Raising and quality cannot be ensured.
Utility model content
The utility model is directed to the problems referred to above, overcomes deficiency, it is proposed that a kind of ball valve.Ball valve is in whole injection cladding process
In, valve stem seal part, will not be anti-so as to reach because of the performance of the sealing ring of high temperature valve rod all outside Overmolded
The function of high temperature product, realizes the raising of productivity effect and quality.
The technical scheme that the utility model is taken is as follows：
A kind of ball valve, including：
Valve body, including hollow body and the bonnet that is threadedly coupled with body, the side wall of body has hollow control
Portion, the inner space of control unit connects in space in vivo with this, and the control unit includes the injection area of adjacent body and away from this
The non-injection area of body；
Valve element, installed in this in vivo；
The valve rod of lengthening, on control unit, one end of valve rod is stretched in body and is coordinated with the valve element, the valve rod
Coordinate with the sealing of control unit madial wall, and seal at cooperation positioned at non-injection area；
Injection molded layers, are coated on the outer surface that body, bonnet and control unit are molded area.
The valve rod that ball valve is lengthened by design so that non-injection area is located at valve rod and control unit sealing cooperation, whole
During injection cladding, the performance of encapsulant at cooperation will not be sealed because of high temperature valve rod and control unit, so as to ensure
There is preferable sealing property；This version of ball valve can reach effect that high temperature-proof destroys product, realize productivity effect
And the raising of quality.
Optionally, lateral wall of the injection area adjacent to non-injection area is provided with annular groove.
The contact area of injection molded layers and control unit can be increased by arranging annular groove, it is ensured that the reliability of cladding.
Optionally, the valve element is hollow spheroidal structure, and valve element has the opening being oppositely arranged, and described in vivo
Two plastics springs are installed, each plastics spring is respectively positioned at the both sides of valve element.
Optionally, the bonnet is tightly connected by sealing ring with body.
Optionally, the valve rod is coordinated by some sealing rings with control unit sealing.
Optionally, the handle being connected with valve body outer end is also included.
Optionally, also including the trim being set on control unit.
The beneficial effects of the utility model are：The valve rod that ball valve is lengthened by design so that valve rod is matched somebody with somebody with control unit sealing
Positioned at non-injection area at conjunction, during whole injection cladding, will not seal at cooperation because of high temperature valve rod and control unit
The performance of encapsulant, so as to ensure there is preferable sealing property；This version of ball valve can reach high temperature-proof destruction
Effect of product, realizes the raising of productivity effect and quality.
