What is the pneumatic three-way ball valve, friends will be curious, then let us decorate the home network Xiaobian now to explain to everyone, what is the pneumatic three-way ball valve , the structural characteristics of the pneumatic three-way ball valve and its advantages What are the things that you will encounter in your life? What is the working principle of our pneumatic three-way ball valve, then everyone follows us to see the following article.
First, the advantages of pneumatic three-way ball valve
Pneumatic three-way flange ball valves are usually equipped with various accessories, such as solenoid valves, limit switches, positioners, etc., to achieve local control and long-distance centralized control, and the valve can be controlled in the control room without going to Manual control at the site or at high altitudes and in danger can save manpower, time and safety to a large extent.
Second, the structural characteristics of pneumatic three-way ball valve
1. Top-loading structure: The valve installed on the pipeline can be directly inspected and repaired online, which can effectively reduce the parking of the device and reduce the cost. This type of valve should generally be installed horizontally in the pipeline.
2. No friction and no friction: completely solves the problem that the traditional valve affects the sealing due to the mutual friction between the sealing surfaces.
3. Low-torque design: The valve stem with special structure design can be easily opened and closed with only a small handle.
4. Wedge seal structure: the valve is mechanically provided by the valve stem, and the ball wedge is pressed onto the valve seat to seal, so that the sealing performance of the valve is not affected by the pressure difference of the pipeline, and the sealing performance under various working conditions There is a reliable guarantee.
5, single valve seat design: eliminates the problem that the medium cavity medium of the valve affects the safety of use due to abnormal boosting.
6. Self-cleaning structure of the sealing surface: When the ball is tilted away from the valve seat, the fluid in the pipeline passes through the spherical sealing surface uniformly through 360°, which not only eliminates the high-speed fluid scouring on the valve seat, but also washes away the sealing surface. The accumulation of material reaches the purpose of self-cleaning.
Third, the working principle of pneumatic three-way ball valve
1. Pneumatic three-way ball valve is a three-channel rotary ball valve used for medium shunting, confluence and flow direction switching. Any one pipe can be used as an inlet or an outlet. The pneumatic three-way ball valve is divided into two types: a pneumatic three-way L-type ball valve and a pneumatic three-way T-type ball valve, which can meet different production process requirements. The pneumatic three-way L-type ball valve cuts off two of the three pipes, and the pneumatic three-way T-type ball valve realizes the joining and splitting of the three connecting pipes.
2. Pneumatic three-way ball valve is matched with electric valve positioner. It can control the operation by inputting 4~20mADC signal and 0.4~0.7MPa air source to realize the adjustment of pressure, flow, temperature and liquid level. It is also equipped with a travel limit switch, solenoid valve, pressure reducing valve and 0.4-0.7MPa air source to realize the switching operation, and send out two pairs of passive contact signal indicating valve switches.
What is the so-called pneumatic three-way ball valve? Friends have already understood in our article, then what are the advantages of this pneumatic three-way ball valve, and the structure of the pneumatic three-way ball valve, we also know the pneumatic The benefits of the three-way ball valve working principle, then what are the needs of everyone, you can pay attention to our decoration home network.
