Abstract
The utility model relates to a ball valve used for flow and cutoff of fluid, in particular to a ball valve. Due to the fact that an existing ball valve is usually made of brass rod materials or formed by cast machining and copper pipes are connected through welding, welding efficiency is not high and cold solder joints and desoldering can occur easily during welding. Yellow brass pieces are used in a large number of old type machines so that a transition problem exists. The ball valve comprises a ball valve main body, wherein a yellow brass joint welded and fixed with the ball valve main body is arranged at one end of the ball valve main body; external threads are arranged on the end portion of the yellow brass joint; a through hole communicated with the ball valve main body is arranged on the end face of the yellow brass joint; a liquid adding mouth communicated with the through hole is welded on the yellow brass joint; a red copper connecting pipe is welded at the other end of the ball valve main body; a flare copper nut movably matched with the red copper connecting pipe is arranged on the end portion of the red copper connecting pipe; a port of the red copper connecting pipe extends outward to form a horn mouth; and the flare copper nut is clamped with the horn mouth. The ball valve is simple in structure and convenient to machine, and avoids damage to internal sealing elements due to overheating caused by welding.
Description
Technical field
The utility model relates to a kind of ball valve of blocking or connecting of being used to, and refers in particular to a kind of ball valve.
Background technique
Ball valve is all to present sphere at the inlet/outlet place, thereby blocks mobile.Because ball valve only need revolve the operation that turn 90 degrees and very little moment of rotation just can be closed tight; And the body cavity of opening fully to be medium provide very little, the straight-through runner of resistance; Have suitable directly doing and open and close use, also can be used as the usefulness of throttling and control flow rate.Its compact structure particularly, easy operating and maintenance are applicable to water, solvent, acid and rock gas working medium.
The ball valve main body of existing technology generally adopts brass bar or casting processing to form; Inner dress ball; Then at an end of ball valve main body welding copper pipe, the structure that adopts end cap to add sealing gasket at the other end of ball valve main body is threaded with the ball valve main body and seals, so; Exist welding efficiency not high, and rosin joint and sealing-off appear in welding easily; Simultaneously, what now a lot of old type machine devices were used is brass spare, the transition existing problems.
The model utility content
The technical problem that one, will solve
The purpose of the utility model is that the spy provides ball valve a kind of simple in structure, easy to process to existing in prior technology the problems referred to above.
Two, technological scheme
For solving the problems of the technologies described above; The utility model ball valve includes the ball valve main body, wherein; One end of above-mentioned ball valve main body is provided with and the fixing brazed joint of its welding; The end of this brazed joint is provided with outside thread, and the end face of above-mentioned brazed joint has the through hole that communicates with the ball valve main body, the liquid feeding mouth that welding one communicates with through hole on the above-mentioned brazed joint; The other end of above-mentioned ball valve main body welds a red copper connecting tube, the end of this red copper connecting tube be provided with its movable cooperates receive son, the port of the above-mentioned red copper connecting tube formation horn mouth that stretches out is above-mentionedly received son and horn mouth clamping.
As optimization, the above-mentioned son middle part of receiving has unthreaded hole and the interior threaded hole that communicates, and the diameter of above-mentioned interior threaded hole is greater than the diameter of unthreaded hole, and the above-mentioned son of receiving is plugged on the red copper connecting tube through unthreaded hole, and is rotatably assorted with the red copper connecting tube.
Three, the beneficial effect of the utility model
Simple in structure, easily manufactured, the utility model brazed joint is plugged on an end of ball valve main body earlier; Then fix through welding, then welding liquid feeding mouth on brazed joint has been avoided the welding injury overheated to its sealing elements therein; Receive son and install one additional with the red copper connecting tube is rotatably assorted at the other end of ball valve; This is received son and can be threaded fixingly with other pipe fittings, and simultaneously, horn mouth is with the inclined-plane fitted seal.
