Abstract
The utility model discloses a pressurizing cover board device for valve air tightness test, belonging to the range of air tightness test parts. The pressurizing cover board device is formed by that a portal upper frame body is fixedly connected with a portal pressurizing lower frame body table, a cylindrical pin extending out from the head of a hydraulic cylinder is fixed with a hydraulic cylinder connection cap, a pressurizing board connection cap is sleeved on the hydraulic cylinder connection cap and is in threaded connection with a pressurizing board connection base at the center of the pressurizing board, a pressurizing board guide slot is locked on guide rails at two sides of the portal upper frame body, and a movable cover board slides on the portal pressurizing lower frame body table; and a pressurizing movable frame body slides into a slide chute of the portal pressurizing lower frame body table through the sliding rails. By the pressurizing cover board device, the early-stage preparatory work for the air tightness test is omitted, the labor intensity is reduced, the efficiency of the portal pressurizing lower frame body table is improved, and the cost is reduced.
Description
Technical field
The utility model belongs to the air-tight test components range, particularly a kind of cover board arrangement of suppressing that is used for the valve air-tight test.
Background technology
Hydraulic valve, gas valve and vacuum system all have the impermeability requirement with vacuum valve; Before dispatching from the factory, will pass through withstand voltage, air-tight test, when maintenance and inspection, often On line inspection is not too convenient; Must unload down and make air-tight test separately; Because various valve mechanisms are different with specification, need a kind of general valve tightness test device, the utility model is exactly a kind of device that arises at the historic moment.
The utility model content
The purpose of the utility model is that when maintenance and inspection, often the On line inspection air-tight test is not too convenient, the deficiency that does not have common apparatus to use to different with specification owing to various valve mechanisms in the prior art; And a kind of cover board arrangement of suppressing that is used for the valve air-tight test is proposed; It is characterized in that this suppresses cover board arrangement is that gantry upper frame is suppressed the lower frame table top with gantry and is fixedly connected, on the upper frame of gantry by bolt and sealing gasket fixed hydraulic device; The hydraulic oil joint is fixed on the upper end of hydraulic means; The hydraulic cylinder head stretches out straight pin and the hydraulic cylinder attachment cap is fixed, and suppresses the plate attachment cap and is enclosed within on the hydraulic cylinder attachment cap, and be threaded with the plate Connection Block of suppressing of suppressing the plate center; Suppress on the guide rail that the plate guide groove is stuck in upper frame both sides, gantry, removable cover is suppressed on the lower frame table top at gantry and is slided; Suppress movable support body and slip into gantry through slide rail and suppress in the chute of lower frame table top, spacing by stop means.
The said plate plate face central authorities that suppress are provided with the reinforcement welding ring, suppressing on the plate plate face, weld many right-angled trapezium reinforcements from the reinforcement welding ring radially to circumferential edge.
Said suppressing on the plate plate face, mouthpiece is suppressed in two of welding on the pressurizing port on reinforcement welding ring next door.
The beneficial effect of the utility model is originally to suppress the air-tightness check that covering plate structure is applicable to diameter sealed valve between 200-1000mm; The utility model is saved the preliminary preparation of doing air-tight test; Reduce labour intensity, increase work efficiency, reduce cost.
Description of drawings
Fig. 1 is for suppressing the cover board arrangement structural representation.
Fig. 2 is the A-A view of Fig. 1.
Embodiment
The utility model proposes a kind of cover board arrangement of suppressing that is used for the valve air-tight test, below in conjunction with accompanying drawing the utility model is explained.
Fig. 1, shown in Figure 2 for suppressing the cover board arrangement structural representation.This suppresses cover board arrangement is that gantry upper frame 10 is suppressed lower frame 1 table top with gantry and is fixedly connected; On gantry upper frame 10 by bolt 16 and sealing gasket 15 fixed hydraulic devices 17; Hydraulic oil joint 18 is fixed on hydraulic means 17 upper ends; It is fixing with hydraulic cylinder attachment cap 12 that hydraulic cylinder head 14 stretches out straight pin 13, suppresses plate attachment cap 11 and be enclosed within on the hydraulic cylinder attachment cap 12, and be threaded with the plate Connection Block 8 of suppressing of suppressing plate 9 centers; Suppress on the guide rail 7 that plate guide groove 22 is stuck in gantry upper frame 10 both sides, removable cover 5 is suppressed on lower frame 1 table top at gantry and is slided; Suppress movable support body 2 and slip into gantry through slide rail 4 and suppress in the chute 6 of lower frame 1 table top, spacing by stop means 3.Wherein suppress plate plate face central authorities reinforcement welding ring 20 is set,, weld many right-angled trapezium reinforcements 21 radially to circumferential edge from the reinforcement welding ring suppressing on the plate plate face; Mouthpiece 19 is suppressed in two of symmetry welding on the pressurizing port 23 of suppressing reinforcement welding ring 20 next doors on the plate plate face.
This suppresses covering plate structure and is applicable to the action step when diameter sealed valve of model between 200-1000 is done this structure of air-tight test use:
Hang sealed valve on removable cover 5; Promote removable cover 5, make sealed valve suppress plate 9 under; Primer fluid pressure device 17 is placed on the sealed valve to be tested and locking with suppressing plate 9, to prevent interface gas leakage, after air-tight test is accomplished, suppresses plate 9 by hydraulic means 17 liftings; Utilize portable plate 5 to release sealed valves and hang away.The utility model has been saved ring flange with steel plate and sealed valve and has been connected with bolt, nut that (it is the preliminary preparation of doing air-tight test between 16-32 that bolt, nut connect quantity, reduces labour intensity, increases work efficiency, and reduces cost.
Claims (3)
1. cover board arrangement of suppressing that is used for the valve air-tight test; It is characterized in that this suppresses cover board arrangement is that gantry upper frame is suppressed the lower frame table top with gantry and is fixedly connected, on the upper frame of gantry by bolt and sealing gasket fixed hydraulic device; The hydraulic oil joint is fixed on the upper end of hydraulic means; The hydraulic cylinder head stretches out straight pin and the hydraulic cylinder attachment cap is fixed, and suppresses the plate attachment cap and is enclosed within on the hydraulic cylinder attachment cap, and be threaded with the plate Connection Block of suppressing of suppressing the plate center; Suppress on the guide rail that the plate guide groove is stuck in upper frame both sides, gantry, removable cover is suppressed on the lower frame table top at gantry and is slided; Suppress movable support body and slip into gantry through slide rail and suppress in the chute of lower frame table top, spacing by stop means.
