Definitions
- the invention relates to a gas flow monitor for automatically shutting off gas lines when an impermissible increase in flow occurs.
- Such gas flow monitors which are used in pipelines, such as in front of gas fittings, gas appliances, etc., are available in a variety of designs. They serve to interrupt the gas supply when the gas consumption increases above a predetermined value.
- WO 92/01184 describes a gas flow monitor of the type mentioned at the outset, which is called a safety closing device and which closes the pipeline system in the event of damage, but without causing the supply line to be closed prematurely when a
- a valve is designed as a poppet valve.
- the valve body is attached to a valve stem, which is mounted on both sides in sliding bearings in the axial direction of the valve against the force of a spring.
- the valve disk interacts with a valve seat located in one of two ring disks, the ring disks simultaneously serving as bearings for the slide bearings already mentioned above.
- the washers are provided with recesses or openings. Since a defined value of the pressure loss at the open valve is assigned to each flow value, a shift of the operating point on the pressure loss characteristic or / and a shift of the pressure loss characteristic of the safety closing device is necessary in order to be able to precisely adapt the closing flow to the type, nature and quantity of the consumers.
- the spring force of the spring and / or the closing path of the valve can be adjusted.
- a nut is provided at the free end of the valve stem, which is screwed onto a thread located on the valve stem.
- An adjusting device arranged in the area between the two sliding bearings, for example formed by a second nut, is used to adjust the spring force.
- shut-off valve is known from GB - PS 556,863.
- This shut-off valve consists of a one on both sides
- Tubular housing with connection thread Arranged in the housing is an annular disk provided with openings, which has a sliding bearing in the center for a longitudinally movable valve stem, which has at one end a valve body which interacts with a valve seat located in the housing.
- a compression spring which is supported on the one hand on the valve body and on the other hand on the annular disc, holds the valve body in the open position until the set closing flow is reached.
- the setting of the spring force is changed in this version by changing the screwing depth of the valve stem into a hood and thus changing the installation length of the spring.
- a valve described in US Pat. No. 3,794,077 has a similar structure.
- a compression spring which is located on the one hand in a housing and also has openings, and on the other hand is supported on a nut screwed onto the valve stem, holds the valve body in the open position until the set closing flow is reached.
- the invention is based on the problem of developing a gas flow monitor of the type mentioned, in which the setting / changing of the closing flow is possible without design changes, such as the use of different springs depending on the desired closing flow, and thus also after production , In particular, it should be made possible for the closing flow to also be set outside the production facility, advantageously only at the time of installation.
- the problem is solved in that a spacer is arranged on the input guide, which forms a stop for the closing body in the open position of the gas flow monitor.
- each latching area has different latching positions, the respective engagement of which can be achieved by rotating the spacer by an angle of rotation assigned to the latching positions, wherein in
- the position of the stop for the closing body in the open position can be changed in the longitudinal direction of the pin.
- an embodiment in which the spacer is held captively on the input guide proves to be advantageous, in that it has a resilient lip assigned to each web of the input guide, which allows the web to snap over, whereas a pin assigned to each web of the input guide prevents pressing out is.
- FIG. 1 shows a gas flow monitor in a sectional view in the open position.
- FIG. 2 shows a view A of the gas flow monitor from FIG. 1.
- FIG. 3 shows a view of the spacer from FIG. 1.
- FIG. 4 shows a view B of the spacer from FIG. 3.
- the exemplary embodiment of a gas flow monitor according to the invention shown in FIG. 1 has a tubular housing 1 which can be pressed into a gas line (not shown).
- the housing 1 is advantageously provided with an insertion slope 2.
- the housing 1 has a circumferential groove 3, which serves as a receptacle for an O-ring, not shown. It goes without saying that a different connection is also possible.
- the housing 1 On the input and output sides, the housing 1 is provided with a recess 4. Between the two turns 4, the housing 1 has a constriction 5, which is designed as a valve seat 6 on its side facing the inlet.
- An input guide 7 or output guide 8 is pressed into the recess 4 on the input or output side.
- these are advantageously designed as shaped sheet metal parts which have three radial webs 10 which are evenly distributed over the circumference (FIGS. 2 and 4).
- the input guide 7 is provided in the center with a bearing point 9 for a pin 11, the second bearing point 12 of which is formed by an adjusting element 13 screwed into the center of the output guide 8.
- the pin 11 is guided to be longitudinally movable, on which a closing body 14 is fastened, for example by means of an interference fit.
- the closing body 14 has an annular shape Receptacle for an O-ring 15 serving as an elastic sealing element.
- a closing spring 16 is supported on the adjusting element 13 and holds the closing body 14 in its open position with its other end. The open position is determined by the stop of the closing body 14 on a spacer 17 fastened on the input guide 7, which has stop points 18 for this purpose.
- the spacer 17 is provided with latching areas 19 assigned to each web 10, which reach behind the webs 10 (FIG. 2).
- a resilient lip 20 assigned to each web 10 allows the web 10 to snap over when the spacer 17 is mounted.
- the position of the web 10 before the snap-over is shown in FIG. 3.
- the web 10 is prevented from being pressed out of the spacer 17 by means of pins 21 also assigned to the webs 10.
- a spring 22 which is supported on the one hand on the side of the input guide 7 facing away from the closing body 14 and on the other hand on the spacer 17, the spacer 17 is held in its position.
- each latching area 19 has different latching positions, three in this exemplary embodiment, which are realized by correspondingly rotating the spacer 17.
- the webs are located in the latching plane E1, which is advantageously formed by the pin 21.
- the two other locking levels are identified in FIGS. 2 and 3 by E2 and E3 for at least one web 10 each.
- the position of the stop points 18 for the closing body 14 is thus changed in the longitudinal direction of the pin 11 as a function of the selected latching position.
- the respective setting can be recognized immediately by means of markings 24 applied to the spacer 17.
- each individual locking level which serves as an anti-rotation device 23 due to the action of the spring 22. Only by an external force acting against the spring 22 is the spacer 17 moved so far in the longitudinal direction that each web 10 is outside the action of the anti-rotation device 23.
- the gas flow monitor is set at the factory to a certain value of the closing flow by adjusting the adjusting element 13 and using appropriate adjusting and testing devices.
- the position of the closing body 14 in the open position can now be changed in order to set the desired closing flow by using the corresponding latching position of the spacer 17.
- the pressure loss characteristic curve of the gas flow monitor and, depending on the spring constant of the closing spring 16, also the working point are shifted by a more or less large amount, as a result of which the closing flow rate is changed.
- the gas flow monitor is then installed in a gas line in such a way that the flow direction of the gas indicated by arrows in the illustration in FIG. 1 is maintained. Normally, it is then in the position shown in FIG. 1.
