The disadvantage is, that inappropriate use may result in spillage.

采样阀的缺点，是有可能因为操作不当而造成流体溢出。

Look for any signs of leaking between the gun and the unloader valve.

检查一下水枪和减压阀是否有泄漏的迹象。

When the thrust balance with the pressure regulator spring force when the pressure valve will have a stable output.

当该推力与调压弹簧作用力相平衡时，阀便有稳定的压力输出。

The pressure regulator valve direct-acting methods are two kinds of type and Pilot.

减压阀的调压方式有直动式和先导式两种。

The other is a larger exhaust resistance, such as a valve in the exhaust pipe on the road, small pipe, large damping sensors, non-specific silencer in the exhaust below the liquid level, the gas discharged into the closed or semi-closed containers.

另一类是排气阻力较大，比如在排气管路上有阀、细小弯管、大阻尼传感器、非专用的消音器、在液面以下排气、气体排往密闭或半密闭容器等。

Schwing poppet valve hydraulic piston pump be used in many municipal and industrial projects world wide.Today,Schwing was recognized as technology leader of"Dewatered sludge Pumping System".Schwing pump can pumping the sludge even with 56%solid content,for other inorganic material even with 80%solid content.Schwing units have operated continuously for years with 99%availablity.For sludge storage,Available in circular or rectangular design,the sliding frame/push floor technologies provide low cost methods to store large volumes of material w你好le awaiting final disposal.Schwing sliding frame system in the bottom of the silo,disc harge the sludge with the screw into sludge truck or Schwing pump.The typical installation is silo with pump installed beside the dewatering mac你好ne.A Schwing silo can be integrated into the process stream to equalize surges in solids production and subsequently meter cake to final disposal.Large diameter storage silos are useful for truck loading,and finally,both sliding frame and push floor designs are effective as receiving stations used to accept sludge hauled in from other facilities.Ultimately,the storage volume of the silos and bunkers dictate the plant''s flexibility in disposing of the solids.

施维英的晋升阀液压柱塞泵广泛应用活着界规模内的城市管理工作以及工业污泥输送项目今日，施维英被公以为是世界规模内&脱水污泥泵送体系&的科学技术带领者施维英泵可以泵送固体含量达56%的活性有生命的物质脱水污泥，甚或者固体含量达80%的非有生命的物质其它稀浆与污泥施维英泵颠末多年不中断地事情，靠患上住性仍维持在99%施维英滑架体系位于料仓的底部，可以将污泥排入卡车或者施维英泵中用来暂存污泥以及装车的料仓较典型的应用是以及施维英污泥泵一路被安装在污泥脱水举措措施相近施维英料仓在污水措置惩罚厂的预设中首要负担3种脚色，料仓被集成处措置惩罚流程之中，均衡物料出进，并对终极排出的污泥计量料仓用于装车料仓的储存体积说了然污水措置惩罚厂措置惩罚污泥的规模料仓可以用来吸收暂存从其它污水厂送来的污泥，尔后送到后续污泥措置惩罚装备中滑架技能已在被证实是最具国际性最有用率的技能

The Laiwu Steel Group Special Steel County 50 tons electric furnace electrode regulator is the analogous circuit plug-in unit type product at the beginning of 80 ages last century .because the primary device gets older and the damage is serious, which creates the system failure rate to be high and the smelting electricity consumes high.

因此，根据技术进步要求对其进行数字化改造。通过对电炉的炼钢工艺进行分析发现必须有电极的阻抗控制和保护电极和保护炉墙等功能，通过对电气系统的分析可以得到必须有短路、过电流和保护开关的功能，通过对液压机械性能进行了分析和测试发现液压阀存在死区需要进行补偿。

If the reading returns to +psid, No. 2 shutoff valve is leaking excessively, and must be replaced to test the valve.

如果读数变为+psid，则2号关闭阀就有过量的泄漏，并且必须更换并检测这个阀门。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
