Abstract
The utility model provides a locking non-return combination valve. A locking valve portion and a non-return valve portion are in sealing butt joint through case butt-joint ends of the two valve portions. The two outer ends are provided with pipeline connecting joints. According to the technical scheme, the locking function and the non-return control function are combined into one, and the locking non-return combination valve has the technical advantage of simplifying the pipeline installation operation, and can effectively reduce the hidden danger of leakage possibly caused by pipeline connection.
Description
Technical field
The utility model relates to the control valve that liquid conducting pipes is installed and used.
Background technique
The such as liquid conducting pipes such as heat supply pipeline, tap water conveyance conduit, needs the control valve arranging to mainly include locking valve and check valve etc.On a lot of conveyance conduits, connection locking valve, also need the installation check valve that is connected except wanting, the unnecessary loss of carrying liquid backflow to cause when avoiding locking valve not close.But existing locking valve and check valve are all absolute construction products, need independent operation, with pipeline connection separately, fitting operation is comparatively loaded down with trivial details, also can exist and leak improperly hidden danger because of attended operation.
Summary of the invention
Goal of the invention of the present utility model is that only carrying out once mounting operation with pipeline is connected and has both locking and check control and a kind of locking check combination brake switch and proporting is provided, and simplifies pipeline connection and operates.The locking check combination brake switch and proporting technological scheme that the utility model provides, its main technical content is: a kind of locking check combination brake switch and proporting, be made up of locking valve portion and check valve portion, locking valve portion docks through two valve portion housing butt end sealings with check valve portion, and two outer ends are external pipe jointing.
The locking check combination brake switch and proporting technological scheme that the utility model provides, is combined into one locking functions and check control function, greatly facilitates pipeline fitting operation, has also effectively reduced pipeline and has connected the leakage hidden danger that may occur.
Accompanying drawing explanation
Fig. 1 is appearance assumption diagram of the present utility model.
Fig. 2 is cut-open view of final assembly of the present utility model.
Embodiment
The disclosed locking check of the utility model combination brake switch and proporting, it is constructed as shown in drawings, mainly includes locking valve portion 1 and check valve portion 2, and locking valve portion 1 docks and connects and composes through the sealing of the butt end of two valve portion housings 10,20 with check valve portion 2.In this enforcement structure, the butt end of the butt end of check valve portion 2 and locking valve portion 1 is respectively internal and external threads sealing docking, should make two valve portions not only have same pipeline center line after connection, and two valve portion valve body center lines are parallel to each other and in the same plane.The inner side nozzle diameter of check valve portion 2 internal thread butt ends is not less than locking valve portion 1 outside thread butt end nozzle diameter, both preferably approach until identical, and the end face 23 of the inner side mouth of pipe reaches the surface accuracy being sealed and matched, both can guarantee the seal rubber pad 22 of check baffle plate 21 and the identical sealing of the end face of the inner side mouth of pipe 23 of check valve portion 2, and the pipeline discharge value of the two valve portions of assurance is consistent.Two outer ends of locking valve portion 1 and check valve portion 2 arrange pipe connector lug 14,24.
