Abstract
The utility model discloses a small-sized automatic exhaust valve sealed by spring auxiliary force. A valve seat is arranged in a shell horizontally; a valve plug moves horizontally in the cavity of the valve seat, and the front end surface of the valve plug is opened or plugs a valve port; and a float ball is hinged with the valve plug through a connecting rod. The small-sized automatic exhaust valve is characterized in that a gland is fixed at the rear end of the valve seat, and an auxiliary spring is arranged between the gland and the rear end of the valve plug. When a floater floats up, thrust generated by the auxiliary spring and thrust generated by the floater form a resultant force which is then exerted onto the valve plug, thus increasing the sealing force of the valve plug on the valve port and improving the sealing effect of the valve plug on the valve port. In the utility model, the limited space in the shell is fully utilized and the sealing effect of the valve port is improved by adopting effective measures; and the small-sized automatic exhaust valve has simple structure and is convenient to be manufactured.
Description
Technical field
The utility model belongs to the heating system automatic control pressure vent.
Background technique
Small-sized automatic control pressure vent is widely used in heating system owing to have advantages such as volume is little, easy for installation.Because the float volume of small-sized outlet valve is restricted, the buoyancy of generation is less, and then the seal action power that is applied on the valve plug is just less, the situation that regular meeting is not closed completely.
Summary of the invention
The purpose of this utility model is to provide a kind of small-sized automatic control pressure vent with the spring assist sealing, to solve the problem that prior art exists, the technical solution of the utility model as shown in drawings, comprise the housing of forming by last lower shell body, last lower shell body is threaded, valve seat is horizontally disposed with in housing, valve plug moves horizontally its front-end face and opens or block valve port in the valve pocket of valve seat, ball float is hinged by connecting rod and valve plug, a gland is fixed in the rear end that it is characterized in that valve seat, and a power assistant spring is arranged between gland and valve plug rear end.During the float come-up, the thrust that power assistant spring and float produce forms to be made a concerted effort to be applied on the valve plug, has strengthened the sealing force of valve plug to valve port, has improved the sealing effect of valve plug to valve port.The utility model makes full use of the confined space in the housing, and adopting an effective measure has increased the sealing effect of valve port, simple in structure, easily manufactured.
