Abstract
The utility model relates to a balanced type regulating valve. The balanced type regulating valve comprises a valve body, a valve rod, a valve cap, a valve seat and a valve clack. The valve rod penetrates through the valve cap and enters into the valve body, the lower end of the valve rod is connected with the valve clack, the valve clack is closely connected with the valve seat, the valve cap is fixedly connected with the valve body through a bolt, a guiding cover is connected between the valve body and the valve cap, the lower end of the guiding cover is connected with a throttling cover, and a sealing ring is arranged between the guiding cover and the throttling cover. The balanced type regulating valve has the advantages that the sealing ring can be well fixed and can not slide easily, wear intensity is reduced, and a sealing effect can last for a long time.
Description
Technical field
The utility model relates to a balanced type modulating valve.
Background technique
The modulating valve that uses at present, its seal ring is contained in the upper end of flap, by being fixed with pad and snap ring, use fixing unstable between such structure pad and the snap ring, seal ring does not reach good fixed effect, when valve rod starts or closes, seal ring is subjected to displacement easily, thereby sealing effect is reduced, and make the ring wear aggravation, reduce its working life.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of flap and shroud between seal ring can well fix and nonabradable modulating valve.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a modulating valve, comprise valve body, valve rod, valve gap, valve seat and flap, valve rod passes that valve gap enters valve body and the lower end links to each other with flap, and flap and valve seat match closely, and valve gap and valve body are bolted to connection, being connected with guiding between valve body and the valve gap shrouds, guiding is shrouded the lower end and is connected with throttling and shrouds, and guiding is shrouded and throttling is equipped with O-ring seal between shrouding, and flap is close in O-ring seal.
Use the modulating valve of said apparatus, between its seal ring was close to that guiding is shrouded and throttling shrouds, when valve rod started or closes, seal ring can be good at fixing, and was difficult for being subjected to displacement, and wear intensity reduces, and can be permanent play seal action.
Description of drawings
Fig. 1 is the structural drawing of modulating valve of the present utility model.
Embodiment
By structural drawing shown in Figure 1 as can be known, valve rod 5 passes valve gap 10 and enters in the valve body 9, the lower end of valve rod 5 is connected with flap 2, the middle part of flap 2 has a circular groove that valve rod 5 can just be embedded, closely match between flap 2 and the valve seat 1, be connected by bolt 3 between valve gap 10 and the valve body 9, bolt 3 usefulness nuts 4 are tightened fixing, there is the upper end of an inner chamber and inner chamber that one annular groove is arranged in the middle of the valve body 9, the bottom of valve gap 10 is concavo-convex, the outer wall of valve gap 10 protuberances is close to the lumen channels place of valve body 9, guiding is shrouded the just in time groove of embedding and valve gap 10 of 6 concave-convex surfaces and top, guiding is shrouded between the protuberance that 6 protuberance is in the lumen channels of valve body 9 and valve gap 10, guiding is shrouded 6 lower end and is connected with throttling and shrouds 8, guiding shroud 6 and throttling shroud 8 centre one annular groove arranged, seal ring 7 can just be imbedded, the inwall of seal ring 7 is close to flap 2.
