Description
[technical field]
The utility model relates to a kind of moushroom valve.
[background technique]
Existing moushroom valve generally all is provided with the external leakage sealing configuration, generally relates to leakage structure outward to be: offer the hole that allows rotating shaft stretch out on valve body, rotating shaft is stretched out from the hole.Periphery in the hole carries out packing seal afterwards, is equipped with a pressure ring afterwards again above filler, makes it to compress the sealing material.
But after being to use for a long time, the space can appear in the wearing and tearing between stuffing box packing meeting contraction or rotating shaft and the filler, so the phenomenon of external leakage can occur, whole moushroom valve is scrapped.
[model utility content]
The utility model purpose is to have overcome deficiency of the prior art and a kind of simple in structure, moushroom valve that can prevent external leakage is provided.
In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposal:
Moushroom valve, include valve body, in valve body, be provided with the fluid passage that can allow fluid pass through, in valve body, also be provided with valve pocket, in valve pocket, be provided with the valve disc that the fluid passage can be cut off, also be provided with in valve body and can drive the rotating assembly that valve disc moves around and realizes fluid passage open and close effect in valve pocket, the top of the rotating shaft on the described rotating assembly is stretched out the valve body outside and is connected with one handle;
It is characterized in that rotating shaft on valve body stretches out the place and be provided with the stuffing box packing that prevents external leakage, above stuffing box packing, be provided with the pressure ring that it can be pushed down, above pressure ring, be provided with the pressing plate that pressure ring is withstood, on valve body, be provided with the regulation structure that the can regulate pressing plate is pushed down the pressure size of pressure ring.
Aforesaid moushroom valve is characterized in that described regulation structure includes one and regulates bolt, is provided with the adjusting screw on valve body, has to allow on pressing plate and regulates the through hole that bolt passes, and the adjusting bolt passes through hole and matches with the adjusting screw.
Aforesaid moushroom valve is characterized in that also being provided with one and can prevent the belleville spring that becomes flexible between the nut of regulating bolt and through hole.
Aforesaid moushroom valve is characterized in that an end that stretches out the valve body outside in rotating shaft is provided with a screw, and taper knob is placed with a dish-shaped spring at the screw upper surface in rotating shaft, and a bolt passes belleville spring and is connected with screw.
The utility model compared with prior art has following advantage: the utility model is provided with a pressure ring above stuffing box packing, above pressure ring, be provided with a pressing plate, on valve body, be provided with the regulation structure of regulating the platen pressure size, after in case wearing and tearing appear in filler, the phenomenon that stuffing box packing will occur becoming flexible at this moment with regard to the regulation structure on the regulation valve body, makes pressing plate compress pressure ring once more, it force pressure ring to push down filler tightly, so the external leakage phenomenon can not occur.
Secondly regulation structure is matched by a bolt and one group of dish spring, realizes the function of regulating, have simple in structure, save performance such as material.
[description of drawings]
Fig. 1 is a sectional drawing of the present utility model.
[embodiment]
Below in conjunction with accompanying drawing the utility model is described in detail:
As shown in the figure, moushroom valve includes valve body 1, is provided with the fluid passage 2 that can allow fluid pass through in valve body 1, also is provided with valve pocket 3 in valve body 1, is provided with the valve disc 4 that fluid passage 2 can be cut off in valve pocket 3.Also be provided with in valve body 1 and can drive the rotating assembly 5 that valve disc 4 moves around and realizes fluid passage 2 open and close effects in valve pocket 3, the top of the rotating shaft 51 on the described rotating assembly 5 is stretched out valve body 1 outside and is connected with one handle 52.Described rotating assembly 5 also includes the cross bar 53 that is connected with valve disc 4 with rotating shaft 51.
In the time will opening moushroom valve, handle with sleeve 52 and then rotates rotating shaft 51, and 51 drive cross bars of rotating shaft 53 rotate.Because cross bar 53 is that rotate in the axle center with rotating shaft 51, does the camber line slip so 53 of cross bars can drive valve disc 4 in valve pocket 3, makes valve disc 4 away from fluid passage 2, makes fluid passage 2 unobstructed.
Rotating shaft 51 on valve body 1 is stretched out the place and is provided with the stuffing box packing 6 that prevents external leakage, above stuffing box packing 6, be provided with the pressure ring 7 that it can be pushed down, above pressure ring 7, be provided with the pressing plate 8 that pressure ring 7 is withstood, on valve body 1, be provided with the regulation structure 9 that can regulate pressing plate 8 is pushed down the pressure size of pressure ring 7.This regulation structure 9 includes one and regulates bolt 91, is provided with on valve body 1 and regulates screw 92, has to allow on pressing plate 8 to regulate the through hole 93 that bolt 91 passes, and adjusting bolt 91 passes through hole 93 and matches with adjusting screw 92.
After moushroom valve has used of a specified duration, because the phenomenon that filler 6 becomes flexible then can appear in the wearing and tearing between rotating shaft 51 and the stuffing box packing 6.At this moment under the pretightening force effect of dish spring 94, make pressing plate 8 down compress pressure ring 7, then pressure ring 7 will continue down to compress stuffing box packing 6, the phenomenon that makes filler 6 can not occur becoming flexible.
Between the nut of regulating bolt 91 and through hole 93, also be provided with one and can prevent from the belleville spring 94 that becomes flexible to make it to produce pretightening force, guarantee long term seal, reduce and keep in repair frequency.
An end that stretches out valve body 1 outside in rotating shaft 51 is provided with a screw 11, and handle 52 is enclosed within the rotating shaft 51, is placed with dish-shaped spring 12, one bolts 13 at screw 11 upper surfaces and passes belleville spring 12 and be connected with screw 11.The belleville spring 12 that is provided with also is to make it to produce pretightening force, guarantees rotating assembly 5 stress equalizations, and setting height(from bottom) that can regulating handle 52.
