Abstract
The utility model relates to a lap welding intermediate nipple, in particular to a lap welding intermediate nipple being suitable for O-shaped rubber ring seal. The utility model aims to solve the problems that a copper washer is complicated to process and the engineering cost is high because the copper washer is adopted to carry out seal when the traditional lap welding intermediate nipple and a square shoulder joint are connected, and an external force is difficult to control, the leakage is easy to generate or part of intermediate nipple is easy to damage in the pipeline construction process. The lap welding intermediate nipple being suitable for the O-shaped rubber ring seal comprises a nipple body; the coupling end of the nipple body and the square shoulder joint is provided with a circular bead, and the end surface of the circular bead is provided with an O-shaped rubber ring placement channel. The lap welding intermediate nipple is widely applied to all industrial fields that fluid needs to be transmitted through pipelines, such as the industrial fields of shipboard automation, food automation, industrial automation and the like and is especially suitable for the pipeline coupling in oil, water and gas systems of which the pressure is lower than 16MPa.
Description
Technical field
The utility model relates to a kind of joint welding intermediate thread joint, is specifically related to the joint welding intermediate thread joint of a kind of suitable O shape seal with elastometic washer.
Background technique
Being connected between the pipe that joint welding intermediate thread joint is used for needs dismountings and the pipe.At present, when the joint welding intermediate thread joint of CB56 standard is connected with flat shoulder grafting head, generally adopt asbestos packing sheet or copper washer to seal.Asbestos packing sheet can discharge toxic gas, is not suitable for using at this confined space of boats and ships, and use progressively has been under an embargo; The copper washer processed complex, the engineering cost height, and in the pipeline construction process, need apply bigger external force and make copper washer generation plastic deformation, thereby reach the effect of sealing, when the workmen exerts oneself when too small or inhomogeneous, can cause the insufficient of seal washer plastic deformation or take place crookedly, leakage phenomenon often takes place; Firmly excessive as the workmen, can cause the damage of transition joint helical thread portion.
The model utility content
The purpose of this utility model is to be connected the copper washer processed complex that adopts the copper washer sealing to exist with flat shoulder grafting head in order to solve existing joint welding intermediate thread joint, the engineering cost height, and external force control is difficult in the pipeline construction process, be prone to the problem of leaking or causing the damage of transition joint helical thread portion, and then the joint welding intermediate thread joint of a kind of suitable O shape seal with elastometic washer is provided.
The technical solution of the utility model is: the joint welding intermediate thread joint that is suitable for the seal with elastometic washer of O shape comprises joint body; The connecting end of joint body and flat shoulder grafting head is provided with shoulder, has O shape rubber ring on the end face of described shoulder and lays conduit.
The utility model compared with prior art has following effect: the utility model is laid conduit by offer O shape rubber ring on joint body, realized adopting between joint welding intermediate thread joint and the flat shoulder grafting head O shape rubber ring to seal, O shape rubber ring has replaced traditional copper washer, reduced engineering cost, the required external force of O shape rubber ring generation resiliently deformable is less, avoid the appearance of leakage phenomenon, also avoided the damage of transition joint helical thread portion simultaneously.Joint welding intermediate thread joint of the present utility model is widely used in boats and ships, food, industrial automation etc., and all need carry out the industrial field of fluid transmission by pipeline.The utility model is particularly useful for during pipeline in the Oil, Water, Gas system that pressure is lower than 16MPa connects, and is more than 1.6 times of intermediate thread joint sealing pressure rating of CB56 standard.
Description of drawings
Fig. 1 is overall structure master's sectional view of the present utility model, and Fig. 2 is the left view of Fig. 1, and Fig. 3 is the A place partial enlarged drawing of Fig. 1, and Fig. 4 is that the utility model is applied to the main sectional view in the pipeline connection.
Embodiment
Embodiment one: present embodiment is described in conjunction with Fig. 1-Fig. 4, the joint welding intermediate thread joint of the suitable O shape seal with elastometic washer of present embodiment comprises joint body 1, joint body 1 is provided with shoulder 1-1 with the connecting end of flat shoulder grafting head 2, has O shape rubber ring on the end face of described shoulder 1-1 and lays conduit 1-2.
Embodiment two: in conjunction with Fig. 1 and Fig. 4 present embodiment is described, the end face of the shoulder 1-1 of present embodiment is 2mm to the distance H that is connected between the end face of joint body 1 and flat shoulder grafting head 2.So be provided with, be convenient to joint welding intermediate thread joint and be connected with flat shoulder grafting head 2.Other composition is identical with embodiment one with annexation.
Embodiment three: in conjunction with Fig. 3 present embodiment is described, the O shape rubber ring of present embodiment is laid between the end face of the sidewall of conduit 1-2 and shoulder 1-1 and is rounded down, and fillet R is 0.2mm.The installation of being convenient to O shape rubber ring so is set.Other composition is identical with embodiment one or two with annexation.
When joint welding intermediate thread joint of the present utility model is applied to the pipeline connection, be one at first with joint welding intermediate thread joint and first pipeline 3 overlap joint and assembly welding, flat shoulder grafting head 2 and second pipeline, 5 overlap joints and assembly welding are one, O shape rubber ring 6 is installed in O shape rubber ring lays in the conduit 1-2, utilize cap nut 4 that joint welding intermediate thread joint and flat shoulder grafting head 2 are linked together.
