Abstract
The invention relates to a one-way throttle valve. The one-way throttle valve comprises a one-way passage and a throttle passage, wherein the one-way passage flows from a valve port A to a valve port B, and the one-way passage runs by a throttle groove I, a radial hole and an axial hole; the throttle passage flows from the valve port B to the valve port A, and the throttle passage runs by the axial hole, the radial hole, the throttle groove I and a throttle groove II; the throttle groove I, the throttle groove II, the radial hole and the axial hole are arranged on a valve body, both the valve port A and the valve port B are arranged on a valve seat, the valve seat is provided with a cavity I, and the valve body can slide between the valve port A and the valve port B in the cavity I. By adopting the one-way throttle valve, the one-way valve function and the throttle valve function can be simultaneously realized; the function of the throttle valve is realized by adopting the throttle groove form. The one-way throttle valve is not only small and compact in structure and flexible in installation way, but also unlikely to block.
Description
Technical field
The present invention relates to the hydraulic element technology in a kind of hydraulic system, particularly relate to a kind of one-way throttle valve.
Background technique
The effect of common one-way valve is that hydraulic oil can only be flowed along a direction, mustn't it oppositely flow backwards, the effect of conventional throttle valve is by changing throttling cross section or chock length to control the flow control valve of fluid flow, throttle valve then be may be combined with into one-way throttle valve with one-way valve parallel connection, namely one-way valve can be opened in specific direction, without throttling action, cannot open one-way valve in the opposite direction with certain party, can only flow out from throttle valve, have throttling action.
Now general one-way throttle valve is all basic to be made up of two elements, a valve pocket having one-way valve effect concurrently adds a spool with throttle orifice and combines, this one-way throttle valve not only boundary dimension is larger, in the occasion of ask for something compact structure, difficulty is installed, and throttle orifice is easy to by the mechanical admixture in fluid or because being oxidized the size that the dirt such as colloid, carbon slag of separating out blocks or affects throttle orifice because these dirts are adsorbed on throttle orifice surface, and then impact is by the uninterrupted of throttle orifice.
Summary of the invention
The technical problem to be solved in the present invention is: in order to solve the above problems, and the invention provides a kind of one-way throttle valve and solves the problems referred to above.
The technical solution adopted for the present invention to solve the technical problems is: a kind of one-way throttle valve, has half-duplex channel and throttling passage,
Described half-duplex channel flows to valve port B by valve port A, and described half-duplex channel is by way of throttling groove one, radial hole, axial bore;
Described throttling passage flows to valve port A by valve port B, and described throttling passage is by way of axial bore, radial hole, throttling groove one, throttling groove two;
Described throttling groove one, throttling groove two, radial hole, axial bore are all arranged on valve body, described valve port A and valve port B is all arranged on valve seat, have cavity one in described valve seat, described valve body to be arranged in cavity one and can to slide between valve port A and valve port B.
Described axial bore is arranged on valve body one end near valve port B, and described throttling groove one, throttling groove two are arranged on valve body one end near valve port A.
Described throttling groove one has two, and circumference is distributed on valve body.
Described throttling groove two is arranged on the end of valve body.
The invention has the beneficial effects as follows, the present invention realizes one-way valve and throttle valve two kinds of functions by improved valve body simultaneously, and adopts the form of throttling groove to realize the function of throttle valve, and not only compact structure is compact, and mounting type is flexible, and is not easy to block.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
The structural representation of Fig. 1 when to be one-way throttle valve of the present invention flow to valve port B by valve port A,
The structural representation of Fig. 2 when to be one-way throttle valve of the present invention flow to valve port A by valve port B,
Fig. 3 is the structural representation of one-way throttle valve body of the present invention.
In figure 1, throttling groove one, 2, radial hole, 3, axial bore, 4, throttling groove two, 5, valve body, 6, valve seat, 7, cavity one.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As Figure 1-3, one-way throttle valve of the present invention, one-way throttle valve of the present invention comprises valve seat 6 and valve body 5, valve seat 6 has valve port A and valve port B, have cavity 1 in valve seat 6, valve body 5 slides and intercepts and set up the contact of valve port A and valve port B in cavity 1, in use, when flowing to valve port B by valve port A, one-way valve opens, when flowing to valve port A by valve port B, closed check valve, fluid, by throttle valve, now has throttling action.
As shown in Figure 3, throttling groove 1, throttling groove 24, radial hole 2, axial bore 3 are all arranged on valve body 5, axial bore 3 is arranged on valve body 5 one end near valve port B, throttling groove 1, throttling groove 24 are arranged on valve body 5 one end near valve port A, throttling groove 1 has two, circumference is distributed on valve body 5, and throttling groove 24 is arranged on the end of valve body 5.
Specific works principle, as Fig. 1, when hydraulic oil flows to valve port B by valve port A, valve body 5 moves right, one-way valve opens, hydraulic oil from valve port A by way of throttling groove 1, radial hole 2, axial bore 3 to valve port B;
As Fig. 2, when hydraulic oil flows to valve port A by valve port B, valve body 5 is moved to the left, closed check valve, hydraulic oil by valve port B through axial bore 3, radial hole 2, throttling groove 1, throttling groove 24 to valve port A, have throttling action.
Valve body as shown in the figure, when hydraulic oil is flowed by valve port A to valve port B, one-way valve opens, if when the throttling groove 24 of valve body 5 having impurity or foreign matter, be easy to be gone out by fluid, not easily choking phenomenon occur.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to right.
