Abstract
The utility model relates to a spray valve, which comprises a valve lever 1, wherein the valve lever is provided with a step-like inner chamber 2 and the closer the step-like inner chamber away from the outlet is, the smaller the inner diameter of the step-like inner chamber is; an air inlet pipe 8 is arranged on a side of the valve lever, and the high-pressure gas from the air inlet pipe 8 directly enters into the step-like inner chamber 2; a valve core 3 is arranged in the valve lever and the outer diameter of the valve core 3 is smaller than the inner diameter of the step-like inner chamber 2; the valve core 3 is provided with an inner chamber 4 with the outlet smaller than the inlet; an air inlet port 5 is arranged in the near-end part of the valve core 3; a mixing chamber 6 is arranged at the top of the valve core and the inner diameter of the mixing chamber is larger than the inner diameter of the valve core outlet; a spray nozzle 7 is arranged at the top of the mixing chamber 6 and the inner diameter of the spray nozzle 7 is larger than the inner diameter of the mixing chamber 6. The spray valve of the utility model is easy in manufacture, good at processing, simple in structure and convenient in maintaining and replacing. Due to the higher working pressure and flow, the utility model can improve the working efficiency.
Description
Technical field
The utility model relates to the whitewashing valve, particularly is used for the whitewashing valve that face the wall and meditate in the New Built Mine tunnel, Expressway Embankment is reinforced, face the wall and meditate and reinforce in the tunnel.
Background technology
Be used at present that mine laneway is faced the wall and meditated, Expressway Embankment is reinforced, face the wall and meditate in the tunnel reinforce with the sprayer unit flow little, inefficiency, atomizing effect is poor, complex structure stop up easily, and the connecting interface versatility is poor, is connected loaded down with trivial details with mining device.
Goal of the invention
In order to solve the problem of above-mentioned existence, designer of the present utility model has designed a kind of novel whitewashing valve.This valve is not only simple in structure, flow is big but also atomizing effect is good.
Whitewashing valve of the present utility model comprises: a valve rod 1, it is characterized in that described valve rod is provided with step-like inner chamber 2, and this step-like inner chamber is more little the closer to its internal diameter of Way out; Side at described valve rod is provided with air inlet pipe 8, gases at high pressure from this air inlet pipe 8 directly enter inner chamber step-like in the above-mentioned valve rod 2, in described valve rod, be provided with a spool 3, the external diameter of this spool 3 is less than the internal diameter of the step-like inner chamber 2 of valve rod, this spool 3 is provided with the inner chamber 4 of its outlet less than inlet, is provided with an air admission hole 5 in the position of these spool 3 close ends; Be provided with hybrid chamber 6 on described spool top, the internal diameter of hybrid chamber is greater than the internal diameter of spool outlet; Be provided with mouth spray 7 on the top of hybrid chamber 6, the internal diameter of mouth spray 7 is less than the internal diameter of hybrid chamber 6.
The another of whitewashing valve of the present utility model be characterised in that, the internal diameter of described hybrid chamber is 2～4 times of internal diameter of mouth spray 7.
Whitewashing valve processing of the present utility model is easy, and good manufacturability is simple in structure, is convenient to maintenance, changes.Because therefore whitewashing valve operating pressure of the present utility model and flow is higher, atomizing effect is good, has improved operating efficiency greatly.
Description of drawings
Fig. 1 is the section of structure of whitewashing valve of the present utility model.
The specific embodiment
Followingly be elaborated with reference to the specific embodiment of accompanying drawing to whitewashing valve of the present utility model.
Fig. 1 is the specific embodiment of whitewashing valve of the present utility model.1 is a valve rod, and this valve rod 1 is provided with step-like inner chamber 2, and this step-like inner chamber 2 is more little the closer to its internal diameter of Way out; Side at described valve rod 2 is provided with air inlet pipe 8, gases at high pressure from this air inlet pipe 8 directly enter inner chamber step-like in the above-mentioned valve rod 2, in described valve rod, be provided with a spool 3, the external diameter of this spool 3 is less than the internal diameter of the step-like inner chamber 2 of valve rod, this spool 3 is provided with the inner chamber 4 of its outlet less than inlet, is provided with an air admission hole 5 in the position of these spool 3 close ends; Be provided with hybrid chamber 6 on the top of described spool 3, the internal diameter of hybrid chamber is greater than the internal diameter of spool outlet; Be provided with mouth spray 7 on the top of hybrid chamber 6, the internal diameter of mouth spray 7 is less than the internal diameter of hybrid chamber 6.
Whitewashing valve of the present utility model, the internal diameter of its hybrid chamber 6 are 2～4 times of internal diameter of mouth spray 7.
Below, the course of work of the whitewashing valve of this utility model is elaborated.This whitewashing valve is a tubular structure, is connected with the water under high pressure dredge pump.Wherein, the port away from an end of mouth spray 7 on the valve rod connects the water under high pressure dredge pump, and air inlet pipe 8 is an air inlet away from the port of valve rod one end, and mouth spray 7 is vaporific cement jets.Come for water under high pressure mud and push spool open to flow fast by the port away from an end of mouth spray 7 on the water under high pressure dredge pump cut-in valve bar to valve pocket, simultaneously, because the effect of the high pressure gas that enters from the air inlet of air inlet pipe 8, cement mortar is sprayed to mouth spray 7, because whitewashing valve of the present utility model is established hybrid chamber 6, gases at high pressure and cement mortar fully mix in hybrid chamber, form atomizing, reach the effect of even spraying.
Whitewashing valve processing of the present utility model is easy, and good manufacturability is simple in structure, is convenient to maintenance, changes.Because therefore whitewashing valve operating pressure of the present utility model and flow is higher, atomizing effect is good, has improved operating efficiency greatly.
