| 摘要 |
The standpipe hydraulic float valve of the present invention employs a mechanical linkage between the float mechanism, which is responsive to changes in the fluid level in the standpipe, and a pilot valve, which regulates a control valve that controls the flow of fluid into the standpipe through its inlet port. Therefore, the mechanical linkage actuates the pilot valve in response to changes in the fluid level in the standpipe so as to provide a substantially continuously variably controlled fluid supply flow into the standpipe housing and thereby maintain a substantially constant fluid level in the standpipe housing so as to maintain a substantially continuous flow pressure into the fluid flow system to which the standpipe hydraulic float valve is connected.
