The Company has secured a back-pressure valve Flexible Zhini patent certificate by the national patent protection, becoming the only one with the patent certificate Yazui valve manufacturer, and has passed the ISO9001 quality system certification, And the national testing standards for product quality and credibility of the country and ensure that enterprises.

本公司已经获得了背压式柔性止逆阀专利证书，得到国家专利保护，成为国内唯一一家具有鸭嘴阀专利证书的生产厂家，并且已经通过了ISO9001质量体系认证，并且是国家检测连续达标产品及全国质量稳定信誉保证企业。

And pulsation damper used simultaneously, the pulsation damper to be an in between pumps and back-pressure Bellows Seal Valves valve in order to absorb the pump and back-pressure valve between the flow peak.

与脉动阻尼器同时使用时，脉动阻尼器应安在泵与背压阀间，以吸收泵与背压阀间的流量峰值。

For the stability of the flow metering pumps, metering pump flow rate, as some big changes with pressure, you can set the exit of metering pump back-pressure valve, so that the output of metering pump flow rate stability, and then usually selected back-pressure valve The Reducing Valves pressure of the actual use of a metering pump metering pump pressure or slightly less than the use of pressure.

用于稳定计量泵的流量，如某些计量泵的流量随压力变化较大，可在计量泵的出口处设置背压阀，使计量泵的输出流量稳定，这时一般选择背压阀的压力为计量泵的实际使用压力或略小于计量泵的使用压力。

Warning: The back-pressure valve prior to any maintenance, should stop functioning equipment, the release of pressure, Plug Valves close the back-pressure valve valves associated with the system, while recognizing that there is no pressure pulsation damper.

警告：对背压阀进行任何维护以前，应停止运转设备，释放压力，关闭背压阀与系统相联的阀门，同时确认脉动阻尼器内没有压力。

So as technology advances, balance valve (PH45F) to replace the valve.

于是随着技术的进步，平衡阀(PH45F)代替了调节阀。

We mainly produce manual, pneumatic, electric control valve, KPF balance valve and many other products.

我厂主要生产手动、气动、电动调节阀、KPF平衡阀等多种产品。

A cut-off function, the installation of the balance valve will not have to install the valve.

有截止功能，安装了平衡阀就不必再安装截止阀。

The methods of selection, installation, operation and regulation of the balance valve were introduced based on the properties of the valve in one heating system.

阐述了平衡阀的选型原理，并以一个供暖系统为例，说明了平衡阀的选型和在供暖系统中安装要求，并介绍了在热水供暖系统中平衡阀的两种调试方法。

It is worth mentioning that, a combination of the above-mentioned advantages of the valve is about to launch a new type of balance valve, it does not need to use instrumentation, debugging simple and quick, the workload of small, low prices, applicable to steady-state system, I believe it will be users.

值得一提的是，一种综合了上述阀门的优点的新型平衡阀即将面世，它不需要用仪表，调试简便快捷，工作量小，价格较低，适用于稳态系统，相信它会受到用户的欢迎。

According to different flows, the pressure balance spool valve can be pre-pressure, can also be a back pressure valve (external to the center of the flow).

根据流向不同，平衡阀芯所受的压力可以是阀前压力，也可以是阀后压力。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
