2. Description of the Related Art Problems to be Solved by the Related Art and Invention For example, an air spray type painting handgun has an inflow port connected to an outflow passage reaching the paint outlet of a nozzle chip at the tip of the gun and an external paint supply source. A valve chamber that communicates with the channel is provided, and an outlet for communicating with the paint atomization nozzle of the nozzle chip and an outlet for communicating with the paint pattern control outlet and an inlet connected to an external compressed air supply source are connected. By piercing the valve chambers, the valve bodies with operating rods projecting to the outside of the barrel are installed in both valve chambers so that they are always in contact with the valve mouth and kept closed. A normally closed paint opening / closing valve and a compressed air opening / closing valve are configured, and by pulling a trigger that engages with the protruding end of each operating rod, both operating rods are simultaneously pushed into the barrel and each valve body is pushed. Is separated from the valve opening, both on-off valves open, and the outflow path is Through this, the paint discharged from the paint discharge port is atomized by the compressed air discharged from the atomization discharge port and discharged while forming an elliptical shape by the compressed air discharged from the pattern control discharge port. About
It is designed to be painted, and these on-off valves are easily worn because the contact part between the valve body and the valve seat fitted in the valve mouth and the sealing part between the operating rod and the barrel are easily worn. However, in the past, the on-off valve was built into the barrel, so the entire barrel had to be disassembled when replacing the parts, which was a cumbersome and time-consuming task. There is a drawback that it takes time, and this is a problem common to not only the air spray type handgun but also the airless spray type handgun having only the on-off valve for paint built therein.

The operation and effect of the present invention is configured as described above, and when paint or air for paint atomization or paint pattern control is supplied into the barrel from each supply source, the paint or air is applied to the mounting surface of the barrel. The operating port of the on-off valve is pushed into the body by pulling the trigger pivotally supported on the barrel from the formed first port through the inlet of the on-off valve into the on-off valve without leaking and pulling the trigger pivotally supported on the barrel. Is opened and the above paint or air is discharged from the discharge port at the tip of the barrel through the second port without leaking from the outlet,
Since the on-off valve was unitized and attached to the barrel detachably, the work of replacing the internal parts of the on-off valve was done by disassembling the on-off valve from the barrel and preparing it as a spare. It can be easily and quickly installed by simply attaching the on-off valve, and if the on-off valve becomes unusable due to its life or irreparable failure, only the on-off valve needs to be replaced. Therefore, since the barrel itself can be used as it is, the cost can be kept low.

Open / close valve 3 for paint attached to the right rear part of barrel 1
Is a tubular body 30 having a flat fixing surface 31 formed on the outer side of the body 30 that is in close contact with the mounting surface 20 of the barrel 1. The fixing surface 31 is aligned with the feed port 21 of the barrel 1. Inlet to
An outlet 33 is formed which is aligned with 32 and the discharge port 22, and a hollow rear end portion that penetrates the body 30 in the front-rear direction is communicated with the inlet 32 by closing the open rear end with a screw lid 35. An inlet chamber 36 is formed, and a hollow central portion has a small-diameter outlet chamber communicating with the outlet 33 by screwing a bottomed cylindrical support member 37 at the front end to close the front.
38 is formed, and an O-ring 40 serving as a valve seat is fixed to the reduced diameter step portion of the inlet chamber 36 to form a valve port 41.
A valve body 42 that opens and closes the valve opening 41 by contacting and separating from the O-ring 40 from the 36 side
Is screwed to the rear end of the operating rod 45 protruding through the sliding hole 43 of the support body 37 to the front of the body 30, and is supported by the rear end surface of the engaging body 46 fixed to the front end of the operating rod 45. The elastic force of the compression coil spring 47 mounted between the body 37 and the back end surface of the body 37 causes the operating rod to move.
Since the valve element 42 contacts the O-ring 40 and is urged in the direction of closing the valve opening 41 while 45 projects forward,
The paint that flows into the outlet chamber 38 leaks to the outside from the sliding hole 43 of the support body 37 around the portion of the operating rod 45 exposed in the outlet chamber 38 so as to be held in the closed state. A metal bellows 48 for preventing the above is mounted, and a stopper 50 for adjusting the amount of paint to be discharged, in which the front end face 51 is inclined with respect to the axis, is provided on the inner periphery of the support body 37. Operation rod inside
The on-off valve 3 is mounted so as to be screwed by screwing the rear end portion while penetrating the engagement body 46 of 45, and this on-off valve 3 connects the inlet 32 on the inlet chamber 36 side to the feed port 21 of the barrel 1. In the exit room
The outlet 33 on the 38 side is aligned with the discharge port 22, respectively, and the O-rings 54, 54 fitted around the respective ports 21, 22 of the attachment surface 20 of the barrel 1 are used to attach the attachment surface 20 and the fixed surface 31. In order to prevent the paint from leaking from the gap between the two, the screw 80 is inserted through the body 30, screwed into the mounting surface 20 and tightened to be fixed so as to be detachable, and the engaging body 46 protruding from the stopper 50.
Of the trigger 9 supported by the barrel 1 corresponds to the slightly bulging contact portion 9a on the right side of the trigger 9. And trigger 9
When the lever is pulled, its abutting portion 9a abuts on the engaging body 46 and pushes it in, whereby the operating rod 45 moves rearward against the elastic force of the compression coil spring 47, and the valve body 42 causes the O-ring 40 to move. The valve opening 41 is opened apart from the valve opening 41, the paint flowing from the inlet 32 into the inlet chamber 36 flows from the valve opening 41 to the outlet chamber 38, and is sent to the paint outlet 10 of the barrel 1 through the outlet 33. When trigger 9
It is possible to keep the discharge amount of the paint constant by contacting the lower end portion of the front end surface 51 of the stopper 50, and in this case, the discharge amount of the paint becomes the maximum. For the maximum discharge amount, the stopper 50 is screwed with respect to the support 37 to change the amount of advancement and the direction of the inclination of the front end face 51 to adjust the pulling margin of the trigger 9 until it hits the stopper 50. The maximum opening degree of the valve opening 41 can be adjusted by changing the pushing amount of the valve.

1. A first port having a mounting surface formed on the outer surface of a barrel having a paint discharge port at its tip, and communicating with a supply source of paint or air for paint atomization or paint pattern control. And a second port communicating with the discharge port at the tip are formed side by side, an inflow port and an outflow port are formed side by side on a fixed surface formed on the outer surface of the body, and an operating rod that opens by pushing is provided on the front surface of the body. A normally-closed on-off valve that protrudes from the first port to the inflow port and the second port to the second port.
The ports are aligned with the outlets, respectively, and are detachably fixed to the barrel so that there is no gap between the mounting surface and the fixing surface, and the operating rod of the on-off valve is attached to the barrel.
