Described outlet valve inside is provided with filter screen, and outlet valve is separated into two regions by filter screen, is exhaust cavity near exhaust ports, is air collecting chamber near gas-liquid separation ingress;
In exhaust cavity, be provided with connecting rod and float, the top of described connecting rod is fixedly connected with exhaust plug, and connecting rod moves down and makes outlet valve be in open mode, and the bottom of described connecting rod is provided with the curved part for shelving float.
The invention has the beneficial effects as follows:
1, by the setting of filter screen, steam is condensed on filter screen, thus allow steam thoroughly be separated, filter screen can thoroughly remove the impurity mixed in gas simultaneously;
2, float of the present invention and connecting rod are not what be fixedly connected with, when gas arrives exhaust cavity by air collecting chamber, because two-way pressure is consistent, float is at the moved downward of self gravitation, and drive connecting rod to move down, thus open outlet valve exhaust; If completed gradually due to exhaust, liquid level rise and promote float upwards time, exhaust plug, not by downward power and cannot opening, can form vapour lock simultaneously in exhaust cavity, thus prevents liquid to leak from exhaust valve port.
On the basis of technique scheme, the present invention can also do following improvement.
Further, the axial length of described air collecting chamber is 150-200mm.
Adopt the beneficial effect of above-mentioned further scheme to be: compared with air collecting chamber of the prior art, air collecting chamber axial length of the present invention is long, and the time that gas-liquid mixture is stopped at this air collecting chamber is longer, be conducive to the separation effect improving gas-liquid.Inventor is found unexpectedly by a large amount of research experiments, when the axial length of air collecting chamber is 150-200mm, obviously can reduces and even avoid air water mixing phenomenon.
Further, the filter precision of described filter screen is 80-200 order.
The beneficial effect of above-mentioned further scheme is adopted to be: to be conducive to steam better condensation on filter screen further and to remove the impurity mixed in gas simultaneously.
Further, described placement section is hook-shaped, and float is placed in the bending part of hook.
Adopt the beneficial effect of above-mentioned further scheme to be: placement section is hook-shaped, is conducive to float and is better placed in placement section place, connecting rod vertical direction arrange with the float of curved part with the use of, can ensure to be vented can not draining, stops the phenomenon of leaking.
Further, the relief opening of described outlet valve is horn-like structure, and is horizontally disposed with, and described exhaust plug is the spheroidal structure of linking springs, under nature, spheroidal structure is positioned at horn-like inside configuration and close big opening end place, and spring is fixedly connected with the top of connecting rod, when connecting rod moves down, spring is pulled to move to big opening end, pull spheroidal structure to move to big opening end further, outlet valve is in open mode, thus is exhausted.
Further, the bottom of described outlet valve is provided with screw thread that is convenient and other equipment connections.
Further, described float can move up and down arbitrarily on connecting rod.
Take the beneficial effect of technique scheme to be: by float move up and down regulate outlet valve open or close state, there is the advantages such as simple and effective.
Accompanying drawing explanation
Fig. 1 is the structural representation of venting gas appliance of the present invention.
In accompanying drawing, the list of parts representated by each label is as follows:
1, outlet valve, 110, exhaust plug, 2, filter screen, 3, float, 4, connecting rod, 5, relief opening, 6, gas-liquid entrance.
Embodiment
Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
As shown in Figure 1, a kind of venting gas appliance, comprise outlet valve 1, filter screen 2, float 3 and connecting rod 4, the bottom of described outlet valve 1 is gas-liquid entrance 6, the bottom of described outlet valve 1 is provided with for the screw thread with other equipment connections, and the top of described outlet valve 1 is relief opening; The exhaust ports of outlet valve 1 is provided with exhaust plug 110.
The relief opening of described outlet valve is horn-like structure, and is horizontally disposed with, and described exhaust plug is the spheroidal structure of linking springs, and under nature, spheroidal structure is positioned at horn-like inside configuration and close big opening end place.
