Description of the drawings
Fig. 1 is the two-way structure of reversing valve figure of a kind of adjustable type that the disclosure proposes.
Specific implementation mode
Referring to Fig.1, the two-way reversal valve of a kind of adjustable type that the disclosure proposes, including：Shell 1, first partition 2, second every
Plate 3, the first cock body 4, the first spring 5, mounting plate 6, screw rod 7, orientation lever 8, the second cock body 9 and second spring 10.
First partition 2 and second partition 3 are installed in the inside of shell 1 and are mutually isolated the by 1 inside division of shell
One chamber 1-1, second chamber 1-2 and third chamber 1-3.First partition 2 is equipped with connection first chamber 1-1 and second chamber 1-
2 first through hole, second partition 3 are equipped with the second through-hole of connection second chamber 1-2 and third chamber 1-3.Shell 1 is equipped with
Input port 1-4, the first delivery outlet 1-5 and second for being respectively communicated with first chamber 1-1, second chamber 1-2 and third chamber 1-3 are defeated
Export 1-6.Specifically, first partition 2 and second partition 3 are arranged parallel.
The movement of first cock body 4 is mounted in first chamber 1-1, and motion track passes through first through hole, and the first cock body 4 supports
In the state of first partition 2, first through hole blocks.Screw rod 7 is inserted into first chamber 1-1 from 1 outside of shell and is rotatablely installed, spiral shell
Bar 7 is static relative to shell 1 in the axial direction.Specifically, in present embodiment, shell 1 is equipped with limit chamber, in limit chamber
It is rotatablely equipped with flange ring 13, flange ring 13 is set on screw rod 7 and is fixedly connected with screw rod 7, right will pass through flange ring 13
Screw rod 7 carries out the stop on axis direction.
In present embodiment, the liquid of input port 1-4 inputs is put aside in first chamber 1-1, then according to first through hole and
The unobstructed situation of second through-hole is exported from the first delivery outlet or the second delivery outlet.
Mounting plate 6 is located in first chamber 1-1 and is set on screw rod 7, and mounting plate 6 is threadedly coupled with screw rod 7.Orientation lever
8 are mounted in first chamber 1-1 and are parallel to the setting of screw rod 7, and 8 one end of orientation lever, which passes through mounting plate 6 and slided with mounting plate 6, to be connected
It connects.Screw rod 7 cannot be followed to rotate when screw rod 7 rotates in this way, limiting mounting plate 6 by orientation lever 8, to which screw rod 7 rotates
When, mounting plate 6 can only slidably reciprocate according to 7 rotation direction of screw rod along 7 axis direction of screw rod.Distinguish at the both ends of first spring 5
Connection plate 6 and the first cock body 4, the first cock body 4 are moved with the flexible of the first spring 5.In this way, stifled in the first cock body 4
In the state of filling in first through hole, by the relative distance between 7 adjustable installation board 6 of rotary screw and the first cock body 4, to adjust
The reduction length for saving the first spring 5 adjusts the pressure that the first spring 5 is applied to the first cock body 4.The movement installation of second cock body 9
In second chamber 1-2, motion track passes through the second through-hole.Second spring 10 is mounted in third chamber 1-3 and positioned at the
Two sides of the cock body 9 far from second partition 3, the second cock body 9 are connect with 10 movable end of second spring, and with second spring 10
It stretches and moves.Against in the state of second partition 3, the second through-hole blocks second cock body 9.In this way, in present embodiment, when
When the pressure that one spring 5 is applied to the first cock body 4 is applied to the pressure of the second cock body 9 less than second spring 10, input port 1-4 is defeated
The liquid entered enters second chamber 1-2, as the pressure in second chamber 1-2 increases, washes the first cock body 4, input port open first
1-4 inputs liquid and passes through the first delivery outlet 1-5 outputs through second chamber 1-2 and first chamber 1-1；When the first spring 5 is applied to
When the pressure of first cock body 4 is applied to the pressure of the second cock body 9 more than second spring 10, the liquid of input port 1-4 inputs enters
Second chamber 1-2 washes the second cock body 9 open first as the pressure in second chamber 1-2 increases, and input port 1-4 inputs liquid warp
Second chamber 1-2 and third chamber 1-3 passes through the second delivery outlet 1-6 outputs.Second spring 10 is applied to the pressure of the second cock body 9
Constant, the pressure that the first spring 5 is applied to the first cock body 4 can be adjusted by the plate 6 that is slidably installed, so, it is changeable by screw rod 7
The outbound course of the reversal valve.Meanwhile the pressure that the first cock body 4 is applied in the first spring 5 applies more than second spring 10
To under the pressure condition of the second cock body 9, using the second delivery outlet as the delivery outlet under normality, the first delivery outlet as pressure relief opening,
Also mounting plate 6 can be adjusted by screw rod 7, to which pressure release opportunity be arranged, ensure the stabilization of the second delivery outlet output flow velocity.
Specifically, in present embodiment, third spring 11 is arranged on orientation lever 8, the both ends of third spring 11 connect respectively
Body contact body 1 and mounting plate 6；The 4th spring 12 is additionally provided in first chamber 1-1, the both ends of the 4th spring 12 are separately connected shell 1
With mounting plate 6, and the 4th spring 12 and third spring 11 are symmetrical arranged about screw rod 7.Third spring 11 and the 4th spring 12
The stabilization advantageously ensured that in 6 motion process of mounting plate is set, to ensure the steady of the first cock body 4.
In present embodiment, the telescopic direction of the first spring 5 is parallel to screw rod 7, to be further ensured that the fortune of the first cock body 4
Dynamic stability, after ensureing that first through hole is unimpeded, the first cock body 4 can also former route reset blocking first through hole.
In present embodiment, the first cock body 4 is that either the second cock body of convex platform structure 9 is taper platform or convex to taper platform
Shape platform structure.
The preferable specific implementation mode of the above, the only disclosure, but the protection domain of the disclosure is not limited thereto,
Any one skilled in the art in the technical scope that the disclosure discloses, according to the technical solution of the disclosure and its
Open design is subject to equivalent substitution or change, should all cover within the protection domain of the disclosure.
