A kind of gas-filled type rubber pneumatic bag safety valve
Technical field
The utility model relates to a kind of gas-filled type rubber pneumatic bag safety valve technical field, the especially a kind of safety valve field that can carry out to gas pressure in air bag pressure release control.
Background technique
Gas-filled type rubber pneumatic bag is widely used in engineering construction, can be divided into air-bag for ship, movement air bag, hoisting gasbag, floating gasbag, plugging air bag, building air bag etc. according to purposes difference, be a kind of innovative product with China's independent intellectual property right, be widely used in the fields such as floating that help of the upper and lower water of boats and ships, caisson lifting movement, other weight carrying, installing engineering under water.The application of air bag is subject to place restriction few, without large-scale machinery, therefore can shorten construction period, save substantial contribution.Air bag utilizes pressurized air as buffer medium, in use exist air bag to occur the danger of air bag explosion because carrying extrusion-deformation causes internal pressure to raise, there is serious personal injury and property loss, simultaneously according to the relevant provision requirement of CB/T3795 " row, lower water air bag on boats and ships ", high-pressure gasbag is answered mounting safety valve, with the internal pressure of release air bag.The domestic safety valve that does not also have Production design to meet air bag installation requirement at present, because the feature that the cone structure of air bag is different, even if the safety valve on employing market can not can be arranged on air bag completely, and other industrial fields safety valve used can not meet performance and installation requirement equally, gas-filled type rubber pneumatic bag is at home substantially blank with safety valve field, there is a kind of safety valve that can be adapted to gas-filled type rubber pneumatic bag to be developed, improve usage safety performance, the fortuitous casualty that reduction explosion brings and the risk of loss.
Model utility content
In order to overcome above-mentioned the deficiencies in the prior art; the utility model provides a kind of gas-filled type rubber pneumatic bag safety valve; especially a kind of safety valve that can carry out to gas pressure in air bag pressure release control; the problem that efficiently solves high pressure and ultrahigh pressure air bag configuration safety valve, realizes personal safety and air bag has been used to important protective action.
The technological scheme that the utility model adopts is: connecting valve seat 6 outside the endoporus of the flange plate 4 of installing by bolt 7 on the cone end valve 2 of air bag 1, guard shield 17 is installed in inner side, valve body 10 is arranged in valve seat 6 and connects the mandrel 15 with Compress Spring 16 by adjusting screw 16, Compress Spring 16 is arranged between the bottom boss of mandrel 15 and the spring seat 18 on top, the pressure-type safety valve of composition spring control off-load.
The utility model is intended to realize by gas-filled type rubber pneumatic bag safety valve the automatic deloading of air bag inner high voltage gas.When air bag work, its internal pressure of pressurized raises; in the time that the air pressure rising in air bag exceedes specified value; spring 16 is compressed; back down valve body 10, open pressure relief opening, safety valve exhausting air; prevent that air bag inner air pressure from exceeding specified value; realize automatic deloading, realize personal safety and air bag have been moved to important protective action, and can facilitate the quick inflation/deflation operation of air bag.
The mounting structure of the described safety valve of the utility model is: the outside connecting valve seat 6 of flange plate 4 endoporus of installing by bolt 7 on the cone end valve 2 of air bag 1; guard shield 17 is installed by bolt 3 in inner side at flange plate 4 endoporus, and mandrel 15 and spring 16 to its inside play a protective role.Pass through bolt 8 adpting flange lids 13, the protection that realizes valve seat 6 interior parts and the relief opening function of blind flange 13 on valve seat 6 tops.The interior installation valve body 10 of valve seat 6, adjusting bolt 14 and blind nut 12 have been installed in the center hole of valve body 10, Compress Spring 16 is arranged between the bottom boss of mandrel 15 and the spring seat 18 on top, the upper-lower position of the adjustable mandrel 15 of rotation of adjusting bolt 14 on valve body 10, realizes the variation of spring 16 compressive forcees.In order to carry out gas seal, realize the sealing of valve body 10 and valve seat 6 by seal ring 9, the seal ring 11 on mandrel 15 has played the leakage path that oozes between sealing mandrel 15 and valve body 10.
The working principle of the described safety valve of the utility model is: safety valve is normally closed property, while work below the pressure unloading value of regulation, the pressure of spring 16 compresses the seal ring 9 between valve body 10 and valve seat 6 by mandrel 15, and in realizing, outside gas is isolated, does not have seepage gas to occur.In the time that the pressure in air bag meets or exceeds the pressure unloading value of regulation, pressurized air increases the promotion bottom of mandrel 15 and the air pressure supporting plane of valve body 10, spring 16 is compressed, mandrel 15 promotes to move on valve body 10, thereby there is gap and expand in valve body 10 and valve seat 6 at seal ring 9 places, open like this pressure relief opening, realized gas and discharged fast.The a certain amount of rear pressure drop of air release in air bag, in the time that the thrust of gas pressure generation is less than the compressive force of spring 16, valve body 10 is by push-and-pull return, thus valve body 10 and valve seat 6 are realized sealing at seal ring 9, close pressure relief opening.
The pore that is useful on inflation/deflation on the valve body 10 of the utility model design, is upright opening and horizontal hole, and upright opening is corresponding with horizontal hole to communicate, and the quantity in hole should meet the demand of air flow rate.
The pore that is useful on inflation/deflation on the spring seat 18 of the utility model design, the quantity in hole should meet the demand of air flow rate.
Between the valve seat 6 of the utility model design and flange plate 4, be connected on valve 2 by bolt 7, rely on sleeve 5 to come the gap between adjusting control valve seat 6 and flange plate 4 simultaneously.
The inflation/deflation air-flow path of the described safety valve of the utility model is: the hole from guard shield 17 to spring seat 18 when venting, to the upright opening of valve body 10, to the horizontal hole of valve body 10, to the sealing surface of valve body 10, to blind flange 13, exit to air; Air-flow path when inflation is contrary with the air-flow path in when venting.
The flange plate 4 of the utility model design, by adjusting different-diameter and the mounting hole size of flange plate 4, can adapt to the installation requirement of Multiple Type specification, different-diameter series air bag valve 2.
The beneficial effects of the utility model are the problems that efficiently solve high-pressure gasbag configuration safety valve, realize personal safety and air bag have been moved to important protective action, are mainly manifested in:
1) safety valve adopts spring pressure control mode to realize high pressure unloading, realizes automatically and controlling.
2) mounting interface of safety valve adapts to the feature of product structure, can realize Series Configuration.
3) pressure unloading of safety valve can be realized by changing different springs the control of multiple pressure unloading.
4) safety valve can not only carry out releasing pressure automatically venting, in the time that air bag need to carry out Rapid degassing and fast aeration, can realize quick charging-discharging function by manual unlocking pressure relief opening.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
