Abstract
The utility model discloses a continuous-flow three-way shifting valve for conveying fluids. The continuous-flow three-way shifting valve comprises a main pipe, a left connecting pipe and a right connecting pipe, wherein valve cores are arranged at the joints of the main pipe, the left connecting pipe and the right connecting pipe; a left valve flap and a right valve flap of the valve core extend in the left connecting pipe and the right connecting pipe respectively; and the left valve flap and the right valve flap are connected with each other by an elastic pulling rod mechanism driven by a cam. The continuous-flow three-way shifting valve has reasonable structure; a cam rotating shaft is adopted; the pulling rod is used for positioning and the valve flap is used for guiding; the valve flap can move left and right by rotating a camshaft, thus leading a left interface and a right interface to be opened and closed; the unique end surface sealing design structure is adopted, thus achieving zero leakage theoretically; furthermore, a sealing ring does not fall off or loosen; a spring is adopted for pre-tightening and compacting, thus compensating the machining precision; and the steering operation is flexible, the friction resistance is less, the circulating area is large, and the openness of the valve can be adjusted by a pointing pin.
Description
Technical field:
The utility model relates to a kind of three-way switch valve.
Background technique:
Existing three-way switch 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 three-way switch valve.
Technical solution of the present utility model is:
A kind of conveyance fluid continuous flow three-way switch valve, comprise that house steward, a left side are taken over, the right adapter, it is characterized in that: spool is set in house steward, left side adapter, the right confluce of taking over, 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 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 cam rotation axle, and locatees with pull bar, and 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.Can be widely used in the system of fluids such as water, lubricant oil and emulsified liquid, be and duplex cooler and the supporting better selection of duplex strainer.
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.
Embodiment:
A kind of conveyance fluid continuous flow three-way switch valve, comprise house steward 1, left side adapter 2, right adapter 3, in house steward, left side adapter, the right confluce of taking over spool is set, the left flap 4 of spool, right flap 5 stretch into left side adapter 2, the right adapter in 3 respectively, the elastic draw bar mechanism connection that left flap, right flap drive by cam 6.
The elastic draw bar mechanism of described cam driven comprises left and right cam pressing plate 7,8, between the left and right cam pressing plate cam 6 is set, left and right pressing plate is connected with right connecting plate 11, left connecting plate 12 by left and right pull bar 9,10 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 13, 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 14, and right stage clip is fitted on the right flap.In outer end, left and right flap bottom seal ring 15,16 is set.Equilibrium valve 17 is set between the left and right adapter.Cam is connected with sensing pin 18, points to the pin both sides left and right sides locating stud 19,20 that limits sensing pin left-right rotation position is set.Point to pin and be arranged on commutation direction board 21 tops.
During the utility model work, by rotatingshaft 22 rotating cams 6, because the flap of the left and right sides connects by pull bar elasticity, when rotatingshaft 22 turns left, drive right flap by cam 6 and right pull bar and move right, and left flap also moves right, the result takes over a left side and is unlocked, and right the adapter closed; Otherwise, when rotatingshaft 22 turns right, drive left flap by cam 6 and left lever 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 17 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.
