Furthermore, a plurality of second through holes are formed in the outer side of the valve shell at intervals in the circumferential direction.
Further, the rotary joint comprises a first connecting piece and a second connecting piece; one end of the first connecting piece is coaxially inserted into the third through hole, and the other end of the first connecting piece extends outwards; the second connecting piece is fixedly connected with the first connecting piece, and the fifth through hole is formed in the outer side of the second connecting piece.
Furthermore, a second access port is further installed in the fifth through hole.
Furthermore, the number of the rotary joints is two, and two rotary joints are respectively installed at two ends of the valve core.
Adopt above-mentioned scheme, the beneficial effects of the utility model are that:
the rotary motion can be done relatively with the case to the valve casing of this rotary valve, and in a plurality of first business turn over interfaces of valve casing outside installation, and then the inflow or the outflow of the medium of adaptable different grade type, and general nature is strong, simultaneously, whole reasonable in design, compact structure, small, the installation of being convenient for are dismantled, with low costs, easily quantization production, practicality are strong.
