Abstract
A long-life non-leakage stop valve is composed of valve body, valve sleeve, check ring, valve core, valve cover and valve rod. The valve core is made of rubber or polytetrafluoroethylene elastic materials, and is suitable for intercepting and conveying cold water, hot water, steam, coal gas, natural gas, organic fluid, inorganic fluid, various liquids and other media. The valve core is arranged in the valve body, and the valve rod controls the extension of the valve core through a check ring at the lower top end of the valve rod, so that the flow interception and the flow control are realized. Because of the sealing of the telescopic valve core, the valve rod is not contacted with the medium, so the medium leakage is avoided, and the rotating point of the valve rod can be applied with lubricant, so the use is labor-saving and convenient.
Description
The utility model relates to pipeline valve, and relating in particular to does not have the long-lived stop valve of leakage.
Commercially available pipe break valve, its sealing configuration be in valve gap and the joining asbestos rope of valve rod chamber around asbestos rope, compress with loam cake again.Owing to often screwing wearing and tearing, the gap between asbestos rope and valve rod increases, and the flowing medium with certain pressure makes and can bore seam and go out formation run, drip, leak phenomenon.Valve rod directly is immersed in the medium, can not add oiling agent, causes to screw painstakingly, and heavy caliber is by particularly outstanding.
The purpose of this utility model is, fundamentally solves the run, drip, leak phenomenon of stop valve, provides a kind of nothing that valve rod is not contacted with the line transportation medium to leak the long-lived valve that ends.
Task of the present utility model realizes in the following manner: at the rubber of stem lower portion suit of stop valve or the scalable spool of latex class material.The upper end of spool is a circular opening, and lower end closed is pressed on above the valve body with the top circular opening of valve gap with spool.Open valve, medium is isolated by spool, can only flow through in the valve body chamber.Be screwed down valve rod, valve rod is descending under the effect of spiral, promotes scalable spool by the Steel Cable Baffle Ring of valve rod next top and blocks valve pocket, throttle down.Upwards unscrew valve rod, valve rod is then up under the effect of spiral, and drives scalable spool contraction by the Steel Cable Baffle Ring of valve rod next top, with valve open.
Nothing described in the utility model is leaked long-lived stop valve, and good airproof performance is simple in structure.Because valve rod does not contact with medium, can not occur the run, drip, leak phenomenon again.Valve gap and valve body fasten with the upper end circular opening of screw with spool, can save the asbestos rope chamber, tight platform of six side's plates and following helical thread portion.Nothing described in the utility model is leaked long-lived stop valve.The rotation position oiling agent of can annotating.Because the good airproof performance of spool, oiling agent can not drain in the medium and go.Therefore, adopt the heavy caliber stop valve of the technical solution of the utility model, it is obviously laborsaving that operation can become, and cost and maintenance cost all can reduce greatly.Nothing described in the utility model is leaked long-lived stop valve and be can be used for cold water, hot water, steam, rock gas, organic fluid, inorganic matter fluid, the conveying of various liquid and other medium.
Accompanying drawing is the schematic representation that meets the utility model theme.
1-valve body 2-valve pocket 3-back-up ring 4-spool 5-valve gap 6-screw
7-handwheel 8-valve rod 9-nut
Referring now to accompanying drawing, be described as follows in conjunction with the embodiments:
According to the composition of the medium that will carry, valve body (1) and spool (4) should be selected suitable material for use.Such as, carry cold water, the available plain cast iron spare of valve body (1), spool (4) can be selected General Purpose Rubber class material for use.If delivering hot water or steam, spool (4) should be selected resistant to elevated temperatures elastic material for use, as polytetrafluoroethylene etc.Spool (4) is placed in the valve body (1), compresses with valve gap (5) above.The bottom of spool (4) gets lodged on valve pocket (2) mouth that medium enters.The upper end of spool (4) is placed between valve body (1) and the valve gap (5), fastening with screw (6).Handwheel (7) is fastened on the top of valve rod (8), and valve rod (8) and valve gap (5) be for for being threaded, can spinning in and out, and be used for lifting or press down the Steel Cable Baffle Ring (3) of valve rod (8) bottom.Insert in the interior circular groove of scalable spool (4) bottom of valve rod (8), with Steel Cable Baffle Ring (3) chucking.During turn handwheel (7), scalable spool (4) is under the drive of valve rod (8), and is flexible up and down, thereby prevented that scalable spool (4) from damaging with rotation.Control the flexible up and down of scalable spool (4), can realize the keying and the Flow-rate adjustment of valve.Control piece does not contact with medium, can reach the purpose that medium does not leak.Handwheel (7) can be made umbrella, and not only beautiful shape can prevent that also the external world from coming the immersion of water or rainwater, causes the corrosion of valve rod (8), spool (4) and valve gap (5).The regular drip-feed lubricating agent of helical thread portion in that valve gap (5) is connected with valve rod (8) can keep not corrosion of valve rod (8), and rotation is convenient.
Claims (3)
1, a kind of nothing is leaked long-lived stop valve, include valve body, valve pocket, back-up ring, spool, valve gap composition, described spool adopts rubber-like elastic material to make, under the effect of valve gap spiral, realize lifting by valve rod, the keying of control valve and rate-of flow, it is characterized in that described spool is placed in the valve body, the upper open end of spool is pressed between valve body and the valve gap.
2, nothing according to claim 1 is leaked long-lived stop valve, it is characterized in that the lower end of valve rod is connected with the flexible back-up ring of control spool.
3, nothing according to claim 1 is leaked long-lived stop valve, it is characterized in that the upper end of described valve rod is provided with the handwheel of umbrella.
