Accompanying drawing is the plan view of control aperture formula float valve when the use position that proposes according to the present invention, and utilizes to analyse and observe and represent its internal structure.Valve shown in the figure is in closed condition.
Describe details and the working condition that the present invention proposes concrete device in detail below in conjunction with accompanying drawing
As shown in drawings, the valve seat 3 of the stop valve part of this float valve has a pilot hole that cooperates with push rod 22 and is used for the garden wimble fraction of installation garden awl telescopic body 6, and a ventilative aperture 4 arranged, the space that front plate 5 and valve seat 3 are formed is in communication with the outside, the front tab 1 of valve seat 3 connects, and the rear end connects with bonnet 8.Plunger 2, push rod 22 all has endoporus.The endoporus of push rod 22 cooperates with the outer garden that is communicated with joint 18, and control chamber 16 is by rear plate 7, and garden awl telescopic body 6 is communicated with the space that joint 18 and bonnet 8 are formed.Being communicated with between hole 20 in the joint 18 and outlet aperture 13 and the little push rod 14 has very big gap, the endoporus of plunger 2 and push rod 22 be communicated with the hole of saving in 18 20 and hole 10,17 connections after, make control chamber 16 can experience the total pressure of plunger 2 endoporus front ends.The hole 10,17 and the hole 11,15 that are communicated with in the joint 18 are communicated with outlet aperture 13, are communicated with joint 18 and also have a hole that cooperates with little push rod 14, are communicated with joint 18 and are fixed on the bonnet 8.One end of little push rod 14 is embossed on the Sealing 12 of little latus rectum float valve, the other end is connected on the small plunger 21, the latus rectum of the diameter of small plunger 21 and outlet aperture 13 about equally, make and the inaccessible power that exports aperture 13 can boost small plunger 21 equally, garden awl telescopic body 6 is awl garden bodies made from soft material, its front end is fixed on the push rod 22 by front plate 5 and rear plate 7, and the rear end is fixed on the valve seat 3 by bonnet 8.It can easily make fore and aft motion with push rod 22, two position limit pins 9,19 are arranged on the rear plate 7, not blocked to guarantee the hole 10,18 that is communicated with on the joint 16, spring 23 is installed between the outer step and the interior step of housing of plunger 2, the effect of spring 23 is: when the valve that is in open mode, owing to lack of water or other reason make the inlet total pressure very little, thereby make the poor of the suffered total force of suffered total force of rear plate 7 and plunger 2 front surfaces, can not offset between push rod 22 and the pilot hole and endoporus be communicated with joint 18 outside
Between frictional force, make the valve can not be inaccessible, at this moment the power by spring overcomes the suffered frictional force of guide rod, makes valve inaccessible smoothly because the effect of spring 23 only is in order to overcome the suffered frictional force of push rod, so
Make softer.The selection principle of control chamber 16 diameters: the valve that is in open mode, export aperture 13 this moment by inaccessible, aperture 20 is opened, the maximum static pressure that can experience in the control chamber 16 is exactly by force the total pressure of plunger 2 endoporus front ends, in fact if the area of rear plate 7 multiply by the total pressure of plunger 2 endoporus front ends can be greater than the suffered total force of plunger 2 front surfaces, at this moment relending the power that helps spring 23 just can be successfully the valve obturation, and the area of the smallest end cross-section area of control chamber 16 and rear plate 7 is about equally.Just can draw the required cross-section area of smallest end of control chamber 16 at an easy rate according to above-mentioned explanation, its diameter is also fixed thereupon like this.Need to prove: the total pressure of plunger 2 endoporus front ends recited above and the suffered total force of plunger 2 front surfaces are meant that all valve is in open mode.The Sealing 12 of the little latus rectum float valve part of this float valve is glanded 25 and is fastened on the housing 24 through gland nut 29, sliding bar 26 can slide at the endoporus of gland 25, lever 27 can scratched bearing pin 28 along with upper and lower the floating of ball float 30 and done corresponding the rotation, and drive sliding bar 26 slides, sliding bar 26 promotes the intermediate portion motion of Sealing 12 again, thereby realizes flowing out the control of aperture 13.
The course of action of valve:
Be in the valve of closed condition, when the drawdown in the water tank, be that ball float is floated downward, sliding bar 26 retreats, and flows out aperture 13 and is opened, and aperture 20 is simultaneously by inaccessible, at this moment the water in the control chamber 16 is through the hole 10, and hole 11,15, flowing out by flowing out aperture 13, the pressure in the control chamber 16 reduces rapidly, at this moment, plunger 2 is done motion backward, i.e. valve open under the suffered active force effect of its front surface, be in the valve of open mode, after waterborne in the water tank is raised to a certain degree, flow out aperture 13 by inaccessible, aperture 20 is opened simultaneously.At this moment water will flow to control chamber 16 through aperture 20 and aperture 10,17, and the static pressure in the control chamber 16 is improved rapidly.Act on total force on the rear plate 7 at last and will promote plunger 2 and travel forward, it is to throttle down.Be in the valve of closed condition, as long as flowing out aperture 13 is not opened, be aperture 20 not by obturation so the suffered static pressure of plunger 2 front surfaces and rear plate will keep equating that and the area of rear plate 7 so just can make valve keep closing state greater than the surface of plunger 2.
