Abstract
The utility model discloses a railway wagon pipe joint which comprises a first joint body, a second joint body and a connecting part which enables the first joint body and the second joint body to be connected, wherein a dust filtering net is arranged between the first joint body and the second joint body. According to the railway wagon pipe joint, a non-sealed pipe thread is adopted, a leakage is prevented, a vehicle brake failure can be avoided, and the requirements of effective connections of railway wagon brake parts and pipelines and an interchange between a pipe joint which is used in an existing railway wagon for Commonwealth of Independent States (CIS) can be met. Due to the fact a nut is made of stainless steel materials, service life is prolonged, and performance is more reliable. In addition, the filtering net in the joint can filter impurities in the air during the period of vehicle braking or remission.
Description
Technical field
The utility model relates to a kind of railway freight-car pipe joint.
Background technique
At present, the accessories such as domestic rail wagon brake system master cylinder, storage reservoir, air shut-off valve, empty and load brake equipment are very ripe with the interconnection technique of pipeline, and promulgated with the form of standard, obtain at home batch on railway freight-car and use.
What adopt due to the pipe joint in domestic existing railway wagon brake is the sealing tapered thread, can not satisfy member country of the Commonwealth of Independent States's railway wagon brake pipe and brake the effective of accessory and be connected; Domestic existing pipe joint can't be realized vehicle filtration of impurity in air between braking or paracmasis; Joint cast iron nut is short working life, poor-performing.
Because member country of the Commonwealth of Independent States's rail wagon brake system is different from China accepted standard, interconnection technique is also different; The existing railway freight-car of member country of the Commonwealth of Independent States uses and the exchange requirement of pipe joint so the braking accessory of China railways Freight Car Braking System and the interconnection technique of pipeline can not satisfy.
The model utility content
The technical problems to be solved in the utility model is to provide a kind of railway freight-car pipe joint, the utility model railway freight-car pipe joint adopts the non-tight pipe thread, anti-leak, can avoid car brakeing malfunctioning, can satisfy member country of the Commonwealth of Independent States's railway wagon brake accessory and reach and the exchange requirement that has railway freight-car pipe joint used now effective connection of pipeline; The stainless steel nut increases the service life, more reliable performance; Filter screen in joint can filter vehicle airborne impurity between braking or paracmasis.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of railway freight-car pipe joint comprises the first fittings body, the second fittings body and the link that the first fittings body and the second fittings body are coupled together; Be provided with dust filter net between the first fittings body and the second fittings body.
Link is the stainless steel nut, and described nut and the first fittings body thread bush connect in succession, and are threaded with the second fittings body.
The cross section of dust filter net is parabola shaped, and dust filter net is fixed on the second fittings body.
Be provided with sealing gasket between the first fittings body and the second fittings body.
The first fittings body and the second fittings body adopt the non-tight pipe thread.
The beneficial effect that adopts technique scheme to produce is: the utility model railway freight-car pipe joint adopts the non-tight pipe thread, anti-leak, can avoid car brakeing malfunctioning, can satisfy member country of the Commonwealth of Independent States's railway wagon brake accessory and reach and the exchange requirement that has railway freight-car pipe joint used now effective connection of pipeline; The stainless steel nut increases the service life, more reliable performance; Filter screen in joint can filter vehicle airborne impurity between braking or paracmasis.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
1 is the first fittings body, and 2 is the second fittings body, and 3 is the stainless steel nut, and 4 is dust filter net, and 5 is sealing gasket.
Embodiment
A kind of railway freight-car pipe joint comprises the first fittings body 1, the second fittings body 2 and the link that the first fittings body and the second fittings body are coupled together; Be provided with dust filter net 4 between the first fittings body 1 and the second fittings body 2;
Link is stainless steel nut 3, and nut and the first fittings body 1 thread bush connect in succession, and are threaded with the second fittings body 2;
The cross section of dust filter net 4 is parabola shaped, and dust filter net 4 is fixed on the second fittings body 2;
Be provided with sealing gasket 5 between the first fittings body 1 and the second fittings body 2;
The first fittings body and the second fittings body adopt the non-tight pipe thread.
The utility model railway freight-car pipe joint is applicable to Mongolia rail wagon brake line system, is mainly used in pipeline and is connected with master cylinder, storage reservoir, air shut-off valve, the effective of empty and load brake equipment.Adopt the utility model pipe joint, can solve the connectivity problem of member country of the Commonwealth of Independent States's railway wagon brake pipe and braking accessory, assemble simple and convenient, workable, improve production efficiency and product quality.
In the utility model pipe joint, the first fittings body and the second fittings body can adopt the non-tight pipe thread, can satisfy the General Requirement of pipe joint in member country of the Commonwealth of Independent States's rail wagon brake line and exchange requirement.And the employing of the pipe joint in domestic existing railway wagon brake is the sealing tapered thread, can not satisfy member country of the Commonwealth of Independent States's railway wagon brake pipe is connected with the effective of connectivity problem of braking accessory, be easy to occur leaking, cause car brakeing malfunctioning, more can not realize the exchange performance of pipe joint.
Dust filter net in the utility model pipe joint can be realized the vehicle function that in air, impurity is filtered between braking or paracmasis.
