减压

How it works: decompression works is the use of diaphragm, spring and piston and other sensitive components, to change the valve core and valve seat of the gap to achieve the automatic decompression purposes.

工作原理：减压工作原理是利用膜片、弹簧和活塞等敏感元件，改变阀芯与阀座的间隙来达到自动减压的目的。

Valve is the use of diaphragm, spring, piston and other sensitive components to change the valve clearance between the valve and valve seat, when the medium when produced by throttling, the pressure drop and its decompression valve.

减压阀是利用膜片、弹簧、活塞等敏感元件改变阀瓣与阀座之间的间隙，当介质通过时产生节流，压力下降而使其减压的阀门。

Therefore, the piston valve to be installed before the filter; for new installations or long-term out of the Balance Valves valve, must be open inspection and cleaning.

所以，活塞减压阀前必须安装过滤器；对于水力控制阀新安装或长期停用的减压阀，一定要拆开检查和清洗。

When the load smaller than the first outlet pressure adjustment valve set pressure, pilot valve Poppet head off an oil chamber, oil chamber 2 is equal to the pressure on the outlet pressure, the main valve of the sliding shaft 2 inside the cavity in the oil a rigid under the action of a small spring at the lowest position, the main valve and the valve slider protruding shoulder posed by all the valve port opens, pressure reducing valve without decompression.

当负载较小，出口压力低于先阀的调定压力时，先导阀的提动头关闭，油腔1、油腔2的压力均等于出口压力，主阀的滑轴在油腔2里面的一根刚性很小的弹簧作用下处于最低位置，主阀滑轴凸肩和阀体所构成的阀口全部打开，减压阀无减压作用。

Like the single-stage regulator, outlet pressure from the first stage of the two-stageregulator rises as cylinder pressure decreases.

同单级减压阀一样，两级减压阀的第一级的出口压力随钢瓶压力的降低而升高。

In a system with only one pump, reduced pressure for one branch of the circuit can be obtained with a pressure-reducing valve.

在只有一个泵的系统中，为一条支路减压可通过减压阀完成。

If the system is not rated for full cylinder pressure, a pressure-reducing regulator must be used and the system should be protected with a pressure-relief device.

如果系统额定压力低于满瓶的压力，必须使用减压调整器，同时应该用减压装置来保护系统。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
