The present invention changes the connection mode of the switching passage between the connecting pipe and the discharging pipe through the conical valve plug, reduces the pressure of the inlet pipe when switching the passage, and automatically converts the passage through the motor, which is convenient for operation.
Description
The technical field is as follows:
the invention relates to a device for automatically changing a pipeline passage, in particular to a wide-mouth type novel two-way valve with mechanical seal.
Background art:
at present, the existing two-way valve change valve plug in China is mostly U-shaped, the sealing performance is poor, the appearance is bloated, and the inlet is completely closed when the passage is changed, so that the material blockage in a conveying pipeline can occur, and the use of related equipment is adversely affected, aiming at the situation.
The invention content is as follows:
the technical problem to be solved by the invention is as follows: overcome prior art not enough, provide a simple structure, reduce the novel double-way valve of wide-mouthed formula with mechanical seal of inlet line pressure when switching the route.
The technical scheme of the invention is as follows: a wide-mouth novel two-way valve with mechanical seal comprises a feeding pipe and a discharging pipe, wherein the discharging pipe comprises a first discharging pipe and a second discharging pipe, one end of the first discharging pipe and one end of the second discharging pipe are connected in a crossed mode through an inclined notch to form an inclined circular connecting port, a triangular fixing support is arranged at the connecting position of the first discharging pipe and the second discharging pipe, the circular connecting port is connected with the feeding pipe through a flange, a conical valve plug is arranged in the circular connecting port, one end of the conical valve plug is in a wide-mouth type, is arranged in the circular connecting port and is matched with the circular connecting port for use, an oval hole which is matched with the inclined notch for use to realize the communication between the feeding pipe and the discharging pipe is arranged on the conical connecting port, the other end of the conical valve plug penetrates through the first discharging pipe and the second discharging pipe and is connected with a screw rod which, the screw rod is connected with a motor arranged on the triangular fixing support, and a limiting device used for communicating the oval hole with the inclined notch is arranged on the screw rod.
The flange is the slope setting, and flange, conical valve plug and screw rod setting on same axis, the ellipse circular hole is one, and the material is rubber.
Discharging pipe and inlet pipe all are connected with inlet pipe and export pipeline through flange, triangle-shaped fixed bolster with first discharging pipe and second discharging pipe are the welding, stop device is angle sensor.
The invention has the beneficial effects that:
1. the invention changes the connection mode of the switching passage of the material connecting pipe and the material discharging pipe through the conical valve plug, reduces the pressure of the inlet pipeline when the passage is switched, and automatically switches the passage through the motor, thereby being convenient for operation.
2. One end of the conical valve plug is provided with a wide opening, the wide opening type valve plug is used for feeding, the higher the pressure of the pipeline is, the more the rubber at the wide opening of the conical valve plug can be tightly attached to the inner wall of the pipeline, and the better the sealing property is.
3. The conical valve plug is provided with the oval hole, and when the conical valve plug rotates to any position, the situation that the inlet pipe is completely blocked or two outlet pipes are simultaneously blocked is avoided, so that the pressure of an inlet pipeline is not increased, and the adverse effect on related equipment is avoided.
4. The triangular fixing support is arranged, so that the connection strength of the first discharging pipe and the second discharging pipe is ensured, the motor and the screw rod are fixed, and the conical valve plug is prevented from shifting due to the pressure of the feeding pipe when the screw rod drives the conical valve plug to rotate.
5. The invention is provided with the angle sensor, and the detection of the position of the oval hole on the conical valve plug is realized by detecting the rotation angle of the screw rod, so that the path changing adjustment is convenient.
Description of the drawings:
fig. 1 is a first structural schematic diagram of a wide-mouth type novel two-way valve with a mechanical seal.
Fig. 2 is a structural schematic diagram of a wide-mouth type novel two-way valve with a mechanical seal.
The specific implementation mode is as follows:
example (b): referring to fig. 1 and 2, there are 1-feed pipe, 2-first discharge pipe, 3-second discharge pipe, 4-inclined cut, 5-triangular fixed support, 6-flange, 7-conical valve plug, 8-elliptical hole, 9-screw, 10-motor, 11-connecting flange, 12-inlet pipe, 13-outlet pipe.
A wide-mouth novel two-way valve with mechanical seal comprises a feeding pipe 1 and a discharging pipe, wherein the discharging pipe comprises a first discharging pipe 2 and a second discharging pipe 3, one end of the first discharging pipe 2 and one end of the second discharging pipe 3 are in cross connection through an inclined notch 4 to form an inclined circular connecting port, a triangular fixing support 5 is arranged at the connecting position of the first discharging pipe 2 and the second discharging pipe 3, the circular connecting port is connected with the feeding pipe 1 through a flange 6, a conical valve plug 7 is arranged in the circular connecting port, one end of the conical valve plug 7 is in a wide-mouth shape and is arranged in the circular connecting port and is matched with the circular connecting port, an oval hole 8 which is matched with the inclined notch 4 to realize the communication between the feeding pipe 1 and the discharging pipe is arranged on the conical valve plug 7, the other end of the conical valve plug 7 penetrates through the first discharging pipe 2 and the second discharging pipe 3 and is connected with, the screw rod 9 is connected with a motor 10 arranged on the triangular fixing support 5, and a limiting device used for communicating the elliptical hole 8 with the inclined notch 4 is arranged on the screw rod 9.
The flange 6 is the slope setting, and flange 6, conical valve plug 7 and screw rod 9 set up on same axis, and oval hole 8 is one, and the material is rubber.
Discharging pipe 1 and inlet pipe all are connected with inlet pipe 12 and export pipeline 13 through flange 11, and triangle-shaped fixed bolster 5 is the welding with first discharging pipe 2 and second discharging pipe 3, and stop device is angle sensor.
During the use, during inlet pipe 1 feeding, drive screw rod 9 and conical valve plug 7 through motor 10 and rotate, because conical valve plug 7 rotates with screw rod 9 is synchronous, detect the detection that realizes conical valve plug 7 rotation angle to screw rod 9 rotation angle through angle sensor, realize that oval hole 8 corresponds with the accuracy of slope notch 4 on first discharging pipe 2 and the second discharging pipe 3 on conical valve plug 7, follow conical valve plug 7's rotation through oval hole 8, realize oval hole 8 to the correspondence of different slope notches 4, accomplish the switching of route and adjust.
