Description
Technical field
The utility model relates to a kind of vacuum valve, is a kind of pressure vacuum valve peculiar to vessel specifically.
Background technique
Pressure vacuum valve realizes air inlet connected sum water-inlet-proof function by the opening and closing of pressure vacuum valve, realize the exhaust of ballast tank processing system, the pressure vacuum valve of existing use mostly adopts ball float mode, ball float is in low level under normal circumstances, air pipe head without closing, the water surface rise drive ball float to rise time ball float occluded air tube head.Its ball float mounting structure is complicated, be not easy to maintenance, and exhaust, draining are limited, there is use safety hidden danger.
Summary of the invention
For the above-mentioned deficiency of prior art, the utility model provides a kind of compact structure, the pressure vacuum valve peculiar to vessel of exhaust outlet safety and stability.
The technical solution of the utility model is: a kind of pressure vacuum valve peculiar to vessel, comprise valve body and ball float, it is characterized in that: described valve body comprises inner core, urceolus, upper cover and two side covers, inner core coaxial sleeve to be connected in urceolus and to be supported in urceolus, between inner core left and right side, hollow out is hollow out cavity, inner core top and bottom are respectively equipped with the suitable for reading and inner core end opening of the inner core being communicated with hollow out cavity, ball float mounts cover inner core left and right side through two side covers or protective net non-tight and is encapsulated in hollow out cavity, and the urceolus upper flap on urceolus top loads onto lid; The forward and backward side of described inner core is communicated with the urceolus end opening on urceolus bottoms with two air flues forming top between urceolus and be communicated with, two air flue bottoms; Cover is elevated under described inner core end opening or the interior coaxial connection of urceolus end opening, lower lifting bar is slidably matched and is located in lower lifting cover, lower lifting bar top connects the lower inner cap being arranged on corresponding lifting capping inner core end opening in hollow out cavity, described inner core is suitable for reading or urceolus is suitable for reading or upper cover interior edge face coaxially connects and is elevated cover, upper lifting bar is slidably matched and is located in lifting cover, and upper lifting masthead end connects the interior corresponding lifting capping inner core of the top connectivity part being arranged on two air flues inward upper cover suitable for reading.
Further, the bottom connection flange of described urceolus, urceolus end opening is communicated with mounting flange.
Further, described lower lifting cover also can coaxially be connected in mounting flange.
Further, described inner core end opening inwall is provided with seal ring.
Further, described inner core inwall suitable for reading and/or outer wall are provided with seal ring.
Further, described outer tube inner wall is evenly equipped with the many reinforcement gussets along air flue direction.
The utility model pressure vacuum valve adopts the excellent Q235-B of comprehensive mechanical performance to be welded; Ball float adopts polyethylene beautiful shape, good corrosion resistance; Seal ring adopts the neoprene sponge of good springiness, good corrosion resistance, and protective net adopts the good Stainless Steel Cloth of antiseptic property to make and plays protection against rodents, insect protected effect, and upper and lower inner cap adopts the good stainless steel of antiseptic property to process.
The ball float of pressure vacuum valve can move up and down, and can normally work when longitudinal and transverse inclination space-time pressure vacuum valve occurs boats and ships simultaneously, even if when liquid tank overflows dress water hammer, ball float also can not damage.
When ballast tank is intake, ballast tank internal air pressure raises, thus air pressure promote lower under cover rim lifting bar rise in lower lifting cover, lower inner cap is opened, and opens under 200-300mm water column pressure, is vented, draining is stable; When ballast tank draining, ballast tank internal air pressure declines, and by air flue, inward upper cover is upwardly opened, prevents ballast tank from occurring vacuum, open under 200-300mm water column pressure; The performance that sealing pressing carries cabin is stamped in upper and lower when ballast tank nitrogen injection.Seal ring between upper and lower inner cap and inner core, is effective to waterproof sealing.
