Description
Technical field
The present invention relates to a kind of star seal arrangement of diamond valve, be used for specifically the sealing configuration of diamond valve, belong to the diamond valve technical field.
Background technique
In sewage disposal technology, rhombus electric control valve operated by rotary motion is used for air quantity and regulates in the bio-oxidation pond air conduit.
The flow channel shape of diamond valve is rhombus, is that flange is connected with the Connecting format of pipeline.It mainly is comprised of valve body, valve plate, support, drive unit, seal ring and locating stud etc.Diamond valve is controlled the area of runner by moving up and down valve plate, thereby regulates ducted air mass flow.The patent No. is CN201010513587.8, and denomination of invention is: the patent of the modulating valve of sewage treatment aeration flow, and rubber o-ring is generally adopted in the sealing between its valve plate and the valve body, and its tightness is good, can realize sealing thoroughly.But because valve plate needs often to open and close, O shape circle needs larger precompression, and frictional force is larger, and seal ring and valve plate are in Frotteurism all the time, thereby have the shortcoming of poor durability.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, thereby a kind of star seal arrangement of diamond valve is provided, adopt the sealing of star seal ring, tightness is good, and pressure distribution is even, superior durability, guaranteed that diamond valve has superior tightness, and can prolong the working life of diamond valve.
According to technological scheme provided by the invention, the star seal arrangement of diamond valve comprises left valve barrel and right valve barrel, and left valve barrel and right valve barrel are bolted and are integral.Clamp valve plate between left valve barrel and the right valve barrel, it is characterized in that: be provided with left valve support chamber towards valve plate one side in the described left valve barrel, left seat ring is installed in the left valve support chamber, left seat ring one side is close to valve plate.On the left seat ring and valve plate joint is provided with the groove that holds the first star seal ring, and the first star seal ring in the groove is near valve plate.Be provided with right valve support chamber towards valve plate one side in the described right valve barrel, right seat ring is installed in the right valve support chamber, right seat ring one side is close to valve plate.On the right seat ring and valve plate joint is provided with the groove that holds the second star seal ring, and the second star seal ring in the groove is near valve plate.
Further, on the left seat ring and left valve barrel joint is provided with the first O-ring seals.
Further, on the right seat ring and right valve barrel joint is provided with the second O-ring seals.
Compared with the prior art the present invention has the following advantages:
Structure of the present invention is ingenious, compact, reasonable; Sectional shape is four sealing lips, does not produce distortion in groove, so can not roll in groove when to-and-fro motion; Adopt the sealing of star seal ring, dwindle than the precompressed of O type circle, frictional force is little; At the star ring cross-section preferably pressure distribution is arranged, thereby can obtain extraordinary sealing effect, guaranteed that diamond valve has superior tightness; Improved the working life of diamond valve; Between sealing lip, form lubricated cavity volume, improved the startup situation.
Description of drawings
Fig. 1 is structural representation of the present invention.
Description of reference numerals: 1-left valve barrel, 2-right valve barrel, 3-valve plate, 4-the first O-ring seals, the left seat ring of 5-, 6-the first star seal ring, 7-the second O-ring seals, the right seat ring of 8-, 9-the second star seal ring.
Embodiment
Following the present invention is further described in connection with the embodiment in the accompanying drawing:
As shown in Figure 1, the present invention mainly comprises left valve barrel 1 and right valve barrel 2, and left valve barrel 1 and right valve barrel 2 are bolted and are integral.Clamp valve plate 3 between left valve barrel 1 and the right valve barrel 2.
Be provided with left valve support chamber towards valve plate 3 one sides in the described left valve barrel 1, left seat ring 5 is installed in the left valve support chamber, left seat ring 5 one sides are close to valve plate 3.
On the described left seat ring 5 and left valve barrel 1 joint is provided with the first O-ring seals 4, by on the left seat ring 5 of the first O-ring seals 4 sealings and between the left valve barrel 1.
On the described left seat ring 5 and valve plate 3 joints are provided with the groove that holds the first star seal ring 6, and the first star seal ring 6 in the groove is near valve plate 3.
Be provided with right valve support chamber towards valve plate 3 one sides in the described right valve barrel 2, right seat ring 8 is installed in the right valve support chamber, right seat ring 8 one sides are close to valve plate 3.
On the described right seat ring 8 and right valve barrel 2 joints are provided with the second O-ring seals 7, between the second O-ring seals 7 right seat rings 8 of sealing and right valve barrel 2.
On the described right seat ring 8 and valve plate 3 joints are provided with the groove that holds the second star seal ring 9, and the second star seal ring 9 in the groove is near valve plate 3.
Described the first star seal ring 6 and the second star seal ring 9 adopt polytetrafluoroethylmaterial material to make.The first star seal ring 6 and the second star seal ring 9 rely on the elastic force of itself tightly to be pressed on the valve plate 3, thereby guarantee that diamond valve has good tightness.
Working principle of the present invention is: during the work of rhombus flow control valve, control the size of flow by the switching of valve plate 3.The first star seal ring 6 and the second star seal ring 9 rely on himself elastic force, tightly lean against on the valve plate 3.Because the first star seal ring 6 and the second star seal ring 9 sectional shapes are four sealing lips, do not produce distortion in groove, so can not roll in groove when to-and-fro motion.Frictional force is little, because it requires than the little precompression of O type circle.Less compression means less frictional force and wearing and tearing, thereby the long life-span is arranged.Sealing effect is very good, owing at the star seal ring preferably pressure distribution is arranged, thus can obtain extraordinary sealing effect.Between sealing lip, form lubricated cavity volume, improved the startup situation.
