Abstract
The utility model discloses an easily-overhauled fluid check valve which comprises a valve body, a valve seat, a valve element, a valve rod, a guiding cavity, a spring, a water inlet and a water outlet. The easily-overhauled fluid check valve is characterized in that one side of the valve body is provided with a water outlet pipe inclined with the valve body, and the water outlet of the water outlet pipe is not in the same axis with the water inlet of the bottom of the valve body. A cavity of the water outlet pipe is communicated with a valve cavity through a valve cavity water passing opening of one side of the valve cavity, and the top end of the valve body is provided with a detachable valve cover. The valve element is manufactured by mixing teflon, copper powder, graphite, emery powder and silicate cement adhesives, manufacturing a blank and sintering the blank at a high temperature. The easily-overhauled fluid check valve has the advantages that the whole valve does not need to be detached from a pipeline when the valve is overhauled, only the valve cover at the top end of the valve body is opened, and overhauling operation can be conveniently performed with one person. The easily-overhauled fluid check valve is convenient to use, capable of saving labor and time, and capable of avoiding waste of labor and materials such as a steel pad when the valve is detached and installed each time. Compared with an existing check valve, the easily-overhauled fluid check valve is small in flow resistance, and the valve element made of high-abrasion-resistance materials is long in service life.
Description
Technical field:
The utility model relates to valve, relates generally to fluid non-return valve, particularly fluid check valve.
Background technique:
Be installed on the particularly safety check on mesohigh pipeline of fluid line, be mostly Through-conduit check valve, by flange, be connected on pipeline, when valve damages, particularly spool, spring etc. damage while needing to change, need whole safety check to unload down and carry out maintain and replace from pipeline, and then be installed on deferent.And charge and discharge valve often needs two or three people to complete from pipeline, very difficult, trouble.Moreover the flow resistance of existing safety check is larger, spool is not wear-resisting, and working life is short, and noise is large.
Summary of the invention:
The object of the utility model, to overhaul difficult problem and existing safety check flow resistance is large, short defect of spool life-span for need be from pipeline whole the unloading of existing safety check, a kind of easy maintenance fluid check valve is provided, maintenance needn't whole be unloaded from pipeline, convenience, saving of labor, save time, long service life, noise is little.
The technological scheme that realizes foregoing invention object is, easy maintenance fluid check valve, comprise spool 4 on valve body 1, valve pocket 2, bottom valve seat 3, valve seat, with valve rod 5, stem guiding chamber 6, valve rod spring 7, bottom water intake 8, the top water outlet 14 of spool one.Be characterised in that, valve body 1 one sides have the outlet pipe 13 tilting with valve body, and the water outlet of outlet pipe and valve body bottom water intake be not on same axis, and outlet pipe tube chamber 15 is connected with valve pocket 2 by the mistake mouth of a river 16 of valve pocket one side.Valve body top is provided with dismountable valve gap 10.
Technique scheme further preferably, the outlet pipe that described and valve body tilt, with the formed angle of valve body be α, and 35 °≤α≤50 °.
Further preferably, described spool 3 is by teflon, copper powder, graphite, diamantin, the agent of silicate gluing to technique scheme, through mixing, embryo processed, high temperature sintering, makes.
The beneficial effect that the utility model produces is:
The outlet pipe tilting in valve body one side setting and valve body, the water outlet of outlet pipe and valve body bottom water intake be not on same axis, and outlet pipe tube chamber is connected by the mistake mouth of a river and the valve pocket of valve pocket one side, and valve body top is provided with dismountable valve gap.When needs overhaul valve, be, will from pipeline, not unload by whole valve, and only valve body top valve gap need be opened, a people is inspection operation easily, not only convenient, saving of labor, save time, and avoided that each disassemble or assemble valve causes manually, material is as the waste of steel pad etc.And the present invention is little than existing safety check flow resistance, adopt the spool long service life of high interior mill material, noise is little.
Accompanying drawing explanation:
Accompanying drawing 1 the utility model sectional view
Reference character: 1, edge under valve body 2, valve pocket 3, valve seat 4, spool 5, valve rod 6, directed cavity 7, spring 8, water intake 9, directed cavity weep hole 10, valve gap 11, sealing gasket 12, bolt 13, outlet pipe 14, water outlet 15, outlet pipe tube chamber 16, the mistake 17,Guo mouth of a river, the mouth of a river.
Embodiment:
A kind of embodiment of easy maintenance fluid check valve as shown in Figure 1, comprise spool 4 on valve body 1, valve pocket 2, bottom valve seat 3, valve seat, with valve rod 5, stem guiding chamber 6, valve rod spring 7, the bottom water intake 8 of spool one.Valve body 1 one sides are provided with the outlet pipe 13 tilting with valve body, and the water outlet 14 of outlet pipe is the water outlet of this safety check, and it and valve body bottom water intake be not on same axis, and outlet pipe tube chamber 15 is connected with valve pocket 2 by the mistake mouth of a river 16 of valve pocket one side.Dismountable valve gap 10 is equipped with on valve body top, and the water outlet 14 of outlet pipe departs from valve gap 10, and valve gap is installed on valve body top by bolt 12, sealing gasket 11, during maintenance, only need open valve gap.The angle that outlet pipe and valve body tilt formation is α, and 35 °≤α≤50 °, present embodiment α=45 °.The valve pocket of present embodiment UNICOM outlet pipe cross the mouth of a river under it along 17 the thickness that highly equals spool 4.When spool rises, when the sealing surface with valve seat is left in its bottom surface, fluid can be crossed tank through spool periphery profile of tooth by water intake and enter valve pocket, discharges to outlet pipe through water outlet.When spool continue to rise, when exceeding valve pocket, crosses under the mouth of a river along 17 time its bottom surface, and fluid turns 45 ° of curved outlet pipes 13 that directly enter through water intake 8, through water outlet 14, discharges, and flow resistance is less.When valve rod 5 rises along directed cavity 6, the water in directed cavity is discharged in valve pocket 2 through the weep hole 9 of directed cavity wall.
The spool 3 of the utility model is by teflon, copper powder, graphite, diamantin, the agent of silicate gluing, through mixing, embryo processed, high temperature sintering, makes, and has high wear resistance, long service life.
