Abstract
The utility model provides a pressure tapping structure of an integrate self-heat-tracing throttling device. The pressure tapping structure of the integrate self-heat-tracing throttling device comprises two pressure tapping flange plates which are symmetrically arranged on two sides of a pore plate of the integrate self-heat-tracing throttling device. The pressure tapping structure of the integrate self-heat-tracing throttling device is characterized in that a first blind hole is arranged on the side of the pressure tapping flange plates, a second blind hole is arranged on a connection surface between the pressure tapping flange plates and a medium pipe, and the first blind hole is communicated with the second blind hole. Due to the fact that the first blind hole is arranged on the side of the pressure tapping flange plates and is communicated with the medium pipe through the second blind hole, the pressure tapping from the first blind hole can be achieved, so that a pressure guiding pipe and other devices can be arranged along an axis of the medium pipe. Compared with the structure where pressure is tapped from end faces of the pressure tapping flange plates, by means of the pressure tapping structure of the integrate self-heat-tracing throttling device, spaces of a medium pipe accessory are fully used, the structure is compact, and size miniaturization of the integrate self-heat-tracing throttling device is benefited.
Description
Technical field
The utility model belongs to the restriction device field, is specifically related to a kind of pressure taking structure of integrated self-adjoint thermal throttling device.
Background technology
Integrated self-adjoint thermal throttling device is a kind of novel energy-saving environment-friendly flowmeter, and this device utilizes by the heat of companion's hot object in technological process medium self, keeps differential pressure transmitter and normally measures.Popular, medium temperature can turn cold along with weather (the particularly north of China) and descend (to the heat radiation of environment), self-heated is exactly in order to prevent or stop the generation of this type of situation, medium temperature is maintained in a certain reasonable and economic scope, the self-heated expense is little, and efficient is high, comprehensive benefit good, has replaced jet chimney companion heat in increasing occasion, saved the energy, and construction install convenience, pollution-free.
The pressure of traditional integrated self-adjoint thermal throttling device all is the mode that adopts end face of flange punching pressure, the pressure pipe turning radius is large, and the part pipeline is away from this thermal source of process pipe, the weak effect of self-heated, easily produce and congeal phenomenon, this phenomenon is more obvious on the low temperature process pipeline.And the structure of end face of flange pressure can increase the volume of whole restriction device, installs for the compactness of restriction device, and miniaturization has brought difficulty.Particularly some Process Piping Construction site space is little, has brought difficulty to installation.
The utility model content
The purpose of this utility model is to provide a kind of pressure taking structure of integrated self-adjoint thermal throttling device, and the compact conformation of this pressure taking structure is convenient to realize the miniaturization of integrated self-adjoint thermal throttling device.
The utility model is achieved by the following technical solution:
A kind of pressure taking structure of integrated self-adjoint thermal throttling device comprises the pressure ring flange, and described pressure ring flange is two, is symmetricly set on the orifice plate both sides of integrated self-adjoint thermal throttling device; It is characterized in that, the side of described pressure ring flange is provided with the first blind hole, is provided with the second blind hole on pressure ring flange and the medium pipeline joint face, and the first blind hole and the second blind hole interconnect.
The utility model is by offering the first blind hole in the side of pressure ring flange, and by the second blind hole the first blind hole is communicated with medium pipeline, realized from the first blind hole pressure, thereby install all can be along the axis arranged of medium pipeline for pressure guiding pipe etc.Compare with the structure from the end face pressure of pressure ring flange, the utility model takes full advantage of the space of medium pipeline annex, and structure is compacter, is conducive to the volume miniaturization of integrated self-adjoint thermal throttling device.
Of the present utility modelly further be set to: the end of described pressure ring flange is provided with first through hole coaxial with the second blind hole, and the first through hole and the second blind hole interconnect.So arrange, can be so that realization to the processing of the second blind hole, reduces process complexity.
Of the present utility modelly further be set to: be provided with a welding plug in the first through hole.So arrange, the first through hole can be blocked, prevent the dielectric leakage in the medium pipeline.
Of the present utility modelly further be set to: the diameter of described the first blind hole is 19mm or 23mm.
Of the present utility modelly further be set to: the diameter of described welding plug is 18mm or 22mm.
Description of drawings
The structural drawing of the pressure taking structure of the integrated self-heated restriction device of Fig. 1;
The implication of each label is as follows among the figure:
Pressure ring flange-1, the first blind hole-2, medium pipeline-3, the second blind hole-4, the first through hole-5.
Embodiment
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the utility model provides a kind of pressure taking structure of integrated self-adjoint thermal throttling device, comprises pressure ring flange 1, and described pressure ring flange 1 is two, is symmetricly set on the orifice plate both sides of integrated self-adjoint thermal throttling device; The side of pressure ring flange 1 is provided with the first blind hole 2, is provided with the second blind hole 4, the first blind holes 2 on pressure ring flange 1 and medium pipeline 3 joint faces and the second blind hole 4 interconnects.So can realize from 2 pressures of the first blind hole, thereby the device such as pressure guiding pipe all can be along the axis arranged of medium pipeline.
For the ease of processing, the end of described pressure ring flange 1 is provided with coaxial the first through hole 5, the first through holes 5 and the second blind hole 4 of the second blind hole 4 and interconnects.Can be from a directly processing through hole that is communicated with medium pipeline 3, the i.e. combination of the first through hole 5 and the second blind hole 4 of end of pressure ring flange 1 when processing the second blind hole 4.
In order to prevent the dielectric leakage in the medium pipeline, after the second blind hole 4 machines, need to a welding plug be set in the first through hole, the first through hole is blocked.For the ease of processing, and increase the universal of pressure taking structure, the diameter of the first blind hole described in the present embodiment is 19mm or 23mm.The diameter of described welding plug is 18mm or 22mm.Certainly can also adopt according to concrete application scenarios other sizes.
