Abstract
The utility model relates to a Float hall type ball-shaped check valve composed of a valve body, a valve seat, ball nests, a valve cover, a glue ball, a ball core, arced racks, etc. Two arced racks and ball nests are arranged in the float hall type ball-shaped check valve. When opened, the glue balls are pushed by medium pressure to enter the ball nests along the arced racks, so medium flow resistance is small; when closed, the closed pressure of a water hammer can be automatically decreased. The main function of the float hall type ball-shaped check valve is to prevent media in a pipeline from flowing back. The float hall type ball-shaped check valve automatically open or close by medium pressure, and is especially suitable in a water feeding pipeline.
Description
The utility model relate to a kind of little for flow resistance, close that water hammer pressure is little, the float-ball type ball check valves.
This valve is by being loaded in the delivery (pipe) line, it mainly acts on: prevent that the pipeline medium from flowing backwards, it is to open automatically or close by pressure medium, glueballs is subjected to the promotion of pressure medium to enter the ball nest along the arc track when establishing two arc tracks, ball nest, unlatching in the valve body, makes the pressure that the medium flow resistance is little, can reduce to close water hammer when closing automatically.
Existing ball check valve door, because the non-return glueballs of its valve is positioned at the metering orifice center, it is bigger to produce flow resistance, produce bigger water hammer pressure when opening or closing, this valve glueballs is a straight line motion, and impact force is big, destroys glueballs often, cause sealing poor, serious jumping ball in addition, card ball phenomenon.
The purpose of this utility model so be to provide a kind of flow resistance little, close that water hammer pressure is little, the float-ball type ball check valve door of good seal performance, long service life.
Below in conjunction with accompanying drawing technical solution of the present utility model is described:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is I among Fig. 1-I position sectional view.
The sequence number of marking is expressed as follows respectively in the accompanying drawing:
1, valve body; 2, valve seat; 3, ball nest; 4, valve gap; 5, glueballs; 6, ball core; 7, arc track.
The float-ball type ball check valve door of forming by valve body, valve seat, ball nest, valve gap, glueballs, ball core, arc track etc.
Its valve seat 2 is connected with valve body 1; Valve gap 4 links to each other with valve body 1 upper flange Connect; In arc track 7 bottoms and the valve body 1, the water inlet is connected; The arc road Rail 7 tops are interior with valve body 1 upper flange, the bottom is connected; Ball core 6 and glueballs 5 Be connected; Ball nest 3 is positioned at valve gap 4 bottoms; Glueballs 5 is positioned at arc track 7.
In order to make the valve flow resistance little, in valve body 1, establish two arc tracks 7, Glueballs 5 is subjected to the promotion of pressure medium to enter ball nest 3, medium along making arc track 7 Pressure is held out the flow center with glueballs, thereby makes the medium flow resistance little. Open or close The time glueballs along making the track arcuate movement, extenuated impulsive force, make glueballs not fragile, Increase the service life.
The advantage of this float-ball type ball check valve door just is to have adopted in the valve body arc track, ball nest, and pressure medium is held out the flow center with glueballs and reduced flow resistance; Glueballs has been extenuated impact force by arcuate movement when closing, and has reduced to close water hammer pressure automatically simultaneously, and prolong its working life greatly.
Embodiment:
DN80mm, nominal pressure 1.0MPa
Valve body 1, valve seat 2, valve gap 4, arc track 7 adopt gray cast iron to make, and after ball core 6 adopted the steel plate punching press to make, outpacking rubber was pressed into glueballs 5.
Claims (2)
1, float-ball type ball check valve door is made up of valve body, valve seat, ball nest, valve gap, glueballs, ball core, arc track etc., it is characterized in that: this float-ball type ball check valve door; Establish in two arc tracks (7) bottom and the valve body (1) in the valve body (1), the water inlet is connected; In arc track (7) top and valve body (1) upper flange, the bottom is connected; Valve seat (2) is connected with valve body (1); Valve gap (4) is connected with valve body (1) upper flange; Glueballs (5) is positioned at arc track (7).
