The working principle of fluid valve of the present invention is as shown in Figure 2:
First connecting port and second connecting port are distributed in fluid bleed outlet both sides symmetrically, width at the bottom opening of each hollow body of changeover valve core should be greater than first connecting port, one side margin to the distance between the fluid bleed outlet opposite side edge, promptly ought be arranged on the changeover valve core 1 of valve inner, 12 are positioned at the valve body leftward position, the bottom opening of each hollow body of changeover valve core just covers first connecting port and the fluid bleed outlet in valve body left side hermetically, make it to be interconnected, and second connecting port on valve body right side is exposed at changeover valve core 1,12 outside, be communicated with motive fluid inlet 5, and the first control signal mouth 7 of this valve body one side, 10 by changeover valve core 1, first connecting port of 12 these side bottoms and fluid bleed outlet 6,9 communicate carries out fluid and releases and realize the output of fluid control " 0 ", simultaneously, the motive fluid of the motive fluid inlet 5 that is provided with of valve body is by changeover valve core 1, the second control signal mouth 8 of second connecting port of 12 bottom opposite sides and valve body opposite side, the input that 11 communicate carries out fluid realizes the output of " 1 " of fluid control.
When changeover valve core 1,12 by leftward position to the right during the switch motion of position, thrust axis 4 slides from left to right, it is a kind of or combination that electronic, pneumatic, hydraulic pressure or machinery touch that thrust axis 4 suffered Driving forces can adopt.When the step that is provided with when thrust axis 4 contacts with the left side of touching slide block 3, thrust axis 4 drives and touches slide block 3 slip from left to right together, touch slide block 3 from left to right sliding zone move hollow body 1 to spool, 12 by leftward position position switching to the right, at this moment, the first control signal mouth 7 in valve body left side, the input of carrying out fluid that communicates of the 10 motive fluid inlets 5 that are provided with valve body respectively realizes the output of " 1 " of fluid control, simultaneously, the second control signal mouth 8 on valve body right side, 11 respectively with fluid bleed outlet 6,9 communicate carries out fluid and releases and realize the output of fluid control " 0 ", so finish simply or more complicated intelligent control, realize the functional purpose of different application occasion by the design control of " 0 " and " 1 ".
As shown in Figure 3: in the occasion of automatic reciprocating commutation control, step by setting thrust axis 4 with touch sliding distance length between the slide block 3 and set and control whole reciprocating stroke and cancelled the trigger mechanism that is similar to position limit switch, sliding distance length between the step of described thrust axis 4 and the shake-up slide block 3 is not less than the maximum diameter of first connecting port or second connecting port, spring casing coupling 2,13 when the changeover valve core switch motion, drive moving plate 15 by touching slide block 3,19 pairs of telescopic pipes 14, the spring of establishing in 17 16,18 compressed energy-storages drive moving plate 15 when touching slide block 3,19 springs 16 when crossing the valve body central point, 18 compression can discharge and promote touch slide block 3 and finish commutation and put in place.In the occasion of non-automatic reciprocating reversing control, purely as the control of valve convection cell break-make, the step of thrust axis 4 and the sliding distance length of touching between the slide block 3 need not, and spring casing coupling 2,13 can not wanted fully.
Described in the present invention working fluid can be liquid or gas.As shown in Figure 1: adopt in this embodiment be thrust axis 4 drive be arranged on valve inner shake-up slide block 3 directly to two changeover valve cores 1,12 control that commutates, realize the simple and reliable control of fluid that commutates.In the present embodiment, the cross section of this valve body is a quadrilateral, and two opposite flanks of valve body are provided with the fluid bleed outlet, and two opposite flanks are provided with the spring casing coupling in addition, if the expansion control flow rate, this invention technical characteristics also can adopt the situation of the work of more changeover valve core.Promptly the cross section of this valve body can be n limit shape, wherein n is not less than 4 even number, fluid bleed outlet and spring casing coupling are set on each side of this valve body successively at interval, be that each side sets gradually fluid bleed outlet, spring casing coupling ... fluid bleed outlet, spring casing coupling, if employing odd structure, thereby the asymmetric layout of spring casing coupling will cause and touch the uneven shake-up slide block generation additional wear that makes of slide block active force so, influences the global reliability and the operating life thereof of valve.Owing to adopted said structure, in the occasion of reciprocating reversing control directly to the control that commutates of commutation spool, realization is to the simple and reliable control of commutation fluid, double spool or more spools are arranged at same valve body in order to have increased the effectively simple and reliable employing of control fluid flow simultaneously, not only solve the prior art problem, overcome the big flow of convection cell better, the control of the high pressure resistant and super high pressure fluid of super-flow, changeover valve core has the self-compensating sealing simultaneously, adopting the control of this fluid to have the convection cell cleaning requires low and has technical characteristicss such as explosion-proof, make the practical application and the extension of this technological scheme expand, can be applicable to existing use equipment and treat that research and development technology breaks through the equipment of project etc., as be applicable to a practicable reciprocal hydraulic air compressor, large-scale LPG compressor, or can be applicable to and be similar to a kind of pneumatic hammer, reciprocating pump, diaphragm pump, Airless spraying, a kind of high pressure, the super high pressure hydraulic pump is similar to equipment such as a kind of water cutter, and it is simple in structure to achieve identical functions, reliably, low-cost long service life, applied widely.
