Description
Technical field
The utility model relates to the hydraulic element technology in a kind of hydraulic system, particularly relates 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.
Model utility content
The technical problems to be solved in the utility model is: in order to solve the above problems, and the utility model provides a kind of one-way throttle valve to solve the problems referred to above.
The utility model solves the technological scheme that its technical problem adopts: 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 beneficial effects of the utility model are, the utility model 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, mounting type is flexible, and is not easy to block.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
The structural representation of Fig. 1 when to be the utility model one-way throttle valve flow to valve port B by valve port A,
The structural representation of Fig. 2 when to be the utility model one-way throttle valve flow to valve port A by valve port B,
Fig. 3 is the structural representation of the utility model one-way throttle valve body.
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
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As Figure 1-3, the utility model one-way throttle valve, the utility model one-way throttle valve 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 utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
