Micro exhaust valve performance and features

Micro exhaust valve performance and features: 1, micro exhaust valve Under normal circumstances, the water contains about 2VOL% of the dissolved air, the water process, the air from the water continue to release, gathered in the pipeline at the high point , The formation of air bags (AIRPOCKET), making it difficult to water, the system can reduce water transport capacity of about 5-15%. The main function of this micro exhaust valve is to eliminate the 2VOL% of dissolved air and is suitable for installation in high-rise buildings and pipelines in the plant area. The small pump station is used to protect or improve the system's water delivery efficiency and save energy. 2, single-rod micro trace exhaust valve, an oval-shaped body similar to all internal components, including float, lever, valve seat, etc. are 304 stainless steel, internal standard exhaust aperture 1/6 ", suitable for PN16 working pressure environment Medium temperature: 0-80 ℃ 3, the micro exhaust valve is mainly used in HVAC systems, often installed in the commanding heights or elbows and other places to eliminate excess gas pipeline to improve the use of pipe efficiency and reduce Dielectric temperature: 0-80 ℃. The role of trace exhaust valve principle: 1, trace exhaust valve for the highest point of the pipeline or elbow or a place to close the gas to exclude the gas pipe to clear the pipeline, To achieve normal work.If not installed this valve, gas pipe at any time appear resistance, so that the water pipe capacity does not meet the design requirements, and secondly, when the pipeline power outage, stop pumping pipe in time a negative pressure can cause pipe vibration or rupture. Row, the intake valve quickly inhaled air pipe, to prevent vibration or rupture of the pipe. 2, when the water into the pipe, stop the stopper in the lower part of the positioning, a lot of exhaust, when the air row is exhausted, the water Into the valve to float the ball, the transmission plug to close, stop the exhaust pipe in normal operation will naturally produce a small amount of gas, these gases will gather to the upper part of the tube to a considerable extent, the valve water level drops, the float down the water down gas Outlet from the hole, such as power outages, stop the pump, the pipe will be negative pressure when the air flow empty, float down the water, open the hole for a large number of intake pipe to ensure safety.

Hitachi Launches New TX Series Escalator for

India, Asia and the Middle East

Hitachi Escalator Parts

Tokyo, August 21, 2017 --- Hitachi, Ltd. (TSE: 6501, [Hitachi") and Hitachi Building Systems Co., Ltd. today announced the launch of the new TX Series escalator for India, Asia and the Middle East. The escalator has already been released in China*1, and will be released in stages across the remainder regions, commencing August 21, 2017.

In July 2016, Hitachi integrated its escalator businesses of Japan and China, consolidating its resources and enhancing its business operations in both countries, centered around its key business location in Guangzhou, China. The new TX Series escalator launched by Hitachi is a model that meets multiple standards in China, India, Asia and the Middle East. The model follows the same concept for the machine room-less elevator for Asia and the Middle East which was launched in September 2016. In addition to conforming to Chinese safety and quality standards for escalator equipment, the TX Series will be manufactured in accordance with Hitachi's own strict standards of safety and quality, adhering to safety standards in all other regions. It also adopts a functional design based on the concept of an escalator that fits closely with the unconscious actions of users, in the pursuit of their ease and comfort.

The TX Series offers flexibility with a selection of various product specifications, as well as its excellent design and safety features, designed to cater to a diverse range of customer needs. It also saves space required for the installation, covering a smaller area in comparison with existing products*2.

Hitachi will begin sales of the TX Series in Thailand, followed by launches in the Philippines, Malaysia and various other regions, and aims to receive orders of 10,000 units in 2018 in China, India, Asia and the Middle East.

Features of the TX Series

  1. Safety
    The TX Series offers various new safety features designed with optimal user safety in mind. The side portions of the steps are 8 mm higher than the central portion to prevent accidents in which a users' shoe can become caught between the step and the skirt (side wall) of the escalator. The new TX series has also been fitted with brushes located at foot level on the left and right skirts to let users know if their foot comes into contact with the side walls. A special finish has also been adopted for the landing plates at the entry and exit points of the escalator to prevent users from slipping when getting on and off the escalator.
  2. Design
    The TX Series adopts a simple and functional design that offers the smoothness, safety and comfort that users unconsciously expect to experience when riding an escalator. For example, by minimizing the size of the metal frame supporting the escalator's balustrades, the TX Series' design maximizes the size of the glass surfaces, and achieves greater simplicity at the entrance and exit points (landings) by reducing the number of recesses and protrusions around the hand rail. Additionally, by expanding the installation space of the light fixture, the TX Series also enables enhanced lighting options for illuminating the entire surroundings of the balustrades.
  3. Space saving
    By shortening the span dimensions*3 by 150 mm, the TX Series has made it possible to install escalators in more confined spaces where installation presents difficulties with conventional product designs.
*1 In China, Hitachi started selling the TX Series escalator in June, 2017.

*2 The made-in-China escalator, [SX series," which is previous model of [TX series."

*3 The span between the beam on upper floor and that on the lower floor of the escalator when the escalator is installed.
