Abstract
The utility model discloses a strengthening seal non-leakage valve, belonging to the valve field, which comprises a water inlet shoot valve body, a water outlet shoot valve body, a valve stem, a handle, a gland bush and a sealing ring; wherein, the valve stem plugs into the valve body; the handle is connected with the valve cap by thread; the handle is connected with the valve stem by a snap spring and is slide fitted with the valve stem; the sealing ring is arranged in the thread connection joint of the valve cap and the valve body; a groove is arranged in the inner side of the valve cap; the O shape sealing ring is arranged between the groove of the valve cap and the central section of the valve stem. The utility model is characterized in that a spool cut-off body which is composed of a bottom plate, a seal washer of bottom plate, and a lower platen is arranged on the lower part of the valve stem and is fixed by bolt; a gate sealing ring is arranged in the gate of the lower part of the valve body. The utility model has the advantages that the pressure inside the shoot makes the gate sealing ring and the spool press tightly, as the valve is closed and the valve stem is completely raised; the higher the water pressure is, the better the feature of sealing is; and the other advantages of non-leakage and long service life.
Description
Technical field
The utility model relates to the valve field of carrying in the liquid line.
Background technique
Will use the valve of a large amount of various sizes in carrying the pipeline of liquid, existing valve exists mostly that medium lets out and screw thread contacts with medium and is subjected to etching problem from spool.Particularly some valves are because Sealing sealing effect own is bad, and valve leakage easy to wear damages, and working life is short.
Summary of the invention
The purpose of this utility model is the shortcomings and deficiencies that overcome conventional valves, provides a kind of simple in structure, good seal performance, and long service life is applicable to the novel enhanced leaktightness leakage-free valve of large-scale high pressure valve.
The utility model is to realize like this, it includes the valve body of a water intake runner and a water outlet runner, valve rod, handle, gland and seal ring etc., valve rod inserts in the valve body, handle and valve gap are by being threaded, handle is connected by jump ring with valve rod, and be slidingly matched, be provided with seal ring at valve gap and valve body threaded connection place, have a groove in the inboard of valve gap, the O RunddichtringO be located in the groove of valve gap and the valve rod middle part between, it is characterized in that being provided with by bottom plate in stem lower portion, the spool that bottom plate seal washer and press table constitute ends body, and by bolt, is provided with the sluice gate seal ring at the sluice gate place of valve body lower portion.
The valve of this structure, when valve was in the closed condition valve rod and lifts fully, the pressure in the runner compressed sluice gate seal ring and spool, and hydraulic pressure is big more, and sealing effect is good more, and valve can never leak, and has prolonged the working life of valve effectively.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to accompanying drawing 1, the utility model includes the valve body 7 of a water intake runner and a water outlet runner, valve rod 4, handle 2, gland 3 and seal ring etc., valve rod 4 inserts in the valve body 7, handle 2 and valve gap 3 are by being threaded, handle 1 is connected by jump ring 1 with valve rod 4, and be slidingly matched, be provided with seal ring 6 in valve gap 3 and valve body 7 threaded connection places, have a groove in the inboard of valve gap 3, O RunddichtringO 5 is located in the groove of valve gap 3 and between valve rod 4 middle parts, it is characterized in that being provided with by bottom plate 11 in valve rod 4 bottoms, the spool that bottom plate seal washer 10 and press table 9 constitute ends body, and fixing by bolt 12, the purpose that bottom plate 11 and press table 9 are provided with is, when valve rod moves up and down, prevent that the Sealing that spool ends body under high pressure is out of shape, and prolongs the working life of valve.Sluice gate place in valve body lower portion is provided with sluice gate seal ring 8.When valve was in closed condition valve rod 4 and lifts fully, the pressure in the runner compressed sluice gate seal ring 8 and spool, and hydraulic pressure is big more, and sealing effect is good more.
Main points of the present utility model also are to have a groove 13 on described bottom plate 11, also open a groove 14 on press table 9.Its objective is that bottom plate 11 and press table 9 for making spool end body can be combined into one securely with bottom plate seal washer 10 threes, and connection part there is not the gap.
This is reasonable with new structure, and is easy to maintenance, more is applicable to large-scale high pressure valve.
Claims (3)
1, a kind of novel enhanced leaktightness leakage-free valve, include the valve body of a water intake runner and a water outlet runner, valve rod, handle, gland and seal ring etc., valve rod inserts in the valve body, handle and valve gap are by being threaded, handle is connected by jump ring with valve rod, and be slidingly matched, be provided with seal ring at valve gap and valve body threaded connection place, have a groove in the inboard of valve gap, the O RunddichtringO be located in the groove of valve gap and the valve rod middle part between, it is characterized in that being provided with by bottom plate (11) in valve rod (4) bottom, the spool that bottom plate seal washer (10) and press table (9) constitute ends body, and fixing by bolt (12), is provided with sluice gate seal ring (8) at the sluice gate place of valve body lower portion.
