Description
Technical field
The utility model relates to oil shale oil-refining distillation apparatus special valve, is a kind of sealed type push-pull valve.
Background technique
Current domestic oil shale oil-refining gas retort when oil shale ore charging extensive use be push-pull valve.For Fushun type retort, its push-pull valve is made up of valve body, slideway and valve plate, and valve plate both sides are sealing configuration, and valve plate front-end and back-end are non-tight structure.The petroliferous shale disintegrating slag entering slideway during push-pull valve switch can be discharged from valve plate rear and front end, plate energy Long-Time Service.But because valve plate rear and front end is non-tight structure, when destructive distillation furnace roof is malleation from dry stove to external leakage gas, oil gas, cause and run cigarette phenomenon, loss gas, oil gas, befouling environment, and have the potential safety hazard that gas ignition, blast occur.When destructive distillation furnace roof is negative pressure, air bleeds in gas retort from valve plate rear and front end, causes oxygen content in gas, oil gas to increase, cause tile kilning this, oil firing phenomenon,, when oxygen content increases a certain amount of, there is the potential safety hazard that gas ignition, blast occur in loss gas and oil gas.
Summary of the invention
The purpose of this utility model is, put forth effort to solve sealing problem when oil shale retorting furnace roof feeds in raw material and drains semicoke at the bottom of gas retort, at gas retort reinforced or not blank gas when draining semicoke, do not leak gas and oil gas, sealed type push-pull valve rational in infrastructure, sealing reliability is high, use safety, life-span are long.
The purpose of this utility model is realized by following technological scheme: a kind of sealed type push-pull valve, it comprises: valve body, at the middle part of valve body, slideway is set, the valve plate be slidably matched with slideway is built-in with at slideway, one end of valve plate is connected in valve plate seat by connecting pin, valve plate seat and valve rod are connected, it is characterized in that, Seal cage on the right side of valve plate is provided with at the right-hand member of valve body, the right slag dropping tube that on the right side of valve plate, Seal cage lower end is arranged is connected with seal pipe, Seal cage on the left of valve plate is provided with at the left end of valve body, on the left of valve plate, the flange of Seal cage end and stem bearing are connected, stem bearing is built-in with stuffing box packing, stem bearing and stuffing box packing gland are connected, valve plate seat and the valve rod be connected are placed in the Seal cage of left side, its overhanging end is installed in stem bearing and stuffing box packing gland, the left slag dropping tube that Seal cage lower end, left side is connected is connected with seal pipe.
The advantage applies of sealed type push-pull valve of the present utility model exists:
1. because sealed type push-pull valve forms all-sealed structure by Seal cage, stem bearing, stuffing box packing gland and stuffing box packing on the left of Seal cage, valve plate on the right side of valve body, valve plate, valve plate slideway, valve rod, valve plate, and on the right side of valve plate on the left of Seal cage, valve plate Seal cage be all connected with seal pipe, air can not bleed in push-pull valve, gas, oil gas can not from push-pull valve to external leakage;
2. be closely slidably matched between the valve plate of sealed type push-pull valve and slideway, make air, gas, oil gas not by the clearance leakage between valve plate and valve plate slideway;
3. the slag dropping tube of Seal cage connection is equipped with in valve plate arranged on left and right sides, the solid disintegrating slag making plate enter Seal cage when open and close falls into slag dropping tube and discharges, valve plate can be avoided to be blocked by the disintegrating slag entering Seal cage, ensure the normal open and close of valve plate freely, realize long-term normal use;
4. it is rational in infrastructure, and sealing reliability is high, use safety, life-span length etc.
Accompanying drawing explanation
Accompanying drawing 1 is sealed type push-pull valve structural representation.
In figure: in figure: Seal cage, 17 flanges, 18 stuffing box packing on the left of Seal cage, 10 valve bodies, 12 valve plates, 13 slideways, 14 connecting pins, 15 valve plate seats, 16 valve plates on the right side of slag dropping tube, 9 valve plates before slag dropping tube, 8 after 1 valve rod, 2 Glands, 3 stem bearings, 4.
Embodiment
Composition graphs 1 illustrates sealed type push-pull valve of the present utility model.
Sealed type push-pull valve of the present utility model, comprise: valve body 10, at the middle part of valve body 10, slideway 13 is set, the valve plate 12 be slidably matched with slideway 13 is built-in with at slideway 13, one end of valve plate 12 is connected in valve plate seat 15 by connecting pin 14, valve plate seat 15 and valve rod 1 are connected, Seal cage 9 on the right side of valve plate is provided with at the right-hand member of valve body 10, the right slag dropping tube 8 that on the right side of valve plate, Seal cage 9 lower end is arranged is connected with seal pipe, Seal cage 16 on the left of valve plate is provided with at the left end of valve body 10, on the left of valve plate, the flange 17 of Seal cage 16 end is connected with stem bearing 3, stem bearing 3 is built-in with stuffing box packing 18, stem bearing 3 and stuffing box packing gland 2 are connected, valve plate seat 15 and the valve rod 1 be connected are placed in the Seal cage 16 of left side, its overhanging end is installed in stem bearing 3 and stuffing box packing gland 2, the left slag dropping tube 4 that Seal cage 16 lower end, left side is connected is connected with seal pipe.
