The present invention relates to a gate valve, and more particularly to a gate valve having a locking function.

A valve body mechanism for selectively closing or opening a valve port in a housing, wherein the valve port has a valve seat surface, wherein the valve body mechanism includes at least one valve member, is disclosed in US Pat. No. 7,341,237. Parallel or vertical movement in the housing relative to the valve seat surface; a drive plate is disposed in the housing and coupled to the at least one valve member, the drive plate is translatable in the valve body, thereby causing at least one valve member Produce parallel movements.

However, although the valve body mechanism can drive the valve member to generate translational and vertical displacement through the driving plate to close the valve port, the valve body mechanism does not have any locking device or means for firmly locking the valve member in the closed position. In the above, the driving plate is easily subjected to external factors and forced to generate micro-motion or displacement, which will make the valve member unable to effectively adhere to the valve port. In severe cases, the valve port will leak fluid, resulting in unnecessary loss of the manufacturer.

In order to solve the above problems, the present invention discloses a gate valve having a locking function, which utilizes a non-linear driving trajectory for the rolling element of the swing arm to generate a circular motion along it, by sliding the sliding seat to close the valve member.

Wherein, the swing arm 40 is composed of two pieces, and the lock 43 can be clamped to the two pieces to be fixed. Thereby, the driver 20 can drive the swing arm 40 to perform a circular motion between the first locking position and the second locking position along the driving track 32 of the rolling member 42 for driving the sliding seat 30 to slide on the body 10 Between one end 11 and the second end 12. It is worth mentioning that when the swing arm 40 is in the first locking position or the second locking position, the swing arm 40 is offset from the moving path direction of the slider 30. When the swing arm 40 is in the first locking position and the second locking position, the rolling members 42 are located at the ends of the third driving segment 323. As shown in FIGS. 9A to 9D, the arrow B is the biasing direction of the swing arm 40.

The valve member 50 is disposed on the carriage 30 for parallel or vertical displacement relative to the valve port 13. The valve member 50 has two second guiding portions 51 connected to the first guiding portion 35 for closing the valve opening 13 when interlocked with each other. Preferably, the second guiding portion 51 and the first guiding portion 35 have a similar structure, which are respectively composed of two second plates 52 which are parallel and spaced apart by a distance, and each of the second plates 52 has two matching grooves. The fitting groove 53 has the same shape as the connecting groove 37 and is disposed at 180 degrees. The mating slot 53 also has a first end 531, a second end 532, and a skewed section 533 therebetween, as shown in Figures 8A-8C. Each of the two second plates 52 is disposed between each of the two first plates 36, and a linking plate 70 is further disposed between each of the second plates 52. The two sides of the valve member 50 respectively have a guiding roller 54 for rolling contact with the guiding piece 14.

When the rolling member 42 of the swing arm 40 is moved into the driving slot 31 and moved to the second driving portion 322, the guiding roller 54 enters the bent portion 151 of the positioning groove 15, and the valve member 50 can be guided by the first guide. The guiding portion 35 is in a linked relationship with the second guiding portion 51 and is vertically displaced with respect to the valve opening 13. Further, when the rolling member 42 of the swing arm 40 is moved into the driving chute 31 and moved to the third driving stage 323, the guiding roller 54 enters the end portion 152 of the positioning groove 15 so that the valve member 50 closely And the valve port 13 is stably closed, as shown in FIG.

As shown in FIGS. 8A to 8C, the movement path of the round rod 60 in the joint groove 37 and the fitting groove 53 will be described. As shown in FIG. 8A, the rounding rod 60 is disposed at the first end 371 of the connecting groove 37 and the second end 532 of the engaging groove 53 through the mating connecting groove 37 and the matching groove 53, and the position is an overlapping area. The round rod 60 is restrained from being engaged by the arcuate end portions of the connecting groove 37 and the engaging groove 53, so as to form a stationary shape and to avoid swaying.

As shown in FIG. 8B, when the carriage 30 is translated in the direction of the arrow A (as shown in FIG. 2), the connecting groove 37 and the engaging groove 53 are interlocked with the round rod 60 until the guiding roller 54 enters the positioning. The end portion 152 of the groove 15 allows the valve member 50 to move vertically toward the valve port 13.

As shown in FIG. 8C, when the rolling member 42 of the swing arm 40 is moved to the third driving stage 323 (as shown in FIG. 3), the round rod 60 can be positioned at the second end 372 of the connecting groove 37 and the matching groove. The first end 531 of the 53 is again formed into a stationary shape, so that the valve member 50 stably seals the valve opening 13.

As shown in Figures 9A-9D, the swing arm 40 is shown in various different positions relative to the drive chute 31. As shown in FIG. 9A, the swing arm 40 is located at the first locking position, and the rolling member 42 is located at the end of the third driving segment 323. At this time, the sliding bracket 30 is at the first end 11 of the body 10, as shown in FIG. 2 is shown.

As shown in FIG. 9B, the swing arm 40 is driven and moved along the drive trajectory 32 of the drive chute 31 to the end of the first drive section 321.

As shown in FIG. 9C, the rolling member 42 of the swing arm 40 moves from the first driving segment 321 to the second driving segment 322. At this time, the sliding bracket 30 approaches the second end 12 of the body 10 and causes the guiding roller. 54 enters the bent portion 151 of the positioning groove 15 to vertically displace the valve member 50 toward the valve port 13 to close the valve port 13, and when the guide roller 54 enters the end portion 152 of the positioning groove 15, the valve member can be made 50 closes the valve port 13 tightly and stably. As shown in Figure 5.

As shown in FIG. 9D, the swing arm 40 is in the second locking position, and the rolling member 42 is again located at the end of the third driving segment 323. When the swing arm 40 is in the first locking position or the second locking position, the pendulum is placed. The direction of the movement path of the arm 40 relative to the carriage 30 is offset, so that the slider 30 can be prevented from swaying, so that in the second locking position, the valve member 50 seals the valve port 13 more tightly, preventing the lateral force from acting on the sliding On the seat 30, it affects the sealing effect of the valve member 50 on the valve port 13.

The above embodiments are merely illustrative of the present invention and are not intended to limit the scope of the present invention. Any modification or change that is not in violation of the spirit of this creation is the scope of patent application for this creation.
