Pressure Reducing and Desuperheating Station

Product Introduction

Pressure reducing and desuperheating station is in the modern industrial cogeneration and district heating (or steam) and light industry, electric power, chemical, textile, and other enterprises are widely used in thermal engineering of a steam heat parameters (pressure, temperature) to change device and use of waste heat energy saving device, through this device, the steam parameters provided by the user to the user needs to the appropriate temperature and pressure,In order to meet the requirements of users, and can fully save heat energy, reasonable use of heat energy.

Product Advantage

1. Adopts the structure of temperature reducing and pressure reducing valve, so that the temperature reducing and pressure reducing of steam are carried out in the same valve, so that the length of the whole device is greatly shortened, the area of occupation is reduced, and the project investment is reduced.

2. Adopts straight stroke double valve seat temperature reducing and pressure reducing valve structure, the valve is equipped with a netting cover to enhance the atomization effect of water reducing, protect the valve seat and valve body, prolong the service life of the valve, and also reduce the noise of the device.Double - seat valve unbalance force small, wide range of regulation, smooth action, must not appear stuck phenomenon.

3. The temperature regulating system adopts the straight stroke single seat water supply regulating valve + throttling device, which can reduce the leakage of the valve and reasonably distribute the pressure difference on the water supply system. The same caliber, different flow coefficient Cv value can be selected, which greatly improves the sensitivity and accuracy of the temperature regulating system.

4. Direct stroke electric actuator is used for electric temperature reducing and pressure reducing valve and electric water supply regulating valve, which eliminates the traditional lever hinge mechanism, reduces the empty stroke link, and further improves the sensitivity and accuracy of the regulating system.

Product Structure

pressure reducing and desuperheating station is composed of a control system, a pressure reducer system, a water-jet temperature reducer system and a safety protection system.Its characteristics are as follows:

One-piece desuperheating decompression is the main structure of the steam, feed water regulator and the temperature and pressure-releasing valve safety device, steam to reduce temperature and pressure relief finish, in the same valve structure on a short length compared with split type, used in a steam pressure 2.5 MPa/temperature above 400 ℃ parameters, under the condition of the steam pressure and temperature, steam flow rate is also high,At this time, the use effect of temperature reducing and pressure reducing valve is better, and the adjustable ratio is 30~100%.Our company produces the one-piece desuperheating decompression device matching to the two-seater balance type structure, the temperature and pressure-releasing valve leakage is slightly larger, as Ⅱ level (highest level Ⅲ), when a steam temperature above 425 ℃, 20 steel export steam pipeline can be directly (carbon steel), and not as fission type structure, because of time temperature did not cut down,As a result, the steam pipe has to use alloy steel, increasing the cost.When the primary steam pressure temperature is below 2.5Mpa /400℃, the corresponding steam flow rate is also low, and the temperature reduction and decompression effect is not as ideal as the split type. Therefore, when the primary steam pressure temperature is above 2.5Mpa /400℃, the integrated temperature reduction and decompression device is mainly recommended.

Company Advantage

The company has a perfect quality management system, has passed ISO9001 quality management certification. In 2010, it obtained the special equipment manufacturing license of the people's Republic of China issued by the General Administration of quality supervision, inspection and Quarantine of the people's Republic of China, including pressure regulating valve (grade A1), temperature and pressure reducing device (Grade B), ball valve, butterfly valve (grade B1), gate valve, globe valve and check valve (grade A2).
