Abstract
The utility model relates to a three-way valve, two inlets and one outlet are arranged on a valve body. The utility model is characterized in that: an inner pipe is arranged in the valve body, two ends of the inner pipe are provided with liquid discharge holes, a plunger piston is arranged in the inner pipe. The utility model has the advantages of control in place of the valve body, good sealing performance and long service life.
Description
Technical field
The utility model relates to a kind of mechanical part, especially a kind of three-way valve.
Background technique
Its valve body of general in the market three-way valve adopts ball valve control, yet after a period of time use, ball valve control can be not in place, and sealing is with great difficulty leakage, causes work pause bayonet socket, reduces working efficiency.
Summary of the invention
At above-mentioned existing problems, the utility model provides a kind of three-way valve, adopts new working method, and valve body control puts good seal performance, long service life in place.
In order to reach above purpose, the utility model is taked following technological scheme, and a kind of three-way valve, valve body are provided with two imports and an outlet, it is characterized in that: described valve inner has pipe in, and the two ends of interior pipe are provided with liquid outlet opening, and there is a plunger inside of interior pipe.
Because the utility model relates to and taked above technological scheme, has the following advantages: valve body control puts good seal performance, long service life in place.
Description of drawings
Fig. 1 executes routine structural representation for an example of the present utility model
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment one
As shown in Figure 1, a kind of three-way valve that the utility model relates to, the two ends of three-way valve valve body 1 are provided with two imports (import 2 and import 3), valve body 1 outer wall middle part is provided with outlet 4, there is pipe 5 in a valve body 1 inside, the two ends of interior pipe 5 are provided with liquid outlet opening 6, and there is a plunger 7 inside of interior pipe 5, and the two ends of plunger 7 are provided with buffer gasket 8 (buffer gasket 8 also can be arranged on import and plunger contacting point).
Working procedure is as follows: when the high-pressure gas-liquid mixture (also can enter from import 3 earlier when import 2 enters at work, but can not enter simultaneously, here our hypothesis is introduced into from import 2), plunger 7 is pushed to import 3 one ends, thereby the liquid outlet opening 6 of sealing import 3 and import 3 ends, the high-pressure gas-liquid mixture is gushed out from the liquid outlet opening 6 of import 2 ends and is entered in the valve body 1, and goes out by exporting 4; When enter from import 2 the high-pressure gas-liquid mixture all from export 4 discharge after, there is the high-pressure gas-liquid mixture to enter simultaneously from import 3, plunger 7 is pushed to import 2 one ends, thereby the liquid outlet opening 6 of sealing import 2 and import 2 ends, the high-pressure gas-liquid mixture is gushed out from the liquid outlet opening 6 of import 3 ends and is entered in the valve body 1, and goes out by exporting 4; Periodic duty so goes round and begins again.
In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
Claims (2)
1. three-way valve, valve body is provided with two imports and an outlet, it is characterized in that: described valve inner has pipe in, and the two ends of interior pipe are provided with liquid outlet opening, and there is a plunger inside of interior pipe.
