Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a support device for supporting a water meter for measuring water usage.
[0002]
[Prior art]
The water meter installed in the middle of the water pipe is required to be replaced after the elapse of a predetermined period stipulated by the Measurement Law. Therefore, various connecting means for connecting and removing this water meter in the middle of piping have been proposed.
[0003]
Specifically, for example, Japanese Examined Patent Publication No. 6-102910 relates to a connection device for exchanging a deep water meter such as in a cold region, and a water meter unit detachably attached to a base portion. In this base portion, the connection portion is provided on a pair of plates and the plate is supported by three stays. In addition, Japanese Utility Model Publication No. 3-46300 discloses a pipe connection portion before and after a pipe. , Provided in a connection port provided integrally with a frame on which the water meter is placed, and this frame is provided at a lower portion in the length direction of the water meter.
[0004]
Further, Japanese Patent Laid-Open No. 9-125469 discloses a method for holding a sealing material of a connecting portion, which forms a concave groove on a joint surface with a water meter, and stores a sealing member in the concave groove. It is a thing.
[0005]
[Problems to be solved by the invention]
However, these conventional methods for connecting water meters have various problems.
For example, in the above-mentioned Japanese Patent Publication No. 6-102910, in order to give the overall strength with three stays having a pair of plates, not only the number of parts is increased and the cost is increased, but also the width of the apparatus as a whole is increased. There was a problem of getting bigger.
[0006]
In addition, in areas called semi-cold regions, it is necessary to cover the water meter with a heat insulating material in order to easily protect the water meter from freezing. There was also a problem that it was inevitably covered with a heat insulating material, and eventually occupied a large space as a whole.
[0007]
On the other hand, since Japanese Utility Model Publication No. 3-46300 is an apparatus in which a connecting portion and a frame are provided integrally, when a large water pressure is generated in the measuring device, the measuring device tends to be separated from the connecting portion. Therefore, there is a problem that bending is applied to the frame, the connection part is inclined, and water leaks easily, and furthermore, since the structure is kept horizontal by contacting the frame and the water meter, it is difficult to attach the heat insulating material. Also had.
[0008]
Japanese Patent Laid-Open No. 9-125469 has a problem that the sealing member in the sealing mechanism is easily dropped from the concave groove, and it is conceivable that the dovetail groove is used to make it difficult to drop off. In this case, there is a problem that the sealing surface is easily damaged when the sealing material is replaced.
[0009]
In addition, in the conventional water meter connection device, the inlet pipe and the outlet pipe are always arranged on one axis. For example, in a narrow pipe space, there is no room for piping on one axis. Installation was difficult.
[0010]
The present invention has been developed in view of the problems of the connection device in the conventional water meter. The object of the present invention is to save the water meter support device in a small space. It is possible to contribute to space saving, and the strength is sufficient, so that a compact device can be manufactured, the water meter can be reliably replaced with one-touch operation, and the heat insulating material can be easily attached. .
[0011]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the present invention is a metering device support device that supports a metering device in a replaceable manner, and includes a substantially rectangular frame that penetrates up and down. primary, are opposed to the secondary-side connector attached, one connector may Rutotomoni provided a support unit for advancing and retracting the manually inner end of the substantially cylindrical holding portion which is inserted into the opposing piece, the holding portion The outer end is connected to a flow passage port of a pipe connection body fixed to the mounting surface on the outer side of the opposing piece, and this pipe connection body is provided with a pipe connection port in a direction orthogonal to the flow direction of the water meter, It is a support device for a water amount device that can change the connection direction of the pipe connection port by rotating the pipe connection body with respect to the mounting surface .
[0013]
In addition, a cylindrical stopper is provided on the inner periphery of the end surface of the support portion, with a step portion into which the annular seal material protrudes and fits, and the seal material is fitted into the step portion and the inner periphery of the seal material is fitted into the support portion. Since it has been pressed, it is possible to prevent the sealing material that seals the end surface of the support portion and the connection end portion of the water meter from falling off, and the end surface can always be reliably sealed.

Further, the entire periphery of the apparatus may be covered with a heat insulating material, and these are optional depending on the implementation.
[0032]
Next, the operation of the above embodiment will be described.
There is no restriction on the piping space, and as shown in FIG. 1, when the main water pipe A and the branch pipe B extending to each door are piped in a straight line, as shown in FIG. Plugs 28 and 48 are connected to the pipe connection port 23 below the primary side connector 10 serving as the inlet of the flow path perpendicular to the road direction and the pipe connection port 43 below the secondary side connector 30 serving as the outlet. And the primary and secondary side connectors 10 and 30 are fixed to the mounting surface 1b of the frame body 1 with bolts 4 respectively. In this case, the pipe connection port 22 (hereinafter referred to as an inflow port) of the primary side connector 10 serving as an inflow port of the present apparatus and the pipe connection port 42 (hereinafter referred to as an outflow port) of the secondary side connector 30 serving as an outflow port. ) Is located on the same axis as the flow path of the water meter M, regardless of which direction the other pipe connection ports 23 and 43 face, so that a straight flow path is always formed. Accordingly, the direction of the primary and secondary side connectors 10 and 30 is fixed, for example, by fixing the primary side connector 10 in a direction in which the handle 27 of the pipe connector 20 of the primary side connector 10 is easy to operate (upward in the figure). The sex is not particularly limited.
[0033]
In addition, when there is a restriction in the piping space and the water main A and the branch pipe B extending to each door cannot be piped in a straight line, as shown in FIG. Plugs 28 and 48 are screwed into the pipe connection port 22 on the left side of the primary side connector 10 that becomes the inlet of the flow path on the straight line and the pipe port 42 on the right side of the secondary side connector 30 that becomes the outlet. The pipe connection body 20 of the primary side connector 10 is rotated 90 ° clockwise from the state of FIG. 1 (see FIG. 7), and the pipe connection body 40 of the secondary side connector 20 is connected. Are rotated 90 ° counterclockwise and fixed to the mounting surface 1b of the frame 1 with bolts 4 respectively. In this case, a pipe connection port 23 (hereinafter referred to as an inflow port) of the primary side connector 10 serving as an inflow port and a pipe connection port 43 (hereinafter referred to as an outflow port) of the secondary side connector 30 serving as an outflow port are: In both cases, a narrow U-shaped channel is formed facing the upper side of FIG. 6, that is, the back side, so that it is possible to construct even a narrow pipe space. In addition, the directionality at the time of fixation of the primary side and secondary side connector 10 and 30 is not limited to this, It can select suitably according to the position of the water main A or the branch pipe B.
[0034]
Then, the water main A is connected to the inflow port 22 or 23, the branch pipe B is connected to the outflow port 42 or 43, and the base 2 of the frame 1 is placed at an appropriate position on the floor surface or using bolts. Fix it.
[0035]
Next, the connection end portions 51 and 52 of the water meter M are placed on the receiving portions 12c and 32c provided in the support portions 12 and 32 of the primary and secondary side connectors 10 and 30, respectively. The flow channel and the flow channel of the water meter M are positioned on the same axis, and the rib 50 of the water meter M is fitted into the concave detent portion 3 a formed on the holding member 3. Check and prevent the water meter M from rotating or slipping. At this time, since the receiving portions 12c and 32c on which the connection end portions 51 and 52 are placed are formed in a substantially semi-cylindrical shape, it is easy to place them. Further, the handle 15 of the primary side connector 10 is turned to advance the support portion 12 inward in FIG. 3 from the holding portion 11, and the water meter M is clamped and held between the end faces of both the support portions 12 and 32. The end surfaces of the support portions 12 and 32 and the end surfaces of the connection end portions 51 and 52 of the metering device M are sealed in a liquid-tight manner with the sealing materials 17 and 37 attached to the end surfaces, and the metering device M is connected to this apparatus.
[0036]
Thereafter, the flow path to the water main A is opened, and further, the handle 24 provided on the pipe connection body 20 of the primary side connector 10 is rotated in an appropriate direction to rotate the ball 24, and the inflow port 22 or 23 and the flow path port 21 is communicated (see FIG. 3).
[0037]
On the other hand, when removing the water meter M from the apparatus, the handle 27 of the pipe connector 20 is rotated in an appropriate direction to rotate the ball 24 to close the flow passage port 21, and between the water main A and the water meter M. After closing the flow path, the handle 15 of the primary side connector 10 is turned to retract the support portion 12 into the holding portion 11 to remove the force that pinched the water meter M, and the water meter M is detached. enable.
[0038]
In this case, when the handle 15 is turned, the support 12 is inserted into the restricting groove 12a provided on the outer peripheral surface of the pin 13 protruding from the holding part 11, the rotation is restricted, and the screw screwed into the cylindrical part 15b of the handle 15 Since 16 is inserted into the annular groove 11a of the holding portion 11, the support portion 12 that can move forward and backward without moving the handle 15 relative to the holding portion 11 advances and retreats.
[0039]
In the above embodiment, the support portion is advanced and retracted by rotating the handle. However, the support portion may be manually advanced and retracted using a cam, a link, or the like. Moreover, although the case where the piping which has rigidity was used was demonstrated, since the base 2 provided in the lower part of the frame bodies 1, such as casting, can be fixed to the floor surface F, it is like flexible piping, such as resin and a flexible tube. It is also possible to use piping that is easy for piping work.
[0040]
【The invention's effect】
As is apparent from the above, the present invention includes a substantially rectangular frame that vertically penetrates, and the primary and secondary side connectors are attached to the opposing pieces of the frame so as to face each other, and the handle is attached to one of the connectors. Since a support part that moves forward and backward manually is provided, sufficient strength can be obtained, and the width of the device can be narrowed, even if a space for inserting a heat insulating material between the water meter and the frame is adopted This contributes to space saving and compactness without increasing the overall width.
[0041]
In addition, since the present invention has formed the detent portion in which the rib of the water meter is fitted on the middle lower side of the frame body, there is no possibility that the direction of the water meter will be mistaken when the water meter is attached. The strength of the body itself can be improved, and the device itself can be made rigid at low cost. Furthermore, by providing a mounting base on the frame, the water meter can be fixed securely. It is also possible to use materials that are easy for piping work, such as resin and flexible tubes, for piping.
[0042]
Furthermore, it is possible to prevent the annular sealing material from inadvertently dropping from the step portion, and it is easy to replace and inspect the sealing material when replacing the water meter regularly. Becomes better.
[0043]
The primary, since to be able to change the position Mounting the pipe connection port of the secondary-side connector, very conveniently adaptable to the construction site, high commercial value, specifically, The water meter is installed in front of the space to read the measurement, but even if the piping is installed from the back side of the space, the orthogonal pipe connection port is rotated 90 ° to the back side, for example. Therefore, connection construction can be performed even in a small occupation area, and piping is often laid out symmetrically in condominiums and the like, but even in such a case, the connection part is 180 ° without changing the parts. By rotating, there is a useful effect such as being able to cope with the flow direction from either the left or right side.
