Abstract
The utility model discloses the valves of a kind of integrated all-hydraulic steering gear manual steering check valve and safety valve function, containing a valve chamber, a screw plug, a spring and a steel ball are equipped in the valve chamber, the spring closely resists the steel ball, the valve chamber is equipped with one first valve opening and one second valve opening, and the screw plug is equipped with an oilhole.The integrated all-hydraulic steering gear manual steering check valve of the utility model and the valve of safety valve function have the advantage that the structure that diverter has been simplified under the premise of function does not subtract, effectively reduce cost, good reliability.
Description
Technical field
The utility model relates to a kind of hydraulic steering gears, more precisely, being a kind of integrated all-hydraulic steering gear manpower turn
To the valve of check valve and safety valve function.
Background technique
Traditional all-hydraulic steering gear specially designs on diverter valve body to guarantee that inlet pressure is no more than setting value
Safety valve；Engine misses cause oil inlet is oil-free can be into order to prevent simultaneously, and specially devise manual steering check valve,
The oil liquid for entering diverter oil return opening from fuel tank is conveyed to oil inlet, realizes manual steering.Wherein, what safety valve was related to is related
Part processing is complex, and assembly efficiency is also very low, has seriously fettered production capacity.
Utility model content
The utility model mainly solves technical problem present in the prior art, so that providing one kind integrates all-hydraulic turn
To the valve of device manual steering check valve and safety valve function.
Above technical problems of the utility model are mainly solved by the following technical scheme:
A kind of valve of integrated all-hydraulic steering gear manual steering check valve and safety valve function, which is characterized in that described
Integrated all-hydraulic steering gear manual steering check valve and the valve of safety valve function include a valve chamber, are equipped with a spiral shell in the valve chamber
A stifled, spring and a steel ball, the spring closely resist the steel ball, and the valve chamber is equipped with one first valve opening and one
Second valve opening, the screw plug are equipped with an oilhole.
As the utility model preferred embodiment, one end of the valve chamber is in cone-shaped.
The integrated all-hydraulic steering gear manual steering check valve of the utility model and the valve of safety valve function have following excellent
Point: under the premise of function does not subtract, the structure of diverter has been simplified, has effectively reduced cost, good reliability.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structure of the integrated all-hydraulic steering gear manual steering check valve of the utility model and the valve of safety valve function
Schematic diagram；
Wherein,
1, valve chamber；2, screw plug；3, spring；4, steel ball；A, the first valve opening；B, the second valve opening；C, oilhole.
Specific embodiment
The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, to make the protection scope of the utility model apparent clear
Define.
As shown in Figure 1, the integrated all-hydraulic steering gear manual steering check valve and the valve of safety valve function include a valve chamber
1, the valve chamber 1 is interior to be equipped with a screw plug 2, a spring 3 and a steel ball 4, which closely resists the steel ball 4, which is equipped with
One first valve opening A and one second valve opening B, the screw plug 2 are equipped with an oilhole C.
One end of the valve chamber 1 is in cone-shaped.
The working principle of this valve are as follows: in electronic-controlled power steering, when the pressure off-rating of diverter oil inlet P, oil liquid
Steel ball 4 is jacked up by 2 upper oil hole C of screw plug, hence into valve chamber 1, then by the first valve opening A on valve chamber 1, last oil liquid
Fuel tank is returned to through oil return inlet T, realizes the function of safety valve on conventional steering device.In flame-out turn to, the pressure of oil inlet P is lower than
The pressure of oil outlet T, after valve chamber 1 is shifted to the right to certain distance, the second valve opening B and oil inlet P are connected, and are at this moment communicated into, oil return opening,
Realize the function of manual steering check valve on conventional steering device.
The integrated all-hydraulic steering gear manual steering check valve and the valve arrangement of safety valve function are simple, and effect is obvious, at
This is cheap, practical.
Not limited to this, any change or replacement expected without creative work should all be covered in the utility model
Protection scope within.Therefore, the protection scope of the utility model should be determined by the scope of protection defined in the claims.
