Abstract
The utility model discloses a continuous flow six-way changeover valve for fluid delivery, which consists of an upper valve and a lower valve. Each valve comprises a main tube, a left adapter and a right adapter, a valve spool is arranged at the junction of the main tube, the left adapter and the right adapter, a left valve disc and a right valve disc of the valve spool respectively extend into the left adapter and the right adapter and are connected via an elastic draw bar mechanism which is driven by cams, the cams of the upper valve and the lower valve are respectively connected with an upper rotating shaft and a lower rotating shaft, and the upper and lower rotating shafts are connected mutually. The continuous flow six-way changeover valve is reasonable in structure, adopts the cams and the rotating shafts, and is positioned via draw bars and guided by the aid of the valve discs. The valves discs are driven to move left and right by means of the rotating cam shafts, so that a left connector and a right connector are driven to be opened or closed. The changeover valve adopting the unique end-face sealing structure is capable of realizing zero leakage theoretically, and seal rings of the changeover valve can not be separated or loosened. The changeover valve is pretensioned and compressed through springs, so that processing precision can be compensated. Further, the changeover valve is flexible in reversing, low in friction resistance and large in flow area. The degree of opening of the valve can be adjusted by a directional pin.
Description
Technical field:
The utility model relates to a kind of six direction changeover valves.
Background technique:
Existing multichannel switching valve, owing to reasons such as structures, service behaviour is undesirable, can not realize that continuous flow switches.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, the conveyance fluid of favorable working performance continuous flow six direction changeover valves.
Technical solution of the present utility model is:
A kind of conveyance fluid is characterized in that: be made up of upper and lower two valves with continuous flow six direction changeover valves; Each valve wherein includes house steward, left side adapter, the right adapter, in house steward, left side adapter, the right confluce of taking over spool is set, the left flap of spool, right flap stretch into respectively in left side adapter, the right adapter, and left flap, right flap connect by the elastic draw bar mechanism of cam driven; The cam of upper and lower two valves respectively with rotate up and down axle and be connected, rotate up and down and spool interconnect.
The elastic draw bar mechanism of described cam driven comprises left and right cam pressing plate, between the left and right cam pressing plate cam is set, left and right pressing plate is connected with right connecting plate, left connecting plate by left and right pull bar respectively, right connecting plate, left connecting plate are connected with left flap, right flap respectively, the relative side with left flap of left pressing plate is provided with left stage clip, left side stage clip is fitted on the left flap, and the relative side with right flap of right pressing plate is provided with right stage clip, and right stage clip is fitted on the right flap.
In outer end, left and right flap bottom seal ring is set.
Between the left and right adapter equilibrium valve is set.
Cam is connected with the sensing pin, points to the pin both sides left and right sides locating stud that limits sensing pin left-right rotation position is set.
Point to pin and be arranged on commutation direction board top.
The utility model is rational in infrastructure, has adopted the double-cam rotatingshaft, and last rotatingshaft and following rotatingshaft are by quartet connection, and respectively with four pull bars location, the flap guiding makes the flap move left and right by the rotating cam axle, thereby makes left and right sides interface opening and closing; The spool function is the T-shape structure; Adopt unique end face seal project organization, can reach zero leakage in theory, and seal ring can not come off or loosening; Adopt the spring pretension and compress, can compensate machining accuracy; Commutation is flexible, and surface friction drag is little, and circulation area is big; Can be by pointing to the aperture of pin regulating valve.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is an embodiment's of the utility model a configuration diagram.
Fig. 2 is Fig. 1 embodiment's a commutation indication diagrammatic sketch.
A kind of conveyance fluid is made up of upper and lower two valves 1,2 with continuous flow six direction changeover valves; Each valve wherein includes house steward 3, left side adapter 4, right adapter 5, in house steward, left side adapter, the right confluce of taking over spool 6 is set, the left flap 7 of spool, right flap 8 stretch into respectively in left side adapter, the right adapter, the elastic draw bar mechanism connection that left flap, right flap drive by cam 9; The cam of upper and lower two valves respectively with rotate up and down axle and 10,11 be connected, rotate up and down and spool interconnect.
The elastic draw bar mechanism of described cam driven comprises left and right cam pressing plate 12,13, between the left and right cam pressing plate cam 9 is set, left and right pressing plate is connected with right connecting plate, left connecting plate by left and right pull bar 14,15 respectively, right connecting plate, left connecting plate are connected with left flap, right flap respectively, the relative side with left flap of left pressing plate is provided with left stage clip 16, left side stage clip is fitted on the left flap, and the relative side with right flap of right pressing plate is provided with right stage clip 17, and right stage clip is fitted on the right flap.
In outer end, left and right flap bottom seal ring 18,19 is set.Equilibrium valve 20 is set between the left and right adapter.Cam is connected with sensing pin 21, points to the pin both sides left and right sides locating stud 22,23 that limits sensing pin left-right rotation position is set.Point to pin and be arranged on commutation direction board 24 tops.
During the utility model work, by rotatingshaft 10,11 rotating cams and, because the flap of the left and right sides is connected by pull bar elasticity with spring, when rotatingshaft clockwise rotates, driving right flap by cam and pull bar moves right, and left flap also moves right, and the result takes over a left side and is unlocked, and right the adapter closed; Otherwise, when rotatingshaft rotates counterclockwise, drive left flap by cam and pull bar and be moved to the left, and right flap also being moved to the left, the result is unlocked right the adapter, and a left side is taken over and is closed.
Adapter place pressure imbalance about when avoiding switching generally should be opened equilibrium valve 20 earlier towards liquid, treats that pressure at two ends is in a basic balance to switch again.
When pointing to pin and turning to right locating stud, show that house steward and right the adapter connect; Otherwise, when the sensing pin turns to left locating stud, show house steward and left side adapter connection; When the sensing pin was in shown position (neutral position), left side adapter, right adapter and house steward connected simultaneously.On the commutation direction board, engrave scale, two discharge value of taking over about can regulate.
