SV615安全閥:全行程、全噴嘴安全閥。適用于蒸汽、空氣不起化學(xué)作用的工業(yè)氣體和非危險(xiǎn)液體的應(yīng)用。用于蒸汽或熱水鍋爐，發(fā)生器、壓力容器、儲(chǔ)氣罐和空氣壓縮機(jī)，高壓釜減壓閥的下游保護(hù)等。

口徑DN15~50，壓力PN25,螺紋BSP或NPT連接，對(duì)于DN15~25可提供衛(wèi)生級(jí)卡箍連接。密封性能符合API527標(biāo)準(zhǔn)。可提供軟密封閥芯。SV607/SV604安全閥:全行程法蘭連接安全閥。主要應(yīng)用于蒸汽鍋爐管道。壓力容器、壓縮機(jī)和儲(chǔ)氣罐等的防護(hù)及大多數(shù)的工業(yè)過(guò)程設(shè)備的防護(hù)。

符合DIN320 TRD421的要求，具有TUV認(rèn)證，口徑DN20~DN150，SV607壓力級(jí)為PN16/25，SV604為PN40/AN300，可提DIN標(biāo)準(zhǔn)法蘭和ANSI標(biāo)準(zhǔn)法蘭。密封性能符合API527標(biāo)準(zhǔn)。根據(jù)客戶要求可提供軟密封閥芯。

    英國(guó)斯派莎克安全閥設(shè)計(jì)*，品種齊全，材質(zhì)廣泛(青銅、球鐵、碳鋼、合金鋼、不銹鋼等材質(zhì))，使用溫度范圍廣泛，所有產(chǎn)品均有機(jī)構(gòu)的認(rèn)證。，能提供符合不同標(biāo)準(zhǔn)要求的安全閥。

在減壓站系統(tǒng)中，為了防止減壓閥下游壓力高于設(shè)備運(yùn)行的額定壓力，減壓閥下游必須安裝安全閥。安全閥的設(shè)定壓力必須在設(shè)備運(yùn)行的zui大許可壓力范圍內(nèi)，并與正常的運(yùn)行壓力間有足夠的壓差，以防止安全閥頻繁起跳導(dǎo)致密封面損傷。安全閥的設(shè)定必須由有資格人員來(lái)進(jìn)行。在安全閥選型時(shí)，應(yīng)保證安全閥在設(shè)定壓力下能通過(guò)減壓閥所能流過(guò)的zui大流量。

 Introduction

    SV615 whole trip , the whole nozzle valve for steam, air , application role can not afford chemical inert industrial gases and non- hazardous liquids.

Application

SV615 safety valve : the whole trip , the whole nozzle valve . Suitable for the application of steam , air can not afford chemical industrial gases and non- hazardous liquids . For steam or hot water boilers, generators , pressure vessels , gas tank and air compressor , autoclave valve downstream protection.

Diameter DN15 ~ 50, the pressure PN25, BSP or NPT threaded connections DN15 ~ 25 provides for sanitary clamp connections . Sealing performance meets API527 standards. Provides a soft seal spool . SV607/SV604 safety valve : full stroke valve flange connection . Mainly used in steam boiler pipes. Pressure vessels, compressors and cylinders and other protective guard and most of the industrial process equipment.

Comply with the requirements of DIN320 TRD421 with TUV certification , caliber DN20 ~ DN150, SV607 pressure level is PN16/25, SV604 is PN40/AN300, can provide standard flanges and ANSI standards DIN flanges . Sealing performance meets API527 standards. According to customer requirements to provide a soft seal spool .

    Spirax Sarco advanced valve design , full range , the material widely ( bronze, ductile iron , carbon steel, alloy steel, stainless steel and other materials ) , widely used in the temperature range , all products are certified authority . To provide a safety valve meets the requirements of the different standards .

In the vacuum station system, in order to prevent the rated pressure relief valve downstream pressure is higher than the equipment operation , valves must be installed downstream of the valve . Pressure relief valve must be set within the maximum allowable operating pressure range of the device between the normal operating pressure and there is enough pressure to prevent the valve sealing surface damage resulting in frequent jump . Relief valve setting must be performed by qualified personnel. When the safety valve selection should guarantee the safety valve set pressure through the valve can flow through the maximum flow .

The following parameters:

1 , system or equipment must displacement and the proposed number of valves installed .

2, the opening pressure ( or set pressure )

3 , and the proportion of medium (liquid medium ) or molecular weight and compressibility factor ( for gaseous media )

4, the valve inlet medium temperature

5 , if there is back pressure , if any, is the number

6 , requires valve performance standards ( eg no special specified , specified by the supplier
