Description

Mixing and distributing valve

The utility model relates to the interflow valve, also relates to diverter valve.

In the past, in bathroom or Rest Room, the water-exit temperature of water tap normally by two separate, respectively be connected on cold water pipe, with hot-water line on valve, alternately regulate cold water and hot water flow ratio realization.The temperature adjustment troublesome poeration, and easily cause because open by mistake water valve earlier scalding.In some luxurious hotels, then be provided with pressure handle control water outlet, revolve a list that adjusts coolant-temperature gage the interflow valve, this interflow valve, structure is comparatively complicated, and price is higher, and still the scald accident takes place unavoidably.

In China, among the patent CN2033241U " hot and cold water list handle showering ", proposed new design: this valve is by the valve body that has hot water or cold water's water intake and mix (temperature) water water outlet, with constitute the spherical valve core of threeway with valve body is corresponding by two water intakes and water outlet, and other auxiliary spare part is formed.Because the spherical valve core processing difficulties is not only on the high side, and is difficult to adapt to higher pressure, in design, the water intake of this valve core is much smaller than the intake pipe caliber, and the pressure loss is bigger.Patent CN2038977U " temperature adjustment water is chewed ", this valve (water is chewed) will have now spool and valve body transform as double-deck, thereby realize regulating hot water or cold water's flow-rate ratio.This water is chewed, the structure more complicated, and processing is difficulty quite, poor slightly easy the leaking of machining accuracy.Combine to described, above-mentioned interflow valve has only special purpose, and withstand voltage properties is poor, and manufacture cost is higher.

The purpose of the utility model is: provide a kind of simple in structure, be easy to processing, the interflow that resistance to pressure and sealing are all good, shunting dual purpose valve design proposal and product.

The utility model is to realize above-mentioned purpose like this:

This interflow, shunting dual purpose valve (referring to Fig. 1, Fig. 2) are made up of valve body (1), spool (2), valve gap (3), handwheel or handgrip (14) and other auxiliary member.Valve body (1) becomes cylindricality, the perpendicular side direction interface of two axis and valve body central axis (4,5) is arranged on the cylinder, the bottom has an axis to coincide with the valve body central shaft or parallel longitudinal interface (6), and valve body top is the uncovered cylindrical cavity that can become to be slidingly matched with spool.It is cylindrical that spool (2) becomes, have two that interconnect, axis and center spool axis perpendicular and be mutually on 180 ° side opening (7, the 8) bottom surface and have an axis and center spool axis to coincide or parallel longitudinal direction perforate (9) on the cylinder, three perforates are formed in the threeway on the same plane; For improving sealing effect, in the upper and lower part, cylndrical surface of spool (2), respectively have 1-3 bar and central axis perpendicular sealing circular groove or step, when when pressure is very high, in groove and step, inserting seal ring (10,11); Spool end face center for connect handwheel () spool of (14) quickly (13), the spool top edge has the spacing prominent pin (17) of a restriction rotational angle or the circular arc wire casing that radian is 2 π/3 ± π/18.Valve gap (5) becomes disc, and its edge is equipped with several holes, so that be fixed on the valve body (1) with screw (12); On the valve gap inner face with valve body on have the circular arc shallow slot of one 2 π/3 ± π/18 radians or be provided with a spacing prominent pin (17) on two corresponding positions of side interface, constitute a limit angle apparatus by the projection on the spool and arc groove that covers or the arc groove on the spool with the projection that covers, so that the rotation angle of spool is limited in 120 ° ± 10 °.

For reducing the pressure loss, the internal diameter φ of two side direction interfaces on the aperture of two side direction perforates of this valve core (φ 1 ') and the valve body ₁Than being advisable with 0.7-1:1, the aperture of the vertical perforate of spool (φ 2 ') is that 1:1 is that best φ 1 is advisable with 1:1-2 with the ratio of φ 2 ' with the ratio of valve body longitudinal interface internal diameter (φ 2).

Wherein, 1-valve body (seat), 2-spool, the 3-valve gap, 4,5-valve body side direction interface, 6-valve body longitudinal interface, 7, the perforate of 8-spool side direction, the vertical perforate of 9-spool, the upper and lower seal ring of 10-, 11-middle part seal ring, the 12-retaining screw, the 13-spool quickly, 14-handwheel or handgrip, 15-tightening nut, 16-rotary spacing curve bath, the spacing prominent pin of 17-.

Embodiment and effect:

Example 1: I have made an interflow, shunting dual purpose valve by above-mentioned design proposal, and use as the hot water in bathroom, the valve at cold water interflow, and side pipe (4) is connect cold water, and side pipe (5) connects hot water, longitudinal tubule (L tubule) is done water outlet.Owing to go out cold water earlier when opening Kai, revolve again and then go out warm water, go out hot water at last again; When closing, because the effect of swiveling limitation mechanism needs the counterrotating spool, water temperature, is closed to temperature, to cold at last by heat, avoided fully causing scalding owing to opening by mistake valve, and also easy to operate, in the using process, the water temperature quite stable is easy to grasp.

Example 2: dual purpose valve is used as diverter valve, then vertical interface (pipe) as population, the turn spool can be in the stable shunting of two side interfaces (pipe) acquisition ratio of valve body, and its shunting ratio can be by regulating spool corner free hold.

Example 3: longitudinal interface (6) is connect compressor air-discharging or water-cooled condenser return pipe, interface (4,5) connects indoor and outdoor condenser or indoor reheater inlet and outdoor cooling tower inlet respectively, can realize the temperature adjustment in heat pump type drying (dehumidifying) the machine drying room, to satisfy the optimum drying temperature of different article.

Example 4: in central heating system, when radiator connects in the mode of connecting, the vertical interface (6) of this valve is tapped into water pipe, the horizontal interface of valve (4,5) is joined with the water intake and the water outlet of radiator respectively, by twisting the stopcock core, be the water yield that can regulate enters radiator, and do not influence total water flow of intake pipe; So can regulate room temperature well, and not influence its room temperature, avoid existing with valve interactional shortcoming in upper and lower layer room when temperature control.

This valve has excellent sealing performance, both can be used for liquid, also can be used for gas, and it can be used as hot and cold water interflow valve usefulness, also can use at the diverter valve on heating system, refrigeration system and the chemical engineering industry.It is of many uses, good reliability, and also easy to process, price is low.
