Abstract
The utility model relates to a compressing seal water discharging valve, which is suitable for the sewer pipeline system of the toilet of the folk residential building, the office building, etc. The compressing seal water discharging valve is characterized in that a blowoff valve body is composed of a water inlet cavity and a water outlet cavity, between which a truncated conical through hole is arranged. A valve core assembly having a truncated conical rubber ring is arranged between the two cavities of the blowoff valve body; the truncated conical rubber ring is positioned on one side of the water inlet cavity; moreover, under the control of the both-end circular hole shaped guide rails, the truncated conical rubber ring can make the stable reciprocal motion. Thus, the compressing seal of the truncated conical rubber ring and the truncated conical through hole is realized; the compressing seal water discharging valve not only improves the reliability of the seal, radically solves the leakage problem of the water discharging valve, but also evidently lowers the noise.
Description
The utility model belongs to Draw off valve, is applicable in the lavatory drainage pipeline system of dwelling house among the people, office building, train and other communal facility.Be commonly called as stool water valve down.
Pressure handle formula and the foot-operated discharging valve that generally uses is standard component at present.Its structure has in " hot-water heating maintenance mans " book at length to be introduced.What this valve adopted is the mode of flat seal, and guide rail is short, easily crooked, thereby sealing performance is relatively poor, the run, drip, leak phenomenon happens occasionally, and has wasted water resource, produces bigger noise when opening/shutting valve, especially use night, noise is more obvious, brings worry to people.The turriform cushion rubber of this valve between turriform spring and metal handle, leakage easy to wear.Simultaneously because of its structure than complexity cost height.
The purpose of this utility model is exactly the water saving that designs in order to overcome the existing shortcoming of above-mentioned discharging valve, low noise, novel Draw off valve cheaply.
The compression seal discharging valve possesses all functions of the pressure handle formula discharging valve that generally uses at present, is the ideal novel product that existing discharging valve updates.
Major technique of the present utility model is characterised in that:
Intake antrum a and water chamber b are set on the valve body (1), are provided with truncated cone shape through hole C between two chambeies, the big mouth of through hole C is towards a chamber, and osculum is towards the b chamber, and there is water inlet a in a chamber

Above-mentioned relation is the essential condition (auspicious stating seen below) that realizes compression seal
Guide rail plug (16) is to have added a coaxial columnar guide pin bushing in the centre of common plug, and the downside of guide pin bushing has overflow aperture 1-6.
The compression seal discharging valve promptly is the intake antrum a at valve body (1), be provided with between truncated cone shape through hole C, the water chamber b can be reciprocating core assembly be with back-up ring (4) on the spool (7), and truncated cone cushion rubber (3) and by flat nut (2) fastening it.Truncated cone cushion rubber (3) is between intake antrum a and truncated cone shape through hole C.The seeker d of spool (7)
1And thin guide rod d
2In guide rail plug (16) is aimed at and inserted to part the outer cylindrical shape guide pin bushing that is with spring (14), vulcan fibre pad (15) is fastened on the screw thread port a of valve body (1) with guide rail plug (16)
2The place.The thick guide rod d of spool (7)
4Part is passed through water chamber b through guide rail hole b

3In and pressure cap is anchored on internal thread port b
4The place.Be equipped with cap (8) handle (9) is fastened on port b
4The outside.Hexagonal (hexagon)nut (11) is fastened on rubber gasket (12), union (13) the water inlet a of valve body (1)
1The outside.
Intact compression seal discharging valve is installed, hexagonal (hexagon)nut (11), rubber gasket (12), the water inlet a of union (13) and valve body (1)
1, delivery port b
1On same axis m; Guide rail plug (16), is equipped with the port a of cap (8) and valve body (1) at vulcan fibre pad (15), spring (14), flat nut (2), truncated cone cushion rubber (3), back-up ring (4), O-ring seals (5), back-up ring (6), pressure cap (10), spool (7), handle (9)
2, truncated cone shape through hole C, guide rail hole b
2, seal groove b

4On same axis n.
When pressing fixed handle (9), lever force is at guide rail mechanism ［ the guide rail hole b of valve body (1)
2Form axial guidance with the guide pin bushing of guide rail plug (16) for core assembly ］ control under, promote core assembly and steadily move to a cavity direction, truncated cone cushion rubber (3) breaks away from the truncated cone shape through hole C of valve body (1), spring this moment (14) compression, current are unimpeded; When release handle (9), spring (14) promotes core assembly to b chamber return, because e

2So the contact wire of a circle appearred in the corresponding lonely face of the truncated cone shape through hole C of the little external diameter edge of truncated cone cushion rubber (3) and valve body (1) before this, this moment, current ended, and then core assembly has been subjected to the effect of the water pressure more much bigger than spring force again, truncated cone cushion rubber (3) continues to move, but be subjected to again simultaneously valve body (1) truncated cone shape through hole C corresponding lonely face obstruction and present compressive strain, circular contact wire has become the contact surface of truncated cone shape.When water pressure and spring force sum equaled the compressive strain power of truncated cone cushion rubber, the motion of core assembly stopped.The compressive strain of truncated cone cushion rubber has not only improved the reliability of sealing, and the kinergety of the core assembly of having eaten, and has reduced vibration, has reduced noise, this principle appellation " truncated cone cushion rubber compression seal "
The mode of O-ring seals has been adopted in the sealing of water chamber b, has replaced the sealing means of the turriform cushion rubber of existing discharging valve, so simple and easy to do.
The utility model can become foot-operated control mode with the pressure handle formula as required.
The new principle of " truncated cone cushion rubber compression seal " can be widely used in the design and the manufacturing that require valve in the high especially poisonous pipe-line system of sealing performance.
Major advantage of the present utility model is: water saving, low noise, low cost.
