Description

【考案の詳細な説明】 [考案の目的] (産業上の利用分野) この考案は、ガスメータの給排気構造に関する。 Description of the invention] [devised purpose of] (relates) This invention relates to an air supply and exhaust structure of the gas meter.

(従来の技術) ガスメータの給排気口は、周知のようにのう膜によって内側計量室と仕切られた外側計量室と、この外側計量室のための分配室とを連通するために形成されるのであるが、この給排気口の周りを密封してガスが内側計量室に洩れるのを防止する必要がある。 Supply and exhaust port (prior art) the gas meter is formed for communicating with an outer metering chamber partitioned with the inner measuring chamber by known as sac membrane, and a distribution chamber for the outer metering chamber Although the it is necessary to prevent gas and sealed around the air supply and exhaust port from leaking inside the metering chamber.

この給排気口の構造としては、従来第3図(a)に示すようにボディAの内部に周縁のリム1aを固定するのう膜1の外周の一部にボディAに開口した給排気口2の周縁に装着されるパッキング3を一体に形成するか、あるいは第3図(b)に示すように前記のう膜とは独立した給排気口パッキング4を給排気口2の周縁に固定するかのいずれかの構造が取られている。 The structure of the paper outlet, supply and exhaust port which opens into the body A part of the outer periphery of the sac membrane 1 for fixing the rim 1a of the periphery in the interior of the body A as shown in prior art FIG. 3 (a) packing 3 to be attached to the second peripheral edge or integrally formed, or the the sac membrane as shown in FIG. 3 (b) to fix separate the supply and exhaust vent packing 4 to the periphery of the air supply and exhaust port 2 Kano any of the structure have been taken.

また、この給排気口2とのう膜1の周縁の間ものう膜1 Further, the film 1 No even while the periphery of the supply and exhaust port 2 with the sac membrane 1
によって仕切られる二つの計量室の間のシールのためにのう膜ブリッジが必要である。 Sac membrane bridge for sealing between the two weighing chambers partitioned by is required.

このため、従来では第3図(c)に示すようにのう膜1 Therefore, in the conventional sac as shown in FIG. 3 (c) film 1
及び給排気口2が連続した形状の突出部5aを有する腹板5の裏面側において、給排気口2とのう膜1の境界部分に沿って予めのう膜ブリッジ6の両端を接着固定しておき、腹板5をボディAに固定した状態で前記のう膜ブリッジ6が境界部分に挟着され、これによって各計量室間がシールされる構造となる。 And the back surface side of the webs 5 of the supply and exhaust port 2 has a protruding portion 5a of the continuous shape, both ends of the bonded pre-sac film bridge 6 along the boundary of the supply and exhaust port 2 with the sac membrane 1 and advance, are clamped to webs 5 on the sac membrane bridge 6 boundary portion while being fixed to the body a, a structure in which a result between the metering chamber is sealed.

(考案が解決しようとする課題) しかしながらこの構造では、腹板5の裏面にのう膜ブリッジ6を接着する構造なので、作業性が悪く、また位置不良などによるシール不良,内部洩れ等が生ずる場合があるほか、組立時におけるのう膜ブリッジ6の落下や、 If (problem devised to be Solved) However in this construction, since the structure for adhering the sac film bridge 6 on the rear surface of the webs 5, poor workability, and the sealing failure caused by misregistration, the internal leakage or the like occurs in addition to there, drop or of the sac membrane bridge 6 at the time of assembly,
接着忘れなども生ずる惧れがあり、いずれも歩留まり低下要因となっていた。 It is a possibility also arise such as an adhesive forget there is, both has been a decrease in yield factor.

そこでこの考案は、腹板に対してのう膜ブリッジを接着することなくのう膜ブリッジを給排気口とのう膜周縁との境界部に配置できるようにしたガスメータの給排気口構造を提供することを目的とする。 Therefore this invention is provide a supply and exhaust port structure of the gas meter which is to be arranged in the boundary portion between the Hare film peripheral edge of the No film bridge supply and exhaust port without bonding the sac membrane bridge against web plate an object of the present invention is to.

(課題を解決するための手段) 前記目的を達成するため、この考案は、ガスメータのボディに設けたのう膜によって内側計量室と仕切られた外側計量室と、この外側計量室のための分配室とを連通する給排気口の周縁に独立した形状の給排気口パッキングを配置するとともに、この給排気口パッキングには、これに隣接して配置されるのう膜の外周縁部上面に向けて円弧状ののう膜ブリッジを一体に延設し、ボディの開口面に固定される腹板によって前記のう膜ブリッジを締付け固定し、前記各計量室間を気密にシールすることを特徴とするものである。 To achieve (solutions for the problem) the object, this invention comprises an outer metering chamber partitioned with the inner measuring chamber by caries film provided on the body of the gas meter, the distribution for the outer metering chamber chamber and with arranging the supply and exhaust vent packing periphery in a separate form of supply and exhaust port communicating with the, this supply and exhaust port packing, toward the outer edge the upper surface of the sac membrane disposed adjacent thereto and characterized in that the arc-shaped sac membrane bridged integrally extended, the sac membrane bridge fastened and fixed by webs fixed to the opening surface of the body to seal airtightly between the respective metering chambers Te it is intended to.

また、この考案では、のう膜の周縁部に前記給排気口パッキングの円弧部に向けてのう膜ブリッジを一体に延設することもできる。 Further, in this invention, the sac membrane bridge toward the arcuate portion of the supply and exhaust port packing the periphery of the sac membrane may be integrally extended.

(作用) 以上の構成によれば、のう膜をボディに固定し、次いで、前記給排気口パッキングを給排気口の周縁に固定すれば、必然的にこれと一体化されたのう膜ブリッジがのう膜の周縁に精度良く重なり、次いで腹板をボディに固定することで、のう膜ブリッジは腹板ののう膜周縁との間に挟着され、給排気口と計量室間をシールする。 According to the configuration described above (action), the sac membrane is fixed to the body, then, be fixed to the supply outlet packing the periphery of the intake and exhaust ports, sac membrane bridges necessarily integrated with this precisely overlap the periphery of Gano film, followed by fixing the belly plate to the body, caries film bridge is sandwiched between the sac membrane periphery of webs, between weighing chamber and the supply and exhaust port to seal.

また、請求項2では前記とは逆の取付け手順とすることで同様にのう膜ブリッジが境界部分に精度良く重なることになる。 The inverse of similarly sac membrane bridge by the mounting procedure so that the overlap precisely in the boundary portion between the in claim 2.

(実施例) 以下、この考案の一実施例を図面を用いて詳細に説明する。 (Example) Hereinafter, will be described in detail with reference to the drawings an embodiment of this invention. なお、従来と同一箇所には同一符号を付し、異なる部分のみ異なる符号を用いて説明する。 The same reference numerals are assigned to the conventional same position is described with reference to only the different portions different signs.

第1図は(a),(b)はこの考案による給排気口パッキング10を示し、第2図は同パッキング10を用いた組立状態を示すものである。 Figure 1 is (a), (b) shows the supply and exhaust vent packing 10 according to the invention, FIG. 2 shows the assembled state with the packing 10.

図における給排気口パッキング10は、のう膜1とは別個のゴム状成形体であって、給排気口2の形状に沿って内側が円弧状に湾曲した楕円径に形成されている。 Supply and exhaust vent packing 10 in figure, the sac membrane 1 be a separate rubber-like molded body, inward along the shape of the air supply and exhaust port 2 is formed in an elliptical diameter curved in an arc shape.

この給排気口パッキング10の湾曲部10aの上部にはこれと同様の円弧状をなし、かつ断面が逆L字形をなしてのう膜1の周縁のリム1aに重なるのう膜ブリッジ12がオーバハング状に一体成形されている。 The supply and exhaust port packing at the top of the curved portion 10a of 10 without a similar arc-shaped and which, and caries film bridge 12 which overlaps the rim 1a of the cross section of the sac membrane 1 forms an inverted L-shaped peripheral edge overhang It is integrally molded to Jo.

以上の構成において、まずのう膜1の周縁部をボディA In the above configuration, the first peripheral portion of the sac membrane 1 Body A
に固定し、次いで給排気口パッキング10を給排気口2の周縁に固着すれば、前記のう膜ブリッジ12は前記のう膜1の周縁リム1aの上部にこれの円弧に沿って精度良く重なることになる。 Fixed to, and then be secured to the supply and exhaust port packing 10 on the periphery of the air supply and exhaust port 2, the sac film bridge 12 overlaps precisely along an arc of this on top of the peripheral rim 1a of the sac membrane 1 It will be.

したがって、この状態で前記腹板5をボディAに接着すれば、前記のう膜ブリッジ12はこの腹板6とボディA間に挟着され、計量室間のシールを行うことになる。 Therefore, when bonding the webs 5 in this state to the body A, the sac film bridge 12 is sandwiched between the webs 6 and the body A, so that for sealing between the metering chamber.

なお、第3図(a)に示すパッキング一体形ののう膜の場合には、前記のう膜ブリッジがオーバハング形状であることや、他の部分に比べて加硫が進みにくいため、この考案は適用されない。 In the case of FIG. 3 (a) to show packing integral of caries film is and, since the vulcanization difficult travels than other portions the caries film bridge is overhung shape, this invention It does not apply.

しかし、実施例とは逆にのう膜1の外周リム部1aにのう膜ブリッジ12を一体に形成することも前述の不利な条件を除けば可能であり、この場合の取付け手順は、前記とは逆に給排気口パッキング10を先にボディAに固定し、 However, to form a sac film bridge 12 to the outer peripheral rim portion 1a of the sac membrane 1 contrary to the embodiment integrally are possible except for adverse conditions mentioned above, the mounting procedure in this case, the fixed to the body a before the supply and exhaust vent packing 10 Conversely,
次いでのう膜1を固定すれば良い。 Then it may be fixed to sac membrane 1.

(考案の効果) 以上実施例によって詳細に説明したように、この考案によるガスメータの給排気口構造にあっては、従来に比べてのう膜ブリッジの腹板に対する接着作業が省略でき、 As explained (Effect of invention) above examples detail, in the supply and exhaust port structure of the gas meter according to the invention, it can be omitted bonding work for webs of sac membrane bridge compared with the conventional,
組立の簡素化を図ることができ、のう膜ブリッジの位置精度が向上するほか、脱落や接着忘れなどのミスによる歩留まり低下を未然に防止できる。 It is possible to simplify the assembly, in addition to improving the positional accuracy of the sac membrane bridge prevents yield reduction due to errors such as dropping or adhesive forgotten in advance.
