Description

 The invention relates to devices for component parts of machines, apparatuses and various structures containing pneumatic and hydraulic systems, and, above all, to devices for connecting pipes through an opening in the wall.

Known analogue, which is the connection of the outer pipe to the wall at the through hole by means of a nut with a sealing washer located on the outer side of the wall and a fastener installed on the pipe on the inner side of the wall [1]
Known pipe connections through an opening in the wall by means of adapters in the form of screw-in or straight fittings containing a central channel and sealing elements of the adapter in the wall, as well as sockets for connecting pipes to the adapter from the outer and inner sides of the wall [2]
The specified type of pipe connection is selected for the prototype.

 The technical problem to be solved consists in the need to connect the outer pipe through the same through hole in the wall both with the environment that takes place behind this wall and with the second pipe located on the inner side of the wall, with free access for the wall from the outside excluded. The possibility of access through the central channel of the adapter housing / fitting, elbow, etc. / is allowed, additionally, an electric communication line between the outer and inner sides of the wall can be used.

 However, the known types and types of pipe connections do not allow to solve the above technical problem.

 The technical result obtained by the implementation of the proposed device is to positively solve the technical problem with minimal means and while maintaining the parameters of the existing through hole in the wall.

 The essence of the invention lies in the fact that in the known connection of pipes through an opening in the wall containing an adapter in the form of a housing with a central channel and sockets for connecting pipes, as well as sealing elements of the adapter housing with a wall, a through groove is made on the inner side of the wall in the adapter housing and the movable sleeve enclosing the groove is mounted with the possibility of fixing in two positions, in one of which the groove in the adapter housing is insulated from the environment, while the element is made on the movable sleeve to the control mechanism of its position.

 The element for connecting the mechanism for controlling the position of the movable sleeve can be made inside or outside this sleeve, respectively, under a manual or remote drive.

 The presence of distinctive features from the prototype indicates the compliance with the novelty criterion, while due to the through groove in the adapter housing and the presence of a movable sleeve having an element for connecting a control mechanism, it is possible to install this sleeve in any of two fixed positions. In one of the provisions, when the movable sleeve isolates the through groove from the environment behind the wall, the outer pipe through the central channel of the adapter body is pneumatically connected to the pipe located on the inner side of the wall. In another position, when the movable sleeve does not overlap the through groove or does not completely overlap, but, for example, from one end, the outer pipe through the central channel of the adapter housing and the through groove is pneumatically connected to the environment taking place on the inner side of the wall.

 Thus, the totality of the distinguishing features already listed provides the opportunity to solve the technical problem formulated above, i.e. the proposed device allows you to connect the outer pipe through the same through hole in the wall by means of an adapter and with the environment that takes place behind this wall, and with a second pipe located on the inner side of the wall.

 The choice of connection with the environment or with the inner pipe can be provided manually / manual drive / through the central channel of the adapter housing using an element for connecting its position control mechanism, made inside the movable sleeve, and can be, for example, via an additional electrical communication line / remote drive / by means of an element for connecting a mechanism for controlling its position, made outside the movable sleeve.

 In Fig.1 shows the proposed device for connecting pipes in a position where the outer pipe is connected pneumatically with the environment taking place on the inner side of the wall, Fig.2 is the same device in the position when the outer pipe is connected with a pipe located on the inner side of the wall .

 In support of the criterion of industrial applicability, we can consider the following example of a specific implementation of the connection of pipes through a hole in the wall.

 The proposed device contains an adapter in the form of a housing A with a central channel B. In the housing A, a through groove B is made. Housing A consists of part 1 located before groove B and part 2 located behind groove B relative to wall 3. Part 1 of housing A is sealed in the wall 3 by means of a sealing ring 4 and is fastened with a threaded nut 5 through the washer 6. At the same time, nut 5 fastens part 2 of housing A coaxially with part 1. Holes 5 are made in nut 5. A movable sleeve 7 is installed in the area of groove B, which is in position depicted in 1, covers a part of the housing 1 and in position A illustrated in Figure 2, includes both part 1 and part 2. In this case, a portion of the housing 1 A sealing ring 8, while part 2 of the sealing ring 9.

 On part 1 of housing A, a socket D for connecting the outer pipe is made, and on part 2, socket E for connecting the inner pipe / the outer and inner pipes are not shown directly in FIGS.

 A thread G is made inside the movable sleeve 7. In Fig. 1, a gap I.

 The proposed device allows you to use many other options for the sealing elements of part 1 of the housing A in the wall 3, the sealing of the movable sleeve 7 on parts 1 and 2 of the housing A, sockets D and E for connecting pipes to the housing A and element G for connecting to the movable sleeve 7 of the mechanism managing her position.

 The proposed device operates as follows.

 Suppose that first of all it is necessary to connect the outer pipe to the environment that takes place on the inner side of the wall 3. To do this, before connecting the outer pipe to the socket D of the housing A through the central channel B using a technological device / manual drive / and thread G, we install a movable the sleeve 7 in the position indicated in figure 1. After performing this operation, connecting the outer pipe to the socket D, while the outer pipe through the Central channel B, the hole G, the gap And and the hole D is connected pneumatically with the environment taking place on the inner side of the wall 3.

 If it is necessary to connect the outer pipe to the inner pipe, first disconnect the outer pipe from the socket D of the housing A, and then using the same technological device and thread in the hole G, we install the movable sleeve 7 in the position indicated in figure 2. After performing this operation, we connect the outer pipe to socket D, while the outer pipe through the central channel B and hole Zh is pneumatically connected to the inner pipe connected to socket E. O-rings 8 and 9 in contact with the movable sleeve 7 isolate the central channel B from the surrounding medium taking place from the inside of the wall 3.

 It should be noted that the proposed device shown in FIGS. 1 and 2 is intended for manual control, while the function of the element for connecting the control mechanism is performed by the thread G, which is structurally made inside the movable sleeve 7.

 The proposed device allows you to perform the connecting element of the mechanism for controlling the position of the movable sleeve 7 outside this sleeve under the drive, for example, remote operation through an additional electrical communication line / not shown in figures 1 and 2 /.

 By using the present invention, it is possible to connect the outer pipe through the same hole in the wall and with the environment taking place on the inside of the wall and with the inner pipe. In this case, the specified technical problem is solved while maintaining the parameters of the hole in the wall and with minimal means, since the proposed device practically does not require any additional installation or commissioning work not only from the inside, but also from the outside of the wall.
