Abstract
The utility model relates to a fixed type one-way throttle valve and belongs to the technical field of hydraulic directional control valves. The fixed type one-way throttle valve comprises a valve seat provided with an oil inlet port and an oil outlet port and a valve core arranged in the inner cavity of the valve seat. The inner cavity of the valve seat is in a column shape extending along the flowing direction of oil fluids, and the oil outlet port end is provided with a valve core limit piece. The valve core is of column shape with a section smaller than the section of the inner cavity, and the end adjacent to the oil inlet port is provided with a choke plug used for sealing up the oil inlet port. The fixed type one-way throttle valve can realize a one-way throttling through a simple structure, moreover, the valve core fails to revolve inside the valve seat, thereby the noise is avoided.
Description
Technical field
The utility model relates to a kind of throttle valve, and especially a kind of fixed one-way throttle valve belongs to hydraulic directio control valve technical field.
Background technique
The restriction size of existing fixation type throttle valve can not be adjusted, and the size of its restriction generally is predetermined by designing and calculating, in some hydraulic control occasion, needs unidirectional throttling.Understand according to the claimant, the valve core structure of existing fixed one-way throttle valve is reasonable inadequately, can occur " spinning " phenomenon during work, therefore has the bigger shortcoming of noise, and is all the more so when especially working under the mesohigh hydraulic environment.
The model utility content
The purpose of this utility model is: the shortcoming at prior art exists provides a kind of fixed one-way throttle valve with the valve core structure that abates the noise, thereby more is applicable to mesohigh hydraulic oil environment.
The technological scheme that the utility model adopted is: fixed one-way throttle valve constitutes by having into and out of the valve seat of hydraulic fluid port and the spool that is placed in the valve base cavity; The inner chamber of described valve seat is the column of extending along the fluid flow direction, and the oil outlet end is equipped with the spool bounding means; Described spool is the column of cross section less than intracavity section, an end of contiguous filler opening have can the described filler opening of shutoff plug.
Like this, the utility model not only can be realized folk prescription to throttling by simple structure, and spool can not spin in valve seat, thereby has avoided the generation of noise.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is an embodiment's of the utility model a structural representation.
Embodiment
Embodiment one
The fixed one-way throttle valve of present embodiment as shown in Figure 1, major part: valve seat 1, steel ball 2, position limit pin 3, steel ball seat 4.The two ends up and down of valve seat 1 are respectively into and out of hydraulic fluid port, inner chamber be along the fluid flow direction extend cylindric, the oil outlet end is equipped with spool position limit pin 3,, be used to limit the maximum opening width between spool and valve seat 1 filler opening.Spool in valve seat 1 inner chamber is made up of steel ball 2 and steel ball seat 4.What steel ball seat 4 was the cross section less than intracavity section is cylindric, and steel ball 2 is riveted on an end of steel ball seat 4 contiguous filler openings, the plug that formation can the shutoff filler opening.Valve seat 1 is shaped on outside thread, is used for being connected with auxiliary products.
During work, spool can float with oil liquid pressure in valve seat, to the next throttle valve of opening, upwards then closes throttle valve.The said structure of present embodiment not only can satisfy the usage requirement of fixed one-way throttle valve, and spool can not spin in valve seat, thereby has avoided the generation of noise.In addition, present embodiment is simple in structure, good manufacturability, be convenient to install, and therefore is easy to apply.
In addition to the implementation, the utility model can also have other mode of executions.For example, an end of the contiguous filler opening of spool also can be to be circular cone or dull and stereotyped plug; For another example, the valve seat oil outlet end is installed limiting board, has oil outlet on the limiting board.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
Claims (4)
1. a fixed one-way throttle valve constitutes by having into and out of the valve seat of hydraulic fluid port and the spool that is placed in the valve base cavity; It is characterized in that: the column of the inner chamber of described valve seat for extending along the fluid flow direction, the oil outlet end is equipped with the spool bounding means; Described spool is the column of cross section less than intracavity section, an end of contiguous filler opening have can the described filler opening of shutoff plug.
2. a kind of fixed one-way throttle valve according to claim 1, it is characterized in that: described spool is made up of steel ball and steel ball seat, described steel ball seat is the column of cross section less than intracavity section, and described steel ball is riveted on an end of the contiguous filler opening of steel ball seat, the plug that formation can the shutoff filler opening.
3. a kind of fixed one-way throttle valve according to claim 1 is characterized in that: an end of the contiguous filler opening of described spool is circular cone or dull and stereotyped plug.
4. a kind of fixed one-way throttle valve according to claim 1 is characterized in that: described valve seat oil outlet end is installed limiting board, has oil outlet on the described limiting board.
