る。FIG. 4 shows an example of the constant flow rate means 21. Flanges 22, 22 are provided in the middle of the liquid pipe 3, and the flanges 2 are attached to both ends of the metal flexible pipe 22.
The orifice 2 is formed by the flanges 3 and 23 and the flanges 22 and 22.
4 are joined with a flange packing 25 interposed therebetween. An orifice 24 is set to an arbitrary constant flow rate by suppressing a sudden large outflow of the LPG liquid by the hole diameter of the orifice 24. Also,
Instead of the orifice 24 with the flange packing 25,
As shown in FIG. 4 (c), a constant flow valve 27 capable of arbitrarily setting the degree of opening of the opening 27a may be connected between the flanges 22, 22, so that the amount of LPG passing through the liquid pipe 3 is kept constant. The configuration of the constant flow rate means 21 is not limited as long as the means is set as described above. The opening degree of the opening 27 a of the constant flow valve 27 is determined according to the amount of fluctuation of the load 15 and the operating flow rate of the overflow prevention valve 2, and is narrower than the hole diameter of the liquid pipe 3.

困難となる。The constant flow rate means 21 is connected to the LPG in the bulk storage tank 1.
The reason why the LPG liquid is provided at a position lower than the liquid level is that the LPG liquid passing through the constant flow rate means 21 is in a complete liquid state and the flow rate can be kept constant. If the constant flow rate means 21 is above the LPG liquid level, the LPG passing through the constant flow rate means 21 may be in a gas-liquid mixed state, making it difficult to keep the flow rate constant.

不具合が解消される。As described above, by providing the constant flow rate means 21 for keeping the amount of liquid passing through the liquid pipe 3 constant, the load 15 is ignited, the gas pressure decreases, and the vaporizer 4
The pressure at the outlet of the valve drops, and the liquid amount control valve 6 opens greatly (FIG. 5).
(C), the flow rate of the LPG solution tends to flow excessively, and is limited by the constant flow rate means 21 so that the flow rate does not exceed the operating flow rate value of the overflow prevention valve 2. Since the outflow of the LPG liquid is not stopped at every 15 ignitions, the problem of LPG supply by the bulk system is eliminated.

Since the flow rate means is provided, even if a large amount of LPG liquid flows due to a load change, the flow rate is limited by the constant flow rate means, and a constant amount of LPG liquid always flows, so that LPG can be supplied by a stable bulk system.
