Abstract
The utility model relates to a cylindrical or spherical single-channel or dual-channel rotor reversing valve applied to pneumatic transportation and gravity flow transportation of a material pipe, in particular to a reversing valve switching and positioning mechanism. The reversing valve switching and positioning mechanism comprises a reversing valve shell with three channels, and a rotor moveably connected to the shell and provided with a material switching channel. The mechanism is characterized in that: a fixed end cover is covered on the outer side face of the rotor; two fixed limit blocks used for forcibly limiting the rotation angle range of the rotor are fixedly arranged on the inner side surface of the end cover; two position sensors are additionally arranged on the end cover; and a moveable limit block of which the position corresponds to the fixed limit blocks, and a position sensing element of which the position corresponds to the position sensors, are arranged on the outer side face of the rotor. The mechanism mainly solves the technical problem that the control precision of the rotor rotation angle is relatively poor during channel switching operation of the traditional reversing valve; and when the reversing valve switches direction, the rotation angle of a valve core can be accurately and reliably controlled.
Description
Technical field
The utility model relates to that the material pipe strength is carried, gravity flow is carried is applied to cylindrical and spherical single channel or Twin channel rotor selector valve, and particularly a kind of selector valve switches positioning means.
Background technique
Handle industrial field at the solid bulk material at present, the selector valve equipment that is absolutely necessary.The effect of selector valve is according to flow direction of material in the technological requirement controlling plumbing fixtures.Main parts size comprises housing, has the rotor of passage, end cap, manually or automatic drive.Enclosure interior has 3 passages of the isometrical material channel of conveyance conduit, connects conveyance conduit respectively.Processed and the isometrical material channel of conveyance conduit of internal rotor.End cap is used for fixing rotor.
The selector valve working principle is seen accompanying drawing 1,2, and the rotor 10 in the housing 20 rotates to an angle through the drive unit effect, can be communicated with any 1 in 2 passages, cuts off 1 passage in addition simultaneously.Domestic be no lack of manufacturer, and no matter manual or automatic, and fundamental function and reliability all can guarantee.But become more meticulous aspect the degree at product, but still have many improvements.
Selector valve is carried especially for strength in the actual use of process units, requires after switch operation is accomplished, and the inwall convex-concave does not appear in shell channel and valve core channel coaxial line, junction point.Realize this requirement, need rotor angle of swing control accurately, and present selector valve obviously also is difficult to reach this standard when switching the location.
The model utility content
The purpose of the utility model is to provide a kind of selector valve to switch positioning means; Mainly solve in the passage handover operation of existing selector valve; The technical problem that rotor angle of swing control accuracy is relatively poor when the selector valve switching direction, can realize accurately, reliably control the spool angle of swing.
For realizing above-mentioned purpose, the utility model is achieved in that
A kind of selector valve switches positioning means, and it comprises the selector valve housing with 3 passages and is movably connected in the rotor that has the material switching channel on the housing; It is characterized in that: the capping of described rotor outer side surface has fixed end cap; Described end cap inner surface is fixed 2 fixed limit pieces that are used to force the restrict rotor rotational angle range, and 2 position sensors are installed on the described end cap in addition; Have the movable limiting stopper of position on the described rotor outer side surface, and have the position sensible element of position corresponding to position sensor corresponding to the fixed limit piece.
Described selector valve switches positioning means, it is characterized in that: described fixed limit piece adopts the eccentric bolt that can finely tune limiting stopper to be fixed on the end cap side.
By said structure, the advantage of the utility model is.
1, simple and mechanical structure is adopted in the utility model design, in conjunction with the electronic sensor components and parts, has solved selector valve handover operation orientation problem.
2, the utility model is simple in structure, cheap.
When 3, the rotor positioning means of the utility model selector valve uses, accurate positioning, reliability height.
4, position-limit mechanism of the utility model and induction components and parts are installed in the selector valve enclosure interior, and protectiveness is good.The selector valve outward appearance is clean and tidy.

Embodiment
See also Fig. 3-6, it is the structural representation that a kind of selector valve of the utility model switches positioning means.It comprises the selector valve housing 2 with 3 passages and is movably connected in the rotor 1 that has the material switching channel on the housing 2.Like Fig. 3, shown in 4: described rotor 1 outer side surface capping has fixed end cap 3; Described end cap 3 inner surfaces are fixed 2 fixed limit pieces 31 that are used to force the restrict rotor rotational angle range, and 2 position sensors 32 are installed on the described end cap 3 in addition.2 fixed limit pieces are used to force the restrict rotor rotational angle range, and mainly the angle of swing designing and calculating according to the rotor needs draws 2 fixed limit pieces position and limiting stopper size separately.As a kind of optimal way, described fixed limit piece 31 adopts the eccentric bolt that can finely tune limiting stopper to be fixed on the end cap side.2 position sensors make rotor angular position realized valve position monitoring and chain control by teletransmission.Position sensor can be installed on the same end plate that limiting stopper is housed, and also can be installed on another end plate.Like Fig. 5, shown in 6: have the movable limiting stopper 11 of position on described rotor 1 outer side surface corresponding to fixed limit piece 31; And have the position sensible element 12 of position corresponding to position sensor 32; In the practical implementation, but integrally casting molds the rotor structure moulding with movable limiting stopper.
Seeing also Fig. 7,8, it has shown the rotor positioning means working condition of the utility model selector valve, and is as shown in the figure: because the effect of limiting stopper combination, the rotor rotation stroke can not exceed the scope of requirement.The effect of position sensor, rotor begins to turn to before stroke finishes from carrying out switch motion, and inductor does not receive the rotor induced signal that puts in place, and after rotateing in place, inductor just can be received induced signal.Prevented the not enough situation of rotor rotation stroke.
