PVC Self-Repair High Speed Zipper Door
Zipper quick door
The curtain of the high-speed zipper door is made of 1.2MM PVC coating cloth which can be embedded into the window. The unique design of this zipper door makes it possible to provide efficient goods entrance and exit under the premise of minimizing heat loss, so as to maintain the original temperature conditions in the room. The high-speed zipper door can provide different opening and closing speeds. According to the different needs of customers to provide the best speed of adaptation. The high speed zipper door curtain section ensures the safety of equipment and personnel without any solid parts. The high speed zipper door has a self-repair function, which means that even if the curtain is derailed in the middle (e.g., hit by a forklift), The self-healing system will automatically guide the curtain rerail in the next loop.) We can do this in the event that the front or back of the door hits the curtain and derails.
The new zipper is professional for derailed repair zipper door, zipper head material nylon 66, with built-in steel wire rope and screws fixed curtain, under the impact of gravity can let the curtain out of the rapid and correct return to the track, and track teeth without damage, durable, improve the original zipper teeth easy to wear defects.

Gas cylinders store high-pressure gas, but for applications like welding and cutting, the pressure must be reduced to a safe and usable level. This is where a pressure reducer comes into play. It ensures that the gas is released at a stable and controlled pressure, making it safe and efficient for use. In short, a pressure reducer is a device that lowers high-pressure gas to a lower, more manageable pressure while maintaining consistent output flow and stability.

Product Details Introduction
1) This regulator is ideal for industrial manufacturing, construction, and installation projects.
2) The dual-gauge design allows for easy monitoring of both cylinder pressure and operating pressure.
3) The main body is made from high-quality brass, while the upper cover is crafted from aluminum alloy with a spray finish. A 60mm pressure gauge is included, along with an external relief valve and a sintered bronze filter at the air inlet.
Different Types and Models of Pressure Regulators
1) The SJ7-1O pressure reducer has a brass body. Its two-stage pressure relief system includes components such as a valve jack, pressure regulating spring, elastic membrane device, and pressure relief door. The first stage reduces the high-pressure gas to medium pressure (around 2 MPa), which then enters the second stage for further reduction.
In the second stage, adjusting the pressure regulating screw controls how much the pressure reducing valve opens or closes, using the pressure spring, elastic membrane assembly, and valve jack rod. This helps regulate the oxygen supply from the first stage or stop it entirely.
2) The QD-1 type pressure reducer has an inlet joint thread size of 315.875mm, an inner diameter of 5.5mm, and an outlet inner diameter of 6mm. It can handle a flow rate of 80m³/h. It also features a high-pressure oxygen gauge (range: 0–25MPa) and a low-pressure oxygen gauge (range: 0–4MPa).
When the QD-1 decompressor is used, turning the adjusting screw clockwise opens the decompression valve, allowing high-pressure oxygen to flow into the low-pressure chamber. As the oxygen expands in this chamber, the pressure decreases, completing the decompression process.
3) The SJ7-10 double-stage pressure reducer has an inlet joint nut thread size of G1/5.875mm, with a joint diameter of 7mm. The outlet joint diameter can be selected based on specific needs—either 5mm or 9mm. The high-pressure gauge range is 0–25MPa, and the low-pressure gauge range is 0–4MPa.
