Description
Technical field
The utility model belongs to cleaning machine technical field, refers in particular to the high-efficiency and energy-saving type plunger pump in a kind of cleaning machine.
Background technology
Operationally, the pressure that outer check valve is born is discharge pressure (under normal operation) to the pump of cleaning machine, and interior
Check valve is water suction check valve, and its pressure born is substantially that the half of outer check valve is also few；The tube wall power of valve block and valve seat
Mainly have at 2 points, be some the elastic force of one-way valve spring (this point is especially embodied in the process that just water suction or water are not drunk up)；Two
It is the pressure of (strong) generation of hydraulic pressure.Check valve only is closed by one-way valve spring when cleaning machine or pump just begin to use,
So as to produce unidirectional vacuum state；Inside and outside one-way valve spring is such as designed to identical elastic force, then due to the two use environment not
With so as to the pressure difference produced, both sealing properties are inconsistent under equal machining accuracy, and causing the efficiency of pump reduces.
The content of the invention
The purpose of this utility model is to provide a kind of high-efficiency and energy-saving type plunger pump, and inside and outside one-way valve spring is designed into difference
Elastic force, compensate for the pressure difference that use environment difference is produced, the sealing of the two is able to reach one under equal machining accuracy
Cause, so as to improve the efficiency of pump.
What the purpose of this utility model was realized in：It is provided with a kind of high-efficiency and energy-saving type plunger pump, including cylinder body, cylinder body
Operating room, plunger is stretched into operating room, and operating room is connected with intake tunnel and exhalant canal, and intake tunnel is provided with interior unidirectional
Valve, exhalant canal is provided with outer check valve, and internal check valve ensures fluid from intake tunnel to operating room's one-way flow, outer check valve
Ensure fluid from operating room to exhalant canal one-way flow, it is characterised in that：Spring force in internal check valve is more than outer unidirectional
Spring force in valve.
It is preferred that, the concrete structure of the internal check valve and outer check valve is：Including unidirectional valve bonnet and one-way valve seat, unidirectionally
Valve bonnet is fixed on one-way valve seat afterbody, and the end face that both coordinate is respectively equipped with back-off and fastened by the axial grafting of back-off；Unidirectionally
Spring and check valve sheet are provided between valve bonnet and one-way valve seat, check valve sheet is compressed and covers going out in one-way valve seat afterbody by spring
On the mouth of a river.
It is preferred that, the back-off structure is：One-way valve seat afterbody is raised provided with annular, and annular convex head is provided with outer
Flange；The check valve capouch portion is provided with outer annular protrusion, and outer annular protrusion head is provided with in-flanges；Annular projection stretches into outer
Annular protrusion endoporus, flanging and in-flanges are mutually twisted, and outer annular protrusion is pushed against one-way valve seat tail end face.
It is preferred that, the raised female coaxial with one-way valve seat of the annular, check valve sheet is resisted against annular punching shaft
In the opening in portion.
It is preferred that, the opening of the annular convex head is provided with taper surface, and the check valve sheet periphery is provided with corresponding
Taper surface.
It is preferred that, the one-way valve seat periphery is provided with the seal groove for being used for assembling sealing ring.
The utility model is prominent and beneficial compared with prior art to be had the technical effect that：
During pump work, its plunger drives by the eccentric rotary of pump shaft, moves back and forth；When being drawn outside plunger, chamber pressure
Reduction, outer closed check valve, when the elastic force of internal check valve is less than the pressure of intake tunnel with work room pressure sum, interior list
Opened to valve, improve internal check valve spring force, it is ensured that the vacuum of operating room；When being pushed away in plunger, work is pressure liter
Height, internal check valve is closed, when chamber pressure is higher than outer one-way valve spring elastic force and exhalant canal pressure sum, outer check valve
Open, liquid discharge.
As can be seen here, the pressure that outer check valve is born is discharge pressure, and internal check valve is water suction check valve, what it bore
The outer check valve of pressure ratio is much less, and one-way valve spring elastic force is high outside the ratio that the elastic force of internal check valve spring is designed, then balances
Use environment is different so that the pressure produced is different, and both sealing properties are able to enough consistent, raising under equal machining accuracy
The efficiency of pump.
