One side of the small semicircular ring is arranged on the inner wall of the big semicircular ring in a spot welding mode to form a pipe joint body. The outer wall of the big semicircular ring is provided with two lugs with bolt holes. Each lug is provided with a hinge pin with holes. Connecting bolts penetrate through the bolt holes in the two lugs and the hinge pins with the holes to lock the big semicircular ring and the small semicircular ring together. A rubber ring with flangings at the two ends is arranged in the pipe joint body. Check rings, gearing rings and guide rings are arranged on the portions between the two ends of the pipe joint body and the two ends of the rubber ring. The locking type pipe joint has the advantages of being simple in structure, good in sealing effect, high in pressure resistance, high in structural strength and good in stability; in a high-pressure system, the locking type pipe joint has good sealing, pressure resisting and connecting functions.
Description
Technical field
The utility model relates to a kind of pipe joint, relates in particular to a kind of locking type pipe joint that high-rise is carried the pipe-line system of water that is applicable to.
Background technique
Pipe joint is connecting pipeline or pipeline is contained in to the part on hydraulic element in hydraulic system, is a kind of general name of the link that can install and remove in fluid passage.In pipe fitting, serving as indispensable key player, it is one of two main composition parts of hydraulic tubing.Pipe joint has various kind, and conventional pipe joint generally can be divided into two kinds of hard pipe joint and hose couplings.If the Placement according to pipe joint and pipeline is divided, hard pipe joint has three kinds of flared type, FERRULETYPE and welding types, and hose coupling is mainly fastening-pressing type rubber hose coupling.In high-pressure system, the pipe joint of connecting pipeline is owing to belonging to dismountable connecting element, it is meeting outside the requirements such as normal stable connection, sealing are strong, Sizes, the pressure loss is little, technology capability is good, also must meet dismounting requirement easily, also there is superelevation sealability simultaneously.At present, the pipe joint great majority employing FERRULETYPE in the high-pressure system on market, adopt bonded washer or O type circle to carry out the sealing work for end face.But, this traditional Placement, while there is prepackage, cutting ferrule is out of shape seriously, loses the shortcoming of seal action, thereby does not support the existence of whole high-pressure system, affects the installation of oilhydraulic engineering.
Summary of the invention
The purpose of this utility model is to provide a kind of locking type pipe joint, this locking type pipe joint is simple in structure, good sealing effect, resistance to pressure is strong, structural strength is high, and product stability is good, in high-pressure system, can play sealing, withstand voltage, linkage function well.
For achieving the above object, a kind of locking type pipe joint of the utility model, it comprises that two ends are provided with more than half annulus and the smaller part annulus of flanging, and described small semicircle ring set is embedded in more than half annulus, and one side of smaller part annulus point is welded on the inwall of big semicircle ring and forms pipe joint body; On the outer wall of described more than half annulus, be provided with two ear seats with bolt hole, on two ear seats, be respectively equipped with bearing pin with holes, connecting bolt is locked together more than half annulus and small semicircle ring by the bolt hole on two ear seats and bearing pin with holes; In described pipe joint body, be provided with the cushion rubber that two ends are provided with flanging, between the two ends of pipe joint body and cushion rubber, be provided with back-up ring, gear ring and guide collar.
Described connecting bolt is provided with two.
The outer wall that described two ends are provided with the smaller part annulus of flanging is provided with groove.
In technique scheme, due to pipe joint body be the small semicircle ring set that is provided with flanging by two ends be embedded in more than half annulus and on one side spot welding form together, therefore the diameter of pipe joint body can change arbitrarily, thereby is applicable to the head installation of different tube diameters size, saves cost; Between the two ends of pipe joint body and cushion rubber, be provided with back-up ring, gear ring and guide collar, effectively improve sealability; Equally, the two ends of large and small semicircular ring and cushion rubber are all provided with inside flanging, the surface of contact of increase and pipe fitting, thus at utmost improve sealability; By be provided with two ear seats with bolt hole on the outer wall of semicircular ring, on two ear seats, be respectively equipped with bearing pin with holes, connecting bolt is locked together more than half annulus and small semicircle ring by the bolt hole on two ear seats and bearing pin with holes, easy for installation and the overall construction intensity of product is improved, realize installation and the high voltage bearing object of high constructure pipe-line system.
