Abstract

The utility model relates to a three-way ball valve. The symmetrical ball valve is mainly composed of a valve body, a valve core, a connecting rod and a handle. The valve body has three pipelines. There are three through holes in the valve core, and the axes of the three through holes form an angle of 120 degrees in pairs on the plane, and the three through holes communicate with each other and are connected with the diameter of the three branch pipelines. same. The handle can be rotated counterclockwise or clockwise arbitrarily continuously or back and forth, driving the valve core to rotate, which can fully open the three pipelines, so that the mixed medium can quickly and easily flow to the pipeline with the lowest pressure; it can also make the three pipelines Fully closed, switching between on and off is quick and efficient.

Description

The symmetry ball valve

Technical field

The utility model relates to a kind of tee ball valve, particularly a kind of symmetrical ball valve with jet function.

Background technique

Existing closed cycle pipe-line system no matter be water pipe, tracheae or hot water heating pipe, always adopts the common tee pipe fitting with a kind of structure, sees shown in the structural material handbook.But in practice, because the pressure of different pipeline internal mediums, promptly pipe is pressed or the resistance difference, the pressure loss that just produces in the pipeline when different pipeline internal mediums crosses is managed damage, make energy cancel out each other, the pipeline of pressure maximum hampers the proper flow in other pipeline tributary, has reduced the efficient of pipe-line system fed sheet of a media.Toilet water tank in daily life is also like this, because the limited discharge pressure of water tank volume is also limited, but people always wish that toilet has higher hydraulic pressure and big amount of flush water.

Summary of the invention

In order to address the above problem, the utility model provides a kind of symmetrical ball valve according to the fluidics principle, make full use of each pipeline pressure energy, making each pipeline pressure is not to offset but introduce mutually to promote, the pipeline internal medium introduction that is the pressure maximum is promoting the medium pipeline internal medium of other pressure, and the medium that their are mixed is carried smoothly apace to the duct orientation of pressure minimum.

The scheme that the utility model adopted is:

The symmetry ball valve mainly is made of valve body, spool, connecting rod and handle, have three bye-passes on the described valve body, the axis two twenty percents 120 degree angles of described in the plane three bye-passes, have three through holes in the described spool, the axis two twenty percents 120 degree angles of described in the plane three through holes, described three through holes communicate in twos and are identical with the diameter of described three bye-passes.Described connecting rod is connected with spool, can adopt existing processing technique to realize, described handle can be counterclockwise or is rotated continuously arbitrarily clockwise or rotate back and forth, drive valve core rotation by rotatable handle, can make three bye-pass full open, make mixed medium flow to a bye-pass of pressure minimum fast, easily.Also can make three bye-pass contract fullys.

The beneficial effects of the utility model are:

The symmetry ball valve is to utilize the fluidics principle, can make the pipeline internal medium introduction of pressure maximum promote the medium pipeline internal medium of pressure, makes mixed medium flow to a branch pipe(tube) of pressure minimum fast, easily, and flow is big, pipe decreases little.Three bye-passes are full open or contract fully simultaneously simultaneously, switch between the Push And Release rapidly and efficient high.

Description of drawings

Further specify below in conjunction with figure of the present utility model:

Fig. 1 is described symmetrical ball valve tectonic maps, is the B-B sectional drawing of Fig. 2;

Fig. 2 is described symmetrical ball valve tectonic maps, is the A-A sectional drawing of Fig. 1.

Among the figure, 1. connecting rod, 2. handle, 3. spool, 4. valve body.

Embodiment

Symmetrical ball valve tectonic maps as described in as Fig. 1, as Fig. 2 being, mainly constitute by valve body, spool, connecting rod and handle, described valve body has three bye-passes on (4), the 120 degree angles, axis two twenty percent planes of described three bye-passes, have three through holes in the described spool (3), the 120 degree angles, axis two twenty percent planes of described three through holes, described three through holes are identical with the diameter of described three bye-passes.Described connecting rod (1) is connected with spool, drives spool (3) by rotatable handle (2) and rotates, and can make three bye-pass full open, makes mixed medium flow to a bye-pass of pressure minimum fast, easily.

Embodiment: described symmetrical ball valve is applied to patent of invention " jet flow cistern for toilet " 200610147158.7, a bye-pass directly can be connected running water pipe, a bye-pass connects the water inlet of water tank, and a bye-pass connects the water outlet of water tank.During use, described symmetrical ball valve is in opening state, at this moment two strands of current that just have two bye-passes inject simultaneously, and another bye-pass that the rapidly big flow ground of setting-out injected low pressure during high pressure water was introduced and to be promoted is the water outlet of water tank, wash current rapidly, the time is very short.Because described symmetrical ball valve can be closed rapidly and good airproof performance, radiator leak seldom makes and stays the water yield seldom in the toilet, like this energy using water wisely total amount again.

Claims

1. symmetrical ball valve, mainly constitute by valve body, spool, connecting rod and handle, it is characterized in that: have three bye-passes on the described valve body, the axis two twenty percents 120 degree angles of described in the plane three bye-passes, have three through holes in the described spool, the axis two twenty percents 120 degree angles of described in the plane three through holes, described three through holes communicate in twos and are identical with the diameter of described three bye-passes.
