(2) The sealing surface is not easy to wear and abrasion, good sealing, there is no relative sliding between the valve flap and sealing surface when opening and closing, so the abrasion and abrasion are not serious, the sealing function is good, and the service life is long.
(3) When opening and closing, the flap stroke is small, so the height of the external thread stop valve is smaller than the gate valve, but the planning length is longer than the gate valve.
(4) large opening and closing torque, opening and closing more strenuous, opening and closing time headmaster.
(5) large fluid resistance, due to the media channel tortuous body, fluid resistance, power consumption.
(6) When the nominal pressure PN is less than or equal to 16MPa, the media is normally used downstream and the media flows upwards from below the valve flap. When the nominal pressure PN≥20MPa, the countercurrent is usually selected, and the medium is lighter from the valve flap. To increase the seal can. When used, the external thread stop valve medium can only be one-way activities, can not change the direction of activity.
(7) When the valve is fully open erosion.
J91Y-320P high-pressure card stop valve stem axis and seat sealing surface vertical. Stem opening or closing stroke is relatively short, and has a very reliable interception action, making this valve suitable as a media interception or scheduling and conservation.
J91Y-320P high-pressure card stop valve benefits:
1, the planning is simple, more convenient to make and repair.
2, small work trip, opening and closing time short.
3, high-pressure card stop valve sealing, sealing surface friction, longer life.
4, high-pressure card stop valve body planning methods are straight-through, direct current and right angle. Straight-through is the most common plan, but its resistance to fluids is greatest. Direct flow fluid resistance is small, more for solid particles or viscous fluid. Multi-choice right-angle casting body, suitable for smaller through, the higher pressure of the external thread stop valve.
5, in the process of opening and closing the sealing surface of the friction than the gate valve is small, wear-resistant.
6, usually only a sealing surface, manufacturing skills, easy to repair.
