Abstract
The utility model discloses a sealing performance is good, long service life's two -way inflation gate valve of heavy -calibre, including the valve gap, be equipped with the valve rod in the valve gap, the valve gap lower extreme is equipped with the valve body, be equipped with the flashboard in the valve body, spacing backplate is installed to the flashboard both sides, the flashboard freely is connected with the rocker, the rocker freely is connected with the slider, the flashboard has two, two the flashboard all is equipped with the inclined plane that can cooperate the contact. The utility model discloses an on the good sealing performance's of assurance heavy -calibre gate valve the basis, prolongs the life of heavy -calibre gate valve, reduces the switch moment of torsion of valve.
Description
Technical field
The utility model belongs to expansion sluice valve technical field, particularly relates to heavy caliber expansion sluice valve.
Background technique
Heavy-caliber gate valve is applicable to block or connect the medium in pipeline, selects different materials, can be applicable to the mediums such as water, steam, oil product, nitric acid, acetic acid, Oxidant, urea respectively.Petroleum pipeline is applied more.Common gate valve in the market, operational torque is large, easily makes the damages such as valve body valve rod during operation, particularly heavy-caliber gate valve, and common gate valve can not meet the bilateral valve seat when opening or close and is all in impaction state, medium can wash away sealing surface, shortens the life-span of valve.
Model utility content
In order to solve the problem, the utility model provides the two-way expansion sluice valve of heavy caliber of a kind of good seal performance, long service life.
According to an aspect of the present utility model, there is provided a kind of heavy caliber two-way expansion sluice valve, comprise valve gap, be provided with valve rod in described valve gap, described valve gap lower end is provided with valve body, flashboard is provided with in described valve body, described flashboard both sides are provided with spacing backplate, and described flashboard is freely connected with rocking bar, and described rocking bar is freely connected with slide block, described flashboard has two, and two described flashboards are equipped with the inclined-plane that can coordinate contact.
In some embodiments, rocking bar is freely connected on two shoe brake plates by rocking bar connecting thread.
In some embodiments, slide block is freely connected with rocking bar by slide block connecting thread.
In some embodiments, described flashboard is provided with groove, and described slide block is arranged in groove.
The utility model adopts two pieces of flashboards coordinated by two inclined-planes, by the drive of expansion mechanism and the restriction of spacing backplate, two shoe brake plates is expanded in completely open and close position and is adjacent to sealing surface, hold tightly and depart from both sides valve seat in opening-closing process.In opening and closing position, two shoe brake plates compress both sides valve seat respectively under expansion mechanism effect, make sealing surface can not be subject to the erosion of medium and wash away, extend working life; In opening-closing process, by the effect of expansion mechanism and spacing backplate, two shoe brake plates are held tightly, leaves both sides valve seat, efficiently reduce operation moment of torsion.Its beneficial effect is: on a kind of basis ensureing heavy-caliber gate valve excellent sealing performance of the utility model design, extend the working life of heavy-caliber gate valve, reduce the switching torque of valve.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-valve gap, 2-valve rod, 3-valve body, 4-flashboard, the spacing backplate of 5-, 6-rocking bar, 7-slide block, 8-rocking bar connecting thread, 9-slide block connecting thread.
Embodiment
Be further described below in conjunction with accompanying drawing 1 pair of the utility model.Accompanying drawing 1 schematically shows the two-way expansion sluice valve of the utility model heavy caliber, comprise valve gap 1, valve rod 2 is provided with in described valve gap 1, described valve gap 1 lower end is provided with valve body 3, is provided with flashboard 4 in described valve body 3, and described flashboard 4 both sides are provided with spacing backplate 5, described flashboard 4 is freely connected with rocking bar 6, described rocking bar 6 is freely connected with slide block 7, and described flashboard 4 has two, and two described flashboards 4 are equipped with the inclined-plane that can coordinate contact.
Preferably, rocking bar 6 is freely connected on two shoe brake plates 4 by rocking bar connecting thread 8.
Preferably, slide block 7 is freely connected with rocking bar 6 by slide block connecting thread 9.
Preferably, described flashboard 4 is provided with groove, and described slide block 7 is arranged in groove.
By reference to the accompanying drawings 1, flashboard 4 coordinates inclined-planes to realize expanding by two, and rocking bar 6 is freely connected on two shoe brake plates 4 by rocking bar connecting thread 8.Slide block 7 is freely connected with rocking bar 6 by slide block connecting thread 9, and be arranged in the groove of flashboard 4, prevent it from producing the inclination of wide-angle, spacing backplate 5 is arranged on flashboard 3 both sides, this kind of structures shape, when rocking bar 6 produces swing, two place's rocking bar connecting threads 8 produce height difference, thus make the relative displacement produced on height of two shoe brake plates 4 realize expanding.When flashboard 4 moves to the position needing to expand, the spacing backplate 5 of corresponding side loses position-limiting action, makes slide block 7 to a lateral movement, drives rocking bar 6 to tilt, thus makes flashboard 4 produce expansion.Two shoe brake plates 4 all can be fitted tightly with both sides valve seat when open and close.In flashboard opening-closing process, the both sides of slide block 7 contact with two pieces of spacing backplates 5, limit rocking bar 6 and tilt, thus limit flashboard 4 generation expansion.Make two shoe brake plates 4 hold tightly together, depart from both sides valve seat.
Above-described is only mode of executions more of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from creation design of the present utility model; can also make other distortion and improve, these all belong to protection domain of the present utility model.
