Installation and Operation Tips for Chemical Gas Blind Flange Valves

Before installation, be sure to conduct a visual inspection. For valves with a working pressure exceeding 1.0 MPa and those capable of cutting off flow in the main pipeline, perform strength and tightness tests prior to installation; only after passing these tests are they permitted for use.

Blind flange valve

Manually operated blind flange valves are easy to operate, and most underground pipeline gate valves rely on manual opening and closing, making them cost-effective and highly competitive. However, their lack of brand recognition and numerous other unfavorable factors mean that this sizable gate valve market has yet to achieve true market maturity.

Safety Operating Requirements for Gas Blind Flange Valves

The setting of the electric power switch for the blind flange valve during actual operation should, as far as possible, prevent the valve from being left unattended. When personnel are operating the valve, they should stand in a favorable position and carefully monitor the surrounding environment for any changes.

Main functional parameters of the valve

A valve is a control component in pipeline fluid transport systems. It is used to alter the cross-sectional area of the flow path and change the direction of medium flow, performing functions such as guiding flow, shutting off flow, regulating flow, throttling, preventing backflow, diverting flow, or relieving pressure by overflow.

Checks to be performed before operating the electric blind plate valve

When the valve body is cast, its surface shall be smooth and flat, free from defects such as cracks, shrinkage cavities, sand holes, porosity, and burrs. When the valve body is forged externally, its surface shall be free from defects such as cracks, delamination, laps, and scars.

Valve Installation, Maintenance, and Operation

If installed in the wrong direction, it can affect performance and service life—for example, with a throttling valve—or render the valve completely ineffective—for example, with a pressure-reducing valve—or even pose a safety hazard—for example, with a check valve. In most cases, valves will have directional markings on their bodies; if no such markings are present, you should correctly identify the correct direction based on the valve’s operating principle.

The Enforcement Focus Shifts—“One Rise, One Fall”: How Can the Environmental Protection Reform Truly Deliver Results?

The stringent environmental regulations not only show no signs of easing up but are set to undergo a “fundamental” transformation—among which is the reform of the vertical management system for environmental protection agencies. On November 20, the Ministry of Ecology and Environment issued the "Notice on Coordinating and Promoting the Reform of the Vertical Management System for Monitoring, Supervision, and Enforcement of Ecological and Environmental Agencies Below the Provincial Level." While clearly outlining the timetable for implementing the vertical reform of environmental protection agencies, the notice once again underscores the redefinition of the relationship between "vertical" and "horizontal" authorities, with accountability serving as the central thread running through the reform. The vertical reform of environmental protection agencies has once again hit the "accelerator." Recently, the Ministry of Ecology and Environment released the "Notice on Coordinating and Promoting the Reform of the Vertical Management System for Monitoring, Supervision, and Enforcement of Ecological and Environmental Agencies Below the Provincial Level."

Renewable Energy Quota System and the Development and Prospects of Green Electricity Certificates

Renewable energy electricity boasts characteristics such as zero carbon emissions, cleanliness, environmental friendliness, and renewability. Developing renewable energy is an inevitable requirement for the global energy revolution and for green, low-carbon development. China has already pledged to the world that by 2020 and 2030, the share of non-fossil energy in primary energy consumption will reach 15% and 20%, respectively, and that carbon emissions will peak by 2030. Establishing a renewable energy quota system (hereinafter referred to as the “quota system”) and a green electricity certificate (hereinafter referred to as the “green certificate”) trading mechanism represents an important pathway for China to promote the development of renewable energy, drive reform of the energy system, and achieve its non-fossil energy consumption targets.
