Abstract
A changeover valve directly installed on a track for concentrative installation has the same valve body with a changeover valve installed on a manifold base, and the two changeover valves are adaptive to both of the two installations. The openings of a hole P for supplying pressure fluid, first output holes A1, B1, exhaust holes EA, EB are arranged under a valve body 6 of a changeover valve 1. Simultaneously, the openings of two second output holes A2 and B2 which are communicated with the two first output holes are arranged on the valve body 6. A supply path 8 and two discharge paths 9a, 9b are arranged in the valve body 6, wherein the supply path 8 and the two discharge paths 9a, 9b are communicated with each hole above. The underside of the valve body is taken as a mounting surface on which the track for concentrative installation, a manifold base 2 and a seal plate can be selectively installed.
Description
The present invention relates to a kind of changing valve, more particularly is to be connected with a plurality of and changing valve that use about concentrating.
For instance, a plurality of changing valves are installed on the track of long size and manage the technology of these changing valves concentratedly, well-known, need not for example special.At this moment, these changing valves directly are arranged on the above-mentioned track or by the manifold base setting.
With the manifold base is media, be connected with on the track time above-mentioned changing valve is a plurality of, as valve body, adopt the supply hole of pressure fluid and delivery outlet and tap hole all are opened in structure below this valve body, by this changing valve is installed on the manifold base, make above-mentioned each hole be communicated in this each opening above manifold base respectively, by the delivery outlet delivery pressure fluid of this manifold base.Also have, pressure fluid when changing valve is directly exported, is not opened delivery outlet below valve body, and opened in the above, the delivery outlet output above this.
On the other hand, when changing valve is installed with the state on track of directly being connected with, as valve body, be provided with from this valve body and run through pressure fluid supply passage and the drain passageway that changing valve is connected with direction, employing is being communicated with these paths respectively with supply hole and tap hole, and delivery outlet is opened structure on valve body.
But, even the same changing valves such as driving means of its size and valve body, also because of directly installing to track, still by manifold base difference is installed, valve body is configured with different, for this reason, corresponding to installation method, must prepare multiple valve body, existence can not be taked the problem of general changing valve.
Also have,, then have by a plurality of manifold base faciations being interconnected and tie the method that is connected with a plurality of changing valves,, and directly be installed between the changing valve of track and do not have interchangeability even in this occasion with suitable means if above-mentioned manifold base is not installed not in orbit.
The problem that the present invention will solve is can enough isomorphic valve bodies, directly is installed on to install concentratedly with on the track and the changing valve that uses and be installed on the installation of changing valve two aspects of using on the manifold base.
In order to solve above-mentioned problem, the present invention has pressure fluid supply hole, delivery outlet, tap hole and have the valve body of valve opening and the spool that slides in above-mentioned valve opening; Slip by this spool, under above-mentioned delivery outlet, supply hole and tap hole connected state, change and concentrated a plurality of changing valves that are connected with use, it is characterized in that above-mentioned valve body is provided with at changing valve and is connected with pressure fluid supply passage and the drain passageway that direction connects.And above-mentioned output is separated into the 1st delivery outlet and the 2nd delivery outlet that is interconnected; Above-mentioned supply hole, the 1st delivery outlet and tap hole in the valve body lower aperture, the 2nd delivery outlet opening on valve body, and above-mentioned supply hole and tap hole are communicated with above-mentioned supply hole path and drain passageway respectively; Above-mentioned supply passage, drain passageway and the 2nd delivery outlet form switching by the mounting or dismounting of stick harness; Become below the above-mentioned valve body installing concentratedly with track and having the manifold base of the supply stream that is communicated in above-mentioned supply hole, the 1st delivery outlet, tap hole respectively, delivery outlet, discharge stream and between this valve body and be installed on the above-mentioned supply hole of Close All between the above-mentioned track of this valve body and the seal disc of the 1st delivery outlet and tap hole can be selected the attachment face installed.
Changing valve is installed in manifold base and concentrates and to be connected with when a plurality of, and the valve body of changing valve is arranged on the manifold base; Supply hole, the 1st delivery outlet and tap hole in the valve body lower aperture are communicated in corresponding opening above the manifold base respectively.Like this, close supply passage, drain passageway and the 2nd delivery outlet that is arranged on the valve body, can manifold base be supplied with, export and discharge by pressure fluid by stick harness is installed.
Also have, the 1st delivery outlet is closed, can make the 2nd delivery outlet output of pressure fluid from opening on valve body with suitable means.
A plurality of changing valves are directly installed on the track and concentrate when being connected with, below valve body, install in the seal disc, above-mentioned track is installed as topped sealing dish.At this moment, because with above-mentioned seal disc Close All supply hole, the 1st delivery outlet and tap hole, so pressure fluid is being supplied with, in the discharge, exported from the 2nd delivery outlet to supply hole and tap hole from the supply passage that is arranged at valve body and drain passageway.
Thereby, also can be used for occasion that is directly installed on the track and the occasion that is installed on the manifold base having isomorphic valve body.
