進口氣動隔膜閥德國洛克品牌產(chǎn)品特點

 

進口氣動隔膜閥結(jié)構(gòu)特點：

1.隔膜閥與其它閥門的區(qū)別在於：采用無填料函的構(gòu)造；橡膠隔膜可使流道內(nèi)的腐蝕性介質(zhì)與所有驅(qū)動部件處於完全隔離的狀態(tài)，從而杜絕了通常閥門的“跑、冒、滴、漏”等弊端。

2.由於隔膜閥的流道平滑，流阻小，故而可獲得較大的流量。

3.視膠隔膜閥的閥體內(nèi)腔表面視復(fù)有廳供選擇的多種橡膠。因此具有優(yōu)越的耐腐蝕的特點。

4.由於密封件為富有彈性的橡膠隔膜。因此還具有較好的密封性和最小的關(guān)閉力。

5.本閥由閥體、閥蓋、閥瓣、閥桿、隔膜和其它驅(qū)動零件等組成。

6.閥門的啟閉是依靠旋轉(zhuǎn)手輪而達到的。隔膜閥在閥蓋上端標有可窺見閥門處啟或閉位置的顯示色別，以指示閥門的啟閉行程。當順時針放置手輪時，手輪即下移，閥瓣隨之帶動隔膜下降使通路截斷；反之則閥門即開啟，色別隨之顯露。

進口氣動隔膜閥工作原理：

1、采用橡膠或塑料等軟質(zhì)密封制作的隔膜，密封性較好。由于隔膜為易損件，應(yīng)視介質(zhì)特性而定期更換。

2、受隔膜材料限制，隔膜閥適用于低壓和溫度相對不高的場合。

3、隔膜閥按結(jié)構(gòu)形式可分為：屋式、直流式、截止式、直通式、閘板式和直角式六種；連接形式通常為法蘭連接；按驅(qū)動方式可分為手動、電動和氣動三種，其中氣動驅(qū)動又分為常開式、常閉式和往復(fù)式三種。

4.一般不宜用于溫度高于60度及輸送有機溶劑和強氧化介質(zhì)的管路中，也不宜在較高壓力的管路中使用氣動隔膜閥。

 

進口氣動隔膜閥簡介：

德國洛克 《DE LOCKE 》進口氣動隔膜閥由隔膜閥和氣動執(zhí)行機構(gòu)兩部分組成，它以壓縮空氣為動力，實與對工藝管道中流體介質(zhì)流量的調(diào)節(jié)。由于在結(jié)構(gòu)上采用帶有耐腐蝕襯里的閥體和耐腐蝕的隔膜、無填料函結(jié)構(gòu)、節(jié)流元件為彈性隔膜、閥體流道平滑，故氣動薄膜隔膜閥具有陰力小，安裝流量大、無外漏和方便可靠、防火防爆的優(yōu)點，廣泛適用于工業(yè)自動化系統(tǒng)中的強酸、強堿、強腐蝕、高粘度、含穎粒、帶纖維以及有毒和不充許污染的介質(zhì)的流量調(diào)節(jié)。

Introduction of imported pneumatic diaphragm valve:
The pneumatic diaphragm valve imported from German Locke is composed of diaphragm valve and pneumatic actuator. It uses compressed air as power to regulate the flow of fluid medium in process pipeline. Because the valve body with corrosion resistant lining and corrosion-resistant diaphragm, packing free structure and throttle element are elastic diaphragm and valve body flow path are smooth, the pneumatic diaphragm valve has the advantages of low negative force, large installation flow, no leakage, convenience, reliability, fire and explosion-proof, and is widely used in industrial automation system with strong acid, strong alkali, strong corrosion, high viscosity, and containing Flow regulation of spikelets, fibrous media and toxic and uncontaminated media.
                                                                               

進口氣動隔膜閥用途：

用于控制非腐蝕性或一般腐蝕性介質(zhì)，閥體內(nèi)腔表面無襯里或覆有可供選擇的各種橡膠，適用于不同工作溫度和流體管路。適用溫度:≤85℃、≤100℃、 ≤120℃、≤150℃(按照襯里和隔膜材料)采用橡膠或塑料等軟質(zhì)密封制作的隔膜，密封性好。

受隔膜材料限制，隔膜閥適用于低壓和溫度相對不高的場合。

一般不宜用于溫度高于60度及輸送有機溶劑和強氧化介質(zhì)的管路中，也不宜在較高壓力的管路中使用氣動隔膜閥。

Purpose of imported pneumatic diaphragm valve:
It is used to control non corrosive or general corrosive medium. The surface of the valve body cavity is unlined or covered with various rubber which can be selected, and it is suitable for different working temperature and fluid pipeline. Applicable temperature: ≤ 85 ℃, ≤ 100 ℃, ≤ 120 ℃, ≤ 150 ℃ (according to lining and diaphragm materials), the diaphragm made of rubber or plastic soft seal has good sealing performance.
Limited by diaphragm material, diaphragm valve is suitable for low pressure and relatively low temperature.
Generally, it is not suitable for pipelines with temperature higher than 60 ℃ and transporting organic solvent and strong oxidation medium, and pneumatic diaphragm valve should not be used in pipelines with high pressure.
