Abstract
The utility model discloses a conical prism automatic gas exhaust valve. The inner wall of a casing is fixed with a supporting seat, the upper part of the supporting seat is provided with an exhaust port communicated with an exhaust nozzle, the exhaust nozzle is provided with a press plate, the press plate is provided with a sliding slot, the bottom of the supporting seat is provided with a supporting frame, and the lower part of the ball handle of a floating ball is hinged with the supporting frame. The conical prism automatic gas exhaust valve is characterized in that an upper casing and a lower casing are conical prisms, the position of the upper casing provided with the exhaust nozzle is a vertical surface, the floating ball is in hemispherical shape, and the bottom of the ball handle is fixed in the floating ball. The conical prism automatic gas exhaust valve has simple structure, small volume, easy installation and space saving. Cone saves materials, the prisms increase the pressure resisting capability of the valve, and the valve has compact internal structure and beautiful appearance.
Description
Technical field
The utility model belongs to the exhaust valve that heating, air-conditioning system are used.
Background technique
The pipeline of heating system all is to put by wall paper, and exhaust steam valve generally all is installed in the corner.Existing exhaust steam valve volume is bigger, and extreme length can reach 200 millimeters, and it is bigger to take up space, and inconvenience is installed in the corner, and not attractive in appearance.
Summary of the invention
The automatic exhaust valve that provides a kind of volume little is provided the purpose of this utility model, as shown in drawings, the utility model comprises the housing of being made up of upper shell and lower shell body, inner walls is fixed a bearing that is connected as a single entity with the steam discharge mouth, a steam-expelling port that communicates with the steam discharge mouth is arranged at bearing top, there is one to be used to the pressing plate that seals and open on the steam-expelling port, there is a stage clip to be pressed on the pressing plate on the bearing, chute is arranged on the pressing plate, rest base has a support, and the ball handle bottom and the support of ball float are hinged, and the top of ball handle is the cross bar shape, the bottom chute of the termination of cross bar and pressing plate is hinged, it is characterized in that, lower shell body is a taper rib body, and it is vertical surface that upper shell is installed steam discharge mouth position, and the ball float of the light body material of chemical industry becomes hemisphere, ball handle bottom is fixed in the floating ball body, and is in an acute angle under steam discharge mouth axis and the horizontal alignment.When in the valve body when anhydrous, the valve ball center of gravity moves down, and ball handle pulling pressing plate draws back pressing plate from steam-expelling port, and valve is in opening state, carries out steam discharge.When being full of water in the housing, move on the valve ball, the ball handle drives pressing plate and moves, and pushes pressing plate to steam-expelling port, and pressing plate cuts out steam-expelling port under the effect of stage clip and hydraulic pressure.The utility model is simple in structure, and volume is little, only is 1/4th or 1/3rd of existing exhaust steam valve, and is easy for installation, saves the space.The taper economical with materials, the rib body has increased the anti-pressure ability of valve, and the valve internal compact structure, and profile has aesthetic feeling.
Description of drawings
Accompanying drawing 1 is the utility model structure sectional view, and steam-expelling port is in opening state among the figure;
Among the figure: 1, steam discharge mouth; 2, steam-expelling port; 3, pressing plate; 4, chute; 5, ball handle; 6, upper shell; 7, ball float; 8, lower shell body; 9, stage clip.
Embodiment
Housing is made of metal, and is eight rib bodies, and the Octagon length of side is 21 millimeters above the upper shell, below 26 millimeters of the length of sides, 39 millimeters of upper casing heights, upper and lower shell body and function screw is connected to an integral body, the connection screw socket is arranged at the lower shell body bottom.Ball float is made by polyurethane material, and the ball handle is made of plastics, and during the moulding of polyurethane ball float ball handle bottom is embedded in the spheroid.
