The present application provides a diverter valve structure for switching the direction of delivery of a fluid such as a powder, gas or liquid. Referring to fig. 1 to 5, the directional valve structure of the present application mainly includes a main valve body 10, a ball plug 20, a plurality of adapter seats 30 and a plurality of abutment rings 40.

The main valve body 10 has a chamber 11 and a plurality of mounting openings 12. Each mounting port 12 is respectively communicated with the accommodating cavity 11. In the present embodiment, the number of the mounting openings 12 is three, but the present application is not limited thereto, and the number of the mounting openings 12 may be four or more. It should be noted that the angles and distances between the mounting ports 12 may be determined according to the practical requirements, and the drawings of the present application only disclose the aspects thereof, and are not intended to limit the angles and distances between the mounting ports 12.

The ball plunger 20 is a metal ball. In the present embodiment, the ball plunger 20 is made of stainless steel, but the present application is not limited thereto, and the ball plunger 20 may be made of other hard metals. The ball plug 20 is rotatably disposed in the cavity 11 and connected to a driving rod a penetrating out of the main valve body 10, so that the ball plug 20 can be controlled to rotate from the outside of the main valve body 10. The ball plunger 20 has at least one passage 21. In the present embodiment, the number of the channels 21 is one, but the present application is not limited thereto, and for example, when the number of the mounting ports 12 is more than four, the number of the channels 21 may be more than one, so as to observe the actual direction-finding requirement. The passage 21 selectively communicates with two of the mounting ports 12. Thereby, the fluid such as powder, gas or liquid can only flow along the two corresponding mounting openings 12 at the two ends of the channel 21, but not flow to the other mounting opening 12; when the direction of the flowing pipeline needs to be changed, the driving rod A is only required to rotate the ball plug 20, so that one end of the channel 21 is correspondingly communicated with the other mounting port 12.

Each adapter 30 is disposed at each mounting port 12, so as to be connected by a plurality of pipelines (not shown). The adaptor 30 in the embodiment is locked on the mounting opening 12 by a plurality of bolts, so as to facilitate disassembly, replacement and maintenance, but the application is not limited thereto. Each adapter 30 extends toward the cavity 11 in the main valve body 10 with a connecting tube 31, i.e., each connecting tube 31 is respectively received in each mounting opening 12, as shown in fig. 2.

Referring to fig. 2 to 7, each of the abutting rings 40 is sleeved on the outer edge of each of the connecting pipes 31. Each abutment ring 40 comprises a ring body 41 and a babbitt washer 42. In the present embodiment, the ring 41 is made of stainless steel, but the present application is not limited thereto, and for example, the ring 41 may be made of other hard metals. Each ring body 41 is provided with an annular dovetail slot 411, and each Babbitt metal gasket 42 is respectively embedded in each annular dovetail slot 411 and jointly abuts against the ball plug 20. The babbitt metal gasket 42 is composed of babbitt metal, which has the main alloy components of tin, lead, antimony and copper, wherein tin and lead are soft phase matrix, antimony and copper are hard particles, the soft phase matrix can reduce friction, and the hard particles can be used as support for bearing, so that the babbitt metal has good support and low friction characteristics.

In the present embodiment, the Babbitt metal gasket 42 is one of a tin-based Babbitt metal and a lead-based Babbitt metal, which are different in terms of the amount of tin and the amount of lead, wherein the strength, hardness, wear resistance, and corrosion resistance of the tin-based Babbitt metal are superior to those of the lead-based Babbitt metal. Therefore, through the good embedding property, compliance and seizure resistance of the Babbitt metal, after running in, the soft phase matrix is concave, and the hard particles are convex, so that a tiny gap is formed between sliding surfaces to be beneficial to reducing friction, and the convex hard particles play a good supporting and bearing role, so that the Babbitt metal gasket 42 can directly abut against the ball plug 20, and the surface hardening treatment on the ball plug 20 and the abutting ring 40 is omitted, thereby reducing environmental pollution, production cost and manufacturing procedures.

Referring to fig. 7, each annular dovetail slot 411 has a trapezoidal cross section, and each babbitt metal gasket 42 extends with a fitting block 421, and the shape of the fitting block 421 corresponds to the shape of the annular dovetail slot 411 so that the babbitt metal gasket 42 is fitted on the annular dovetail slot 411. Specifically, a first inner diameter t1 is formed at the opening of each annular dovetail slot 411, and a second inner diameter t2 is formed at the bottom of each annular dovetail slot 411. The first inner diameter t1 is smaller than the second inner diameter t2 such that the inner wall of the annular dovetail slot 411 becomes wider from the opening toward the bottom, thereby being able to act as a stop to prevent the babbitt washer 42 from escaping the annular dovetail slot 411. As shown in fig. 3, the center of the ring body 41 of each abutment ring 40 defines a central axis 43, and the annular dovetail slots 411 are inclined toward the corresponding central axis 43, so that the babbitt washer 42 can effectively abut against the ball plug 20. Specifically, each babbitt metal washer 42 has a bearing surface 422 that abuts ball plunger 20. The support surface 422 is located on a side of the babbitt metal washer 42 remote from the corresponding annular dovetail slot 411, and the support surface 422 is at an angle θ of about 45 ° to the central axis 43. Thus, the babbitt metal gasket 42 is not only effective to abut the ball plunger 20 via the support surface 422, but is also effective to support the carrier ball plunger 20 via the support surface.

Referring back to fig. 2 to 5, the diverter valve structure of the present application further includes a plurality of bundles 50 and a plurality of elastic fixing rings 60. The bundles 50 are respectively sleeved on the outer edges of the connecting pipes 31, and bind and clamp the corresponding ring bodies 41. Specifically, each of the barrels 50 has a buckle 51, and each of the rings 41 has a catch groove 412. Each clip 51 is respectively fastened to each clip groove 412, so that each bundle 50 can clamp each corresponding ring 41 without causing the ring 41 to fall off from the connecting tube 31. Referring to fig. 3 and 5, after the buckle 51 is fastened in the fastening slot 412, the ring 41 is prevented from being separated upward in the drawing. The elastic fixing rings 60 are respectively clamped between the connecting pipes 31 and the binding barrels 50, thereby vertically limiting the binding barrels 50. Specifically, semicircular grooves (not shown) are formed on the outer edge of the connecting tube 31 and the inner wall of the bundle tube 50 for the elastic fixing ring 60 to be engaged, so as to prevent the bundle tube 50 from moving up and down in fig. 3 and 5, and further effectively ensure the fixation of the ring body 41.

Referring back to fig. 3 to 5, in order to further ensure the tightness between the connection pipe 31 and the abutment rings 40, each abutment ring 40 further includes a rubber ring 44. The inner wall of each ring body 41 is concavely provided with a groove 413, and each rubber ring 44 is respectively accommodated in each groove 413 and is abutted against each corresponding connecting pipe 31. This ensures that fluid such as powder, gas or liquid leaks from between the outer edge of the connection pipe 31 and the inner edge of the contact ring 40, and effectively ensures the sealing performance of the directional valve. In order to ensure that the babbitt washer 42 of the abutment ring 40 can effectively abut against the ball plunger 20, the directional valve structure of the present application further includes a plurality of disc springs 80. The outer wall of each connecting tube 31 extends outward to have steps (not shown), and each disc spring 80 is respectively disposed on each step and elastically abuts against the corresponding ring body 41, so that each abutment ring 40 can be abutted against the ball plunger 20 by the pushing of each disc spring 80. It should be noted that, in each adaptor 30 in the present embodiment, the disc spring 80 and the abutment ring 40 are bound and limited on the connecting tube 31 by the binding tube 50, but the present application is not limited thereto.

Referring to fig. 8, another embodiment of the present application is mainly different in that the aforementioned components and features of the collar 50, the buckle 51, and the slot 412 are not included, but the outer wall of each ring 41 extends to a side away from the annular dovetail slot 411 to form a collar portion 414, and the outer edge of each connecting tube 31 is provided with a collar wall 311. The binding ring portions 414 are respectively sleeved on the outer edges of the ring walls 311 to play a role in binding and clamping. In addition, each elastic fixing ring 60 in the present embodiment is respectively clamped between each annular wall 311 and each collar portion 414, so as to limit the ring body 41. Specifically, grooves (not shown) are formed on the outer edge of the annular wall 311 and the inner wall of the collar portion 414, respectively, for the elastic fixing ring 60 to engage, thereby preventing the ring body 41 from moving in the up-down direction in fig. 8, and effectively securing the abutment ring 40.

Further illustratively, in the embodiment of fig. 8, the directional valve structure further includes a plurality of wave springs 70. A receiving space 312 is formed between each annular wall 311 and the corresponding connecting tube 31, and each wave spring 70 is respectively located in each receiving space 312 and elastically abuts against each corresponding annular body 41. Accordingly, the contact ring 40 can be buffered by the wave spring 70 to have a certain degree of inward contraction margin, and structural interference damage is not directly caused by an excessive load bearing force of the contact ring 40.

In the diverter valve structure of the present utility model, the ball plug 20 is abutted by the babbitt metal gasket 42 fitted in the annular dovetail slot 411, so that the surface hardening treatment of the ball plug 20 and the abutment ring 40 can be omitted, thereby effectively reducing environmental pollution, reducing production cost and shortening manufacturing processes.

In view of the foregoing, the present application has industrial applicability, novelty and advancement, fully meets the requirements of the patent application, and is filed by the patent law. Of course, various other embodiments of the present application are possible, and those skilled in the art will readily devise numerous modifications and variations which, although they may come within the scope of the present application, embody the teachings of the present application and are thus within its true scope.
