Abstract
The invention relates to a high-abrasion-resistance sealing device for a rhombus valve. According to the high-abrasion-resistance sealing device, a valve base ring is embedded between a valve plate and a valve body; a sealing ring is fixed between the valve base ring and the valve plate; an O-shaped sealing ring is embedded between the valve base ring and the valve body; an elastic rubber ring is located between the valve base ring and the sealing ring; one end of the elastic rubber ring is butted against the valve base ring while the other end is embedded in a groove of the sealing ring; and the elastic rubber ring is under a compressed state and tightly presses the sealing ring on the valve plate, so that the excellent air tightness of the rhombus valve is ensured. According to the high-abrasion-resistance sealing device, polytetrafluoroethylene is taken as the material of the sealing ring, so that the sealing device has excellent abrasion resistance and the service life of the rhombus valve is prolonged; the elastic rubber ring is tightly attached to the valve plate, so that the defect of insufficient air tightness of the polytetrafluoroethylene is overcome; and the O-shaped sealing ring is arranged between the valve base ring and the valve body, so that the excellent air tightness of the rhombus valve is further ensured by the double sealing.
Description
Technical field
The present invention relates to a kind of seal arrangement of high wear resistance, specifically it is a kind of high wear resistance seal arrangement 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 high wear resistance seal arrangement 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 high wear resistance seal arrangement of rhombus valve comprises left valve barrel, right valve barrel, valve plate, and said valve plate is clipped between left valve barrel and the right valve barrel, and left valve barrel and right valve barrel connect through bolton; Embedded seat ring between said valve plate and the valve body; Be fixed with seal ring between seat ring and the valve plate; O-ring seals in embedding between seat ring and the valve body; Said elastic caoutchouc circle is between seat ring and seal ring; Said elastic caoutchouc circle one end heads on seat ring, and the other end embeds in the groove of seal ring, and the elastic caoutchouc circle is in compressive state; 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 and elastic caoutchouc circle adopt the fluorine rubber material to process respectively.
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 the elastic caoutchouc circle 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 high wear resistance seal arrangement of rhombus valve comprises valve body 1 (left valve barrel 1a, right valve barrel 1b), valve plate 2, O-ring seals 3, seat ring 4, elastic caoutchouc circle 5 and seal ring 6.Said valve plate 2 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.Embedded seat ring 4 between said valve plate 2 and the valve body 1.Be fixed with seal ring 6 between seat ring 4 and the valve plate 2.O-ring seals 3 in embedding between seat ring 4 and the valve body 1.Said elastic caoutchouc circle 5 is between seat ring 4 and seal ring 6; One end heads on seat ring 4; One end embeds in the groove of seal ring 6; Elastic caoutchouc circle 5 is in compressive state, thereby relies on the elastic force of itself that seal ring 6 tightly is pressed on the valve plate 2, thereby guarantees 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 elastic caoutchouc circle 5, 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 seal arrangement.And at opposite side, between seat ring 4 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 seal arrangement sealability.The high wear resistance seal arrangement of rhombus valve of the present invention has obtained superior sealability and permanent working life simultaneously.
