Pneumatic principle flashboard valve:

Pneumatic valve is mainly made up of frame, gate, screw, nut and other parts, rotate the hand wheel so that the screw rod with ascrew nut and a gate reciprocating movement along the horizontal direction, to open or close the valve.

Fluid Couplings

1, the flapper valve shell test and seal test medium is water(preservative), other suitable liquid kerosene or viscosity of less than water.

2, the sealing is flashboard valve non-metallic sealing, sealing shell test and requirements prescribed by GB/T13927-92 D.

3, the sealing pair is a valve metal seal, the sealing requirement,the seat leakage by 1 * DNmm/s calculation, no sealing performance requirements do not do this test.

Insert plate valve 4, electric, hydraulic, pneumatic device to drive,the closed position setting, closed 3 times by 1 and 3 requirements of the shell and the seal test.

5, valve cleanliness requirements according to the provisions of JB/T7748.

6, static life test.

7, valve static life test times required, other technologies according to the provisions of JB/Z 234

The valve installation of High temperature gate

 High temperature gate valve is a gate opening and closing parts,RAM direction of motion perpendicular to the direction of the fluid,valve can only be fully open and fully closed, can not be adjusted and the throttle. There are two gate sealing surface, the most common mode of gate valve sealing surface to form two wedge,wedge angle varies with the valve parameters, usually 50, mediumis not high temperature is 2 ° 52'. Wedge gate valve can be made into a whole, called the rigid gate; also be made to produce small deformation of the gate, in order to improve its process, make up the sealing surface angle deviations arising during processing, thisgate is called the flexible gate.

Timing Belt Pulleys

The installation and use of

1 should be checked before installation the valve cavity and the sealing surface and other parts, there is dirt or sand does not allow attachment; 

2 the bolt joints, require even tighten; 

3 check the packing requirements of pressed parts, not only to ensure that the sealing filler, but also to ensure the gate open and flexible; the 

4 user valves in the former, the valve must be proof models,connection size and attention to media flow, to ensure consistencywith the requirements of the valve; 

5 the user to install the valve,valve driver must reserve the necessary space; connecting 

6 drivecircuit diagram shall be carried out; 

7 valve must be regularmaintenance, should not be a collision and extrusion, so as not to affect the seal.

     China pulleys manufacturer, produce: taper pulleys, adjustable pulleys, falt belts pulleys, china taper pulleys, sheaves, V-Belt Pullys for taper bushes, V-Belt Pullys with solid hub. 

    The exhaust valve is widely used in heating, water separator,radiators, floor heating. Cavitation is the release of the heating system and water supply pipes, suitable for application in harsh climate and environment of the North area.

Agricultural Chain

    Working principle

When the gas is generated in the system, because the gas density is low, along the pipeline to climb, finally gathered the highest point in the system. So the exhaust valve is generally installed in the highest point of the system. When the upper air into the exhaustvalve chamber gathered in the exhaust valve, with the increase of the gas in the valve, pressure rise, when the gas pressure is greater than the system pressure, the gas will decrease the water cavity, float together with the water level dropped, the exhaust port to open; gas drained, the water level rises, float will also rise, the exhaust port closed.

Installation

Application of quick exhaust valve pipeline in industrial medium iswater, as the rapid elimination of the gas pipeline equipment, to improve the efficiency and the protection of pipe water equipmentwithout deformation and fracture is essential equipment, pipeline.Valve is a cylindrical body, a total of internal main stainless steelfloating ball and plug. Installed at the outlet of pump Pu ordistribution line, to exclude a large number of air in pipe assembly,to enhance water pipe and pump efficiency, and once the pressureinside the pipe, the valve can be quickly inhaled air, in order to keep the line for the negative pressure generated damage.

Timing Belt Pulleys

1 quick exhaust valve must be installed vertically, which must ensure that its internal float is in the vertical state, so as not to affect the exhaust;

2 quick exhaust valve is installed, the best installed along with the cut off valve, so when you need to remove the exhaust valve repair,which can guarantee the system's closed, the water will not drain;

3 quick exhaust valve is usually installed at the highest point of the system, to improve the efficiency of the exhaust.

Stainless Steel Chain

    Installed at the outlet of pump Pu ordistribution line, to exclude a large number of air in pipe assembly,to enhance water pipe and pump efficiency, and once the pressureinside the pipe, the valve can be quickly inhaled air, in order to keep the line for the negative pressure generated damage.

     Generally adopt flange connection, the general pressure PN1.0-40/0.6-4.0MPa, 125Lb-300Lb/1.0-5.0MPa, diameter of DN25-400mm, the main material: HT250 grey cast iron, nodular cast ironQT450, /WCB steel, stainless steel / (CF8 (M), CF3 (M), etc.,suitable medium for water, suitable for urban construction (water),water conservancy, tube road. Quick exhaust valve body is cylindrical, including stainless steel floating ball valve parts, valve stem and valve. 

    The valve installed in the pump outlet or water distribution pipelines, to exclude a gathering in the air pipe, to improve efficiency in the use of pipelines and pump, when the pipeline once when the negative pressure, the valve quickly inhaled air, in order to prevent the pipeline from being damaged due tonegative pressure. 

     When the water began in the pipeline, the valveis in the open position, a lot of exhaust, when the air is exhausted,the valve is full of water, float up and drive the valve closed, to stop the exhaust tube, when the normal transportation, such as a small amount of air accumulation to a considerable extent on the valve,the valve in water fall, the air from the hole discharge. When the pump stops, the flow tube air or when the negative pressure tube,then plug the rapid opening, suction air, to ensure pipeline safety.
