Corrosion-Resistant Acid And Alkali-Resistant Cast Steel Pipeline Purging Valve
Features
After the installation of the purging process pipe system, air purging or steam purging can be used according to the service conditions of the working medium and the dirt degree of the internal surface of the pipe. The large compressor of the production unit or the large container in the unit can be used for intermittent air purging. The purging pressure shall not exceed the design pressure of vessels and pipelines, and the flow rate shall not be less than 20m/s. The steam purging shall be carried out with large flow of steam, and the flow rate shall not be less than 30m/s.
Characteristics:
1. Wedge gate is adopted for the valve, and the gate plate and valve body guide device are welded with hard alloy to ensure that the valve can be opened frequently and smoothly.
2. The sealing surfaces of free cakes and valve seats are made of the latest surfacing materials, which have strong wear resistance and scratch resistance.
3. The electric valve rod adopts double head or three head threads to ensure the quick operating of valve.

Bypass Valve
Features:
1. The valve is analyzed by finite element method, and the wall thickness is uniform to prevent excessive stress caused by temperature change.
2. The valve body is forged and welded, with reliable quality, and can withstand and absorb the pressure and vibration from the pipeline.
3. Unbalanced multi hole cage type wide core, two-stage synchronous adjustable decompression, low voice, good adjustability and wide adjustment range.
4. Adjust the internal spray water to reduce the temperature. The spray hole of the atomizing nozzle changes synchronously with the load. The atomizing effect is good without water hammer.
5. Double guide, welded wide rod core connection and reasonable fit clearance at high temperature make the operation stable and vibration free.
6. The sealing surface of the wide seat is welded with hard alloy, and the surface of the wide rod and the throttling internals are sprayed with hard alloy, so the service life is long.
7. One flat seat, reliable cone sealing, self cleaning and less leakage.
Characteristics:
The valve is light, compact in structure and convenient for maintenance. It is used in the turbine bypass system to improve the efficiency of the power plant and eliminate steam loss.
The medium and high pressure bypass can be started, closed and operated in an orderly manner within the set load range, can control faults, and can be switched to operating conditions under different working conditions. The low pressure bypass is characterized by extremely compact structure, fast response, low vibration and low noise, point to realize steam regulation.

Drain Valve
Features:
The valve core is an important part of the control valve. In addition to the excellent material performance, the structure is the key to the valve. We uses the anti scour protective cover structure in the design to avoid the direct scouring of the sealing surface of each internal part by the medium flow, which effectively improves the service life of the valve. The shell is made of silver, with smooth appearance and uniform organization, meeting the requirements of high temperature and high pressure. The sealing materials are specially matched to ensure high hardness and reasonable hardness difference of the sealing surface. Precise grinding, smooth as a mirror, effectively increase the tightness of the valve seal and extend the service life.
