Abstract
The utility model relates to a high pressure cleaner, which comprises a power setting, a transmission gear and a plunger pump. The plunger pump has a low pressure chamber and a high pressure chamber; wherein, the high pressure chamber is communicated with a pressure adjusting device. The utility model can adjust the water exit pressure of the high pressure cleaner conveniently through the pressure adjusting device; by adopting a direct-acting relief valve, the cleaner can maintain a stable water exit pressure and at the same time, the direct-acting relief valve can be taken as the safe valve.
Description
(1) technical field
The utility model relates to a kind of jetting machine.
(2) background technology
Existing jetting machine is made up of power set, transmission device and plunger displacement pump usually, power set can adopt motor, diesel engine, gasoline engine etc., transmission device can adopt driving gear set, plunger displacement pump is made up of crankshaft connecting rod system, plunger and appurtenances usually, has low-pressure cavity and high pressure chest on the plunger displacement pump.Existing jetting machine generally can not pressure regulation, only is provided with safety valve usually.
(3) utility model content
Technical problem to be solved in the utility model is to provide a kind of jetting machine with pressure regulatory function.
Described jetting machine comprises power set, transmission device, plunger displacement pump, and described plunger displacement pump has low-pressure cavity and high pressure chest, and described high pressure chest is communicated with pressure-regulating device.
Further, described pressure-regulating device is a direct-acting overflow valve.
Further, described direct-acting overflow valve comprises valve body, spool, pressure spring, adjusting rod, adjusting nut, described adjusting rod is provided with lock-nut, and described adjusting nut is threaded with valve body and the head inwall of adjusting nut withstands described adjusting rod.
Further again, the liquid return hole of described direct-acting overflow valve is communicated with described low-pressure cavity.
The utility model can be regulated the pressure of jetting machine water outlet easily by pressure-regulating device, adopts direct-acting overflow valve can keep the discharge pressure of cleaning machine stable, and direct-acting overflow valve can also use as safety valve simultaneously.
(4) description of drawings
Fig. 1 is the plunger displacement pump structural representation of the described jetting machine of embodiment.
(5) specific embodiment
The utility model is described in further detail below in conjunction with embodiment, but protection domain of the present utility model is not limited to this.
With reference to Fig. 1, a kind of jetting machine comprises power set, transmission device, plunger displacement pump, and described plunger displacement pump has low-pressure cavity 1 and high pressure chest 2, and described high pressure chest 2 is communicated with pressure-regulating device 3.Described pressure-regulating device 3 is a direct-acting overflow valve.Described direct-acting overflow valve comprises valve body 4, spool 5, pressure spring 6, adjusting rod 7, adjusting nut 8, described adjusting rod 7 is provided with lock-nut 9, and described adjusting nut 8 is threaded with valve body 4 and the head inwall of adjusting nut 8 withstands described adjusting rod 7.The liquid return hole of described direct-acting overflow valve is communicated with described low-pressure cavity 1.
When jetting machine of the present utility model was worked, when the pressure of high pressure chest 2 was higher than spring force, spool 5 was opened, and water flows back to low-pressure cavity 1 by liquid return hole.Lock-nut 9 is used for determining this excessive maximum pressure of valve work that rolls.Pretightning force by turn adjusting nut 8 drive adjusting rods 7 and then change pressure spring 6 just can change oil pressure relief, thereby regulate the discharge pressure of jetting machine easily.
Claims (4)
