Abstract

The utility model discloses a temperature adjusting three-way ball valve whose structure mainly comprises a valve seat (1), a valve core, a valve cover (23) and an operating handle (25), wherein, the valve seat (1) is composed of a hot water inlet pipe head (2), a cold water inlet pipe head (3) and a water outlet tap (4), and the valve core is composed of an upper half outer ball casing (20), a lower half outer ball casing (8) with a hole and an inner ball casing (16). The temperature adjusting three-way ball valve adopts the method that the utility model is fixed by an outer ball casing, and a hollow inner ball casing slides relatively in the outer ball casing to regulate the water output temperature and the water output quantity, and the regulation is rapidly finished just by using one operating handle, which causes the operation to be convenient and saves time and water. The utility model has the advantages of simple structure and low cost, which can be widely used for matching with the devices of the toilets of guesthouses, hotels and households.

Description

Temperature adjusting three-way ball valve

The utility model relate to a kind of all movably sealing surface specifically be meant a kind of temperature adjustment tee ball valve of the shape cock of dribbling as the mixing valve of a cell moving.

Existing a large amount of temperature adjustment three-way valve, all be to finish the proportions of ingredients control and the water flow size of hot water and cold water and control by operating two or three valve handles or knob, thereby complex structure, cost is higher, and troublesome poeration, the water yield is suitable often, and water temperature is improper again, and perhaps situation is opposite.Transfer to the both and close the symbol requirement, often will repeatedly move handle or knob repeatedly, be difficult to just the water temperature and the water yield are transferred to desirable degree quickly.Particularly under the situation of variation in water pressure, then regulate more difficult.Also have by operating a valve handle and finish the temperature adjustment three-way valve of above-mentioned control easily, but still exist complex structure and the high problem of cost, be difficult to penetration and promotion.

The purpose of this utility model is to provide a kind of proportions of ingredients and the temperature adjustment tee ball valve water flow size, simple in structure and cheap that can regulate hot water and cold water easily.

Solution of the present utility model is as follows.It has a band water inlet of hot water tube head, the valve seat of cold water inlet tube head and depotition cock, on valve seat, have uncovered spool bore, tightly be with one in the hole and have water inlet of hot water, the outer spherical shell of second of cold water inlet and water outlet, valve seat inside have an end respectively with the water inlet of hot water tube head, cold water inlet tube head and depotition cock are connected, and the other end respectively with the water inlet of hot water of second outer spherical shell, the hot water inlet hole that cold water inlet and water outlet are connected, cold water inlet hole and leading water inlet, and seal ring all is equipped with by an end of second outer spherical shell in these three holes, the spherical shell inner sliding sleeve an interior spherical shell that has connecting rod and have water inlet and osculum outside second, having a pair of on the meridian plane of interior spherical shell is the chute of symmetry center with the centre of sphere, all place the arc shaped slider of a center band roundlet pin in each chute, above valve seat, have one slide in spherical shell outside first of the spherical shell first half, first outer spherical shell is connected mutually with valve seat, and and be lined with seal ring between valve seat and second the outer spherical shell, roundlet pin on two arc shaped sliders is sliding respectively to be inserted in two pin-and-holes that the merging of being offered by first outer spherical shell and second outer spherical shell forms, first outer spherical shell top is fixed with the valve bonnet that it is covered, all have the opening of doing motion for the connecting rod of interior spherical shell on valve bonnet and first outer spherical shell, connecting rod stretches out outside the opening and with an operating grip and is connected mutually.

The utility model with said structure when mounted, water inlet of hot water tube head on the valve seat and cold water inlet tube head are joined with the hot water feeding pipe and the cold water water pipe in the external world respectively, just can make hot water and the cold water hot water inlet hole on valve seat and cold water inlet hole and arrive the water inlet of hot water and the cold water inlet of spherical shell outside second respectively respectively.Only need during use operating grip is up lifted a bit gently, make leading water outlet, (or to the right) moves handle then left, transfers to suitable water temperature, more up (or down) move handle, transfer to the water yield size of hope.When closing, handle is down got to limit position get final product.

During limit position under operating grip is in, stagger in the water inlet of the water inlet of hot water of second outer spherical shell and cold water inlet and interior spherical shell, the water outlet of second outer spherical shell and the osculum of interior spherical shell also stagger, and this moment, the water route was blocked by interior spherical shell, and valve is in closed condition.When with operating grip when closed position is upwards lifted gently, spherical shell is done the rotation of the roundlet pin on arc shaped slider in driving, promptly slide along making progress through the plane with respect to outer spherical shell, so make the water inlet of hot water of second outer spherical shell and cold water inlet all open-minded towards the water inlet of interior spherical shell, the water outlet that makes second outer spherical shell is simultaneously partly opened or all open-minded towards the osculum of interior spherical shell, thus have water on interior spherical shell and valve seat leading water inlet and flow out from tap.On this basis, the left and right handle of moving, spherical shell is along the slip of arc shaped slider do with respect to outer spherical shell in making, change water inlet of hot water on second outer spherical shell and cold water inlet and open the area ratio towards the open and-shut mode of the water inlet of interior spherical shell and both, just the hot water amount of spherical shell inside and the ratio of cool water quantity in can regulate enters, hot water and the cold water warm water after interior spherical shell internal mix flows out from tap.Again on this basis, the upper and lower handle of moving, spherical shell is done with respect to outer spherical shell along the upper and lower slip through the plane in making, and the water outlet that changes second outer spherical shell is towards the area of opening of the osculum of interior spherical shell, so just regulated from the warm water water yield size of tap outflow.This moment since water inlet of hot water on second outer spherical shell and cold water inlet towards the water inlet of interior spherical shell open area than constant, the hot water amount of spherical shell and the ratio of cool water quantity do not change in therefore entering, so the only big or small change of the water yield and water temperature is constant.

The utility model is only used an operating grip, just can regulate the proportions of ingredients and the water flow size of hot water and cold water soon, makes easy to operately, saves time and using water wisely.Especially different and when changing to some extent when the pressure of institute's heat supply water and cold water, use the utility model just more to see the convenience of its operation.Its structure not only heat control valve with two or three operating grips or knob than present common use is much simple, and it is also simple to have a heat control valve of making the operation handle than existing.Thereby its cost cost is lower, is easy to generally promote.It can be extensively and the sanitary equipment of hotel, hotel and family supporting.
