Abstract
The utility model relates to a valve go-through pipe joint used for controlling the water flow comprising a build-in ball valve and a valve body, interfaces with external screw threads are arranged at the two sides of the valve body, locking screw caps with inner screw threads are arranged outside the interfaces, an inner connecting pipe connected with an outer connecting pipe is arranged inside the valve body, the utility model is characterized in that the inner connecting pipe and the interface and the valve body are an integrated structure, an O-shaped sealing ring is sleeved and arranged at the end where the inner connecting pipe is close to the ball valve, the O-shaped sealing ring and a pressing ring is arranged at the interface being close to an outer connecting port, the O-shaped sealing ring is contacted with the pressing ring. The utility model is made of nonmetal materials, and the original structure type is improved, the valve body and the interfaces adopts the integrated structure, the internal diameter of the outer connecting pipe equals to the external diameter of the inner connecting pipe which increases water flow of the outer connecting pipe, and the utilization ratio of pipes is increased, and the utility model has good sealing capacity and low manufacturing cost with easy popularization and application.
Description
Technical field
The utility model relates to water heating fittings, especially a kind of band valve straight-through type pipe joint that is used to control water yield size.
Background technique
In the water heating fittings field, pipe joint is commonly used part, especially insert with gate valve, uses more extensive, as family, office building etc., main with flow and the switch of controlling water.Present pipe joint mainly contains copper sleeve and plastic joint, and copper sleeve material exquisiteness is difficult for leaking, but processed complex, the cost height is promoted the generality deficiency, though the plastic joint low cost of manufacture, use extensivelyr, but leak easily, bring a lot of inconvenience to life.Band valve pipe joint is except sealing, valve is also had suitable requirement, guarantee that switch is smooth and easy, it is high that resistance to pressure is wanted, and these are basically by the reasonable structure decision of itself, and the band valve pipe joint of developing metal material such as a kind of rational in infrastructure, safe, non-copper is necessary.
Summary of the invention
The purpose of this utility model is the band valve pipe joint of a kind of rational in infrastructure, easy to use, good seal performance of design, and the technical solution of the utility model is so to realize:
A kind of band valve straight-through type pipe joint, comprise built-in ball valve (9) and valve body (2), valve body (2) two ends are respectively equipped with the interface (11) of band outside thread (10), the tapped lock nut of interface (11) peripheral hardware (3), be provided with the interior connecting leg (7) that links to each other with externally connected pipe (8) in the valve body (2), it is characterized in that described interior connecting leg (7) and interface (11), valve body (2) is into a single integrated structure, nearly ball valve (9) end of interior connecting leg (7) sheathed O RunddichtringO (6), the nearly external-connected port place of interior connecting leg (7) is provided with O-ring seals (4) and hold-down ring (5), and described O-ring seals (4) contacts with hold-down ring (5).
As preferably, hold-down ring (5) internal diameter is consistent with externally connected pipe (8) external diameter, and externally connected pipe (8) passes hold-down ring (5) and O-ring seals (4) is placed in interior connecting leg (7), and the inner end contacts with O RunddichtringO (6), and externally connected pipe (8) internal diameter is consistent with interior connecting leg (7) external diameter.
As preferably, O-ring seals (4) external diameter tightly is placed on externally connected pipe (8) excircle greater than interior connecting leg (7) internal diameter.
The utility model adopts nonmetallic material, has improved original structural type, and valve body and interface adopt integral structure, and spool is used and the valve body identical materials, and interface end is sealed by two O RunddichtringOs, and sealing effect is good.The externally connected pipe internal diameter is consistent with interior connecting leg external diameter, and is placed in interior connecting leg, can increase the flow of water in the externally connected pipe, has improved the utilization ratio of pipe.This kind band valve pipe joint structure is simple, good airproof performance, and low cost of manufacture is easily applied.
Description of drawings
Accompanying drawing is a kind of structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing,, the technical solution of the utility model is described in further detail by embodiment.
Embodiment: with reference to the accompanying drawings, valve body (2) two ends of band valve straight-through type pipe joint are respectively the interface (11) of band outside thread (10), interface (11) outside thread cooperates with lock nut (3), be provided with the interior connecting leg (7) that links to each other with externally connected pipe (8) in the valve body (2), interior connecting leg (7), interface (11) is into a single integrated structure with valve body (2), nearly ball valve (9) end of interior connecting leg (7) cover is installed O RunddichtringO (6), the nearly external-connected port place of interior connecting leg (7) is provided with O-ring seals (4) and hold-down ring (5), O-ring seals (4) is located at internal orifice, O-ring seals (4) is placed on the externally connected pipe (8), contacts with hold-down ring (5); Externally connected pipe (8) internal diameter is consistent with interior connecting leg (7) external diameter, the internal diameter of hold-down ring (5) is consistent with externally connected pipe (8) external diameter, O-ring seals (4) external diameter is greater than interior connecting leg (7) internal diameter, externally connected pipe (8) is passed hold-down ring (5) skill O-ring seals (4) and is placed on the interior connecting leg (7), and the inner end contacts with O RunddichtringO (6).
Use when installing, externally connected pipe (8) is placed on the interior connecting leg (7), and pass hold-down ring (5) and O-ring seals (4), contact with O RunddichtringO (6), and make O-ring seals (4) tightly be placed on externally connected pipe (8) excircle, turn lock nut (3) makes lock nut (3) compress hold-down ring (5) and O-ring seals (4), and what guarantee externally connected pipe (8) and inside connecting tube (7) closely links to each other and reach sealing effect.In like manner, install another interface of pipe joint, turn valve rod (1) opens or closes ball valve (9), thus the flow size of controlling liquid.
