Abstract
The utility model discloses a ball-type exhaust valve with high intensity. A fixing seat is installed in a valve body, a round drum is fixed on the fixing seat, and a blocking ball is installed in the round drum in a sliding mode. A spring is placed between the blocking ball and the bottom of the round drum, a sealing layer is covered on the outer side of the blocking ball, and a pulling rod is arranged on a valve cover. A through hole is arranged in the center of the pulling rod, a tension spring is arranged in the through hole, and the blocking ball is connected with the lower end of the tension spring. A strengthening rib is connected between the pulling rod and the valve cover, and a sealing ring is arranged on the back portion of the lower end of the through hole in the valve body. According to the ball-type exhaust valve with the high intensity, the strengthening rib is added between the pulling rod and the valve cover, so that endurance intensity of the exhaust valve is improved, and failure of the exhaust valve caused by breakage of the pulling rod when the exhaust valve is used is prevented. The ball-type exhaust valve with the high intensity is simple in structure, convenient to use, good in sealing performance and capable of prolonging the service life.
Description
Technical field
The utility model relates to valve technology field, relates in particular to the large ball formula outlet valve of a kind of intensity.
Background technique
Outlet valve is applied to the pipeline air exhaust waters such as independent heating system, central heating system, heating boiler, central air-conditioner, floor heating and solar heating system.Because usually all be dissolved with certain air in water, and the solubility of air reduces along with the rising of temperature, and water gas in the process of circulation is separated from water gradually like this, and gets together gradually and form even gas column of large bubble, because replenishing of water arranged, so γ-ray emission is often arranged.The outlet valve of prior art relates to unreasonable, poor sealing, and easily fracture, and physical life is short, needs to improve.
The model utility content
The utility model purpose is exactly in order to make up the defective of prior art, to provide a kind of intensity large ball formula outlet valve.
The utility model is achieved through the following technical solutions:
the ball formula outlet valve that a kind of intensity is large, comprise valve body, connect valve gap on valve body, in described valve body, fixed base is installed, fix a drum on described fixed base, the drum slides within is equipped with stifled ball, be placed with spring between bottom described stifled ball and drum, the described stifled ball outside is coated with sealing layer, described valve body is provided with through hole and is communicated with described valve gap, described valve gap is provided with pull bar, described pull bar central authorities are through hole, be provided with extension spring in through hole, described extension spring lower end connects described stifled ball, be connected with stiffening rib between described pull bar and valve gap, rear portion, through hole lower end on described valve body is provided with seal ring.
Be provided with annular gasket between described valve body and valve gap, described seal ring is fixedly mounted on described annular gasket.
The utility model has the advantages that: the utility model increases the endurance strength of outlet valve by increasing the stiffening rib between pull bar and valve gap, prevents that outlet valve in use, the pull bar fracture causes outlet valve to be scrapped, and is simple in structure, easy to use, good airproof performance has extended working life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
