Description
Technical field
The utility model relates to valve field, refers to a kind of slag-off valve especially.
Background technique
Be applied to the slag-discharging valve of the concentrate in hydraulic(-ash) sluicing, mine tailing, ash-slag disposal system at present, it comprises valve body, valve body has inlet passage and discharge route, in valve body, has flashboard, and flashboard is connected with lifting opening/closing mechanism.The cavity holding flashboard is had between valve body and valve gap, when cavity dust stratification is gone up to a certain extent, flashboard switch is not in place, flashboard is in throttle, causes flow velocity to accelerate, fine and close front cover serious wear, sealing effect is poor, valve premature failure, the shortcoming that valve working life is short, increases cost and also has a strong impact on production system and run.
Model utility content
The utility model proposes a kind of slag-off valve, solve the problem that the not in place and sealing surface wear of flashboard switch in prior art causes sealing effect difference.
The technical solution of the utility model is achieved in that a kind of slag-off valve, comprise valve body, valve rod and flashboard, described flashboard is fixedly connected with valve rod, described valve body is provided with the valve pocket circulated for liquid, described valve body is installed on valve seat, it is characterized in that, described valve seat is provided with standing groove, and described flashboard passes described valve pocket and is placed in standing groove; The two side of described valve seat offers mounting groove respectively; All be provided with seal arrangement one and seal arrangement two in the mounting groove of described both sides, described seal arrangement one can stretch and can be formed to conflict with described flashboard respectively to standing groove direction with the free end of seal arrangement two and be connected.
Preferably, be provided with elastic component in described mounting groove, the end abutment of described seal arrangement one is in elasticity
Part; The end abutment of described seal arrangement two is in elastic component.
Preferably, described seal arrangement one be arranged in parallel with the sidewall of seal arrangement two along valve seat.
Preferably, described seal arrangement one and seal arrangement two are seal ring.
Preferably, the underpart of described flashboard is arranged with rubber sleeve.
Preferably, described elastic component is Returnning spring.
Preferably, the cross section of described flashboard underpart is triangle or trapezoidal.
By the technological scheme of above-mentioned employing, valve body is when opening, and seal arrangement one and seal arrangement two stretch out closed together, can prevent bits from entering in standing groove; Ensure that standing groove inside does not accumulate dust, valve body can be closed and be put in place; When closedown valve pocket, flashboard moves downward and moves in standing groove by valve pocket, and the two side that seal arrangement one and seal arrangement two are affixed on flashboard is respectively opened to both sides, the effect played: 1, seal action; 2, flashboard is protected not to be worn; The cross section of flashboard underpart is so arranged, and underpart area is little to be conducive to closedown and to put in place; Rubber sleeve can play flashboard: the sealing improving flashboard and standing groove; Reduce the wearing and tearing of flashboard and standing groove; Prevent valve premature failure, improve the working life of valve.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the utility model structural representation;
Fig. 2 is the structural representation that the utility model Stamping Steel Ribbon is arranged.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1-2, a kind of slag-off valve, comprises valve body 2, valve rod 1 and flashboard 3.Described flashboard 3 is fixedly connected with bolt with valve rod 1.Described valve body 2 is provided with the valve pocket 6 circulated for liquid.Described valve body 2 is installed on valve seat 4.Described valve seat 4 is provided with standing groove 5.Described flashboard 3 passes described valve pocket 6 and is placed in standing groove 5, realizes the closedown to valve pocket 6.The both sides of described standing groove 5 are respectively equipped with seal arrangement 1 and seal arrangement 2 11.Seal arrangement 1 be arranged in parallel with the sidewall of seal arrangement 2 11 along valve seat 6.One end of seal arrangement 1 and seal arrangement 2 11 is separately fixed on elastic component 9, and every block elastic component 9 is fixed in the mounting groove 12 on the both sides inwall of valve seat 4 separately.Described seal arrangement 1 can stretch and can be formed to conflict with described flashboard respectively to standing groove 5 direction with the free end of seal arrangement 2 11 and be connected.Elastic component 9 is Returnning spring.Seal arrangement 1 and seal arrangement 2 11 are seal ring
When closedown valve pocket 6, flashboard moves downward and moves in standing groove 5 by valve pocket 6, and the two side that seal arrangement 1 and seal arrangement 2 11 are affixed on flashboard 3 is respectively opened to both sides.
Wherein, the cross section of described flashboard 3 underpart is triangle or trapezoidal.The underpart of flashboard 3 is arranged with rubber sleeve 7.
Setting like this, when valve body 2 is when opening, seal arrangement 1 can prevent bits from entering in standing groove 5 together with intersecting with seal arrangement 2 11; Ensure that standing groove 5 inside does not accumulate dust, valve body 2 can be closed and be put in place; When closedown valve pocket 6, flashboard 3 moves downward and moves in standing groove 5 by valve pocket 6, and the two side that seal arrangement 1 and seal arrangement 2 11 are affixed on flashboard 3 is respectively opened to both sides, the effect played: 1, seal action; 2, flashboard 3 is protected not to be worn; The cross section of flashboard 3 underpart is so arranged, and underpart area is little to be conducive to closedown and to put in place; Rubber sleeve 7 pairs of flashboards 3 can play: the sealing improving flashboard 3 and standing groove 5; Reduce the wearing and tearing of flashboard 3 and standing groove 5; Prevent valve premature failure, improve the working life of valve.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
