Abstract
The utility model relates to a boiler and pressure vessel-used manhole with an internal pressure auto-self-tightening seal structure. The utility model is characterized in that the manhole is internal pressure trepanning reinforced type, a casing is welded with the manhole reinforced component, a clamp is arranged in a ring groove of the manhole reinforced component, a sealing ring is fixed supported by the clamp through a supporting ring; a manhole cover is in contact seal with the sealing ring, and that a baffle plate is connected with the manhole cover by bolts. The utility model has the advantages of simple and rational structure, safe use, reliability of sealing, low material consumption, low cost, and convenient processing and manufacturing, installation and maintenance.
Description
The utility model is the improvement to the hand-hole structural design on boiler and the various pressurized container, relates to the interior pressure self-tightening sealing formula hand-hole of a kind of boiler, pressurized container.
At present, domestic structural design to the pressurized container hand-hole on boiler and various storage tank, the tank car adopts hubbed flange and many high-strength bolts, nut usually, attachment weld between its adapter and hubbed flange need carry out radiographic inspection, also exist bolt easily to get rusty and problems such as the expense material of taking a lot of work, this project organization complexity, sealing effect are unreliable, not only wasted man-hour and material, brought trouble to maintenance.
The purpose of this utility model is to provide the boiler of pressing the self-tightening sealing structure in a kind of employing the, the interior pressure self-tightening sealing formula hand-hole of pressurized container for the pressurized container on boiler and various storage tank, the tank car.
The interior pressure self-tightening sealing formula hand-hole content Description of the utility model boiler, pressurized container:
The utility model boiler, the interior pressure self-tightening sealing formula hand-hole of pressurized container, it is characterized in that: press in the self-tightening sealing structure in a kind of the employing to press off hole reinforcement formula hand-hole, housing and hand-hole stiffener weld together, on the inwall of hand-hole stiffener, annular groove is set, one card key is assemblied in the annular groove of hand-hole stiffener, on card key endless belt is a bracing ring, the top of bracing ring is a seal ring, clean-out plate is pressed on the seal ring, bolt passes spring washer and is connected with clean-out plate, baffle plate is connected by bolt with clean-out plate, and baffle plate can be annular slab or blind plate form.
The interior pressure self-tightening sealing formula hand-hole of the utility model boiler, pressurized container is pressed in the self-tightening sealing structure in a kind of the employing and is pressed off hole reinforcement formula hand-hole, and its project organization is simple, reasonable, and container inner pressure high sealing pressure more is big more, and sealing effect is good more; Can select the material and the shape of seal ring according to different media, temperature, pressure rank, overcome shortcomings such as present general boiler, pressurized container hand-hole waste material, complex structure, sealing effect be unreliable.Have safe in utilization, sealing is reliable, save raw material, reduce cost, be convenient to manufacturing and installation, the characteristics of convenient maintenance.
Embodiment:
Fig. 1 is the interior pressure self-tightening sealing formula hand-hole structural representation of boiler, pressurized container
The interior pressure self-tightening sealing formula hand-hole of the utility model boiler, pressurized container is to realize like this, press in the self-tightening sealing structural formula in a kind of the employing and press off hole reinforcement formula hand-hole, see Fig. 1, housing 9 welds together with hand-hole stiffener 1, on the inwall of hand-hole stiffener 1, annular groove is set, lateral expansion that can the reinforced seal circle, the enhanced leaktightness effect; One card key 8 is assemblied in the annular groove of hand-hole stiffener 1, is a bracing ring 7 on card key 8 endless belt, and the top of bracing ring 7 is seal rings 2, and clean-out plate 3 is pressed on the seal ring 2, and clean-out plate 3 contacts and seals with seal ring 2; Bolt 5 passes spring washer 6 and is connected with clean-out plate 3, and baffle plate 4 is connected by bolt 5 with clean-out plate 3; Baffle plate 4 can be annular slab or blind plate form; Clamping bolt 5 makes clean-out plate 3 compress seal ring 2 to reach sealing effect, and for preventing that ponding from entering in the container, baffle plate 4 is changed into the blind plate form of not perforate by annular slab when baffle plate 4 is installed in the top of container.When pressing increase in the container, internal pressure is consistent with the force direction that causes the seal ring lateral expansion, has strengthened sealing, presses the effect of self-tightening sealing in forming.
