Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a meter unit composed of a valve unit, a flow meter, a check valve unit, etc., which is carried by a frame so as to be portable in an integrated structure, and is installed in a commercially available meter box. The present invention relates to a unit frame in which a meter unit or the like can be set simply by fitting and end fitting, and a flow rate meter unit using the same.

[0002]

A mechanism such as a flow meter or a water faucet is inevitably provided in the middle of the water supply pipe, but the devices and mechanisms set in the middle of the pipe are valve mechanisms. And the like are often attached.

[0003] Regarding the flow meter, unless the valve unit is provided on the upstream side and the check valve unit is provided on the downstream side, the original flow measuring function cannot be exhibited.

Conventionally, the associated mechanisms constituting the unit as described above have been carried to the site as individual members, and the work of assembling the site has been performed. However, work in a site with a bad working environment takes time. Due to the problem of parts being lost or damaged, they have been unitized into an integral structure.

[0005] Due to such a tendency to form an integral structure unit, the applicant of the present invention has proposed a meter support box in which a flow rate meter is provided with a support for supporting an end of a valve unit and a check valve unit in a lower box of the meter box. (Japanese Patent Application Hei 10-31
7758), but when the valve unit and check valve unit are assembled as a meter unit into an integral structure using only the support box, it must be robust enough to withstand the pressing force from the meter and the water pressure of the internal water flow. There are problems that the weight of the box (meter box) increases and that a special support box must be used.

[0006] Further, in order to form an integral structure unit, a fitting mechanism of a meter end portion having a valve mechanism and a check valve mechanism built therein is provided at both ends of a support rod bent in a U-shape. Although the flow meter was fitted between the joints, the support rod functioning as a support frame that integrally supports the unit was linear, and was structurally unstable. There was still a problem with the robustness to withstand water pressure and the like.

[0007] Further, in the case where a flow rate meter or the like unitized in a unitary structure is stored in a support box (a box such as a meter), it cannot be simply fitted with a linear support rod. There is also a problem that a troublesome operation for eliminating the rattling and performing stable storage is required.

[0008]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has a structure in which a support frame for integrally supporting a unit is formed in an annular shape surrounding the unit so as to reduce the distance from the unit. It provides a supporting force that can structurally respond to the tensile force, pressing force, and deformation, and fits the shape of the outer diameter outside of the frame into the inside of the storage box or the upper box and the lower box of the storage box. It was formed in a shape to be sandwiched between, so that it could be simply fitted into a commercially available meter box.

Further, a fitting fitting portion having a fitting structure for fitting to the upstream end portion and the downstream end portion of the unit body to be internally fitted is provided on the frame, and the constituent members are integrally formed as a unit body. This is a unit frame that can be functionally connected to the structure.

[0010] Furthermore, using this unit frame, a valve unit is connected to an upstream end and a check valve unit is connected to a downstream end inside a frame having an outer shape fitted inside the meter box. At both ends of the measurement meter,
Both ends of the flow rate meter were fitted and fitted to the fitting portion provided on the frame body to constitute a flow rate meter unit.

[0011] With the above structure, the structural rigidity of the frame can be ensured, and the frame of the frame can be lightened as a hollow structure, and can be stored in the storage box very easily.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a unit frame main body, which is formed in an annular shape surrounding a flow rate meter unit A in which a valve unit a is connected to an upstream end and a check valve unit b is connected to a downstream end, and an upstream end and a downstream end are arranged. Fitting fitting portions 11 and 12 each having a fitting structure for fitting to the end of the valve unit a and the end of the check valve unit b are formed in the portions.

The fitting portions 11 and 12 are fitted to the end of the valve unit a and the end of the check valve unit b via adapter units 21 and 22 each having a hexagonal outer diameter. Hexagonal insertion holes 13 and 14 are formed. The lower part of the insertion holes is a spacer projection 15 for maintaining a space between the bottom plate of the storage box lower box 32 and the meter unit A, and the upper part is the upper side of the storage box 3. Joint piece 16 joined to the lower end fitting portion of box 31
Are formed.

By forming the outer diameters of the adapter units 21 and 22 and the shapes of the corresponding fitting holes into hexagons or at least squares, the lateral movement of the unit body to be fitted and supported is prevented. You.

The material of the unit frame body 1 is formed of a synthetic resin or a casting according to the type of the unit body to be fitted and supported and the setting environment of the storage box 3 for storing the unit body. Is formed so as to fit into the inside of the storage box or to be sandwiched between the upper box and the lower box of the storage box, and is reinforced by appropriate ribs 4 to form a hollow portion 41 to reduce the weight. To do.

The fitting unit 11 of the unit frame 1 configured as described above has an adapter unit
A valve unit a (ball stopcock unit) is fitted to the fitting 21, and an adapter unit 22 composed of a slider case 23 and a slider handle 24 is fitted into the fitting hole 14 in the fitting fitting part 12. Is being worn.

Inside the slider case 23, a fitting portion 25 for holding the end of the flow rate meter 2 at the end is provided, and a slider 26 for fitting the check valve unit b is fitted therein. The male screw 27 engraved on the inner surface of the slider case 23 is screwed with the female screw engraved on the inner diameter of the slider case 23 so that when the slider case 23 is rotated by the jig 5, the male screw 27 advances and retreats in the slider case 23. Has become.

Therefore, the flow rate meter 2 is sandwiched between the adapter units 21 and 22, and the slider case 23 is turned to screw the slider 26 so that the flow rate meter 2 is tightened. A flow rate meter unit A framed inside is constituted.

The meter unit A includes a storage box 3 composed of an upper box 31 having an opening / closing lid 33 on the upper surface and a lower box 32.
The outer diameter of the unit frame 1 is formed to fit between the upper box 31 and the lower box 32 in correspondence with the inner diameter of the storage box 3. The lower end thereof has a spacer projection 15, and the upper end thereof has a joining piece which is joined to a lower end fitting portion of the upper box 31 of the storage box 3.
Since the number 16 is formed, the meter unit A is tightly stored in the storage box 3 without rattling, and the storage operation can be easily performed.
