Trigger, lock flap, seal ring, spring, shift fork, valve seat, rotary plunger, control ring, slider, collar, bottle seal, spool tube, water separation, sealing ring, sealing ring, Valves, sleeves, sliders, pins, split pins, angle brackets, side plates, brackets, connecting rods, piston rods, cylinders, terminal fittings, filling, triggers for filling valves, rotated by a small angle by the valve opening mechanism After that, the slider is lifted up a certain distance. At this time, the sleeve lifts the valve under the action of the spring. At this time, the sealing air ring does not work, and the compressed gas in the upper part of the cylinder can pass through the middle of the valve and the spool tube. The small hole flows into the inside of the bottle. When the pressure inside the bottle and the pressure in the upper chamber of the hydraulic cylinder are balanced, the valve tube is lifted up by the action of the spring and the spring. The sealing ring does not seal, and the liquid can pass through the valve. The outer wall of the core tube flows into the interior of the bottle, and the gas inside the bottle flows back to the upper part of the filling cylinder through the vent hole and the valve in the middle of the valve core tube, and the filling valve is in the open state; when the liquid inside the bottle contacts the lower part of the valve core tube When the gas inside the bottle cannot pass The core tube flows back to the upper part of the filling cylinder. As the liquid continues to flow downward, when the gas pressure inside the bottle is balanced with the gas pressure in the upper part of the hydraulic cylinder and the liquid height inside the hydraulic cylinder, the liquid inside the hydraulic cylinder no longer flows into the bottle. Internally, this defines the distance between the liquid level in the bottle and the mouth of the bottle. It also specifies the capacity of the liquid inside the bottle. Changing the length of the valve tube can change the distance of the liquid level in the bottle from the mouth of the bottle. The function of the water separation ring is to make the liquid flow down the bottle wall so as not to affect the backflow of the gas.

Shut-off valve When the filling valve rotates to the closed position with the filling cylinder, the valve closing mechanism rotates the trigger at an opposite angle to that when the valve is opened. The fork shifts the sleeve to move the valve and the spool tube downward at the same time. The gas sealing channel and the water sealing ring are closed at the same time, and the filling valve is closed again; when the bottle is blasted during the gas filling or filling process, the valve and the valve core tube are in the upper part of the filling cylinder. The gas is automatically moved down by the action of the gas to close the filling valve.

The pressure relief is in contact with the arcuate guide of the pressure relief mechanism, and the curved guide plate moves the plunger to the right by a certain distance. The sealing ring of the plunger does not seal, and the gas in the upper part of the bottle is discharged. Into the atmosphere, make it equal to atmospheric pressure, and the entire filling process is over.

The mechanical spring isobaric filling valve has the obvious advantages of fast filling speed, simple structure, sensitive action, and easy to realize bottle-free filling, and can be used when the pressure is insufficient to cause the bottle to burst. Automatically close the valve, and easy to clean, good alignment performance, easy to disassemble.

Crowd Control Barrier introduction:

Heavy duty crowd control/pedestrian barriers (Portable Fence, Temporary fence or Removable Fence
, Steel Barriers ,welded Wire mesh rolls), it plays the role of protection in house site, major public events, sports, concerts, festivals, gatherings, swimming pools and many other uses for secure construction sites and private property.

Inter-locking "hook and eye" systems for quick installation. Crowd control barriers are designed to be linked together via hooks. Each hook is made of a 5//8" steel rod. The feet are either flat or arched.

crowd control barrier surface treatment:   hot dip galvanized or powder coated after welded

crowd control barrier size: 914mm*2440mm, 1090*2000mm, 1090*2010mm, 940*2500mm

crowd control barrier frame: O.D 20, 25, 32, 40, 42, 48

crowd control barrier infill picket: OD 12, 14, 16, 20

crowd control barrier feet: Flat feet, Bridge feet and Tube feet
