The technical means by which this creation is used to achieve the above objectives are described in detail below with the following implementation diagrams, which are further understood and agreed upon.

Please refer to FIG. 1 and FIG. 4 simultaneously. The present invention is a valve type locomotive throttle valve 200 including an air inlet seat 210, an air outlet seat 220, and an opening and closing control structure 100.

The air inlet 210 has an air inlet 211 and a first recess 212. The air inlet 211 is disposed adjacent to the lower end, and the first recess 212 is disposed adjacent to the upper end.

The air outlet 220 is disposed opposite to the air inlet 210 and defines an internal space. The air outlet 220 has an air outlet 221 and a second recess 222. The air outlet 221 is disposed adjacent to the lower end and is corresponding to the air inlet 211 and communicates with each other. The two recesses 22 are disposed adjacent to the upper end and are disposed corresponding to the first recesses 212, and the first recesses 212 and the second recesses 222 define an embedded space.

A sealing frame 230 is disposed between the circumference of the air inlet 1 and the circumference of the air outlet 2, and the sealing frame 230 is correspondingly disposed with a recess 231 corresponding to the first recess 212 and the second recess 222. Thereby, the fluid leakage in the internal space is prevented, and the effect of further preventing leakage is achieved.

The opening and closing control structure 100 of the present invention includes a valve assembly 1, a control assembly 2, and a spring member 3.

The valve assembly 1 has a valve body 11 and a row of teeth 12, and the teeth 12 are provided The valve body 11 is substantially square, as shown in FIG. The upper end of the valve body 1 protrudes upwardly with a tenon 13 corresponding to the space defined by the first recess 212 and the second recess 222.

The control assembly 2 is disposed on a side of the valve body 11 having the teeth 12, and the control assembly 2 includes at least a pivot 21 and a rotating block 22, the pivot 21 passing through the rotating block 22 to drive the rotating block 22 to pivot, the rotating block 22 It is movably disposed between the air inlet 210 and the air outlet 220. The side of the rotating block 22 has a tooth portion 23, as shown in FIG. 1, the rotating block 22 can be a quarter circle, and the tooth portion 23 is disposed at an arc of the quarter circle (the rotating block 22), the tooth portion 23 is engaged with the tooth 12, and the axis of the pivot 21 extends and the axis of the air inlet 211 or the air outlet 221 extends. The pivoting angle of the pivot 21 driving the rotating block 22 may be greater than or equal to 90 degrees, but not limited thereto; the pivoting of the pivot 21 drives the rotating block 22 to rotate and further penetrates the teeth. The portion 23 is engaged with the teeth 12 to drive the teeth 12 and the valve body 11 to move up and down.

One end of the spring member 3 is fastened to the tenon 13 of the valve body 1, and the other end is embedded in the first recess 212 and the second recess 222 (the defined recessed space).

In addition, the pivot 21 is sleeved with a resilient member 24 (such as the spring shown in FIG. 1) to control the pivot 21 to be reset.

Therefore, as shown in FIGS. 1 and 3, when the pivot 21 is rotated in the clockwise direction, the pivoting of the pivot 21 drives the rotary block 22 to rotate, and further penetrates the meshing portion 23 with the teeth 12, The driving gear 12 and the valve body 11 are moved downward, so that the valve body 11 closes the communication between the air inlet 211 and the air outlet 221 to be in a completely closed state (as shown in FIG. 3), and the spring member 3 is utilized. The arrangement of the valve body 11 can make the closing/closing of the valve body 11 more reliable, and the degree of occlusion between the tooth portion 23 and the row of teeth 12 is more stable without loosening, and the elastic member 24 at this time is in a tight state, and The pivoting angle of the pivot 21 may preferably be 90 degrees or may be greater than 90 degrees; after that, the pivoting force of the elastic member 24 is used to bias and pivot the pivot 21 in the counterclockwise direction to drive the rotation. The block 22 rotates, and further penetrates the meshing portion 23 and the teeth 12 to move the tooth 12 and the valve body 11 upward, so that the valve body 11 opens into the communication between the air hole 211 and the air outlet 221, at this time The resilient member 24 assumes a normal state of release to be in a fully open state (as shown in Figure 4).

Therefore, with the above structure, the tooth portion 23 of the rotary block 22 is engaged with the teeth 12 of the valve assembly 1 to further control the valve body 11 to close or open the communication between the air inlet 211 and the air outlet 221, not only the communication between the air inlet 211 and the air outlet 221 is controlled. The structure is simplified, and the movement position (positioning) of the valve body 11 can be precisely controlled by the engagement between the teeth and the teeth, and the arrangement of the spring member 3 is utilized at the same time to make the degree of engagement between the tooth portion 23 and the teeth 12 more stable. Therefore, it is not loose, so that the closing/closing of the valve body 11 is more sure, and the situation that the fluid is leaked due to the abnormality of the closing of the fluid (such as gas) is prevented.

The above description of the embodiments is intended to be illustrative of the present invention and is not intended to limit the present invention, so any change in the value or substitution of equivalent elements should still fall within the scope of the present invention.

From the above detailed description, it will be apparent to those skilled in the art that the present invention can achieve the aforementioned objectives, and has been in compliance with the provisions of the Patent Law, and has filed a patent application.
