Description
Technical field
The utility model belongs to fire distinguisher technical field, particularly relates to a kind of mixed proportion valve.
Background technology
At present, the proportioning valve that domestic and international fire-fighting foams generator uses is all that employing is direct and source water (water that fire pump or fire-fighting system provide) is mixed, this just causes foaming agent and fire water can not be fully mixed, greatly reduce frothing percentage and the coefficient of foaming thereof of blowing agent, thus equal conditions area coverage reduces, increase fire extinguishing cost, waste a large amount of man power and materials.
Therefore, the direction becoming these those skilled in the art and make great efforts how is solved the problems of the technologies described above.
Utility model content
The purpose of this utility model is just to provide a kind of compound mixed proportion valve, can solve above-mentioned the deficiencies in the prior art part completely.
The purpose of this utility model is realized by following technical proposals:
A kind of compound mixed proportion valve, comprise shell, water inlet pipe, foaming agent carrier pipe, Venturi tube, blending bin and mixed liquor carrier pipe, described blending bin is fixed in shell, Venturi tube level crosses blending bin, this Venturi tube is assembled by two parts, form the mating surface be in blending bin between the two sections, described shell is provided with water inlet pipe installing port, foaming agent carrier pipe installing port and mixed liquor carrier pipe installing port, water inlet pipe is stretched in shell by water inlet pipe installing port and is connected with one end of Venturi tube, the other end of Venturi tube is connected with one end of mixed liquor carrier pipe, the other end of mixed liquor carrier pipe stretches out shell by mixed liquor carrier pipe installing port, foaming agent carrier pipe is stretched in shell by foaming agent carrier pipe installing port and is connected with blending bin, between water inlet pipe and foaming agent carrier pipe, water inlet pipe is installed.
As preferably, described foaming agent carrier pipe is provided with flow control valve.
As preferably, the caliber of described water inlet pipe is less than water inlet pipe caliber and foaming agent carrier pipe caliber.
As preferably, described water inlet pipe comprises the first water inlet pipe and the second water inlet pipe, and the first water inlet pipe is stretched in shell by water inlet pipe installing port and is connected with the first tee pipe coupling, and the second water inlet pipe is installed between the first tee pipe coupling and Venturi tube; Described foaming agent carrier pipe comprises the first foaming agent carrier pipe and the second foaming agent carrier pipe, first foaming agent carrier pipe is stretched in shell by foaming agent carrier pipe installing port and is connected with the second tee pipe coupling, and the second foaming agent carrier pipe is installed between the second tee pipe coupling and blending bin; Water inlet pipe is installed between the first tee pipe coupling and the second tee pipe coupling.
Compared with prior art, the beneficial effects of the utility model are: structure is simple, reasonable in design,
1. foaming agent and water is not when flowing by constant flow rate when external pressure fluctuations to utilize venturi principle to ensure.
2. adopt flow control valve to ensure that foaming agent flow can be finely tuned arbitrarily on request, to reach the best foam solution of ratio on request, thus give full play to the best extinguishing effect of foaming agent.
3. can make that foaming agent and fire water are repeatedly mixed dilute, thus foaming agent and fire water are evenly mixed fully, the coefficient of foaming of the foam solution of guarantee low expansion foam rifle, significantly improve to close or reach the higher limit (20 times of blowing ratios) of standard-required.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing at A place in Fig. 1.
Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the utility model is further described.
As depicted in figs. 1 and 2, a kind of compound mixed proportion valve, comprise shell 1, water inlet pipe, foaming agent carrier pipe, Venturi tube 2, blending bin 3, first tee pipe coupling 4, second tee pipe coupling 5, Linear flow control valve 6 and mixed liquor carrier pipe 7, described blending bin 3 is fixed in shell 1, Venturi tube 2 level crosses blending bin 3, this Venturi tube 2 is assembled by two parts, form the mating surface 16 be in blending bin 3 between the two sections, described shell 1 is provided with water inlet pipe installing port 8, foaming agent carrier pipe installing port 9 and mixed liquor carrier pipe installing port 10, described water inlet pipe comprises the first water inlet pipe 11 and the second water inlet pipe 12, first water inlet pipe 11 is stretched in shell 1 by water inlet pipe installing port 8 and is connected with the first tee pipe coupling 4, second water inlet pipe 12 one end is connected with the first tee pipe coupling 4, the other end is connected with one end of Venturi tube 2, the other end of Venturi tube 2 is connected with one end of mixed liquor carrier pipe 7, the other end of mixed liquor carrier pipe 7 stretches out shell 1 by mixed liquor carrier pipe installing port 10.Described foaming agent carrier pipe comprises the first foaming agent carrier pipe 13 and the second foaming agent carrier pipe 14, first foaming agent carrier pipe 13 is stretched in shell 1 by foaming agent carrier pipe installing port 9 and is connected with the second tee pipe coupling 5, and the second foaming agent carrier pipe 14 is installed between the second tee pipe coupling 5 and blending bin 3.Water inlet pipe 15 is installed between the first tee pipe coupling 4 and the second tee pipe coupling 5.First foaming agent carrier pipe 13 installs Linear flow control valve 6.
The caliber of described water inlet pipe 15 is less than water inlet pipe caliber and foaming agent carrier pipe caliber, thus improves the hydraulic pressure of in water inlet pipe 15, strengthens the mixed effect of fire water and foaming agent.
In use, the fire water with pressure enters from water inlet pipe, and foaming agent enters from foaming agent carrier pipe.According to venturi operation principle, there is the fluid of certain pressure by can produce the negative pressure of certain pressure after Venturi tube at back pressure place, the pressure in mixed liquor carrier pipe exit is all the time lower than the pressure of water inlet pipe and foaming agent carrier pipe, foaming agent and fire-fighting current press the direction flowing shown in arrow (as shown in Figure 1 all the time, solid arrow represents fire-fighting current direction, and dotted arrow represents foaming agent flow direction).Fire water flows into foaming agent carrier pipe by water inlet pipe and tentatively mixes with foaming agent, in the process that the foam solution of preliminary mixing flows to blending bin along foaming agent carrier pipe, repeatedly carry out mixed diluting with fire water, after entering blending bin, foam solution by the mating surface in the middle part of Venturi tube to enter in Venturi tube further with fire water mixed diluting, export finally by mixed liquor carrier pipe.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
