A kind of optimal technical scheme, the sealing device include sealing shroud and O-ring seals.
A kind of optimal technical scheme, the sealing shroud are nylon material, and the O-ring seals are rubber material.
A kind of optimal technical scheme, the O-ring seals include the first O-ring seals and the second O-ring seals, and described
One O-ring seals are connected to outside sealing shroud and are connected with contiguous block, and second O-ring seals are connected in sealing shroud to be connected with leading screw
Connect.
A kind of optimal technical scheme, states sealing shroud outer wall and is clamped the first O-ring seals equipped with the first ring-type dovetail groove.
A kind of optimal technical scheme, the sealing device are to fix to connect by punching press and contiguous block with leading screw fixing sleeve
Connect.
Leading screw fixation is connected with copper nut using copper nut as leading screw fixing sleeve, copper nut is outer and contiguous block
By Sheet Metal Forming Technology, copper wire mother can be fixedly connected on contiguous block, and connection can have the gap, to play sealing function, in leading screw
Fixing sleeve top is equipped with the sealing shroud of nylon material, and between sealing shroud and contiguous block, sealing shroud and the silk of internal socket
The first O-ring seals and the second O-ring seals are set to play good sealing function between thick stick respectively, in addition, sealing shroud outer wall
The first O-ring seals are put for card equipped with ring-type dovetail groove, firm effect is played in the connection to O-ring seals.
By adopting the above-described technical solution, compared with prior art, the utility model has the advantages that：
Improved on mounting structure for valve, interior fixation is changed to by original outer fixation, adds secondary seal, it is overall to load production
At product inner sealing, this ensure that product exhaustive when reaching certain pressure, alleviates the labor intensity of personnel, improves
Work efficiency, ensure that product quality.
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Brief description of the drawings
