Description
Technical field
The utility model relates to a kind of valve, particularly a kind of two way sealed formula butterfly valve.
Background technique
At present, the industrial valves door type is various, and large bore valves is mainly used in tap water pipeline, blow-off line and the gas-pipe line etc. of water factory, mainly plays the Flow-rate adjustment of fluid, gas medium and ends effect.But existing reed valve is generally one-way sealing formula butterfly valve, can't realize two way sealed as traditional two eccentric flange butterfly valves, can only unidirectional pressure-bearing; And center line wafer type butterfly valve can bidirectional bearing, but because its structure is limit, can not make bigger bore, and existing large-diameter butterfly valve often sealing effect is not good enough; Therefore develop heavy caliber two way sealed formula butterfly valve and promptly become the blank that this field urgent need is filled up.
The model utility content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of two way sealed formula butterfly valve of simple in structure, reliable performance is provided.
The technological scheme that the utility model adopted is for achieving the above object: a kind of two way sealed formula butterfly valve is connected and composed by valve body, valve plate, rotating shaft, sealing gland, locating stud, axle sleeve, Simmer ring, connecting key, connection bearing, supporting frame and seal joint; Valve body top is provided with the connection bearing, and the valve body bottom is provided with supporting frame; The rotating shaft top is provided with the connecting key that connects transmission device; Rotating shaft places in the axle sleeve and is positioned valve body, and valve plate places in the valve body fixedlys connected with rotating shaft by locating stud, and rotating shaft and sealing gland joint are provided with Simmer ring; It is characterized in that valve plate with rotating shaft to being called the biplate frame shape, the every valve plate outside is respectively equipped with the valve plate seal ring, which is provided with seal joint, in the corresponding valve plate seal ring valve body chamber around being provided with the valve seals that cooperatively interacts with it.
Positive and negative bi-directional symmetrical setting of described valve plate seal ring and valve seals and interference fit each other.
Described valve seals is that ring bodies that stainless steel or Cuprum alloy are made is sphere and is symmetricly set in the valve body chamber, and frame shape biplate valve plate running orbit in valve seals is a sphere.
The beneficial effects of the utility model are: this two way sealed formula butterfly valve is because valve plate is the biplate frame-shaped structure, both can guarantee very strong bearing strength, be convenient to the circulation of medium again, improve its discharge value, no matter medium from a left side or right exert pressure, valve all can obtain one positive one anti-two seals and guarantee ne-leakage, therefore is suitable for making the large bore valves that diameter is 400mm～2000mm more.Valve seals the formation spheric structure is set, so the running orbit of valve plate forms a Spherical Surface S R; Valve seals adopts stainless steel material to be directly welded in valve body, effectively improves the corrosion resistance of valve; The valve plate seal ring adopts rubber to make, and cooperatively interacts firmly with valve seals one soft one and reduces between the two friction, and sealing effect is very remarkable.This butterfly valve is realized two way sealed ne-leakage, bidirectional bearing, reliable performance; And effectively reducing valve opening and closed torque, easy and simple to handle, low energy has been filled up the blank of this field large bore valves with its its specific structure design.

Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, details are as follows to embodiment, structure, feature that foundation the utility model provides:
As Fig. 1～shown in Figure 4, a kind of two way sealed formula butterfly valve is by valve body 1, valve plate 2, rotating shaft 3, sealing gland 4, locating stud 5, axle sleeve 6, Simmer ring 7, connecting key 8, connect bearing 9, supporting frame 10 and seal joint 11 and connect and compose; Valve body 1 top is provided with and connects bearing 9, and valve body 1 bottom is provided with supporting frame 10; Rotating shaft 3 tops are provided with the connecting key 8 that connects transmission device; Rotating shaft 3 places in the axle sleeve 6 and is positioned valve body 1, and valve plate 2 places in the valve body 1 fixedlys connected with rotating shaft 3 by locating stud 5, and rotating shaft 3 is provided with Simmer ring 7 with sealing gland 4 joints; It is characterized in that valve plate 2 is called the biplate frame shape with 3 pairs of rotating shafts, every valve plate 2 outsides are respectively equipped with valve plate seal ring 12,13, which is provided with seal joint 11, in corresponding valve plate seal ring 12,13 valve bodies 1 chamber around being provided with the valve seals 14,15 that cooperatively interacts with it.Biplate frame shape valve plate 2 structures can effectively reduce flow resistance, improve flow coefficient.
Described valve plate seal ring 12,13 and valve seals 14,15 positive and negative bi-directional symmetrical settings and interference fit each other.
The ring bodies that described valve seals 14,15 is made for stainless steel or Cuprum alloy is sphere and is symmetricly set in valve body 1 chamber, and frame shape biplate valve plate 2 running orbit in valve seals 14,15 is Spherical Surface S R, can effectively reduce the valve torque.Valve seals 14,15 can adopt corrosion resistant metallic material such as stainless steel or Cuprum alloy and valve body 1 to be welded as a whole.
As shown in Figure 3, Figure 4, no matter medium still exerts pressure from dextrad from left-hand, and valve body 1 is equipped with one positive one anti-two seals circle, and when valve plate 2 was closed, seal ring is tight mutually to be cooperated; When medium when left-hand is exerted pressure, the reverse sealing configuration of being made up of valve plate seal ring 12, valve seals 14 plays the low pressure seal effect, when pressure improves or is very big, medium can be by entering in valve plate 2 chambeies, but the forward sealing configuration of being formed by valve plate seal ring 13, valve seals 15 ends, and the forward sealing configuration can bear high pressure; From dextrad exert pressure with left-hand in like manner.Therefore this structure is guaranteed valve no matter left-hand still is a dextrad to bear pressure, bears high pressure or low pressure and all can reach reliable sealing effect.Valve seals 14,15 the formation spheric structure is set, so the running orbit of valve plate 2 forms a Spherical Surface S R; See on the whole to be similar to big ball valve, valve plate 2 is the part of sphere, under the support of rotating shaft 3 is rotated, turns round in valve seals 14, the 15 corresponding Spherical Surface S R that form, and realizes ending and regulating action medium.
The transmission device that is connected with connecting key 8 in the butterfly valve can be matched handle, manual heads opening/shutting valve according to technological requirement; And configurable electrical header, pneumatic first-class, realize integrated control and automation.
Can make various specification as required in the enforcement, as 400mm～2000mm bore, this two way sealed formula butterfly valve can be installed on ground or underground by flange on demand, and simple and easy to do, Applicable scope is very extensive.
