進口流量控制閥產(chǎn)品詳情 Product details

流量控制閥主要安裝在配水管路需要控制流量的管路中，將上游的高壓降為低壓，保持預(yù)定的流量不變，將過大流量限制在一個預(yù)定值，即使上游的壓力變化，也不影響主閥下游的流量，利用管路中的水壓自動操作主閥瓣的上下移動，控制閥口開度，主閥安裝在送配水管路控制流量的管線中。可先設(shè)定調(diào)正閥門上部向?qū)д{(diào)節(jié)閥及導(dǎo)閥某一固定流量，就可使通過主閥的流量保持不變，即使主閥上游的壓力發(fā)生變化，也不會影響?？傊摦a(chǎn)品是生活給水、消防系統(tǒng)及工業(yè)給水系統(tǒng)的理想產(chǎn)品The flow control valve is mainly installed in the pipeline where the flow needs to be controlled in the water distribution pipeline. It reduces the upstream high pressure to low pressure, maintains the predetermined flow rate, and limits excessive flow to a predetermined value. Even if the upstream pressure changes, it does not affect the flow downstream of the main valve. The water pressure in the pipeline automatically operates the up and down movement of the main valve disc to control the valve opening. The main valve is installed in the pipeline where the flow is controlled in the water supply and distribution pipeline. You can first set a fixed flow rate for the upper guide regulating valve and guide valve of the adjustment valve to maintain the flow rate through the main valve unchanged, even if the pressure upstream of the main valve changes, it will not affect it. In short, this product is an ideal product for domestic water supply, fire protection systems, and industrial water supply systems

進口流量控制閥工作原理 Working principle

當(dāng)閥門從進口端給水時，水流過針閥進入主閥控制室，并經(jīng)過導(dǎo)閥、球閥流出主閥控制室到出口，此時主閥處于全開或浮動狀態(tài)。調(diào)定主閥上部的流量調(diào)節(jié)閥，可為主閥設(shè)定一定開度。調(diào)節(jié)針閥開度和調(diào)節(jié)導(dǎo)閥彈簧壓力，即可使主閥開度保持在設(shè)定開度，并在壓力變化時導(dǎo)閥進行自動調(diào)節(jié)，保持流量不變。
