进口电动V型调节球阀产品概述：

德国《LOCKE》洛克--进口电动V型调节球阀是一种芯阀座采用金属，或金属对聚四氟乙烯密封配合的旋转球阀，它将球阀和蝶阀的控制特性结合成一体,既可用作控制调节阀，又可作关断切断阀；LDRV型电动V型调节球阀为电动单元组合仪表中执行单元，可实现比例调节，接收ON-OFF或4-20mAC或1-5VDC的信号进行比例动作的小型、坚固、高精度的电动执行机构，动作灵敏，并采用转角直接指示和反馈，广泛应用于石油、化工、造纸、冶金、污水处理等行业，实现管道中介质流量调节和切断，以达到生产过程按一定的规范进行。

进口电动V型调节球阀产品特点：

（１）不带任何管接头的整体式阀体，因此不受管道或螺栓应力影响，并且由于阀体无任何管接头，故耐压壳体不会受压力“突变”的影响；

（２）具有一个Ｖ型阀体，即使在小流量或高粘度介质的情况下，也可在整个量程范围内，保证控制的精确性；

（３）防漏耐用的阀座在其外径处衬有带不锈钢内芯ＰＴＦＥ杯形或是Ｏ型密封圈，阀座用截面较大的钨钴硬合金制成，通过一个合金的波纹弹簧进一步增强了阀座的结构；

（４）当阀门关闭时，Ｖ型缺口与阀座之间产生楔形剪切作用，并既具有自洁功能又可防止球芯卡死，特别适用于管线结垢冻结或含有纤维和颗粒固体场合。 适用于高粘度、悬浮液、纸浆等不干净、含纤维介质场合。采用直连方式与执行机构连接，具有结构紧凑、尺寸小、重量轻、阻力小、动作稳定可靠等优点。

Introduction of imported electric V-type regulating ball valve products:

Locke imported electric V-type regulating ball valve is a kind of rotary ball valve with metal core seat or metal to polytetrafluoroethylene seal. It combines the better control characteristics of ball valve and butterfly valve, and can be used as both control regulating valve and shut-off valve; LDRV type electric V-type regulating ball valve is the executive unit of the electric unit combination instrument, which can realize the proportional adjustment, receive the signal of on-off or 4-20mac or 1-5vdc for proportional action. It is a small, solid and high-precision electric actuator with sensitive action and direct indication and feedback of rotation angle. It is widely used in petroleum, chemical, paper making, metallurgy, sewage treatment and other industries, Realize the medium flow regulation and cut-off in the pipeline, so as to achieve the production process according to certain specifications.

Features of imported electric V-type regulating ball valve:

(1) The integral valve body without any pipe joint is not affected by pipeline or bolt stress, and the pressure shell will not be affected by pressure "mutation" because the valve body has no pipe joint;

(2) With a V-shaped valve body, even in the case of small flow or high viscosity medium, it can also ensure the accuracy of control in the whole range;

(3) The leakage proof and durable valve seat is lined with PTFE cup or O-ring with stainless steel inner core at its outer diameter. The valve seat is made of tungsten cobalt cemented carbide with large cross section, and the structure of the valve seat is further enhanced by a corrugated spring of alloy;

(4) When the valve is closed, wedge shear action occurs between the V-notch and the valve seat. It has self-cleaning function and can prevent the ball core from sticking. It is especially suitable for pipeline scaling and freezing or containing fiber and particle solids. It is suitable for high viscosity, suspension, pulp and other unclean and fibrous media. It is connected with the actuator directly, which has the advantages of compact structure, small size, light weight, small resistance, stable and reliable action.
