Abstract
The utility model provides a big discharge of fumes and gas air bleeding valve draws together the valve body, is provided with exhaust apparatus's valve gap on it, and the last floater of the linkage that can fluctuate sets up inside the valve body with keg float down, and the intermural guiding mechanism that is provided with in lower keg float's lateral wall and the valve body goes up the floater and when keg float all lies in the valve body bottom down, and big discharge of fumes and gas exhaust when going up the floater and floating with keg float is whole down, keeps the exhaust, goes up the floater and breaks away from when keg float floats down, and is sealed with exhaust apparatus. The beneficial effects of the utility model are that the discharge of fumes and gas is big, can realize the low pressure water -stop, and the sphere is sealed, and is sealed respond well.
Description
Technical field
The utility model belongs to outlet valve technical field, especially relates to a kind of large air displacement outlet valve.
Background technique
Outlet valve is requisite auxiliary element in pipe-line system, is widely used in boiler, petroleum gas, water supply and sewerage pipeline.Often be arranged on the place such as commanding height or elbow, excessive gas, raising pipeline road utilization efficiency and reduction energy consumption in purging line.Existing outlet valve air pressure easily produces gas time excessive and blocks up phenomenon, if increase the weight of floating, then needs very high hydraulic pressure to realize water-stop, easily produces leak of liquid.A kind of large air displacement outlet valve realizing low-pressure water sealing awaits further research and development.
Model utility content
The purpose of this utility model is to provide a kind of large air displacement outlet valve, can increase substantially air displacement.
The technical solution of the utility model is: the large air displacement outlet valve of one of the present utility model, comprise valve body, be provided with the valve gap of venting gas appliance, upper floating ball and the lower keg float of the interlock that can fluctuate are arranged on valve inner, guide mechanism is provided with between the sidewall of lower keg float and the inwall of valve body, when upper floating ball and lower keg float are all positioned at body base, large air displacement exhaust, when upper floating ball and lower keg float entirety are floated, keep exhaust, when keg float floats under upper floating ball departs from, venting gas appliance is sealed.
Further, described lower keg float is provided with guide hole, and upper floating ball coordinates guide hole and lower keg float to be flexibly connected by guide rod, and the bottom of described guide rod is provided with pin, and the degree of depth of pin is greater than the height of guide hole.
Further, the bottom of lower keg float and side are evenly equipped with many axial vent slots, and described upper floating ball and lower keg float and axial vent slot are on same axis.
Further, described venting gas appliance is exhaust port, and exhaust port is provided with seal ring, interstage sleeve.
The advantage that the utility model has and good effect are:
1, while upper floating ball and the interlock of lower keg float, be aided with certain activity, effectively balance the demand between air displacement and sealing hydraulic pressure, air displacement is large, combination is positioned at bottom upper floating ball and lower keg float weight, make exhaust pressure and air displacement improve more than five times, avoid the defect that gas blocks up phenomenon, instantaneously venting capacity difference, achieve low-pressure water sealing.
2, form spherical sealed between ball float and venting gas appliance, relative to plane sealing, sealing effect is better.
3, described upper floating ball and lower keg float and guide hole are on same axis, and the axial vent slot of formation, can increase substantially air displacement.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure:
1-valve body, 2-upper floating ball, 3-packing ring, 4-pin, keg float under 5-, 6-seal ring, 7-interstage sleeve, 8-O shape is enclosed, 9-valve gap, 10-hexagon socket cap head screw, 11-spring washer, 12-packing ring, 13-guide rod.
Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
As shown in Figure 1, the large air displacement outlet valve of one of the present utility model, comprise valve body 1, be provided with the valve gap 9 of venting gas appliance and the upper floating ball 2 of valve inner and lower keg float 5 can be arranged on fluctuating, guide mechanism is provided with between the sidewall of described lower keg float 5 and the inwall of valve body 1, such as guide groove and guide block, the bottom of lower keg float 5 and side are evenly equipped with many axial vent slots, described upper floating ball 2 and lower keg float 5 and axial vent slot are on same axis, the lower center position of lower keg float 5 is provided with guide hole, the top of guide rod 13 is fixed with upper floating ball 2, it is outside that the other end extends to lower keg float 5 through guide hole, the bottom of guide rod 13 is provided with pin 4, packing ring 3 is provided with above pin 4, distance between described pin 4 to guide rod 13 top is greater than the height of guide hole, the middle position of valve gap 9 is provided with exhaust port, seal ring 6 is provided with in exhaust port, interstage sleeve 7, valve gap 9 is by hexagon socket cap head screw 10, spring washer 11 and packing ring 12 are assemblied in valve body 1 top, valve body 1, O shape circle 8 is also provided with between valve gap 9.
The working procedure of this example: when being vented, upper floating ball 2 and lower keg float 5 are all positioned at bottom, the exhaust of large air displacement can be ensured, when liquid enters valve body 1 inside, when only having lower keg float 5 contact liq, upper floating ball 2 and the overall slowly rise of lower keg float 5, keep exhaust simultaneously, when liquid level continues to rise to upper floating ball 2, because upper floating ball 2 is comparatively light, can float fast and utilize the height difference of pin 4 depth and guide hole to realize departing from, upper floating ball 2 floats up to seal ring 6 place in exhaust port, by vent hole seal, to ensure the requirement that low-pressure water seals.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
