Description
Technical field
The present invention relates to hydraulic valve technology, especially a kind of regulating valve with rotary runner.
Background technique
Hydraulic valve is many kinds of, is widely used, as regulating valve is mainly used in robot control system(RCS) by sets requirement control technique
Parameter.In existing regulating valve structure, pressure medium faces trim direction from valve body direct admission valve in-core with forward direction mostly, though
Some technical measures are so used in terms of medium runner, impact are generated to valve inner part when preventing medium from entering, but these are situated between
The structure type in mass flow road still unavoidably generates certain shock effect when medium enters to elements such as valve rod, spools, draws
Valve body vibration is played, causes to connect fracture between valve components, so as to shorten the service life of regulating valve.
Summary of the invention
The technical problem to be solved by the present invention is in order to overcome the deficiencies in the existing technology, the present invention, which provides, a kind of can have
Effect avoids generating the regulating valve with rotary runner directly impacted to element in valve.
The technical solution adopted by the present invention to solve the technical problems is: a kind of regulating valve with rotary runner, tool
There is valve body, be located at the intracorporal spool of valve and be fixed on the valve deck of valve body end face, the spool is connected with the valve stretched out outside valve deck
Bar is equipped with valve seat in valve body, and valve body side offers the inlet of pressure medium entrance, and the valve body other side offers and spool
Inner hole communicates the liquid outlet of outflow pressure medium, and turnbarrel is equipped on the valve seat, and the turnbarrel has set
Cylinder, sleeve body inner wall are slidably matched with spool, have in sleeve body sidewall around the circumferential rotation direction sleeve body in the shape of a spiral of sleeve body
Inlet is connected in the medium runner of inner cavity, the medium runner outer end, and medium runner inner end is connected the inner cavity of sleeve body and pushed
Spool is mobile.
Preferably, three column, each column five medium runners, the medium runner inner end are equipped in the sleeve body sidewall
It is tangent with sleeve body internal chamber wall and connect sleeve intracoelomic cavity.Fluid media (medium) enters medium runner outside sleeve body in this way, along set
Substantially 120 ° of cylinder circumferential flow, it is tangent to enter in sleeve body.
To keep velocity of medium uniform, the interior external port diameter of the medium runner is identical.
The beneficial effects of the present invention are: the present invention is passed through medium using the medium runner of helical form rotation direction, so that medium edge
Sleeve body rotation after tangentially enter sleeve intracoelomic cavity in, effectively prevent medium to trim directly washing away, extend
The service life of regulating valve internal element.
Detailed description of the invention
The present invention is further described with embodiment with reference to the accompanying drawing.
Fig. 1 is structural schematic diagram of the invention.
Fig. 2 is the structural schematic diagram of turnbarrel of the present invention
Fig. 3 is A-A schematic cross-sectional view in Fig. 2.
In figure: 1. valve body, 2. spool, 3. valve deck, 4. valve rod, 5. valve seat, 6. inlet, 7. liquid outlet, 8. turnbarrel

Specific embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These attached drawings are simplified schematic diagram, only with
Illustration illustrates basic structure of the invention, therefore it only shows the composition relevant to the invention.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of regulating valve with rotary runner has valve body 1, and valve body end face is fixed with
Valve deck 3 is equipped with valve seat 5 and spool 2 in valve body 1, and valve body left-hand end has inlet 6, and valve body right end has liquid outlet 7, valve
Seat 5 is mounted in valve body 1 on two bearing ribs in left and right, and wherein the bearing rib on the left side blocks between inlet 6 and liquid outlet 7
Connection.
Turnbarrel 8 is installed, spool 2 is mounted in sleeve body 8-1 inner wall, and the spool 2 connects on the valve seat 5
There is the valve rod 4 stretched out outside valve deck 3.
The turnbarrel 8 has sleeve body 8-1, and sleeve body 8-1 inner wall is slidably matched with spool 2, the side sleeve body 8-1
Medium runner 8-2 in wall with three circumferentially uniformly distributed column, the arrangement of five axially spaced-aparts of each column, the medium runner 8-2's is interior
Outer end bore is identical, and inlet 6 is connected in the outer end medium runner 8-2, and medium runner 8-2 circumferentially revolves in the shape of a spiral around sleeve body 8-1
To the inner cavity sleeve body 8-1, the inner end medium runner 8-2 is tangent with sleeve body 8-11 internal chamber wall and connects the inner cavity sleeve body 8-1, is passed through
Pressure medium and push spool 2 mobile.
The medium runner 8-2 is made of 3D printing technique, and pressure medium enters in valve body 1 from inlet 6, is then existed
It is last tangentially to enter the inner cavity sleeve body 8-1 around 120 ° of sleeve body 8-1 annularly flow in medium runner 8-2, push spool 2 mobile,
Final pressure medium flows out valve body 1 from liquid outlet 7 through 2 inner hole of spool.
The present invention is passed through pressure medium using the medium runner 8-2 of helical form rotation direction, so that pressure medium is along sleeve body
8-1 rotation after tangentially enter sleeve body 8-1 in it is intracavitary, such medium is not flushed in directly in valve on element, is effectively prevented
Pressure medium causes to connect between element in valve to be broken to directly the washing away the caused vibration of valve body 1 of element in valve, extends
The service life of element in valve.
Above-mentioned regulating valve is especially suitable for liquid, gas containing a small amount of particle and with the operating condition of higher operting differential pressure (3Mpa)
Lower use, executing agency's thrust is smaller, and dynamic stability is good, can solve valve surge problems, prevents under surging condition, valve
Door the open position provided ceaselessly up and down surge and cause the fluctuation of flow, puzzlement is brought to technique production.
Taking the above-mentioned ideal embodiment according to the present invention as inspiration, through the above description, relevant staff is complete
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property range is not limited to the contents of the specification, it is necessary to which the technical scope thereof is determined according to the scope of the claim.
