Abstract
The inlaid jacket foot valve for the convenience of unloading material, it mainly unloads chemical crystallizations under normal temperature. It forms an enclosed barricading layer close to the feeding valve under the major flange and the exposed major part, with connecting channels between the separated layers with welded intake and outlet pipes at the beginning and ending of the device. When unload the material, vapor enters through the intake pipe, melts the crystallization with the smooth open of the valve. Extra vapor returns from the through channel with the outlet. It solves the problem of normal temperature bottom valve opening for unloading crystallization chemicals with storage tank vehicles, makes it possible for transporting oils with high viscosity. It is very practical.
Description
Technical field
Belong to chemical medium transportation technology and valve mechanism technical field.
Background technique
Along with the development of China's chemical industry, the transportation of chemical medium has a large capacity and a wide range, and the tank car transport volume of various chemical product is increasing, comprising the tank car transportation of crystal chemistry product under a large amount of normal temperature.The crystal chemistry product characteristic is just to have crystallization to separate out when a certain temperature (about 180 ℃) is following under the normal temperature, progressively becomes crystallization by liquid state and condenses.When it fills transportation in tank car; tank body has thermal insulation layer to guarantee that chemical product is in liquid state; and be installed on the built-in bottom valve of discharging bottom the tank car owing to be connected with the discharge pipe that exposes and can't be incubated; the exposed parts of its valve body is under the normal temperature; and because the vehicle movement rapid heat dissipation, so the material at its valve seat place condenses with regard to crystallization.When tank car arrived the destination and needs discharging, blocking up with regard to the chemical product of do not open bottom valve or crystallization can't blowing at the valve port of opening, and often will take measures, and wasted time and energy and dangerous.
Summary of the invention
The present invention is the chemical product that crystallization under a kind of accumulating normal temperature will be provided, the embedded jacket foot valve of energy easy-unloading.
The technological scheme that the present invention takes: the chemical product of crystallization under a kind of accumulating normal temperature, the embedded jacket foot valve of energy easy-unloading, comprise the blowing valve body that links to each other with valve body master flange, its scheme is: around the blowing valve body under adjacent main flange with the main body section of outer exposure, all enclose a sealing interlayer, there is siphunculus to connect between the interlayer that separates, and is welded with inlet tube and outer pipe respectively at top and end.The sealing interlayer is that blowing valve body top is with inner chamber, and blowing valve body middle and lower part shell has the chuck parcel, has connecting tube to join between inner chamber and chuck, at inner chamber inlet tube is arranged, and chuck has outer pipe.
The good effect of implementing behind the present invention is, during discharging, steam imports from inlet tube, and part in addition in valves such as steam inner chamber heating valve seat dissolves crystallization, thus the discharging of smooth opening valve.Excess steam is from the steam (vapor) outlet connected loop.Solve the problem that crystal chemistry product storage tank car bottom valve under the normal temperature can opening for unloading, and created condition for the tank car transportation of high viscosity oil product under the normal temperature etc.
