Coordinate so that when spool 3 activity is to certain position, tap hole 21 can be closed so that liquid cannot flow out valve body 1.Spool drives
Motivation structure includes valve rod 4, lower cylinder, upper cylinder and adjusting nut set 68, and described lower cylinder includes lower cylinder body 61, therapeutic method to keep the adverse QI flowing downwards bar 62
And lower piston 63, described upper cylinder includes on upper cylinder body 64, first gas bar 65, upper piston 67, described valve on gas bar 65, second
The lower end of bar 4 is fixed on spool 3, and the upper end of described valve rod 4 is fixed on the lower end of therapeutic method to keep the adverse QI flowing downwards bar 62, and the upper end of therapeutic method to keep the adverse QI flowing downwards bar 62 is fixed
In the lower end of lower piston 63, lower piston 63 is slidably mounted in lower cylinder body 61, and upper cylinder body 64 is fixed on lower cylinder body 61, and described
On one, the upper end of gas bar 65 is fixed on the lower end of upper piston 67, and on second, the lower end of gas bar 65 is fixed on the upper end of upper piston 67,
Offer external screw thread on second on gas bar 65, adjusting nut set 68 offers internal thread hole, internal thread hole and external screw thread and passes through
Threaded engagement so that adjusting nut set 68 is screwed on second on gas bar 65, adjusting nut set 68 is positioned at the top of upper cylinder, upper work
Plug 67 is slidably mounted in upper cylinder body 64, and the upper end of lower cylinder body 61 offers and is available for gas bar 65 on first and inserts time cylinder from top to down
Penetrating hole in body 61, valve body 1 offers the inserted link hole 13 inserting in valve body 1 for valve rod 4, described inserted link hole 13 is positioned at
The top of material mouth 12.In the present embodiment, the stable distance that spool drive mechanism is possible not only to control between spool 3 and valve port 2 exists
States different in three, such that it is able to reach the effect that runner equivalent area is different, thus realize quickly, at a slow speed, close three kinds
Bottling condition, and adjusting nut can be changed overlap the position of 68 relative second gas bars, regulation by rotating adjusting nut set 68
Filling valve runner size between valve port 2 and spool 3, such that it is able to regulate filling speed at a slow speed easily, specific works principle
As follows, A) realize quickly, at a slow speed, close the principle of three kinds of bottling condition: in the present embodiment, spool drive mechanism can be with control valve
The state that stable distance between core 3 and valve port 2 is different in three, such that it is able to reach the effect that runner equivalent area is different,
Thus realize quickly, at a slow speed, close three kinds of bottling condition, concrete principle is as follows: the 1) therapeutic method to keep the adverse QI flowing downwards bar 62 of lower cylinder and upper cylinder
Upper gas bar all in retracted mode time, valve rod 4 band movable valve plug 3 moves upwardly together, and makes spool 3 closely cooperate with valve port 2, this
Time filling valve be closed, as shown in Figure 1.2) it is in the state of stretching out, valve rod 4 band movable valve plug when the therapeutic method to keep the adverse QI flowing downwards bar 62 of lower cylinder
3 move downwardly together, and now spool 3 separates with valve port 2 and both gaps are in maximum rating, and now logistics is entered from feeding mouth 11
Entering in the valve pocket of valve body 1, the runner between spool 3 and valve port 2 flows out.Now filling valve is in Quick-filling state, as
Shown in Fig. 2.3) it is in fully extended state when the upper gas bar of upper cylinder so that the upper gas bar of upper cylinder inserts lower cylinder from top to down
In body 61, block moving up of lower piston 63, so that the therapeutic method to keep the adverse QI flowing downwards bar 62 of lower cylinder can not be fully retracted, but in being parked in
Between position.Now spool 3 and spool 3 and not in contact with but the gap of runner reduce, now fill valve port 2 equivalent area reduces, and fills
Dress valve is in bottling condition at a slow speed, as shown in Figure 3.B) principle of filling valve runner size of bottling condition at a slow speed is quickly regulated such as
Under: during fill, lower cylinder band ovable valve stem 4 moves downward, and valve rod 4 band movable valve plug 3 moves downwardly together, spool 3 and valve port 2 points
From, filling valve is in open mode, and now, material passes into the valve pocket of valve body 1 from charging aperture, finally from spool 3 and valve port 2
Between gap (i.e. filling valve runner) in flow out.Distance dependent between filling valve runner size and spool 3 and valve port 2, valve
The distance that core 3 moves downward is the most remote, and the gap formed between itself and valve port 2 is the biggest, and the equivalent bore of filling valve is the biggest.Upper
During on the second of cylinder, gas bar 65 moves down, the lower end of adjusting nut set 68 withstands on upper cylinder body 64, gas bar 65 on second
Stopping moves down, and upper piston 67 stops moving down, and overlaps the position of gas bar 65, i.e. adjustable on 68 relative second by changing adjusting nut
The upper gas bar of upper cylinder rests on the height in lower cylinder body 61, thus limits the height that piston is upwards movable, so that the therapeutic method to keep the adverse QI flowing downwards
First therapeutic method to keep the adverse QI flowing downwards bar 62 of cylinder can not be fully retracted, but is parked in centre position, i.e. scalable filling valve open mode bottom spool 3 to
The distance of lower motion.As Fig. 4 be exactly change adjusting nut set 68 position, now filling valve under bottling condition at a slow speed etc.
Effect bore is less than shown in Fig. 3 equivalent bore during bottling condition at a slow speed.To sum up, by changing the position of adjusting nut set 68,
The fill bore of filling valve can be regulated the most easily, such that it is able to be adapted to the fill requirement of obstructed viscosity coating.
In the present embodiment, described tap hole 21 is truncated cone-shaped hole, described spool 3 in truncated cone-shaped, tap hole 21 and spool 3
Tapering is identical, and the axis of tap hole 21 and the axis collinear of spool 3 are arranged.The design of the present embodiment tap hole 21 and truncated cone-shaped with
And fit structure each other, it is adaptable to the paint filling of various viscositys, can effectively solve the splash during paint filling
And dripping problems, concrete principle is as follows: material passes into the valve pocket of valve body 1 from charging aperture, finally from spool 3 and valve port 2 it
Between gap in flow out, as it is shown in figure 5, due to runner ringwise, and due to fluid upper and lower surface respectively with the tap hole of valve port 2
21 internal faces contact with the outside wall surface of spool 3, and its wetting areas is big, and Reynolds number is relatively big, and therefore the flow regime of logistics is rendered as
Laminar flow, thus avoid the expulsion events caused because of turbulent flow, meanwhile, material flows downward along round table surface, material and spool 3
Bottom surface is not in contact with, and therefore when filling valve is closed, as shown in Figure 6, spool 3 is upwards transported under the drive of spool drive mechanism
Dynamic, spool 3 closely cooperates with valve port 2, completes sealing and the closedown of filling valve.Owing to spool 3 bottom surface does not has contacting material, because of
There is not the dripping problems of salvage stores in this filling valve, thus fundamentally avoids fill weeping after closing.
In the present embodiment, the discharging opening 12 of described valve port 2 and valve body 1 is connected by Quick hoop 7.
In the present embodiment, the lower end of described valve rod 4 offers threaded connection hole, described spool 3 offers spool 3 and connects
Hole, a connecting bolt 8 penetrates spool 3 connecting hole and is threaded into connecting hole, thus being fixed on valve rod 4 by spool 3.
