Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1: a kind of self-priming structure of washing agent of jetting machine, comprise the joint that is connected with the washing agent kettle, joint adopts siphon 2, siphon 2 is designed to a siphon pawl structure 12, conveniently be connected, be difficult for landing after packaging with the flexible pipe of washing agent kettle, and good airproof performance; The cavity 6 of pump cover 8 is as active chamber, siphon 2 is threaded in the upper end port of pump cover 8 cavitys 6 that high-pressure water flow flows through, and siphon 2 is connected with pump cover cavity 6, siphon 2 is built-in with one-way valve, and the seal ring 4 that is lined with between steel ball 3, steel ball 3 and siphon 2 inwall of one-way valve by the spring 5 that is fixed on siphon 2 lower end, spring 5 upper ends forms; The smooth sphere of steel ball 3 is as sealing surface, better tightness, and spring 5 is given 3 one precompressions of steel ball, guarantees that sealing is more reliable, and the O-ring seals that seal ring 4 adopts rubber materials to make is guaranteed the reliability that seals; Cavity 6 in the pump cover 8 is built-in with Venturi tube 7, Venturi tube 7 utilizes bernoulli principle to produce negative pressure and is arranged to horn strucutre, the converging transition 13 of horn strucutre has gap 9 and the cavity 6 in the pump cover 8, siphon 2 is connected, being lined with seal ring in the rear and front end of the cavity 6 in the pump cover and the converging transition 13 of Venturi tube 7 seals, seal ring adopts O-ring seals 1, and the negative cavity 11 and the high pressure water in the pump cover cavity 6 that produce are isolated; The water outlet port of pump cover 8 is outlet conduits 10, and outlet conduit 10 is connected directly or indirectly with the hydraulic giant that can regulate height, pressure retaining; At last, Venturi tube is in the cavity that is threaded in the pump cover.
Working principle: when machine is stopped using, because the spring force of spring 5 is less than washing agent pressure (washing agent pressure was 0 when the washing agent kettle was placed on siphon head below), so steel ball 3 is pushed to O-ring seals 4, push down O-ring seals 4, make and form sealing between steel ball 3 and the siphon 2, it is inner to cause washing agent to flow into by the gap between steel ball 3 and the siphon 2, and promptly washing agent is cut off automatically when machine is inactive;
When carrying out high-pressure wash, when hydraulic giant rifle head transfers to the high pressure retaining, the hole area A4 of hydraulic giant nozzle is smaller, total discharge is smaller, high pressure water is less in the flow velocity difference of each section, the pressure ratio of each section is bigger, hydraulic pressure can produce pressure on all directions, produce in the gap 9 of the converging transition 13 of Venturi tube 7 and to upward pressure, upward pressure for one on the surface of steel ball 3, add the elastic force of an original siphon spring 5, steel ball 3 surfaces upward pressure add upper spring 5 spring force greater than washing agent pressure, steel ball 3 is pushed to O-ring seals 4, push down O-ring seals 4 tightly, make to form sealing (as Fig. 2) between steel ball 3 and the siphon 2, cause washing agent to flow into inside by the gap between steel ball 3 and the siphon 2, promptly washing agent is cut off automatically when high-pressure wash;
When carrying out low pressure purge, hydraulic giant rifle head transfers to low pressure when retaining, this moment nozzle area A 4 bigger (relative with A1, A3 approaching).Because of the volume of the A1 that flows through in the unit time, A2, A3, A4 is identical, the sectional area of each section is in different size, so high pressure water can different (flow=area * flow velocity) through the flow velocity of each section, area and flow velocity are inversely proportional to.Therefore the flow velocity of V2 can be more faster than V1, V3, V4.According to bernoulli principle, can produce negative pressure at the A2 place, be directed downwards, negative pressure adds that the pressure of washing agent is far longer than the spring force of spring 5, and steel ball 3 is down pushed away, and makes steel ball 3 leave O-ring seals 4, cause producing gap (as Fig. 4) between steel ball 3 and the siphon 2, this moment, washing agent was inhaled into inside, formed the cleaning solution that mixes with current, sprayed from nozzle.Reach the purpose that washing agent sucks automatically.
If hydraulic giant rifle head is pushed to the high pressure retaining, will get back to the state of (Fig. 2), washing agent will be cut off.
