Background technique
Three-way control valve is widely used in the various occasions of city hot water heating, and it is to reach and regulate ambient temperature, energy efficient and by regulating the current direction that changes medium to reach purpose such as each branch road circulation by regulating flow.Because traditional ball valve type three-way valve flow is little, the yielding leakage of valve seat, and defective such as ball valve class valve can only be made standard-sized sheet or complete shut-down uses, and can not regulate flow, has a strong impact on the heating effect of system, causes utilization ratio in actual the use, and energy consumption is big.Chinese patent ZL92204761.8 discloses a kind of triple valve, has the criss-cross valve body that an import and two outlets are wherein arranged, its import is connected with the outlet of concentricity line by the valve seat orifice in next door, import also is connected by the interior vertical outlet that valve seat is housed, the plate valve of turn on the turn valve rod termination on the valve body is housed between valve seat orifice on the valve body and the hole on the valve seat, this technological scheme is better than the effect of ball valve, but structure is compact inadequately in actual the use, mounting distance is long, and degree of regulation is also not high enough.
Summary of the invention
The purpose of this utility model is the design three-way control valve that a kind of compact structure is reasonable, mounting distance is short, using effect is good.The technical solution of the utility model is so to realize:
A kind of three-way control valve, comprise valve body, valve rod by adjusting handle control, valve rod and flap link, valve body is provided with medium import, first media outlet and second media outlet, the axial direction of valve rod is provided with first valve seat mouth that is communicated with first media outlet and medium import and the second valve seat mouth that is communicated with second media outlet and medium import, flap places between the first valve seat mouth and the second valve seat mouth, flap (6) is made up of orthogonal flap bar (26) and flap head (36), and flap bar (26) is connected with valve rod (10) by screw thread; The second valve seat mouth (11) is located on the horizontal spacer (33) that the back spacer (32) of the preceding spacer (31) of nearly medium import (7) in the valve body (2) and nearly second media outlet (21) links, horizontal spacer (33) is provided with valve seat orifice (30), preceding spacer (31) and back spacer (32) are coaxial garden arc structure, and axis is consistent with flap bar (26) axis.
As preferably, preceding spacer (31), back spacer (32) and horizontal spacer (33) and valve body (2) are into a single integrated structure.
As preferably, flap head (36) outside on the flap (6) is provided with a sealing layer (16), and flap bar (26) becomes the inverted T-shape structure with flap head (36).
As preferably, be provided with into positioning guiding structure (29) between flap (6) and the valve body (2), positioning guiding structure (29) is that the one group of projection (19) that is provided with on the sealing layer (16) of one group of chute (18) and flap head (36) by valve body (2) constitutes.
The utlity model has compact structure, easy for installation, characteristics such as effect is good, be easy to apply.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing,, the technical solution of the utility model is described in further detail by embodiment.
Embodiment: in conjunction with the accompanying drawings 1, the valve body of three-way control valve (2) is provided with medium import (7), first media outlet (22) and second media outlet (21), valve rod (10) one ends are by adjusting handle (12) control of band scale, the other end links by screw thread and flap (6), valve rod (10) bottom peripheral hardware valve gap (9), valve gap (9) is integral by screw thread and valve body (2), is provided with seal ring (8) between valve gap (9) and valve rod (10) bottom; In valve body (2) inside, the axial direction of valve rod (10) is provided with the first valve seat mouth (41) that is communicated with first media outlet (22) and medium import (7) and is communicated with the second valve seat mouth (11) of second media outlet (21) and medium import (7), and the first valve seat mouth (41) overlaps in first media outlet (22) and valve body (2) formation by being located at; Flap (6) is made up of orthogonal flap bar (26) and flap head (36), become the inverted T-shape structure, place between the first valve seat mouth (41) and the second valve seat mouth (11), flap bar (26) is connected with valve rod (10) by screw thread, flap head (36) outside on the flap (6) is provided with a sealing layer (16) of being made by HPb59-1 fourth rubber material, this material is through the vulcanizing treatment adhesion-tight, strengthened wear-resistingly, ageing-resistant, also be provided with one group of projection (19) on the sealing layer (16) of flap head (36).Nearly medium import (7) is provided with preceding spacer (31) in the valve body (2), nearly second media outlet (21) is provided with back spacer (32), before spacer (31) with afterwards link to each other by horizontal spacer (33) between the spacer (32) perpendicular to valve rod (10), horizontal spacer (33) is provided with valve seat orifice (30), constitute the second valve seat mouth (41) thus, flap head (36) passes valve seat orifice (30), and external diameter is greater than valve seat orifice (30) internal diameter, preceding spacer (31), back spacer (32) and horizontal spacer (33) are into a single integrated structure with valve body (2), preceding spacer (31) and back spacer (32) are coaxial garden arc structure, and axis is consistent with flap bar (26) axis; Valve body (2) is provided with one group of chute (18), one group of projection (19) on the sealing layer (16) of chute (18) and flap head (36) constitutes positioning guiding structure (29), make flap (6) at the first valve seat mouth (41) to moving easily between the second valve seat mouth (11).
