As a drain device designed for thermal power plants, the pneumatic globe valve ZMQSY-1500LB plays an irreplaceable role in many key links of thermal power plants with its unique design and excellent performance. This article will introduce in detail the application scenarios, functional characteristics and improvement of the operating efficiency of ZMQSY-1500LB in thermal power plants.

I. Overview of ZMQSY-1500LB pneumatic globe valve

ZMQSY-1500LB is a Y-type pneumatic globe valve designed for high-temperature and high-pressure steam systems in thermal power plants. Its core function is to automatically remove condensate, air and other non-condensable gases in the steam system, while preventing steam leakage, thereby improving the thermal efficiency and operating stability of the steam system. The globe valve has the following characteristics:

High pressure tolerance: The design pressure level is 1500LB, which can adapt to the high-pressure steam environment of thermal power plants.

Fast response: It adopts pneumatic control, has a fast response speed, and can remove condensate in time.

High efficiency and energy saving: Reduce steam loss and improve thermal energy utilization.

Strong durability: Made of high-quality materials, high temperature and corrosion resistance, long service life.

II. Application scenarios of ZMQSY-1500LB in thermal power plants

1. Boiler system

The boiler is the core equipment of the thermal power plant, responsible for heating water into high-temperature and high-pressure steam. During the operation of the boiler, a large amount of condensed water will be generated in the steam pipe and heat exchanger. If the condensed water cannot be discharged in time, it will not only reduce the thermal efficiency of the steam, but also cause water hammer phenomenon and damage the pipes and equipment. ZMQSY-1500LB is installed at the steam outlet of the boiler and the low point of the pipeline, which can quickly remove the condensed water to ensure the dryness of the steam and the efficient operation of the boiler.

2. Steam turbine system

The steam turbine is a key equipment in the thermal power plant that converts steam thermal energy into mechanical energy. During the operation of the steam turbine, the condensed water in the steam will reduce the efficiency of the steam turbine and may even cause corrosion or damage to the blades. ZMQSY-1500LB is installed in the steam inlet and drain pipe of the steam turbine, which can effectively remove the condensed water to ensure the dryness of the steam and the safe operation of the steam turbine.

3. Heat exchanger system

The heat exchanger in a thermal power plant is used to transfer the heat energy of steam to water or other media. During the heat exchange process, the steam will gradually cool and form condensate. If the condensate cannot be discharged in time, the heat exchange efficiency will be reduced and energy consumption will increase. ZMQSY-1500LB is installed at the drain port of the heat exchanger, which can automatically discharge the condensate to ensure the efficient operation of the heat exchanger.

4. Steam pipeline system

The steam pipeline is an important channel for transporting steam in a thermal power plant. During long-distance transportation, the steam will gradually cool due to heat loss and form condensate. The accumulation of condensate in the pipeline will not only increase the flow resistance, but also may cause water hammer and damage the pipeline and equipment. ZMQSY-1500LB is installed at the low point and end of the steam pipeline, which can timely discharge condensate to ensure the smooth and safe operation of the steam pipeline.

5. Deaerator system

The deaerator is a device used to remove dissolved oxygen in the feed water in a thermal power plant. During the deaeration process, the steam will contact and cool with the feed water to form condensate. ZMQSY-1500LB is installed at the drain port of the deaerator, which can quickly remove condensed water to ensure the normal operation of the deaerator and the quality of water supply.

III. Functions and effects of ZMQSY-1500LB

1. Improve the thermal efficiency of the steam system

The condensed water in the steam system will absorb a lot of heat, reducing the dryness and thermal efficiency of the steam. ZMQSY-1500LB can remove condensed water in time to ensure the dryness and heat transfer efficiency of the steam, thereby improving the thermal efficiency of the entire steam system.

2. Prevent water hammer

The accumulation of condensed water in pipes and equipment may cause water hammer, generate huge impact force, and damage pipes and equipment. ZMQSY-1500LB can effectively prevent the occurrence of water hammer and protect equipment safety by quickly removing condensed water.

3. Reduce steam loss

Traditional globe valves may have steam leakage problems, resulting in energy waste. ZMQSY-1500LB adopts precise design and high-quality materials to effectively prevent steam leakage and reduce energy loss.

4. Extend the service life of equipment

Impurities and corrosive substances in condensate may cause corrosion to pipes and equipment. ZMQSY-1500LB can reduce the accumulation of corrosive substances in the equipment by timely draining condensate, thereby extending the service life of the equipment.

5. Improve the stability of system operation

The rapid response and efficient drainage capacity of ZMQSY-1500LB can ensure the stable operation of the steam system and avoid equipment failure and shutdown problems caused by condensate accumulation.

IV. ZMQSY-1500LB globe valve improves the operating efficiency of thermal power plants

1. Energy saving and consumption reduction

By efficiently draining condensate and preventing steam leakage, ZMQSY-1500LB globe valve can significantly reduce the energy consumption of thermal power plants and improve operating efficiency.

2. Reduce downtime

The stable operation of ZMQSY-1500LB can reduce equipment failure and downtime caused by condensate problems and improve the operating reliability of thermal power plants.

3. Reduce maintenance costs

The durability and easy maintainability of the ZMQSY-1500LB globe valve can reduce the equipment maintenance cost of the thermal power plant and extend the service life of the equipment.

The functions of the ZMQSY-1500LB pneumatic globe valve, which can efficiently drain water, prevent steam leakage and improve system stability, provide a strong guarantee for the safe and efficient operation of the thermal power plant.
