Dynamic seal mainly refers to the valve stem sealDynamic seal mainly refers to the valve stem seal. Polytetrafluoroethylene braided packing: woven thin PTFE tape into packing, which has excellent corrosion resistance and can be used in cryogenic media. For example, in terms of compression bolts, it can be divided into T-bolts (used for low pressure valves with a pres...2020.11.04 02:16ptfexl.com
The sealing performance is worse than that of ball valves and globe valvesGate valve: A gate valve is a valve whose closing member (gate) moves along the vertical direction of the channel axis. The sealing performance is worse than that of ball valves and globe valves, so it is used in places where the sealing requirements are not very high. The ball valve is mainly used for cutting off, dis...2020.10.22 02:12ptfexl.com
The pressure and speed have the same relationship as the moldThe mold temperature and the length of the cooling time affect the sticking of the finished product, shrinkage, dimensional tolerance, surface brightness, cycle, etc. The cycle is long and the screw will not retreat. Its function makes the raw material more compact in the transportation and compression. The pressure an...2020.10.14 06:26ptfexl.com
Every time the production line needs to be shut down for maintenanceAt the beginning of its investment, pollution control was the top priority. The test results showed that the strength and air permeability of the filter bag were still good after 4 years of use, and its strength was around 300 psi. Reduce user maintenance and operating costs in many ways. The company has advanced equip...2020.09.16 03:12ptfexl.com
The varnished cloth composited with PTFE coatingThese applications all use the low friction coefficient and non-stick characteristics of the PTFE material, which shows that the tension of the product is reduced to the lowest when the product passes, and the attached dirt is also easy to clean. In addition, if the PTFE material is applied to rollers PTFE coated adhes...2020.08.18 05:39ptfexl.com
