Abstract

The utility model discloses a ball valve, in particular to a three-way ball valve, which comprises a valve body (1) and a valve core (2), and a connecting passage, both ends of which are open, is arranged in the valve core (2). As the valve core (2) rotates, an orifice (3) of the valve body (1) can be opened or closed by means of the connecting passage (4) of the valve core (2), any radial cross section of the connecting passage (4) is a round according with the inner diameter of the orifice (3), and the normal angle between the radial cross sections of the openings of both ends of the connecting passage (4) is larger than 90 degrees. The ball valve can prevent blockage, ball-passing cleaning can be conveniently carried out, the phenomena of turbulence and cavitation can be prevented, and the ball valve can be used to shunt, converge and mix the flow of media such as gas, liquid and powder in the process of production in industries such as petroleum, petrochemical, chemical industry, water treatment and tank fields.

Description

Tee ball valve

Technical field

The utility model relates to a kind of ball valve, especially a kind of tee ball valve.

Background technique

In industry production technologies such as oil, petrochemical industry, chemical industry, water treatment, tank field, when the shunting of media such as needs realization gas, liquid, powder, interflow, mixed flow requirement, can select the requirement of satisfying this technology of tee ball valve usually.Present tee ball valve, the connecting passage of its spool generally has two kinds of structures: T type and L type, the corner of T type and L type connecting passage all is 90 ° of right angles, the medium that is transferred is broken up at the right-angled corner place easily, the quality of the product that damages is also easily on the corner piled up to form and is stopped up, the connecting passage at other 90 ° of right angles can not lead to the ball operation, so T type and L type tee ball valve can not use logical ball mode to carry out duct cleaning.

The model utility content

In order to overcome existing deficiency, technical problem to be solved in the utility model provides a kind of can preventing and stops up and logical ball operation cleanser conduit tee ball valve easy to use.

The technological scheme that its technical problem that solves the utility model adopts is: tee ball valve, comprise valve body and spool, be provided with the connecting passage of both ends open in the described spool, rotation with spool, the connecting passage of the mouth of pipe of valve body by spool is communicated with or closes, any radial cross section of described connecting passage all is the circle consistent with spout diameter, and the normal direction angle of its both ends open radial cross section is greater than 90 °.

As a kind of preferred version, the normal direction angle of described connecting passage both ends open radial cross section is 120 °～135 °.

The beneficial effects of the utility model are: connecting passage adopts the wide-angle design, the connecting passage of ball valve is consistent with the aperture of pipeline, and its any radial cross section all is the circle consistent with spout diameter, therefore it axially is slick and sly design, significantly reduces flow resistance, avoids the generation of turbulent flow, cavitation phenomenon, the medium that is transferred can be not destroyed in slick and sly connecting passage, prevent to stop up, and can lead to the ball operation, be convenient to through normal open ball cleanser conduit.

Fig. 2 is embodiment two a structural representation.

Embodiment

Below in conjunction with accompanying drawing the utility model is further specified.

As shown in Figure 1, tee ball valve of the present utility model, comprise valve body 1 and spool 2, be provided with the connecting passage of both ends open in the described spool 2, rotation with spool 2, the connecting passage 4 of the mouth of pipe 3 of valve body 1 by spool 2 is communicated with or closes, and any radial cross section of described connecting passage 4 all is and the consistent circle of the mouth of pipe 3 internal diameters that the normal direction angle of its both ends open radial cross section is greater than 90 °.

Connecting passage 4 adopts the wide-angle design, the connecting passage 4 of ball valve is consistent with the internal diameter of pipeline, the mouth of pipe 3, and its any radial cross section all is and the consistent circle of the mouth of pipe 3 internal diameters, therefore it axially is slick and sly design, significantly reduces flow resistance, avoids the generation of turbulent flow, cavitation phenomenon, the medium that is transferred can be not destroyed in slick and sly connecting passage 4, prevent to stop up, and can lead to the ball operation, be convenient to through normal open ball cleanser conduit.

As a kind of preferred version, the normal direction angle of above-mentioned connecting passage 4 both ends open radial cross sections is 120 °～135 °.When the normal direction angle of connecting passage 4 both ends open radial cross sections was lower than 120 °, effect was not ideal enough; Need switching channel when using owing to tee ball valve simultaneously, when therefore the normal direction angle of connecting passage 4 both ends open radial cross sections is 135 °, adjacent nearest two mouths of pipe, 3 axis angles have only 90 °, therefore when its during greater than 135 °, may influence the setting of the mouth of pipe 3.

Further, the mouth of pipe 3 of above-mentioned valve body 1 is a demountable structure, and the axis of the described mouth of pipe 3 is straight line, broken line or arc.Removably connecting can be that flange connects, also can be that annular snap links and connects etc.Because the layout of on-the-spot process pipe must could be connected with the mouth of pipe 3 according to the position of pipeline port, limited at the scene space lining is put process pipe just significant limitation, adopt the restriction of the mouth of pipe 3 energy root site space of detachable structure, rationally use straight tube, bend pipe to satisfy the requirement of on-the-spot arrangement technology pipeline, on-the-spot limited space is used more effectively.

Embodiment one

As shown in Figure 1, tee ball valve, comprise valve body 1 and spool 2, be provided with the connecting passage of both ends open in the described spool 2, rotation with spool 2, the connecting passage 4 of the mouth of pipe 3 of valve body 1 by spool 2 is communicated with or closes, and any radial cross section of described connecting passage 4 all is and the consistent circle of the mouth of pipe 3 internal diameters that the normal direction angle of its both ends open radial cross section is 120 °.The mouth of pipe 3 of valve body 1 is a demountable structure, connects by flange, and wherein two mouths of pipe 3 are that axis is the bend pipe of broken line, and another is the straight tube of straight line for axis.

Embodiment two

As shown in Figure 2, tee ball valve, comprise valve body 1 and spool 2, be provided with the connecting passage of both ends open in the described spool 2, rotation with spool 2, the connecting passage 4 of the mouth of pipe 3 of valve body 1 by spool 2 is communicated with or closes, and any radial cross section of described connecting passage 4 all is and the consistent circle of the mouth of pipe 3 internal diameters that the normal direction angle of its both ends open radial cross section is 135 °.The mouth of pipe 3 of valve body 1 is a demountable structure, connects by flange, and wherein two mouths of pipe 3 are that axis is the bend pipe of broken line, and another is the bend pipe of arc for axis.
