Abstract
The utility model relates to a sealed gate valve, particularly a floating sealed gate valve used for a reciprocating piston conveying pump. The utility model aims to provide a novel floating sealed gate valve used for a reciprocating piston conveying pump with the advantages of light weight, less parts, simple processing technology, good sealing performance, convenient assembly and maintenance, high sucking and pumping efficiency and long pumping distance in order to overcome the disadvantages of the existing gate valve having poor sealing performance, difficult maintenance and replacement, etc. The utility model comprising a valve core set is characterized in that the valve core set is composed of blind valve cores, a straight through valve core and valve core sleeves, wherein, the straight through valve core is arranged between the two blind valve cores, elastic elements are arranged between the straight through valve core and the valve core sleeves as well as between the blind valve cores and the valve core sleeves, and the inner surfaces of the blind valve cores and the straight through valve core are provided with wearproof welding layers. The utility model is mainly used for concrete conveying pumps and sludge pumps.
Description
Technical field
The utility model relates to a kind of seal gate valve, specifically, relates to the floating seal gate valve that a kind of reciprocating piston transfer pump is used.
Background technique
At present, the valve that is used for concrete pump has S cast distributing valve and oblique installing type gate valve, the former advantage is a good airproof performance, shortcoming is that the amount of parts that is connected with valve body is more, the requirement on machining accuracy height, the processing technology complexity, valve body recasting causes high, assembling, maintenance, replacing be difficulty, and adaptability is relatively poor; The latter's advantage is that transfer speed is fast, the inhalation rate height, shearing force is big, stronger to different gradation quality concrete adaptability, shortcoming is that sealing is relatively poor, and it is poorer to satisfy the seal request of charging and discharging end different direction, particularly spool (flashboard) wearing and tearing back sealing, pumping efficiency obviously reduces, and has a strong impact on the pumping distance.
Summary of the invention
The purpose of this utility model is to provide a kind of weight lighter, number of spare parts is less, processing technology is simple, good seal performance, the assembling maintenance is more convenient, can improve suction again, pump efficient, the floating seal gate valve that the novel reciprocating piston transfer pump of raising pumping distance is used is to overcome above-mentioned shortcoming.
For achieving the above object, the technical solution that the utility model adopts is formed 1 gate valve by 2 blind spools and 1 straight-through spool, 2 blind spools are respectively applied for closing of charging and discharging mouth, and can utilize material that the pressure of its generation is increased sealability, 1 straight-through spool then is used for the unlatching of charging and discharging mouth, and valve core housing is arranged outside spool, under the elastic element effect, spool and valve core housing are in quick condition, and energy is the gap of compensate for wear generation automatically, thereby guarantee sealability.
The utility model comprises the spool group, it is characterized in that this spool group by blind spool 9,9 ', straight-through spool 11 and valve core housing 6 are formed, described straight-through spool 11 blind spool 9 and 9 ' between, described blind spool 9,9 ' and valve core housing 6 between, between straight-through spool 11 and the valve core housing 6, be equipped with elastic element 7, described blind spool 9,9 ' and the internal surface of straight-through spool 11 wear-resisting layer 12 is arranged.
Described elastic element 7 is spring or other elastic materials.
The beneficial effects of the utility model are that this novel floating seal gate valve has in light weight, cost is low, assemble easy to maintenance, good seal performance, especially the gap that can compensate for wear produces keeps excellent sealing performance, improves to suck, pump efficient, improve the pumping distance, select for use hard alloy seal ring to increase the service life.
Description of drawings
Accompanying drawing is a structural representation of the present utility model, wherein, and 1-delivery pipe, 2-valve gland, 3-hard alloy seal ring, 4-O type rubber seal, 5-slip planker, 6-valve core housing, 7-elastic element, 8-binder case, 9,9 '-blind spool, 10-binder cylinder, 11-leads directly to spool, the wear-resisting layer of 12-.
Embodiment
Below in conjunction with accompanying drawing the utility model and embodiment thereof are described in further detail.
Referring to accompanying drawing, situation when the diagram spool is in the pumping material, binder cylinder 10 is communicated with delivery pipe 1 through straight-through spool 11 by binder case 8, along with binder cylinder 10 inner carrier left lateral, the material that is stored in binder case 8 and the binder cylinder 10 is pumped to conveyance conduit 1, realize pumping, binder case 8 and valve core housing 6, under the active force of elastic element 7, realize sealing between straight-through spool 11 and the valve gland 2, the blind spool 9 of feed end ' suffered material active force is consistent with elastic element 7 force directions in addition, further improved and valve gland 2 between sealing, discharge end valve core housing 6 is in off working state with blind spool 9; Pumping stops, slip planker 5 drives the spool group under external force and moves on fast, straight-through spool 11 is in feed end, material feeding mouth is opened, discharge end is closed, binder cylinder 10 inner carrier right laterals, material is inhaled into binder case 8 and binder cylinder 10, be in the straight-through spool 11 and valve gland 2 of material feeding mouth, under the elastic element active force, realize sealing between valve core housing 6 and the binder case 8, be in the blind spool 9 and binder case 8 of discharge end, under the active force of elastic element, realize sealing between valve core housing 6 and the valve gland 2, in the blind spool 9 suffered delivery pipes of discharge end material and piston right lateral to the force direction of generation consistent with the elastic element force direction, further improved its sealability; When the termination of piston right lateral, slip planker 5 drives the spool groups and moves down fast, and the spool group is got back to shown position, promptly enters pumping material situation; At blind spool 9,9 ' and straight-through spool 11 internal surface build-up wear-resistant layers 12, utilize the power of slip planker 5 to implement effectively cutting to granular material, can fully guarantee the selfsealings performance of floating seal gate valve; Change diagram charging and discharging mouth position as need, blind spool 9,9 ' anti-dress is got final product.
