Abstract
The utility model relates to the technical field of a slurry valve, in particular to an elastic flashboard of the slurry valve. The elastic flashboard is characterized in that the flashboard is H-shaped, two sides of the flashboard are provided with hard seal, and soft seal is arranged outside the hard seal. Compared with the prior art, the hard seal and the soft seal are combined to protect the flashboard, thereby integrating advantages of the two different seal; the elastic flashboard can be more high temperature resistant, high pressure resistant and corrosion resistant compared with the former flashboard only adopting the hard seal or the soft seal; moreover, the elastic flashboard can generate slight deformation to make up for the deviation of the seal face angle caused during working process, so that the sealing property of the elastic flashboard can be greatly improved.
Description
Technical field
The utility model relates to the slurry valve technical field, specifically a kind of Flexible disc of slurry valve.
Background technique
Parallel Slide Valves has good shearing by effect, be most appropriate to unmanageable fluids such as slurry, powder material, fiber, slurries, cement mortar, sewage treatment, be widely used in industries such as papermaking, petrochemical industry, mine, draining, food, also can use slurry valve in a large number in the industries such as more domestic oil, chemical industry, metallurgy.Yet most slurry valve flashboard under this abominable industrial and mineral condition, can corrode because certain situations such as the high temperature of flowing medium, high pressure cause the flashboard distortion for a long time, causes valve body to damage.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of Flexible disc that can resist the slurry valve of high temperature, high pressure, corrosion to be provided, and has solved that flashboard in the slurry valve is yielding, the problem of corrosion.
Designed a kind of Flexible disc of slurry valve to achieve these goals, it is characterized in that: this flashboard is a H type flashboard, and the both sides of described flashboard have hard sealing, and also has soft seal outside hard sealing.
The utility model is compared with prior art, and the mode that has adopted hard sealing to combine with soft seal is protected flashboard, has gathered the advantage of two kinds of different sealings, than only more high temperature resistant, high pressure resistant, corrosion-resistant with hard sealing or soft seal in the past; And this Flexible disc can produce micro-deformation, remedies the deviation that the sealing surface angle produces in course of working, and its sealability is improved greatly.
Description of drawings
Fig. 1 is the utility model structural representation.
Referring to Fig. 1,1 is flashboard; 2 is hard sealing; 3 are soft seal.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
Be illustrated in figure 1 as the utility model structural representation, the flashboard 1 of this slurry valve is a H type flashboard, and the both sides of described flashboard seal 2 with hard, and seals outside 2 also with soft seal 3 hard.Hard sealing 2 has the advantages that to reduce fluid resistance, can allow the flow direction of medium not limited, flow-disturbing not, but because of flashboard is immersed in the flowing medium for a long time, may cause hard sealing material to corrode, so hard sealing 2 direct contact mediums have so just been avoided in attached again one deck soft seal 3 outside hard sealing sealing 2.The structure of the additional two-layer sealing of this H type flashboard has constituted a kind of Flexible disc of favorable sealing property, can produce micro-deformation and remedy the deviation that the sealing surface angle produces in course of working, not only solved hard sealing 2 problem of corrosion easily, also further improved the sealability of slurry valve, made the work that valve can be more stable.
Claims (1)
1. the Flexible disc of a slurry valve, it is characterized in that: this flashboard is a H type flashboard, the both sides of described flashboard are with hard sealing, and also have a soft seal in that hard sealing is outer.
