Abstract

The utility model discloses an automatic exhaust valve comprising a valve body. A connection structure for being connected with a pipeline is arranged at the bottom of the valve body. An exhaust hole is formed in the top of the valve body. An elastic balance device for balancing pressure in the pipeline is arranged in the valve body and comprises a spring and a float-ball plug, wherein the lower end of the spring is fixedly mounted in the valve body and the float-ball plug is arranged at a free end of the spring. The exhaust hole of the automatic exhaust valve is in a normally open state; when air in the pipeline is exhausted, water flows into the exhaust valve, then the float-ball plug floats to plug the exhaust hole under action of buoyancy, so that water leakage is avoided. If air is concentrated to some extent in the valve body during normal running of the pipeline, the level of water in the exhaust valve is lowered with falling of the float-ball plug, and thus, the exhaust hole is opened and air is exhausted from the exhaust hole. If a water pump stops working, negative pressure is generated in the pipeline, the float-ball plug falls, and a great quantity of air suction is achieved to balance pressure in the pipeline, so that safety of the pipeline is guaranteed.

Description

Automatic control pressure vent
Technical field
The utility model belongs to valve technology field, is specifically related to a kind of automatic control pressure vent.
Background technique
Valve installation in various pipe-line systems, is used for controlling pressure, flow and the flow direction of fluid.The correct valve body of selecting how is the key point of sealability, strength character, adjusting function, performance and the trafficability performance of realizing valve.Automatic control pressure vent mainly is applicable on pipeline that industrial media is water, is used for getting rid of fast the gas in pipeline,, with efficiency and the unlikely deformation fracture of protection pipeline that improves pipe water, is the equipment of the indispensability of pipeline.
In existing water-carriage system, approximately contain 2% dissolved air in water, these air constantly are released in the water delivery process, and be gathered in the height point place of pipeline, form air bag, make the water delivery difficulty that becomes, cause the conveyance power of water of pipe-line system can therefore descend approximately 5%~15%.For these reasons, design a kind of performance better, the automatic control pressure vent that production and application is easier, play an important role to the filtration system of water and pipeline protection.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of automatic control pressure vent, and this automatic control pressure vent not only can be got rid of the gas in pipeline, and the timely interior air pressure of equalizing main, and effectively prevents from leaking.
For achieving the above object, the utility model provides following technological scheme:
A kind of automatic control pressure vent, comprise valve body, the bottom of described valve body is provided with the linkage structure that is connected for pipeline, the top of valve body is provided with exhaust port, be provided with the Spring balanced device for the equalizing main internal pressure in described valve body, described Spring balanced device comprises spring and ball float plug, and the lower end of described spring is fixedly mounted in described valve body, and described ball float plug is placed on the free end of described spring.
Further, described ball float plug comprises the ball float that split arranges and the chock plug that coordinates with described exhaust port, and described ball float and chock plug are placed on the free end of described spring from the bottom up successively.
Further, described valve body comprises upper valve body and lower valve body, airtight connection between described upper valve body and lower valve body, and described linkage structure is arranged on described lower valve body, and described exhaust port is arranged on described upper valve body.
Further, be provided with boss in described lower valve body, the lower end of described spring is fixedly mounted on described boss.
Further, described linkage structure is the connecting head that is arranged on described lower valve body, and described connecting head is provided with outside thread.
Further, described spring is stainless steel spring.
Further, described ball float plug separates with described exhaust port under free state.
The beneficial effects of the utility model are:
Automatic control pressure vent of the present utility model, exhaust port is in normally open, and by the Spring balanced device is set, when gas in pipelines was drained, current entered in outlet valve, and the ball float plug is at the effect float downward of buoyancy, and blocks exhaust port, prevents from leaking; When running well, if the gas of concentrating in valve body to a certain extent, the water level in outlet valve descends when pipeline, and the ball float plug descends thereupon, and exhaust port is opened, and gas is discharged from pore; If water pump stops, can producing negative pressure at any time in pipeline, the ball float plug descends at any time, carries out air-breathingly in a large number,, with the pressure in equalizing main, guarantees pipeline safety.
