Abstract

The utility model belongs to a valve for mixing fluid which is used for mixing over two categories of fluid. The valve for mixing fluid is characterized in that the side of a valve body is arranged with over two mixed fluid inlet holes; the lower end of the valve body is provided with a mixing fluid outlet; a valve core is provided with inflow slots whose amount is same as the amount of the mixed fluid inlet holes; the proportion of the mixed fluid and the flow quantity of the mixing fluid are regulated through the axial direction and the circumferential direction positions of the valve core being changed. Compared with the existing mixing fluid technology, the utility model can replace over two valves to mix fluid, and the utility model has the advantages of convenient operation, arbitrary regulation of the proportion and the flow quantity of the mixing fluid.

Description

Valve for mixing fluid

The utility model belongs to mechanical engineering technical field, is a kind of mixing valve that is used to mix two or more fluids.

Existing water valve, can only pass through a kind of fluid, when needing two or more fluids to mix the back outflow, adopting two or more water valves to control respectively mixes, mix such as bathroom cold water and hot water (or steam), need to regulate cold valves and water valve respectively repeatedly, just can reach suitable water temperature and flow, operate complicatedly, regulate inconvenient.

The purpose of this utility model is that an a kind of valve of research can replace the mixing valve of two valves or many valves, two or more fluid can be carried out mixed flow with ratio arbitrarily, and can regulate the flow of fluid-mixing arbitrarily.

The technical solution of the utility model, be to comply with in the valve body side of one-way valve to be established plural inlet opening by the number of mixed flow body, establish the outlet of a fluid-mixing in valve body lower end, establish the inflow groove on the spool, its number equals valve body upper inlet hole number, by the axial position or the circumferential position of handle change spool, change the cross-sectional sizes of inlet opening and inflow groove valve port, realize two or more by any adjusting of the flow of the ratio of mixed flow body or fluid-mixing.

Further describe the structure characteristic of the utility model mixing valve in conjunction with the accompanying drawings with example.

Accompanying drawing is represented an exemplary construction schematic representation of the utility model mixing valve.

Referring to accompanying drawing, the utility model mixing valve mainly comprises handle 1, valve body 5, spool 6.The side of valve body 5 is provided with by mixed flow body inlet opening 7 with by mixed flow body inlet opening 8, and the lower end of valve body 5 is provided with fluid-mixing outlet 9; Handle 1 is connected with the valve rod of spool 6, and valve rod is fixing by the frictional force and the valve body 5 of adjusting nut 2, elastic ring 3, pad 4; The spool longitudinal section is n shape, on have and flow into groove 10,11, flute length is greater than wide, the wide diameter that equals inlet opening 7 and inlet opening 8, the layout that flows into groove 10,11 can have two kinds of schemes: first kind of embodiment as shown, two grooves circumferentially are staggeredly arranged to axial, and second kind of embodiment is that the two grooves axial same level that circumferentially staggers is arranged.Flow into groove 10,11 directly and the inlet opening 7,8 on the valve body join, passage is saved in the centre.The number that flows into groove number and valve body upper inlet hole on the utility model spool equals by the number of mixed flow body, and promptly number is more than two.

In illustrated first kind of example, when spool is in down extreme position, promptly groove 10 and inlet opening 7 be fully at once, at this moment has only a kind ofly to be entered in the valve by the mixed flow body, flows out from exporting 9; Twitch handle up and down, drive spool and move up and down, the change distance is during greater than slot length and wide difference, and a kind of valve port that is entered in the spool by the mixed flow body reduces gradually; Another kind of begun to open by the valve port of mixed flow body and increase gradually, two kinds are mixed by the mixed flow body, flow out from exporting 9; When spool changed distance greater than flute length, a kind of valve port of fluid was closed, and had only another kind to be flowed out from exporting 9 by valve port by the mixed flow body.In a word, move up and down spool, can regulate by the ratio of mixed flow body.Second kind of embodiment then is by the left-right rotation spool, regulates by the ratio of mixed flow body.

In first kind of embodiment, when needing to regulate the flow of fluid-mixing output, handle with sleeve 1, drive valve core rotation, the valve port overflow section in the inflow notch of spool and valve body upper inlet hole reduces gradually, and the flow that passes through is corresponding to be reduced, when spool forwards several angle to, valve port is closed, and is in current floe condition.Second kind of embodiment then is by moving up and down spool, regulating by the flow of mixed flow body.

Fixing of the circumferential position of spool and axial position all be fixing by means of the frictional force between valve rod and the elastic ring, and frictional force size available adjustment nut regulated, and elastic ring and pad play valve rod location and seal action.

This mixing valve of the present utility model is compared with existing mixed flow technology, has a valve and can replace many valves, and is easy and simple to handle, the advantage of regulating mixed flow ratio and flow arbitrarily.

Claims

1, a kind of mixing valve has valve body and spool, it is characterized in that being provided with in side of valve body plural by mixed flow body inlet opening, and valve body lower end is provided with the outlet of a fluid-mixing; The spool longitudinal section is n shape, be provided with and by the identical inflow groove of mixed flow body inlet hole count, by mixed flow body inlet opening directly and the inflow groove of spool join, save passage; Handle is connected with the valve rod of spool, and valve rod is fixing by adjusting nut, elastic ring and valve body friction.
