Definitions
- the invention relates to a pressure relief valve according to the preamble of the independent claim.
- Pressure relief valves are used, for example, in gas refueling systems needed with which mobile pressure vessels such.
- Such Gas refueling systems typically include a stationary, with compressed gas-filled storage tank and a Dispensing device to this storage container with the mobile Connect the storage container so that the gas from the storage container in can flow the mobile storage container.
- the pressure relief valve solving these tasks is characterized by the features of the independent claim.
- a pressure relief valve is therefore also proposed an inlet and an outlet for a fluid, with a valve body so interacts with a valve seat that it reaches when a Limit pressure is a flow connection for the fluid between the inlet and opens or closes the outlet, as well as with a spring element, which acts on the valve body and loads it, also a A container for a liquid is provided, which is arranged and is designed so that the liquid due to its thermal expansion the spring element caused stress on the valve body and thus the Limit pressure changes depending on the temperature of the liquid.
- the liquid in the container changes due to its thermal expansion their volume. For example, if the temperature of the liquid rises, it decreases their volume too. This increase in volume makes the spring element compressed, which causes the loading of the spring element Valve body increased. This also increases the limit pressure at which the pressure relief valve closes or opens. Conversely, reduces the Liquid its volume with a decrease in temperature. This will the spring element slightly relaxed and the load on the valve body is reduced. Consequently, the limit pressure at which the valve drops closes or opens. Thus, the pressure relief valve changes automatically its limit pressure depending on the temperature, which makes it easier How a temperature-dependent pressure limitation is made possible.
- the container for the liquid is preferably a hollow cylinder designed and includes a movable plunger, the one hand is supported on the spring element, and on the other hand from the pressure of the Liquid is applied.
- the inner wall of the Hollow cylinder the pressure piston that is the inner diameter of the Hollow cylinder is essentially equal to the diameter of the Pressure piston.
- the movable pressure piston forms a boundary surface of the volume of the liquid inside the hollow cylinder Available.
- a provided inner cylinder which is arranged coaxially in the hollow cylinder, wherein the pressure piston is provided in the inner cylinder and from this is guided, and wherein the inner cylinder has an opening, so that the liquid can act on the pressure piston.
- the cross-sectional area of the pressure piston is preferably larger than that effective cross-sectional area of the Valve body. This measure has the advantage that the pressure of the Liquid in the container can be chosen significantly smaller than that Limit pressure at which the valve closes or opens.
- Pressure relief valves are a means for thermal contact between the fluid and the liquid provided so that the liquid in the Container is at substantially the same temperature as the fluid.
- a pressure line can be provided in the container, which is surrounded by the liquid and through which the fluid flows through. Then takes on the principle of the heat exchanger Liquid at the same temperature as the fluid. Hence the changes Liquid depending on the limit pressure of the pressure relief valve from the current temperature of the fluid.
- the container comprises adjustment means for that for the liquid change available volumes.
- adjustment means are used for adjustment or calibration of the pressure relief valve.
- the Adjustment means include, for example, one on the inside diameter of the Hollow cylindrical container adjusted adjusting piston, its position over an adjusting screw is changeable. By turning the adjusting screw the adjusting piston can be moved along the longitudinal axis of the hollow cylinder move, whereby the liquid is available Volume changes.
- the position of the adjusting piston and so that the tension of the spring element changed until it to this Limit pressure belonging to the reference temperature is reached.
- the container preferably contains a liquid in the operating state, the thermal expansion coefficient of which is at least 10 -4 K -1 , in particular at least 5.10 -4 K -1 .
- An oil which typically has such volume expansion coefficients is particularly preferably used as the liquid.
- the limit pressure is substantially linear from the temperature of the Liquid dependent, the slope in particular 1.5 bar / K to 2 bar / K is because this slope is the pressure-temperature behavior of natural gas corresponds.
- the increase in the limit pressure with the temperature can be the pressure limiting device according to the invention in a simple manner about the amount of liquid in the container to the desired value to adjust.
- the pressure relief valve is used in gas refueling systems for natural gas preferably set so that the limit pressure is 180 bar to 220 bar if the liquid in the container has a temperature of 15 ° C.
- the Pressure relief valve 1 comprises a valve housing 2 with an inlet 8 and an outlet 9 for a fluid.
- a spring-loaded valve body 3 is provided with a sealing surface 31 which in known way cooperates with a valve seat 4 that he at Reaching a limit pressure a flow connection for the fluid closes or opens between the inlet 8 and the outlet 9.
- Fig. 1 shows the pressure relief valve 1 in its open position.
- a spring element 5 for example a spiral spring, which acts on the valve body 3 and this with a spring force charged.
- the spring element 5 is supported on a ram plate 13, to which a plunger 12 connects, which against the end face of the Valve body 3 presses.
- the adjoining this end face as shown, the upper part of the valve body 3 is in a longitudinal bore of the valve housing 2 and sealed with an O-ring 14.
- valve body 3 by the spring element 5 stresses that a downward force is shown on the Valve body 3 acts, which wants to push it out of the valve seat 4.
- the fluid that is in the open position of the Pressure relief valve 1 flows from inlet 8 to outlet 9, a pressure on the valve body 3, the one shown upwards directed force on the valve body 3 causes which by the Counteracts force caused by spring loading. As long as the strength is through the spring load is greater than that caused by the fluid, that remains Pressure relief valve 1 in its open position.
- a container for a liquid connects to the valve housing 2, which is designed here as a hollow cylinder 6 with a longitudinal axis A.
- the Hollow cylinder 6 is made of a pressure-resistant material, typically one Made of steel.
- the lower end of the hollow cylinder 6 as shown is firmly connected to the valve housing 2, for example screwed.
- the Spring element 5 is arranged in the interior of the hollow cylinder 6 and extends itself in the direction of the longitudinal axis A.
- On the end of the spring element 5, the facing away from the valve body 3 is supported in the direction of the longitudinal axis A movable pressure piston 7, which is dimensioned so that it through the inner wall 61 of the hollow cylinder 6 is guided.
- an O-ring 14 for Sealing is provided between the Pressure piston 7 and the inner wall 61 .
- the interior of the hollow cylinder 6 is shown at its upper end limited by an adjusting piston 10, the diameter in essentially corresponds to the inner diameter of the hollow cylinder 6.
- the Adjusting piston 10 is provided with an O-ring 14 serving as a piston ring Provide seal.
- the adjusting piston 10 is with an adjusting screw 11 connected, which is guided in a threaded piece 11a and whose head protrudes the hollow cylinder 6. By turning the adjusting screw 11 the adjusting piston 10 move in the direction of the longitudinal axis A. After the pressure relief valve 1 in described later Way is adjusted or set, the adjusting piston 10 remains during the normal operation in a position fixed by the adjusting screw 11.
- This volume 15 is complete with a liquid, preferably an oil filled.
- the limit pressure of the pressure relief valve 1 thus depends on the Load from which the spring element 5 exerts on the valve body 3. If the outside temperature changes during operation, it changes also the temperature of the oil in the hollow cylinder 6, because the oil over the Wall of the hollow cylinder 6 with the outer space in thermal contact stands. For example, if the temperature of the oil increases, it expands Oil and pushes the pressure piston 7 downward as shown. As a result, the spring element 5 is compressed more, whereby the of the spring element 5 caused load on the valve body 3 increases. The limit pressure consequently rises, that is to say the pressure-limiting valve 1 closes only at a higher pressure. Conversely, the Outside temperature means that the oil also cools down and be there Reduced volume.
- the pressure relief valve according to the invention thus has the property that it automatically changes the limit pressure in the event of temperature fluctuations.
- the cross-sectional area B of the Pressure piston 7 larger than that acted upon by the pressure of the fluid effective cross-sectional area C of the valve body 3. This allows namely ensure a kind of hydraulic translation. Because the pressure of the Liquid applied a cross-sectional area B, which is larger than that effective cross-sectional area C, which is acted upon by the pressure of the fluid, is only clear on the liquid side, i.e. on the pressure piston 7 less pressure is required than on the fluid side to get that from the fluid the valve body 3 force to compensate. Less pressure in the hollow cylinder 6 is on the one hand for reasons of operational safety and Construction effort advantageous and also makes it easier to seal the Volume 15.
- the spring element 5 is preferably designed so that it is relatively soft is what is meant by the fact that the spring element 5 has a small spring constant having. This measure enables the closing interval or the opening interval, i.e. the period of time that the Pressure relief valve 1 required to move from the open position to the Shorten the closing position (or vice versa).
- this Spring element 5 for example a spiral spring, can be a small one Realize the spring constant by making the spiral spring as long as possible becomes.
- the pressure relief valve 1 is part of a gas refueling system with which a mobile pressure vessel, such as B. the reservoir of a gas powered motor vehicle with compressed natural gas is filled up to a final pressure.
- the fluid is in in this case natural gas.
- the pressure relief valve 1 is in one Dispensing device provided, by means of which the compressed natural gas a stationary storage container filled in the mobile storage container becomes.
- the pressure of the natural gas in the Storage tank about 200 bar based on a reference temperature of 15 ° C.
- the inlet 8 of the pressure relief valve 1 is with a pressure line connected, which on the other hand with the stationary storage container connected is.
- the outlet 9 is connected to the through a further pressure line connected mobile storage container.
- the task of Pressure relief valve 1 is the flow connection between the Seal inlet 8 and outlet 9 as soon as the pressure in the mobile Reservoir - and thus the pressure at outlet 9 - the final pressure for the Filling has reached, so that no more natural gas in the mobile Can flow reservoir.
- This final pressure is from the Depending on the outside temperature. It is, for example, 200 bar at 15 ° C.
- On typical value that describes the pressure-temperature behavior of natural gas - at least in the practical temperature interval of about -40 ° C to + 50 ° C - is a pressure increase of 1.6 bar at a Temperature increase of 1 K.
- Influence in the pressure relief valve 1 according to the invention mainly two factors the dependence of the limit pressure on the Temperature, namely the relative thermal Volume expansion coefficient ⁇ of the liquid in the container (in Fig. 1 is the container of the hollow cylinder 6), or more precisely the difference from the thermal expansion of the liquid and the thermal expansion of the Material from which the container is made, and secondly the amount of Liquid contained in the container.
- the thermal expansion coefficient ⁇ of the liquid is at least 10 -4 K -1 , in particular at least 5 ⁇ 10 -4 K -1 .
- the liquid is an oil that has a volume expansion coefficient of 7 ⁇ 10 -4 K -1 .
- the use of oil as a liquid also has the advantages that the oil lubricates the O-ring 14 on the pressure piston 7 and that less friction losses occur compared to other liquids.
- oil even with multiple temperature increases and decreases, there is practically no hysteresis in the limit pressure-temperature curve.
- the hollow cylinder 6 is made of steel, which typically has a relative linear thermal expansion ⁇ ⁇ 11 ⁇ 10 -6 K -1 , that is, the relative volume expansion of the steel is more than an order of magnitude smaller than that of the oil.
- the diagram in Fig. 2 shows the dependence of the limit pressure of the Pressure relief valve 1 from the temperature of the oil.
- On the vertical Axis p is the limit pressure in bar, on the horizontal axis T the temperature in ° Celsius. 2 is the substantially linear
- the dependence of the limit pressure on the temperature can be clearly seen (Straight G).
- the Measure the amount of oil in volume 15 of the hollow cylinder so that the slope the straight line G is 1.6 bar / K.
- other slopes of the straight line G for example through Change in the amount of oil in the hollow cylinder 6, can be realized.
- the pressure relief valve 1 now regulates the Limiting pressure automatically depending on the temperature.
- the pressure relief valve 1 closes at a limit pressure of 140 bar (see Fig. 2), that means Pressure relief valve 1 ends the refueling process at one Final pressure of 140 bar in the reservoir of the motor vehicle.
- the pressure relief valve 1 ends the outside temperature of 15 ° C Refueling process therefore only at 200 bar. So that enables Pressure relief valve 1 an automatic adjustment of the final pressure of the Refueling to the temperature.
- Fig. 3 shows a longitudinal section through a second embodiment of the inventive pressure relief valve. Below are just the Differences to the first embodiment explained. Otherwise the apply Explanations in connection with the first embodiment in analogously the same way for the second embodiment.
