Abstract
The stacked jetting machine plunger pump of a kind of step, comprise the pump housing, the pump housing is shaped with water intake, water outlet and plunger active chamber, in plunger active chamber, plunger is set, step type valve pocket processed is opened between described water intake and water outlet, described step type valve pocket comprises into water valve pocket and water outlet valve pocket, step is provided with between water inlet valve pocket and water outlet valve pocket, water inlet valve pocket is communicated with plunger active chamber through inclined hole, water one-way valve is installed in water inlet valve pocket, in water outlet valve pocket, water one-way valve is installed out, and the valve body going out water one-way valve rests on step.Its beneficial effect is: water feeding one-way valve with go out water one-way valve installs simply, convenient, compact structure, plunger cavity clearance is little, the volumetric efficiency of raising pump, enhancing suction capacity.
Description
Technical field
The utility model relates to plunger pump, particularly relates to the stacked jetting machine plunger pump of a kind of step.
Background technique
At present, jetting machine plunger pump on market, its water feeding one-way valve and go out water one-way valve and be independently arranged in the pump housing of plunger pump, namely water feeding one-way valve is arranged on water intake side, goes out water one-way valve and is arranged on water outlet side, and water feeding one-way valve is communicated with by water inlet and outlet through hole with going out between water one-way valve, and be connected with plunger active chamber through plunger through hole, water inlet and outlet through hole and plunger through hole cause plunger clearance large, and make the volumetric efficiency of pump low, suction capacity is poor.
Summary of the invention
The purpose of this utility model is the shortcoming in order to overcome prior art, there is provided a kind of and adopt step closed assembly mode, water feeding one-way valve and go out water one-way valve and install compact, plunger clearance is little, improves the stacked jetting machine plunger pump of a kind of step of volumetric efficiency and suction capacity.
The technological scheme of the stacked jetting machine plunger pump of a kind of step of the utility model is: comprise the pump housing, the pump housing is shaped with water intake, water outlet and plunger active chamber, in plunger active chamber, plunger is set, it is characterized in that between described water intake and water outlet, opening step type valve pocket processed, described step type valve pocket comprises into water valve pocket and water outlet valve pocket, step is provided with between water inlet valve pocket and water outlet valve pocket, water inlet valve pocket is communicated with plunger active chamber through inclined hole, water one-way valve is installed in water inlet valve pocket, in water outlet valve pocket, water one-way valve is installed out, and the valve body going out water one-way valve rests on step.
The stacked jetting machine plunger pump of a kind of step of the utility model, main feature opens step type valve pocket processed between described water intake and water outlet, described step type valve pocket comprises into water valve pocket and water outlet valve pocket, step is provided with between water inlet valve pocket and water outlet valve pocket, water one-way valve is installed in water inlet valve pocket, in water outlet valve pocket, water one-way valve is installed out, and the valve body going out water one-way valve rests on step.When plunger carries out suction campaign, water feeding one-way valve is opened, and water enters water feeding one-way valve from water intake, then enters in plunger active chamber by inclined hole; When plunger complete suck motion after start discharge motion, water feeding one-way valve close, water outlet one-way valve opens, water is entered out in water one-way valve by inclined hole, then enter water outlet ejection.Its beneficial effect is: water feeding one-way valve with go out water one-way valve installs simply, convenient, compact structure, plunger cavity clearance is little, the volumetric efficiency of raising pump, enhancing suction capacity.
The stacked jetting machine plunger pump of a kind of step of the utility model, described step type valve pocket is shaped with opening, installs gland in opening.Had opening, be convenient to water feeding one-way valve and go out water one-way valve install, gland blocks opening.
Accompanying drawing explanation
Fig. 1 is a kind of step of the utility model stacked jetting machine plunger pump structure schematic diagram.
Embodiment
The utility model relates to the stacked jetting machine plunger pump of a kind of step, as shown in Figure 1, comprise the pump housing 1, the pump housing is shaped with water intake 2, water outlet 3 and plunger active chamber 4, plunger 5 is set in plunger active chamber, step type valve pocket processed is opened between described water intake 2 and water outlet 3, described step type valve pocket comprises into water valve pocket 6 and water outlet valve pocket 7, step 8 is provided with between water inlet valve pocket 6 and water outlet valve pocket 7, water inlet valve pocket is communicated with plunger active chamber 4 through inclined hole 14, water one-way valve 9 is installed in water inlet valve pocket, water one-way valve 10 is installed out in water outlet valve pocket 7, and the valve body 11 going out water one-way valve 10 rests on step 8.The main feature of this programme opens step type valve pocket processed between described water intake 2 and water outlet 3, described step type valve pocket comprises into water valve pocket 6 and water outlet valve pocket 7, step 8 is provided with between water inlet valve pocket 6 and water outlet valve pocket 7, water one-way valve 9 is installed in water inlet valve pocket, water one-way valve 10 is installed out in water outlet valve pocket 7, and the valve body 11 going out water one-way valve 10 rests on step 8.When plunger 5 carries out suction campaign, water feeding one-way valve 9 is opened, and water enters water feeding one-way valve 9 from water intake 2, then enters in plunger active chamber 4 by inclined hole 14; When plunger 5 complete suck motion after start to discharge motion, water feeding one-way valve 9 is closed, and go out water one-way valve 10 and open, water is entered out in water one-way valve 10 by inclined hole 14, then enters water outlet 3 and spray.Its beneficial effect is: water feeding one-way valve with go out water one-way valve installs simply, convenient, compact structure, plunger cavity clearance is little, the volumetric efficiency of raising pump, enhancing suction capacity.Described step type valve pocket is shaped with opening 12, installs gland 13 in opening.Had opening, be convenient to water feeding one-way valve and go out water one-way valve install, gland blocks opening.
