Abstract

The utility model relates to a fluid mixed valve, which is composed of a valve body, a cone valve core and a handle, wherein, the valve core can rotate following with the handle. The valve body has two inlet holes. The cone valve core has a hollow inner cavity. A cone wall is provided with two valve holes. The two valve holes and two inlet holes are arranged in misplacement to form a certain angle. Two fluids can simultaneously flow into the utility model through the two inlet holes. The two fluids can flow out after the two fluids enter the inner cavity of the valve core to be mixed. The opening degrees of valve holes are decided by the size of coincident surfaces between the valve holes and inlet holes. When the valve core is rotated, the open degrees of valve holes can be changed. When the open degree of one valve hole is enlarged, the open degree of the other hole is necessarily reduced, which is convenient to regulate the mixed ratio of the two fluids. The utility model is especially suitable for a water valve for a shower.

Description

Fluid mixed valve

The utility model relates to a kind of valve, particularly can flow into the fluid mixing valve of two fluid streams simultaneously.

Need be mixed into the occasion of fluid streams output with certain proportion for two fluid streams of carrying respectively by pipeline, two schemes that valve is connected with a threeway of general employing, the aperture that need regulate two valves respectively when changing the mixed proportion of two fluid streams, troublesome poeration, and install bothersome.Shower is exactly an example with the installation and the adjusting of the valve of hot and cold water in the daily life.

The purpose of this utility model provides a kind of fluid mixing valve, and it can make two fluid streams flow into simultaneously, and the proportions of ingredients of regulated fluid easily.

The utility model fluid mixing valve is made up of valve body, taper valve core and handle, spool can rotate with handle, and valve body has two ostiums, and taper valve core has hollow cavity, the awl wall has two valve openings, shifts to install with certain error angle between this two valve opening and two ostiums.Two fluid streams are fed by two ostiums respectively, and the inner chamber of going into spool through two valve openings mixes, and are flowed out by the outlet of valve.The rotation of spool can change the aperture of two valve openings, the aperture of valve opening depend on it with the valve body ostium between the size of the face that overlaps, coincidence face is big more, aperture is also big more.In the utility model, owing to shift to install between two ostiums and two valve openings, when therefore spool rotates, the increase and decrease trend of the coincidence face in two pairs of holes is opposite, when being the coincidence face increase of pair of holes, the coincidence face of pair of holes reduces in addition, changes the influx of two fluid streams according to this, reaches the purpose of regulating mixed proportion.

Adopt the fluid mixing valve of said structure, can feed two fluid streams simultaneously, and can change the flow of two fluid streams easily, a valve replaces two valves, reaches the purpose of regulating two fluid mixed proportions.This valve is particularly suitable for doing the shower water valve, can regulate hot water or cold water's flow easily and quickly, reaches suitable water temperature.

Below in conjunction with description of drawings example structure of the present utility model.

Fig. 1 is the B-B sectional drawing of the utility model fluid mixing valve.

Fig. 2 is the A-A sectional drawing of the utility model fluid mixing valve.

Shown in Figure 2 as Fig. 1, this valve is made up of valve body 4 taper valve cores 5 and handle 7, and valve body has ostium 3 ' and 7 ', and taper valve core 5 has hollow cavity 8, and the awl wall has two valve openings 3 and 7.In the present embodiment, the angle β between two

valve openings

3 and 7 the cross-section center line is less than 180 degree, and promptly two

valve openings

3,7 and two ostiums 3 ', 7 ' shift to install, and error angle α is about clear valve diameter to 1/2 of radian in the present embodiment.During shown position, valve opening 3 is identical with the aperture of valve opening 7, flows into inner chamber 8 from two fluid streams of

inlet union

2 and 6 with the ratio of 1:1 and mixes, and is flowed out by outlet connection 1.When pulling handle 9, make spool 5 when right rotation, valve opening 3 increases with the weight and the face of ostium 3 ', and valve opening 7 reduces with the weight and the face of ostium 7 ', thereby the influx of two fluid streams is changed.Make spool from shown position when the anticlockwise, effect is opposite.When a valve opening standard-sized sheet, another valve opening is complete shut-down just in time, and this moment, this valve only fed a fluid streams, and another plume amount is zero.

Claims

Fluid mixing valve is made up of valve body, taper valve core and handle, and spool can rotate with handle, it is characterized in that valve body has two ostiums, and taper valve core has hollow cavity, and the awl wall has two valve openings, shifts to install at a certain angle between this two valve opening and two ostiums.
