Abstract
The utility model relates to a plunger pump valve body comprising the valve body. A suction valve cavity and a discharge valve cavity are respectively and coaxially formed in the front and back ends of the valve body, a suction valve and a discharge valve are correspondingly mounted in the two cavities respectively, a straightening shell is coaxially connected with the end portion of the valve body, on one side of the discharge valve, and a cylinder sleeve and a conical sleeve high in hardness are respectively and coaxially mounted between the suction valve and the valve body as well as between the discharge valve and the valve body. The plunger pump valve body has the advantages that since the cylinder sleeve high in hardness is coaxially mounted between the suction valve cavity and the discharge valve cavity, wear-resisting property of the valve body is effectively improved and service life thereof is improved; in addition, maintenance is lowered by only having the cylinder sleeve replaced after wear of the valve body; the cylinder sleeve provided with a conical surface on the outer edge is convenient to mount and demount, and thus maintenance time can be saved.
Description
Technical field
The utility model belongs to the plunger pump technique field, specifically, is a kind of plunger pump valve body.
Background technique
Along with the renewal of oil well operation technology, the stability of pressure, discharge capacity, suction capacity and the pump efficiency of cementing truck is had higher requirement.Therefore when high-voltage construction, the requirement to plunger pump valve body is also just higher, common plunger pump valve body adopts stainless steel, its wear resistance is poor, due to frequent and suction valve and the friction of discharge valve, inner chamber easily weares and teares, occur must changing the valve body after wearing and tearing, so not only waste a large amount of manpowers, and improved the cost of plunger pump.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, reduce maintenance cost, improve the plunger pump valve body in working life.
Scheme of the present utility model is achieved in that
A kind of plunger pump valve body, comprise the valve body, this valve body rear and front end coaxially is shaped with respectively a suction valve cavity and discharges the valve cavity, be separately installed with in corresponding two cavitys and suck valve and discharge valve, at the coaxial righting shell that connects of the valve body end of discharging valve one side, described suction valve, discharge coaxial installation one cylindrical sleeve of difference between valve and valve body.
And the outer rim of described cylindrical sleeve is conical surface.
And described cylindrical sleeve is the alloyed steel material.
And, coaxially be shaped with respectively two annular grooves on described valve body outer rim.
And described righting outer casing inner wall coaxially is embedded with two Returnning springs, and one be that left-handed spring, one are the dextrorotation spring, and these two spring coaxial packages together.
And, the outer rim of described valve body portion radially is shaped with and some the second straight holes that suck the valve cavity and be communicated with, coaxially be shaped with a cylindrical cavity be communicated with discharge valve cavity in the valve rear body, this cylindrical cavity is shaped with a plurality of circular holes with in this valve body coaxial the connection, described suction valve outboard end radially is shaped with some the first straight holes, and the suction valve outer rim in the first straight hole position is shaped with screw thread.
And described discharge valve is identical with the diameter that sucks valve.
And on the outer rim of described righting shell, spaced radial is shaped with some righting shell aperture, in the end of this righting shell, the inboard limited ring of installing is shaped with screw thread in the end of righting shell.
Advantage of the present utility model and good effect are:
1, the Ben Faner body has the cylindrical sleeve of higher hardness by coaxial installation one in sucking valve cavity and discharge valve cavity, effectively improve the wear-resisting property of valve body, thereby improved its working life, only needed to change cylindrical sleeve after the valve body wear and get final product, reduced maintenance cost.
2, in the Ben Faner body, the outer rim of cylindrical sleeve is a conical surface, easy for removal and installation, effectively saves engineering time.
3, the Ben Faner body is discharged coaxial sleeve on valve two springs is housed, and these, two springs be that left-handed spring, one are the dextrorotation spring, has guaranteed that the discharge valve is stressed when working evenly not topple over, and has improved the stability of plunger pump work.
4, the utility model is simple in structure, design science is reasonable, is easy to realize, working stability is reliable, effectively improves the working life of plunger pump, has reduced maintenance cost.
The accompanying drawing explanation
Fig. 1 is partial sectional view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail.
A kind of plunger pump valve body, as shown in Figure 1, comprise valve body 3, this valve body rear and front end coaxially is shaped with respectively a suction valve cavity and discharges the valve cavity, be separately installed with suction valve 1 in corresponding two cavitys and discharge valve 5, in the valve body end of discharging valve one side, by engage thread, coaxially connecting a righting shell 6.
Innovative point of the present utility model is:
Between described suction valve and valve body, co-axial seal is installed a cylindrical sleeve 14, this cylindrical sleeve is connected with the interference of valve body, for easy accessibility, between discharge valve and valve body, co-axial seal is installed a taper sheath 11, this taper sheath outer rim is conical surface, to adopt mode and the valve body of interference fit to link together equally, described cylindrical sleeve and taper sheath all adopt alloy steel material, effectively improve the wear resistance of valve body, in the working life of therefore having improved the valve body, reduce maintenance cost.
In the present embodiment, coaxially be shaped with respectively two annular grooves 4 on described valve body outer rim, be embedded with respectively two sealing joint strip (not shown)s in these two annular grooves, this righting outer casing inner wall coaxially is embedded with two Returnning springs 9, and one is that left-handed spring, one are the dextrorotation spring, together, purpose is that expulsion valve you stressedly evenly do not toppled in when work to these two spring coaxial packages.
The outer rim of described valve body portion radially is shaped with and some the second straight holes 2 that suck the valve cavity and be communicated with, coaxially be shaped with a cylindrical cavity 12 be communicated with discharge valve cavity in the valve rear body, this cylindrical cavity is shaped with a plurality of circular holes 13 with in this valve body coaxial the connection, described suction valve outboard end radially is shaped with some the first straight holes 16, and the suction valve outer rim in the first straight hole position is shaped with screw thread 15.
Described discharge valve is identical with the diameter that sucks valve, thereby has realized the standardization of part, and is easy to process the cavity that holds two valves on the valve body, has effectively improved working efficiency.
