Abstract
The utility model relates to a liquid relief pipe, which comprises a circulating pipeline, an inlet flange which is arranged at the outer side of an inlet of the circulating pipeline, and an outlet flange which is arranged at the outer side of an outlet of the circulating pipe; a slender hole is arranged in the circulating pipeline; the entry section of the slender hole is an entry transitional conical hole, and an exit section of the slender hole is an exit transitional conical hole; and the diameter of the slender hole is smaller than 10mm, and the length of the slender hole is 1800mm to 3500mm.Due to the adoption of the liquid relief pipe, the technical problem that the present liquid decompression device cannot adapt to the decompression requirement of high-pressure and high-temperature liquid medium can be solved. Due to the adoption of the liquid relief pipe, the liquid containing solid particles such as coal powder and the like can be prevented from abrading and corroding the pipeline.
Description
Technical field
The utility model relates to the liquid relief pipe in a kind of chemical industry or other industrial production.
Background technique
In chemical industry or other industrial production, need carry out the operation controls such as reduction, partial throttling of pressure to the liquid medium of technology link, with the requirement of the operational condition that adapts to subsequent processing.That is, liquid medium makes the state of liquid medium that certain change (state herein mainly refers to: pressure, and other parameters of being followed by pressure, as flow velocity, rate of depreciation etc.) take place by a certain specific device.
But can finish above apparatus operating one and be directly subordinate to the wear-resistant equipment of decompression that uses on " vacuum area " (that is, not having this kind equipment, structure disunity) even the common engineering all seldom.Along with large-scale, the high temperature of chemical engineering industry, the development of high pressure, urgent need can adapt to the liquid relief pipe of complex working condition (pressure is higher, high temperature, serious wear, aggressive medium).
Summary of the invention
The utility model purpose provides a kind of liquid relief pipe, to solve the technical problem that existing liquid decompressor can't adapt to high pressure, high-temp liquid medium decompression demand.
Technical solution of the present utility model is:
A kind of liquid relief pipe, its special way is: it comprises circulation duct 1, be arranged on the inlet outside of circulation duct 1 inlet flange 2, be arranged on the outlet(discharge) flange 3 in the outlet outside of circulation duct 1; Be provided with elongated hole 12 in the described circulation duct; The entrance of described elongated hole 12 is inlet transition taper hole 11, and the outlet section of described elongated hole 12 is outlet transition taper hole 13; The diameter of described elongated hole is less than 10mm, and the length of described elongated hole is 1800～3500mm.
Above-mentioned elongated hole cooperates the deep hole processing drill gun to form through the air protection welding by three to four sections stainless steel sections.
Above-mentioned stainless steel is a two phase stainless steel.
Technique effect of the present utility model is:
1, because liquid is very high by intermediate section decompression back flow velocity, be ejection at a high speed, directly enter the inner member that subsequent processing may impact the upstream device wall or damage upstream device, so a changeover portion is set, promptly export tapered channel, conveniently dock with subsequent processing, make fluid stable continuous-flow, also weaken the discontinuous mechanical shock that produces in flow of fluid interface equipment itself is reached the damage that connecting tube causes, changeover portion also can be other shapes and looks like rectangle, but taper is the shape face of the most stable gradually changeable.When the bigger liquid of pressure entered elongated hole, the pressure of liquid went up, and flow velocity reduces, and the force value of its rise also is the force value much smaller than entrance point after enlarging by conical outlet.
2, the utility model select for use corrosion resistance preferably two phase stainless steel can prevent to contain pipe wear and corrosion that the liquid of solid particles such as coal dust causes as circulation duct.
3, the utility model can be saved manufacture cost.Do not considering under the condition of cost that the utility model also can whole oval excellent forging Vehicle Processing cooperate deep hole processing to finish, and saves the link of welding, promptly is no butt weld.If consideration manufacture cost, elongated hole preferably cooperate the deep hole processing drill gun to form through the air protection welding by three to four sections stainless steel sections.With two phase stainless steel is that comprehensive price ratio is best; If when considering that manufacture cost or liquid medium are highly purified water or purer non-corrosive medium, can use common stainless steel.
Description of drawings
Fig. 1 is the utility model structural representation;
Reference character is as follows: 1-circulation duct, 11-inlet transition taper hole, 12-elongated hole, 13-outlet transition taper hole, 2-inlet flange, 3-outlet(discharge) flange.
Embodiment
A kind of liquid relief pipe, it comprises circulation duct 1, be arranged on the inlet outside of circulation duct 1 inlet flange 2, be arranged on the outlet(discharge) flange 3 in the outlet outside of circulation duct 1; Be provided with elongated hole 12 in the described circulation duct; The entrance of described elongated hole 12 is inlet transition taper hole 11, and the outlet section of described elongated hole 12 is outlet transition taper hole 13; The diameter of described elongated hole is less than 10mm, and the length of described elongated hole is 1800～3500mm.
Above-mentioned elongated hole cooperates the deep hole processing drill gun to form through the air protection welding by three to four sections stainless steel sections.
Above-mentioned stainless steel is a two phase stainless steel.
Be applied to the relief pipe of liquid operating mode, (actual application operating mode is: discharge water to contain solid particle in the liquid; Contain millimetre-sized pulverized coal particle in the water, particle is many planar band wedge angle, and hardness causes pipe wear serious more greatly; Sulfur-bearing and byproduct of reaction in the coal dust or in the discharge water, corrosivity is bigger), because satisfy the requirement of subsequent processing speedup step-down, through Structure Calculation, this equipment circulation inner diameter less (10mm is following), length according to the about 2.0m of process parameter that regulates requirement such as flow, pressure to (adding upper inlet transition taper hole and export the length of transition taper hole) between the 3.5m.
Structurally can adopt wear-resistant ceramic as circulation passage, (key is a longer dimension but pottery difficulty when making is big, if use the multistage group to meeting cause the joint have step promptly be can not guarantee coaxial), and the working medium band presses (3.8MPa even higher) and pressure to fluctuate, and pottery lacks necessary toughness; In the transportation instrumentation, damage easily.
Consider above reason and condition; practical application for stainless steel (selecting corrosion resistance two phase stainless steel preferably for use) overall structure (can divide three, four sections weldings) according to length overall; cooperate deep hole processing equipment (drill gun; usually can finish the processing of a 1.7m; different according to pore diameter size), the air protection welding can be finished the manufacturing of product.
No matter be ceramic structure or all metal construction, the pattern of this equipment all is that entrance end is the transition taper that is connected with external pipe, and the centre is the minor diameter elongated hole.
