Abstract
Reciprocating pump combined liquid cylinder cap discharges one-way valve, comprise fluid cylinder lid 1, described fluid cylinder lid 1 has one roughly in cylindrical body, the cylindrical side of described body is provided with seal ring 41, it is characterized in that: described body is provided with annular groove 11, discharging spool 2 is enclosed within described annular groove 11, and discharging spool 2 can slide along the direction of the axis of described body, discharges between spool 2 and groove 11 and is provided with spring 3; What be provided with multiple discharge one-way valve between the wall of described annular groove 2 and the end face of described body goes out cylinder port 12, described to go out on fluid cylinder lid 1 that cylinder port 12 is arranged in cylinder port be also unidirectional valve opening simultaneously, and described discharge spool 2 is blocked and described gone out the annular opening 122 that cylinder port 12 is positioned at a side of the wall end face of described annular groove.
Description
Technical field
The utility model relates to a kind of reciprocating pump fluid cylinder lid and discharges one-way valve.
Background technique
Fluid cylinder lid is reciprocating pump fluid cylinder end critical component with discharging one-way valve, and discharge one-way valve and the cylinder port of conventional reciprocating pump liquid cylinder intersect vertically, and under alternate load effect, hole infall pressure is concentrated, and causes the problem of inefficacy easy to crack.
Summary of the invention
The utility model will overcome the above-mentioned shortcoming of prior art, provides a kind of reciprocating pump fluid cylinder lid to discharge one-way valve.
Reciprocating pump combined liquid cylinder cap discharges one-way valve, comprise fluid cylinder lid 1, described fluid cylinder lid 1 has one roughly in cylindrical body, the cylindrical side of described body is provided with seal ring 41, it is characterized in that: described body is provided with annular groove 11, discharging spool 2 is enclosed within described annular groove 11, and discharging spool 2 can slide along the direction of the axis of described body, discharges between spool 2 and groove 11 and is provided with spring 3; What be provided with multiple discharge one-way valve between the wall of described annular groove 2 and the end face of described body goes out cylinder port 12, described to go out on fluid cylinder lid 1 that cylinder port 12 is arranged in cylinder port be also unidirectional valve opening simultaneously, and described discharge spool 2 is blocked and described gone out the annular opening 122 that cylinder port 12 is positioned at a side of the wall end face of described annular groove.
The utility model just fluid cylinder lid is integral with discharge one-way valve designs, both simplified the structure, save material, avoid again the structure drawback that conventional reciprocating pump liquid cylinder existence suction discharge one-way valve outage and cylinder port intersect vertically, prevent under alternate load effect, hole infall pressure is concentrated, and causes the problem of inefficacy easy to crack.
The utility model has the advantages that:
1. cylinder cap and the integrated design of discharge one-way valve seat, have the high pressure sealing of fluid cylinder lid and the dual functions of discharging one-way valve seat.
2. discharge one-way valve and adopt double flow channel structural design, area of passage is large, and hydraulic loss is little, and efficiency is high.
3. discharge one-way valve radial dimension large, and adopt double flow channel structure, area of passage is large, and valve plate lift is little, and closedown impulsive load is little, and vibration noise is low, and the life-span is long.
4. discharge through large in check valve spring, spring string diameter is large, and stress is little, and the life-span is long.
5. cylinder port be discharge unidirectional valve opening liquid outlet opening 12 be arranged on the fluid cylinder lid 1 in cylinder port.The structure drawback avoiding conventional reciprocating pump liquid cylinder to there is discharge valve aperture and cylinder port intersecting vertically, under can preventing alternate load effect, hole infall pressure is concentrated, and produces the problem of inefficacy easy to crack.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
Fig. 2 is the right elevation of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, further illustrate the utility model:
Reciprocating pump combined liquid cylinder cap discharges one-way valve, comprise fluid cylinder lid 1, described fluid cylinder lid 1 has one roughly in cylindrical body, the cylindrical side of described body is provided with seal ring 41, it is characterized in that: described body is provided with annular groove 11, discharging spool 2 is enclosed within described annular groove 11, and discharging spool 2 can slide along the direction of the axis of described body, discharges between spool 2 and groove 11 and is provided with spring 3; What be provided with multiple discharge one-way valve between the wall of described annular groove 2 and the end face of described body goes out cylinder port 12, described to go out on fluid cylinder lid 1 that cylinder port 12 is arranged in cylinder port be also unidirectional valve opening simultaneously, and described discharge spool 2 is blocked and described gone out the annular opening 122 that cylinder port 12 is positioned at a side of the wall end face of described annular groove.
Discharge one-way valve and piston do synchronous reciprocating and move.Before the direction of piston body 1 pressure liquid in fluid cylinder is orientated as, after contrary direction is defined as.When piston advances forward, under piston seal effect, under fluid pressure raises, spool 2 overcomes the pressure of spring 3, throws off from the opening going out cylinder port 12, discharges one-way valve and opens, medium supercharging in pumping cylinder discharged.When piston moves backward, discharge closed check valve, in sealing with under the effect of discharge one-way valve, volume increases, and forms vacuum, is drawn in piston nose fluid cylinder by the medium in piston rear end fluid cylinder and preserves.
Content described in this specification embodiment is only enumerating the way of realization that model utility is conceived; protection domain of the present utility model should not be regarded as being only limitted to the concrete form that embodiment states, protection domain of the present utility model also and conceive the equivalent technologies means that can expect according to the utility model in those skilled in the art.
