Sewage suction trucks are sanitation vehicles that collect, transfer, and transport sludge, sewage, etc. Sewage suction vehicles are more powerful than suction trucks and have a wider range of applications. Its fast working speed, convenient transportation, large capacity, and transport medium involve the characteristics of most liquid substances such as excrement, mud, crude oil, etc., and are loved by many environmental protection companies and sanitation. The sewage suction trucks on the market today are equipped with powerful vacuum pumps. They have a large suction force and a long suction range. They are suitable for the suction and shipment of sludge in sewers. They are also very useful for mud, gravel, bricks and other debris in sewers. Good results. The main purpose of a sewage suction truck is to dredge sediments and dead mud in urban sewers, pipelines, and also to clean pipeline walls. The purpose of a sewage suction truck is not unique. Sometimes it can also be used as a sprinkler. It can also be used as a fire truck in an emergency. The sewage suction truck works by using the principle of atmospheric pressure to pump sewage. Place the suction pipe of the suction truck on the liquid surface, and use a suction pump to suck the air in the tank clean. Then the pressure in the tank is much lower than the atmospheric pressure. Sewage under the influence of atmospheric pressure, through the sewage pipe into the pipe. The fouling principle is similar to that of suction. The air is pumped by a suction pump into a tank. The pressure in the tank is greater than the atmospheric pressure. The sewage in the tank enters the sewage discharge pipe under the pressure of the tank and is excluded from the tank. Sewage suction vehicles have high suction efficiency, self-priming, self-discharging, direct irrigation, long service life, high working speed, convenient transportation and simple operation. When choosing a sewage suction truck , pay attention to the quality of the tank and the degree of sealing. If you do not pay attention to the above problems, it will lead to deformation of the tank. The selection of accessories such as suction pumps should pay attention to the ability to withstand pressure and the perception of temperature differences. In addition, China has already enforced the country's three standards for the discharge standards of sewage trucks. The friend who is ready to buy a car should pay attention to the purchase of the cleaner vehicle manufacturer. The above is a brief introduction to Xiao Bian's use of sewage suction trucks, working principles, and selection criteria. If you still have problems, you can contact our staff. (Wen/Jun Xun)
Butterfly Valve is from a family of quarter-turn valves. Butterfly valve is typically used to regulate a fluid flowing through a section of pipe. A flat circular plate is positioned in the center of the pipe. The plate has a shaft through it connected to an actuator on the outside of the valve. Rotating the actuator turns the plate either parallel or perpendicular to the flow. Unlike a Ball Valve, the plate is always present within the flow, therefore a pressure drop is always induced in the flow regardless of valve position.
There are different kinds of butterfly valves, each adapted for different pressures and different usage.
Butterfly valves are relatively easy to maintain. The resilient seat is held in place by mechanical means, and neither bonding nor cementing is necessary, Because the seat is replaceable, the valve seat does not require lapping, grinding, or machine work.
Butterfly valve is also a type of flow control device, used to make regulating fluid flowing through a section of pipe.

Wafer Butterfly Valve
High Performance Butterfly Valve
Pneumatic Butterfly Valve
The resilient butterfly valve, which uses the flexibility of rubber, has the lowest pressure rating.
The high performance butterfly valve, used in slightly higher-pressure systems, features a slight offset in the way the disc is positioned, which increases the valve's sealing ability and decreases its tendency to wear.
The valve best suited for high-pressure systems is the Triple Eccentric Butterfly Valve, which makes use of a metal seat, and is therefore able to withstand a greater amount of pressure.
