Description

  • The invention relates to an actuating valve according to the preamble of patent claim 1.
  • From such an actuation valve is required that after release of the respective actuated switching valve of the pneumatic cylinder or the piston is pressurized on both sides so that upon release of the previously actuated valve no further venting or depressurization of both pressure chambers takes place, but a self-holding of the pneumatic cylinder is effected ie, a two-sided effective pneumatic cylinder is to be moved by means of preferably manually operated switching valves in its respective end positions and can be stopped immediately in its feed movement in the absence of the operation.
  • At one in the FR-A-2 660 726 described valve according to the preamble of claim 1 are used as the pneumatic cylinder immediately upstream multi-way valves as 2/2-way valves, so that an additional compressed air channel is needed to control these multi-way valves so that upon actuation of one of the two switching valves each having a pressure chamber Compressed air is applied and the other pressure chamber is relieved.
  • The US-A-3,164,959 describes a system with an actuating valve for a hydraulic cylinder having two separate from each other by a piston attached to a piston rod pressure chambers. The designed as a 5/2-way valve valve is connected via a conduit and valve system an alternately acting in two directions pump for hydraulic fluid upstream; This pump is connected to a reservoir for hydraulic fluids by means of two lines equipped with check valves. When the pump is effective in one direction, hydraulic fluid is supplied to one pressure chamber of the hydraulic cylinder while the hydraulic fluid from the other pressure chamber flows back into the reservoir.
  • In a hydraulic feed pump, the pressure medium is always conveyed only in one direction, so that the hydraulic pump upstream lines are relieved of pressure, while in a pneumatic system, the compressed air used in this context, unless appropriate shut-off valves are present, can distribute over the entire line system , The known hydraulic system can thus not be used as a pneumatic system without fundamental modifications being carried out, so that practically only secondary features of the pneumatic system can be found again from the original design of the hydraulic system.
  • The invention is based on the object, a relation to that in the FR-A-2 660 726 to provide improved actuation valve.
  • To achieve this object, an actuating valve according to claim 1 is proposed according to the invention, the advantages of which will become apparent from the following description of the figures.
  • A preferred structural embodiment of an actuating valve, with which the problem underlying the invention can be achieved, is described in claim 3.
  • According to another invention, it is proposed to dispense with a total of all valve units on slide valves and instead of so-called. Seat valves to use, as expressed in the claims 2 and 4 expressed. An actuation valve according to claims 3 to 10 is characterized in particular by its compact and thus the operation facilitating construction.
  • For the sake of simplicity, in the claims 4 to 10 with respect to the reference only partially refer to the one, for example in Figure 3 right illustrated valve system, since the structure of in FIG. 3 The valve system shown on the left is identical to the valve system shown on the right.
  • The invention is described in more detail below with reference to the drawing:
    • FIG. 1a shows a schematic diagram of the actuating valve in the rest position;
    • FIG. 1b shows the circuit diagram in one of the two operating positions;
    • FIG. 2 shows a side view of the connected to a two-sided pneumatic cylinder actuating valve;
    • FIG. 3 shows a sectional view of the actuating valve;
    • FIG. 4 shows a sectional view according to the arrows IV-IV in FIG. 3 ;
    • FIG. 5 shows in an enlarged view one of the two valve units of the actuating valve according to the invention.
    • FIG. 6a shows an enlarged view of a portion of the valve housing in section;
    • FIG. 6b shows two of the valve body outside the valve body.
  • FIG. 1a shows the actuating valve 23 in the rest position; FIG. 1b shows an operating position in which the piston rod is moved 8.1 in the direction of arrow f1 in the cylinder 8.
  • According to FIG. 1a are connected to a compressed air source P by means of connecting lines L2, R2, two switching valves in the form of, for example, manually operable 3/2-way valves L1, R1. To the switching valves L1, R1 close line branches L3, R3, the check valves L4, R4 contain and lead to two 3/2-way valves L5, R5, which are connected via lines L6, R6 to the pressure chambers 8.3, 8.4 of the pneumatic cylinder 8 can be connected. Of the line branch L3 branches off between the switching valve L1 and the check valve L4, a control line L7, which leads to the 3/2-way valve R5, upon application of this control line L7 with compressed air, the 3/2-way valve R5 against the force of the spring R8 to adjust to the venting position. The same purpose is used to adjust the 3/2-way valve L5 against the force of the return spring L8, the control line R7. The switching valves L1, R1 and the check valves L4, R4 and the valves L5, R5 are preferably poppet valves, which have valve bodies equipped with sealing rings, which are displaceable against spring force in valve chambers having corresponding valve seats for the sealing rings.
  • Upon actuation of the switching valve L1 by means of the actuating element or button L9 in the direction of arrow f2, the connection between the line L2 and the line branch L3 is established, whereby the check valve L4 is opened and compressed air flows through the line L6 in the pressure chamber 8.3. At the same time the 3/2-way valve R5 is adjusted in the direction of arrow f3 in the vent position via the branching of the branch L3 control line L7, in which the pressure chamber 8.4 is vented via line R6 and an exhaust throttle R10.
  • When the button L9 is released, the switching valve L1 is returned by the return spring L11 to the in FIG. 1a shown resting and venting position, whereby the control line L7 vented and thus the 3/2-way valve R5 is returned under the influence of the return spring R8 back to its original position.
  • The actuation valve according to the invention thus combines schematically considered four separate 3/2-way valves and two check valves, which are preferably designed as seat valves and linked together such that at z. B. manual operation of one of the two switching valves L1, R1 compressed air flows into one of the two pressure chambers of the pneumatic cylinder, while the other pressure chamber is vented defined via an exhaust throttle, so that upon release of the previously actuated switching valve of the pneumatic cylinder is acted upon on both sides with compressed air and thus a latching of the pneumatic cylinder or its piston is achieved.
  • By operating the switching valve R1 by means of the button L9, the pressure chamber 8.4 is supplied with compressed air, while the pressure chamber is 8.3 vented via the the 3/2-way valve L5 associated throttle L10.
  • That in the Figures 3 . 4 . 5 . 6a and 6b illustrated in a preferred constructive embodiment actuating valve 23 is characterized in that the basis of the FIGS. 1a and 1b described valve or control elements are accommodated in a compact valve block to save space.
  • This valve block is made according to FIG. 3 from a lower part 25 and an upper part 26. A guided through the upper part 26 and connectable to a compressed air source P channel 27 opens into a distribution chamber 28. In the lower part 25, two valve bodies 31, 31 'are stored or guided, which by means of button L9, R9 against the force of return springs 33, 33 'in the distribution chamber 28 can be inserted.
  • The valve body 31 is mounted by means of a valve stem 31.1 to form an annular gap in a bore 25.1 of the valve block lower part 25 such that the located above the valve stem 31.1 portion of the bore 25.1 is open to the environment, as in FIG. 3 for the button L9, see guide shaft 31.1 'and bore 25.1'.
  • To the bore 25.1 is followed by a bore portion 25.4 and a valve chamber 25.2, in which upon actuation of the button R9 a bilaterally supported sealing ring 31.2 of the valve body 31 is sealingly guided. The diameter of the bore portion 25.4 is greater than the diameter of the valve chamber 25.2 such that the sealing ring is housed in nichtbetätigtem switching valve in the bore portion 25.4 that laterally on this sealing ring 31.2 past a connection between the channel 35 and the environment is made. The valve chamber 25.2 opens into the distribution chamber 28 to form a valve seat 25.3. A channel 35 adjoins the valve chamber 25.2 laterally above the sealing ring 31.2.
  • A sealing ring 31.4 of the valve body 31 is pressed in the rest position by the spring 33 against the valve seat 25.3, as in FIG. 3 for the valve body 31 'is shown.
  • To the channel 35 closes according to the FIGS. 4 and 6a a stepped bore, which receives a double-valve unit consisting of a first, lower valve body 36 and a second upper valve body 38. This stepped bore has a guide section 39 adjoining the channel 35, to which a valve chamber 41 adjoins to form a valve seat 40. Connected to this valve chamber 41 via a further valve seat 42 is a valve chamber 43, to which a valve seat 44 is connected via a valve chamber 45 into which a venting channel 46 opens laterally.
  • The valve body 36 has a guided in the guide bore 39 valve stem 36.1, which has distributed over its circumference a plurality of axial slots 36.2. At the top of the valve stem 36.1 is a sealing ring 36.3, in the rest position is pressed by the supported between the lower and upper valve bodies 36, 38 return spring 36.4 against the valve seat 40.
  • The valve body 38 has a guided in the valve chamber 41 valve stem 38.1, which is designed substantially as a hollow cylinder with lateral wall openings 38.2 and with its interior with the valve chamber 41 may be in communication. This valve body 38 carries a first, lower sealing ring 38.3 for cooperation with the valve seat 42 and a second, upper sealing ring 38.4 for cooperation with the valve seat 44. The valve body 38 is further provided with a sealingly guided in the valve chamber 45 piston 38.5.
  • The actuating valve contains, in addition to the valve unit described in connection with the valve bodies 31, 36 and 38, a second symmetrically constructed valve unit whose individual parts in FIG. 3 are shown on the left and the same reference numerals as in FIG. 3 Carrying valve unit shown on the right, wherein for these valve units shown on the left is added to the reference numerals a superscript index line.
  • The two valve units are according to the control lines L7, R7 of FIGS. 1a and 1b by linked to the channels 35, 35 'subsequent control channels 47 and 47' with each other. So according to the Figures 3 and 4 the branching off from the channel 35 control channel 47 a transversely through the valve block upper part 26 extending connecting channel 47.1, which opens with its mouth 47.2 above the valve body 38 'in the valve chamber 45'.
  • By pressing the button R9 the in FIG. 3 right illustrated valve unit operated. Characterized the sealing ring 31.4 of the valve body 31 is lifted from the distribution chamber 28 facing the valve seat 25.3, so that compressed air flows into the channel 35 and the guide bore 39. Thereby, the lower valve body 36 is displaced against the force of the return spring 36.4 upwards, and the sealing ring 36.3 is lifted from the valve seat 40, so that compressed air through the radial slots 36.2 in the valve chamber 41 and thus Also flows through the wall openings 38.2 of the valve stem 38.1 in the valve chamber 43. This valve chamber 43 is connected via a lateral opening 43.1 with a connection channel 50 in connection to which the leading to the pressure chamber 8.4 compressed air connection line R6 is connected, so that the compressed air can flow into this pressure chamber 8.4.
  • In order to move the piston 8.2 of the pneumatic cylinder unit 8, it is necessary that the other pressure chamber 8.3 is vented. This is done in such a way that through the control channel 47, the adjoining connecting channel 47.1 and the mouth 47.2 compressed air flows into the valve chamber 45 'above the valve body 38', which is thereby pressed down, whereby the sealing ring 38.4 'of its valve seat 44th 'is moved away. Characterized a connection between the pressure chamber 8.3 and below the seal piston 38.5 'located portion of the valve chamber 45' is prepared by the leads L6 and 50 ', so that the pressure chamber is 8.3 vented by the venting to the valve chamber 45' vent passage 46 '.
  • In order to prevent a sudden pressure drop in the pressure chamber 8.3, the venting channel 46 'corresponding to the throttle L10 of FIGS. 1a and 1b associated with an exhaust throttle (not shown). The same applies to the vent channel 46th
  • After release of the button L9, the lower valve body 36 is pressed by the return spring 36.4 down, so that the sealing ring 36.3 is pressed against the valve seat 40.
  • Since after release of the button R9 the compressed air supply through the vent channel 47, 47.1 and 47.2 omitted in the valve chamber 45 'above the valve body 38', this valve body 38 'of the return spring 36.4' moved back up so that the sealing ring 38.4 'against the valve seat 44 'is pressed.
  • This will be the above in conjunction with the FIGS. 1a and 1b described automatic latching of the pneumatic cylinder 8 causes.
  • On the one hand to be able to adjust the valve body 36 of the valve unit shown on the right and thus the sealing ring 36.3 against the valve seat 30 and on the other hand to move the valve body 38 'of the valve unit shown on the left and thus the valve seal 38.4' to rest against the valve seat 44 ', It is necessary to reduce existing in the channel system 35, 47, 47.1 and 47.2 existing compressed air cushion. For this purpose, the ventilation system described above in connection with the button L9 at rest serves between the channel 35 and the environment.
