In the petroleum, chemical, metallurgical and energy industries, the valve is one of the widely used fluid control equipment.
high temperature solenoid valve As an important part of the piping system, a lot of specifications and types of valves, the role of different. Some used to connect or cut off media, adjust the media pressure or flow, to prevent the medium pressure exceeds a predetermined value, and to ensure the safe operation of the pipeline or equipment. Some to separation, mixing or distribution medium, to ensure that the system process conditions. Due to the role of the valve in the piping system, will directly affect the manufacturing process of the valve to the safe operation of the pipeline equipment. Therefore, the "pressure piping components manufacturing security registration and management approach", the manufacturing unit of the valve should accept the security registration, only the valve the Security Registration manufacturing unit production can be used for pressure pipe.electric solenoid valve

For those who do not wear seatbelts friends

May look at me with contempt, may find the seat belt is a cumbersome, the department was uncomfortable, but this idea is really the "naive." We only have one, you should not put their own lives on their faith in good luck.seat belt adjuster
Current domestic traffic enforcement increasingly stringent, it is because more and more road traffic accidents are becoming a major social problems. Whether drunk driving or not wearing a seatbelt fine, or is to prohibit drivers from driving a cell phone, is the spirit of respect for human life as a starting point, do you have any reason to put themselves and the lives of others at the expense?
Develop a good driving habits are responsible for their own. In many countr ies, as long as the motor vehicle passengers must wear seat belts are, even if the back seat is the same, or do you really think that every seat belts are designed only for cars by checking it do?
Remind driving friends "not wearing a seatbelt a traffic accident mortality will increase fivefold, only one life, do not take their own lives and safety joke." Taobao search this "belt T-shirt", selling businesses is not much, but there are indeed recommended Taobao such products directly to the shelf when the contraband. Driving should major in school to strengthen education and training of qualified drivers.car safety seat belt

Through the material
Nylon screws, PC screws, PVDF screw, PP screw
Depending on the screw head
In accordance with the shape of the head can be divide d into: pan head plastic screws, countersunk head screws plastic, hexagonal plastic screws, hexagonal plastic screws, plastic, set screws, etc.
Slotted shape can be divided into: Phillips, slotted (slotted), hexagon, m word, plum, etc.
By Thread Size
Metric thread M2, M2.5, M3, M4, M5, M6, M8, M10, M12

Properly wear seat belts

So, how do we properly wear seat belts? China Automotive Technology and Research Center crash simulation laboratory director Zhang Xiaolong introduction, the proper use of seat belts can be divided into the following steps:fall protection equipment
First, we must adjust the sitting position. Ready, Stretch your hands, wrists just so hands on the steering wheel 9:00 and 3:00 nearly horizontal position, so that we can be effective in case of an emergency control of a vehicle; addition, the offer legs bent at 90 degrees, when the event of a crash, can ensure a sufficient buffer legs, hips and upper body to avoid injury.
Secondly, wear your seat belt. Slowly pull the shoulder belt to the waist, making it clos e to the body at the same time, try to ensure that straps across the chest, preferably over the shoulder 5 to 10cm, and close to the neck, while the waist is as below the abdomen. "Lower sub motorists need to put on a fixed point as low as possible, so as not reined in the neck, causing injury," Zhang Xiaolong special reminds us. Need extra attention, in our seat belt buckle into the lock button clicks, you should look at pulling the seat belt has been fastened to ensure that the belt buckle and undamaged.seat belt adjuster

The electric actuator is a kind of electric actuator as an energy source, according to the structure can be divided into the electric control valves, solenoid valves, pumps and electric motor speed regulator and accessorie s.3 way air valve
Electric control valve is the most common electric actuator, which by an electric actuator or a hydraulic actuator and a power adjustment means (control valve) components. Electric or electro-hydraulic actuator actuator controller output signal is converted linear displacement control valve or control valve shaft angular displacement. As part of their regulatory bodies, through single seat valve, double seat valves, angle valves, butterfly valves, ball valves, and so on.
Solenoid valve is a magnet of the electric power control unit for the two electrical actuators. Motor speed pump, by varying the speed of the pump motor, adjusting the flow rate of the pump electric actuator, usually with frequency converter supply to the changed frequency motor, the motor speed control of the input signal changes. With the throttle control valve for regulating the flow method, which has the advantages of energy saving, thus gradually applied. Electric power adjusting element and the electrical actuator control, such as the common induction regulator, thyristor regulator, etc., · By changing the current flowing through the load or the voltage applied to the load change in the load power control purposes. For example, a thyristor voltage regulator to control the heater, the temperature of the heater temperature is needed to meet the requirements.
(1) The electric actuator electric actuator motor and reduction gear for moving the valve actuator. Typically, the actuator input signal is a standard current or voltage signal, the output signal of the motor, reverse or stop the three switching signals. Electric actuators act quickly, fast response, the use of power access convenient, transmission distance and other characteristics.
The displacement of the actuator can be divided into straight trip, rotating multi-ring and other categories, according to the input sig nal and the output proportional, integral, and other types of relationships.stainless steel pneumatic cylinders
