Ductile Iron Ball Check Valve SWD-M04

Ball check valve Structure :
The ball check valve has a simple structure and is mainly composed of a spherical device and a valve body. The spherical device is composed of a ball cover and a rubber ball. The rubber ball is processed into a core by a steel plate and is covered with a rubber layer to maintain a certain elasticity and sufficient strength.
The working principle is that the rubber ball is rolled in a short stroke in the dome to realize the opening and closing of the valve. When the water pump starts, the pressure of the water breaks the rubber ball, so that the rubber ball rolls to the right side, and the check valve opens; after stopping the pump, the rubber ball is forced to roll to the left side due to the backwater pressure of the system, and the check is stopped.
The rubber ball is made of hollow steel ball, and the rubber with good elasticity is used to ensure the sealing and to reduce the damage to the pipeline system during the valve closing process. The tapered cone with a hole fixes the steel ball when the valve is opened and eliminates the pressure of the contact area between the rubber ball and the tapered body so that the contact is in surface contact, and the hydraulic loss caused by the chattering of the rubber ball in the valve body is reduced.

Nice post. I learn something more challenging on different blogs everyday. It will always be stimulating to read content from other writers and practice a little something from their store. I’d prefer to use some with the content on my blog whether you don’t mind. Natually I’ll give you a link on your web blog. Thanks for sharing.
Today, I went to the beach with my kids. I found a sea shell and gave it to my 4 year old daughter and said “You can hear the ocean if you put this to your ear.” She placed the shell to her ear and screamed. There was a hermit crab inside and it pinched her ear. She never wants to go back! LoL I know this is entirely off topic but I had to tell someone!

Howdy! I know this is kinda off topic nevertheless I’d figured I’d ask. Would you be interested in trading links or maybe guest authoring a blog article or vice-versa? My site goes over a lot of the same subjects as yours and I feel we could greatly benefit from each other. If you’re interested feel free to send me an e-mail. I look forward to hearing from you! Fantastic blog by the way!

Have you ever thought about adding a little bit more than just your articles? I mean, what you say is valuable and everything. Nevertheless think of if you added some great pictures or video clips to give your posts more, “pop”! Your content is excellent but with images and clips, this website could certainly be one of the best in its niche. Superb blog!
