Abstract
Disclosed is an anti-reverse-flow liquid concentration proportion device which comprises a shell, an inner lining body arranged inside the shell, a joint welded outside the shell, a connecting pipe connected with the joint, an orifice, a dynamic body, a linkage rod, a static body and a ring mat arranged inside the connecting pipe, a sealing layer arranged between the shell and the inner lining and a pressure gauge arranged on the shell. The utility model can effectively prevent the reverse flow of the mixed liquid to prevent accidents and can indicate at site or transmit the reverse flow signal from the remote.
Description
Technical field
The utility model relates to a kind of strength of fluid proportioner, especially anti-backflow strength of fluid proportioner.
Technical background
At present, in the concrete technology of the production process of industries such as chemical industry, thermoelectricity, extensively need with continuous and stable concentration liquid, preparation method commonly used after adopting injector that two kinds of stoste fluids are mixed, sprays continuously.And most of mixed liquors do not allow to flow backwards back in a certain stoste, otherwise can have an accident.
Existing concentration proportion device, typical structure are that the grant number of Chinese patent is the steel bushing tetrafluoro injector shown in the CN 2468606Y.Its shortcoming is: (1), can not prevent that mixed liquor from flowing backwards; (2), the interference fit between steel bushing and the liner tetrafluoro makes processing cost higher; (3), no pressure gauge, can not indicate the duty of vacuum chamber, the diagnosis of unfavorable accident condition.
Summary of the invention
For overcoming the deficiency of existing strength of fluid proportioner, the utility model provides a kind of anti-backflow strength of fluid proportioner, prevents the production safety accident and the inefficacy of technology purpose of flowing backwards and causing because of mixed liquor.
The anti-backflow strength of fluid proportioner that the utility model provides contains the carbon steel pipe shell, is satisfied with inner lining body, the female adapter that is welded in shell, the adapter that links to each other with joint in the shell and is loaded on orifice plate, kinetoplast, connecting rod, quiet body in taking over, encircles sealant between pad, shell and the liner, is satisfied with Pressure gauge and adapter thereof on the shell.One end of described adapter and joint are to be threaded; Described orifice plate is a cylinder, and there are several axially extending bores the centre, and its aperture is littler than kinetoplast; Described quiet body is made of nonmetal, and a coaxial reducing through hole is arranged in it, and two holes link to each other with the cone face; Described kinetoplast be one the band connecting rod spheroid, be positioned at orifice plate and quiet body formation the space, but under the qualification of the connecting rod that is attached thereto axially reciprocating, when moving to the conical surface of quiet body, form linear sealing; Described ring pad is the air ring that is made of nonmetal, the part of its external diameter and adapter one end inwall interference fit, another part flange of external diameter; Described sealant can be the coagulated colloid that resin constitutes, and therefore can remove the boring process of display pipe inwall; Described Pressure gauge can be electric contact pressure vacuum gauge or conventional vacuum table, both can indicate the pressure of mixing chamber on the spot, but the teletransmission signal of telecommunication again.
Anti-backflow strength of fluid proportioner of the present utility model is work like this:
The high pressure solvent from the main flow section through mixing chamber, high fast direction mixer, mixing chamber forms negative pressure simultaneously, the kinetoplast that communicates with mixing chamber is promptly opened under negative pressure, solute is inhaled into mixing chamber from the tributary section, solvent, solute under the pressure of solvent, are penetrated from proportioner through mixer, diffuser and to be entered process equipment after mixing chamber mixes.After process equipment manipulation occurred unusually, process equipment pressure raise, and caused mixed liquor to flow backwards.Because the pressure of solvent is far above the pressure of solute, mixed liquor will flow backwards to the tributary section through the mixing chamber of proportioner, at this moment, kinetoplast conical surface to quiet body under the effect of malleation and connecting rod moves, the sphere of kinetoplast and the conical surface of quiet body form linear sealing at once, mixed liquor is obstructed and flows backwards and do not return the tributary section and the solute system that communicates thereof at this, has prevented the generation of accident.
Under the unusual situation of process equipment, the proportioner mixing chamber pressure can become malleation by negative pressure, and the Pressure gauge that communicates with mixing chamber can show immediately, and signal is reached in other warning or the robot control system(RCS).
Effect of the present utility model is significantly, at first is can avoid effectively because the accident that the mixed liquor refluence occurs, and can in time sends the refluence signal; Next is the boring process processing of having removed the outer steel shell inwall, has saved processing cost.

The specific embodiment
The anti-backflow strength of fluid proportioner of this specific embodiment, the inner lining body of contain the carbon steel pipe shell, being satisfied with to make with tetrafluoro in the shell, be welded in steel female adapter on the shell, the steel that links to each other with joint takes over and is loaded on tetrafluoro in taking over and make orifice plate, spherical kinetoplast, connecting rod, quiet body, encircle epoxy sealing layer between pad, shell and the liner, be satisfied with electro connecting pressure gauge and adapter thereof on the shell.The end that described steel is taken over and joint are to be threaded.Described orifice plate is the thick tetrafluoro cylinder of 5mm, and there are 4 Φ 6mm axially extending bores the centre, and its aperture is littler than kinetoplast.Described quiet body is made of tetrafluoro, and a coaxial reducing through hole is arranged in it, Φ 40mm and Φ 12mm, and two holes link to each other with the cone face.Described kinetoplast is made the spheroid Φ 16mm of a band connecting rod by tetrafluoro, one end of connecting rod links to each other with spheroid, the other end inserts in the mixer and play the guiding role, be positioned at the space that orifice plate and quiet body form, but axially reciprocating under the qualification of the connecting rod that is attached thereto, form linear sealing when moving to the conical surface of quiet body, when moving to orifice plate, work is promptly opened in sector hole road, tributary.Described ring pad is the air ring of being made by tetrafluoro, the part of its external diameter and adapter one end inwall interference fit, another part flange of external diameter.What described sealant was used is the coagulated colloid that epoxy resin is made, and therefore can remove the boring process of display pipe inwall.Described Pressure gauge is the electric contact pressure vacuum gauge, both can indicate the pressure of mixing chamber on the spot, but the teletransmission signal of telecommunication again.
