Embodiment

In order that those skilled in the art more fully understands the technical solution of the utility model, below in conjunction with the accompanying drawings and tool The utility model is described in further detail for body embodiment.

As shown in Figure 1 to Figure 3, a kind of triple valve, including valve body 1 and valve element 2, the circumferentially distributed of the valve body 1 have three Interface, including first interface 3, the interface 5 of second interface 4 and the 3rd, specifically, the first interface 3 is emulsion entrance, it is described Second interface 4 is cleaning liquid inlet, and the 3rd interface 5 is liquid outlet, the first interface 3 and the second interface 4 Coaxially, the central axis of the 3rd interface 5 is in the center line of the first interface 3.

The valve element 2 for it is cylindric and it is mobilizable be inserted in valve body 1, the valve element 2 be provided with and the first interface 3rd, the corresponding hole of 4 and the 3rd interface of second interface 5, the end face of the bottom of valve element 2 is provided with prominent limited block 6, the valve Spring 8 is provided between the bottom of core 2 and valve body 1.

It is additionally provided with the valve body 1 in shoulder hole 7, the shoulder hole 7 and is placed with spring 8, spring 8 is located at the bottom of valve element 2 Capping 9, the capping are additionally provided with the centerline collineation of the center line of portion and the spring 8 and the valve element 2, the valve body 1 The spring 8 is fixed in valve body 1, sealing ring 10 is additionally provided between the capping 9 and valve body 1.

A kind of triple valve disclosed in the present application has the first operating position and the second operating position, and the spring 8 is uncompressed When be the first operating position, as shown in Fig. 2 the valve element 2 connects the first interface 3 with the 3rd interface 5, general simultaneously First interface 3 completely cuts off with the second interface 4.

It is second operating position when spring 8 compresses completely, as shown in figure 3, the valve element 2 connects 4 by described second Connected with the 3rd interface 5, the first interface 3 completely cuts off with the 3rd interface 5.

Triple valve disclosed in the present application is used for spray gun, and the spray boom and shower nozzle of spray gun are cleaned, with the first work Position and the second operating position, the first operating position are the operating position under spring normal condition, and valve element is by the first interface With the 3rd orifice, while first interface and the second interface are completely cut off, emulsion is entered through from first interface Valve element flows out to spray gun from the 3rd interface, realizes the normal spraying function of spray gun, when spraying is finished, by pressing valve element to bullet Spring compression completely switches to the second operating position, i.e., described second interface and the 3rd orifice, the first interface with 3rd interface isolation, cleaning fluid enters through valve element from the 3rd interface through second outlet and flows out to spray gun, emulsion and the Three interfaces completely cut off, and because cleaning fluid is the liquid with pressure, are sprayed through the above way out of spray gun, so as to remove in spray gun The emulsion residue in portion, realizes the cleaning of spray gun.
