Moving down keeps air bleeding valve in the open state, and the bottom end of the connecting rod is equipped with the bending section for shelving float.
The beneficial effects of the invention are as follows：
1, by the setting of filter screen, steam is made to be condensed on filter screen, to allow steam to be completely separated, while strainer energy
Thoroughly remove the impurity mixed in gas；
2, float of the present invention is not to be fixedly connected with connecting rod, when gas reaches discharge chamber by air collecting chamber
When, since two-way pressure is consistent, float moves downward under the effect of gravity, and connecting rod is driven to move down, to
Open exhaust valve exhaust；If since exhaust gradually completes, when liquid level rises and pushes float upward, exhaust plug is not by downward
Power and can not open, while vapour lock can be formed in discharge chamber, to prevent liquid to be leaked from exhaust valve port.
Based on the above technical solution, the present invention can also be improved as follows.
Further, the axial length of the air collecting chamber is 150-200mm.
Advantageous effect using above-mentioned further scheme is：Compared with air collecting chamber in the prior art, gas collection of the invention
Chamber axial length is long, keeps gas-liquid mixture longer in the air collecting chamber residence time, is conducive to the separation effect for improving gas-liquid
Rate.Inventor is found surprisingly that by a large amount of research experiment, when the axial length of air collecting chamber is 150-200mm, Ke Yiming
Aobvious reduce even avoids air water mixing phenomenon.
Further, the filtering accuracy of the filter screen is 80-200 mesh.
Advantageous effect using above-mentioned further scheme is：Further being conducive to steam, preferably condensation is same on filter screen
When remove the impurity mixed in gas.
Further, the placement section is in hook-shaped, and float is placed in the knee of hook.
Advantageous effect using above-mentioned further scheme is：Placement section is in hook-shaped, is conducive to float and is preferably placed in put
It sets at portion, connecting rod vertical direction is arranged to be used cooperatively with the float of bending section, it is ensured that can only be vented cannot drain, and prevent
The phenomenon that leak.
Further, the exhaust outlet of the air bleeding valve is horn-like structure, and is horizontally disposed with, and the exhaust plug is connection bullet
The chondritic of spring, under natural conditions, chondritic are located at horn-like inside configuration and close big opening end, spring with connect
The top of bar is fixedly connected, and when connecting rod moves down, spring is pulled to be moved to big opening end, is further pulled on chondritic to big
The movement of mouth end, air bleeding valve is in the open state, to be exhausted.
Further, the bottom of the air bleeding valve is equipped with the convenient screw thread being connect with other equipment.
Further, the float can arbitrarily move up and down in connecting rod.
Take having the beneficial effect that for above-mentioned technical proposal：Opening or closing for air bleeding valve is adjusted by moving up and down for float
State has many advantages, such as simple and effective.
Description of the drawings
Fig. 1 is the structural schematic diagram of exhaust apparatus of the present invention.
In attached drawing, parts list represented by the reference numerals are as follows：
1, air bleeding valve, 110, exhaust plug, 2, filter screen, 3, float, 4, connecting rod, 5, exhaust outlet, 6, gas-liquid entrance.
Specific implementation mode
The principle and features of the present invention will be described below with reference to the accompanying drawings, and the given examples are served only to explain the present invention, and
It is non-to be used to limit the scope of the present invention.
As shown in Figure 1, a kind of exhaust apparatus, including air bleeding valve 1, filter screen 2, float 3 and connecting rod 4, the air bleeding valve 1
Bottom end be gas-liquid entrance 6, the bottom of the air bleeding valve 1 is equipped with the screw thread for being connect with other equipment, the air bleeding valve 1
Top is exhaust outlet；The exhaust ports of air bleeding valve 1 are equipped with exhaust plug 110.
The exhaust outlet of the air bleeding valve is horn-like structure, and is horizontally disposed with, and the exhaust plug is the ball of connecting spring
Shape structure, under natural conditions, chondritic are located at horn-like inside configuration and close big opening end.
The air bleeding valve 1 is internally provided with filter screen 2, and filter screen 2 will be separated into upper and lower two regions, lean on inside air bleeding valve 1
Top area at nearly exhaust outlet 5 is discharge chamber 7, and the lower region at gas-liquid entrance 6 is air collecting chamber 8.
Connecting rod 4 and float 3 are equipped in discharge chamber 7, the top of the connecting rod 4 is fixedly connected with one end of spring,
The other end of spring is connect with chondritic, and under natural conditions, chondritic blocks exhaust outlet, without exhaust, when a large amount of
Gas, which enters discharge chamber and forms downward thrust, pushes float to move downward, and then when connecting rod 4 moves down, pull spring to
