Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below. The structure, ratio, size and the like shown in the drawings of the present specification are only used for matching with the content disclosed in the specification, so as to be known and read by people familiar with the technology, and are not used for limiting the limit conditions which can be implemented by the present invention, so that the present invention does not have the substantial significance in the technology, and any structure modification, ratio relationship change or size adjustment should still fall within the scope which can be covered by the technical content disclosed by the present invention without affecting the efficacy which can be produced by the present invention and the achievable purpose. In addition, the terms "upper", "lower", "left", "right" and "middle" used in the present specification are for clarity of description, and are not intended to limit the scope of the present invention, and the relative relationship between the terms and the terms is not to be construed as a scope of the present invention.
Referring to fig. 1 and 2, an explosion-proof pneumatic ball valve includes a valve body 1, a plurality of medium channels 11 are provided in the valve body 1, a support 2 is connected to a lower portion of the valve body 1, a pneumatic actuator 3 is installed on the support 2, a ball valve core 4 is provided in the valve body 1, and an actuating rod 31 of the pneumatic actuator 3 is connected to the ball valve core 4. The valve body 1, the bracket 2, the actuating rod 31 and the pneumatic actuator 3 are all in the existing structure, the working principle of the pneumatic ball valve is the same as that of the existing pneumatic ball valve, and the details are not repeated here.
The ball valve core 4 is provided with a medium discharge hole 41. The actuating rod 31 is provided with a medium discharge passage 32. The inlet and outlet ends of the medium discharge passage 32 are arranged in the horizontal direction, and the intermediate portion of the medium discharge passage 32 is arranged in the vertical direction. The lower end of the medium discharge passage 32 is connected to the medium discharge hole 41. The medium discharge hole 41 and the end of the medium discharge passage 32 have a screw joint, and the connection pipe 7 is connected between the medium discharge hole 41 and the medium discharge passage 32 by a screw. Since the ball valve core 4 and the actuating rod 31 are integrally rotated and connected by the connecting pipe 7, the connecting pipe 7 is prevented from falling off due to high-pressure impact by having a threaded connection structure. The medium discharge passage 32 has a certain volume, and can slightly reduce the pressure in the ball valve element 4 even in a high-pressure state. The number and position of the medium discharge holes 41 are not limited to those identified in fig. 2, and more than two medium discharge holes 41 may be employed. Similarly, the size of the medium discharge passage 32 may be set to match the medium discharge hole 41 according to actual needs.
The support is also provided with a medium discharging box 5, a medium inlet 51 of the medium discharging box 5 is provided with a one-way valve 6, and the one-way valve 6 is a one-way valve matched with the existing one-way valve. The check valve 6 is connected to the upper end of the discharge medium passage 32. When the internal pressure of the ball valve element 4 is excessive, the medium enters the medium discharge tank 5 through the medium discharge hole 41 along the medium discharge passage 32 via the check valve 6 and is discharged from the medium discharge tank 5. The one-way valve 6 plays a role of one-way opening, under a normal condition, the pneumatic actuator drives the execution rod 31 to rotate, the execution rod 31 drives the ball valve core 4 to rotate, two medium channels in the valve body 1 are communicated after the ball valve core 4 rotates for a certain angle, and the pneumatic ball valve is in a normal working state. Under normal pressure, the medium will fill the medium discharge passage 32 through the medium discharge hole 41, but due to the function of the check valve 6, the check valve 6 cannot be opened under the condition of insufficient medium pressure, so the check valve 6 is closed at this time, and internal pressure relief is not realized. Under normal conditions, the one-way valve 6 blocks the medium discharge channel 32, and no medium leaks out. When the pressure in the spherical valve body 1 is too high, the high-pressure medium is also arranged in the medium discharge channel 32, the pressure of the medium can open the check valve 6, the medium enters the medium discharge box 5 through the check valve 6, and the pressure in the spherical valve body 1 is reduced to keep the normal pressure in the spherical valve body 1.
The medium outlet 52 is provided in the medium outlet 5, the medium inlet 51 is provided with a screw joint, and the flexible hose 8 is connected between the medium inlet 51 and the medium outlet channel 32 through screw threads. The medium is discharged through the medium outlet 52 in the state of over-high pressure, the medium outlet 52 is connected with the medium source part through a pipeline, the medium flows back to the medium source part, the medium is effectively recycled, and the medium can be prevented from overflowing and scattering. Since the actuating rod 31 is rotated relative to the discharge medium tank 5, the flexible hose 8 is used and a suitable length (not shown) is adjusted, so that the flexible hose 8 is not dropped during the rotation, and the connection strength is further improved by the screw joint.
A flow sensor 53 is provided at the medium outlet 52. The flow sensor is used for detecting the flow of the medium port 52, and if the flow sensor detects that the flow is always too large, the pneumatic actuator can be closed to avoid the damage of the spherical valve body 1 caused by the fact that the inside cannot be decompressed in time.
The ball valve core 4 is connected with the valve body 1 in a dynamic sealing mode through a sealing ring, the medium discharge hole 41 is arranged along the radial direction of the ball valve core, and the upper end of the medium discharge hole 41 is located above the sealing ring. The discharge medium box 5 is detachably mounted above the side of the bracket.
Be different from prior art, the utility model discloses explosion-proof pneumatic ball valve can prevent that valve body internal pressure is too big and cause the spheroid case to damage, in time with inside high-pressure discharge, ensures that the medium moves the ball valve and can the safety in utilization.
The present invention and its embodiments have been described above schematically, and the description is not limited thereto, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art should understand that without departing from the spirit of the present invention, the person skilled in the art should not inventively design the similar structural modes and embodiments to the technical solution, and all shall fall within the protection scope of the present invention.
