二、進(jìn)口氣動(dòng)隔膜閥結(jié)構(gòu)優(yōu)點(diǎn)：

1、結(jié)構(gòu)緊湊、簡(jiǎn)單、體積小，外形美觀；

2、開關(guān)有導(dǎo)向，運(yùn)動(dòng)平穩(wěn)；關(guān)閉力矩小，壽命長(zhǎng)，≥30萬次；

3、膜片壓緊可自動(dòng)調(diào)整，受壓均勻，密封可靠；膜片裝入閥芯采用推入式，更換方便。

4、氣動(dòng)隔膜閥尚可附裝反饋信號(hào)、限位器或定位器，以適應(yīng)自近控、程控或調(diào)節(jié)流量的需要。

5、氣動(dòng)閥門的反饋信號(hào)采用無觸點(diǎn)傳感技術(shù)。

6、采用氣缸活塞式。

7、當(dāng)氣源發(fā)生故障時(shí)，可操作手輪使閥門開啟。

1. Compact structure, simple, small size, beautiful appearance;

2. The switch has guidance and smooth movement; the closing torque is small and the service life is long, ≥ 300000 times;

3. The pressure of diaphragm can be adjusted automatically, the pressure is even, and the seal is reliable; the diaphragm is installed into the valve core by push in type, which is convenient for replacement.

4. The pneumatic diaphragm valve can also be equipped with feedback signal, limiter or positioner to meet the needs of close control, program control or flow regulation.

5. The feedback signal of pneumatic valve adopts contactless sensing technology.

6. Adopt cylinder piston type.

7. When the air supply fails, the hand wheel can be operated to open the valve.

三、進(jìn)口氣動(dòng)隔膜閥描述：

德國(guó)《LOCKE》洛克進(jìn)口氣動(dòng)隔膜閥由隔膜閥和氣動(dòng)執(zhí)行機(jī)構(gòu)兩部分組成，它以壓縮空氣為動(dòng)力，實(shí)與對(duì)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(dòng)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(diǎn)，廣泛適用于工業(yè)自動(dòng)化系統(tǒng)中的強(qiáng)酸、強(qiáng)堿、強(qiáng)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)。

Locke pneumatic diaphragm valve is composed of two parts: diaphragm valve and pneumatic actuator. It is driven by compressed air and regulates the flow of fluid medium in the process pipeline. As the valve body with corrosion-resistant lining and corrosion-resistant diaphragm, stuffing box free structure, elastic diaphragm as throttling element and smooth flow passage of the valve body are adopted in the structure, the pneumatic diaphragm valve has the advantages of small negative force, large installation flow, no leakage, convenient and reliable, fire and explosion-proof, which is widely applicable to the strong acid, strong alkali, strong corrosion, high viscosity and containing in industrial automation system Flow regulation of spikelets, fibrous media and toxic and non polluting media.
