no. 1 example

[0028] Please check figure 1 and figure 2 , a multi-style ball valve, including a body 1, a valve ball 2, a valve stem 3 with inner and outer ends, a handle 4, two anti-diarrheal rings 5 ​​and a connecting sleeve 6.

[0029] The main body 1 is provided with a flow passage 11 running through the front and back and a mounting hole 13 passing through the inside and outside of the flow passage 1 . The flow channel 11 has a front section 111 and a rear section 112 , a step surface 113 facing forward is formed between the front section 111 and the rear section 112 , and an internal thread is provided on the front part of the inner hole of the front section 111 . The anti-diarrheal ring 5 and the valve ball 2 are located in the flow channel 11, and the valve ball 2 can be rotatably positioned between the two anti-diarrheal rings 5. The outer rotary surface of the connecting sleeve 6 is provided with external threads, and the connecting sleeve 6 is screwed to the inner hole of the ...

no. 2 example

[0035] Please check image 3 and Figure 4 , it is different from the first embodiment in that: the inner hole of the connecting sleeve 6 and the inner hole of the rear section 112 are set to the same connection structure 7, in this embodiment, the connection structure 7 is an internal thread, and the external pipe does not pass through The extension joint is connected to the inner hole of the connecting sleeve and the rear section, and the external pipe is directly connected to the inner hole of the connecting sleeve and the rear section. The external pipe with external thread can be directly connected to the ball valve through screw connection.

no. 3 example

[0037] Please check Figure 5 and Figure 6, It differs from the second embodiment in that: the connecting structure 7 of the inner hole of the connecting sleeve 6 and the inner hole of the rear section 112 is a socket structure. The external pipe can be directly connected to the ball valve through the socket structure.

Abstract

The invention discloses a multi-style ball valve. The ball valve comprises a body, a valve ball, a valve rod, a handle, two checking rings, a rotation limit sleeve and a connecting sleeve, wherein the body is provided with a flow path and a mounting hole; the checking rings and the valve ball are located in the flow path, and the valve ball can be rotatably located between the two checking rings; the valve rod is connected with the valve ball, and the handle is connected with the valve rod and rotates to drive the valve ball to rotate through the valve rod so as to control the flow path; the flow path is provided with a front section and a back section, and a forward step surface is arranged between the front section and the back section; the connecting sleeve is arranged at the front section to locate the two checking rings and the valve ball between the shaft end of the connecting sleeve and the step surface; and an inner hole of the connecting sleeve and an inner hole of the back section are in the same connecting structures capable of connecting external pipes. The ball valve has the advantages that the inner hole of the connecting sleeve and the inner hole of the back section are in the same connecting structures capable of connecting external pipes, the ball valve and the external pipes are connected conveniently, firmly and reliably, the sealing performance is high, parts are few, and the cost is low.

Description

technical field [0001] The invention relates to a multi-style ball valve. Background technique [0002] Existing ball valves, such as "a valve device" previously applied by the applicant, include a body, a valve ball, a valve stem, a handle, a lining, two anti-diarrheal rings, two pipe joints and two nuts . The body is provided with a flow channel through the front and back and a mounting hole through the inside and outside of the flow channel; the anti-drainage ring and the valve ball are located in the flow channel, and the valve ball can be rotated and positioned between the two anti-drainage rings; the valve stem can be rotated and sealed Installed into the mounting hole and the inner end is connected to the valve ball, the handle is connected to the outer end of the valve stem, and the rotation of the handle drives the valve ball to rotate through the valve stem to control the flow path. The liner is connected to the flow passage to locate the two valve seats and the ...
