Description
Technical field
The utility model relates to valve technology field, is particularly a kind ofly mainly used in the wear-resisting discharge valve of the top extending type of discharging at the bottom of tank.
Background technique
Along with the devices such as Coal Chemical Industry, petrochemical industry, metallurgy are constantly to the development of high parameter, the working condition that process apparatus uses is more and more harsher; The discharge that the raw material major part of multiphase flow needed for process apparatus is stored in raw material in batch can, at the bottom of tank needs to use discharge valve, occurs following problem in discharge valve using process at the bottom of current tank:
1, plunger valve fit tightly by plunger seal and sealing surface of seat realize sealing, by the to-and-fro motion of plunger to realize the keying of valve, in reciprocating process, grit medium easily enters gap between plunger and valve body, causes plunger seriously to pull, and easily occurs seal leakage; There is the dead band of buildup at fully open position in plunger, amasss the sticky material not easy cleaning in dead band, and valve opening moment becomes large, operating difficulties;
2, bottom open type discharge valve flap when fully open position moves down in valve flowing channel, and flap is unfavorable for the flowing of medium, affects the flow of valve in valve flowing channel;
3, traditional discharge valve runner does not carry out special superpressed process, and because multiphase flow medium solid content height particle is hard, the runner of contact medium easily occurs wearing and tearing and washes away, and working life is short.
Model utility content
Technical problem to be solved in the utility model to provide a kind of sealability reliable, without buildup dead band, and the wear-resisting discharge valve of top extending type of wear-resisting resistance to erosion long service life.
In order to solve above technical problem, the utility model provides the wear-resisting discharge valve of a kind of top extending type, comprise flap, valve seat, valve body, guiding rib, valve rod, gasket seal, screw, the flushing mouth of pipe, Stuffing box, dust ring, gland and umbrella gear, valve seat is arranged on valve body, the top of valve seat is provided with the flap of top extending type, the unlatching of flap is by guiding rib location, valve rod is connected on flap, valve rod and Stuffing box contact position are provided with dust ring, the pressured cover of dust ring compresses, and the keying of valve is rotated handwheel and driven umbrella gear to realize.
Described flap is connected with the lower end of valve rod by valve clack cover.
The stem surface spraying abrasion-proof alloy-layer of described flap, valve channel, guiding rib, valve seat and valve base channel, contact medium, effectively improves the wear-resisting erosion resistibility of valve, extends valve working life
With the flushing mouth of pipe on described valve body, body cavity is rinsed.
Described Stuffing box top adopts dustproof construction, effectively solves to cause valve cannot normal switch problem because valve rod is stuck
Described valve seat be top extending type more can dismantle valve seat construction.
The beneficial effects of the utility model:
1) adopt the flap of top extending type, flap upwards poppet is opened, and flap rises to top fully open position, the flowing of favourable medium; Flap is downward, decline valve closing, flap closing process medium be conducive to valve seal from gravity and internal pressure, sealability is reliable;
2) what adopt top extending type more can dismantle valve seat construction, and effectively solve plunger exists buildup dead band problem at fully open position, rapid operation, can more dismantle valve seat construction valve seat easy to maintenance;
3) the stem surface spraying abrasion-proof alloy-layer of flap, valve channel, guiding rib, valve seat and valve base channel, contact medium, effectively can improve the wear-resisting erosion resistibility of valve, extends valve working life;
4) stuffing box top adopts anti-particle to enter the dustproof construction in valve handle activity gap, effectively solves to cause valve cannot normal switch problem because valve rod is stuck.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
Embodiment of the present utility model is described in detail below in conjunction with Fig. 1.
Fig. 1 shows the structural representation of the utility model embodiment.As shown in Figure 1, the utility model provides the wear-resisting discharge valve of a kind of top extending type, comprise flap 1, valve seat 2, valve body 3, guiding rib 4, valve rod 5, gasket seal 6, screw 7, rinse the mouth of pipe 8, Stuffing box 9, dust ring 10, gland 11 and umbrella gear 12, with the flushing mouth of pipe 8 on valve body 3, valve seat 2 is arranged on valve body 3, gasket seal 6 is provided with between valve body 3 and valve seat 2, gasket seal 6 compresses by screw 7 and realizes sealing, the top of valve seat 2 is provided with the flap 1 of top extending type, the unlatching of flap 1 is located by guiding rib 4, valve rod 5 is connected on flap 1, valve rod 5 and Stuffing box 9 contact position are provided with dust ring 10, the pressured cover 11 of dust ring 10 compresses, the keying of valve is rotated handwheel 13 and is driven umbrella gear 12 to realize.
