Embodiment 1

[0044] Refer to attached Figure 1~4 with Figure 8 : A forced seal ball valve, comprising a ball base 2, a disc 4 and a stud gear 1, the stud gear 1 is mounted on the ball base 2 through a stud gear shaft 11, one side of the stud gear 1 passes through a The threaded boss is threadedly connected to the valve clack 4, and more than two positioning holes 10 are correspondingly opened on the contact end surfaces of the valve ball base body 2 and the valve clack 4, and limit pins are installed in the positioning holes 10. The stud gear 1 is connected with the valve stem gear 15 sleeved on the valve stem 14 through the pinion 3 .

[0045] The utility model relates to a valve ball assembly tool for a forced sealing ball valve, which includes a vertical guide pin and a limit support. The guide pin is provided with a limit support outside, and the top of the guide pin is provided with a rotating part. The guide pin is a sleeve guide pin 5, including a screw 501 and an outer wire sle...

Embodiment 2

[0058] Refer to attached Figure 5 : The rotating part at the top of the top screw 501 in the guide pin is connected to the transmission mechanism, and the transmission mechanism includes the driven gear 6 of the top screw installed on the rotating part and the driving gear 7 meshing with it, and the driving gear 7 is installed on the output shaft of the stepping motor 8 On, the stepper motor 8 is installed on one side of the outer thread sleeve 502. After the steps in step 5 are completed, use the stepping motor 8 and the transmission mechanism to connect the guide pins through the transmission mechanism, and synchronously control the inner jacking wires 501 of the guide pins 501 in the multiple positioning holes 10 to rotate synchronously through the stepping motor 8, so as to lower the position synchronously. The height of the disc support 503 .

[0059] The guide pins are also available in a more automated design driven by stepper motors. Adjust the 3 guide pins to the s...

Embodiment 3

[0061] Refer to attached Image 6 with 7 The guide pin is a stepped guide pin 9, the stepped guide pin 9 includes a cylindrical guide pin body and a plurality of step limit supports 901 arranged on the guide pin body, and the plurality of step limit supports 901 are arranged in a stepped ring on the guide pin On the outside of the body.

[0062] Image 6 , 7 As shown, the guide pin can also adopt an integrated structure with a preset step height. After the stepped guide pin 9 is inserted into the positioning hole 10, as in the first embodiment, the notch of the valve flap 4 is aligned with the stepped guide pin 99, and the valve flap 4 is lowered. Firstly, the step limit support 901 at the highest position is used to support the disc 4. At this time, the thread of the disc 4 is just in contact with the roller 12, and the coincidence of the threaded shaft of the disc with the stud gear shaft 11 and the verticality of the disc 4 are all controlled. Well bound. Rotate the 3...

Abstract

The invention relates to a forced seal ball valve and ball valve assembly fixture and an assembly method, and belongs to the technical field of seal valves. The force seal ball valve and valve ball assembly fixture includes a vertical guide pin and a limiting support, and the outside of the guide pin is provided with the limiting support. The assembly method includes the following steps of 1) forming positioning holes; 2) mounting double-screw bolt gears (1); 3) installing a pin roller mechanism in a sleeve mode; 4) installing a positioning fixture and pointing the limiting support toward theaxis direction of a double-screw bolt gear shaft (11); 5), lifting valve clacks (4), and contacting the bottom surfaces of the valve clacks (4) with the limiting support arranged on the guide pin; 6),vertically screwing the valve clacks (4) in; 7), fully screwing the valve clacks in until the valve clacks are tightened with a valve ball base (2), taking out the guide pin, and placing a limiting pin in a guide pin hole. It takes only several minutes or even tens of seconds to assemble a seal valve using the assembly method, which saves a lot of assembly time, assembly process is simple and easy to operate, and a lot of production costs are saved.

Description

technical field [0001] A forced sealing ball valve, a valve ball assembly tool and an assembly method belong to the technical field of sealing valves. Background technique [0002] The forced sealing ball valve has a series of advantages such as compact structure, reliable sealing, long service life, and rapid action, such as the technical solution recorded in a forced sealing ball valve disclosed in Chinese patent CN105927750A, but the disc of this type of sealing ball valve is in the The process of installing it on the ball base is not easy. [0003] The basic action principle of this type of forced sealing ball valve is that the valve stem simultaneously drives the valve ball and the gear transmission system to complete the 90-degree rotation of the valve ball assembly synchronously. After the valve ball is in the closed position, the valve stem will only drive the gear transmission system. Finally, through the helical constraint relationship between the stud gear and th...
