[0002] The valve turbine head is a commonly used fluid dynamics controller, widely used in petroleum, chemical, electric power, metallurgy, papermaking, pharmaceutical and other fields. Its main function is to change the flow rate, flow rate and pressure distribution of the fluid to meet the needs of different working conditions. It has the advantages of good adjustability, stable flow rate, uniform pressure distribution and easy operation. Because it can efficiently and reliably control fluid power, it has broad application prospects in industrial production.

[0003] The existing valve turbine head is not convenient for real-time detection of the pressure of the fluid in the pipeline, and thus it is not convenient to adjust the valve in time according to the pressure of the fluid in the pipeline. If the pressure in the valve is too high and the staff fails to discover and deal with it in time, safety hazards are likely to occur, reducing the practicality of the valve turbine head.

DETAILED DESCRIPTION

[0021] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0022] like Figure 1 As shown, the utility model provides a valve turbine head with an alarm function, comprising a connecting pipe 1 and a turbine head body 2 installed on the connecting pipe 1 .

[0023] like Figure 2 As shown, the present embodiment also includes an alarm mechanism 3 disposed on the connecting pipe 1, the alarm mechanism 3 includes a groove 31 vertically opened at the inner bottom of the connecting pipe 1, a rubber pad 32 pasted to the inner bottom of the groove 31, and an arc-shaped pressing plate 34 movably installed in the groove 31 and located above the rubber pad 32;

[0024] The arc-shaped pressing plate 34 can move up and down along the inner side of the groove 31 to apply pressure to the pressure sensor 33, thereby indirectly calculating the pressure in the connecting pipe 1, the pressure sensor 33 installed on the rubber pad 32 and in contact with the arc-shaped pressing plate 34, and the connecting rod 35 vertically installed at the middle of the bottom end surface of the arc-shaped pressing plate 34 and movably passing through the rubber pad 32 and the bottom end surface of the connecting pipe 1;

[0025] An alarm component is provided under the arc-shaped pressure plate 34, and an alarm is sounded to remind the staff when the pressure detected in the connecting pipe 1 is too high;

[0026] The connecting rod 35 is movably extended into a fixing frame 38 installed at the bottom of the connecting pipe 1. A first sleeve 36 is fixedly sleeved on the connecting rod 35 and is fitted to the bottom of the connecting pipe 1. A spring 37 is installed at the bottom of the first sleeve 36. The spring 37 is movably connected to the bottom of the outer side of the connecting rod 35. An adjusting mechanism 39 is arranged below the spring 37 for adjusting the initial state of the spring 37 to adjust different alarm pressures in the connecting pipe 1.

[0027] In this embodiment, the alarm assembly includes a switch 310 fixedly embedded on the rubber pad 32 and located below the arc-shaped pressure plate 34, and an alarm 311 electrically connected to the switch 310 through a connecting cable. The alarm 311 is installed on the connecting pipe 1, and the alarm 311 is located outside the fixing frame 38, so as to remind the staff that a field occurs at the valve turbine head through the alarm 311;

[0028] The top surface of the switch 310 is lower than the top surface of the pressure sensor 33, so that the pressure in the connecting pipe 1 is detected by the pressure sensor 33 under normal circumstances, and the alarm 311 is activated by squeezing the switch 310 when the pressure in the connecting pipe 1 is too high, thereby improving the flexibility during use;

[0029] In this embodiment, the alarm 311 is an audible and visual alarm, which is convenient for the staff to more intuitively observe the abnormal pressure in the valve turbine head;

[0030] The electrical device in this embodiment is connected to the external control device, which is the prior art;

[0031] When in use, the fluid in the connecting pipe 1 applies pressure to the arc pressure plate 34 when flowing through, and the pressure sensor 33 detects the pressure on the arc pressure plate 34 and transmits the detected information to the external control device. The pressure in the connecting pipe 1 is indirectly calculated by the pressure detected by the pressure sensor 33. When the pressure in the connecting pipe 1 is too large, the arc pressure plate 34 and the connecting rod 35 move downward to overcome the elastic force of the rubber pad 32 and the spring 37 respectively. At this time, the arc pressure plate 34 squeezes the switch 310 downward to turn on the alarm 311, and the alarm 311 generates an alarm sound. The staff can promptly operate and adjust the turbine head body 1 or adjust the inflow of fluid through the alarm sound to reduce safety hazards.

[0032] like Figure 3 As shown, in this embodiment, the adjustment mechanism 39 includes a second ring 391 connected to the bottom of the spring 37, and the second ring 391 is movably installed in the guide cylinder 392. The second ring 391 can move vertically up and down along the inner side of the guide cylinder 392, and the inner ring of the second ring 391 is fixed with a spring rod 393 that movably extends into the spring 37;

[0033] The guide cylinder 392 is locked and fixed on the bottom end surface of the connecting pipe 1, and the inner ring of the guide cylinder 392 is slidably connected with the first sleeve 36. The first sleeve 36 can move up and down along the inner side of the guide cylinder 392, which improves the stability of the first sleeve 36 during the movement. The spring rod 393 passes through the inner side of the guide cylinder 392 and fits with the trapezoidal block 394.

[0034] The trapezoidal block 394 is slidably connected to the inner bottom of the fixing frame 38, and a screw 395 is movably passed through the left and right end surfaces of the trapezoidal block 394. The screw 395 is rotatably mounted on the fixing frame 38. The screw 395 can be vertically rotated in the fixing frame 38 to adjust the position of the trapezoidal block 394;

[0035] The bottom of the spring rod 393 is an arc-shaped structure, which facilitates the trapezoidal block 394 to push the spring rod 393 to move vertically up and down to adjust the initial elastic coefficient of the spring 37;

[0036] In this embodiment, the screw rod 395 is a T-shaped structure, and its large head portion is located outside the fixing frame 38, which facilitates the rotation of the screw rod 395;

[0037] In this embodiment, a threaded hole is provided on the trapezoidal block 394, which passes through the left and right end surfaces, and the inner circle of the threaded hole matches the outer surface of the screw 395, so that the screw 395 matches the threaded hole to drive the trapezoidal block 394 to move horizontally in the fixing frame 38;

[0038] Among them, there are two groups of alarm components, and the two groups of alarm components are respectively located at the left and right ends of the bottom of the arc-shaped pressure plate 34, which is more conducive to the staff to observe the abnormal pressure in the valve turbine head;

[0039] During use, when it is necessary to adjust the value of the fluid pressure alarm in the valve turbine head 2, the screw 395 can be rotated to cooperate with the threaded hole on the trapezoidal block 394 to drive the trapezoidal block 394 to move horizontally in the fixing frame 38. The trapezoidal block 394 moves to the left to apply pressure to the spring rod 393, and the spring rod 393 drives the second ring 391 to move upward to apply pressure to the spring 37. The spring 37 is compressed, and the elastic coefficient of the spring 37 becomes smaller. A greater pressure of the fluid in the connecting pipe 1 is required to overcome the elastic force of the spring 37. Therefore, the alarm 311 will sound an alarm only when the fluid pressure in the connecting pipe 1 reaches a higher value. After the trapezoidal block 394 moves to the left, the second ring 391 moves downward under the elastic force of the spring 37. The spring 37 is stretched and the elastic coefficient becomes larger. At this time, when the fluid pressure in the connecting pipe 1 is small, the alarm 311 will sound an alarm, which is convenient for adjustment according to actual usage and improves the flexibility of the valve turbine head.
