According to the L-shaped sealing device of the diamond valve, which is disclosed by the utility model, the sealing structure utilizes an L-shaped sealing ring, so that the air tightness is good, the pressure is distributed uniformly, the durability is excellent, the excellent air tightness of the diamond valve is ensured, and the service life of the diamond valve can be prolonged.
Description
Technical field
The utility model relates to a kind of L shaped seal arrangement that is applied to diamond valve, belongs to mechanical structure technical field.
background technique
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 diamond valve is rhombus, is that flange is connected with the Connecting format of pipeline.It is mainly 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 ZL patent No. is 201010513587.8, and the sealing in the sealing configuration of the modulating valve that denomination of invention is sewage treatment aeration flow between valve plate and valve body generally adopts rubber o-ring, and tightness is good like this, 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, seal ring and valve plate be all the time in Frotteurism, of long duration after, O shape is enclosed serious wear, thereby affects tightness, has the shortcoming of poor durability.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thereby provide a kind of L shaped seal arrangement of diamond valve, sealing structure adopts L shaped seal ring, its tightness is good, pressure distribution is even, superior durability, has guaranteed that diamond valve has superior tightness, and can extend the working life of diamond valve.
The technological scheme providing according to the utility model: a kind of L shaped seal arrangement of diamond valve comprises left valve barrel, right valve barrel, valve plate; Described valve plate is clipped between left valve barrel and right valve barrel, and left valve barrel and right valve barrel connect by bolton; Feature is: also comprise the first O-ring seals, the first seat ring, the first rubber ring, the second O-ring seals, second valve seat ring and the second rubber ring; Embedded the first seat ring between described valve plate and left valve barrel; Between described the first seat ring and left valve barrel, the first O-ring seals in embedding; Embedded second valve seat ring between described valve plate and right valve barrel; Between described second valve seat ring and right valve barrel, the second O-ring seals in embedding; On described the first seat ring, second valve seat ring, be respectively equipped with groove, be embedded with respectively the first rubber ring and the second rubber ring in the groove of described the first seat ring, second valve seat ring, described the first rubber ring and the second rubber ring are pressed on valve plate respectively.
As further improvement of the utility model, described the first rubber ring and the second rubber ring are comprised of internal layer, skin respectively, and skin is wrapped on internal layer; Internal layer is elastic sheet metal, and skin is polytetrafluoroethylmaterial material.
As further improvement of the utility model, described the first rubber ring and the second rubber ring are shaped as L shaped.
Compared with the prior art the utility model has the following advantages:
Because its sectional shape is L shaped, in groove, do not produce distortion, so can not roll when to-and-fro motion in groove.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.Meanwhile, bit shift compensation is made in the gap that can produce the wearing and tearing of outer layer rubber by elastic sheet metal in L shaped seal ring, guarantees the durability of seal ring, has also greatly improved the working life of diamond valve.
Accompanying drawing explanation
Fig. 1 is the use phase diagram of the utility model structure.
Embodiment
The utility model is further described in connection with the embodiment in accompanying drawing below:
Valve plate 2, the first O-ring seals 3, the first seat ring 4, the first rubber ring 5, the second O-ring seals 6, second valve seat ring 7 and the second rubber ring 8 as shown in Figure 1: a kind of L shaped seal arrangement of diamond valve comprises valve body 1(left valve barrel 1a, right valve barrel 1b).
Described valve plate 2 is clipped between left valve barrel 1a and right valve barrel 1b, and left valve barrel 1a and right valve barrel 1b are connected and formed valve body 1 by bolton.Embedded the first seat ring 4 between described valve plate 2 and left valve barrel 1a; Between described the first seat ring 4 and left valve barrel 1a, the first O-ring seals 3 in embedding; Embedded second valve seat ring 7 between described valve plate 2 and right valve barrel 1b; Between described second valve seat ring 7 and right valve barrel 1b, the second O-ring seals 6 in embedding; On described the first seat ring 4, second valve seat ring 7, be respectively equipped with groove, be embedded with respectively the first rubber ring 5 and the second rubber ring 8 in the groove of described the first seat ring 4, second valve seat ring 7, described the first rubber ring 5 and the second rubber ring 8 are pressed in respectively on valve plate 2.Described the first rubber ring 5 and the second rubber ring 8 are shaped as L shaped.L shaped the first rubber ring 5 and L shaped the second rubber ring 8 its in compressive state, rely on the elastic force of itself to be tightly pressed on valve plate 2, thereby guarantee that diamond valve has good tightness.
Described L shaped the first rubber ring 5 is identical with L shaped the second rubber ring 8 structures.Described L shaped the first rubber ring 5 is comprised of internal layer, skin, and skin is wrapped on internal layer; Internal layer is elastic sheet metal, and skin is polytetrafluoroethylmaterial material.Elastic sheet metal, guarantees that L shaped seal ring has excellent elasticity, guarantees remarkable sealing effect, and polytetrafluoroethylmaterial material has wear-resisting feature, thereby makes it have good durability.
During the work of rhombus flow control valve, by the switching of valve plate 2, control the size of flow.L shaped rubber ring relies on himself elastic force, tightly leans against on valve plate 2.Because its sectional shape is L shaped, in groove, do not produce distortion, so can not roll when to-and-fro motion in groove.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.Meanwhile, effective bit shift compensation is made in the gap that can produce the wearing and tearing of outer layer rubber by elastic sheet metal in L shaped seal ring, guarantees the durability of seal ring, has also greatly improved the working life of diamond valve.
