The three-way slave logical valve comprises two sets of valve covers and valve caps, follow-up mechanisms which are arranged in the two sets of valve covers and valve caps and are composed of a servo valve rod and a follow-up cone valve, and a servo follow-up system composed of the oil holes on the components of the valve body and the oil passages and oil reservoirs formed between the components. The utility model has the advantages of compact structure, good processing property, simple processing and convenient maintenance; the manufacturing cost can be reduced and the labor intensity of the operator can be relieved. The three-way slave logical valve has the advantages of fast and short time of the reverse movement and high sensitivity, and the three-way slave logical valve is suitable for the hydraulic control system with large flow quantity.
Description
The utility model relates to a kind of direction of the convection cell of liquid control system, threeway servo-actuated logical valve that flow is realized various control of being used for.
In the existing liquid control system, the normal control mode that adopts band small electrical magnet valve to make the Twoway valves of guide's control, its service behaviour is single.Arbitrarily control the necessary pilot valve control of adopting different performance for realizing making simultaneously the direction of fluid, flow.This has not only increased the technical difficulty of convection cell synchronization control, and makes complex structure, and is not compact.
The purpose of this utility model provide a kind of can be servo the threeway servo-actuated logical valve of servo-actuated control, its work commutation is short and fast, highly sensitive, safe and reliable switching time, good airproof performance, shock-resistant, steering force is little, and is easy to maintenance, and working medium is not had specific (special) requirements.
The purpose of this utility model is achieved in that this device is improved to make on the architecture basics of existing Twoway valves.It comprises two groups of valve pockets and the valve gap that is contained in the valve body, places the servo follower of valve pocket and valve gap, is made of servo valve rod and servo-actuated cone valve.Be processed with oilhole on servo valve rod and the servo-actuated cone valve, each inter-module forms in these oilholes and the valve body oil duct and oil pocket are formed servo followup system.This device is easy to realize that by servo valve rods of handled such as manually control, electronic control, hydraulic control, microcomputer control direction, the flow of convection cell are arbitrarily controlled simultaneously.
Because the utility model only by handling the action of servo valve rod, drives the servo-actuated cone valve, control the servo followup system of each oilhole, oil duct, oil pocket composition, thus compact structure, good manufacturability, commutation is short and fast actuation time, can improve working sensitivity.Because of steering force is little, easy to maintenance, so can alleviate labor intensity of operating personnel.This installs easy processing, has the advantage that versatility is good and standardization level is high, therefore, can reduce manufacture cost, is convenient to wide popularization and application.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the longitudinal sectional view of a kind of concrete structure of the utility model.
Fig. 2 is the working principle schematic representation that the utility model constitutes three-way diverter valve.
Fig. 3 is the working principle schematic representation that the utility model constitutes four-way change-over valve.
Describe concrete structure of the present utility model and working condition in detail according to Fig. 1～3.In the accompanying drawing sequence number 1., 7. servo valve rod, 2. valve gap, 3. spring, 4., 8. servo-actuated cone valve, 5. valve pocket, 6. valve body.The valve body of this device be equipped with respectively in two chambeies about 6. valve pocket 5. with valve gap 2., the servo valve rod that constitutes servo follower 1., 7. with the servo-actuated cone valve 4., 8. after the assembling, place respectively each valve pocket 5. with valve gap 2. in, and utilize 3. centering location of spring, by bolt 6. 2. valve gap reinforced with valve body.For preventing oil liquid leakage, valve gap 2., the position that 5. 6. joins with valve body of valve pocket, utilize seal ring to seal respectively.6. valve body has the interface P that communicates with the fluid power source, the interface A that communicates with working oil chamber, the interface T that communicates with oil sump tank.Servo valve rod is processed with the oilhole 15,17,19 of connection on 1., the servo-actuated cone valve is processed with the oilhole 1,3 and 11,13 of connection on 4., servo valve rod is processed with the oilhole 16,18 of connection on 7., and the servo-actuated cone valve is processed with the oilhole 2,4 and 12,14 and 20,22 of connection on 8..The oilhole 23 that 2. these oilholes and valve body oil duct that each inter-module forms in two chambeies about 6. and oil pocket 5,7,9,21,27,29,31,6,8,10,24,26,28,30 and valve gap are gone up, the oilhole 25 that 6. valve body is gone up etc. are formed servo followup system jointly.
When the fluid power source communicated (shown in Figure 1) with interface P, high-voltage oil liquid entered 9 by 1,3,5,7 in the servo followup system, and be not communicated with 15 this moment 11,13, and oil pocket 9 just forms hyperbaric chamber.During because of the design setting value, servo-actuated cone valve upper section sum is greater than its lower section sum, so the hydraulic coupling in the chamber, servo-actuated cone valve upper end is added the elastic force that 3. spring applies, thereby made the servo-actuated cone valve 4. close tight P mouth and A mouth greater than the hydraulic coupling in its chamber, lower end.If the A mouth has high-voltage oil liquid to enter 10 by 29,31,30,2,4,8,6,4. the same with the servo-actuated cone valve, also make the servo-actuated cone valve 8. close two mouthfuls of tight A, T.Therefore, the operating mode of this device is in P, A, three mouthfuls of equal closed conditions of T.When handling servo valve rod and 1. move up certain position, 5,7 and 9 cut off, and 11,13 are communicated with 15 simultaneously, and P mouth high-voltage oil liquid can't enter 9, and chamber 9 interior high-voltage oil liquids begin by 17,19,21,23, the 25 liquid inflow T mouths of draining the oil.Press the chamber so 9 become nothing, the servo-actuated cone valve is the no hydraulic coupling in upper end 4., has only very little spring force effect, the hydraulic coupling of the high-voltage oil liquid of its lower end P mouth just promotes the servo-actuated cone valve and 4. is moved upward to the displacement amount that 1. moves up with servo valve rod, make 11,13 and 15 to cut off, 5,7 are communicated with once more with 9, stop to move up up to the servo-actuated cone valve, end when being stabilized in certain position, make P mouth, A mouth have certain high-voltage oil liquid to pass through.By same operating method, upper and lower shift servo valve rod 1., 7., can make the servo-actuated cone valve 4., 8. follow servo valve rod 1., 7. corresponding upper and lower moving, with the direction that reaches random control fluid, the purpose of flow.Structure of the present utility model can be according to the requirement of applying working condition, with about two chambeies be arranged vertically.
The utility model is best suited for hydraulicdriven plunger cylinder control system, also being applicable to hydraulic pressure---pneumatic miscella cylinder system is hydraulic pressure---air cushion forging hammer, pile driver etc. have the equipment of specific (special) requirements that a kind of desirable high-volume hydraulic control element is provided. This device can also design the 3-position 4-way slave logical valve that obtains as shown in Figure 3 by improving, and also can enlarge the scope of application, is applicable to the piston oil-cylinder control system.
