Definitions
- the invention relates to a valve with AND function in which a movable relative to a valve housing valve member controls the fluid connection between two inputs and an output, wherein its switching position depends on the pressure difference of the pending at the two inputs fluid pressures, such that at the same input pressures at least one input is connected to the output, and wherein the valve member can assume two mutually opposite end positions, in which it releases one of two associated with the outlet NEN housing-fixed first passages and at the same time shuts off the other first passage.
- a valve equipped with such features is known from the product catalog "Der Pneumatic-Katalog 97/98", edition 97/98, 33rd edition, Festo AG & Co., page 11.5 / 10-2.
- the valve has one output and two inputs, with pressure at the output whenever both inputs are simultaneously supplied with fluid pressure. At the same input pressures, the switching position is indifferent and the output is connected to only one or simultaneously with both inputs. If there is a pressure difference on the input side, the lower pressure always reaches the output.
- DE 22 51 963 A discloses a logic valve with one input and two outputs.
- the pressure medium flowing through the constantly open inlet is alternately discharged through the two outlets, the change always taking place when the inlet pressure decreases to zero or decreases by a predetermined value.
- the valve according to the invention allows a pressure medium through to the output when the same input pressure is present at the two inputs. If the input-side pressure difference exceeds a limit value defined by the application means, the output is disconnected from both inputs. This is done by the fact that the valve member shuts off on the one input the associated housing-fixed first passage and on the other hand, at the same time, the other inlet associated with the second passage on the one of the movable passage members. As long as an input-side pressure difference occurs that does not exceed the predetermined limit value, the valve member separates by interaction with the corresponding passage member only the lower input pressure having inlet, so that the output is still supplied from the other input with the higher input pressure.
- the valve can be used, for example, as a safety valve, whereby it performs a logic function and only outputs a signal at the output, as long as a certain pressure difference is not exceeded on the input side.
- the valve can also be used, for example, to control the synchronization to control two of the two inputs upstream control valves. An output signal is then only generated if the two control valves generate equal high pressure signals within a predetermined tolerance range.
- a first housing seat fixed to the housing is assigned to each of the two first passages, which is opposed in each case by a first sealing surface arranged on the valve member. In each of the two end positions, the first becomes one
- a respective first sealing surface and a second sealing surface are arranged in pairs on two spaced apart closure plates of the valve member.
- the passages are in particular arranged such that in each case a first passage fixed to the housing and a second passage arranged on a passage member are fluidically connected in series.
- the basic position of the passage members is expediently defined in each case by a stop surface arranged on the valve housing, to which the assigned passage member is pressed by the loading means.
- valve member is in the actuating direction axially between the two passage members, is thus flanked by these so expediently on axially opposite sides.
- the passage members are expediently ring-shaped to form the second passage associated therewith. You can be slidably mounted in the valve housing in the manner of pistons. Conveniently, they are arranged coaxially with the valve member.
- Each passage member conveniently carries a seal over which it is under guaranteeing its displaceability in lo-lasting sealing contact with the valve housing.
- a membrane which is in each case statically attached to the passage member and the housing, to be provided as a sealing element.
- the loading means are expediently in each case one compression spring device, in particular of a mechanical type.
- a gas spring in particular an air spring, would also be conceivable.
- FIG. 1 shows the valve in a switching position which simultaneously connects both inputs to the output
- FIG. 2 shows the valve in a switching position in which the inlet side is at a pressure difference which is still below the limit value and consequently the outlet is connected to the inlet leading to the higher pressure. is separated from and from the lower pressure leading input, and
- FIG. 3 shows a switching position in which the valve member is displaced into one of its two possible end positions as a result of a pressure difference exceeding the limit value, and the output of both inputs is thereby disconnected.
- valve The designated overall by reference numeral 1 valve is designed as a slide valve and has a schieberarti- loosely, elongated valve member 2, which is arranged in the interior of a valve housing 3 and there can perform a direction indicated by a double arrow linear switching movement 4 in the direction of its longitudinal axis 5.
- an elongated recess 15 is formed, whose longitudinal axis 7 coincides with that (5) of the valve member 2.
- the valve member 2 is received in the recess 6.
- the recess 6 includes a central portion 8, in which a leading to an externally accessible output A leading
- first passage 14a, 14b 25 axially oriented first passage 14a, 14b is defined.
- Each of these two first passages 14a, 14b is framed by a first valve seat 15a, 15b which points axially to the adjoining intermediate section 13a, 13b and which is formed on the valve housing 3.
- the first two valve seats 15a, 15b point in the axial direction of the longitudinal axis 7 in opposite directions.
- Each intermediate section 13a, 13b is adjoined in the direction of the longitudinal axis 7 by an end section 16a, 16b of the recess 6 on the side opposite the middle section 8.
- the end section 16a, 16b has, at least in the region directly adjoining an intermediate section 13a, 13b, a larger cross-section than the adjoining intermediate section 13a, 13b, so that an annular step is formed, which is one for the respective end section 16a, 16b facing annular abutment surface 17a, 17b defined.
- the one, first end portion 16a is permanently connected via a first input channel 18a to a first input E1 formed on the valve housing 3.
- the opposite second end section 16b communicates via a second input channel 18b with a second input E2, which is independent of the first input E1, on the valve housing 3.
- each passage member 23 a, 23 b is movable in the direction of the switching movement 4 relative to the valve housing 3. As an example, it is guided axially displaceably on the inner peripheral surface 24 of the associated end section 16a, 16b, comparable to a piston element.
- annular seal 25 arranged in the region of its outer circumference, each passage member 23a, 23b is sealed off from the valve housing 3 independently of the currently occupied axial position.
- the passage member 23a, 23b is arranged in the end portion 16a, 16b such that it always comes to lie between the adjacent intermediate portion 13a, 13b and the junction region of the inlet channel 18a, 18b opening into the associated end portion 16a, 16b.
- each input E1, E2 is connected to the second passage 22a, 22b axially passing through the passage member 23a, 23b, independently of the current displacement position of the associated passage member 23a, 23b.
- the second passage 22a, 22b passes through the passage member 23a, 23b in particular centrally, so that the latter is annular. It is arranged coaxially with the valve member 2, wherein the valve member 2 is placed axially between the two passage members 23a, 23b.
- Each second passage 22a, 22b is framed on the end face facing the intermediate section 13a, 13b by a second valve seat 26a, 26b formed on the passage member 23a, 23b. The latter can thus move together with the associated passage member 23a, 23b in the direction of the Umschaltbe- movement 4 relative to the valve housing 3.
- the valve member 2 is provided in the areas located within the intermediate sections 13a, 13b, each with a closure plate 27a, 27b.
- This closure plate 27a, 27b is, for example, a ring element which consists of a sealing material, in particular made of rubber-elastic material, and which is fastened so as to protrude radially on an elongated base body 28 of the valve member 2 which is made, for example, of metal or a hard plastic material.
- Each closure plate 27a, 27b carries at its opposite end faces two axially facing away from each other sealing surfaces, on the one hand to the first valve seat 15a, 15b facing first sealing surface 32a, 32b and on the other a second valve seat 26a, 26b facing the second sealing surface 33a, 33b.
- the two first sealing surfaces 32a, 32b face each other, the two second sealing surfaces 33a, 33b point away from each other in the direction of the switching movement 4.
- loading means 34a, 34b housed, each of which between the valve housing 3 and the associated passage member 23a, 23b are effective and bias the latter into a, for example, Figure 1 apparent basic position in which the passage member 23a, 23b at the associated stop surface 17a, 17b abuts.
- the urging means 34a, 34b thus push the passage member 23a, 23b in each case in the direction of the valve member 2 against the associated housing-fixed stop surface 17a, 17b.
- the mutual urging means 34a, 34b are formed independently of each other. They act on the associated passage member 23a, 23b in a yielding manner, each with a biasing force FB.
- the urging means 34a, 34b are each formed by a mechanical compression spring device, for example by a helical compression spring extending axially between the associated passage member 23a, 23b and an end wall 35a, 35b of the valve housing 3 axially opposite the end portion 16a, 16b, sealing the end portion 16a, 16b axially extend.
- the magnitude of the loading force FB depends on the design of the compression spring device. If required, adjusting means may be provided with which the bias of the loading means 34a, 34b can be varied in order to specify the loading force FB as desired.
- the loading forces FB exerted on the two passage members 23a, 23b by the urging means 34a, 34b are expediently the same.
- an air spring device could also be used, in particular on the basis of an enclosed air volume.
- the valve member 2 passes through the middle section 8 and projects into the adjoining intermediate sections 13a, 13b and, in the case of a corresponding switching position, even a little further into the adjoining end section 16a, 16b.
- a fluidic pressure medium can be fed in via the two inputs E1, E2, wherein the valve 1 is expediently operated with compressed air. But other media are also possible.
- the valve member 2 is acted upon from opposite sides of each of the two inputs via the inputs E, E2 fed pressure medium.
- the here relevant frontal Beaufschlagungs vom the valve member 2 are the same size and at 36a, 36b marked.
- the pressure medium fed to the inlet El acts with a first inlet pressure PEI in the one direction of actuation on the valve member 2, while the pressure medium fed via the second input E2 acts on the valve member 2 in the opposite direction with a second inlet pressure PE2.
- the present at the output A output pressure PA acts in both directions of actuation on the valve member 2, wherein the acted upon by him surfaces are also the same size, so that in this way there is a pressure force compensation.
- the respective switching position of the valve member 2 and thus of the valve 1 is predetermined by the input-side pressure difference between the first and second input pressure PEI, PE2.
- the valve member is acted upon in the direction of the lower inlet pressure by a resulting switching pressure dependent on the input-side pressure difference.
- the first and second valve seats 15a, 15b, 26a, 26b and the first sealing surfaces 32a, 32b and second sealing surfaces 33a, 33b are matched in their design and arrangement such that when one of the second sealing surfaces 33a or 33b on the second Valve seat 26a, 26b of a located in the basic position passage member 23a, 23b rests, all other sealing surfaces are lifted from their associated valve seat.
- One of these two possible intermediate positions of the valve member 2 can be seen from FIG.
- valve member 2 If a sufficiently high actuation force acts on the valve member 2, it can be displaced even further beyond an intermediate position (FIG. 2) into an end position.
- This end position is defined by the fact that the valve member 2, with the first sealing face 32a or 32b pointing in the switching direction, comes into contact with the first valve seat 15a, 15b opposite to it, whereby the associated first passage 14a or 14b is shut off.
- These end positions are further distinguished by the fact that the valve member 2, from the basic position, has the passage member 23a or 23b located upstream of it in the actuating direction. has deflected against the FB acting on it a bit far.
- the deflection is caused by the second sealing surface 33a or 33b currently oriented in the direction of actuation, which exerts a corresponding thrust force 37 on the opposing second valve seat 26a or 26b and thus on the associated passage member 23a, 23b.
- the second passage 22a or 22b of the passage member 23a or 23b pushed back thereby is closed in this case.
- the counterforce force responsible for the sealing effect is supplied by the application force FB acting on the passage member 23a, 23b.
- FIG. 1 One of the two possible end positions of the valve member 2 is illustrated in FIG.
- the valve is used as a safety valve or as a logic valve which outputs a pressure medium fed to the output A only if the pressure difference between the simultaneously present at the two inputs El, E2 input pressures PEI, PEI not a predetermined limit exceeds.
- the valve shuts off the output A from both the first input E1 and the second input E2.
- the responsibility for the switching characteristic of the valve limit value of the input-side pressure difference is determined by the biasing force FB of the biasing means 34a, 34b.
- the valve member 2 switches into an end position shutting off the two inputs E1, E2 from the output A when the resulting actuating force acting on the valve member 2 on the basis of the input-side pressure difference is greater than the acting in the opposite direction. force FB of one or the other Beaufschlagungsstoff 34a, 34b.
- FIG. 1 shows an operating state with identical input pressures PEI, PE.
- the valve element 2 here assumes an inactive switching position which can vary, either-as can be seen from the flow arrows shown-at the same time from both inputs E1, E2 pressure medium to the outlet A flows or from only one of the two inputs El or E2.
- the output A is also supplied by the higher of the two input pressures PEI, PE2 if, on the input side, there is a pressure difference which has not yet exceeded the set limit value.
- Such an intermediate position is shown in FIG 2. Due to the here with respect to the second input pressure PE2 slightly higher first input pressure PEI, the valve member 2 has the second passage 22b of the second input E2 associated passage member 23b shut off, at the same time the first input El assigned, fluidly connected in series first and second passages 14a, 22a are open to pass the higher first input pressure PEI to the output A.
- valve member 2 In this intermediate position, the valve member 2 is supported on the passage member 23b associated with the second input E2, which is fixed in its basic position by the associated urging means 34b.
- the valve member 2 can suppress the passage member 23b assigned to the lower inlet pressure PE2 while overcoming the loading force FB acting on it.
- This displacement movement en- det, when the valve member 2 abuts the first valve seat 15a.
- both the housing-fixed first passage 14a is shut off and the second passage 22b formed on the displaced passage member 23b.
- the connection between the outlet A and each of the two inputs El, E2 is interrupted.
- This described mode of operation is possible in both directions of movement of the valve member 2 and depends only on which of the two input pressures El, E2 is greater than the other.
- valve 1 it is ensured that the output A is completely blocked by the inputs El, E2 when an input-side pressure difference of a predetermined level is reached, but that the output A reaches the higher of the two currently present values until the limit value is reached Input pressures is supplied.
