压力开关是我们生活中经常使用的东西。有很多种开关我们不知道，比如压力开关。压力开关具有压力检测、显示压力尺寸、报警和控制压力信号输出的多种功能。今天川消小编为您解答：
Pressure switch is often used in our life. There are many kinds of switches we don't know, such as pressure switches. The pressure switch has the functions of pressure detection, pressure size display, alarm and pressure signal output control. Today, Sichuan Xiaobian answers:
压力开关精度高，性能稳定。广泛应用于石化、冶金、电力、供水等行业测量不同液体等表面压力和绝压。金宝和控制是一种智能检测和控制仪器。
The pressure switch has high precision and stable performance. It is widely used in petrochemical, metallurgy, electric power, water supply and other industries to measure the surface pressure and absolute pressure of different liquids. Jinbaohe control is an intelligent detection and control instrument.
压力开关的工作原理是，如果压力开关系统中的压力高于或小于初始设定的压力值，压力开关中传感器中的光盘可以及时感应和报警，同时移动。通过与导杆连接，压力开关的接头可以连接或断开。
The working principle of the pressure switch is that if the pressure in the pressure switch system is higher or lower than the initially set safety pressure value, the optical disc in the sensor in the pressure switch can sense and alarm in time and move at the same time. By connecting with the guide rod, the connector of the pressure switch can be connected or disconnected.
当压力开关系统中的压力恢复到初始设定的压力值时，光盘可以及时感知，然后在瞬间恢复到原始位置，开关将自动恢复到原始位置和状态。需要注意的是，我们需要了解压力开关的调整方法。让我们具体看看：
When the pressure in the pressure switch system is restored to the initially set safety pressure value, the disc can be sensed in time, and then it will instantly return to the original position, and the switch will automatically return to the original position and state. It should be noted that we need to understand the adjustment method of the pressure switch. Let's take a specific look:
1.选择0.1~1.0Mpa的压力控制器(JC-210，HNS-210)
1. Select 0.1~1.0mpa pressure controller (jc-210, hns-210)
2.旋转顶部右侧的压力调节螺钉，将指针指示在0.8Mpa(8kg或8bar)的上限切换值。
2. Rotate the pressure adjusting screw on the right side of the top to indicate the upper limit switching value of 0.8MPa (8kg or 8bar).
3.旋转顶部左侧的压力调节螺钉，使指针指示在0.3mpa标准尺上，下限切换值=上限切换值-开关压差=0.8-0.3=0.5，为下限切换值。
3. Rotate the pressure adjusting screw on the left side of the top to make the pointer indicate on the 0.3MPa standard. The lower limit switching value = upper limit switching value - switching differential pressure =0.8-0.3=0.5, which is the lower limit switching value.
川消压力开关主要包括常开式和常闭式。其主要特点是：采用螺纹快速接头或铜管焊接安装结构，安装灵活，使用方便，无需特殊安装和固定。插入式导线连接可供用户选择。密封不锈钢传感器。根据客户需要的压力在压力范围内制造。
Pressure switches mainly include normally open and normally closed. Its main features are: the use of threaded quick connectors or copper pipe welding installation structure, flexible installation, easy to use, without special installation and fixation. Plug in wire connection is available for users to choose. Sealed stainless steel sensor. It is manufactured within the pressure range according to the pressure required by the customer.
