Attached drawing, technical solutions in the embodiments of the present application is further described in more detail.
In the description of the present application, term " center ", " longitudinal direction ", " transverse direction ", "front", "rear", "left", "right", "vertical",
The orientation or positional relationship of the instructions such as "horizontal", "top", "bottom", "inner", "outside" is that orientation based on the figure or position are closed
System is merely for convenience of description the application and simplifies description, rather than the device or element of indication or suggestion meaning must have
Specific orientation is constructed and operated in a specific orientation, therefore should not be understood as the limitation to the application protection scope.
In order to solve in the prior art, for throttle valve in changes in flow rate, the problem of restriction effect difference, this application provides one
The constant throttle valve of kind rate of discharge.
The constant throttle valve of the rate of discharge of the application includes shell 1, pressure inlet 12, valve base 8, valve 9 and spring 5,
12 coaxial line of shell 1 and pressure inlet it is relatively fixed by screw thread, the outlet end and input end of shell 1 and pressure inlet 12 can pass through
Engagement thread is installed in the hydraulic system using the application, and valve 9, valve base 8 and spring 5 are set to shell 1 and pressure inlet
In 12 recirculation holes constituted, wherein valve 9 has circumferentially arranged first through hole 91, and the number of first through hole 91 is at least
One, may be set to be it is multiple, valve base 8 have circumferentially arranged the second through-hole 81 and third through-hole 82, the second through-hole
81 and the number of third through-hole 82 be equally at least one, may be set to be multiple, and the side wall of valve base 8 and recirculation hole has
There is the gap for fluid circulation, under rated condition, first through hole 91 is aligned and is connected to, valve base with 81 axis of the second through-hole
8 can slide under the action of spring 5 along the axis direction of recirculation hole, be connected to adjust first through hole 91 with the second through-hole 81
Area to control the flow in throttle valve.
In this application, the predetermined amount of flow of throttle valve can pass through first through hole 91, the second through-hole 81 and third through-hole 82
Via area and number determine.For example, expanding first through hole 91, the second through-hole 81 and third through-hole to expand metered flow
82 area, or increase first through hole 91, the quantity of the second through-hole 81 and third through-hole 82 circumferentially.
In this application, the elastic force that the predetermined amount of flow of throttle valve also passes through spring 5 determines.The elastic force of spring 5 is too small, flow
When (flow velocity) increases, spring 5 is easy to be compressed, therefore the size of metered flow can be controlled by the elastic force of spring 5.
In this application, the first strainer 10 is equipped between pressure inlet 12 and valve 9, for filtering the impurity in fluid.By
In the application, the gap between valve base 8 and the side wall of recirculation hole cannot circulate excessive particle, therefore use the first strainer
10 filterings in advance flow into the substance in gap.
In this application, the second strainer 2 is equipped between shell 1 and spring 5, for filtering the impurity in fluid.Due to this
In application, spring 5, valve base 8 need to move often, therefore can generate iron filings, and the second strainer 2 in the application can then filter
Iron filings prevent it from flowing into lower system.
In this application, it since spring 5 is metallics and is moved often, is equipped between spring 5 and the second strainer 2
Washer 3, for protecting the second strainer 2.
In this application, it is equipped with spring base 4 between spring 5 and washer 3, is used to support spring 5.
In this application, sealing ring is equipped between shell 1 and pressure inlet 12, for sealing.
In this application, first through hole 91 and circulation axially bored line can be at 60 degree to 120 degree angles, and and first through hole
91 the second through-holes 81 being used cooperatively with circulation axially bored line is same can be at 60 degree to 120 degree angles.
In this application, third through-hole 82 and circulation axially bored line are at 60 degree to 120 degree angles.
At work, hydraulic oil enters throttle valve by import to the constant throttle valve of the rate of discharge of the application, through filtering
Net 10 is by after impurity removal in oil liquid, and oil liquid is by the through-hole (throttle orifice) on valve 9 and valve base 8, using strainer 2, by
Outlet outflow.When flow increase between inlet and outlet, increased by the liquid in the gap between valve base 8 and recirculation hole,
Therefore after causing the pressure difference before and after through-hole to become larger, 8 compressed spring 5 of differential pressure action valve base, so that valve 9 and valve base
First through hole 91 between 8 and the circulation area of the second through-hole 81 cooperation become smaller, by flow it is constant.When inlet and outlet it
Between flow reduce, difference is caused stress by the reduction of liquid in the gap between valve base 8 and recirculation hole and is gradually become smaller, pressure difference
The power for acting on valve base 8 reduces, and spring 5 returns back to top valve base 8, and the circulation area between valve 9 and valve base 8 becomes larger,
Flow is set to become larger.Changes in flow rate generates flow resistance variation in valve base 8, by the circulation between 5 governor valve 9 of spring and valve base 8
Area is basically unchanged flow, adjusts the constant function of flow to realize.
The above, the only specific embodiment of the application, but the protection scope of the application is not limited thereto, it is any
Within the technical scope of the present application, any changes or substitutions that can be easily thought of by those familiar with the art, all answers
Cover within the scope of protection of this application.Therefore, the protection scope of the application should be with the scope of protection of the claims
It is quasi-.
