一、進(jìn)口泄壓持壓閥產(chǎn)品詳情

進(jìn)口泄壓持壓閥主要用于消防或其他供水系統(tǒng)中，屬于消防水力控制閥，以防止系統(tǒng)超壓或維持消防供水系統(tǒng)的壓力。消防泵關(guān)閉后還可以特性，使比重較大、直徑較大的懸浮顆粒不會(huì)進(jìn)入控制系統(tǒng)，確保系統(tǒng)循環(huán)暢通無(wú)阻，使閥門能安全可靠地運(yùn)行。

二、進(jìn)口泄壓持壓閥技術(shù)參數(shù)

三、進(jìn)口泄壓持壓閥工作原理

可將給水管中超過(guò)引導(dǎo)閥安全設(shè)定值之壓力釋放，并維持管中壓力于一安全設(shè)定值以下，以防止管中高壓或突壓(SURGE)毀損管線或設(shè)備。可用于高層大樓消防測(cè)試循環(huán)系統(tǒng)之泄壓用，以防止水壓過(guò)高造成系統(tǒng)危險(xiǎn)。持壓閥：可維持主閥上游供水壓力于某一設(shè)定值以上，以保障主閥上游供水區(qū)之壓力。

四、進(jìn)口泄壓持壓閥性能特點(diǎn)

1、采用全通徑流線型設(shè)計(jì)，流體阻力小，流量大，抗氣蝕能力強(qiáng);

2、密封圈采用國(guó)際先進(jìn)的星型密封圈結(jié)構(gòu)，不脫落，不翹起，彈性密封。由一個(gè)具有低摩擦、定位精準(zhǔn)的閥桿導(dǎo)向，使密封性能可靠，壽命更長(zhǎng);

3、可拆卸不銹鋼304閥座，耐腐蝕，耐沖刷，密封性能好;

4、閥體采用高強(qiáng)度球墨鑄鐵精密鑄造，內(nèi)外噴涂無(wú)毒環(huán)氧樹脂;

5、膜片由尼龍?jiān)鰪?qiáng)橡膠制造，立體網(wǎng)紋、彈性好、耐壓高，使用壽命長(zhǎng)久;

6、系列產(chǎn)品采用不銹鋼外管路，耐腐蝕，強(qiáng)度更高。

1、 Details of imported pressure relief valve

The imported pressure relief and pressure holding valve is mainly used in fire fighting or other water supply systems. It belongs to fire hydraulic control valve to prevent system overpressure or maintain the pressure of fire water supply system. After the fire pump is shut down, it can also make the suspended particles with larger proportion and larger diameter not enter the control system, ensure the smooth circulation of the system, and make the valve operate safely and reliably.

2、 Technical parameters of inlet pressure relief valve

Nominal diameter: dn50-dn500 valve body material: ductile iron, cast steel, stainless steel, copper

Nominal pressure: 1.0mpa-2.5mpa valve cover material: ductile iron, cast steel, stainless steel, copper

Applicable temperature: 0 ℃ - 95 ℃. Spring material: stainless steel 304

Connection mode: flange connection; diaphragm material: EPDM

Applicable medium: water, non corrosive liquid guide valve accessories: stainless steel, brass

Minimum pressure difference: 0.1Mpa surface treatment: epoxy coating
