Internal.First valve closing first flow and second valve closing the second runner.Additionally, each valve
Door all has different springs, so each valve has current and needs the active force of the spring overcome.
But, this solution proposes to have a problem in that, it is impossible to adjust the active force of spring, although bag
Include the spring with two different active forces, but spring resistance is the most constant and can not increase or subtract
Little.
It is found that another technical solution of document US 5,411,053 statement of North America, describes
Having the pressure regulator of adjustable setting, actuator includes two screwed parts, according to two spiral shells
Distance between stricture of vagina parts, increases or reduces the mobile space of plunger.More precisely, attach to post
The spring in portion contacts with screwed part beyond the Great Wall, and the increase of the active force of spring or reduction depend on as
What disposes screwed part.Pressure regulator is also equipped with high-pressure outlet and low tension outlet.
But, this solution propose problem for suitably adjusting pressure regulator, two screw threads
Parts all must move, and this solution needs more to adjust the time, is unprofitable to the work of operator.
Therefore, do not have technically can to increase in a variable manner and reduce the active force of spring and
Close the runner pressure-regulating valve with regulated fluid flow.
Goal of the invention
Therefore, it is an object of the invention to, it is provided that one allows increase in a variable manner or reduce bullet
The pressure-regulating valve of the active force of spring.
It is a further object of the invention to provide a kind of fluid passage of closing with regulated fluid flow
Pressure-regulating valve.
It addition, it is a further object of the invention to provide one to guarantee that in aerosol apparatus flow is equal
Therefore even pressure-regulating valve, to better profit from the pressure from the fluid that will discharge, and subtract
The risk of few user uses.

Detailed description of the invention
Fig. 1 describes the preferred embodiment of the flow control valve of the present invention.Such as, pressure-regulating valve can
To be applied to aerosol apparatus, such as the bar of knapsack sprayer.
As shown in Figures 1 to 4, pressure-regulating valve 1 is provided with and includes the shell 2 of opening 21 and be screwed onto
The adjustment element 3 of the outer lower portion of shell 2.
There is piston 5 inside of shell 2, the central upper portion part of this piston is provided with regulating element 51,
This piston has the hole 52 being arranged on around regulating element 51 and is intended at piston 5 and shell 2
Between seal O 54.
As shown in Figure 3 and Figure 4, at the externally-arranged flexible member 6 of piston 5, wherein, elastic unit
First end of part 6 relies on piston 5.
When there is no fluid in by the top 53 of piston 5 and the chamber 8 being internally formed of shell 2,
Flexible member 6 all keeps regulating element 51 to contact with the opening 21 of shell 2.
The top of pad 7 relies on the second end of flexible member 6.As Fig. 3 preferably illustrates, pad
Sheet 7 is placed on the inside of inside subject 4 and relies on the bottom adjusting element 3.
Inside subject 4 is placed in the inside of piston 5, and this inside subject is provided with and is necessarily used for allowing
Passage 41 that fluid passes through and be intended between inside subject 4 and piston 5 O 42 sealed.
The fluid inside by inside subject 4, that is, flow through passage 41, arrival chamber 8
And through hole 52.For the fluid opening 21 by shell 2, the pressure within chamber 8 must hold
Active force by flexible member 6.
But, if the pressure within chamber 8 is much larger than the active force of flexible member 6, then regulation
Element 51 closing passage 41, until the pressure within chamber 8 declines, reopens the logical of passage 41
Road.When the pressure within chamber 8 is more than the active force of flexible member 6, just there are those steps.
Additionally, if the user desired that increase or reduce the resistance of flexible member 6, he must tighten tune
Whole element 3 is to increase resistance or to unscrew this adjustment element to reduce resistance.
When tightening adjustment element 3, pad 7 moves towards piston 5, therefore compression elastic element 6,
Thus increase resistance and increase makes regulating element 51 open the active force of the path to opening 21.
On the other hand, when unscrewing adjustment element 3, pad 7 moves away from piston 5, therefore reduces
The pressure of flexible member 6, therefore, reduces the resistance of this flexible member, makes regulating element 51 open out
The active force of mouth 21 dies down.
