Abstract
The utility model provides a mass-flow manual-operation foam proportion mixer and belongs to the technical field of firefighting apparatus manufacturing and application. The mass-flow manual-operation foam proportion mixer mainly solves the technical problems that installation and maintenance are complex and foaming effect of foams is dissatisfactory due to the fact that in the prior art,a main valve and a ventuti tube are integrated. The mixer separates the ventuti tube from the foam control main valve and enables the ventuti tube to have better foam leading effect. The main valve is directly arranged on a pedal, and the connecting portion is flexibly connected through a groove-type pipe clamp. The working principle of the mass-flow manual-operation foam proportion mixer is that pressure water flowing out of a water pump flows into an inlet of the ventuti tube, vacuum is formed through spray of water flow in the ventuti tube, and then pressure difference is formed between a pipeline of the inlet of the foams and the ventuti tube, and therefore an expected foam mixing ratio can be achieved by operating the main valve to control volume of foam flow. Foam liquid flows out a foam outlet of the main valve and flows into the foam inlet of the ventuti tube, and then flows into a water inlet pipeline through the ventuti tube after being mixed with water, and finally the foam mixed liquor is formed. The mass-flow manual-operation foam proportion mixer has the advantages of being reliable in structure, flexible and convenient to install, adjustable in foam mixing ratio, and high in flow control accuracy.
Description
Technical field
The utility model relates to a kind of manual foam proportioner, particularly a kind of high flow manual foam proportioner.This blender is applicable to big flow water pump, belongs to fire-fighting equipment manufacturing and applied technical field.
Background technology
In actual fire-fighting fire extinguishing operation process, need use the water pump of big flow to carry out the fire-fighting fire extinguishing operation through regular meeting, to reach better fire extinguishing effect.The foam proportioner that need match simultaneously satisfies the frostproof froth n effect of fire extinguishing needs.Solve this type of problem, just need the foam proportioner of big flow.At present, domestic have only PH64 and two kinds of manual foam proportioners of PH32.The main valve and the Venturi tube of above-mentioned blender are structure as a whole, and its structure is single, install and safeguard miscellaneous.The foam flow that can pass through more can not satisfy the needs of big flow water pump, can not reach required frostproof froth n effect.
Summary of the invention
The purpose of the utility model is the deficiency to above-mentioned prior art, and a kind of novel high flow manual foam proportioner is provided.This blender has mainly solved the prior art main valve and Venturi tube is structure as a whole, and installs, safeguards the dissatisfactory technical problem of foaming effect of complicacy and foam.
For realizing above-mentioned purpose; The utility model adopts following technical proposals: the high flow manual foam proportioner; Venturi tube and foam control main valve are separated; Venturi tube is had better draw foam effect, main valve then is directly installed on the panel place, and the junction connects through the plough groove type pipe clamp flexibly.Its concrete structure is: the high flow manual foam proportioner comprises control main valve (1) and Venturi tube (3).Main valve (1) is made up of valve body (13) and spool (14) and is installed on the pump chamber control panel (15).Be fixed with label (21) on the valve body (13), handle (22) is installed on the spool (14).The foam inlet C (19) of above-mentioned main valve (1) is connected with foam inlet A (7) through pipeline; Opposite side foam outlet (20) communicates with the foam inlet B (18) of Venturi tube (3) through pipeline.The inlet (16) of Venturi tube (3) is connected with the delivery port (12) of water pump (4) through pipeline; The outlet (17) of Venturi tube (3) is connected with water inlet (11) through pipeline.Pipeline between main valve (1) and the foam inlet A (7) is provided with pneumatic control ball valve B (6); Pipeline is provided with pneumatic control ball valve A (10) between the inlet (16) of pump outlet (12) and Venturi tube (3), and the pipeline between pump outlet (12) and the main valve (1) is provided with pneumatic control ball valve C (5).Pipeline between the inlet (16) of above-mentioned water pump (4) delivery port (12) and Venturi tube (3) adopts groove card (2) to be connected; Manually control ball valve B (8) is connected on the foam inlet C (19) and the pipeline between the foam inlet A (7) of main valve (1), manually controls ball valve A (9) and is connected between the inlet (16) and pump outlet (12) of Venturi tube (3) through pipeline.
Operation principle: the press water that is flowed out by pump outlet (12) gets into the inlet (16) of Venturi tube (3); Spray the formation vacuum through Venturi tube (3) water flow inside; And the pipeline between the foam inlet A (7) forms pressure reduction; Make foam solution pass through the foam inlet C (19) that foam inlet A (7) flows into main valve (1), make spool (14) rotate the size of controlling the foam flow, reach the foams mix ratio of expection through operating grip (22).The foam outlet (20) that foam solution flows out main valve (1) gets into the foam inlet B (18) of Venturi tube (3), mixes the back with water and flows in water inlet (11) pipeline through Venturi tube (3) outlet (17), forms foam mixing liquid.
The characteristics of the utility model are: (1) Venturi tube and the partial installation of control main valve have Venturi tube and better draw foam effect; (2) foams mix compares the scalable mixing ratio from 0～10%; (3) has flow-control more accurately; (4) reliable in structure, convenient and flexible installation.
