Description
Technical field
The utility model belongs to a kind of butterfly valve, specifically a kind of upper dress formula bidirectional sealed butterfly valve.
Background technique
Butterfly valve is Flap valve again, it is the simple modulating valve of a kind of structure, also the valve butterfly valve that can be used in the mode work of the switch control rule of low pressure pipeline medium refers to that closure member (flap or butterfly plate) is disk simultaneously, rotate a kind of valve reaching open and close around valve shaft, valve can be used for the flowing controlling all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.On pipeline, main rising is cut off and throttling action.Butterfly valve open-shut device is a discoidal butterfly plate, rotates in valve body around the axis of himself, thus reaches the object opening and closing or regulate.
Poor sealing performance on tradition butterfly valve overall performance and can not two way sealed, the rubber elastomer in butterfly valve in using continuously, can produce tear, wear and tear, aging, even obscission of boring a hole.And traditional hot vulcanization process is difficult to the needs adapting to field repair, special equipment to be adopted during reparation, consume a large amount of heat energy and electric energy, waste time and energy.
Model utility content
The purpose of this utility model is, for the shortcoming of traditional seal valve, provides a kind of upper dress formula bidirectional sealed butterfly valve, easy to maintenance, decreases maintenance cost.
For solving the problems of the technologies described above, the technological scheme that the utility model is taked is: dress formula bidirectional sealed butterfly valve in one, the pressing plate comprising valve body and install in it and butterfly plate, pressing plate and butterfly plate are connected as a single entity, it is characterized in that: the upper end of described valve body is provided with opening, from then on the pressing plate be connected as a single entity and butterfly plate can directly be taken out by opening.
Also comprise valve gap, valve gap is located by taper pin, and hexagon nut, spring washer and stud are arranged on the upper end open place of valve body, are provided with valve rod in valve gap, and valve rod extend into the lower bottom of valve body through butterfly plate, and is fastenedly connected by taper pin.
Be provided with seal ring between described pressing plate and butterfly plate, sealing circle is fitted on the internal surface of valve body contact, and described pressing plate and butterfly plate are fastenedly connected by socket head screw.
Be provided with filler between described valve gap and valve rod, and linked together by Gland, hexagon nut, spring washer and stud and valve gap.
Described valve gap is connected with support by hexagon nut, spring washer and stud, and support is connected with worm wheel head with stud by hexagon nut, spring washer, and worm wheel head is arranged on valve rod by key.
Compared with prior art, the beneficial effects of the utility model are: the utility model product pulls down valve gap directly can unload lower flashboard, and this structural design is convenient for changing flashboard, and easy to maintenance, decreases maintenance cost; In addition, the utility model structure is simple, and practical, fabricating cost is not high, and this product is adapted at promoting the use of in like product.
