Abstract
The utility model discloses a high-temperature resistant vacuum suction pipe joint for the connection of hard pipes, which comprises a fixed joint and a movable joint. The utility model is characterized in that the outer walls of the fixed joint and the movable joint are sheathed with a pressing ring; one end of the movable joint presents a lug boss shape; conical surface sealing rings are arranged among the movable joint, the fixed joint, and the pressing ring. The utility model has the advantages of simple structure, good tightness, and simple and rapid operation. The utility model also has the advantages that the service life of pipes can be prolonged; the operational reliability of pipes can be guaranteed; the pipes which can meet the temperature condition within 80-90 DEGC can be normally used.
Description
The utility model belongs to pipe joint, is meant that especially a kind of hard tube connects the heat resisting and pressure resisting vacuum draw pipe joint of usefulness.
Molding machine hot pressing counterdie in the pulp molding complete sets of equipment taking out, inhaling on goods transfer and two stations of thermocompression forming, its with vacuum pipe between the conventional flexible pipe that adopts down be connected, but because hunting frequency height between two stations, amplitude are big, actual in addition the use under 80 ℃～90 ℃ temperature conditions, flexible pipe very easily produces aging and is caused leakage by jackknifing.
The purpose of this utility model is to solve the shortcoming of above-mentioned existence, provides a kind of good seal performance, long service life, assembling easy, and can satisfy the fixedly heatproof vacuum draw pipe joint that equidistantly do not connect between two stations of the other end of vacuum pipe one end.
The purpose of this utility model takes following measure to realize:
The utility model adopts that an end is fixed, an end can rotate around the pipe fitting center line, adopt the design proposal of conical surface seal between two pipe joints, be that described heatproof vacuum draw pipe joint comprises permanent joint, union, round nut, retainer ring are set between permanent joint and union, the first end of loose joint is arranged to the boss shape, and the conical surface seal circle is set between union, permanent joint and retainer ring.
Specific embodiments of the present utility model as shown in drawings
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the structural representation of retainer ring of the present utility model
Fig. 3 is the structural representation of seal ring of the present utility model
Embodiment elaborates to the utility model below in conjunction with accompanying drawing:
Among the figure: 1. permanent joint 2. unions 3. retainer rings 4. seal rings 5. round nuts
Embodiment with reference to the accompanying drawings:
The utility model pumping tube is made up of permanent joint 1, union 2, retainer ring 3, seal ring 4, round nut 5 with heatproof vacuum draw pipe joint.The end that union 2 is connected with permanent joint 1 is arranged to boss shape, permanent joint 1, union 2 overcoat retainer rings 3, and fastening by round nut 5.2 of permanent joint 1 and unions, union 2 and 3 of retainer rings are provided with conical surface seal circle 4 respectively.Seal ring 4 adopts the contour performance sealing material of nylon to make.The connecting tube period of the day from 11 p.m. to 1 a.m is as long as tighten after twining with teflon seal tape according to conventional silk mouthful pipeline.
Structural design of the present utility model compared with prior art has following advantage: adopt this The articulation of utility model design is applicable between hard tube to connect; This articulation can be around the pipe fitting center Line rotate and sealing reliable, thereby satisfy vacuum pipe one end fixedly the other end two stations it Between equidistantly do not connect; Adopt the high nylon of heat resistance as sealing member material in the articulation, And as sealing surface, have stronger wear-resisting, heat resistance, so that the utility model with the conical surface Have higher service life and sealing property, the vacuum pipe leak rate is reduced greatly; Improve The operational reliability of the complete set of equipments such as pipe fitting, the fault rate of minimizing equipment.
Claims (3)
