弁に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a flow rate regulating valve with a closing function used in water heaters, instantaneous water heaters for baths, etc., and gas appliances such as gas fan heaters.
従来の流量調整弁は流体圧調整機能を有する比例弁と閉
止機能を有する独立した電磁弁を直列に設けるのが通例
である。ここに言う比例弁とは流量調整弁の出口におけ
る流体圧を制御するものである。Conventional flow rate regulating valves typically include a proportional valve having a fluid pressure regulating function and an independent solenoid valve having a closing function in series. The proportional valve referred to here is one that controls the fluid pressure at the outlet of the flow rate regulating valve.
比例弁にあっては弁と弁座とが剛体で作られているため

。従って従来の流量調整弁では已むを得ず上記の比例弁
の他に閉止用として弁部に弾性部材（弁）と剛性部材〈
弁座）を組合せた電磁弁を使用する。In a proportional valve, since the valve and the valve seat are made of a rigid body, the airtightness during closing is insufficient and a sufficient closing function cannot be obtained. Therefore, in conventional flow rate regulating valves, in addition to the above-mentioned proportional valve, it is necessary to use an elastic member (valve) and a rigid member in the valve part for closing purposes.
Use a solenoid valve combined with a valve seat).

圧の変化に拘らず２次圧を常に一定に保つことである。When the fluid is city gas, one gas stop P1 is, for example, −
Although it changes depending on the time of day and therefore the 2nd revision P2 changes, the 2nd revision P2 of gas must be at a substantially constant pressure considering the gas appliances etc. to be used. That is, the purpose of the proportional valve is to always keep the secondary pressure constant regardless of changes in the primary pressure.

きに作用する。Fluid pressure (primary pressure) from the fluid supply source as shown in Figure 3
When PI is applied, the upward force and downward force applied to the proportional valve 47 cancel each other out because the effective areas of the diaphragm 44 and the proportional valve 47 are formed to be the same. Therefore, the proportional valve 47
By operating (pressing down) the fluid pressure at the outlet 32 through the proportional valve part is throttled to 2 revision P2, and if the above effective area is A, the proportional valve 47 has (P2 The pressing force of the proportional valve spring 46 acts upward on the proportional valve 47.

F=B・■・l (B: magnetic flux density, work: current, l: coil length) Due to this force F, from the above balance relationship, P2 pressure is a force F proportional to the current value supplied to the proportional valve drive section. The pressure is kept constant at a proportional set pressure.
従来の流量調整弁の電磁弁部と比例弁部は各々独立して
いたため、次のような欠点があった。Since the electromagnetic valve part and the proportional valve part of the conventional flow rate regulating valve were each independent, there were the following drawbacks.
イ、電磁弁部と比例弁部に各々の駆動装置が必要なため
、部品数が増えコスト高になる。B. Since the electromagnetic valve section and the proportional valve section require separate drive devices, the number of parts increases and costs increase.
口、電磁弁部と比例弁部が独立しているため取付けのス
ペースが必要となり、装置全体が大型となりまたこれら
の構成により流体の流路が複雑化され、通過抵抗が増え
る。Since the port, electromagnetic valve section, and proportional valve section are independent, installation space is required, and the entire device becomes large. Furthermore, these configurations complicate the fluid flow path and increase passage resistance.
ハ、弁駆動部が複数あるため消費電力が増える。C. Power consumption increases because there are multiple valve drive parts.
二、電磁弁部の駆動にプランジャ即ちソレノイド式を用
いるため、構造上動作が速動となり弁開時にプランジャ

的に燃える危険性がある。このため電流を流すソフト面
で級動作にするわずられしさがある。Second, since a plunger or solenoid type is used to drive the electromagnetic valve, the structure moves quickly, and when the valve is opened, the plunger 55 collides with the cushion 53, producing an impact sound. When used with gas, if installed in the final equipment, the gas will flow all at once, and the proportional valve will also open wide under initial conditions, so there is a risk of explosive combustion when ignited. For this reason, it is difficult to use the software that allows current to flow in class operation.

However, by changing the current value etc., it is operated in class operation.

流量調整弁によって達成される。According to the present invention, the above problem can be solved by using a yoke, a permanent magnet,
A cylindrical bobbin that is loosely fitted into the body of the yoke and has a coil wound on the outside, and an adjustment screw that is adjustable and pushed down on a pan provided at the bottom of the cylindrical bobbin via an adjustment spring. In a flow rate regulating valve comprising a valve drive unit, a diaphragm fixed to a proportional valve shaft at the lower part of the pan, and a proportional valve, the proportional valve shaft is separated from the pan, and the proportional valve shaft is moved in the axial direction of the proportional valve shaft. A connecting rod is inserted into the formed through hole, the upper end of the connecting rod is fixed to the pan, and a shutoff valve made of an elastic material is fixed to the lower end of the connecting rod. A diaphragm is disposed below the proportional valve to seal the clearance between the proportional valve and the connecting rod, and a predetermined gap is provided in the axial direction between the pan and the proportional valve shaft. This is achieved by a flow regulating valve with a closing function.

A through hole in the axial direction is formed at 47>.

この連接棒１の上端をパン３８に固着しまた連接棒１の
下端に弾性材料からなる閉止弁２を固設する。The upper end of the connecting rod 1 is fixed to a pan 38, and the shutoff valve 2 made of an elastic material is fixed to the lower end of the connecting rod 1.
閉止弁２は流路に設けた閉止弁座３に上向きに着座する
ように形成され、流量調整弁本体の底部４と閉止弁２間
に閉止弁スプリング５を配設する。The shutoff valve 2 is formed to sit upward on a shutoff valve seat 3 provided in the flow path, and a shutoff valve spring 5 is disposed between the bottom portion 4 of the flow regulating valve body and the shutoff valve 2.

積は閉止弁２の有効面積に略等しく設定されている。A second diaphragm 7 is fitted into a recess provided on the lower surface of the proportional valve 47 via a diaphragm retainer 6 made of an elastic body. The center hole of this second diaphragm 7 is in close contact with the outer periphery of the connecting rod 1 to keep it airtight. Further, the effective area of the second diaphragm 7 is set to be approximately equal to the effective area of the shutoff valve 2.

A gap A is provided.

In this case, initially, as the connecting rod 1 descends, the shutoff valve 2 fixed thereto opens, and when the connecting rod 1 further descends and the pan 38 comes into contact with the upper part of the proportional valve shaft 48, the proportional valve 47 opens. Thereafter, proportional control is performed by changing the current value flowing through the proportional valve drive section.

However, it is also possible to use an electromagnetic repulsion type in which the same poles of a movable permanent magnet and an electromagnet face each other to utilize repulsive force, or an electromagnetic repulsion type in which a movable plunger is placed in a coil. It is also possible to use a plunger type that obtains the thrust of a plunger.

いので作動が緩動となる等の利点がある。The present invention is constructed as described above, eliminates the solenoid valve that was present in conventional devices, and configures the proportional valve part and the shutoff valve part by one proportional valve drive part, so the number of parts is small and the price is low. Since the installation space is small and the flow path is simple, the resistance to fluid passage is reduced and power consumption is also reduced. Further, since the valve portion is opened in two stages and a solenoid type is not used, there are advantages such as slow operation.
