Abstract
The utility model relates to an industrial valve, which is characterized in that the outside of the valve is provided with a tee valve body whose interspace is vertically provided with a rotating shaft which is provided with an eccentric wheel with a symmetrical structure of both sides so as to form a left pressing cover and a right pressing cover with the eccentric wheel; the inner is provided with a spring whose outside is provided with a guiding plunger; the plunger forms a seal structure with a cover. One end of the pressing cover is shifted by rotating of the eccentric and the guiding plunger is pulled out at the other side to form a structure of one side closing while the other side opening to achieve the aim of changing direction. The utility model has the advantages of simple structure, long service life, steady property, good tightness, and agility for using by using the plunger as the switching component.
Description
The utility model belongs to industrial pipeline road selector valve.
What existing market was widely used is the QHF fuel tap, and its structure is that the turnover bore does not wait, and differs 1/2 times.The centre is line sealing between steel ball and the steel bushing, commutation is to make cutting movement by ball on potted line, its shortcoming is because the bore difference, make it to reduce with the supporting oil pressure of main frame, the pressure loss increases, not enough to the machinery charge oil pressure like this, equipment can not get lubricated fully, has reduced the working life of machinery widely; Secondly because ball-valve structure repeatedly uses poor sealing performance, cause fluid to leak outside, the life-span is short, secondly is that the difficult band of this kind valve is pressed commutation, repeatedly commutation under pressure reduction 0～16kg condition, and sealing part is worn and torn and is produced distortion, causes fluid to leak at last.
For solving above deficiency, the purpose of this utility model provides a kind of pipeline road selector valve, adopts manual eccentric wheel and structure of piston, has realized the purpose of pipeline road band pressure commutation oil transportation effectively.
Structural design of the present utility model is achieved in that its structure is that the outside is a three way valve (11), valve body (11) intermediate vertical is equipped with rotating shaft (12), eccentric wheel (1) is housed in rotating shaft, eccentric wheel (1) both sides device is a symplex structure, be connected to left and right sides gland (2) with eccentric shaft, in the gland (2) is pressure spring (3), it below the spring left and right sides guide piston (4), guide piston (4) lower end is the cone that has the inclined-plane, the cone front end has four locating columns (10), the outside is added with O-ring seal (9), is double-sealing with valve body (11) mouth of pipe inclined-plane and is connected, and rubber seal (8) is equipped with at valve body (11) mouth of pipe place in addition.
Left and right sides gland (2) wherein, rounded sleeve pipe, a crossbeam is fixed on the top, following vertical protruding formation outer.
Guide piston (4) one ends fasten spring (3), are placed with left and right sides pressing plate (5) at the Ping Kouchu of guide piston (4) simultaneously, are screwed on guide piston (4).
Pressing plate (5) two ends are connected by two parallel pull bars (6) (7) with crossbeam two ends, opposite gland (2) top respectively.
Its working procedure is: when 180 ° on the handle on the rotating shaft, rotating shaft drives eccentric wheel and rotates, the long radius that contacts with eccentric wheel is pressed to the outside, the gland that is attached thereto is pressed towards the outside simultaneously, gland outwards moves in fixing pressing plate, spring compressing guide piston in the gland outwards leans on, make the vertebra body and the interior circle of the valve body inclined-plane of front be sealing state, close this side valve door, because the crossbeam on gland top and the pull bar effect between the guide piston of opposite make guide piston move inward simultaneously, centrum inclined-plane and valve body are thrown off, this side valve door conducting, otherwise in like manner.Therefore a rotatable handle is 180 °, has just reached the purpose of oil transportation valve commutation, and this kind valve can be simultaneously be fitted together use with two groups or three groups are overlapping.
Detailed structure of the present utility model is provided by following examples and accompanying drawing.
Fig. 1 is a pipeline road selector valve structure principle chart.
Its structure is known by Fig. 1.(10) be valve body, generally cast by metal, (9) be intermediate rotary shaft, its top is equipped with handgrip, being with eccentric wheel (1) above the rotating shaft (12) is connected with eccentric wheel (1) and is a left side, right gland (2), the inside is pressure spring (3), be with pressing plate (5) on the gland (2), be guide piston (4) below, piston nose is fixed with locating column (10), and O-ring seal (9) is equipped with in the outside, middle with screw, in the outlet both sides rubber sealing boot (8) is housed, is connected by pull bar (6) (7) between the crossbeam on gland (2) top and the pressing plate on opposite, its arrow is represented oily flow path direction.
The advantage of the utility model: simple in structure, adopt guide piston as switch, use flexibly the life-span Long, stable performance, good seal performance.
