Abstract
The utility model discloses a kind of protectives using supersonic spray coating to carve type valve valve plate, and it includes valve plate matrix that this, which carves type valve valve plate,（1）, it is characterized in that：In valve plate matrix（1）Metallic sealing section on cover supersonic spray coating hard alloy layer（2）, valve plate matrix（1）Bottom pass through holding screw（4）Elastic protective cushion is installed（3）；Elastic protective cushion（3）Top exterior angle use fillet, both ends of the surface are consistent with valve plate end face keeping parallelism.The utility model is simple in structure, it is easy to process, production cost will not improve, and not only can effectively be protected in operation process, improve sealing effect, moreover it is possible to it is effective prevent sealing surface of valve plate in by work condition environment the corrosion, wears such as corrosive gas, fluid and husky large particle cause to leak, further increase valve base seal property, the maintenance period of valve is extended, product service life is improved, improves complete machine working efficiency.
Description
Technical field
The utility model is related to electric power, oil, chemical industry, metallurgy, mining, sewage disposals etc. with carving type valve, and in particular to one
Kind carves type valve valve plate.
Background technology
Valve plate is that the indispensable sealing of type valve valve is carved in electric power, oil, chemical industry, metallurgy, mining, sewage treatment field
One of component, wherein the front end for carving type valve valve plate mostly does not have protective device, sealing surface to be handled using hard alloy overlay welding；But
Since weld deposit process medium temperature is spent high and concentrates, it be easy to cause the properties of product such as the deformation of valve plate matrix corresponding position, mechanical performance
Decline；And since built-up welding is influenced by factors such as temperature, speed, the hardness of overlay cladding cannot keep uniformity, always exist
The point that hardness differs is generated on sealing surface so that valve plate scratches matched valve seat during the work time, causes to leak；And one
As carve type valve valve plate directly use angle design, front end does not carry out protective treatment, valve plate top and valve is caused in assembling process
Seat collision, forms scuffing of colliding with, influences valve seal performance, shorten the replacement cycle of valve, reduces efficiency.
Invention content
The purpose of this utility model is that：A kind of protective using supersonic spray coating is provided and carves type valve valve plate, valve plate is close
Cover uses supersonic spray coating hard alloy layer so that sealing surface of valve plate hardness is uniform, and the porosity is extremely low, prevents because of individual places
Hardness unevenness to generate scratch in valve plate valve seat operational process, avoids seal leakage, reduce due to rotten in working environment
The whirlpool of the generations such as corrosion gas, liquid corrodes, and further increases sealing effect, extends the maintenance period of valve plate valve seat, is passing through
Reach best sealing effect after crossing fine-grinding and polishing, improves the working efficiency of complete machine equipment.
The utility model use technical solution be：It includes valve plate matrix that this, which carves type valve valve plate, it is characterized in that：In valve
Supersonic spray coating hard alloy layer is covered on the metallic sealing section of plate matrix, bullet is installed in the bottom of valve plate matrix by holding screw
Property protective pad.
Wherein, the top exterior angle of elastic protective cushion uses fillet, both ends of the surface consistent with valve plate end face keeping parallelism.
In work, valve plate is first contacted by elastic protective cushion with sealing surface of seat in operation, is slowly moved to the super of valve plate
Velocity of sound coated with hard alloy-layer seals.
The utility model has the following advantages：1. simple in structure, easy to process, production cost is low, and valve plate valve seat is avoided to transport
Metallic matrix direct collision in row reduces the probability that sealing surface generates scuffing of colliding with, improves the sealing performance of valve plate valve seat；2.
The sealing intensity of supersonic spray coating hard alloy layer is high and hardness is uniform, wear resistant corrosion resistant, and no too low phenomenon of excessive high hardness is whole
The hardness of hard alloy layer is up to HV >=1450, and the integral sealing face porosity is minimum, uniform, and the sealing surface porosity passes through sealing of hole
It can reach≤0.3% after processing, greatly reduce the probability of whirlpool corrosion, extend the maintenance period of valve plate, improve complete machine work effect
Rate；3. using supersonic spray coating hard alloy layer, and sealing surface passes through sealing pores, sealing surface integral strength height, abrasion-proof corrosion-proof
Erosion, is not likely to produce abrasion so that sealing effect is more preferable；4. valve plate front end uses elastic protective cushion so that valve seat is first anti-with elasticity
Protection pad contacts, and is slowly moved to sealing surface of valve plate, and valve plate is avoided since mobile front end bumps to valve seat, to subtract during the work time
Scuffing of colliding with is generated between few valve plate valve seat, the sealing performance of valve plate valve seat is also accordingly improved, extends the maintenance of valve plate valve seat
Period improves complete machine working efficiency.
Description of the drawings
Fig. 1 is the structure chart that the utility model carves type valve valve plate using the protective of supersonic spray coating.
In figure：1 valve plate matrix, 2 supersonic spray coating hard alloy layers, 3 elastic protective cushions, 4 holding screws.
Specific implementation mode
As shown in Figure 1, it includes valve plate matrix 1 that this, which carves type valve valve plate, it is characterized in that：In the metallic sealing section of valve plate matrix 1
The bottom of upper covering supersonic spray coating hard alloy layer 2, valve plate matrix 1 elastic protective cushion 3 is installed by holding screw 4.
Wherein, the top exterior angle of elastic protective cushion 3 uses fillet, both ends of the surface consistent with valve plate end face keeping parallelism.
When work, valve plate matrix 1 is contacted by elastic protective cushion 3 with valve seat, and pass through elasticity during moving down
The miniature angular extrusion of protective pad 3 is moved to supersonic spray coating hard alloy layer 2, reaches expected operating position and is sealed work
Make.
