Abstract
The invention discloses a combined type piston suction one-way valve for a piston pump. The combined type piston suction one-way valve comprises a cylindrical piston body (1). A valve rod (6) is connected to the axis of the piston body (1). A sealing ring (2) and a guide sleeve (3) are arranged on the outer circle of the lateral side of the piston body (1). The direction in which liquid is pressed to be discharged in a hydraulic cylinder through the piston body (1) is defined to be the front direction, and the opposite direction is defined to be the back direction. The combined type piston suction one-way valve is characterized in that a plurality of liquid inlet cylinder holes (11) of the suction one-way valve are formed between the front end face and the back end face of the piston body (1); a suction valve plate (4) is arranged on the piston valve rod (6) in a sleeving mode and in the mode of being capable of sliding in the axial direction, a spring (5) is arranged between the suction valve plate (4) and the valve rod (6), the suction valve plate (4) abuts against the front end face of the piston body (1) through the spring (5), and annular groove openings in the front ends of the liquid inlet cylinder holes (11) are plugged by the suction valve plate (4); the liquid inlet cylinder holes (11) are formed in the piston body (1) in a hydraulic cylinder hole, and meanwhile the liquid inlet cylinder holes (11) serve as suction one-way valve holes.
Description
Technical field
The present invention relates to a kind of suction individual event valve of reciprocating pump.
Background technique
Piston is reciprocating pump fluid cylinder end critical component with sucking one-way valve, and suction 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 present invention will overcome the above-mentioned shortcoming of prior art, provides a kind of reciprocating pump built-up piston to suck one-way valve.
Reciprocating pump built-up piston sucks one-way valve, comprise the piston body 1 in cylindrical shape, the axis of described piston body 1 connects valve rod 6, the side cylindrical of described piston body 1 is provided with seal ring 2, guide sleeve 3, before the direction of piston body 1 pressure liquid in fluid cylinder is orientated as, after contrary direction is defined as, it is characterized in that: the feed liquor cylinder holes 11 being provided with multiple suction one-way valve between the front-end face of piston body 1 and ear end face; Sucking valve plate 4 can be enclosed within described piston valve spindle 6 by axial direction slidably, suck between valve plate 4 and described valve rod 6 and be provided with spring 5, suction valve plate 4 holds out against on the front-end face of piston body 1 by spring 5, sucks the front end annular channel opening that valve plate 4 blocks feed liquor cylinder holes 11; It is also suck unidirectional valve opening that described feed liquor cylinder holes 11 is arranged on the piston body 1 in cylinder port simultaneously.
It is integral that the liquid piston of reciprocating pump fluid cylinder end is sucked one-way valve designs by the present invention, both simplified the structure, save material, avoid again the structure drawback that conventional reciprocating pump liquid cylinder existence suction one-way valve and cylinder port intersect vertically, prevent under alternate load effect, hole infall pressure is concentrated, and causes the problem of inefficacy easy to crack.
Advantage of the present invention is:
1. piston body is combined into piston type valve seat with suction valve seat, possesses piston body and the function sucking valve seat simultaneously.
2. piston type valve seat realizes two kinds of functions, has saving material; Suction valve adopts double flow channel design, and area of passage is large, and hydraulic loss is little, and efficiency is high; One-way valve Lift is little, and vibration noise is little, and the life-span is long.
3. suck through large in check valve spring, spring string diameter is large, and stress is little, and the life-span is long.
4. inlet opening 11 is arranged on the piston body 1 in cylinder port.Avoid conventional piston pump liquid cylinder suction valve opening and cylinder port to intersect vertically, prevent under alternate load effect, hole infall pressure is concentrated, and causes easy-rupturing to lose efficacy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention
Embodiment
Below in conjunction with accompanying drawing, further illustrate the present invention:
Reciprocating pump built-up piston sucks one-way valve, comprise the piston body 1 in cylindrical shape, the axis of described piston body 1 connects valve rod 6, the side cylindrical of described piston body 1 is provided with seal ring 2, guide sleeve 3, before the direction of piston body 1 pressure liquid in fluid cylinder is orientated as, after contrary direction is defined as, it is characterized in that: the feed liquor cylinder holes 11 being provided with multiple suction one-way valve between the front-end face of piston body 1 and ear end face; Sucking valve plate 4 can be enclosed within described piston valve spindle 6 by axial direction slidably, suck between valve plate 4 and described valve rod 6 and be provided with spring 5, suction valve plate 4 holds out against on the front-end face of piston body 1 by spring 5, sucks the front end annular channel opening that valve plate 4 blocks feed liquor cylinder holes 11; It is also suck unidirectional valve opening that described feed liquor cylinder holes 11 is arranged on the piston body 1 in cylinder port simultaneously.
Suction one-way valve and piston do synchronous reciprocating and move.When piston moves backward, fluid cylinder volume increases, and forms vacuum; Under inlet liquid pressure, suck the pressure that valve plate 4 overcomes spring 5, throw off from the front end annular channel opening of feed liquor cylinder holes 11, suck one-way valve and open, the medium in piston rear entry pipeline is drawn in piston fluid cylinder; When piston advances forward, suck closed check valve, at seal ring 2 with under the effect of discharge one-way valve, pressure raises, and discharges one-way valve and opens, medium supercharging in pumping cylinder discharged.
Content described in this specification embodiment is only enumerating the way of realization of inventive concept; protection scope of the present invention should not be regarded as being only limitted to the concrete form that embodiment states, protection scope of the present invention also and conceive the equivalent technologies means that can expect according to the present invention in those skilled in the art.
