Specific embodiment:
As shown in figure 4, being the overall structure figure for being molded ball valve, the injection molding of valve body 1 is completed to be later that one is inseparable in outside
The structure cut has the interface for connecting pipe on valve body 1, and the interface in Fig. 4 is only for illustrating in the left and right sides, at it
In the ball valve of the interface of his form, the present invention can be similarly applicable in.There are the valve rods 2 of exposing to be used at 1 top of valve body in Fig. 4
Handle 6 is connected, the connection type of handle 6 belongs to routine techniques in field and omitted.And it is equipped with inside the middle part of valve body 1
Internal valve gallbladder 4, and in internal valve gallbladder 4 it is valve ball 3.The on-off of ball valve is to rotate valve ball 3 by controlling valve rod 2, makes the hole on valve ball 3
It is connected between the pipeline that hole is connected with valve body 1 and shutdown.
As shown in Figure 1, be molded ball valve sectional view be equipped between valve body 1 and valve ball 3 unlike the prior art
Internal valve gallbladder 4.The inner wall of internal valve gallbladder 4 is matched with 3 outer wall of valve ball and the outer wall of internal valve gallbladder 4 is matched with the inner wall of valve body 1, is referred to interior
Valve gallbladder 4 has the firm form and dimension for being accommodated in the inner valve ball 3, while having the firm shape being contained in valve body 1
And size, and have liquid flow hole between the interface that can enable valve body 1 in the rotation of valve ball 3 by liquid flow hole, the hole of valve ball 3
It communicates.
As shown in Figure 2 and Figure 3, it is a kind of structure that internal valve gallbladder 4 can use, is with valve rod 2 using by internal valve gallbladder 4
Center line is divided into the case where both sides, and in convenient for valve ball 3 to be contained in, the semicircular valve stem port 5 at top is in internal valve
