1. Main features of PE flat gas gate valve:

PE gas flat gate valve is a new generation of gas valves, is a special gas flat gate valve for direct buried use, PE gas flat gate valve design unique. Novel structure, technical performance is good, mainly is suitable for the city gas pipeline conveying and cutting medium, can be buried underground, and PE pipe connected directly, without gangsu conversion transition joint, reduce the project cost, build a just above the valve cover valve chamber, can on the ground all the operation and maintenance, sealed performance is good, small flow resistance coefficient, convenient operation and maintenance, long service life, such as natural gas, city gas, liquefied petroleum gas pipeline ideal accessory products.

4.PE flat gas gate valve product structure characteristics

1, PE gas flat gate valve and PE pipe connection: the two ends of the valve for PE pipe, using the principle of steel and plastic conversion joint, and the valve into one, so that the PE pipe and the use of electric sleeve direct connection, simple and convenient, greatly reduce the cost of steel valve using steel and plastic conversion joint.

2, PE gas plate gate valve middle connection (valve body bonnet connection) : the middle connection bolts adopt the countersunk hole design, to ensure that the bolts do not leak out, improve the anti-corrosion performance of the valve.

3. Sealing reliability of PE gas flat plate gate valve:

(1) valve body, valve cover.

Gate and other pressure components are steel materials, not due to the time and temperature changes and deformation, so that the seal is reliable, not to open or close the phenomenon.

(2) seat sealing surface inlaid with RPTFE, with a soft, hard double seal.

Parallel gate in the process of switching, always in line with the seat sealing surface, can be removed from the gate stolen, more reliable seal.

(3) when the valve is fully open or fully closed, the sealing surface of the seat is not subject to the erosion of the medium, effective protection of the sealing surface.

(4) a floating structure with a rubber seal or spring preload on the back of the seat to seal the valve even at very low pressure

4, double isolation function: the valve is in the closed state, both sides to seal, completely cut off the medium to seal, and no pressure in the cavity.

5, elastic seal: the seat is floating double seat, the outer circle USES the o-ring seal piston effect principle, the back elastic preload to compensate the seal, parallel gate only need to contact with the seal ring in place, no additional force to seal.

6, replaceable seat: the seat is installed on the body floating structure, can be disassembled and replaced online, and two-way sealing.

7, packing seal, valve cover stuffing box adopts the principle of piston seal set 0 type and V type pressure seal structure, the need to adjust, and very light, improves the performance of the valve packing is more reliable, solved the packing place of universal valves to be easiest leak outward ills, and the packing seal structure so that it is far less than PE ball valve opening and closing torque.

8. Dispersing function: the dispersing pipe can be set on the left and right sides of the valve body, thus replacing the dispersing pipe set by the pipe, thus saving the cost.

9, closed indication: the fully closed opening and closing indicator needle can be basically consistent with the valve opening and closing degree, and can make the operator clearly observe the valve opening and closing situation.

10. Anticorrosion measures: the appearance of the valve is anticorrosive with epoxy coal pitch, and the service life of the pipeline is the same.
