Description

Proportional flow controlling valve

The utility model relates to the configuration valve that is specially adapted for the fluid-mixing flow line, specifically belongs to a kind of fluid-mixing excess-flow valve.

In daily life, people often need mix two kinds of fluid at differing temperatures and use after transferring the fluid-mixing of converting into preference temperature, as when the shower, need the hot water or cold water is transferred the water that convert into preference temperature.The device that present this accent condition is adopted is that the pipeline opening the hot water or cold water respectively is provided with a valve, be connected with a threeway between two valves, in use, regulate two valves respectively, till suiting to the water temperature that flows out to fluid-mixing to control hot water or cold water's flow respectively.The deficiency that this device exists is that used component are many, and in use, because the hot water or cold water is parallel convection current, so, when a side water flow is big, can influence the water flow of opposite side, therefore transfer usually to occur sometimes hot and sometimes cold phenomenon when converting, so transfer time-consuming taking a lot of trouble when converting, also caused the waste of water resources simultaneously.

The purpose of this utility model just provides a kind of operated proportional flow control valve that is two kinds of different fluid flows of may command with a valve only.

The purpose of this utility model is that reality is existing like this: designed valve body is the threeway shape, and valve inner is the horizontal cylinder hole, and cock is inserted in this cylindrical hole, and by the end cap sealing-in, has the corresponding Y shape communication channel that communicates with valve body three ports in the cock.

When assembling with pipeline, two mouths in valve body three ports join with cool and hot water pipe respectively, another opening is the water outlet of fluid-mixing, when cock turns an angle, the water outlet of fluid-mixing is corresponding on passage of the Y shape communication channel in the cock and the valve body, and the two other passage is conducted with hot water or cold water's import respectively, after the two passes of hot water or cold water's stream by Y shape passage converges, form the fluid-mixing of hot and cold water, from the water outlet outflow of valve body.When rotating tap handle, the Y shape communication channel in the cock rotates thereupon, so when the area of a side canal and cold water outlet connection in the Y shape passage increased, the area that opposite side passage and hot water mouth connect can reduce, forms when cool water quantity increases, and the hot water amount reduces.Otherwise when the hot water amount increased, cool water quantity reduced, and had reached the purpose of regulated at will water temperature.Owing to be to adopt directly two kinds of liquid of control of a valve, make hot and cold water in valve, directly mix alternating temperature and then flow simultaneously, therefore shortened and transferred the time of converting water temperature, saved water resources.

Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.

Fig. 1, Fig. 2 are the structural representations of two kinds of implementations of the present utility model.

Fig. 3 is the outward appearance plan view of Fig. 1.

As Fig. 1, shown in Figure 3, the designed valve body 1 of the utility model is provided with three ports, and three ports are respectively hot water inlet 1a, cooling water inlet 1b, mixed water exports 1c, and valve body 1 inside is the horizontal cylinder hole, and cock 2 is inserted in this cylindrical hole, by end cap 3 sealing-ins.The sealing surface of designed cock 2 is provided with three holes, three Kong Jun lead to a bit Y-shaped communication channel in axle center, this Y shape communication channel can be conducted with three ports of valve body 1, make hot and cold current converge the water outlet 1c outflow of back from valve body 1 top, be the water-outlet quantity that guarantees that weighing apparatus is fixed, establish the corresponding connection of outlet 1c on bigger major path 2c of an internal diameter and valve body 1 top in the Y of cock shape communication channel, two water intake 1a, the 1b of two other small channel 2a, 2b and valve body 1 are connected.Like this, both can guarantee cock when rotating certain limit, the connection area at the hot and cold mouth of a river has to increase to have and subtracts, and the connection area of water outlet is constant, forms the fixed water-outlet quantity of weighing apparatus.

For the ease of making, can the both sides on the valve body 1 water inlet 1a, 1b is parallel relatively, Y shape passage in the corresponding cock is arranged to two angles between small channel 2a, the 2b greater than the angle between major path 2c and two small channels (2a, 2b), with guarantee in two small channel 2a, 2b and valve body 1 hot water inlet 1a, when cooling water inlet 1b is connected, it is corresponding that major path 2c just is being better than the water outlet 1c of valve casing 1, when cock 2 turned an angle, the sealing surface of cock 2 was good down again with three port Close Alls on the valve body 1.Operated proportional flow control valve according to this designing institute preparation, comparatively easy during making, but in use, be in two states only, a kind of is that all passages in the Y shape communication channel in the cock 2 and three ports on the valve body 1 are conducted, the sealing surface that another kind of state is cock 2 makes three ports on the valve body 1 all be in closed state, therefore its application area has certain restriction, as disposing on the pouring chamber that only is adapted to the thermal water source, the flow line road between wash water, do not dispose and be suitable on the flow line road of solar water heater.For addressing this problem, the utility model also can be arranged to operated proportional flow control valve as shown in Figure 2.The internal orifice that is about to three ports of valve body 1 is divided equally section circle of cylindrical hole in the valve body 1, be valve body both sides water intake 1a, the shaft axis angle that the internal orifice of 1b is opened cylindrical hole in pointing to valve body 1 is 120 °, Y shape passage in the corresponding cock is arranged to two small channel 2a, angle between the 2b is less than major path 2c and small channel 2a, angle between the 2b, this design is except that guaranteeing that valve is in use except that the above-mentioned two kinds of user modes of tool, also can have when cock 2 turns an angle, be conducted with hot water inlet 1a and cooling water inlet 1b in the valve body 1, and the water outlet 1c of valve body 1 is in closed condition, like this, when this valve is assemblied in the flow line road of solar water heater, after the hot water in the water storage tank of solar water heater is used up, promptly rotatable cock is closed the water outlet of valve casing, cold water charges in the water storage tank by the hot water mouth, reaches the purpose of water.Operated proportional flow control valve according to this designing institute preparation because technological requirement is higher, so cost is relatively also more higher, but can enlarge application area, can be assemblied in all runner pipelines that need the hot and cold water mixing.

The utility model also can be designed to all have the cylinder bodily form of identical tapering with cylindrical hole in the valve body 1 and corresponding cock 2, seals tight cock 2 so that the trace wearing and tearing to be arranged in cock 2, still can guarantee its sealability.

Operated proportional flow control valve according to above designing institute provides only need rotate the flow that valve plug can be controlled the hot water or cold water simultaneously gently, reaches the purpose of regulating water temperature, therefore uses very simple, convenient. Of the present utility modelly be also advantageous in that using a valve is that two valves and the threeway in the device converted in alternative existing accent, thereby reduced and transferred the part consumption of converting in the device, thereby saved raw material, reduced cost, also reduced the workload when installing simultaneously. In addition, because the utility model is reduced to one with the control valve of different fluid, the laying in the flow line road of washroom is become succinctly, neatly.
