Abstract
The built-in air chamber safety valve of sprayer, comprise seat under the air chamber be arranged in sprayer explosive barrel, under air chamber, seat install air chamber, under described air chamber seat a sidewall on set out the mouth of a river, connecting tube is shaped with outside water outlet, the outer sheathed bonnet of connecting tube, described bonnet sets out water hole, and osculum is communicated with air chamber through water outlet, spring and sealed valve core are set in described connecting tube, one crown of spring is on bonnet, and sealed valve core is withstood in the other end of spring, and sealed valve core matches with water outlet.When the pressure in air chamber reaches the working pressure of restriction; exert pressure to air chamber if continue, the pressure in air chamber will oppress sealed valve core, makes sealed valve core overcome the pressure of spring; be separated with water outlet; liquid in air chamber flows back in explosive barrel from osculum through water outlet, and air chamber is off-load immediately, and pressure does not rise; reach the object of protection air chamber; air chamber long service life, reduces maintenance, changes number of times, reduce maintenance cost.
Description
Technical field
The utility model relates to sprayer, particularly relates to the built-in air chamber safety valve of a kind of sprayer, belongs to sprayer component.
Background technique
The kind of sprayer has a lot, and for knapsack sprayer, its atomisation pressure is generally 2-4bar.If atomisation pressure is too low, droplet is thick, and liquid easily runs off, prevention effect difference and befouling environment, and atomisation pressure is too high, easily causes droplet to drift about, cause poisoning to closing on crop, and too high hydraulic pressure easily causes air chamber, sebific duct, nozzle to damage ring in advance, affects its working life.Therefore, prior art in the liquid pump parts of sprayer owing to not arranging safety valve, but when reality uses, the pressure of air chamber carrying often can reach 6 ~ 8bar, and the bursting pressure of standard-required air chamber is only 12bar, therefore, above-mentioned working pressure is close to the pressure maximum that air chamber can bear, seriously have impact on product working life, there is hidden danger.
Summary of the invention
The purpose of this utility model is the shortcoming in order to overcome prior art, and provide a kind of structure simple, easy processing, bearing capacity is large, the built-in air chamber safety valve of sprayer of long service life.
The technological scheme of the built-in air chamber safety valve of the utility model sprayer is: comprise seat under the air chamber be arranged in sprayer explosive barrel, under air chamber, seat installs air chamber, the sidewall that it is characterized in that seat under described air chamber sets out the mouth of a river, connecting tube is shaped with outside water outlet, the outer sheathed bonnet of connecting tube, described bonnet sets out water hole, osculum is communicated with air chamber through water outlet, spring and sealed valve core are set in described connecting tube, one crown of spring is on bonnet, sealed valve core is withstood in the other end of spring, and sealed valve core matches with water outlet.
The built-in air chamber safety valve of sprayer of the present utility model, main feature be seat under air chamber a sidewall on set out the mouth of a river, connecting tube is shaped with outside water outlet, at the outer sheathed bonnet of connecting tube, bonnet sets out water hole, spring and sealed valve core are set in connecting tube, one crown of spring is on bonnet, sealed valve core is withstood in the other end of spring, sealed valve core matches with water outlet, when the pressure in air chamber reaches the working pressure of restriction, if continue, air chamber is exerted pressure, pressure in air chamber will oppress sealed valve core, sealed valve core is made to overcome the pressure of spring, be separated with water outlet, liquid in air chamber flows back in explosive barrel through water outlet from osculum, air chamber is off-load immediately, pressure no longer rises, reach the object of protection air chamber, air chamber long service life, reduce maintenance, change number of times, reduce maintenance cost.
The built-in air chamber safety valve of sprayer of the present utility model, under described connecting tube and air chamber, seat is plastic materials integrated injection molding, easy processing, and cost is economized.Described bonnet and connecting tube are through to be threaded or buckle is connected, and be threaded conveniently, and can turn bonnet, regulate the pressure to spring, it is firm that buckle connects.Described sealed valve core can be the sealed valve core of the various shapes such as ball sealer, and ball sealer sealing effect is better.
Accompanying drawing explanation
Fig. 1 is the utility model sprayer built-in air chamber safety valve arrangement schematic diagram.
Embodiment
The utility model relates to the built-in air chamber safety valve of a kind of sprayer, as shown in Figure 1, comprise seat 1 under the air chamber be arranged in sprayer explosive barrel, seat is installed air chamber 2 under air chamber, under described air chamber seat 1 a sidewall on set out the mouth of a river 3, connecting tube 4 is shaped with outside water outlet 3, the outer sheathed bonnet 5 of connecting tube 4, described bonnet 5 sets out water hole 6, osculum 6 is communicated with air chamber 2 through water outlet 3, spring 7 and sealed valve core 8 are set in described connecting tube 4, one crown of spring 7 is on bonnet 5, sealed valve core 8 is withstood in the other end of spring 7, sealed valve core 8 matches with water outlet 3.The main feature of this programme be seat 1 under air chamber a sidewall on set out the mouth of a river 3, connecting tube 4 is shaped with outside water outlet 3, at the outer sheathed bonnet 5 of connecting tube 4, bonnet 5 sets out water hole 6, spring 7 and sealed valve core 8 are set in connecting tube 4, one crown of spring 7 is on bonnet 5, sealed valve core 8 is withstood in the other end of spring 7, sealed valve core 8 matches with water outlet 3, when the pressure in air chamber 2 reaches the working pressure of restriction, if continue, air chamber is exerted pressure, pressure in air chamber 2 will oppress sealed valve core 8, sealed valve core 8 is made to overcome the pressure of spring 7, be separated with water outlet 3, liquid in air chamber 2 flows back in explosive barrel through water outlet 3 from osculum 6, air chamber is off-load immediately, pressure no longer rises, reach the object of protection air chamber, air chamber long service life, reduce maintenance, change number of times, reduce maintenance cost.Described connecting tube 4 is plastic materials integrated injection molding with seat 1 under air chamber, easy processing, and cost is economized.Described bonnet 5 and connecting tube 4 are connected through screw thread 9 or buckle connects, and are threaded conveniently, and can turn bonnet, regulate the pressure to spring, and it is firm that buckle connects.Described sealed valve core 8 can be the sealed valve core of the various shapes such as ball sealer, and ball sealer sealing effect is better.
