Abstract
The utility model relates to a punching feed valve for a water transmission pipe, which comprises a valve body, a connecting rod valve plate, a valve rod, an upper cover and a pressure rod nut; wherein the upper opening of the valve body is connected with an upper cover and its lower opening is connected with an upper hoop, the connecting rod valve plate movably matched with the inner hole of the upper cover is connected with the valve rod through a thread, the valve rod is axially fixed, and a sealing ring is arranged between the valve rod and the upper cover, which makes the whole feed valve sealing, dustproof and leakage-proof.
Description
Technical field the utility model relates to conduit pipe boring hole with water field, is applicable to a kind of boring hole with water feed valve that arm is installed on the water pipe.
The valve rod of the boring hole with water feed valve in the existing production and supply market of background technique is that axially turnover is moved, and dirt enters in the valve easily, brings in running water pipe the water quality vulnerable to pollution into.Another defective is that valve plate is connected with valve rod is the sphere bascule, its perpendicularity instability, and it is many to close the water valve water leakage phenomenon, waste water resource.Former besides feed valve is because the sealing material that self structure adopts is asbestos yarn or asbestos rope, poor sealing performance, and the life-span is short.
Summary of the invention goal of the invention of the present utility model is in order to improve feed-water quality, and especially the quality of potable water reduces the pollution that feed valve itself causes to potable water, to this, has designed the good boring hole with water feed valve of a kind of sealing structure performance.
The technological scheme of the utility model design mainly includes upper and lower hoop, valve body, the link rod valve plate, valve rod loam cake and depression bar nut, last hoop is communicated with the valve body end opening, valve body connection loam cake suitable for reading end opening, the loam cake depression bar nut that is threaded suitable for reading, the crimping valve rod, the structural feature of this feed valve is a loam cake endoporus socket link rod valve plate, valve rod is threaded with the link rod valve plate, and valve rod is equipped with seal ring with the loam cake joint.
The blind rod type structure that the utility model design adopts valve rod to be threaded with the link rod valve plate, stem shaft is to stationary positioned, prevent that dirt from entering in the valve, the loam cake endoporus with link rod valve plate gap movingly, guarantee perpendicularity, be equipped with the two seals circle at valve rod and loam cake joint in addition, improved sealability, prevent to leak.
Drawing explanatory drawing 1 is the utility model topology view.
1-depression bar nut, 2-hoop is used sealing gasket, 3-valve rod, 4-seal ring, 5-loam cake, 6-valve seal pad, 7-link rod valve plate, 8-valve body, 9-go up and bind round, 10-down hoops.
The loam cake 5 that is threaded suitable for reading of embodiment the utility model valve body 8 upper ends, connection mouth is put and is lined with valve seal pad 6, loam cake 5 hexagonal endoporus cooperate with the hexagonal cylinder link rod valve plate 7 that valve rod 3 is threaded, and left and right rotary valve rod 3 can make the link rod valve plate along upper and lower the moving axially of loam cake 5 hexagon rings.One of link rod valve plate 7 lower end are tapered, are sealed and matched with valve body 8 end openings.The loam cake 5 depression bar nuts 1 that are threaded suitable for reading with loam cake a 5-location valve rod 3, are provided with two seal rings 4 at loam cake 5 with the valve rod 3 activity places of being connected; Valve body 8 lower end end openings are threaded, and to go up hoop 9 suitable for reading, on bind round 9 with bind round 10 down and be connected by bolt, consult Fig. 1.Whole feed valve is fastened on following hoop 10 by last hoop 9 to be needed on the water pipe of the attaching by-pass line position, cambered surface is close to hoop seal ring 2 in the middle of last hoop 9 outers suitable for reading, anti-water stopping tube perforate mouth leaks, at valve body 8 loam cake 5 parts that unload suitable for reading, load onto drilling device, give the water outlet dress envelope annex on valve body 8 right sides, after water pipe punching completion, lay down drilling device, loam cake 5 parts are loaded onto in the limit on the left position of annex precession simultaneously valve body 8, get except that behind the annex, a left side, dextrorotation ovable valve stem 3 drives link rod valve plate 7 upper and lower moving axially and opens or closes valve body 8 end openings.
