Description
Technical field
The present invention relates to a kind of dual fail-safe spray gun with protection sleeve pipe, belongs to high-pressure fluid spraying technique field.
Background technique
Use the structure composition spray gun of hard tube rear portion connection hose total currently, high-pressure fluid sprays used body of spray gun rifle
At.Wherein hose and hard tube junction are easiest to rupture and generate leakage.If hard tube itself is defective in quality, or work in by
To damage, it is also extremely easily broken generation leakage.It is in close contact with upper bit and man with a gun's body, existing spray gun structure does not have
If duplicate protection, which will generate leakage, directly to generate directly injury to man with a gun.
Summary of the invention
Above-mentioned existing spray gun structure there are aiming at the problem that, the present invention provide it is a kind of with protection sleeve pipe dual fail-safe spray
Rifle, to provide second protection when realizing that spray gun rupture generates leakage, realization protects purpose to man with a gun to greatest extent.
To achieve the goals above, the technical solution adopted by the present invention is that: a kind of dual fail-safe spray gun with protection sleeve pipe,
Including spray head and the high-pressure hose being connected, further include protection sleeve pipe, foregrip and rear handle be installed in protection sleeve pipe, after hold
Buttstrap is equipped with, protection sleeve pipe front is furnished with the inserted sheet and locking nut of stationary nozzle, and foregrip and rear handle are respectively arranged with dynamic circuit connector
Switch.
The beneficial effects of the present invention are: the spray head and protective case of high-pressure hose will be connected to by inserted sheet and locking nut
Pipe fits together, it is possible thereby to realize that protection sleeve pipe realizes second protection when pressure duct rupture and leakage.By foregrip with
The circuit control system pressure of dynamic circuit connector switch composition above handle afterwards, needing two switches to be closed at system can just boost,
Any one switch disconnects system decompression, and control switch is made to realize dual fail-safe.

Specific embodiment
The present invention will be further explained below with reference to the attached drawings.
As shown in figure 3, the dual fail-safe spray gun with protection sleeve pipe, including spray head 5 and the high-pressure hose 2 that is connected,
It further include protection sleeve pipe 1, the foregrip 8 and rear handle 9 installed in protection sleeve pipe 1, rear handle 9 are equipped with buttstrap 7, protection sleeve pipe 1
Front is furnished with the inserted sheet 4 and locking nut 3 of stationary nozzle 5, and foregrip 8 and rear handle 9 are respectively arranged with dynamic circuit connector switch 10.
The course of work: the spray head 5 for being connected with high-pressure hose 2 is placed in protection sleeve pipe 1 to be fixed by inserted sheet 4 and locking nut 3
In protection sleeve pipe 1, the foregrip 8 and rear handle 9 that protection sleeve pipe 1 assembles above, buttstrap 7, dynamic circuit connector switch 10 collectively constituted
Spray gun assembly.
Lance ejection handling situations one, system start spraying operation, and dynamic circuit connector switch 10 is closed, and system boosting, nozzle 7 sprays
Operation, system job are completed, and dynamic circuit connector switch 10 disconnects, system decompression, and nozzle 7 stops spraying operation.
Lance ejection handling situations two, system start spraying operation, and dynamic circuit connector switch 10 is closed, and system boosting, nozzle 7 sprays
Operation, high-pressure hose 2 or junction rupture and leakage during spraying operation, protection sleeve pipe 1 prevent leakage liquid to armed people
Member's injection, dynamic circuit connector switch 10 turn off, system decompression.
Due to protection sleeve pipe using high-strength material manufacture, can effective protection liquid injection, spray gun assembly dress there are two
The circuit of dynamic circuit connector switch composition, pressure release is avoided system switching maloperation by any one switch disconnection system to greatest extent, maximum
Limit protects the safety of man with a gun.
Spray gun assembly, protection sleeve pipe 1 are assembled with 9 two handles of foregrip 8 and rear handle above, and being equipped on rear handle 9 can
Flexible buttstrap 7, constituting consolidate man with a gun can in the case where larger recoil strength by shoulder and the armed operation of both hands
Control spray gun.
Below with reference to the embodiment of Fig. 1 Fig. 2 and Fig. 5, the assembling mode of Fig. 1 and Fig. 2 are introduced, Fig. 1 is connected with high-pressure hose 2
Spray head 5 be placed in Fig. 2 protection sleeve pipe 1, be fixed in protection sleeve pipe 1 by inserted sheet 4 and locking nut 3.
Inserted sheet 4 can also be spun on to be replaced on spray head 5 using round nut reaches same purpose.
Locking nut 3 can also reach same purpose using the replacement of the forms such as flange.
In order to reduce the maloperation of spray gun, there are two the circuit of dynamic circuit connector switch composition, one of switches for spray gun assembly dress
It disconnects system decompression and plays the role of dual fail-safe.
Above-described specific example, to the purpose of the present invention, technical scheme and beneficial effects have been carried out further in detail
Illustrate, it should be understood that the above description is only a specific example of the present invention, is not intended to restrict the invention, it is all at this
Within spirit and principle, any modification made, equivalent replacement, improve etc., it should be included in protection scope of the present invention
Within.
