Abstract
The invention discloses an easy-maintenance check valve for fluid, and relates to valves. The easy-maintenance check valve comprises a valve, a valve seat, a valve spool, a valve stem, a guide cavity, a spring, a water inlet and a water outlet, and is characterized in that a water outlet tube which is inclined relative to the valve is arranged on one side of the valve, the water outlet of the water outlet tube and the water inlet at the bottom of the valve are not positioned on the same axis, a tube cavity of the water outlet tube is communicated with a valve cavity via a water flowing port of the valve cavity, the water flowing port of the valve cavity is arranged on one side of the valve cavity, and a detachable valve bonnet is arranged on the top of the valve. Teflon, copper powder, graphite, corundum powder and silicate adhesive are mixed and manufactured into a blank, and the blank is sintered at a high temperature to form the valve spool. The easy-maintenance check valve has the advantages that only the valve bonnet on the top of the valve needs to be opened without detaching the integral easy-maintenance check valve from a pipeline when the easy-maintenance check valve is maintained, the easy-maintenance check valve can be conveniently maintained by one person, and is convenient, labor-saving and time-saving, and wastage of labor and materials such as steel cushions in each valve assembly and disassembly procedure is prevented; and compared with an existing check valve, the easy-maintenance check valve is low in flow resistance, and the valve spool made of materials with high abrasion resistance is long in service life.
Description
Technical field:
The present invention relates to valve, relate generally to the fluid one-way valve, particularly fluid check valve.
Background technique:
Be installed on the particularly safety check on the mesohigh pipeline of fluid line, mostly be Through-conduit check valve greatly, be connected on the pipeline by flange, when valve damages, particularly spool, spring etc. damage when needing to change, then whole safety check need be unloaded down from pipeline and be carried out maintain and replace, and then be installed on the deferent.And charge and discharge valve often needs two or three people to finish from the pipeline, very difficult, trouble.Moreover the flow resistance of existing safety check is bigger, and spool is not wear-resisting, and working life is short, and noise is big.
Summary of the invention:
The present invention's purpose, be to unload the problem of overhauling difficulty and the defective that existing safety check flow resistance is big, the spool life-span is short from integral body on the pipeline at 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 the foregoing invention purpose is, a kind of easy maintenance fluid check valve, comprise spool 4 on valve body 1, valve pocket 2, bottom valve seat 3, the 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 that tilts with valve body, the water outlet of outlet pipe and valve body bottom water intake be not on same axis, and outlet pipe tube chamber 15 links with valve pocket 2 by the mistake mouth of a river 16 of valve pocket one side.The 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 °.
Technique scheme further preferably, described spool 3 is by teflon, copper powder, graphite, diamantin, the agent of silicate gluing, makes through mixing, embryo processed, high temperature sintering.
The beneficial effect that the present invention produces is:
In the outlet pipe that valve body one side setting and valve body tilt, the water outlet of outlet pipe and valve body bottom water intake be not on same axis, and the outlet pipe tube chamber links by the mistake mouth of a river and the valve pocket of valve pocket one side, and the valve body top is provided with dismountable valve gap.When needs maintenance valve is, will not unload from pipeline by whole valve, get final product 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, the waste of material such as steel pad etc.And the present invention is little than existing safety check flow resistance, adopts the spool long service life of high interior mill material, and noise is little.
Description of drawings:
Accompanying drawing 1 sectional view of the present invention
Reference character: 1, 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 mouth of a river 17, mistake lower edge, 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, the 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 that tilts 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 links 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 the valve body top, and the water outlet 14 of outlet pipe departs from valve gap 10, and valve gap is installed on the valve body top by bolt 12, sealing gasket 11, only need open valve gap during maintenance and get final product.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 is crossed the thickness that highly equals spool 4 of its lower edge 17, the mouth of a river.When spool rises, when sealing surface with valve seat was left in its bottom surface, fluid can be crossed tank through spool periphery profile of tooth by water intake and enter valve pocket, discharged through water outlet to outlet pipe.When spool continue to rise, when its bottom surface exceeded valve pocket and crosses lower edge 17, the mouth of a river, fluid then turned 45 ° of curved outlet pipes 13 that directly enter through water intake 8, discharges through water outlet 14, and flow resistance is less.When valve rod 5 rose along directed cavity 6, the water in the directed cavity was discharged in the valve pocket 2 through the weep hole 9 of directed cavity wall.
The present invention's spool 3 is by teflon, copper powder, graphite, diamantin, the agent of silicate gluing, makes through mixing, embryo processed, high temperature sintering, has high wear resistance, long service life.
