Specific implementation mode
The structure and utility model of the bars,folding parallel bar micro-exhaust valve of the utility model are described with reference to Fig. 1 to 4
Content.
A kind of bars,folding parallel bar micro-exhaust valve, including valve body 1, be set to 1 upper end of valve body valve deck 2, be mounted on valve
Valve component 3 on lid 2, the first lever 4 being arranged inside valve body 1 and the second lever 5, the floating ball 6 being connect with the first lever 4
And the sealing element 7 on 5 on the second lever with the sealing cooperation of valve component 3 is set.
The valve body 1 is equipped with valve port 11, can for liquid or gas passes through.
The valve deck 2 is equipped with the mounting hole 23 installed for valve component 3.The top of the mounting hole 23 is equipped with interior spiral shell
Line.Valve deck 2 is fixed on by several screws on valve body 1, and the on-line maintenance of valve inner part may be implemented.
The valve component 3 includes valve seat 31, the seal receptacle 32 being wrapped in outside valve seat 31 and is arranged above valve seat 31
Gland 33.The cross section of the valve seat 31 and seal receptacle 32 is T fonts, and is equipped in T fonts bottom and matches with sealing element
The horn mouth of conjunction.The valve seat 31 and seal receptacle 32 are mounted in mounting hole 23.The gland 33 is by valve seat 31 and seal receptacle 32
It compresses, and is connect with the internal thread of mounting hole 23.Valve seat 31 is internally provided with through-hole 311.The gland 33 is internally provided with and through-hole
The Vertical Channel 331 of 311 connections and horizontal channel 332.The horizontal channel 332 runs through 33 both sides of gland and forms two exhausts
Hole, gas can pass sequentially through except 332 exits valve body 1 of through-hole 311, Vertical Channel 331 and horizontal channel.
One end of first lever 4 is hinged to form the first hinge joint 21 with valve deck 2, and is equipped with the in the axial direction
One slideway 41 and the second slideway 42.The midpoint of first slideway 41 is less than the midpoint of the second slideway 42 to the distance of the first hinge joint 21
To the distance of the first hinge joint 21.
Second lever 5 includes the first plate portion 51 and the second plate portion 52 being mutually parallel, during the first lever 4 is clipped in
Between, the installation space of lever assembly is greatly had compressed, valve volume is reduced.It uses one end of first plate portion 51 and the second plate portion 52
First screw 8 is fixed on valve deck 2, forms the second hinge joint 22；The other end is slidably mounted on the first cunning by the second screw 9
In road 41.
The floating ball 6 is mounted on by screw on the second slideway 42, and can be slided in the second slideway, and floating ball is made to increase
Or it is always positioned at valve body center during declining, to compression valve volume.
The sealing element 7 is ball shape, and is fixed by screws between the first plate portion 51 and the second plate portion 52, can be with valve
The sealing cooperation of holder assembly 3.
The operation principle of the utility model：
When the air in pipeline enters valve, gas can be built up on the top in valve body 1, oppress water level decreasing, floating ball 6
Decline under the effect of gravity and the first lever 4 is driven to be rotated clockwise, the slide downward in the first slideway 41 of screw 9, by
It is less than the distance of the 6 to the first hinge joint of floating ball 21 in the distance of the 9 to the first hinge joint of screw 21, therefore the first lever 4 is by floating ball 6
Gravity for the first time amplify；Second lever 5 is rotated counterclockwise, and ball 7 is made to be detached with valve component 3, and micro exhaust outlet is beaten
It opens, since the distance of the 7 to the second hinge joint of ball 22 is less than the distance of the 9 to the second hinge joint of screw 22, the second lever 5 will
Second of the amplification of the gravity of floating ball 7.
When air drains, water flows into from valve port 11 and jacks up floating ball 6, and the first lever 4 rotates counterclockwise, and screw 9 is the
Upward sliding in one slideway 41, the second lever 5 rotate clockwise, ball 7 and valve component 3 are compressed, and the buoyancy of floating ball 6 passes through
More reliable sealing may be implemented in amplification twice.
On the other hand, the first lever 4 is arranged between the first plate portion 51 and the second plate portion 52, huge compression lever assembly
Installation space, reduce valve volume.
On the other hand, seal receptacle 32 is set outside valve seat 31, and the pressure of spherical sealed is born by hard valve seat 31, soft
The only a small amount of deformation of seal receptacle 32, even if valve frequently opens and closes, sealing element not will produce fatigue damage, improves valve and uses the longevity
Life；Ball 7 has the sealing characteristics of automatic capturing, and insensitive to installation accuracy, reduces failsafe valve rate.
