Product Description

Gate valve adopts balanced floating sealing structure, suitable for the pressure is not greater than 40MPa, temperature is not higher than 120ºC oil, gas and other pipelines, as the control medium opening and closing and adjusting device, the product structure design is novel, appropriate material selection, strict measurement, light operation, with strong corrosion resistance and erosion resistance performance, is an ideal equipment. This series of products adopts the balanced floating sealing structure, suitable for the pressure is not greater than 40MPa, the temperature is not higher than 120ºC on the oil, Tianzhan and other pipelines, as the control medium of the opening and closing and adjusting device, the product structure design novel, appropriate material selection, strict measurement, light operation, with strong corrosion resistance and erosion resistance performance, is an ideal equipment.

Z83Y clamp high pressure flat gate valve structure characteristics and working principle
1, the use of floating seat, reliable sealing, flexible opening and closing.
2, the lower part of the gate has a diversion hole, and give guidance, while the sealing part are sprayed welding hard gold, erosion resistance.
3, the valve body carrying capacity is high, the channel is straight through, fully open, and the gate diversion hole through and straight pipe similar, flow resistance is very small. The valve stem adopts composite packing and multiple sealing, which makes the sealing reliable and the friction is small.
4, close the valve, turn the hand wheel clockwise, the ram down to the bottom, due to the effect of medium pressure, the inlet end of the seal seat to the direction of the ram. Form a larger sealing pressure, so as to form a channel seal. At the same time, press the ram towards the outlet end sealing seat to become a double seal.
5. Because of the double seal, the wearing parts can be replaced without affecting the work of the pipeline. This is an important feature that our products have priority over similar products at home and abroad.
6. When opening the ram, rotate the handwheel counterclockwise, the ram moves upward, and the diversion hole is connected with the channel hole. With the rise of the gate, through the hole gradually increased, when the limit position, the diversion hole and the channel hole coincide, at this time fully open.
Z83Y clamp high pressure plate gate valve use, maintenance, maintenance and precautions
1. The strength and sealing test have been made before the valve leaves the factory, and all connections should be maintained in the initial state when used.
2, this series of valve operation hand wheel is marked with the opening and closing rotation sign, the upper part of the open rod type is equipped with the opening and closing height scale for adjustment instructions.
3. When welding the valve and pipeline, the valve should be opened, and the neck should be properly protected with damp material to minimize high temperature heat conduction to prevent damage to the sealing packing parts.
4, close the valve is strictly prohibited to use the afterforce rod, the gate closed to the top of the handwheel should be turned 1/2 turn to make the gate in a floating state.
5, the valve in the process of use, should be regularly injected into the valve cap grease joint quantitative grease.
6, the valve in the process of use, such as leakage due to wearing parts, should be replaced in time.
7, the valve in the maintenance process, the inner cavity should be cleaned, assembly should be the transmission parts grease.
8, valve storage period, the ram should be in the closed position, long-term storage should be placed in a ventilated dry place, regular inspection and maintenance.
