Description
Technical field
The invention belongs to transmitter mounting technique field, and in particular to a kind of fixed mechanism of teletransmission pressure transmitter.
Background technology
In nuclear power station, it is necessary to be situated between during the medium easily crystallized using the pressure transmitter measurement with remote transmitting diaphragm seal
Increase heat-barrier material between matter and the installing plate of instrument calibration, to prevent the medium in the remote transmitting diaphragm of transmitter from crystallizing to the cold.Such as
Shown in Fig. 1, traditional mounting means is 4 holes (tapping) of brill on the outer flange end face of the remote transmitting diaphragm of pressure transmitter,
The installing plate 2 of flange and instrument calibration 1 is fixed with bolt, between the two using asbestos insulation material.As shown in figure 4, existing use
The centre for the asbestos heat-insulation layer that asbestos are made is provided with 4 through holes of Φ 12,4 holes being installed to by sunk screw on end face of flange
On, peripheral four bolts hole are used to install with the installing plate 2 of instrument calibration 1.Asbestos are the insulation materials commonly used in nuclear power station, but
Its hardness is not high, and after flange and installing plate are fastened with bolt, asbestos heat-insulation layer can be thinning, influences heat insulation effect, and antivibration
Kinetic force is not strong；Further, since additionally to be drilled on the flange of transmitter, such transmitter is non-standard de-sign, it is necessary to factory
Family's particular design, and the bearing capacity of flange may be influenceed.
The content of the invention
For defect present in prior art, it is an object of the invention to provide a kind of fixation machine of teletransmission pressure transmitter
Structure, the fixed mechanism have a good insulation and vibrationproof performance, and installation cost is low.
To achieve the above objectives, the technical solution adopted by the present invention is：A kind of fixed mechanism of teletransmission pressure transmitter, institute
The teletransmission seal assembly that teletransmission pressure transmitter includes being located at transmitter measurement end is stated, teletransmission seal assembly includes flange and sealing
Membrane for pressure measurement in the side end face of flange one, the fixed mechanism include being used for the instrument calibration for carrying teletransmission seal assembly,
Instrument calibration is provided with prominent installing plate, and bakelite plate, flange and the electricity of teletransmission seal assembly are connected with the installing plate of instrument calibration
Plank is connected.
Further, multiple bolts hole for being connected with flange are provided with the center of bakelite plate, the outer of bakelite plate is provided with
Multiple bolts hole for being connected with wedge-shaped installing plate.
Further, to be square, the bolt hole at the center of bakelite plate is centrally located on same circumference bakelite plate, and
The axis of symmetry of the line and bakelite plate at the center of each bolt hole at the center of bakelite plate and the center of bakelite plate is in 45 degree
Angle.
Further, the side of bakelite plate is provided with the hole for being deep into the center.
The present invention is from the material that intensity is big and the bakelite of good heat insulation is as thermal insulation board, and the material is high except hardness, insulation
Property it is well outer, also meet the low cigarette of nuclear power plant's material, Halogen, it is fire-retardant the characteristics of, during installation, it is only necessary to drilled on bakelite plate, respectively
For with instrument calibration, flange installation, it is only necessary to 4 lengthening bolts flange is fixed with bakelite, have good insulation with
Vibrationproof performance.In this programme, instrument flange need not drill, and avoid damaging the mechanical structure of flange, influence its pressure-bearing
Ability, so as to improve the safety and reliability of instrument, in addition, equipment belongs to standardized product, reduce purchase cost.

Embodiment
The invention will be further described with reference to the accompanying drawings and detailed description.
As shown in figure 1, the invention provides a kind of fixed mechanism of teletransmission pressure transmitter, wherein the teletransmission pressure becomes
Device is sent to include the teletransmission seal assembly 4 for being located at transmitter measurement end, teletransmission seal assembly 4 includes flange and is sealed in flange side
Membrane for pressure measurement in end face.
As shown in figure 1, the fixed mechanism of teletransmission pressure transmitter provided by the invention includes being used to carry teletransmission sealing group
The instrument calibration 1 of part 4, instrument calibration 1 are provided with installing plate 2, bakelite plate 3, the flange of teletransmission seal assembly 4 are connected with installing plate 2
It is connected with bakelite plate 3.Bakelite plate 3 plays heat-insulated and installation fixation.
As shown in Figure 2,3, multiple bolts hole (for example, number is 4, a diameter of Φ 11) are provided with the center of bakelite plate 3.Far
Passing the flange of seal assembly 4 can be fixed by Lengthened bolt and bakelite plate 3.The outer of bakelite plate 3 can be provided with multiple bolt hole (examples
