本考案はタンクローリ−の複数の底弁の閉鎖操作を１個
の操作レバーにより操作できるタンクローリ−における
緊急用閉鎖装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an emergency closing device for a tank lorry that can close a plurality of bottom valves of the tank lorry using a single operation lever.
タンクローリ−は、タンク本体を仕切板で仕切って複数
のタンク分室を設け、タンク本体の下部にタンク本体内
の液体の流通路を形成する配管を設けて、前記タンク分
室と前記配管との間にそれぞれ底弁を設けて、底弁の開
放によりタンク室内の液体を前記配管に導くように構成
されている。A tank lorry has a tank main body divided by a partition plate to have a plurality of tank compartments, and a lower part of the tank body is provided with piping that forms a flow path for liquid in the tank body, and a tank compartment is provided between the tank compartment and the piping. Each tank is provided with a bottom valve, and when the bottom valve is opened, the liquid in the tank chamber is guided to the piping.
また通常底弁は空気圧のオン・オフで開閉する空気圧操
作式が使用されている。In addition, the bottom valve is usually a pneumatically operated type that opens and closes by turning on and off air pressure.
従来のタンクローリ−における緊急閉鎖装置はたとえば
底弁操作弁と空気圧送源との配管の途中に１個の緊急弁
を設ける方式のものと、空気作動装置と底弁操作弁との
間の配管から分岐して緊急弁を設ける方式のものとがあ
った。Conventional emergency closing devices for tank trucks include, for example, one system in which one emergency valve is installed in the middle of the piping between the bottom valve operating valve and the air pressure supply source, and the other in the piping between the pneumatic operating device and the bottom valve operating valve. There was one that branched out and provided an emergency valve.
前者は、タンクローリ−においては、底弁操作弁の一方
はタンク上面にあって、その配管はタンク前面に沿って
設けられ、また空気圧送源はタンク前方に、緊急弁はタ
ンク後方に設ける必要があるため、全部の底弁操作弁に
空気を送るため大口径の配管をタンク前方から後方にま
で往復延設する必要があり、材料および取付工数に無駄
が多い欠点があった。For the former, in a tank truck, one of the bottom valve operation valves is located on the top of the tank, and its piping is installed along the front of the tank, and the pneumatic supply source must be installed at the front of the tank and the emergency valve at the rear of the tank. Therefore, in order to send air to all the bottom valve operating valves, it was necessary to extend large-diameter piping back and forth from the front of the tank to the rear, resulting in a large amount of waste in materials and installation man-hours.
また前者の方式は底弁操作弁に中立復帰式３ポジシヨン
の操作弁を用いることはできない欠点もあった。The former method also has the disadvantage that it is not possible to use a neutral return type three-position operating valve as the bottom valve operating valve.
後者は、複数の底弁を用いるタンクローリ−においては
、緊急弁を複数個必要とし、これらの運動操作が複雑と
なり、また大きな操作力を要するものであった。The latter requires a plurality of emergency valves in a tank truck that uses a plurality of bottom valves, which complicates the movement and operation of these valves and requires a large operating force.
本考案は上記にかんがみなされたもので、上記の欠点を
解消したタンクローリ−における緊急用閉鎖装置を提供
することを目的とする。The present invention has been conceived in view of the above, and its object is to provide an emergency closing device for a tank truck which eliminates the above-mentioned disadvantages.
以下、本考案を実施例により説明する。The present invention will be explained below with reference to examples.

is a bottom valve of each tank compartment, 5 is a bottom valve operating valve on the lower side of the tank, 6 is a bottom valve operating valve on the upper side of the tank, and 7 is attached to each bottom valve in order to operate the bottom valve 4 with air pressure. Cylinder part, 8 indicates the air pressure piping, 9 is a discharge valve, 1
0 is the emergency lever.
第２図は底弁操作弁を２ポジシヨンで何れの切替位置で

Reference numeral 4 denotes a fluid pressure notification device which is preferably attached to the circuit behind each operation valve and which senses the pressure in the circuit and notifies it with a display device such as a buzzer or lamp to notify the opening/closing of the bottom valve.
底弁操作弁５，６はＡポジションでは操作空気はシリン

向付勢時の態様が上記のＢポジションであり、作動体７
０の背後に空気圧が作用し、撥条に抗して作動体７０が
作動させられた態様が上記のＡポジションである。When the bottom valve operation valves 5 and 6 are in the A position, operating air is supplied to the circuit behind the cylinder section 7, and in the B position, the air in the circuit behind the cylinder section 7 is discharged to the outside. As shown schematically in the figure, the operating section is an operating body (which is biased in one direction by a plucked strip provided on the pilot operating section 27).
The actuating body 70 is configured in an integral relationship with the piston) 70, and the state in which it is biased in one direction is the above-mentioned B position, and the actuating body 7
The above-mentioned A position is the state in which air pressure acts behind 0 and the actuating body 70 is actuated against the plucked stripes.
また、底弁操作弁６のパイロット作動部２７の背後側回
路は緊急弁１７のａ、 ｂ、 ｃポートに接続する。Further, the rear circuit of the pilot actuating portion 27 of the bottom valve operating valve 6 is connected to ports a, b, and c of the emergency valve 17.
１０は緊急弁１７操作用ワイヤ１８に結合した緊急レバ

ジションに切替える。Now, when the bottom valve operating valve 5 is switched to the A position, air from the receiver tank 13 flows through the bottom valve operating valve 5 to the bottom valve cylinder section 7, and simultaneously flows to the pilot operating section 27 of the bottom valve operating valve 6. 4 is opened and the bottom valve operation valve 6 is switched to the A position.
従ってレシーバ−タンク１３からの空気は底弁操作弁６
を通して底弁操作弁５のパイロット操作部２７へ流れ、
底弁操作弁５，６はＡポジションに自己保持される。Therefore, the air from the receiver tank 13 is transferred to the bottom valve operating valve 6.
Flows through to the pilot operating portion 27 of the bottom valve operating valve 5,
The bottom valve operating valves 5 and 6 are self-held at the A position.
また底弁操作弁６をＡポジションに切替えたときの動作
も上記の場合と同様である。Further, the operation when the bottom valve operating valve 6 is switched to the A position is also the same as in the above case.
また底弁操作弁５をＢポジションに切替えると、底弁操
作弁６のパイロット操作部２７の空気は底弁操作弁５を

操作部２７をＢポジションに切替える。Furthermore, when the bottom valve operating valve 5 is switched to the B position, the air in the pilot operating part 27 of the bottom valve operating valve 6 is released to the atmosphere through the bottom valve operating valve 5, and the air in the bottom valve cylinder part 7 is released to the atmosphere. The bottom valve 4 is closed, and the pilot operating portion 27 of the bottom valve operating valve 6 is switched to the B position.
従って底弁操作弁５のパイロット操作部２７の空気は底
弁操作弁６を通って大気に放出され、底弁操作弁５，６

is self-held in the B position.

作弁５，６はＢポジションに切替る。When the emergency lever 10 is pulled or the fuse of the automatic shut-off device 19 melts while the bottom valve 4 is currently freely held in the above-mentioned A position, that is, the bottom valve 4 is open, the emergency valve 17 is switched. Ports a, b, and c of the emergency valve 17 are connected to the atmosphere;
The air in the cylinder part 7 of the bottom valve 4 and the air in the pilot operating parts 27 of the bottom valve operating valves 5 and 6 are released to the atmosphere through the emergency pipe connected to the bottom valve 4, the bottom valve 4 is closed, and the bottom valve operating valve 5 is closed. , 6 switches to the B position.
また、上記のＢポジションに自己保持されている状態に

遮断される。In addition, when the emergency lever 10 is returned to its original position while the bottom valve 4 is self-maintained at the B position, the emergency valve 17 is switched and the port a of the emergency valve 17 is switched. , communication between btC and the atmosphere is cut off.
従って底弁操作弁５または６をＡポジションに切替える
ことにより底弁４を開くことができる。Therefore, the bottom valve 4 can be opened by switching the bottom valve operating valve 5 or 6 to the A position.
従って、火災等の非常の際に底弁４の閉鎖操作を１個の
操作レバー１０により行なうことができる。Therefore, in the event of an emergency such as a fire, the bottom valve 4 can be closed using one operating lever 10.
また、タンク後方に設けた緊急弁１７には小口径の複数
の配管を片道設置すればよく、材料は少なくてすむとと
もに、設置による工数も少なくてすむ。In addition, it is sufficient to install a plurality of small-diameter pipes one way to the emergency valve 17 provided at the rear of the tank, which requires less materials and requires less man-hours for installation.
また底弁操作弁が２ポジシヨン、３ポジシヨンの場合に
も適用することができる。It can also be applied to cases where the bottom valve operating valve has two or three positions.
