Abstract
Connecting rod four directions is to spacing metal casing air bleeding valve, by last, the inferior valve body group becomes, the disk seat comprises with the back valve pocket the preceding valve pocket of taking the exhaust nozzle, it is preceding, back valve pocket threaded connection fixes at last casing, the valve plug is arranged in the valve pocket, the disk seat is pressed on the valve nozzle through the spring of its rear end, the connecting rod of valve plug rear end is pegged graft with the floater upper end in the casing through the connecting rod export of back valve pocket rear end, the connecting rod export of valve pocket is the convex bar mouth in upper end behind its characterized in that, the radius of circular arc is the same with the radius of connecting rod, be equipped with a summit on the floater. After adopting this structure, the floater raises the valve plug presses when the valve nozzle, and the direction receives unable removal of restriction of bar mouth about the connecting rod, and reciprocating of connecting rod has also been restricted on the summit, thereby has avoided the floater to receive impurity to influence the drive connecting rod swing and caused the valve plug to break into two with one's hands and the accident of leaking that appears from the valve nozzle.
Description
Technical field
The utility model belongs to heating system drain tap, particularly relates to metal shell spring structure outlet valve.
Background technique
There is the vertical outlet valve of a kind of metal shell at present, be made up of upper and lower casing, upper and lower casing outside nut connects, and valve seat is fixed on upper shell, valve plug in valve seat is pressed on valve nozzle by the spring of its rear end, the ball float upper end grafting in the connecting rod of valve plug rear end and housing.The outlet valve of this structure has that structure is simple, volume is little, close feature flexibly, but because the connecting rod outlet of valve seat rear end is a circular port, connecting rod front end is positioned at this circular port, when valve nozzle is closed, connecting rod is in the center of circular port, connecting rod has the activity space of four direction up and down, when ball float can swing by drivening rod when four direction swings up and down by impurity effect in housing, thus valve plug is broken into two with one's hands from valve nozzle, valve is in open mode, causes leakage accident.
Model utility content
The purpose of this utility model is to provide one to have the spacing metal shell outlet valve in connecting rod four direction, the state that when making valve plug be in closed condition, connecting rod keeps a kind of four direction spacing, technological scheme as shown in Figure 1, the spacing metal shell outlet valve in connecting rod four direction, by upper, lower shell body forms, on, lower shell body is connected by outside nut, valve seat is made up of the front valve pocket with exhaust nozzle and rear valve pocket, front and back valve pocket is threaded and is fixed on upper shell, valve plug is placed in valve pocket, valve seat is pressed on valve nozzle by the spring of its rear end, the connecting rod of valve plug rear end is by the connecting rod outlet of rear valve pocket rear end and the ball float upper end grafting in housing, it is characterized in that the connecting rod outlet of rear valve pocket is strip shape gob, the upper end of strip shape gob is circular arc, the radius of circular arc is identical with the radius of connecting rod, relative to being provided with a summit in the middle part of connecting rod on ball float.After adopting this structure, when ball float rise valve plug is pressed in valve nozzle, connecting rod front end is positioned at strip shape gob top, the restriction that its left and right directions is subject to strip shape gob cannot be moved, summit also limit moving up and down of connecting rod, make connecting rod close four direction up and down at valve nozzle limited, avoid ball float and swing by impurity effect drivening rod thus the leakage accident causing valve plug to depart from valve nozzle and occur.
Accompanying drawing explanation
Embodiment of the present utility model is provided below in conjunction with accompanying drawing.
Accompanying drawing 1 is the utility model sectional view.
Accompanying drawing 2 is valve pocket structure one plan view after the utility model figure.
Accompanying drawing 3 is valve pocket structure two plan view after the utility model figure.
Accompanying drawing 4 is the novel rear valve pocket sectional view of this implementation.
Legend: 1, rear valve pocket, 2, connecting rod outlet, 3, connecting rod, 4, summit.
Embodiment
Upper and lower casing is irony, linked together by the several screw screws on shell border, forward and backward valve pocket is copper, forward and backward valve pocket is fixed on inside and outside upper shell by screw thread, front valve pocket is positioned at outside housing, rear valve pocket is positioned at housing, steel connecting rod 3 is fixed on the rear end of valve plug, a spring top applies elastic force in the rear end of valve plug to valve plug makes valve plug be pressed on valve nozzle, the rear end of connecting rod is inserted in the hole of ball float upper end, summit 4 on ball float is square, and the connecting rod of rear valve pocket 1 outlet 2 is the consistent long strip of upper and lower width, sees accompanying drawing 2.
It is gradually wide fan-shaped that the connecting rod outlet 2 of rear valve pocket 1 also can be downward A/F, sees accompanying drawing 3.
Claims (3)
