一、進口超高壓電動調(diào)節(jié)閥描述：

德國《LOCKE》洛克進口超高壓電動調(diào)節(jié)閥采用鍛造閥體，采取多級籠式對稱小孔套筒組成的閥芯結(jié)構(gòu)，完全控制了流過閥內(nèi)的介質(zhì)的流速，大幅度的降低了高壓氣體或者蒸汽在閥內(nèi)產(chǎn)生的噪音，穩(wěn)定的多級別降壓有效使液體不會產(chǎn)生氣蝕，是使用在高壓介質(zhì)場所性能穩(wěn)定的控制閥，最高使用壓力可達到80Mpa，4500Lb，用于火電的高壓系統(tǒng)、礦井下的高壓系統(tǒng)的電動調(diào)節(jié)閥，產(chǎn)品經(jīng)過多次的改進，不繼完善，具有新穎性和先進性。

German "locke" imported ultra-high pressure electric control valve adopts forged valve body, adopts multi-stage cage type symmetrical small hole sleeve valve core structure, completely controls the flow rate of medium flowing through the valve, greatly reduces the noise generated by high-pressure gas or steam in the valve, stable multi-level pressure reduction effectively prevents liquid from cavitation, which is used in high-pressure medium places The stable control valve can reach 80Mpa and 4500Lb at the highest pressure, and is used in the electric control valve of the high pressure system of the thermal power plant and the high-pressure system under the mine. The product has been improved many times, and is not perfect, and has novelty and advanced nature.

二、進口超高壓電動調(diào)節(jié)閥結(jié)構(gòu)特征：

1．本系列產(chǎn)品采用完合拆裝式結(jié)構(gòu)，操作力距小，閥腔內(nèi)件（包括閥座、閥芯、節(jié)流組件、密封件等）均可從并閥腔取出，維護保養(yǎng)十分方便，閥體不需從管道上割下，可長期使用。

2．閥芯為柱塞體平衡式結(jié)構(gòu)，操作力距小，調(diào)節(jié)靈敏高。

3．節(jié)流組件由多孔板集流式節(jié)流環(huán)與套筒式節(jié)流套組成，且配以均流罩，因此具有小流量高壓差無氣蝕、大流量、調(diào)節(jié)性能好，流體排出梳流無噪音的綜合特性，完全滿足了高壓差等苛刻工況的要求，有效地實現(xiàn)了高溫、高壓差流體的流量調(diào)節(jié)控制，可調(diào)性好，調(diào)節(jié)精度高。

4．節(jié)流環(huán)可在閥門工作行程的55%之內(nèi)，實現(xiàn)多級減壓節(jié)流。

5．閥芯和閥座密封面堆焊司鈦萊硬質(zhì)合金，抗沖刷、耐腐蝕。

1. This series of products adopt the structure of complete disassembly and assembly, and the operating force distance is small. The parts in the valve cavity (including valve seat, valve core, throttling components, seals, etc.) can be taken out from the valve chamber. The maintenance is very convenient. The valve body does not need to be cut off from the pipeline, so it can be used for a long time.

2. The valve core is a plunger body balanced structure, with small operating force distance and high adjustment sensitivity.

3. The throttling assembly is composed of a perforated plate collecting throttle ring and a sleeve type throttling sleeve, and is equipped with a flow equalizing cover. Therefore, it has the comprehensive characteristics of small flow, high pressure difference, no cavitation, large flow, good regulation performance, and no noise of fluid discharge comb flow. It fully meets the requirements of harsh working conditions such as high pressure difference, and effectively realizes the flow regulation control of high temperature and high pressure difference fluid High precision.

4. The throttle ring can realize multi-stage decompression and throttling within 55% of valve working stroke.

5. The sealing surface of valve core and valve seat is overlaid with Stellite hard alloy to resist erosion and corrosion.
