.

Specific embodiment
With reference to the accompanying drawings and examples the utility model is further described.
As shown in figure 3, a kind of reciprocating triple valve of pressure differential, including valve body 4, in valve body 4, it is provided with line flowing channel 6,
The two ends of line flowing channel 6 and middle part are connected with three joints 1 respectively, and joint 1 is located on valve body 4（Joint 1 is adopted with valve body 4
One of connected modes such as threaded, flange connects, welding or Several combinations, can also be arranged between joint 1 and valve body 4
Seal 2）, in line flowing channel 6, it is provided with valve element 3（Valve element 3 is metal or the nonmetallic materials with corrosion-resisting function）, valve element 3
There is gap and line flowing channel 6 inwall between, valve element 3 is in fluid media (medium)（Fluid media (medium) is liquid or gas）In the presence of can be by
The sealing surface compact closing of 6 liang of end connectors 1 of line flowing channel, valve element 3 can not deviate from from line flowing channel 6 center contact 1, can not be by
Line flowing channel 6 center contact 1 is closed（Line flowing channel 6 center contact 1 be can ensure that with intersection's opening shape of line flowing channel 6
3 points contact or linear contact lay with valve element, i.e. both served the effect limiting abjection, and fluid media (medium) will not be hindered to flow out again）.
The port of name 6 liang of end connectors 1 of line flowing channel is respectively B mouth and the port of C mouth, line flowing channel 6 center contact 1 is
A mouth, when A mouth as entrance, B mouth and C mouth as outlet when, if fluid medium pressure is equal at B mouth and C mouth, then valve element 3
Center flow channels 6 medium position will be located at, any one end will not be shifted to by B mouth or the closing of C mouth, now for One In and Two Out, if B
Mouthful and C mouth at fluid medium pressure unequal, then valve element 3 can shift to the less one end of pressure and by B mouth under differential pressure action
Or C mouth closing, now for one-in-and-one-out, valve element 3 with the pressure reduction of fluid media (medium) as driving source, by fluid media (medium) at B mouth and C mouth
Pressure reduction automatically distribute exit passageway.Contrary, when B mouth and C mouth as entrance, A mouth as outlet when, if at B mouth and C mouth
Fluid medium pressure is equal, then valve element 3 will be located at center flow channels 6 medium position, will not shift to any one end by B mouth or C
Mouth closing, now for Two In and One Out, if fluid medium pressure is unequal at B mouth and C mouth, then valve element 3 can be in differential pressure action
Under shift to the less one end of pressure and by B mouth or C mouth closing, now for one-in-and-one-out, valve element 3 with the pressure reduction of fluid media (medium) for drive
Dynamic source, distributes intake channel automatically by the pressure reduction of fluid media (medium) at B mouth and C mouth；The utility model structure is simple, manufacturing cost
Low, the pressure reduction using fluid media (medium) is driving source, it is possible to achieve the automatic distribution of port.
As shown in figure 4, in the present embodiment, the joint 1 at line flowing channel 6 two ends each connects a main line, every master
One bye-pass is designed with pipeline, each bye-pass is designed with a valve 5（Valve 5 can be hand-operated valve, magnetic valve or
Motor-driven valve）.Bye-pass and valve 5 are set up on main line, the effect of pressure release during Open valve 5, can be played, you can adjustment B mouth
With the pressure reduction of fluid media (medium) at C mouth, when B mouth or C mouth are closed by valve element 3, B mouth larger for pressure or C mouth pressure release can be made
B mouth and C mouth pressure is equal so that valve element 3 returns in the middle part of line flowing channel 6, recovers One In and Two Out or Two In and One Out state.When by B
When mouth and C mouth are all opened, B mouth or C mouth pressure release can be made B mouth and C mouth produce pressure reduction, valve element 3 can be shifted under differential pressure action
B mouth or C mouth are simultaneously closed by the less one end of pressure, and now for one-in-and-one-out, the valve 5 set up can actively play pattern switching
Effect（Because bye-pass and valve 5 act primarily as the effect of pressure release, so its bore and negotiability are all less）.
As shown in Figure 3 and Figure 4, in the present embodiment, valve element 3 is spheroid, and the sealing surface of 6 liang of end connectors 1 of line flowing channel is
The conical surface.As shown in figure 5, in another kind of embodiment, valve element 3 middle part is cylinder, two ends are cone, and cone is provided with close
Sealing groove, is provided with sealing ring, the sealing surface of 6 liang of end connectors 1 of line flowing channel is the conical surface in seal groove.
It should be appreciated that for those of ordinary skills, can be improved according to the above description or be converted,
And all these modifications and variations all should belong to the protection domain of the utility model claims.
