Abstract
The invention relates to a seal structure of a diamond valve, comprising a left valve body, a right valve body, a disc. The said disc is clamped between the left valve body and the right valve body, and the left valve body is fixedly connected with the right valve body by a bolt; a valve seat inert is embedded between the disc and the valve body, a seal ring is embedded between the valve seat insert and the disc, and an O-shaped seal ring is embedded between the valve seat insert and the valve body; one end of the said cylindrically coiled compression spring is against the valve body, and the other end is against the valve seat insert. The seal ring is pressed tightly on the disc, thus good air-tightness of the diamond valve is guaranteed. According to the invention, polytetrafluoroethylene is adopted as the material of the seal ring, so that the seal devise has good abrasion resistance, and the service life of the diamond valve is lengthened. The compression spring is adopted which the seal ring is stuck tightly to the disc, and the disadvantage of the insufficient air-tightness of polytetrafluoroethylene is overcome; the o-shaped seal ring is adopted between the valve seat insert and the disc, so that such double seals further guarantee that the diamond valve has superior air-tightness.
Description
Technical field
The present invention relates to a kind of sealing configuration of valve, specifically it is a kind of seal en-hancement structure that is applied to the rhombus valve.
Background technique
The rhombus electric control valve is generally done air quantity and is regulated use in sewage treatment process bio-oxidation pond air conduit.The flow channel shape of rhombus valve is a rhombus, is that flange is connected with the Connecting format of pipeline.It mainly is made up of valve body, valve plate, support, drive unit, seal ring and locating stud etc.The rhombus valve is controlled the area of runner through moving up and down valve plate, thereby regulates ducted air mass flow.The ZL patent No. is 201010513587.8, and denomination of invention is that rubber o-ring is generally adopted in the sealing between valve plate and the valve body in the sealing configuration of modulating valve of aeration in sewage treatment flow, and tightness is good like this, can realize sealing completely.But because valve plate needs often to open and close, seal ring and valve plate are in Frotteurism all the time, and rubber material wears no resistance, thereby has the shortcoming of poor durability.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, thereby a kind of sealing configuration of rhombus valve is provided, the sealing structure adopts double seal; Its tightness is good; Superior durability has been guaranteed that the rhombus valve has superior tightness, and can have been prolonged the working life of rhombus valve.
According to technological scheme provided by the invention; A kind of sealing configuration of rhombus valve comprises valve body, valve plate; Characteristic is: be embedded with seat ring between said valve plate and the valve body, be embedded with seal ring between said seat ring and the valve plate, be embedded with O-ring seals between said seat ring and the valve body; Said cylindroid helicalcoil compression spring one end heads on valve body, and the other end heads on seat ring, seal ring tightly is pressed on the valve plate, thereby guarantees that the rhombus valve has good air-tightness.
As further improvement of the present invention, said seal ring adopts polytetrafluoroethylmaterial material to process.
As further improvement of the present invention, said O-ring seals adopts the fluorine rubber material to process.
Compared with present technology the present invention has the following advantages:
Owing to adopt teflon as sealing ring material, make seal arrangement have good wear resistance, prolonged the working life of rhombus valve.Adopt pressure spring again, seal ring tightly is attached on the valve plate, overcome the not enough shortcoming of teflon tightness.And between seat ring and valve body, adopt the O RunddichtringO, such double seal has guaranteed that especially the rhombus valve has superior tightness.
Description of drawings
Fig. 1 is the user mode figure of structure of the present invention.
Embodiment
Following the present invention will combine the embodiment in the accompanying drawing to further describe:
As shown in Figure 1: a kind of improvement structure of rhombus valve seal comprises valve body 1 (left valve barrel 1a, right valve barrel 1b), valve plate 2, O-ring seals 3, cylindroid helicalcoil compression spring 4, seat ring 5 and seal ring 6.Said valve plate 3 is clipped between left valve barrel 1a and the right valve barrel 1b, and left valve barrel 1a and right valve barrel 1b connect through bolton.Also embedded seat ring 5 between valve plate 2 and the valve body 1.Seal ring 6 in embedding between seat ring 5 and the valve plate 2.The material of said seal ring 6 is a teflon.O-ring seals 3 in embedding between seat ring 5 and the valve body 1.The material of said O-ring seals 3 is a fluorine rubber.Said cylindroid helicalcoil compression spring 4 one ends head on valve body 1, one end and head on seat ring 5, thereby seal ring 6 tightly is pressed on the valve plate, thereby guarantee that the rhombus valve has good air-tightness.
During the work of rhombus flow control valve, come the size of control flow rate through the switching of valve plate 2.Seal ring 6 receives the pressure of cylindroid helicalcoil compression spring 4, tightly leans against on the valve plate 2, has guaranteed good sealing effect.The antiwear characteristic that polytetrafluoroethylmaterial material itself is good has been guaranteed the working life of this sealing configuration.And at opposite side, between seat ring 5 and the valve body 1, the O-ring seals 3 of fluorine rubber as material used in two relatively-stationary positions, more guaranteed the superiority of this sealing configuration sealability.The improvement structure of rhombus valve seal of the present invention has obtained superior sealability and permanent working life simultaneously.
