Abstract
The invention relates to a ball valve with controller, wherein the nylon ball valve is formed by valve body, valve ball, valve rod, valve cap, handle, sealing ring and O-shaped ring; the valve body is made from nylon; the valve body contains copper liner; the production of nylon ball valve comprises: first, assembling the valve ball, sealing ring and protective sleeve; mounting O-shape ring outside the valve rod; mounting valve rod between the valve ball and protective sleeve, to form the inner element of nylon ball valve; then mounting inner element on the pin axle; mounting positioning sleeve on two sides of inner element; the positioning sleeve is mounted with copper liner and fixed via nut; the floating positioning sleeve sheathes the valve rod; at last, mounting it into mould, then filling nylon. The invention has low cost and long service life.
Description
Affiliated technical field
The present invention relates to the manufacture method of the ball valve of the vertical mechanism of ribbon gymnastics that the domestic water-supply system uses.
Background technique
At present, the ball valve of the vertical mechanism of ribbon gymnastics that uses of known domestic water-supply system all is the copper ball valve.For example: 200420038487.4 " a kind of ball valve spheroids " have announced that spheroid " can utilize materials such as toughened plastic, nylon." 200310116736.7 " ball valves that five position improvement are arranged in the valve " disclose " ball valve body in sealing gasket all be the Nylon manufacturing ".But the nylon ball valve that does not also have valve body and valve rod to adopt nylon to make.The disadvantage of copper ball valve is that the cost of raw material is higher, and manufacturing expense is higher, and working life is shorter.
Summary of the invention
In order to overcome the deficiency of existing domestic water-supply system with above-mentioned three aspects of the vertical mechanism of ribbon gymnastics ball valve, it is lower to the invention provides a kind of cost of raw material, and manufacturing expense is lower, nylon ball valve and manufacture method thereof that working life is long.
The technical solution adopted for the present invention to solve the technical problems is: a kind of manufacture method of nylon ball valve: at first valve ball, seal ring and sheath are fitted together, again O shape circle is contained in the outside of valve rod, and valve rod is contained between valve ball and the sheath, be combined into the endosome of a nylon ball valve; Secondly endosome is contained on the mandrel, loads onto setting sleeve, copper bush is housed in the setting sleeve, fix with nut again, and the setting sleeve that will float is enclosed within the outside of valve rod in the both sides of endosome; At last it is contained in the mould, injects nylon material.
The invention has the beneficial effects as follows: the cost of raw material is lower, and manufacturing expense is lower, and working life is longer.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is a product plan view of the present invention.
Fig. 2 is a manufacture method schematic representation of the present invention.
Among the figure: 1, valve body, 2, bonnet, 3, valve rod, 4, handle, 5, nut, 6, mandrel, 7, setting sleeve, 8, seal ring, 9, valve ball, 10, O shape circle, 11, the setting sleeve that floats, 12, sheath, 13, copper bush.
Embodiment
In Fig. 1～2, a kind of nylon ball valve is by valve body 1, be contained in the valve ball 9 in the valve body 1, be contained in the valve rod 3 on the valve ball 9, be fixed on handle 4 on the valve rod 3 with bonnet 2, be contained in the seal ring 8 between valve body 1 and the valve ball 9, the O shape circle 10 that is contained between valve body 1 and the valve rod 3 is formed.Valve body 1 usefulness nylon is made.In the valve body 1 copper bush 13 can be arranged, also can not have copper bush 13.Copper bush 13 is tapped.
In Fig. 1～2, a kind of manufacture method of nylon ball valve at first fits together valve ball 9, seal ring 8 with sheath 12, O shape circle 10 is contained in the outside of valve rod 3 again, and valve rod 3 is contained between valve ball 9 and the sheath 12, is combined into the endosome of a nylon ball valve.Secondly endosome is contained on the mandrel 6, loads onto setting sleeve 7 in the both sides of endosome; In the setting sleeve 7 copper bush 13 can be housed, can not adorn copper bush 13 yet, the setting sleeve 7 of dress copper bush 13 does not have outside thread, and the setting sleeve 7 of not adorning copper bush 13 has outside thread; Fixing with nut 5 again, and the setting sleeve 11 that will float is enclosed within the outside of valve rod 3.Endosome with belt carcass axle 6 is contained in the mould at last, injects nylon material.After injection moulding is finished, the endosome of belt carcass axle 6 is taken off from mould, pull down nut 5, take out setting sleeve 7, setting sleeve 11 and mandrel 6 float.If copper bush 13 is housed in the setting sleeve 7, nylon ball valve is just made and has been finished so; If do not adorn copper bush 13 in the setting sleeve 7, so, when withdrawing from setting sleeve 7, also just produced the internal thread of nylon ball valve.
