Abstract
A spherical cone new bottom valve which can be applied with a pump and is provided with a valve core of guiding rode type, comprises a hoist, a buckle, and a valve sore, and the connection of the hoist and the buckle is provided in a radial way with a valve separator with a via hole in the middle, and the valve core is constituted of a valve core body matching with the valve separator via hole and the guide bar thereof, and they are a whole part. The guide seat hole of the guide bar is arranged on the top of the hoist. A sealed wall member is arranged between the peripheral upper edge of the via hole of the valve separator and the valve core body to form a sealed surface, and the valve core body toward the buckle appear in a spherical cone shape and penetrates the round via hole of the valve separator to drop in the buckle cavity. In concrete application, the guide bar is hollow and appears in tubular shape, and the hollow cavity is embedded with a round steel guide bar core. After designing the valve core bottom into an arc external convexity shape, the utility model not only further improves the sealing performance of the sealed surface, but also strengthens the guide location effect. In addition, when the present guide bar is made of non metallic material, the guide location effect will be better after providing a weighted guide bat core in the guide bar.
Description
Affiliated technical field
The utility model belongs to a kind of valve, relates in particular to a kind of bottom valve that mates use with water pump and have guiding rod-type spool.
Background technique
Before the utility model was made, bottom valve had polytype, and for example: flange-type, faucet type etc., its spool generally adopt guiding rod-type or traditional leaf structure, relied on water pump fortune to stop the alternate control spool of inhaling pressure that produces during use and opened and closed.The structure of guiding rod-type bottom valve comprises the filtered water cover (being commonly called as Hua Lan) of superposed valve gap (being commonly called as cucurbit) and bottom, and place cucurbit and the spool of spending indigo plant to close in the chamber to constitute, connection level place at cucurbit, Hua Lan radially is provided with the valve curtain that a middle part has through hole, spool is made of the valve core and the guide rod thereof that are complementary with the valve curtain through hole, the guide holder hole of guide rod is located at the cucurbit top center, and there is seal spool steering capability defective relatively poor, that easily leak and be out of shape in this valve when practical application.
Summary of the invention
Relatively poor for overcoming existing guiding rod-type bottom valve sealability, easily leak, spool is yielding, the deficiency of attachment portion easy-rupturing, and the utility model provides that a kind of architecture is simple, good seal performance, ball taper novel bottom valve that reliability is high.
Its technological scheme is: comprise this bottom valve that cucurbit, Hua Lan, spool constitute, radially be provided with the valve curtain that a middle part has through hole in the joint of cucurbit, Hua Lan, spool is made up of the valve core and the guide rod thereof that are complementary with the valve curtain through hole, they are single piece, the guide holder hole of guide rod is located at the cucurbit top, its main points are: valve core top and valve curtain bore periphery upper limb coupling have a sealing shirt rim, form sealing surface, the curved outer gibbosity of one side towards the valve core of gaily decorated basket direction, and pass the manhole of valve curtain, drop in the gaily decorated basket chamber.
Above-mentioned arc outer gibbosity is the ball taper.
During concrete enforcement, guide rod hollow is equipped with in the chamber of hollow and increases the weight of bar in a tubular form.
Beneficial effect is: after the spool bottom is designed to the arc outer gibbosity, both further improved the sealability of sealing surface, and strengthened the guide-localization effect again.Existing in addition guide rod material is generally made by nonmetallic material, the utility model in the chamber of guide rod hollow, insert one increase the weight of bar after the guide-localization effect better.
Description of drawings
Fig. 1 is to be the vertical profile structural representation of example with the flange-type bottom valve for the utility model, the end flange that draws on figure.
Embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.
Referring to Fig. 1.Sequence number is represented respectively among the figure: water pump takes over 1, cucurbit interface 2, cucurbit chamber 3, cucurbit sidewall 4, cucurbit shirt rim 5, screw 6, valve curtain 7, the gaily decorated basket 8, grid hole 9, valve core 10, sealing shirt rim 11, guide rod 12, guide rod core 13.
Referring to Fig. 1.Circular and centre has the valve curtain 7 of manhole, and its outer has some through holes, will be tightened together as the cucurbit of last shell and the indigo plant 8 of spending of lower casing by the screw 6 of bolt on cucurbit shirt rim 5.Spool is made up of the valve core 10 and the guide rod 12 thereof that are complementary with valve curtain 7 manholes, and they are one-piece element, are made by vulcanite.The sealing shirt rim 11 of close core body 10 and the peripheral upper limb coupling of the manhole of valve curtain 7, sealing shirt rim 11 forms sealing surface with the manhole upper edge of valve curtain 7, and the sealing face is provided with corresponding sealed groove and " o " shape seal ring thereof.Valve curtain 7 adopts the valve core of ball taper towards the curved outer gibbosity of one side of the valve core 10 of the gaily decorated basket 8 directions, and passes the manhole of valve curtain 7, drops in the gaily decorated basket 8 chambeies.In the present embodiment, guide rod 12 hollows, the chamber is built-in with that to increase the weight of bar be guide rod core 13, and guide rod core 13 is a solid round steel, plays the effect of stablizing center of gravity.
Cucurbit sidewall 4 middle parts that are positioned at valve curtain 7 tops form cucurbit chamber 3 (this sidewall is curved), and it is equipped with cucurbit shirt rim 5 in square opening edge down; The top is equipped with cucurbit interface 2, adopts screw thread to spin with flange, can certainly adopt the fastening method of screw.Cucurbit interface 2 indents at middle part and water pump are taken over 1 screw thread and are spun.The guide rod 12 of spool places in the cucurbit chamber 3, vertically puts, and its guide holder hole is located at the center at cucurbit top, and it is whole that guide holder hole and cucurbit top are, and the guide holder hole is linked to be integral body with cross posture and cucurbit choma wall, and the cross gap is an osculum.
The gaily decorated basket 8 places valve curtain 7 belows, and its bottom and ring wall are provided with grid hole 9, are used to into water.
