Description
Technical Field
The utility model relates to a relief pressure valve technical field, concretely relates to take positioner's electronic relief pressure valve device.
Background
In the process of a steam-water power generation system of a power plant, the steam-water system needs to be sampled so as to analyze the quality of steam-water, so as to avoid corrosion and damage to equipment caused by the quality of water; and because the steam-water power generation system is in a working high-pressure state, when steam-water is sampled, the steam at the sampling point needs to be cooled and depressurized, and then corresponding steam-water quality analysis is carried out. In the process of pressure reduction, sample water is generally introduced into a pressure reducing valve, and the pressure reduction is achieved by adjusting the pressure reducing valve. Because the pressure in the system and the pressure after depressurization are very different, the number of thread turns of the pressure reducing valve is more, the adjusting workload of operators is larger during adjustment, and the sample water flow is changed frequently due to the continuous change of the working condition of the system, so that the maintenance and adjustment are also frequently required by the personnel. In addition, in the operation process of the pressure reducing valve, the host cannot obtain the current position of the pressure reducing valve due to blockage, power failure or data loss of the pressure reducing valve, so that the automatic control system breaks down, and the operation of the whole system is influenced.

In order to achieve the above object, the utility model adopts the following technical scheme:
the utility model provides a take positioner's electronic relief pressure valve device, electronic relief pressure valve device is including electronic relief pressure valve, electronic relief pressure valve device is still including mounting panel, casing, step motor and encoder, wherein electronic relief pressure valve and step motor are installed in the casing inner chamber, step motor with electronic relief pressure valve links to each other for adjust the aperture of electronic relief pressure valve, the encoder is installed step motor is last, one side of casing with the mounting panel is fixed to be linked to each other.
Further, step motor through be provided with the speed reducer shaft coupling with electronic relief pressure valve links to each other.
Further, the encoder is an absolute type encoder.
Further, the electric pressure reducing valve is a threaded rod type electric pressure reducing valve.
Compared with the prior art, the scheme has the beneficial technical effects that: the electric pressure reducing valve device with the positioning device provided by the scheme utilizes the stepping motor to drive the electric pressure reducing valve to act, so that the opening degree of the electric pressure reducing valve is adjusted, meanwhile, the rotary angular displacement of the stepping motor is converted into a corresponding digital signal through the encoder arranged on the stepping motor, the opening degree of the electric pressure reducing valve is obtained, and the function of intelligently adjusting the flow of the electric pressure reducing valve is realized; the whole adjusting process is high in automation degree, the labor intensity of workers can be effectively reduced, and the operation efficiency is improved.
Drawings
Fig. 1 is a schematic view of the working principle and structure of the electric pressure reducing valve device of the present invention.
In the figure:
the device comprises an electric pressure reducing valve 1, an encoder 2, a stepping motor 3, a shell 4, a mounting plate 5 and a speed reducer coupler 6.
Detailed Description
The present invention will be described in further detail with reference to the drawings and the following detailed description.
This scheme is that the thread circle ratio to current relief pressure valve is more, when adjusting, operating personnel's regulation work load is great, and because the operating mode condition of system is in continuous change, the sample water flow often changes, also often need personnel to maintain the regulation, there is the trouble and the phenomenon that wastes time and energy of adjusting, and then the electronic relief pressure valve device of a tape positioning device who provides, it can drive electronic relief pressure valve with the help of step motor and carry out the aperture and adjust this electronic relief pressure valve device, accommodation process is simple swift, can effectively improve work efficiency.
Referring to fig. 1, the electric pressure reducing valve device with a positioning device in the present embodiment includes an electric pressure reducing valve 1, a mounting plate 5, a rectangular housing 4, a stepping motor 3 and an encoder 2, wherein the electric pressure reducing valve 1 and the stepping motor 3 are horizontally installed in an inner cavity of the housing 4, the stepping motor 3 is connected to the electric pressure reducing valve 1 for adjusting an opening degree of the electric pressure reducing valve 1, the encoder 2 is installed on the stepping motor 3, the encoder 2 is connected to an external control system through a signal line worn by the encoder 2 (for example, a P L C control system is adopted) for transmitting a converted digital signal to the control system, calculating an angular displacement of rotation of the stepping motor 3, and further calculating the opening degree of the electric pressure reducing valve 1.
In order to increase the output torque, the stepping motor 3 in this embodiment is connected to the electric pressure reducing valve 1 through a speed reducer coupling 6.
In addition, in order to prevent the data loss phenomenon caused by the fault due to the unexpected reason during the operation, the encoder 2 in the embodiment adopts an absolute type encoder, and it can be understood that the absolute type encoder 2 is adopted, because the reading of the output code is determined, that is, the reading of the output code at each position is unique, so that the absolute type encoder 2 is not separated from the actual position when the power supply is disconnected, and when the power supply is switched on again, the reading of the position is still current, which is effective. Preferably, the electric pressure reducing valve 1 in the present embodiment is a screw-type electric pressure reducing valve.
During operation, operating personnel sets up corresponding parameter (step motor 3 turned angle) according to the control requirement on control system (P L C), and step motor 3 rotates corresponding turned angle according to the parameter requirement of setting for, and then drives electric pressure reducing valve 1 and moves for electric pressure reducing valve 1 reaches the aperture that the system set for, has carried out corresponding pressure control, finally realizes intelligent regulation's purpose.
