Abstract
Pry open formula valve plug air relief valve, valve plug in casing, floater, connecting rod, disk seat and disk seat, the disk seat is fixed on the casing, and the valve plug rear end has a spring to exert the power of closing of valve port to the valve plug, and the connecting rod rear end is connected with the floater and is connect, and a quarter butt is fixed to its characterized in that valve plug rear end, and a support is fixed to the disk seat rear end, and the front portion of connecting rod hinges on the support, and the preceding end of connecting rod lies in the below of valve plug rear end quarter butt. The utility model discloses the articulated shaft location of connecting rod on by the support, the ascending power of prizing is applyed to the quarter butt of the front end cephalad valve plug of connecting rod when the floater moves down to the pressure that makes the valve plug overcome the spring is pried open from the valve port. The utility model discloses with rod positioning, the motion of orientation about the connecting rod can not produce, the floater is also limited by end before the connecting rod to the undue action of top to stop the production of other direction malfunctions of connecting rod, guaranteed the quality of product.
Description
Technical field
This utility model relates to automatic exhaust steam valve.
Background technology
Have the air bleeding valve of a kind of valve plug breaking-type structure at present for reducing volume, connecting rod is directly connected with valve plug rear end, and the other end of connecting rod is connected with ball float, by connecting rod, valve plug is broken into two with one's hands or is closed from valve port when ball float moves up and down.This structural linkages diameter is relatively thin and needs to reserve enough spaces to connecting rod; to ensure that valve plug can be broken into two with one's hands by connecting rod from valve port, but also it has been with a problem, it is simply that connecting rod range of activity greatly easily produces the motion of deviation duty simultaneously; usually can produce misoperation, cause leakage accident.
Summary of the invention
It is accurate that the purpose of this utility model is in that to provide a kind of valve plug to open or close action, the automatic exhaust steam valve of misoperation will not be produced, as shown in drawings, pry open formula valve plug automatic exhaust steam valve, including housing, ball float, connecting rod, valve plug in valve seat and valve seat, valve seat is fixed on housing, valve plug rear end has a spring to apply the closing forces of valve port to valve plug, rod rear end is connected with ball float and connects, it is characterized in that a quarter butt is fixed in valve plug rear end, a support is fixed in valve seat rear end, the front portion of connecting rod is hinged on support, the front end of connecting rod is positioned at the lower section of valve plug rear end quarter butt.This utility model connecting rod by support jointed shaft position, when ball float moves down quarter butt from the front end of connecting rod to valve plug apply one upwards prize power so that the pressure that valve plug overcomes spring is pried open from valve port, valve enter aerofluxus duty.Connecting rod is positioned by this utility model, and connecting rod will not produce the motion of left and right directions, and ball float excessive movement upward is also limited by connecting rod front end, thus having stopped the generation of other direction misoperations of connecting rod, valve will not leak, it is ensured that the quality of product.
Accompanying drawing explanation
Detailed description of the invention of the present utility model is provided below in conjunction with accompanying drawing.
Accompanying drawing 1 is this utility model front view.
In figure: 1, valve seat, 2, valve plug, 3, spring, 4, quarter butt, 5, connecting rod front end, 6, support, 7, jointed shaft, 8, connecting rod, 9, housing, 10, ball float.
Detailed description of the invention
A support 6 is fixed in valve seat 1 rear end, and valve plug 2 rear end quarter butt 4 is positioned at support 6, and connecting rod 8 is made of plastics, the front portion of connecting rod 8 is hinged on the frame 6 by jointed shaft 7, connecting rod 8 rear portion is connected with ball float 10, and the front end 5 of connecting rod 8 makes flat, and front end 5 is positioned at the lower section of valve plug 1 rear end quarter butt 4.When ball float 10 moves down, connecting rod 8 front end 5 applies a power upwards to quarter butt 4, is pried open by valve plug 2 from valve port.
