Abstract
The utility model relates to an automatic liquid discharger for a gas tank. The structure comprises a globe, a valve body, and a valve seat insert. The globe is an empty float ball, and the lifting direction of the globe is provided with a shield to make the globe reciprocate in the shield under the buoyancy of liquids so as to realize continuous and automatic liquid discharging and choke sealing. The automatic liquid discharger has the advantages of simple structure, full exhausting, reliable choke, etc. The automatic liquid discharger is quite applicable to the automatic liquid discharger choke valve of the bottom of the buffer tank of iron and steel works.
Description
Technical field
The utility model relates to a kind of gas holder automatic draining device, specifically about a kind of automatic drain choke valve.The utility model is applicable to the draining valve of Iron And Steel Plant knock out drum bottom.
Background technique
At present, on the knock out drum of some Iron And Steel Plant, still use manually-operated drain valve, not only waste of manpower, and cause easily and can not in time close after the unlatching and cause gas leakage, thereby cause security incident.In order to solve the manual operation existing problems, various automatic drain valvings constantly come out, and Chinese patent CN2480664-gas holder automatic draining device is comparatively typically arranged.This patent adopts the magnetic rotary column level meter, test rod, signal conversion module and the air supply processing equipment that are installed on gas holder to form, band magnetic floating drum in the magnetic rotary column level meter moves up and down with the tank level variation, the magnetic switch of installing in the adhesive test rod, switch on or off source of the gas by signal conversion module control double control electromagnetic valve, thereby control is loaded on the pneumatic cut-off valve of liquid-discharging tube under the tank body and opens and closes, realize monitoring discharge opeing automatically, need not special messenger's operation.But its shortcoming is complex structure, be difficult to accomplish not only fully discharge opeing but also air tight.
Summary of the invention
The purpose of this utility model is the shortcoming that exists at prior art, provide a kind of can automatic drain simple in structure, discharge opeing is abundant, the reliable vertical discharge opeing choke check valve of choke.
The technological scheme that realizes the utility model purpose comprises spheroid, valve body, valve seat insert, and spheroid is a hollow float, mainly is to be provided with guard shield on the lifting direction of spheroid.
In above technological scheme, valve body is connected and composed by link by two flanges up and down.
The utility model beneficial effect compared with prior art is to utilize the buoyancy of ball float in liquid, and ball float is moved up and down in guard shield, reaches discharge liquid and choke sealing automatically continuously, and it is simple in structure, exhaust is abundant, choke is reliable.
Description of drawings
Fig. 1 is the structural representation of model utility.
Embodiment
Vertical discharge opeing choke check valve as shown in Figure 1 comprises spheroid 3, valve body, valve seat insert 12, and spheroid 3 is a hollow float, and this hollow float is by the Stainless Steel Ball surface lining nitrile rubber of hollow.Be provided with guard shield 1 on the lifting direction of spheroid 3, guard shield 1 is cylindrical reticular structure, also can adopt porous circular cylinder shape structure, and material adopts stainless steel or plastics.Valve body is connected and composed by bolt 5 and nut 6 by upper flange 4 and lower flange 11.Upper flange 4 adopts with connecting tube 2 and is welded to connect, and connecting tube 2 is by being welded to connect on tank body.The outlet end of lower flange 11 is connected with waste pipe.Valve seat insert 12 adopts the nitrile rubber material, is fitted between upper flange 4 and the lower flange 11.Be provided with trim ring 8 and gasket seal 7 between valve seat insert 12 and the upper flange 4, and be provided with trim ring 9 and gasket seal 10 between the lower flange 11.Be shaped on the sealing surface that cooperatively interacts with spheroid 3 in the middle of the valve seat insert 12.
