Description

Three-way ball valve

A kind of hot and cold water that is used for mixes water supply, and the tee ball valve of heating and energy saving and industrial pipeline belongs to building hot-water heating valve field.

Present hot and cold water the mixings water supply valve accessory that uses of building toilet, low-grade two stop valves of usefulness are set up the hot and cold water flow respectively, regulate very inconveniently, and cause the waste of water, and the cold and hot mixing water that the use ceramic component of top grade is assembled is chewed the manufacture cost height.

While northern China building winter heating system, according to the building code requirement, big portion adopts the single tube radiator heat supply that is installed in series, hot water toward the low heat radiation of flowing, makes high level different with the hot water temperature of low layer along floor from height, causes the floor heat supply temperature difference big, for the heating three-way cut-off valve form structure that addresses this problem supply the market old-fashioned, complex manufacturing, resistance is big, can not satisfy the demand.

The purpose of this utility model provides a kind of novel three-way ball valve, and both can be used for building toilet hot and cold water and mixed water supply, and easy to adjust, can limit water consumption; Also can be used for the building hot water system, simple in structure, reliable operation.

Used technological scheme is in a valve body that three through holes are arranged, install the ball core of useful valve pad sealing, the hole that three intercommunications are arranged on the ball core, wherein two axis are mutually acute angle, the 3rd hole (hole under the ball core) axis is vertical with plane, axis place, the first two hole (ball core mider hole), three centerline holes meet at a bit, the 3rd hole forever aligns a through hole of valve body lower portion, the valve rod that connects hand wheel is positioned at the top of valve body, the axis of valve rod overlaps with the 3rd axially bored line, when rotating handwheel, the ball core is rotated around the 3rd axially bored line, thereby change first, two holes align the folding degree of all the other two through hole of valve body, make two holes obtain identical or different inflow (or water-outlet quantity).

The tee ball valve that the utility model provides (threeway ball cored structure principle) has simple in structure, reliable operation, and good seal is handled advantage easy to use, compares with the water heating fittings of existing congenerous, and its manufacture cost is lower.

This specification has following accompanying drawing:

Fig. 1 is the tee ball valve positive view;

Fig. 2 is the plan view of ball core;

Fig. 3 is the 3-3 sectional view of Fig. 1, and the ball core is in two hole standard-sized sheets, a hole full close position;

The same Fig. 3 of Fig. 4, the ball core is in the position that three holes are all connected.

Now in conjunction with the accompanying drawings.

Tee ball valve is by valve body 1, valve gap 2, spool 3, sealing gasket 4,5, valve rod 6, handwheel 7, O RunddichtringO 8,9 is formed, and sees Fig. 1, and horizontal through hole 10 and vertical through hole 11 are arranged on the valve body, valve gap 2 usefulness screw threads and valve body connect as one, and the center line of the center line of the through hole 12 on the valve gap 2 and the through hole 10 of valve body 1 coincides; Ball core 3 is contained in the cavity of valve body 1 and valve gap 2 formation, aligning through hole 10 and 12 places has sealing gasket 4,5 and ball core 3 to constitute the elastic compression sealing respectively, sealing gasket 4,5 usefulness elastic wear-resistings, heat-resisting material for example teflon are made, three holes that interconnect 13,14,15 are arranged on the ball core 3, hole 13 and 14 center line are in an acute angle, the center line in hole 15 is vertical with the plane, center line place in hole 13,14, and three centerline holes meet at any and see Fig. 2.Valve rod 6 is contained in the circular hole above the valve body 1, make it sealing with O type O-ring seal 8, the center line of the center line in the hole 15 of the center line of valve rod 6 and ball core 3 and the through hole 11 of valve body 1 coincides, the tang of valve rod 6 ends inserts in the groove 16 of ball core 3, can stir ball core 3 rotates, when the ball core rotated, hole 15 aligned the through hole 11 of valve body 1 all the time.

In best design, the aperture of two through holes 13,14 of ball core 3 is identical, and identical with the aperture of the through hole 10,12 of valve body 1 valve gap 2, and the aperture of the through hole 15 of ball core 3 is identical with the aperture of valve body 11.When this tee ball valve was used for hot and cold water and mixes, the through hole 13 of ball core 3 and 14 center line angle α were 110 °-115 °; When being used for hot water system, angle α is between 130 °-140 °.

Fig. 3 Fig. 4 is used for hot and cold water mixing schematic representation for tee ball valve, and Fig. 3 shows water intake 10 standard-sized sheets, water intake 12 full close positions, and water flow path hole 10 enters at this moment, and 11 flow out through the hole.Fig. 4 shows that water intake 10 and 12 is half-open, and the hot and cold water hole 10 and 12 of flowing through flows into respectively, and 11 flow out through the hole.Because the different increase and decreases of two water inlet aperture folding degree, the water yields that make 11 outflows through the hole are near constant.

When tee ball valve was used for heating system, hole 11 was the water inlet, a connection radiator inlet duct in the hole 10 and 12, and another connects water arm down, makes the part of water supply directly enter next floor.(schematic representation is omitted).
