産業上の利用分野
本考案はガス瞬間湯沸器の出湯湯温制御に用いられるガ
ス比例制御弁に関するもので、特に、電流値に比例して
ガスの供給量を比例的に制御するガス比例制御弁のガス
変換を容易ならしめる構造に関するものである。[Detailed description of the invention] Industrial field of application The invention relates to a gas proportional control valve used to control the temperature of hot water discharged from a gas instantaneous water heater. This invention relates to a structure that facilitates gas conversion of a proportional gas control valve.
従来例の構成とその問題点
従来のこの種のガス比例制御弁を用いたガス瞬間湯沸器
の要部構成図を第３図に示す。Construction of a conventional example and its problems FIG. 3 shows a construction diagram of the main parts of a conventional gas instantaneous water heater using this type of gas proportional control valve.
図において、熱交換器２２を加熱するメインバーナ２３
にガス供給を行なうガス配管２４には、ガスガバナＧ２
５及びガス比例制御弁２６が接続されている。In the figure, a main burner 23 that heats a heat exchanger 22
A gas governor G2 is connected to the gas pipe 24 that supplies gas to the
5 and a gas proportional control valve 26 are connected.
ガスガバナＧ２５は供給ガス圧をそれぞれのガス種に適
応した一定のガス圧に調圧する。The gas governor G25 regulates the supply gas pressure to a constant gas pressure adapted to each gas type.
また、ガス比例制御弁２６は、熱交換器２２の出口湯温
を検知する湯温検知センサ２７の出力信号と、温度設定
部２８で設定された設定湯温とを比較器２９で比較し、
この比較器２９からの出力信号によりコイル３０に電流
が供給されて、ガス比例制御弁２６を流れるガス量を比
例制御するものである。In addition, the gas proportional control valve 26 compares the output signal of the hot water temperature detection sensor 27 that detects the outlet hot water temperature of the heat exchanger 22 with the set hot water temperature set by the temperature setting section 28 using a comparator 29,
A current is supplied to the coil 30 based on the output signal from the comparator 29, and the amount of gas flowing through the gas proportional control valve 26 is proportionally controlled.
このガス比例制御弁２６の動作をさらに詳しく説明する
と、コイル３０に電流が流れていない時には板バネ３１
は常に弁体３２を弁座体の弁座３３に押圧すると同時に
、プランジャ３４が左右に振れてボビン３５に接するの
を防止する。To explain the operation of the gas proportional control valve 26 in more detail, when no current flows through the coil 30, the leaf spring 31
always presses the valve body 32 against the valve seat 33 of the valve seat body, and at the same time prevents the plunger 34 from swinging left and right and coming into contact with the bobbin 35.
コイル３０に電流が流れると、電磁力が発生してプラン
ジャ３４を上に引き上げる力が働く。When current flows through the coil 30, an electromagnetic force is generated and a force that pulls the plunger 34 upward is exerted.
この力が板バネ３１の力に打ち勝つとプランジャ３４は
引き上げられて弁体３２が弁座３３から離れ、電磁力と
板バネ３１め力がつり合った所で静止する。When this force overcomes the force of the leaf spring 31, the plunger 34 is pulled up, the valve body 32 separates from the valve seat 33, and comes to rest at a place where the electromagnetic force and the force of the leaf spring 31 are balanced.
弁体３２の開度はコイル３０に流れる電流に比例する。The opening degree of the valve body 32 is proportional to the current flowing through the coil 30.
この特性を利用して瞬間湯沸器の出湯温度を比例制御す
るものである。This characteristic is used to proportionally control the hot water temperature of the instantaneous water heater.
ところで、ガス器具にはガス変換ということが生ずる。By the way, gas conversion occurs in gas appliances.
具体的には都市ガス（ガス種：４Ａ、４Ｂ、４Ｃ，５Ａ
Ｎ、５Ａ、５Ｂ、５Ｃ，６Ａ、６Ｂ、６Ｃ，７Ｃ）地域
からプロパンガス（ＬＰＧ）地域へ引越した場合、又は
都市ガスから天然ガス（ガス種：１３Ａ、１２Ａ。Specifically, city gas (gas types: 4A, 4B, 4C, 5A
N, 5A, 5B, 5C, 6A, 6B, 6C, 7C) area to a propane gas (LPG) area, or from city gas to natural gas (gas type: 13A, 12A).
１１Ａ）へガス転換する場合などである。11A), etc.
例えば、都市ガス６Ｃから天然ガス１３Ａに転換した場
合、ガス圧（ｍｍＡｇ）で約２倍、カロリー（Ｋｃａｌ
／ｈ）で約２倍高くなるので、転換前の６Ｃ仕様のまま

路のゲインを変えない限り同じコイル電流値■の変化量
△■に対して供給発熱量Ｐの変化量△ＰＢ（△ＰＢ〉△
ＰＡ）が過大になるため設定した湯温に安定するまでの
時間が長い。For example, when converting from city gas 6C to natural gas 13A, the gas pressure (mmAg) is approximately doubled, and the calorie (Kcal) is
/h), so if the 6C specification before conversion is maintained, as shown in Figure 4, with 13A gas, the amount of change in the coil current value ■ will be the same unless the gain of the control circuit is changed △ The amount of change in the supplied calorific value P with respect to ■ △PB (△PB〉△
PA) becomes excessive, so it takes a long time for the water temperature to stabilize at the set temperature.
さらに、同図に示すように、都市ガス６Ｃからプロパン
ガスＬＰＧに変換した場合にはＬＰＧはガス圧で約５倍
、カロリーで約４倍となり、殆ど比例域がとれず、一般
のオン、オフ弁の動作に近似し、比例弁としての機能を
全く果さない。Furthermore, as shown in the same figure, when converting from city gas 6C to propane gas LPG, the gas pressure of LPG is about 5 times, and the calorie is about 4 times, so there is almost no proportional range, and it is not possible to use normal on/off. It approximates the operation of a valve and does not function as a proportional valve at all.
このようなガス転換時の問題を解決する手段として、従
来より実施されてきたものは、ガス転換が生ずるごとに
、弁座３３を有する弁座体３６そのものを転換された力
゛ス種に適応したものに取替えることであった。As a means to solve such problems at the time of gas conversion, what has been conventionally implemented is to adapt the valve seat body 36 having the valve seat 33 to the type of gas converted every time gas conversion occurs. The idea was to replace it with one that had been replaced.
具体的には、弁座３３を流れるガス流量を適正な供給発
熱量が得られる流量まで絞るために弁座３３の内径を小
さくする。Specifically, the inner diameter of the valve seat 33 is made small in order to throttle the gas flow rate flowing through the valve seat 33 to a flow rate at which an appropriate amount of supplied heat is obtained.
さらに力゛ス圧力の増大によって、ダイヤフラム３７が
持ち上げられるために、弁体３２の全閉時の閉め切り圧
が弱くなり、閉め切りが不完全になるため、弁座３３の
高さを弁体３２１則へ、より高くする。Furthermore, as the diaphragm 37 is lifted due to the increase in force pressure, the closing pressure when the valve body 32 is fully closed becomes weaker, and the closing becomes incomplete. To, make it higher.
これらの条件をみたす新しい弁座体（副弁座体）に取替
えていた。It was replaced with a new valve seat body (auxiliary valve seat body) that met these conditions.
しかしこの弁座体３６の取替え作業は、小さい部品であ

能悪化につながるため熟練を要するものでもあった。However, since this work of replacing the valve seat body 36 involves replacing the valve seat body 36, which is a small part, if it remains attached to the valve body or inside the appliance, other water piping, electrical wiring, and various parts may become obstacles. Because of the difficulty, we first removed the valve body from the case piping 24.2 The electromagnetic coil unit was removed and the valve seat body 36 was replaced, which was an extremely time-consuming and inefficient task, and also caused large assembly errors. It also required skill because it led to performance deterioration.
さらにガス種毎に取替え部品を保管するパーツ管理コス
トも無視できないものであった。Furthermore, the parts management cost of storing replacement parts for each gas type could not be ignored.

である。Technical problem of the invention The technical problem of the invention is that by operating the sub-valve seat body having a sub-valve seat corresponding to the converted gas type from the outside of the valve body, the main valve seat body originally used To enable the sub-valve seat to be set in place of the main valve seat.

ことである。Technical means of the invention The technical measures taken to solve the above technical problems are: ■ A recess (guide tube) in the bottom of the valve body on the central axis of the main valve seat.
A sub-valve seat body is provided which fits into the recess so as to move forward and backward and has an operating portion protruding from the bottom of the recess, and the upper end of the sub-valve seat body is provided with a through hole in the side surface. a cylindrical portion with a bottom is provided to form a gas passage; (1) an annular flange portion is formed in the upper part of the through hole to seal the main valve seat via a seal backing; (2) the annular flange portion is The height is such that the upper end of the auxiliary valve seat projects upwardly than the upper end of the main valve seat when in contact with the main valve seat, and (1) means for fixing the auxiliary valve seat body is provided in the recess. .
技術的手段の作用 上記技術的手段の作用は次のとおりである。Action of technical means The effects of the above technical means are as follows.
すなわち、通常は弁体１０によって主弁座５の開口度が
通電量に比例して可変し、ガス流量が比例制御される。That is, normally, the degree of opening of the main valve seat 5 is varied by the valve body 10 in proportion to the amount of energization, and the gas flow rate is controlled proportionally.
ガス変換時に、副弁座体の操作部を外部より、操作して
環状フランジ部のシールバッキングが主弁座に当接する
まで挿入すると、副弁座の上端が主弁座よりも弁体１０
側に突出した状態（副弁座が主弁座よりも高い位置）で
個定される。During gas conversion, when the operating part of the sub-valve seat body is operated from the outside and inserted until the seal backing of the annular flange part contacts the main valve seat, the upper end of the sub-valve seat is closer to the valve body 10 than the main valve seat.
It is identified in a state where it protrudes to the side (the sub-valve seat is at a higher position than the main valve seat).
このとき環状フランジ部は主弁部の下流側の開口を密閉
してしまうのでガス流路は副弁座体の有底円筒部に限定
される。At this time, the annular flange portion seals the downstream opening of the main valve portion, so the gas flow path is limited to the bottomed cylindrical portion of the sub-valve seat body.
したがって副弁座体のセット後は弁体１０により可変さ
れる副弁座の開口度によってガス流量が決定されること
となり、通電量に比例してこの開口度が可変されること
から、ガス流量が比例的に制御される。Therefore, after the sub-valve seat body is set, the gas flow rate is determined by the opening degree of the sub-valve seat, which is varied by the valve body 10. Since this opening degree is varied in proportion to the amount of energization, the gas flow rate is is proportionally controlled.
また、通電量が零のときの副弁座の閉め切りも副弁座が
弁体側に突出した位置で弁体１０に当接することから弁
体１０を付勢するスプリングの付勢力が大きくなり確実
に行なわれる。In addition, when the auxiliary valve seat is closed when the amount of current is zero, the auxiliary valve seat comes into contact with the valve body 10 at a position protruding toward the valve body, so the biasing force of the spring that biases the valve body 10 becomes large, and the closing is ensured. It is done.
したがって変換後においても変換前の比例制御弁の機能
を充分保持することができる。Therefore, even after conversion, the function of the proportional control valve before conversion can be sufficiently maintained.
考案の特有の効果
副弁座体がフランジ及びその上面のシールバッキングを
有するために、このシールバッキングのしめ代相当の範
囲内で、副弁座の高さの微調整を外部から行うことがで
きる。Unique effects of the invention: Because the sub-valve seat body has a flange and a seal backing on its upper surface, the height of the sub-valve seat can be finely adjusted from the outside within a range equivalent to the tightening allowance of this seal backing. .
