Abstract
The utility model relates to an ultra-short structure type micro-resistance slowly closed check valve in conveying a fluid pipe line. The valve is mainly composed of a valve body, a micro-resistance slowly closed apparatus, a valve board, a valve board axle, a counter weight poise, and a sealing ring. The valve body is welded into ultra-short type by adopting the metal plate material; the value body not only has smooth surface and resists high medium pressure, but also has light weight, debases the cost and is easy to install. The valve plate is circular; after rotating and starting up, the liquid can get across the circumference, and decreases flow resistance. The valve plate is furnished with the sealing ring which can be replaced; the sealing ring not only has good sealing performance, but also prolongs the service life of the valve plate. The micro-resistance slowly closed apparatus profitably restricts the liquid producing a water hammer when the liquid changing direction sharp, and the apparatus makes the value is more safe and reliable to use.
Description
The utility model belongs to the universal machine technical field, a kind of ultrashort structure type Tiny Drag Slow Shut Check Valves of particularly using in the conveyance fluid pipeline.
In the conveyance fluid pipeline that pump promotes, mostly using valve body is the safety check of cast iron, and this just all exists the defective of valve body resistance to compression degree difference.Longer because of valve body again, its valve plate is a ligule, and not only valve body is heavy, after valve plate revolves and opens still convection cell big resistance is arranged
The utility model is intended to overcome the above-mentioned defective of prior art, and provides a kind of valve body light and anti-high pressure, and valve plate is opened the little ultrashort structure type Tiny Drag Slow Shut Check Valves of back convection cell resistance.
For achieving the above object, valve body of the present utility model adopts sheet metal to be welded into super-short, the anti-high pressure of smooth surface not only, and in light weight, reduce and subtract this, be suitable for installation.Valve plate is changed ligule in the past for circular, opens the back fluid and can pass through around valve plate, reduces the resistance of valve plate convection cell.Corresponding part at valve plate and check mouth is provided with removably seal ring, and not only good airproof performance, and seal ring is replaceable, has prolonged valve plate working life.
Owing to take above-mentioned technical solution, advantage of the present utility model: the one, valve body is a ultrashort structure type, and is not only in light weight, reduce cost, be suitable for installation, and anti-high pressure; The 2nd, valve plate is circular, open the back fluid can from around pass through the resistance of minimizing valve plate convection cell; The 3rd, on valve plate, be provided with removably seal ring, good airproof performance not only, and prolonged working life of valve plate.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the side view of Fig. 1.
Fig. 3 is the structural representation of valve plate.
Below in conjunction with accompanying drawing, elaborate specific embodiment of the utility model and working principle.
Referring to Fig. 1, Fig. 2, Fig. 3 as can be known, the utility model mainly is made of valve body 1, micro-resistance slowly-closed device 2, valve plate 3, valve shaft 4, counterweight stone roller 5, seal ring 6 etc.Valve body 1 adopts sheet metal to be welded into super-short, and valve shaft 4 strings are on valve body 1, and valve plate 3 is installed on the valve shaft 4, also is provided with counterweight stone roller 5 at an end of valve shaft 4.On valve body 1, be provided with micro-resistance slowly-closed device 2, on valve plate 3, also be provided with removably seal ring 6.
Working principle: the pump outlet port that the utility model is installed in fluid circuit.When pump was worked, fluid was dashed valve plate 3 by the water intake of valve body 1 and opens, and at this moment counterweight stone roller 5 is depressed into valve plate 3 maximum enable possition again, and fluid can flow into the water outlet of valve body 1 around the valve plate 3, to reduce the resistance of valve plate 3 convection cells.Simultaneously, fluid also ejects its piston by micro-resistance slowly-closed device 2 the outer segment distance of check mouth of valve body 1.When the pump stall, fluid commutates fast, and just the water outlet by valve body 1 rushes at the whereabouts check fast with valve plate 3, to reduce capacity of reflux.Touch after the piston tip of micro-resistance slowly-closed device 2 just progressively Slow Close when valve plate 3,, reach and eliminate the water hammer purpose so that alleviate water impact.After the check mouth on seal ring on the valve plate 36 and the valve body 1 compresses, thoroughly reach the non-return purpose.
