Abstract

The utility model discloses a three-way ball core valve which is composed of a three-way pipe, an outer pipe I and an outer pipe II of the three-way pipe, and a ball core, wherein the three-way junction part is a ball core chamber in which the ball core is arranged, the radius of the ball core is slightly larger than the inner radii of the outer pipe I and the outer pipe II and is slightly smaller than the internal radius of an inner pipe III. The three-way pipe can be clogged or opened by the movement of the ball core, namely the valve can be closed and opened. The utility model has the advantages of simple structure, small size and long service life.

Description

A kind of threeway ball core valve door

Affiliated technical field

The utility model relates to a kind of valve, particularly a kind of ball core valve door that connects together with threeway.

Background technique

Valve is used very extensive in pipework, valve commonly used is by valve body, spherical valve core, connecting rod, handgrip are formed, spherical valve core is installed in the body that makes a noise, handgrip connects together by connecting rod and spherical valve core, at through hole of spherical valve core system: during use, regulate the position of through hole on the spherical valve core by rotating handgrip, to reach the purpose of opening and closing valve, such structure can only make valve opening and closing in one direction; When in pipework, running into than complicated pipelines, when needing the switch of while two pipelines, just need at least 2 valves are installed, in the use, as requested, operator must open or close each valve respectively, and it is not too convenient to use.

Present stage particularly, the water resources deficiency, water is most important in the utilization, and the middle water that the family water source generally has the kitchen to discharge, the middle water that washing machine is discharged, and two road current water water reservoirs or enter toilet and still need two valves, valve is many so at home, and inconvenient operation.

The model utility content

In order to overcome the above-mentioned shortcoming and defect of existing valve, the utility model provides a kind of threeway ball core valve door, provides a kind of valve of new controlled water flow, with the Automatic Control of the disengaging people's of the water-filling that reaches life water storage aspect, sealing, exhaust factor; And, adapt to the needs of moisturizing facility with the structure of concentrating, small and exquisite volume, sensitive action more perfectly.

The technological scheme that its technical problem that solves the utility model adopts is: threeway ball core valve door is made of pipe, outer tube I, pipe II and ball core in the threeway, wherein the threeway confluce is ball core chamber, it is indoor that the ball core is placed on the ball core, its radius is slightly larger than the inside radius of outer tube I and outer tube II, the inside radius of pipe III in being slightly less than, can determine blocking up and opening of three-way pipe in conjunction with the motion of ball, promptly valve closes, opens.

The beneficial effects of the utility model are that the ball core three-way pipe of employing such scheme can realize the automatic control of water-filling, sealing, moisturizing, exhaust, and its volume is small and exquisite, simple in structure, long service life, and good use value is arranged.The middle water treatment valve that is particularly suitable for family expenses uses, and also can be applied to use on other valve of two tunnel logical one tunnel, does not need artificial treatment, just realizes crossing in order of current by natural flows fully.

Description of drawings

Fig. 1 is an overall structure schematic representation of the present utility model.

Fig. 2 is a stereogram of the present utility model.

Embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

Threeway ball core valve door as shown in Figure 1 and Figure 2, threeway ball core valve door is made of three-way pipe 1, outer tube I2, outer tube II3 and ball core 5, wherein the threeway confluce is ball core chamber 6, ball core 5 is placed in the ball core chamber 6, its radius is slightly larger than the inside radius of outer tube I2 and outer tube II3, and the inside radius of pipe III4 in being slightly less than can be in conjunction with the motion of ball, determine blocking up and opening of three-way pipe, promptly valve closes, opens.

As depicted in figs. 1 and 2, outer tube I2 in the three-way pipe 1 and the center line of outer tube II3 are concentric line, and vertical with the center line of interior pipe III4, and the radius of ball core 5 is slightly larger than the inside radius of pipe I2 and pipe II3, can control the break-make of two pipes completely.When water when outer tube I2 flows into, the impulse force of water promotes the bore place that ball core 5 moves to outer tube II3, there is lead angle 7 at the bore place, ball core 5 can be sealed whole bore fully, seals the path of outer tube II3, makes water pass through outer tube III4 and flows out; When water when outer tube II3 flows into, the impulse force of water promotes the bore place that ball core 5 moves to pipe I2, there is lead angle 7 at the bore place, ball core 5 can be sealed whole bore fully, seals the path of pipe I2, and water is flowed out by managing III4, reaches the purpose of automatic control.

The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.

Claims

1, a kind of threeway ball core valve door, it is characterized in that being made of the outer tube I in three-way pipe, the three-way pipe, outer tube II and ball core, wherein the threeway confluce is ball core chamber, and it is indoor that the ball core is placed on the ball core, its radius is slightly larger than the inside radius of outer tube I and outer tube II, the inside radius of pipe III in being slightly less than.

2, a kind of threeway ball core valve door as claimed in claim 1 is characterized in that the bore place of described outer tube I, outer tube II is equipped with lead angle.
