Abstract
The utility model relates to a kind of pressure safety water sprager, the bottom of the piston of the pressing mechanism of water sprager is provided with unloader, when the pressure in kettle reaches unloader setting value, continue unloader meeting conducting when pressurizeing in kettle, use pressure in kettle cannot continue to increase, guarantee that in kettle, pressure is no more than the upper limit, ensure that the safety and reliability of water sprager, thus extend the service life of water sprager.
Description
Technical field
The utility model relates to a kind of water sprager, specifically a kind of pressure safety water sprager.
Background technology
Current vapour-pressure type water sprager generally comprises kettle body and pot lid, pot lid is provided with injection equipment and pressing mechanism, described pressing mechanism is an inflator, because existing vapour-pressure type water sprager does not have pressure relief means thereon, general experience of crossing when inflator pressurizes to kettle body of crossing judges, the explosion of kettle body can be caused during sometimes added hypertonia, thus affect the safety and reliability of water sprager.
Utility model content
The purpose of this utility model is providing a kind of pressure safety water sprager, the bottom of the piston of the pressing mechanism of water sprager is provided with unloader, when the pressure in kettle reaches unloader setting value, continue unloader meeting conducting when pressurizeing in kettle, use pressure in kettle cannot continue to increase, guarantee that in kettle, pressure is no more than the upper limit, ensure that the safety and reliability of water sprager, thus extend the service life of water sprager.
For achieving the above object by the following technical solutions:
A kind of pressure safety water sprager, comprise kettle body and pot lid, described pot lid is provided with pressing mechanism and injection equipment, injection equipment has a suction hose to extend in kettle body; It is characterized in that: described pressing mechanism comprises cylindrical shell and piston, the upper end of cylindrical shell is fixed on pot lid, lower end extends in kettle body, piston is along for accommodation in cylindrical shell, and top land connects pressurized handgrip, and the connecting rod of pressurized handgrip is through pot lid, handle cap is screwed in the top of connecting rod and is positioned at the top of pot lid, the bottom of described cylindrical shell is provided with breather check valve, and the bottom discharge channel of described piston, is provided with unloader in discharge channel.
Described discharge channel is in " 7 " font, and wherein air inlet is provided with the bottom of piston, and gas outlet arranges the sidepiece of piston; Described unloader comprises spring and steel ball, longitudinal section of steel ball and spring retention " 7 " font discharge channel, and the external diameter of steel ball is greater than the bore of air inlet, and air inlet seals by steel ball under the action of the spring.
The utility model is provided with unloader in piston base, when the air pressure in kettle reaches the settings of unloader, continue again to pressurize in kettle, the steel ball of unloader backs down and makes discharge channel conducting by the air pressure now in kettle, thus play the effect of exhaust step-down, and when kettle internal gas pressure drop to be less than unloader settings time, discharge channel again can by self-closed; Play the effect protected and protect kettle body, ensure that the safety and reliability of water sprager, and extend the service life of water sprager.
Accompanying drawing explanation
Fig. 1 is external structure schematic diagram of the present utility model;
Fig. 2 is the structural representation of the utility model pressing mechanism and injection equipment;
Fig. 3 is the internal structure schematic diagram of the utility model pressing mechanism.
Detailed description of the invention
As Figure 1-3, a kind of pressure safety water sprager, comprises kettle body 1 and pot lid 2, and described pot lid 2 is provided with pressing mechanism 3 and injection equipment 5, and injection equipment 5 has a suction hose 51 to extend in kettle body 1; Described pressing mechanism 3 comprises cylindrical shell 31 and piston 32, the upper end of cylindrical shell 31 is fixed on pot lid 2, lower end extends in kettle body 1, piston 32 is along for accommodation in cylindrical shell 31, and piston 32 top connects pressurized handgrip 33, and the connecting rod 34 of pressurized handgrip 33 is through pot lid 2, handle cap 35 is screwed in the top of connecting rod 34 and is positioned at the top of pot lid 2, the bottom of described cylindrical shell 31 is provided with breather check valve 36, and the bottom discharge channel 37 of described piston 32, is provided with unloader in discharge channel 37; Described discharge channel is in " 7 " font, and wherein air inlet is provided with the bottom of piston, and gas outlet arranges the sidepiece of piston; Described unloader comprises spring 38 and steel ball 39, longitudinal section of steel ball 39 and spring 38 accommodating " 7 " font discharge channel 37, and the external diameter of steel ball 39 is greater than the bore of air inlet, and air inlet seals by steel ball 39 under spring 38 acts on.
The maximum feature of the utility model is provided with breather check valve in the bottom of cylindrical shell, and piston base is provided with unloader, when kettle internal gas pressure is less than unloader limit value, pressing mechanism can normally pressurize to kettle body, and after kettle internal gas pressure reaches unloader limit value, continue pressurization, the steel ball of unloader backs down by hyperbar in kettle automatically, make discharge channel conducting, play the effect of exhaust step-down, ensure that the air pressure in kettle is no more than the limit value of unloader, ensure that the safety and reliability of water sprager, thus extend the service life of water sprager.
