Weight function；Using multiple flow passages structure design, multiple excessively stream runners are set on valve seat, big with area of passage, hydraulic loss is small,
Be conducive to improving the efficiency of pump；
(2) Outlet check valves radial dimension is big, and uses multiple flow passages structure, and area of passage is big, and valve plate lift is small, closes punching
Hit load small, vibration noise is low, long lifespan；
(3) Outlet check valves mean diameter of coil is big, and spring string diameter is big, and stress is small, long lifespan；
(4) outlet valve seat is provided with pressure relief vent, can prevent from being built the pressure in outlet valve seat cavity.
(5) this Outlet check valves is applicable conveying air-liquid or gas-liquid mixed multinomial medium compression pump.
Brief description of the drawings
Fig. 1 is the structural representation of the embodiment of the present invention.
Specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing embodiment.
With reference to shown in Fig. 1, this compression pump is main by valve seat 1, sealing ring 2, valve plate 3, spring 4 with multiple flow passages Outlet check valves
And the assembling of the grade of pump cover 5 is constituted, wherein：Valve seat 1 is in stepped cylindrical body, and there is a cylindrical boss 17 its front portion.Pump cover 5 is relative
The end face of valve seat is provided with a circular trough, is available for the cylindrical boss 17 on valve seat spacing.During assembling, valve seat 1 is mounted in pump cover 5
On circular trough and both are fastened by bolt 6 and be connected in together, and sealing ring 2 is provided between valve seat and pump seat.And valve seat 1
Also separated by the cylindrical boss 17 on valve seat between pump cover 5 and form a big annular groove, described valve plate 3 and spring
4 are located at the big annular groove, specifically：Valve plate 3 is enclosed within the cylindrical boss 17 of valve seat, can axial slip, and valve plate 3
The spacing 7 for being available for valve plate to open journey of dividing a word with a hyphen at the end of a line is left between the end face of pump cover 5, because this Outlet check valves area of passage is big, valve
Lift is small, therefore the very little of spacing 7 between the two；Spring 4 is enclosed within valve plate 3, and its one end is connected with valve plate 3, the other end
It is connected with pump cover 5, may insure that valve plate 3 has good centering and sealing by this spring 4, in non-return valve operational,
May insure that N number of excessively stream runner of this check valve is synchronously turned on and off, without interference.This Outlet check valves mean diameter of coil is big, bullet
Spring string diameter is big, and stress is small, long lifespan.
The end face center in the outside of valve seat 1 is provided with a cavity 11, and cavity 11 has multiple pressure relief vents 12 to connect with end face, release
Hole 12 can prevent from being built the pressure in cavity.Be provided with the end face of valve seat boss side N (N be integer and N >=2) individual annular groove 13,14,
15, N number of annular groove is distributed with one heart around axis, and multiple inlet openings 16 are drilled with each annular groove, along annular groove week
To distribution.N number of excessively stream runner of valve seat is so made up of the N number of annular groove 13,14,15 on numerous inlet openings 16 and end face.
The N number of excessively stream runner 31,32,33 being made up of the annular slotted hole of N number of concentric distribution also is provided with the corresponding valve plate 3, so
Area of passage can further be increased, hydraulic loss is reduced；Can reduce Outlet check valves Lift again, reduce check valve open or
The angle of lag of closing, reduces backflow volumetric loss, improves the volumetric efficiency of pump；Can also reduce what check valve was turned on and off simultaneously
Speed, reduces impulsive force, reduces noise.
And the cylindrical side of valve seat 1 and pump cover 5 is equipped with sealing ring 2.
Be arranged on Outlet check valves in cylinder port using pump cover and outlet valve seat Combination Design by this Outlet check valves, is kept away
The structure drawback that conventional compression pump liquid cylinder body outlet spool valve intersects vertically with cylinder port is exempted from, can prevent in alternate load effect
Under, hole infall stress concentration produces the problem of fluid cylinder Cracking Failure.Meanwhile, both can reduce liquid cylinder highly, material-saving,
Liquid cylinder inner flow passage excessively stream can be improved again.And multiple flow passages are designed, area of passage is increased, reduce hydraulic loss, improve efficiency, and
And check valve Lift can be reduced, and reduce vibration, extend the life-span.
The operation principle of this Outlet check valves is as follows：Outlet check valves do synchronous reciprocating motion with piston.By piston in liquid
Before the direction of pressure liquid is orientated as in cylinder, after opposite direction is defined as.When piston advances forward, in piston seal effect
Under, fluid pressure rises relative superiority or inferiority, and valve plate overcomes the pressure of spring, is disengaged from the opening of excessively stream runner, and Outlet check valves are opened, by pump
Medium supercharging discharge in cylinder.When piston is moved backward, Outlet check valves are closed, under seal and Outlet check valves effect,
Volume increases, and forms vacuum, the medium in piston rear end fluid cylinder is drawn into piston nose fluid cylinder and is preserved.
And the valve seat shown in the present embodiment figure uses the structure of Split assembled with pump cover, but except this split knot
Outside structure, integrated design can also be used, will pump seat and the integral structure of seat design, can similarly realize hair of the invention
Improving eyesight.
The foregoing is only the preferred embodiment of the present invention, it is noted that for those of ordinary skills,
Under the premise of principle of the invention is not departed from, various remodeling or improvement can be carried out to the present invention, these are regarded as the present invention
Protection domain within.
