able to ensure the locked safe operation

The special structure of the patent elastic fire seat, overcome the past can only use type O rubber ring, will the limitations of the flat gate resilient seats applications extended to high temperature and high pressure field. Concerned expert thinks, this wrist ball application and the successful development of the province to promote the efficiency of mechanical and oil industry economic technology plays a key role in domestic also influenced, in market applications have wide prospect.

Flat gate is a closed parts as parallel disc slide power ball. Its close thing can be single disc or with open institutions in double disc.
Disc to seat compaction force is by the role and floating disc or floating seat the medium pressure to control. If is double disc flat gate, the two gate seen open institution can complement the compaction force.
Flat gate features:
1, fully closed structure, protective performance is good, suitalbe for the requirements
2, flat gate closing can automatically unloaded high-pressure lumen to ensure safe operation
3, in full open, channel smooth to flow resistance coefficient is tiny, without pressure loss, can connect primordial cleaning line
4, seat is o-shape sealing ring seal and applying pre-pressures floating seat structure, make flat gate import and export bidirectional seal; And the structure of the opening and closing of the valve is only common torque 1/2, can achieve easily open and close the valve
5, with the sealing ability by stuffing structure, solar collectors without constant adjustment, open and shut very deft, and sealing is reliable, stuffing box place an assisting sealing grease injection structure, sealed performance is absolutely reliable and get a true zero leakage; Solved the common valve packing place the easiest leak of ills
With the current world top technical and fills up the domestic blank resistance to high sulfur acid special flat gate - CL150LB, high-pressure CL900-2500LB - DN25-500 flat gate, has already successfully developed. At present, the products have been successfully applied in China petrochemical puguang gas field development ground airtight gathering and transportation engineering subject in question. According to understand, magic towel this product has the flow resistance small, flow and can connect sweeper function and has advantages of hoist lightweight, and can be widely used in oil and gas containing sulphur of mining and airtight gathering and transportation, oil and natural gas transmission pipelines, refineries, such as control working medium circulation and deadline lifting device.
According to the requirements of project, this valve has manual, bevel gear transmission, explosion-proof electric etc transmission ways. This valve is designed to have the valve position switch instructions, stem the incorrect operation to protect, prevent the protection, wristband able to ensure the locked safe operation, avoid valve wrong operation. This product adopts single disc hard seal, floating patent technology seat, guarantee not into the seat behind, sundry with fire and anti-static function, the valve for the company the blank casting smelting, casting.
