Abstract
The utility model provides a gas nozzle with adjustable flow, comprising a nozzle body provided with an air inlet and an air outlet, a needle valve is telescopically sealedly sleeved in nozzle body, the front end of the needle valve is provided with a conical tapering surface capable of completely blocking the air outlet, the needle valve can move along the inner cavity of the nozzle body and can be positioned at a position corresponding to any openness degree in the range of from full opening to full closing of the air outlet. The inner wall of the nozzle body is provided with a guiding conical surface tapering toward the air outlet. The beneficial effects of the gas nozzle in the utility model are in that: via adjustment of the movable needle valve, a hole diameter of the nozzle is adjusted, thereby solving requirement for replacing the nozzle in replacement, saving cost for users, and reducing replacement time of natural gas; when the gas nozzle in the utility model is used to adjust the nozzle device, the needle valve is only needed to be rotated, providing convenience, fastness, and safety, and preventing worries.
Description
Technical field
The utility model relates to a kind of gas nozzle, is specifically related to the adjustable gas nozzle of a kind of flow.
Background technology
Along with the propelling of Chinese market for natural gas West-East National Gas Transmission Project, increasing family uses has gone up natural gas, and the kitchen range user of the original cities and towns pipeline gas (artificial coal gas) that uses will face the engineering of displacement, and time-consuming, effort also will increase the displacement expense.Usually in the gas replacement engineering, need to change original giant aperture into the small nozzle aperture, in displacement, need the more kitchen range parts of mounting or dismounting, operation is loaded down with trivial details, and cost is too high.
Summary of the invention
To the problems referred to above that prior art exists, the utility model provides a kind of flow adjustable gas nozzle.
The technical scheme that realizes the utility model purpose is:
The gas nozzle that a kind of flow is adjustable; Comprise nozzle body with air inlet and gas outlet; The airtight needle-valve that is set with of telescopically in the said nozzle body; The needle-valve front end has the taper contraction front of shutoff gas outlet fully, and needle-valve can move and can locate in the position corresponding with any aperture of gas outlet full open to the totally-enclosed scope along the nozzle body inner chamber.
Further, said nozzle body inwall has the guiding conical surface that shrinks to the gas outlet.
Further, another relative sidewall of said nozzle body and gas outlet has screwed hole, and said needle-valve has and the airtight external screw thread that cooperates of nozzle body screwed hole.
Further, said needle-valve rear end has the slot that can cooperate with screwdriver.
Further, said nozzle body has tubular cavity, and gas outlet and screwed hole lay respectively at the two ends of tubular cavity, and needle-valve can move in tubular cavity, and said air inlet is positioned at the side of tubular cavity.
Further, the bus and the axis angle of end toper contraction front is 10 ° ~ 20 ° before the said needle-valve.
Further, the bus of said nozzle body inwall guiding conical surface and axis angle are 45 ° ~ 70 °.
The beneficial effect of the utility model mainly shows: through regulating movably needle-valve, regulate the aperture of nozzle, thereby solved the requirement of changing nozzle in the displacement again, practiced thrift cost to the user, also reduced the time of gas replacement simultaneously; Adopt the utility model to regulate spray nozzle device, as long as rotate needle-valve, convenient and swift, safety is saved worry.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done and to be described in further detail:
With reference to Fig. 1; The gas nozzle that a kind of flow is adjustable; Comprise nozzle body 4 with air inlet 2 and gas outlet 1; The airtight needle-valves 3 that are set with of telescopically in the nozzle body 4, needle-valve 3 front ends have the taper contraction front 3-1 of shutoff gas outlet fully, needle-valve can along the nozzle body inner chamber move and can with gas outlet 1 full open to totally-enclosed scope in the corresponding position of any aperture locate.
For adjusting atmospheric pressure better, nozzle body 4 inwalls have the guiding conical surface 4-1 that shrinks to the gas outlet.
Nozzle body 4 has screwed hole with gas outlet 1 another relative sidewall, and needle-valve 3 has and the airtight external screw thread that cooperates of nozzle body screwed hole, and is through threaded engagement metering pin valve position and then adjust the gas port aperture, simple in structure, easy to operate.Needle-valve 3 rear ends have the slot 3-2 that can cooperate with screwdriver, can adjust the gas port aperture through screwdriver, not only guarantee to operate facility but also effectively prevent maloperation.
Nozzle body 4 has the two ends that tubular cavity gas outlet 1 and screwed hole lay respectively at tubular cavity, and needle-valve 3 can move in tubular cavity, and air inlet 2 is positioned at the side of tubular cavity.
Experiment showed, that the bus of end toper contraction front and axis angle a are preferred 10 ° ~ 20 ° before the needle-valve 3 for the discharge coefficient that makes nozzle reaches optimum.Preferred 45 ° ~ 70 ° of the bus of nozzle body inwall guiding conical surface 4-1 and axis angle b.
Though the utility model is through illustrating and describe with reference to preferred embodiment; But those skilled in the art should understand, and can be not limited to the description of present embodiment; In the scope of claims, can make the various variations on form and the details.
