Saguar valve installation axial space is too large

图片名称

Hello: First of all, thank you for using our coaxial valve. We now have the latest thin -type coaxial valve. The axial length of this valve is almost the same as that of the ball valve. I don't know how large you are using on the spot? If you have any need, please contact us!

Diagnosis and maintenance of air fluid supercharged pump

图片名称

Administrator reply: Diagnosis and maintenance: 1. When the pressure pump suddenly stops working, check the control voltage signal first. If the signal is normal, turn off the gas source to ensure that there is no compressed air in the pump, the limited valve nut on the right end cover is opened, and the limit position is taken out. Valve stems, check whether the sealing ring leaves the groove. If you leave, push it back to the groove, reinstall the nut, and connect the gas source; if the pump is still not moved, then turn off the gas source to ensure that there is no compression in the pump compression. When air, replace the electromagnetic direction valve and connect the gas source; if the booster pump is still not working, please contact us or the nearby agent or supplier. 2. When the output pressure of the pressure pump decreases or does not reach the set pressure, please check whether there is a leakage of the pipeline. If there is no leakage, please check whether the pressure of the gas source is normal. If everything is normal, consider replacing the sealing parts.

Precautions for installation

图片名称

1. Before installation, pay attention to the conditions of the valve, such as the operating pressure range, power supply conditions (communication, DC, voltage), function, diameter, etc. comparative inspections are compliant with the valve standard or instructions. 2. Before installation, ventilation and power -on test should be performed on the test table to check whether the directional performance of the valve is normal. 3. Before installation, it should completely remove rust, dust and other dirt in the pipeline. 4. When installing, pay attention to the installation position of the valve and the direction of the airflow indicated. In the upper reaches of the valve gas source, the water divide filtrate, pressure reduction valve and oil mist lubrication must be installed to ensure that the supply valve has a certain pressure of dryness, clean, and lubricating air to work normally and reliable.

What are the performance of the valve?

图片名称

Sealing performance The capacity of the sealing parts of the valve prevent the medium from leaking, which is the most important technical performance indicator of the valve. There are three seals: the connection between the valve body and the valve cover; the matching and the placement of the filler and the valve stem and the filling letter; The leakage of the last place is called internal leakage, which is usually not strict with what we call. It will affect the ability of the valve to cut off the medium. For cut -off valve categories, internal leakage is not allowed. The leakage of the first two places is called the outer leak, that is, the liquid medium is leaked from the valve to the outside of the valve. External leaks will not only cause material losses, but also pollute the environment, and cause accidents in severe cases. For flammable and explosive, toxic or radiation medium, leakage cannot be allowed. Such valves must have strict and reliable sealing performance.
