Abstract
A multi-station channel change-over valve comprises a valve element, a first sealing ring, a valve body, a second sealing ring, a check ring, an end cap, a steel ball, a spring seat, a wire thread insert, a spring, a ball expanding end cap, an indicating disk, nuts and a manipulating rod, wherein the valve element is installed in the valve body in an inserted mode, the check ring is installed at one end of the valve element, the first sealing ring and the second sealing ring are installed on the valve body and the valve element respectively, the steel ball is installed on a locating hole formed in the valve element through the spring seat, the spring and the wire thread insert in a pressed mode, the manipulating rod is connected with the valve element through threads, the manipulating rod and the valve element are locked by the nuts, and the indicating disk is installed on the valve body. The multi-station channel change-over valve has the advantages of being compact in structure and easy to operate, save labor and is accurate in switching of an oil way channel and locating, clear in indicating, easy to machine, low in cost, convenient to install and the like.
Description
Technical field
The utility model belongs to valve technology field, is specially a kind of multi-position channel switching valve.
Background technique
In prior art, need a plurality of valves during complicated pipelines oil duct switch operating state.When needs change a working state or station, need the one or more valves of operation, particularly when working state or station frequent transitions, complicated operation not only, and make mistakes easily, cause working state of system or station to get muddled, damage system and equipment, also security incident can take place when serious, cause bigger economic loss.
The model utility content
The technical problem that the utility model solves is to provide a kind of multi-position channel switching valve of compact structure, open when being used for system's many places oil circuit and the communication of each passage oil circuit and ending, and oil circuit switching location is set and indicates worker's energy, reach the same valve of operation and just realize the accurate conversion of a plurality of working staties or station, solved the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
The multi-position channel switching valve, comprise: spool, seal ring one, valve body, seal ring two, back-up ring, plug, steel ball, spring seat, swivel nut, spring, ball rise plug, indicator panel, nut, operating handle, spool is inserted in the valve body, back-up ring is installed in spool one end, seal ring one and seal ring two are installed in respectively on valve body and the spool, steel ball is fitted on the positioning hole that spool opens by spring seat, spring, swivel nut, operating handle is threaded with spool, use nut check, indicator panel is installed on the valve body.
Compared with prior art, the beneficial effects of the utility model are: the utility model multi-position channel switching valve makes spool rotate relative to valve body by handling operating handle, steel ball and spring seat are squeezed, under the effect of spring force, move around, fall into locating slot in the spool rotary course, asphalt channel also switches thereupon, and the steel ball location obviously, precisely, the oil circuit of the corresponding indicator panel of offering on the spool of station indication groove institute be can observe simultaneously and clear and definite equipment station of living in and working state numbered; Advantages such as the utility model also has compact structure, it is simply laborsaving to handle, asphalt channel switches accurately, accurate positioning, indication are clear and definite, be easy to processing, with low cost, easy for installation.
