Technical Field

The invention relates to the technical field of flowmeters, in particular to a leakage-free high-temperature-resistant throttling device.

Background

the development of flow measurement can be traced back to ancient hydraulic engineering and urban water supply systems. The ancient Roman Kaiser times have used orifice plates to measure the amount of drinking water for residents. The flow of Nile river was measured by the weir method in ancient Egypt about 1000 b.c. before the Gongyuan. The water level of the bottleneck is observed by the famous water conservancy project of the Dujiang weir in China. The flow meters are classified into differential pressure type flow meters, rotameters, throttle type flow meters, slit flow meters, volumetric flow meters, electromagnetic flow meters, ultrasonic flow meters, turbine flow meters, vortex shedding flow meters, and the like. Liquid flow meters, gas flow meters, steam flow meters, and solid flow meters are classified by media.

Because the flowmeter contains throttling element, gets pressure flange, sealed pad, draws and presses pipe, three valves mount pad, straight tube section, assembles or welds at industrial field, and the quality is difficult to guarantee, and there is the hidden danger of revealing in the sealed position, awaits improving urgently.

Disclosure of Invention

the invention aims to provide a leakage-free high-temperature-resistant throttle with reasonable design aiming at the defects and shortcomings of the prior art, wherein an interception original piece, a straight pipe section, a pressure introduction pipe and a mounting seat are welded into a whole, nondestructive detection is carried out, the leakage hidden danger caused by using a sealing gasket is avoided, the quality is effectively ensured, and the practicability is higher.

In order to achieve the purpose, the invention adopts the following technical scheme: the three-valve-group pressure pipe comprises a straight pipe section, a throttling element, a pressure guiding pipe, a three-valve-group mounting seat and a flange; the throttling element is welded and fixed inside the straight pipe section, the pressure guiding pipes are welded and fixed outside the straight pipe section, and the pressure guiding pipes are arranged corresponding to the installation positions of the throttling element; the upper end of the pressure guiding pipe is welded and fixed on the lower surface of the three-valve group mounting seat; flanges are welded at the left and right ports of the straight pipe section.

Furthermore, the plurality of pressure guiding pipes are arranged on the straight pipe sections on the left side and the right side of the throttling element in a bilateral symmetry mode.

After adopting the structure, the invention has the beneficial effects that: the invention provides a leakage-free high-temperature-resistant throttling device which integrates an interception original piece, a straight pipe section, a pressure leading pipe and a mounting seat, performs nondestructive testing, avoids leakage hidden danger caused by using a sealing gasket, effectively ensures the quality and has stronger practicability.

Fig. 1 is a schematic structural view of the present invention.

Description of reference numerals:

The device comprises a straight pipe section 1, a throttling element 2, a pressure leading pipe 3, a three-valve-group mounting seat 4 and a flange 5.

the specific implementation mode is as follows:

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1, the following technical solutions are adopted in the present embodiment: the three-valve-group pressure pipe comprises a straight pipe section 1, a throttling element 2, a pressure guiding pipe 3, a three-valve-group mounting seat 4 and a flange 5; a throttling element 2 is fixedly welded inside the straight pipe section 1, two pressure guiding pipes 3 are fixedly welded outside the straight pipe section 1, and the two pressure guiding pipes 3 are arranged corresponding to the installation positions of the throttling element 2; the upper end of the pressure guiding pipe 3 is welded and fixed on the lower surface of the three-valve group mounting seat 4; flanges 5 are welded at the left and right ports of the straight pipe section 1.

Further, two pressure leading pipes 3 are arranged on the straight pipe sections 1 on the left and right sides of the throttling element 2 in a bilateral symmetry manner.

The working principle of the specific embodiment is as follows: through welding process with straight tube section 1, throttling element 2, pressure pipe 3, three valves mount pad 4 and flange 5 welding as an organic whole, and after the welding is accomplished, carry out nondestructive test, saved the setting of sealed pad, effectively solve because of the ageing problem of revealing that brings of sealed pad.

After adopting above-mentioned structure, this embodiment's beneficial effect is: this embodiment provides a no leakage high temperature resistance throttle, and it will hold back original paper, straight tube section, draws and presses pipe, mount pad welding as an organic whole to nondestructive test avoids using the hidden danger of revealing that sealed the pad brought, and its quality is effectively guaranteed, and the practicality is stronger.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
