欠点を有する。 Conventionally, for example, as shown in FIG. 1, a water governor B incorporating a diaphragm A operates a fuel supply amount adjustment valve C to a combustion heating device, and the operation of the water governor B is delayed to control the fuel supply. In order to slowly open the volume adjustment valve C, in a system in which a valve H is interposed in a branch water pipe G that connects the low pressure chamber D of the water governor B to the ventilary part F of the main water pipe E, the valve H is connected to a bulb. Adjust the distance K between valve I and valve seat J using screw L.
It is known that it can be adjusted freely (Report No. 5299 of 1983). By making the interval K of the valve H small at high water pressure and large at low water pressure, when the water governor B opens the regulating valve C, the water trapped in the low pressure chamber D is kept at the interval K. By keeping the amount of water that flows out through K constant, and by keeping the opening speed of the regulating valve C, which is linked to diaphragm A, constant and gentle, explosive fire transfer that occurs during high water pressure and low This is to prevent problems such as backfires and arrowheads that occur when water pressure is applied, but since the source water pressure applied to the water heater constantly fluctuates, the above-mentioned adjustment screw L can be used to adjust the distance K.
Those that adjust and fix the flames have the disadvantage that they cannot completely prevent problems such as explosive flame transfer, backfire, and arrow flames.

とを特徴とする。 The purpose of the present invention is to eliminate such drawbacks, and one of the two chambers partitioned by the diaphragm 1 is connected to the high pressure chamber 4 which is connected to the main water pipe 3 that supplies water to the heat exchanger 2, and the other is connected to the high pressure chamber 4 which is connected to the main water pipe 3 that supplies water to the heat exchanger 2. A water governor 8 configured in a low pressure chamber 7 communicating with a ventilary section 6 provided in the main water pipe 3 via a water pipe 5 operates a fuel supply amount regulating valve 10 to a combustion heating device 9. and a control device 1 for controlling the flow flowing out from the low pressure chamber 7 side into the branch water pipe 5.
1, the control device 11 is
The coil spring 12 is characterized by being composed of a coil spring 12 whose passage is a pitch interval, and a resistor 14 attached to the upstream end of the coil spring 12.

流量を調整できる様になつている。 In the control device 11 shown in FIG. 2, the resistor 14 constituting it is a ball. Note that 13 is a stopper for the resistor 14, and 16 is a stopper on the opposite side having a through hole 15. Reference numeral 17 denotes an adjustment pin which is screwed into the stopper member 16 so as to be able to adjust the minimum flow rate passing through the control device 11.

従来行われているものと特に変らない。 Next, the operation of this device will be explained. When opening the hot water tap valve 19, the pressure in the low pressure chamber 7 of the water governor 8 is changed to the high pressure chamber 4.
, the diaphragm 1 moves in the direction of opening the fuel supply amount regulating valve 10. Due to this movement, the water in the low pressure chamber 7 is pushed out to the branch water pipe 5 and flows out to the main water pipe 3 side via the control device 11. Therefore, the operation of the diaphragm 1 is slowed down, and a so-called slow ignition operation is performed in which the opening operation of the fuel supply amount adjustment valve 10 is slowed down. This operation is not particularly different from that performed conventionally.

に防止できる効果を有する。 In this device, the control device 11
is composed of a coil spring 12 with pitch intervals as passages and a resistor 14 attached to its upstream end, so the source water pressure is high and the diaphragm 1 of the water governor 8
When the operating speed of the control device 11 increases, the resistance of the flowing water to the resistor 14 increases and moves upward, and the pitch interval of the coil spring 12 narrows as shown in FIG. When the operating speed of the diaphragm 1 becomes slow due to low source water pressure, etc., the resistor 14 moves downward and the pitch interval of the coil spring 12 becomes wider as shown in the second figure, thereby controlling the control. The flow path resistance of the device 11 is reduced. For this reason,
In response to the constantly fluctuating source water pressure, the control device 11
By automatically adjusting the flow path resistance of the diaphragm 1, the operating speed of the diaphragm 1, that is, the flow rate of the water confined in the low pressure chamber 7 and flowing out into the branch water pipe 5 via the control device 11 is kept constant. The opening speed of the interlocked fuel supply regulating valve 10 can be kept constant at all times. Therefore, for the constantly fluctuating source water pressure,
It has the effect of completely preventing problems such as explosive fire transfer, backfire, and misfire.

の不具合を防止するものである。 The adjustment pin 17 is used to adjust the minimum flow rate at high water pressure depending on the gas type.
For high calorific value gas such as gas, the adjustment pin 1
7 upward, when the resistor 14 moves, the pitch interval of the coil spring 12 is narrowed as much as possible to reduce the amount of water passing through, and the opening speed of the fuel supply regulating valve 10 is made as slow as possible. In contrast, when using a gas with a low calorific value such as 6C, the adjustment pin 17 is lowered to reduce the amount of movement of the resistor 14 and the pitch interval of the coil spring 12 is reduced. By making the adjustment valve 10 wider than in the above case, the adjustment valve 10
This is to prevent problems such as backfire and misfire by making the valve opening speed faster than in the above case.

消できる効果を有する。 As explained above in detail, according to the present invention, the control device 11 interposed in the branch water pipe 5 is composed of a coil spring 12 whose path is the pitch interval and a resistor 14 attached to the upstream end of the coil spring 12. Therefore, with an extremely simple configuration, the pitch interval of the coil spring 12 is automatically adjusted in response to the constantly fluctuating source water pressure, and the amount of water flowing into the branch water pipe 5 via the control device 11 is always constant. The opening speed of the fuel supply amount regulating valve 10 interlocked with the diaphragm 1 can be kept constant at all times, which has the effect of eliminating the drawbacks seen in the conventional example.
