    • PURPOSE:To offer a fluid flow control valve to be used in a water governor etc. of a home-use gas boiler etc. which does not require use of any diaphragm by such a construction that a pressure correction valve consolidated with the control valve is furnished on the high pressure side of the inflowing side of rate- of-flow control part in order to separate the high pressure part from the low pressure part and to hold the rate of flow always constant. CONSTITUTION:By means of a control valve 3 including a pressure correction valve 2, the water governor 1 forms a high pressure chamber 5 for water inlet 4 and an intermediate pressure chamber 7 to which the pressure is reduced by the control valve 3 and water body control part 6. A resistant orifice 8 is furnished on the outflowing side of the control valve 3, to form a low pressure chamber 9 for flowing-out to the water outlet 10. The pressure in this low pressure chamber 9 is led to the bottom of the pressure correction valve 2 through a conduit pipe 11; that is to say, the pressure correction valve 2 separate the high pressure chamber 5 from low pressure chamber 9. A spring 13 is provided for the purpose of hold the control valve 3 open always to the water body control part 6. Accordingly, there is no need to use any diaphragm.
    • 目的:提供一种用于家用燃气锅炉等的调压器等的流体流量控制阀,其不需要使用通过与控制阀固定的压力校正阀的结构来使用任何隔膜 设置在流量控制部分的流入侧的高压侧,以将高压部分与低压部分分离并保持流量始终恒定。 构成:通过包括压力校正阀2的控制阀3,水调节器1形成用于进水口4的高压室5和通过控制阀3减压的中间压力室7和水体 在控制阀3的流出侧设置有阻力孔8,以形成用于流出到出水口10的低压室9.该低压室9中的压力被引导到底部 的压力校正阀2通过导管11; 也就是说,压力校正阀2将高压室5与低压室9分开。设置弹簧13用于将控制阀3始终保持在水体控制部6上。因此,存在 无需使用任何隔膜。
