Abstract
The utility model relates to a welding set especially relates to be applied to welding set of full welded ball valve valve body. Including lower axle sleeve, go up the axle sleeve, divide half valve and go up and divide half valve down, the upper portion cover of lower axle sleeve have lower minute half valve, the upper portion of half valve of lower branch be equipped with to match with lower minutes half valve and connect minute half valve on, half valve of the supreme branch of last axle sleeve embedding in, half valve of lower branch and last branch half valve in be equipped with the valve, the bottom of half valve of lower branch fix a position mutually through the (gate)wedge, (gate)wedge and lower minute half valve between be equipped with the bed hedgehopping piece, concatenation department of half valve of lower branch and last half valve of branch be equipped with welding bridging plate. Be applied to welding set of full welded ball valve valve body compact structure improves the product quality, promotes operating stability.
Description
Technical field
The utility model relates to a kind of welder, particularly relates to the welder being applied to all-welded ball valve valve body.
Background technology
High head hydraulic turbine water intaking valve selects ball valve usually, because ball-valve structure has high strength and stiffness, can guarantee that high-head hydrogenerator group safely and steadily runs, and there is all-pass runner, flow resistance coefficient is very little, and the pressure loss, close to zero, effectively improves the utilization rate of water energy.
Ball valve body has all-welded structure and flange arrangement two kinds, and at home in design in the past, valve body adopts the blue structure of bisection method mostly, it is relative convenient with installation to process, but the size of ball valve often bigger than normal, valve mass lays particular stress on, and casting quality is difficult to ensure, manufacturing cost is very high.
Utility model content
The utility model mainly solves the deficiencies in the prior art, there is provided a kind of compact conformation degree high, solve in manufacturing uses conventional flanged (FLGD) valve body to cause the defects such as the size of ball valve is bigger than normal, weight lays particular stress on, valve body moulding difficult quality guarantee in the past, improves the quality of unit and the welder being applied to all-welded ball valve valve body of operational reliability.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of welder being applied to all-welded ball valve valve body, comprise Lower shaft sleeve, Upper shaft sleeve, under divide half valve and upper point half valve, the top cover of described Lower shaft sleeve has lower point of half valve, the top of lower point of described half valve is provided with matched upper point half valve with lower point of half valve, described Upper shaft sleeve is embedded in point half valve, valve is provided with in lower point of described half valve and upper point half valve, the bottom of lower point of described half valve is located mutually by wedge, keel is provided with between described wedge and lower point of half valve, the stitching portion of lower point of described half valve and upper point half valve is provided with welded lap plate.
Main feature: by process sleeve with valve body axle sleeve hole location and installation valve, ensures that the axis of valve body and valve is concentric and valve rotation is flexible; Welding procedure, ensures the welding quality of valve body inner and outer welding, reduces the welding deformation of valve body, guarantee welding complete after valve rotate in valve body flexibly, all-welded ball valve structural design can be implemented, reduces weight and the cost of manufacture of ball valve.
The utility model provides the welder and welding procedure thereof that are applied to all-welded ball valve valve body, compact conformation, improves product quality, promotes operation stability.
