Abstract
The utility model discloses a pneumatic soft sealed solid particle baiting valve which comprises a valve body (1), a valve cover (2), a valve clack (3), a rocking rod (4) and a valve rod (5). The valve rod (5) is connected with a pneumatic actuator (9) through an adapting piece (8). The valve clack (3) is an assembling unit provided with a rubber sealing ring and a metal clamping ring. The valve body (1) is provided with a gas replacement flange (11). The valve body (1) is provided with a viewing window (10). Because the sealing pair uses materials combined with hard and soft materials, zero leakage of the sealing performance of the pneumatic soft sealed baiting valve can be achieved. In the fully opened to fully closed process of the valve, the phenomenon of blocking and hanging of the solid metal particles are basically eliminated, so as to meet the requirements of working conditions and improve the site safety coefficient. The valve body is provided with viewing windows and each viewing window is arranged on the front and the back of the valve body. The feeding situation in the pipeline can be directly observed. If abnormal conditions appear, the pneumatic soft sealed baiting valve can be timely maintained.
Description
Technical field
The present invention relates to a kind of valve, particularly relate to the metal solid particle dispensing valve that a kind of biological-pharmacy pipeline uses.
Technical background
At present, the metal solid particle dispensing valve that uses at the biological-pharmacy pipeline mostly is floating ball valve, fixing ball valve and V-type ball valve, and the sealing pair of such valve (being valve seat and spherical spool) contacts all the time, easily wearing and tearing; When the complete shut-down position, form simultaneously ring-type from low to high between the sealing pair, in the process of switch, very easily produce the phenomenons such as solid particle card, extension, valve switch was lost efficacy.And the field working conditions pipeline medium is inflammable, explosive and poisonous gas, uses such valve, contacts with the metal solid particle such as gas, and then safety coefficient is very low.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, and provide a kind of favorable sealing property, structural type when medium is the metal solid particle, to be difficult for the Pneumatic soft-sealing solid particle discharging valve that produces card, hangs phenomenon.
Purpose of the present invention realizes by the following technical solutions: Pneumatic soft-sealing solid particle discharging valve, comprise valve body, valve gap, flap, rocking bar, valve rod, described valve rod is connected with pneumatic actuator by link, and described flap is the assembly parts with rubber seal, metal trim ring.Described valve body is with the gas displacement flange.Described valve body is with form.
After adopting structure of the present invention, because sealing pair adopts hard soft material combination, sealability can realize zero leakage; In the process of complete shut-down, the solid metal particle is stopped the phenomenons such as card, extension substantially at valve wide open.Thereby reach working condition requirement, improve the site safety coefficient; Each one of valve body band form front and back can directly be observed reinforced situation in the pipeline, as occur unusually, but on-call maintenance.
Description of drawings
Fig. 1 is the structural representation of Pneumatic soft-sealing solid particle discharging valve of the present invention.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the present invention's workflow diagram in use.
Embodiment
With reference to accompanying drawing 1, Fig. 2, Pneumatic soft-sealing solid particle discharging valve of the present invention, comprise valve body 1, valve gap 2, flap 3, rocking bar 4, valve rod 5 (reaching filler 6, Gland 7), described valve rod 5 is connected with pneumatic actuator 9 (outside valve body) by link 8 (fork-shaped), and described flap 3 is the assembly parts (linking to each other with rocking bar 4) of band (Ethylene Propylene Terpolymer) rubber seal, metal trim ring.Described valve body 1 (under it) is with gas displacement flange 11 (bore DN15/ pressure P N16), with the ducted air of convenient displacement.Described valve body 1 is observed with convenient with form 10 (being each one of front and back).
Described flap 3, rocking bar 4, valve rod 5 link to each other successively; under pneumatic actuator 9 (cylinder assembly) pressure-acting that source of the gas provides at the scene; driving flap by control valve rod work by rocking bar opens or closes; to realize that the automatic standard-sized sheet of valve is to the process of complete shut-down; make the metal solid particle substantially stop the phenomenons such as card, extension; thereby reach working condition requirement, improve the site safety coefficient.
Pneumatic soft-sealing solid particle discharging valve of the present invention is applicable to the brief introduction of biological-pharmacy pipeline operating mode, see accompanying drawing 3: in the chemical industry biopharmaceutical production processes, need to add a kind of solid particle of active metal, illustrate (safety valve is as normally open) to add the lithium material: because lithium material solid particle needs and air insulated, at first closing switch valve 1,2 is opened discharging valve; Replace air in the pipeline this moment, detects and close this solid particle discharging valve after qualified; Add lithium and expect hopper, open switch valve 1, closing switch valve 1 after the lithium material joins in this discharging valve.Replace simultaneously the air in the pipeline, detect qualified after, at first open switch valve 2, then open discharging valve, the lithium material is put in the refinery device is produced; While closing switch valve 2, discharging valve.After adopting Pneumatic soft-sealing solid particle discharging valve of the present invention, the solid metal particle is stopped the phenomenons such as card, extension substantially; Thereby reach working condition requirement, improve the site safety coefficient.
Claims (3)
