逻辑阀的选型窍门:   1、在选用逻辑阀时,应根据系统所需的流量,大于或等于200l/min时选用二通插装阀,小于20l/min则选用螺纹插装式逻辑阀。插装组件的阀芯有带尾部和不带尾部形式,带尾部的有缓冲和节流等作用。阀芯还有多种面积比可供选择,弹簧也有多种刚度可供选择,从而实现多种开启压力。    2、国内有的插装组件在阀芯和阀套之间装有O形圈,这样能确保密封,但反应速度慢。控制盖板和阀芯中的阻尼孔有多种直径,阻尼孔大反应速度快,但冲击大,阻尼孔小则反之。如果逻辑阀的动作有先后会影响系统的功能时,在选择阻尼孔的直径时,应特别慎重。控制盖板的型号很多,应根据系统情况仔细选择。   3、设计阀块时应画上盖板的定位孔,并标明各个油口的代号,以便装配和维修。应根据系统的流量和压力及其流量-压力曲线选型,过小往往会造成系统压力损失太大,使系统发热,若选型过大,则会使系统庞大,造成经济上的浪费。   4、逻辑阀有二种密封材料可选,氟橡胶密封适用于磷酸脂介质,丁腈橡胶密封适用于矿物油介质。   5、逻辑阀由于其高压大流量的特点特别适用于阀门快速液压驱动装置,在国内外都有成熟的逻辑阀产品,其在阀门快速液压驱动装置的应用前景是广阔的。

译文:
Logic valve selection tips: The selection of two way cartridge valves in the selection of the logic valve should be based on the flow of the system required greater than or equal to 200l/min less than 20l/min threaded cartridge logic valve is selected. Cartridge component of the spool with the tail and the tail without form, with the tail of the buffering and throttling. Spool there are a variety of area ratios are available, spring is also a variety of stiffness in order to achieve a variety of opening pressure. Domestic cartridge components are equipped with O-ring between the spool and sleeve, so to ensure that the seal, but the reaction was slow. Control cover and spool orifice in a variety of diameter orifice fast response, but the impact is large, the orifice is small and vice versa. If the logic valve action has will affect the function of the system, should be particularly careful in the choice of the diameter of the orifice. Control cover model, should be carefully selected according to the system case. 3, the design of valve block should be painted on the cover of positioning holes, and marked with the code in each port, so that the assembly and maintenance. Should be based on the system flow and pressure and flow – pressure curve selection, often too small will cause the system pressure loss is too large to make the system heat, if the selection is too large, you will make a huge system, resulting in economic waste. 4, there are two kinds of logic valve sealing material optional, Viton seals for phosphate medium, NBR seals for mineral oil medium. 5, the logic valve is particularly applicable because of its high-pressure flow characteristics in the fast valve hydraulic drive, mature logic valve products at home and abroad, and its applications are broad prospects in the fast valve hydraulic drive.

针型阀的的的防腐

针型阀的的的防腐

原文:首先阀体的防腐蚀,主要选用材料为不锈钢,碳钢。虽然防腐蚀的资料十分丰富,但能否选得恰当,还是不容易的事情,因为腐蚀的问题很复杂。选择阀体材料的难处,还在于不能只考虑腐蚀问题,同时必须考虑耐压耐温能力,经济上是否合理,购买是否容易等因素。其次是采取衬里措施,如衬铅、衬铝、衬工程塑料、衬天然橡胶及各种合成橡胶等。如介质条件许可,这倒是一种节约的方法。再次,在压力、温度不高的情况下,用非金属做阀门主体材料,往往能十分有效地防制腐蚀。此外,针型阀阀体外表面还受到大气腐蚀,一般钢铁材料都以刷漆来防护。针型阀的的的防腐?

First of all, the body of anti-corrosion, main material is stainless steel, carbon steel. Although the anticorrosion material is very rich, but can choose well, or not easy thing, because the problem of corrosion is very complex. Difficulty of the body material choice, is not only considered corrosion problem, the pressure must be considered and heat-resistant ability at the same time, the economic is reasonable, whether the purchase easy and other factors. Followed by lining measures, such as lining, lining aluminum, lead lining engineering plastics, lining natural rubber and various synthetic rubber, etc. Such as medium conditions permit, it’s a way to save. Again, in the case of pressure, temperature is not high, the use of non-metallic in the valve body material, often can effectively control the corrosion. In addition, the needle valve body surface by atmospheric corrosion, general steel material is to brush paint protection.针型阀的的的防腐?
