Abstract
The utility model discloses a ball-blocking type air release valve which comprises a valve body, wherein a valve cap and a fixed seat are connected on the valve body. A cylinder is connected on the fixed seat through a fixed piece, and a blocking ball is s arranged in the cylinder in a sliding way. A through hole is arranged on the valve body, and the valve body is communicated with the valve cap. A pull rod is arranged on the valve cap, a through hole is arranged at the center of the pull rod, and a tension spring is arranged in the through hole. The lower end of the tension spring is connected with the blocking ball, and the rear part of the lower end of the through hole on the valve body is provided with a sealing ring. An annular gasket is arranged between the valve body and the valve cap, and the sealing ring is fixedly arranged on the annular gasket. The ball-blocking type air release valve has simple structure, convenience for use and good sealing performance.
Description
Technical field
The utility model relates to valve field, and concrete is the stifled formula outlet valve of a kind of ball.
Background technique
Outlet valve is applied to pipeline exhausts such as independent heating system, central heating system, heating boiler, central air-conditioner, floor heating and solar heating system.Because all be dissolved with certain air in the water usually; And the solubility of air reduces along with the rising of temperature, and water gas in the circuit process is separated from water gradually like this, and gets together gradually and form big bubble even gas column; Because replenishing of water arranged, so often there is gas to produce.
Summary of the invention
The utility model provides a kind of easy to use, good seal performance, the stifled formula outlet valve of ball simple in structure.
The technological scheme of the utility model:
Ball blocks up the formula outlet valve, comprises valve body, connects valve gap on the valve body, it is characterized in that: in the described valve body fixed base is installed, is connected with a drum through fixed block on the described fixed base, the drum side bottom is provided with through hole, and its slides within is equipped with stifled ball; Described valve body is provided with through hole and is communicated with described valve gap; Described valve gap is provided with pull bar, and described pull bar central authorities are through hole, are provided with extension spring in the through hole; Described extension spring lower end connects described stifled ball, and the rear portion, through hole lower end on the described valve body is provided with seal ring.
Described ball blocks up the formula outlet valve, it is characterized in that: be provided with annular gasket between described valve body and the valve gap, described seal ring is fixedly mounted on the described annular gasket.
The advantage of the utility model:
The utility model is simple in structure, and is easy to use, good seal performance.
