Manual Plug Valve

 Manual plug valve, also known as manual knife-type gate valve, knife-shaped gate valve is a kind of valve that the gate and the valve seat are always in close contact and seal. The principle is that the gate board has a diameter-sized round opening and is opened by the gate. Closing makes the round port on the ram plate completely separate from and coincide with the diameter. Manual plug-in valve is the main control equipment, widely used in metallurgy, mining, building materials, food. Manual plug-in valve The manual plug-in valve is a kind of powder, granular material, granular material and small material flow rate or delivery volume used in supporting the unloader. The diameter of the manual screw gate is matched with the feed inlet of the unloader. There are two kinds of square and round.

 

Features

Manual plug-in valves are often used in conjunction with unloading devices or silos. The manual spiral gate valves are flange-connected for easy installation. There are two types of inlet and outlet ports, square and round. There are dozens of specifications depending on the size of the caliber. Metallurgy, carbon, chemicals, building materials and other industries. The manual plug-in valve, belonging to the ash valve has the advantages of simple and compact structure, reasonable design, reliable sealing, light and flexible operation, small size, smooth passage, small resistance, easy installation, and easy disassembly. The manual screw gate valve can be installed horizontally or vertically, and has wear-resistance. Features such as automatic compensation and long life. Manually inserting the valve in the normal use of the various transmission parts should be regularly checked, add lubricant to maintain

 

Installation and instructions

1. Check the inside of the valve chamber and the sealing surface before installing the plug valve, and do not allow any dirt or sand particles to adhere;

 

2. The bolts at each connection must be tightened evenly;

 

3. Inspect the packing area for compaction, which not only guarantees the sealability of the packing, but also guarantees that the gate plate can be opened flexibly;

 

4. Before installing the valve, the user must check the valve model, connection size and pay attention to the flow of the medium to ensure consistency with the valve requirements;

 

5. The user must reserve the necessary space for valve actuation when installing the valve;

 

6. The wiring of the drive device must be in accordance with the wiring diagram;

 

7. The flapper valve must be maintained regularly and must not be crushed and squeezed to avoid affecting the seal.

The Electromagnetic Valve 2019

Electromagnetic pulse valves (also known as diaphragm valves) are compressed air "switches" for pulse bag filter dust cleaning systems. By the control of the output signal of the pulse jet control instrument, the filter bag is cleaned by one row (chamber), so that the resistance of the filter is kept within the set range, so as to ensure the processing capacity and dust collection efficiency of the filter. DMF-Z electromagnetic pulse valve  is a right-angle valve, and the angle between the inlet and outlet is 90 degrees, which is suitable for the installation connection between the airbag and the dust blower tube. The air flow is unobstructed and it can provide the required clear air pulse. DMF-ZM electromagnetic pulse valve is the same as the "Z" series of the right-angle valve, suitable for airbag and dust collector spray pipe installation connection, the import and export of the two ends with a fixed nut for installation so that installation and us

Electrostatic Dust Precipitator

  1. Introduction of electrostatic dust precipitators   The power supply of the electrostatic precipitator consists of a control box, a step-up transformer and a rectifier. The output voltage of the power supply also has a great influence on the dust removal efficiency. Therefore, the operating voltage of the electrostatic precipitator must be maintained at 40-75kV or even above 100kV.   2. Basic structure of electrostatic dust precipitators   The electrostatic dust precipitators  are composed of two parts: one part is the main system of the electrostatic precipitator; the other part is the power supply device that provides high-voltage direct current and the low-voltage automatic control system. The high-voltage power supply system supplies power to the step-up transformer, and the dust collector of the dust collector is grounded. The low voltage electric control system is used to control the temperature of the electromagnetic vibrating hammer, the ash discharging electrode, the ash c

Ash Discharge Valve

The opening and closing part of the ash discharge valve  electric plug valve is a gate plate, and the direction of movement of the gate plate is perpendicular to the direction of the fluid. The electric plug valve can only be fully opened and fully closed and cannot be adjusted or throttled. The gate has two sealing surfaces. The two sealing surfaces of the most commonly used mode gate valves form a wedge, and the wedge angle varies with the valve parameters. Principle: There is a round opening of a diameter on the gate, and the opening and closing of the gate makes the round opening on the gate to completely separate from and match with the diameter. Electric three-way valves are used for air conditioning, thermal ventilation, heat treatment in heat treatment plants, and industrial fluid control. Air-conditioning, heating, ventilation, domestic hot water and other civil systems and chemical, petroleum and metallurgical and fluid automation. Our dust collection syste
