Overview

The control part of the coal mine underground dedicated valve adopts advanced integrated modules, which can achieve opening, closing, and adjustment of the valve through three control methods: remote control, on-site control, and bus type centralized control. It has the characteristics of advanced control principles, comprehensive functions, long-term stability and reliability, high integration, low heat generation, easy loading and unloading, and simple maintenance. It is widely used as a switch regulating device for connecting or cutting off the medium in oil and steam pipelines in petrochemical and thermal power plants.

Product Details

One,MASpecial valves for underground coal minesMining explosion-proof integrated electric gate valveStructural features:

1. The valve has low fluid resistance. Due to the straight through valve body of the gate valve, the flow direction of the medium does not change, so the flow resistance is smaller compared to other valves.

2. The sealing performance is better than that of a globe valve, and the opening and closing are also easier than that of a globe valve.

3. Widely applicable, in addition to steam, oil and other media, it is also suitable for media containing granular solids and high viscosity, as well as for use as vent valves and valves in low vacuum systems.

4. Gate valves are dual flow valves that are not restricted by the flow direction of the medium, making them suitable for pipelines where the flow direction of the medium may change, and also easy to install.

Secondly,MASpecial valves for underground coal minesPrinciples for selecting explosion-proof integrated electric gate valves for mining:

1. Requirements for valve fluid characteristics. Gate valves are selected for working conditions with low flow resistance, strong flow capacity, good flow characteristics, and strict sealing requirements.

2. High temperature and high-pressure media. Such as high-pressure steam, high-temperature and high-pressure oil products.

3. Low temperature (cryogenic) medium. Such as liquid ammonia, liquid hydrogen, liquid oxygen and other media.

4. Low pressure large caliber. Such as water supply projects and sewage treatment projects.

5. Installation position: When the installation height is limited, use a concealed stem wedge gate valve; When the height is not limited by Zou, choose a rising stem wedge gate valve.

6. Wedge gate valves can only be used for fully open or fully closed applications and cannot be used for regulating or throttling purposes.

3、 The basic functions of the intelligent explosion-proof flange rising stem electric gate valve for mining are:

(1) Equipped with an embedded microprocessor. Embedded microprocessors are the foundation of intelligence, enabling devices to have the most basic intelligence capabilities.

(2) Human computer interaction interface. Only through the human-machine interface can operators communicate with the equipment and transmit the required working methods to the equipment, which is the external form of basic intelligence.

(3) Data recording. Operators can query past work situations and fault states.

(4) On site configuration and fault self diagnosis. It can achieve fault self checking and on-site configuration, enabling intelligent electrical equipment to adapt to various on-site requirements, output various signals, and provide more complete feedback on equipment working conditions.

(5) Digital communication interface. Provide development space for the level of intelligence and networking.
