How to determine the quality of a speed gate swing gate?

The speed-passing gate swing gate is also considered as a kind of pedestrian passage gate in the practical life application. Although the speed-passing gate swing gate is beautiful and beautiful, the traffic speed is also fast, but when purchasing the speed-pass gate swing gate Our procurement staff still needs to know some questions, the choice of speed gate swing gate:
1. From the material point of view: the speed-passing gate swing gate is used for pedestrian traffic management, and the long-term operation and anti-collision capability of the gate should be considered in various places. Therefore, it is necessary to use 304 stainless steel material. of. The door panels are made of soft materials. When people enter the gates, they may hit the gates. All soft materials will not cause scratches.
2, the bar code reader above the card reader window selection, most manufacturers still use acrylic material. Acrylic material is convenient and low in cost; easy to process and install, but after many times of brushing, acrylic will wear rough, affecting the reading speed and accuracy of the barcode, and will also affect the appearance of the appearance. Therefore, the research and use of wear-resistant quartz glass; not tight appearance looks good; and wear-resistant super strong!
3. Ticket inspection speed: In the case of large traffic flow, the speed of ticket inspection is a very important indicator. For example: at a subway station, at a scenic spot or at a bus stop. The traffic volume of these places is relatively large, and if the ticket inspection speed is not fast enough, it will affect the management efficiency of the entire site. The ticket inspection speed depends on the control mode on the gate, and the research and development gate uses a military-grade encoder to control the mechanical movement speed. Generally, the gate response speed is within 300ms.
4. Fault-free operation life: The speed-passing gate swing is driven by the motor, and the life of the Zhonghao motor will not be less than 8 million times.

Valve Part

Valve part is kind of pipeline fittings, which is used to open and close, control, adjust and control the flow of medium parameters (temperature, pressure and flow). According to its function, it can be divided into the cut-off valve, check valve, regulating valve, etc.
Valve is the control unit in fluid conveying system, having function of cut-off, regulation, guide, to prevent the reverse flow, voltage regulator, the leakage of the shunt or overflow and so on. Valve parts used in fluid flow control system, have quite a wide varieties and specifications, from the most simple cut-off valve to all kinds of valves used in extremely complex automatic control system.
The valve can be used to control air, water, steam, all kinds of corrosive medium, mud, oil, liquid metal and radioactive medium. According to the material, valve part is divided into iron valves, cast steel valves, stainless steel valves (201, 304, 316, etc.), chrome molybdenum steel valves, molybdenum chrome vanadium steel valve, dual phase steel valves, plastic valves, non-standard custom-made valves, etc.
