Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Figure 1, the present invention includes right valve barrel 1, spheroid 2, handle 9 and left valve barrel 12, right valve barrel 1 and left valve barrel 12 are built with spheroid 2, spheroid 2 is provided with seal ring 3 respectively and between right valve barrel 1 and left valve barrel 12, as shown in Figure 3, the top of spheroid 2 has a groove a, is also provided with the internal valve core body for the formation of ball valve internal valve between right valve barrel 1 and left valve barrel 12, internal valve core body lower end is inserted in groove a, and internal valve core body upper end is fixedly connected with handle 9.
As shown in Figure 2, the top of internal valve core body be threaded 11 valve rod 4, the bottom of internal valve core body is respectively discoid second spool 13, and block 5 is actively set in valve rod 4, and valve rod 4 is connected to the upper lateral part of the second spool 13.
As shown in Figure 1, the second spool 13 inserts in spheroid 2, in the gap of block 5 between the outer right valve barrel 1 of spheroid 2 and left valve barrel 12 by the groove a on spheroid 2.Groove a is opened and closed by realization under the drive of handle 9 by the second spool 13, and controls the keying of spheroid 2.
As shown in Figure 2, block 5 for cross section be trapezoidal structure, block 5 width is identical with stem diameter d2, and trapezoidal length direction is the length direction of block 5 and vertical with the disc face of the second spool 13.Block 5 in the middle part of valve rod 4, is used for determining whether the second valve body 13 is opened completely.
As shown in Figure 1, valve rod 4 is contained in the hole formed between right valve barrel 1 and left valve barrel 12, filler 6 is provided with and by Gland nut 7 press seal in hole, the screw thread 11 of valve rod 4 is enclosed within the Stem Mut 10 outside Gland nut 7, screw thread 11 coordinates with Stem Mut 10, and valve rod 4 top is fixedly connected with handle 9.Valve rod 4 and Stem Mut 10 realize the rotary opening and closing of the second spool 13 under the effect of handle 9, have opened and closed the rotary opening and closing controlling ball for ball valve 6 at the second spool simultaneously.When block 5 and filler 6 are collided, handwheel 9 can not continue to open, and just can determine that the second spool 13 is opened completely, play the flashboard function of the second spool 13.
Valve rod 4, block 5 and the second spool 13 are one-body molded.Second spool 13 be directly process with ball-valve valve rod 4 together with, and block 5 on valve rod 4 and threaded stem 10 together form an entirety.
Second spool 13 disk diameter is identical with the diameter d size of spheroid 2 inner chamber.
Ball valve top adds the space of placement second spool 13, and screw 8, for this region fastening, is avoided leaking.
Working principle of the present invention and working procedure as follows:
Consider ball valve failure of adjustment in use, cause and cannot normally open and close, cause fluid to leak; And the solid particle contained in water coal slurry are to the impact of ball valve body, cause wearing and tearing, ball valve is caused to lose efficacy.
The present invention is intended to the characteristic of characteristic by Bound moisture coal slurry and acceleration switching valve, use second spool 13 with flashboard function, what can realize ball valve changes up pass soon, reduce the wearing and tearing of ball valve body, leak the harm that environment is caused, extend the working life of ball valve, ensure that the cost that water-coal-slurry pipeline is carried.
When handle with sleeve 9, the screw thread 11 on the valve rod 4 of ball valve will move together with Stem Mut 10, drives internal valve core body rotate and carried out up and down axial motion by screw body, realizes the rotation of the second spool 13 in spheroid 2 and opens and closes.Because the second spool 13 is arranged in the groove a of spheroid 2, and then drive the rotation of spheroid 2.When the adjustment of ball valve is normal, rotates handwheel, allow the second spool 13 slowly rise, terminate until the second spool 13 opens and closes, wherein can control flow in pipeline and slowly increase, water coal slurry flow in pipeline can be avoided like this to increase instantaneously, destroy pipeline.Second spool 13 is rotated further handwheel after opening and closing and terminating, and the valve rod that handwheel connects drives the keying of ball valve body 2, plays the regulating action of ball valve.
Ball valve once in use failure of adjustment cannot close, can the flashboard function of fast onset second spool 13.Second spool 13 will be dropped to bottommost by handle with sleeve 9, and make the second spool 13 not be embedded in the groove a of spheroid 2, the second spool 13 can rotate separately, realizes the opening and closing of valve.
As can be seen here, the technology of the present invention Be very effective is given prominence to, and what realize ball valve changes up pass soon, and the ball valve with dual keying function reduces the harm of leaking and causing environment, extending the working life of ball valve, by reducing the solid contained in fluid in water-coal-slurry pipeline conveying, wearing and tearing being caused to ball for ball valve.
