Description

A kind of compound mixed proportion valve
Technical field
The invention belongs to fire distinguisher technical field, more particularly to a kind of mixed proportion valve.
Background technology
At present, the proportioning valve used on domestic and international fire-fighting foams generator all be using directly with source water(Fire pump disappears The water that anti-system provides)It mixes, this results in foaming agent and cannot fully be mixed with fire water, greatly reduces the foaming of foaming agent Rate and its coefficient of foaming so as to which equal conditions area coverage reduces, increase fire extinguishing cost, waste substantial amounts of manpower and object Power.
Therefore, how to solve above-mentioned technical problem becomes the direction of field technology personnel effort.
The content of the invention
It is an object of the invention to provide a kind of compound mixed proportion valve, can be fully solved above-mentioned the deficiencies in the prior art it Place.
The purpose of the present invention is realized by following technical proposals:
A kind of compound mixed proportion valve, including shell, water inlet pipe, foaming agent delivery pipe, Venturi tube, blending bin and mixed liquor Delivery pipe, the blending bin are fixed in shell, and Venturi tube level crosses blending bin, the Venturi tube by two parts assemble and Into mating surface of the formation in blending bin, the shell are equipped with water inlet pipe installing port, foaming agent conveying between the two sections Pipe installing port and mixed liquor delivery pipe installing port, water inlet pipe is stretched by water inlet pipe installing port in shell to be connected with one end of Venturi tube It connects, the other end of Venturi tube is connected with one end of mixed liquor delivery pipe, and the other end of mixed liquor delivery pipe is conveyed by mixed liquor Pipe installing port stretches out shell, and foaming agent delivery pipe is stretched into shell by foaming agent delivery pipe installing port and is connected with blending bin, Water inlet pipe is installed between water inlet pipe and foaming agent delivery pipe.
Preferably, flow control valve is installed in the foaming agent delivery pipe.
Preferably, the caliber of the water inlet pipe is less than water inlet pipe caliber and foaming agent delivery pipe caliber.
Preferably, the water inlet pipe includes the first water inlet pipe and the second water inlet pipe, the first water inlet pipe is pacified by water inlet pipe Dress mouth is stretched into shell to be connected with the first tee pipe coupling, the second water inlet pipe be installed on the first tee pipe coupling and Venturi tube it Between;The foaming agent delivery pipe includes the first foaming agent delivery pipe and the second foaming agent delivery pipe, and the first foaming agent delivery pipe is led to It crosses foaming agent delivery pipe installing port and stretches into shell and be connected with the second tee pipe coupling, the second foaming agent delivery pipe is installed on second Between 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 present invention are:It is simple in structure, design is reasonable,
1. ensure that foaming agent and the water constant flow rate in the case of from external pressure fluctuations flow using venturi principle.
2. ensure that foam agent flux can be finely tuned arbitrarily on request using flow control valve, to reach the optimal of ratio on request Foam solution, so as to give full play to the optimal extinguishing effect of foaming agent.
3. foaming agent can be made to mix dilution repeatedly with fire water, so that foaming agent is uniformly sufficiently mixed with fire water It closes, ensures the coefficient of foaming of the foam solution of low expansion foam rifle, significantly improve to the upper limit value for being close to or up to standard requirement(20 Times blowing ratio).
Description of the drawings
Fig. 1 is the structure diagram of the present invention;
Fig. 2 is the partial enlarged view at A in Fig. 1.
Specific embodiment
With reference to specific embodiments and the drawings, the present invention is further illustrated.
As depicted in figs. 1 and 2, a kind of compound mixed proportion valve, including shell 1, water inlet pipe, foaming agent delivery pipe, Wen Pipe 2, blending bin 3, the first tee pipe coupling 4, the second tee pipe coupling 5, Linear flow control valve 6 and mixed liquor delivery pipe 7, institute Blending bin 3 to be stated to be fixed in shell 1,2 level of Venturi tube crosses blending bin 3, which is assembled by two parts, The mating surface 16 in blending bin 3 is formed between the two sections, and it is defeated that the shell 1 is equipped with water inlet pipe installing port 8, foaming agent Pipe installing port 9 and mixed liquor delivery pipe installing port 10 are sent, the water inlet pipe includes the first water inlet pipe 11 and the second water inlet pipe 12, the One water inlet pipe 11 is stretched into shell 1 by water inlet pipe installing port 8 and is connected with the first tee pipe coupling 4,12 one end of the second water inlet pipe It is connected with the first tee pipe coupling 4, the other end is connected with one end of Venturi tube 2, the other end and the mixed liquor delivery pipe of Venturi tube 2 7 one end connection, the other end of mixed liquor delivery pipe 7 stretch out shell 1 by mixed liquor delivery pipe installing port 10.The foaming agent Delivery pipe includes the first foaming agent delivery pipe 13 and the second foaming agent delivery pipe 14, and the first foaming agent delivery pipe 13 passes through foaming agent Delivery pipe installing port 9 is stretched into shell 1 and is connected with the second tee pipe coupling 5, and the second foaming agent delivery pipe 14 is installed on the two or three Between connection for bbreather pipe 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. Linear flow control valve 6 is installed in the first foaming agent delivery pipe 13.
The caliber of the water inlet pipe 15 is less than water inlet pipe caliber and foaming agent delivery pipe caliber, so as to improve water inlet pipe In 15 hydraulic pressure, enhance the mixed effect of fire water and foaming agent.
When in use, the fire water with pressure enters from water inlet pipe, and foaming agent enters from foaming agent delivery pipe.According to text Operation principle in mound, the fluid with certain pressure pass through the negative pressure of the generation certain pressure at back pressure of meeting after Venturi tube, mixing The pressure in liquid delivery pipe exit is consistently lower than the pressure of water inlet pipe and foaming agent delivery pipe, and foaming agent and fire-fighting current are always Direction flowing as shown in arrow(As shown in Figure 1, solid arrow represents fire-fighting current direction, dotted arrow represents foaming agent stream Dynamic direction).Fire water flows into foaming agent delivery pipe by water inlet pipe and is tentatively mixed with foaming agent, by what is tentatively mixed Foam solution carries out mixed diluting with fire water repeatedly along during foaming agent delivery pipe is flowed to blending bin, when into mixed After mould assembling, foam solution is entered in Venturi tube by the mating surface in the middle part of Venturi tube further with fire water mixed diluting, is finally led to Cross the output of mixed liquor delivery pipe.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention All any modification, equivalent and improvement made within refreshing and principle etc., should all be included in the protection scope of the present invention.
