The invention relates to household and industrial gas units and is designed to protect the gas supply systems in emergency situations, such as off gas in case of fire.

Known safety drive unit with fusible link (U.S. patent 4503675, CL F 16 To 17/40, 1985). The known device has an energy storage device and the movable drive element, move to the specified position of the energy accumulator when the temperature of the environment. The bearing element has a fuse box from a material, the temperature of which is considerably less than the melting temperature of the bearing member. Bearing element selectively comes in contact with a driving member and prevents movement of the latter under the action of the energy accumulator, while the insert is in the solid state. Adjustable element connected with a drive element that moves with him from one position in which the actuator mates with bearing ale is ipodnova element after fusion insert. The known device protects the pipeline in case of fire or other emergency situations, but its design is cumbersome and complicated.

Also known automatic thermoclean for U.S. patent 5472008, CL F 16 To 17/40, 1995 Known automatic thermoclean includes a housing, a cavity which has the shutter is spring-loaded and is equipped with a stopper and a fusible link.

The disadvantage of thermoclean is the variation in the temperature of the valve opening.

Closest to the invention to the technical essence and the achieved result is termorazdelitelnymi valve according to patent US 5477877 A, class F 16 To 17/38, 26.12.1995, which includes a housing, a cavity which is made circular hole with a through hole mounted in the cavity of the housing opposite bore holes of the shutter in the form of a ball spring-loaded and is equipped with temperature-sensitive latch that is located in a through hole of the housing, and the rod retainer is introduced into contact with the ball to keep it in its original position by means of the stopper with an eccentricity relative to the axis of the bore hole.

Specified known termorazdelitelnymi valve ensures the stability of the reaction is related to ethnological execution of its body, as to secure the retainer threaded through the housing bore must be performed stepwise or with a large wall thickness. Thickening of the hull in the area of the holes needed for sealing clamp at its surfaces, and this leads to additional costs in the manufacture of thermoclean in General.

The objective of the invention is to eliminate this drawback by eliminating the thickening of the body, which reduces the intensity Ternopiloblenergo valve simplifies the process of its manufacturing and technology termination of a mortgage release.

The technical result is achieved by the fact that in thermoproteales valve, comprising a housing, a cavity which is made circular hole with a through hole mounted in the cavity opposite bore holes of the shutter in the form of a ball spring-loaded and is equipped with temperature-sensitive latch that is located in a through hole of the housing, and the rod retainer is introduced into contact with the ball to hold in the initial position with the stopper bolt eccentrically relative to the axis of the bore hole, a retainer in the form of glass with threads on the outer surface and the clamp on the t is the point, between the bottom of the glass and the free end of the rod has a temperature sensitive cylinder and the outside of the housing on the glass nevernot cap. The technical result is also achieved when performing Ternopiloblenergo valve, comprising a housing, a cavity which is made circular hole with a through hole mounted in the cavity opposite bore holes of the shutter in the form of a ball spring-loaded and is equipped with temperature-sensitive latch that is located in a through hole of the housing, and the rod retainer is introduced into contact with the ball to hold in the initial position with the stopper bolt eccentrically relative to the axis of the bore hole, the retainer is made in the form of a threaded fitting with a clamp on the end, and the socket is opened in the through hole from the inside of the body cavity and the collar placed in the annular bore, when this threaded area of the nozzle is located outside the housing and provided with a cap between the plate and whose free end of the rod has a temperature sensitive cylinder.

The invention is illustrated by drawings, where Fig.1 shows the proposed termorazdelitelnymi valve in section; Fig.2 is a cross section along a-a in Fig. 1; Fig. 3 - element term is pacak conventionally not shown); in Fig.4 - pin in the form of fitting, in section on an enlarged scale; Fig.5 is a view In Fig.3 and 4; Fig.6 - element thermoclean - thrust washer of Fig.7 - cross section C-C in Fig.6.

Termorazdelitelnymi valve includes a housing 1, a cavity 2 which is made annular bore 3 with a through hole 4. In the cavity 2 opposite the bore hole 5 of the housing 1 has a shutter in the form of a ball 6, which is loaded by a spring 7 and is provided with heat-sensitive lock 8. The latch 8 is located in a through hole 4. The stem 9 of the pawl 8 is introduced into contact with the ball 6 to hold it to its original position by means of the stopper 10 with eccentricity e relative to the axis 11 of the bore hole 5. The stopper 10 and the retainer 8 are diametrically opposed relative to the ball 6 in the annular bore 3. The stopper 10 is made in the form of a washer with an open trapezoidal neckline. The latch 8 is made in the form of glass (see Fig.3) threaded on the outer surface and the collar 12 at its end. The glass opened in the through hole 4 from the inside of the cavity 2 of the housing 1 and the collar 12 is placed in the annular bore 3. Outside the housing 1 on a glass nevernot cap 14. When this sealing glass is either installing it on glue, or by using a face pack is sa 1 and the cap 14. Between the bottom of the glass and the free end of the rod 9 has a temperature sensitive cylinder 15, collapsing at a certain temperature, for example, firms JOB GmbH, Kurt Fischer Str.30.D-22926, Ahrenburg-Hamburg, US-Patent 4.938.294.

The latch 8 may be made in the form of a threaded fitting (see Fig.4) with clamp 12 on the end. The collar may be made circular or polyhedral. The fitting routine in the through hole 4 from the inside of the cavity 2 of the housing and the collar 12 is placed in the annular bore 3. Located outside the housing section 13 of the fitting is plugged by a cap 14. When this sealing fitting is either installing it on glue, or by using a mechanical seal, for example, copper deformable washer 20 that is installed between the respective surfaces of the housing 1 and the cap 14.

Termorazdelitelnymi valve is equipped with a support washer 16 with flexible legs 17, providing the ability to enter it into the cavity 2 of the housing 1 and then jammed, and the Central frame 18, the centering spring 7.

In order for the latch 8 does not rotate during Assembly, the collar 12 is a 19 inch, mating Assembly with the annular wall of the bore 3 of the housing 1.

Termorazdelitelnymi valve operates as follows. In the original (open) human 10 with eccentricity e relative to the axis 11 of the bore hole 5 of the housing 1, not blocking it. In emergency situations, for example when the temperature around the valve, and then in the valve, the latch 8 releases the ball 6. This is because thermosensitive cylinder 15 of the latch 8 is destroyed. When the rod 9 is in the bore of the retainer 8 and the force that kept the ball 6 is reduced. This allows the ball 6 to shift with decreasing eccentricity and move under the action of the spring 7 in the open trapezoidal neckline puck-stopper 10 to overlap the bore hole 5 of the housing 1. The valve is closed, and the ball 6 is held by the force of the spring 7 and the pressure of the working environment.

Thanks to the use of thermosensitive cylinder 15 in the design Ternopiloblenergo valve stabilization of a reaction temperature and a more rapid actuation of the valve by placing thermosensitive cylinder 15 is partially outside the housing.

In addition, the embodiment of the casing of the proposed valve thickening over the annular bore does not require high precision manufacturing latch under the injection (as in the prototype) and, therefore, increases the manufacturability and reduced the price of the valve manufacturer.

The supply of the latch means from proevo bore.

After the establishment of the latch from the inside of the body cavity into the hole on the side wall of the availability of funds from turning (the flats) facilitates Assembly of the valve, as it does not require special tools to hold the lock when tightening the cap.

The present invention can be used wherever you need emergency auto overlapping bore pipelines, including pipelines in emergency situations, such as a fire, while simplifying the design and manufacture Ternopiloblenergo valve.
