Abstract
The utility model relates to a changeover valve capable of being switched synchronously. The changeover valve capable of being switched synchronously comprises a base, a valve body, a valve cover, a valve core and turning wheels. The valve body is fixedly and coaxially mounted on the base, the valve cover is mounted at the upper end of the valve body coaxially, the valve core is mounted in the valve body in guiding and rotating modes, the valve rod is vertically and coaxially mounted on the valve core, the valve core and the valve body are divided into an upper position and a lower position and are provided with reversed symmetrical semi-open type channels, the semi-open type channels formed in the upper layer and the lower layer are perpendicular, a thrust bearing is coaxially mounted at the lower end of the valve rod, and the thrust bearing is coaxially embedded in a mounting hole formed in the lower portion of the valve body. The changeover valve capable of being switched synchronously can replace multiple reversing valves, mounting amount of valves is reduce remarkably, construction time is shortened, construction materials are reduced, and piping layout is simple, occupied area and space are saved, operation is flexible and fast, time and labor are saved, and misoperation phenomena are reduced remarkably.
Description
Technical field
The utility model belongs to change-over valve field, especially a kind of synchronous changeover valve that switches.
Background technique
Heat pump need to carry out the switching of working medium commutation, thereby change the refrigeration of unit or heat mode of operation, at present, conventionally adopt four-way change-over valve or waterway switching device realization are installed in the outlet port of unit inner compressor, and four-way change-over valve or waterway switching device respectively have pluses and minuses.Wherein, four-way change-over valve compact structure, easy for installation, but because four-way change-over valve is expensive, general only for Pump for Medium and Small Power Generating Set, be not suitable for using in a large number in large-scale unit; And that waterway switching device has cost is low, the advantage such as fault is few, but line arrangement is comparatively complicated, take up room larger, and how valve quantity easily causes misoperation.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provide a kind of simple in structure, reasonable in design, be convenient to safeguard, point to clear and definite synchronous switching changeover valve.
The utility model solves its technical problem and takes following technological scheme to realize:
A kind of synchronous changeover valve that switches, comprise base, valve body, valve gap, spool and runner, on base, be coaxially fixedly mounted with valve body, valve gap is coaxially installed in valve body upper end, in valve body, guided rotation is provided with a spool, spool is the coaxial valve rod of installing vertically, this valve rod upper end is stretched out valve body and is coaxially installed with a runner, thereby this runner drives spool to rotate control valve path, the left side of four sides, described valve body upper strata outer wall is all shaped with the channel opening that a structure is identical, the right side of valve body lower floor four sides outer wall is all shaped with the channel opening that a structure is identical, it is characterized in that: described spool and valve body are divided into, lower double-deck position is all shaped with the semi open model passage of inversion symmetry, on this, the made semi open model passage of lower bilayer is mutually vertical, described valve rod lower end is coaxially installed with a thrust bearing, and this thrust bearing is coaxially inlaid in the made mounting hole of valve body lower portion.
And described spool middle part is provided with a stuffing box gland with the coaxial slipper seal of valve body surface of contact.
And radial equipartition is shaped with eight graduated scale pieces corresponding with exit position on described valve gap, runner outer radial equipartition is fixed with the handle of four circumscribed directions.
Advantage of the present utility model and good effect are:
The utility model adopts a valve can substitute multiple change-over valves, and the installation quantity of valve significantly reduces, and shortens the engineering time, reduce construction material, line arrangement is simple, saves occupation area and space, flexible operation is quick, time saving and energy saving, and significantly reduces misoperation phenomenon.
