Abstract
An outer wire adjustable connector is composed of a pipe joint in which one end is provided with an outer thread, a pipe joint in which one end is provided with a circular shoulder, a pipe linkage outer wire and a lock nut with inner thread jacketed on the pipe joint and stopped by the circular shoulder. The pipe linkage outer wire is in an integrated connection with the other end of one pipe joint, and the other end of another pipe joint is provided with an inner thread. The outer wire adjustable connector is applied in gas and liquid pipelines in thread connection so that the consumption of the pipe linkage outer wire can be reduced. Thus, the leakage points of pipelines are reduced and the pipeline leak tightness is easy to guarantee. Especially the utility model is applied in the living gas pipelines and centralized heating pipelines of rural residents so that the safety of the use of pipelines is increased.
Description
Technical field
The utility model relates to a kind of adapter union.
Background technique
The adapter of small-bore, low pressure gas transmission, liquid-transport pipe-line is adopted mostly and is threaded, in the adapter construction of pipe laying, for the ease of the maintenance and the replacing of tube coupling, valve, pump or the equipment of pipeline from now on, pipeline closes on the appropriate position of valve, pump or equipment place and pipeline all will install union.The existing actual union of using has pipe joint, an end that the outside thread the other end has internal thread by an end to be had the annular shoulder the other end to have the pipe joint of internal thread and has the locknut that is sleeved on the pipe joint by annular shoulder backstop of the internal thread that matches with the pipe joint outside thread to constitute.Union all will be connected with valve, pump or equipment by silk outside taking over when taking over, and therefore there are two interfaces at silk two ends, two leakage points of corresponding formation outside each adapter of pipeline.The small-bore gas transmission in city, liquid-transport pipe-line for the employing nipple joint the heat supply pipeline of applying flexibly gas pipe line, central heating as the villeggiatura people's livelihood, because through walls, turn to frequent, pipeline control valve door kitchen range, radiator quantity many, that connect are big, thereby union and to take over outer silk many in the pipeline, cause that pipe leakage point is many, the sealing of pipeline is difficult to assurance.Pipeline very easily leaks in the using process, and this brings totally unfavorable influence for resident's life.The lighter influences indoor health, and weight person damages property, even personal injury accident takes place.
Summary of the invention
The purpose of this utility model is improved existing adapter union, provides a kind of pipeline that is used for nipple joint can significantly reduce the pipe leakage point, the outer silk formula union that seal for pipe joints is easy to guarantee.
The union of outer silk formula has externally threaded pipe joint, an end to have the pipe joint of annular shoulder, the locknut that is sleeved on the pipe joint by annular shoulder backstop of taking over outer silk and having an internal thread to constitute by an end, take over outer silk and be connected with a pipe joint the other end is whole, the other end of another pipe joint has internal thread.The locknut internal thread cooperates with the pipe joint outside thread and revolves rather fastening, two pipe joint ends and compress mutually, and two pipe joint interfaces are sealed.
In order to satisfy different adapter usage requirements, another structural type of outer silk formula union is, have externally threaded pipe joint, an end that the pipe joint of annular shoulder, the outer silk of two adapters are arranged and the locknut that is sleeved on the pipe joint by annular shoulder backstop that has an internal thread constitutes by an end, two take over outer silk is connected with the other end of two pipe joints is whole respectively.
Gas transmission, liquid-transport pipe-line that the union of outer silk formula is used for being threaded can reduce the consumption of taking over outer silk, thereby have reduced the leakage point of pipeline, and the sealing of pipeline is easy to guarantee.Apply flexibly especially for the villeggiatura people's livelihood and improved the Security that pipeline uses in the heat supply pipeline of gas pipe line, central heating.
Description of drawings
Fig. 1 is the whole outer silk formula union schematic representation that is connected with the outer silk of an adapter.
Fig. 2 is the whole outer silk formula movable joint structure schematic representation that is connected with the outer silk of two adapters.
Embodiment
Accompanying drawing is embodiment of the present utility model, and the utility model is not limited only to embodiment.Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 1, the outer silk formula union that integral body is connected with the outer silk of an adapter has the internal thread the other end to have externally threaded pipe joint (4), an end to have the pipe joint (2) of annular shoulder, the locknut (3) of taking over outer silk (1) and having inner screw sheath to be contained on the pipe joint by annular shoulder backstop to constitute by an end, takes over outer silk and is connected with the other end integral body of pipe joint (2).The locknut internal thread cooperates choosing to tighten with the pipe joint outside thread solid, and two pipe joint ends compress sealing mutually.
As shown in Figure 2, the outer silk formula union that integral body is connected with the outer silk of two adapters by an end have externally threaded pipe joint (7), an end have annular shoulder pipe joint (6), take over outer silk (5), take over outer silk (8) and female locknut (9) formation that is sleeved on the pipe joint by annular shoulder backstop, take over outer silk (5) and be connected, take over outer silk (8) and be connected with the other end of pipe joint (7) is whole with the other end of pipe joint (6) is whole.The locknut internal thread cooperates choosing to tighten with the pipe joint outside thread solid, and two pipe joint ends compress sealing mutually.
Claims (2)
1, a kind of outer silk formula union, there are externally threaded pipe joint, an end to have the pipe joint of annular stop shoulder, the locknut that is sleeved on the pipe joint by annular shoulder backstop that has an internal thread to constitute by an end, it is characterized in that having and take over outer, take over outer silk and be connected with a pipe joint the other end is whole, the other end of another pipe joint has internal thread.
2, a kind of outer silk formula is taken over union, there are externally threaded pipe joint, an end to have the pipe joint of annular stop shoulder, the locknut that is sleeved on the pipe joint by annular shoulder backstop that has an internal thread to constitute by an end, it is characterized in that having the outer silk of two adapters, two take over outer silk is connected with the other end of two pipe joints is whole respectively.
