Abstract

The utility model relates to a high temperature and high pressure viewing window, which is composed of a viewing window seat (8), transparent members (6), a gland bush (3), a sealing gasket (4), and a viewing mirror seat (1). The utility model regards ordinary quartz glass as the transparent members. The transparent members are installed in the viewing mirror seat so as to reduce stress between the transparent members and sealing members in the process of installation, and phenomenon that the transparent members are damaged by intrasystem high pressure is avoided. Maximum pressure which is borne by the viewing window is P=150 bar, and simultaneously, due to the adoption of pure aluminum gasket, the utility model can bear higher temperature; the temperature generally can reach about 100 DEG C.

Description

The HTHP form

The utility model belongs to chemical industry equipment accessory field, relates to a kind of form, relates in particular to a kind of form of ability high temperature and high pressure.

Form is a kind of common chemical industry equipment accessory, is to observe the necessary a kind of device of various chemical processes, and the application on chemical industry equipment is very extensive.As reactor, extraction tower etc., form generally all need be set, so that the situation that observation and grasp process are carried out.

Form generally is made of Transparent Parts and seal, and in the chemical process of general non high temperature high pressure, form is not so difficult to realize.Transparent Parts can select for use common unorganic glass or lucite as material, and seal can select for use polytetrafluoroethylene (PTFE) or rubber etc. to have certain flexible material as material.But under the condition of high temperature and high pressure, the realization of form just has certain difficulty, because common unorganic glass or lucite can not bear high pressure, and polytetrafluoroethylene (PTFE) or rubber etc. can not bear high temperature.Document " Design Strategies for Hith-Temperature, High-Pressure Optical Cells, Steven F.Rice, The 4 ^ThInternationalSymposium on Supercritical Fluid " reported a kind of form of ability high temperature and high pressure, this form adopts the material of sapphire as Transparent Parts, adopts the material of gold, silver as seal.This form can bear 100 ℃ high temperature and the high pressure of 200bar, but involves great expense the value of not applying.Therefore a kind of new form with industrial application value of developmental research is that realistic meaning is arranged very much.

The purpose of this utility model is to design a kind of cheap, simple in structure, form that can bear the high pressure of 100 ℃ high temperature and 150bar, to overcome the above-mentioned defective of prior art, satisfies people's needs.

Design of the present utility model is such:

With common quartz glass is Transparent Parts, and this Transparent Parts is installed in the visor seat, to reduce the stress between the Transparent Parts and seal in installation process, also can avoid the damage of intrasystem high pressure to Transparent Parts.

The said form of the utility model mainly is made of parts such as form seat, Transparent Parts, seal and visor seats.Below will do detailed elaboration to the utility model by accompanying drawing.

Fig. 1 is a form agent structure schematic diagram.

Among the figure:

1------visor seat

2------step one

3------gland

4------pad

5------screw thread

6------Transparent Parts

7------step two

8------form seat

Fig. 2 is the structural representation of form seat 8.

Fig. 3 is the structural representation of gland 3.

Fig. 4 is the structural representation of visor seat 1.

Fig. 5 be among Fig. 4 A-A to schematic diagram.------bowl bodies among the figure: 9

Said form seat 8 is a four-way, vertically part can be provided with screw thread or send out blue, be used for being connected with system, horizontal direction has two concentric steps, step 27 and step 1, space between step 27 and the step 1 is used to settle visor seat 1, and the inwall of step 1 is provided with screw thread 5, can with the threads engaged on the gland 3.

Said visor seat 1 is an a pair of center bowl bodies with holes 9, columniform Transparent Parts 6 of middle arrangement, the diameter of the external diameter of visor seat 1 and step 27 is close, the internal diameter of the external diameter of columniform Transparent Parts 6 and visor seat 1 is close, so that its no-float has certain spacing H, H=3-5mm between two bowl bodies 9, the thickness δ of Transparent Parts 6 is generally 10～12mm, to guarantee its mechanical strength and good light transmittance energy.

Said gland 3 is a hex bolts with holes in the middle of, and its screw thread matches with inner thread 5 on the step 1, so that fit.

Between two contact-making surfaces of Transparent Parts 6 and visor seat 1, be provided with the fine aluminium pad 4 of annular, at visor seat 1 and form seat 8, between visor seat 1 and gland 3, also be provided with the fine aluminium pad 4 of annular, to reach the effect of sealing.

The advantage of said form is very significant:

Gland 3 is used in masterpiece on the visor seat 1 when fastening visor seat 1, passes to Transparent Parts 6 then, and stress disperses, even also be difficult for when adopting common quartz glass as Transparent Parts broken; When system's internal pressure is higher, also masterpiece is used on the visor seat 1, pass to Transparent Parts 6 then, stress is disperseed, therefore, said form can bear higher pressure.Evidence, the maximum pressure that this visual window can bear are P=150bar; Simultaneously,, therefore can bear higher temperature, generally can reach about 100 ℃ owing to adopted the pad of fine aluminium.

Said window structure is simple, is easy to make, and is specially adapted to the tubular reactor under the high pressure-temperature condition.
