Abstract

The utility model belongs to the technical field of unions and in particular discloses an outer screw union. The utility model adopts the technical scheme that the outer screw union comprises a screw head, a female union and a male union, wherein an insertion external thread is arranged at one end of the screw head; a convex ring is adjacent to the other end of the screw head; a connection internal thread and a first external thread are respectively arranged at two ends of the male union; one end of the screw head, which is provided with the convex ring, is inserted into one end of the male union, which is provided with the first external thread; a female union internal thread which is matched with the first external thread is arranged inside the female union; and the female union is connected with a male union thread. During installation, one end of the connection internal thread of the male union is connected with the input end, the screw head is inserted into the external thread and directly connected with water consumption equipment, and the female union is screwed. The outer wire union has the advantages that parts such as screws are eliminated during the installation of the union, cost is reduced, a required construction space during the installation is small, an occupation space after the installation is small, simplicity and convenience in construction are realized, installation efficiency is improved, daily maintenance is facilitated, and a good sealing effect is achieved.

Description

Outer silk is by appointing

Technical field

The utility model belongs to the pipe fitting technical field, and particularly a kind of outer silk is by appointing.

Background technique

Install or other pipeline connection areas at hot-water heating, between each subtube and radiator, heat exchanger or other water device, need use by times being connected.Use at present by leaving in structural reason, by appointing two ends need link to each other with pipeline to silk, therefore use existing technology to have drawback with the pipeline junction: one of which, use workpiece many, cost increase, and take with the construction space requirement big; Its two, each workpiece joint is caused the hidden danger of leaking easily; Its three, working procedure is loaded down with trivial details, causes installation efficiency low, installation cost increases; Its four, operational maintenance and regular maintenance difficulty.

The model utility content

The technical problem that the utility model solves just provide a kind of simple installation, good seal performance, the installing space that needs and take up room little, with low cost, daily maintenance is simple and convenient and the outer silk of delicate appearance by appointing.

For solving the problems of the technologies described above, the technological scheme that the utility model adopts is:

Comprise silk head, by female and by public affairs; The first end of said silk is provided with the insertion outside thread; Be provided with bulge loop at its other end of silk head, said two ends by public affairs are respectively arranged with accepts the internal thread and first outside thread, and said galon has an end of bulge loop to insert saidly to have first outside thread, one end by public affairs; Said by female inboard be provided with said first outside thread coupling by female internal thread, saidly be connected by male thread with said by female.

Its supplementary features:

Be provided with sealing gasket at the bulge loop of said silk head with between by Gongzhi.

The utility model provided outer silk has the following advantages by appointing to compare with existing technology: one of which, the first end of said silk is provided with the insertion outside thread, can be directly and radiator, heat exchanger or the connection of other water device.After the bulge loop of its other end setting of silk head puts sealing gasket, insert and saidly have first outside thread, one end by public affairs.Said by female inboard be provided with said first outside thread coupling by female internal thread; Said by mother overlap the silk rolling head block the silk bulge loop outer rim be connected by public first outside thread with said; To be connected with input end by the end that public affairs are accepted internal thread, will be screwed by mother then gets final product.This installation has reduced at present by appointing when installing the use of parts such as silk, save an outer silk with by times connection procedure, reduced cost; During installation construction need the space little and also install after take up room little; It is easier to construct, and improves installation efficiency, makes daily maintenance convenient; Its two owing to be provided with sealing gasket, further improved sealing effect at the bulge loop of said silk head with between by Gongzhi.

Description of drawings

Fig. 1 for the utility model provided outer silk by the cross-sectional view of appointing.

Embodiment

Below in conjunction with accompanying drawing and specific embodiment the outer silk that the utility model provided is done further detailed description by the structure of appointing.

As shown in Figure 1, this outer silk comprises silk 1 by appointing, by female 2 with by public 3, an end of silk 1 is provided with and inserts outside thread 11; Near near its other end, be provided with bulge loop 12, the two ends by public 3 are respectively arranged with accepts internal thread 31 and first outside thread 32, and the end that silk 1 has bulge loop 11 inserts an end that is had first outside thread 32 by public affairs 3; By female 2 inboards be provided with first outside thread 32 coupling by female internal thread 21; By female 2 be threaded by public affairs 3, during installation, will be connected with input end by the end that public affairs are accepted internal thread 31; The insertion outside thread 11 of silk 1 directly is connected with watering equipment or pipe collar, will screws by female 2 then.Reduced at present by appointing when installing, reduced cost the use of parts such as silk, during installation construction need the space little and also install after take up room for a short time, to construct easier, the raising installation efficiency make daily maintenance convenient, and sealing effect is better.

Be provided with sealing gasket 4 at the bulge loop 12 of silk 1 with between, further improved sealing effect by public 3.

Just to the explanation of the utility model, therefore, the protection domain of the utility model not only is confined to the foregoing description to the foregoing description, as long as structure is identical by appointing with the outer silk of the utility model, just drops on the scope of the utility model protection.

Claims

1. outer silk is characterized in that by appointing: comprise the silk head, by female and by public affairs, the first end of said silk is provided with the insertion outside thread, is being provided with bulge loop near its other end; Said two ends by public affairs are respectively arranged with accepts the internal thread and first outside thread; Said galon has an end of bulge loop to insert saidly to have first outside thread, one end by public affairs; Said by female inboard be provided with said first outside thread coupling by female internal thread, saidly overlap the silk rolling head by mother and block the bulge loop outer rim and be connected by public first outside thread with said.

2. outer silk according to claim 1 is characterized in that by appointing: be provided with sealing gasket at the bulge loop of said silk head with between by Gongzhi.
