一、進(jìn)口電動(dòng)多級(jí)調(diào)節(jié)閥描述：

德國(guó)《LOCKE》洛克進(jìn)口電動(dòng)多級(jí)調(diào)節(jié)閥采用的是多級(jí)籠式套筒閥芯或軸流迷宮型閥芯，多級(jí)減壓，完全控制流過閥內(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(jí)別降壓有效使液體不會(huì)產(chǎn)生氣蝕，是使用在高壓介質(zhì)場(chǎng)所性能穩(wěn)定的控制閥。

電動(dòng)執(zhí)行機(jī)構(gòu)為一體化結(jié)構(gòu)，內(nèi)有伺服放大器,輸入控制信號(hào)(4～20mADC或1～5VDC)及電源即可控制閥門開度，達(dá)到對(duì)壓力、流量、液位、溫度等工參數(shù)的調(diào)節(jié)。電動(dòng)多級(jí)調(diào)節(jié)閥整體具有動(dòng)作靈敏、連線簡(jiǎn)單、流量大、體積小、調(diào)節(jié)精度高等特點(diǎn)。

Germany "locke" imported electric multi-stage control valve adopts multi-stage cage sleeve valve core or axial-flow labyrinth valve core. It can fully control the flow rate of medium flowing through the valve, greatly reduce the noise generated by high-pressure gas or steam in the valve. The stable multi-level pressure reduction effectively prevents the liquid from cavitation. It has stable performance when used in high-pressure medium Control valve.

The electric actuator is an integrated structure with servo amplifier. The valve opening can be controlled by inputting control signal (4 ~ 20mADC or 1 ~ 5VDC) and power supply, so as to adjust the working parameters such as pressure, flow, liquid level and temperature. The electric multi-stage control valve has the characteristics of sensitive action, simple connection, large flow, small volume and high regulation accuracy.

Design features

Continuous adjustment within the range of high pressure difference

The sleeve structure is porous cage type, arranged strictly according to the required adjustment characteristics, with good adjustment performance.

The upper and lower parts of the valve core are equipped with guide, adjusting balance, no vibration and strong self-cleaning ability.

The valve core can be designed as balanced type and non-equilibrium type. The balanced type has a sealing ring at the balance hole, and the non-equilibrium type uses conical surface sealing, which has good sealing effect..

The medium flows in axial direction, and gradually depressurizes after multi-stage throttle disc. It can resist cavitation when bearing large pressure difference and has low noise.

The valve seat has a conical sealing surface to achieve reliable sealing when the valve is closed.

The sealing surface is overlaid with cemented carbide, and the surface of valve core (rod) is sprayed with cemented carbide material, which is erosion resistant and has long service life.

application

Drain water from high pressure inner and outer cylinder pipes and main control valve of steam turbine.

Drain water from IP cylinder, IP control valve, LP cylinder and each extraction system.

Water spray desuperheating of boiler superheater.

High pressure bypass and various desuperheating systems spray water with high pressure difference.

Feed water recirculation, feed water bypass valve, periodic blowdown system, etc.

Other media adjustment under high pressure difference environment.
