Abstract
The invention relates to an automatic vent valve capable of replacing a supporting point. The vent valve comprises a round automatic vent valve, a square automatic vent valve, a lower shell, an upper cover and a floating ball. The vent valve is characterized in that the upper part of a copper joint which is provided with an outer screw and comprises an air hole, a screw thread connecting part and a valve stop is directly screwed with the bottom of the lower shell through the screw thread; the copper joint with the outer screw is higher than the inner bottom of the lower shell, thus the copper joint can play a role of jacking the floating ball while the floating ball drops; and the upper part of the copper joint with the outer screw is provided with the air hole convenient for air inlet and outlet. Because the structure of the vent valve is simplified and improved, the vent valve has simple structure, is convenient to disassemble and is not easy to generate impurities and dirt under the condition of long-time works; the floating ball has good stability and is not easy to deviate, thus the automatic vent valve can be used for replacing an automatic vent valve with a protrusion in the known fields, and the manufacturing cost can be reduced; and the vent valve can achieve the effects of returning air and preventing vacuum in the valve body. In addition, the vent valve can be applied to serial general matched products without replacing the lower shell.
Description
Technical field
The present invention relates to the automatic control pressure vent door device used on a kind of domestic heating pipe-line system, particularly a kind of automatic control pressure vent that can replace having the strong point.
Background technique
At present, known as China Patent No.: the disclosed a kind of outlet valve of 02280741.1 and 200320112523.2 utility model patents with isolating frame, housing bottom is provided with a projection, in order to ball float and housing bottom are kept apart, its drawback is: when making the lower shell body of outlet valve, because of need punching press or casting have a projection or a plurality of boss at least,, gas can be passed through smoothly in order to ball float and housing bottom are kept apart.Do not have protruding lower shell body to cause cost up, economic waste at ratio aspect the grinding tool of making the outlet valve lower shell body like this, when making serial general outlet valve, need change the lower shell body of not being with projection, caused personnel's waste so again.Obviously, be further to have improved manufacture cost.In addition, the general product problem aspect that does not match of series need solve.
Summary of the invention
At the deficiency that above-mentioned technical problem exists, the object of the invention provides a kind of automatic control pressure vent that can replace having the strong point.
Technological scheme of the present invention is as follows:
A kind of automatic control pressure vent that can replace having the strong point comprises circular and square automatic control pressure vent; Also comprise lower shell body, loam cake and ball float, it is characterized in that, the top of the copper sleeve of the outer silk of the band of being made up of pore, screwed connection portion, valve shelves and the direct screw thread in bottom of lower shell body are spirally connected, the copper sleeve of the outer silk of described band has the height of the inner bottom part that is higher than lower shell body, can play the effect that ball float withstands ball float when sagging, be provided with the convenient pore that gas is used that passes in and out on the top of the copper sleeve of the outer silk of band.
Described pore, screwed connection portion, valve shelves are integral structures, and the pore on the copper sleeve top of the outer silk of band is to saw round mouth position polishing at an upper portion thereof or the symmetrical air inlet/outlet that is sawn into emery wheel or wheel.
The copper sleeve inside of silk is provided with and is used for preventing the filter screen that impurity enters outside band, and described filter screen is made of stainless steel, and described filter screen outer installment has limit portion.
The present invention has been because of having carried out the summary improvement in configuration aspects, has simple in structurely, and convenient disassembly under situation about working long hours, is difficult for producing impurity and dirt.The ball float good stability is not easy to depart from.Such automatic control pressure vent can substitute the automatic control pressure vent that " projection " arranged in known field, and manufacture cost can reduce.Return-air can be accomplished in valve body not only but also vacuum can be prevented.In addition, can be used on the general supporting product of series, not need to have changed lower shell body.
Description of drawings
Fig. 1 is a sectional structure schematic representation of the present invention.
Among the figure: 1 lower shell body, 2 loam cakes, 3 relief openings, 4 pores, 5 sealing rubber pads, 6 float bar, 7 ball floats, 8 screwed connection portions, 9 valve shelves, 10 filter screens.
Embodiment
As shown in Figure 1, lower shell body 1 is spirally connected with loam cake 2 screw threads, loam cake 2 be provided with relief opening 3 and float bar 6 and and float the structure that bar 6 flexibly connects, float bar 6 and be spirally connected with ball float 7.Be spirally connected by the copper sleeve of silk outside being with bottom screw thread direct and housing 1 in lower shell body 1 bottom.The copper sleeve of the outer silk of described band is made up of pore 4, screwed connection portion 8, valve shelves 9, and pore 4, screwed connection portion 8, valve shelves 9 are integral structures.The top of the copper sleeve of the outer silk of band is pore 4, and described pore 4 is arranged on the top of the copper sleeve of the outer silk of band.Symmetrical air inlet/outlet with polishing or be sawn in emery wheel or wheel saw round mouth position at an upper portion thereof is pore 4 again.Must tighten when the copper sleeve of lower shell body 1 and the outer silk of band is spirally connected and put in place, the top of the copper sleeve that this belt transect is outer is higher than the inner bottom part of lower shell body 1, also can play the effect of withstanding ball float 7.Pore 4 is effects of playing convenient turnover gas when ball float 7 is sagging.Can accomplish like this in valve body, can prevent vacuum again by return-air.The copper sleeve of the outer silk of band and the joint of lower shell body 1 are provided with sealing rubber pad 5.
Such automatic control pressure vent can substitute the automatic control pressure vent that " projection " arranged in known field, and manufacture cost can reduce.In addition, can be used on the general supporting product of series, not need to have changed lower shell body 1.
Be provided with at housing 1 inner bottom part and be used for preventing the filter screen 8 that impurity enters.Described filter screen 8 usefulness stainless steels are made.Described filter screen 8 outer installment have limit portion.
