Description
Technical field
The utility model relates to selector valve, also relates to the Reinforcing Steel Crooking Machine installing this selector valve.
Background technique
Selector valve comprises housing, and housing has inlet passage and the flow pass of hydraulic fluid; In prior art, the controlling component that its housing does not have pressure excessive, such selector valve has awkward shortcoming, easily occurs damaging because pressure is excessive when it uses, and also has the shortcoming easily heating up, affect because making pressure large using effect and working life.
Reinforcing Steel Crooking Machine is provided with selector valve, and in prior art, its selector valve installed does not have can the parts of pilot pressure, have the shortcoming affecting using effect and working life.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned shortcoming, provides one can pilot pressure, ensures working life, reduces hydrovalve---the pressure-adjustable selector valve that temperature raises; Also provide simultaneously a kind of can pilot pressure, ensure working life, reduce temperature raise Reinforcing Steel Crooking Machine.
The technological scheme of the utility model selector valve is achieved in that pressure-adjustable selector valve, comprise commutation valve housing, described housing has inlet passage and the flow pass of hydraulic fluid, it is characterized in that: described selector valve housing is also provided with current by pass, described current by pass is communicated with in the middle of inlet passage and flow pass, described earial drainage is logical is the passage of " fourth " font, comprise cross aisle and longitudinal channel, liquid-return box is communicated with below longitudinal channel, cross aisle inboard has the protruding circle of holding, cross aisle installs steel ball from inside to outside successively, spring and adjusting bolt, under the action of the spring, steel ball and the protruding circle of holding can form sealing state.
Say further, the length that described adjusting bolt stretches in cross aisle is adjustable.
The technological scheme of the utility model Reinforcing Steel Crooking Machine is achieved in that Reinforcing Steel Crooking Machine, comprises Bending machines body, and described Bending machines body is provided with selector valve, it is characterized in that: described selector valve is the selector valve of above-mentioned feature.
The beneficial effects of the utility model are:
Such selector valve has can pilot pressure, and ensure working life, reduce the advantage that temperature raises, the length that described adjusting bolt stretches in cross aisle is adjustable, also has the advantage that setting pressure is adjustable;
Such Reinforcing Steel Crooking Machine have can pilot pressure, ensure working life, reduce temperature raise advantage; The length that described adjusting bolt stretches in cross aisle is adjustable, also has the advantage that setting pressure is adjustable.
Accompanying drawing explanation
The cross-sectional view of this practical selector valve of Fig. 1.
Wherein: 1, housing 2, inlet passage 3, flow pass 4, cross aisle 5, longitudinal channel 6, protruding circle 7, steel ball 8, spring 9, adjusting bolt.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, pressure-adjustable selector valve, comprise commutation valve housing 1, described housing has inlet passage 2 and the flow pass 3 of hydraulic fluid, it is characterized in that: described selector valve housing is also provided with current by pass, described current by pass is communicated with in the middle of inlet passage and flow pass, described earial drainage is logical is the passage of " fourth " font, comprise cross aisle 4 and longitudinal channel 5, liquid-return box is communicated with below longitudinal channel, cross aisle inboard has the protruding circle 6 of holding, cross aisle installs steel ball 7 from inside to outside successively, spring 8 and adjusting bolt 9, under the action of the spring, steel ball and the protruding circle of holding can form sealing state.
Like this, when the pressure of hydraulic fluid is greater than the pressure of spring, cross aisle 4 is just got through, and hydraulic fluid flow into liquid-return box from longitudinal channel, eases off the pressure, and has advantage of the present utility model.
Say further, the length that described adjusting bolt 9 stretches in cross aisle is adjustable.Like this, the pressure of spring can be adjusted.
The technological scheme of the utility model Reinforcing Steel Crooking Machine is achieved in that Reinforcing Steel Crooking Machine, comprises Bending machines body, and described Bending machines body is provided with selector valve, it is characterized in that: described selector valve is the selector valve of above-mentioned feature.
The foregoing is only specific embodiment of the utility model, but structure characteristic of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the change done or modification are all encompassed in the scope of the claims of the present utility model.
