Description
Technical field
The present invention relates to railway vehicle plumbing sanitary equipment technical field, be specifically related to a kind of vaccum stop valve for railway vehicle toilet.
Background technique
This railway vehicle toilet vaccum stop valve, is applicable to Chinese different kinds of railways vehicle bathroom appliances and project.
Railway vehicle toilet is communicated with the external world by pipeline, thus realize the discharge of sewage, but railway vehicle is when running at high speed, because Venturi effect can produce negative pressure at entrance place, and then the suction-operated produced inside, toilet, in order to stop that this absorption strength is to the destruction of toilet, needs to install vaccum stop valve on pipeline.
Stop valve on the existing railway vehicle of China, the bend pipe structure all adopted, although serve isolated ambient air, takes up room when installing, is also unfavorable for maintenance and repair simultaneously.
Summary of the invention
The object of the invention is to provide a kind of vaccum stop valve for railway vehicle toilet, to solve many defects that prior art deficiency causes.
A kind of vaccum stop valve for railway vehicle toilet, comprise valve gap, valve body, leather cup, angle coupling, gland and rubber duck-bill, the two ends up and down of described valve body and side are equipped with opening and are interconnected, described gland bolt is connected to the upper end of valve body, described leather cup is connected to the opening of valve body side, valve gap is installed on leather cup, fastening by angle coupling clamping between valve gap and leather cup, and described rubber duck-bill to be located in valve body and to be communicated with the opening of valve body upper end.
Preferably, described rubber duck-bill comprises funnel shaped cavity and is connected to the body of cavity bottom, and body is in closed state in its natural state.
Preferably, described duckbilled rubber is specifically made up of ethylene propylene diene rubber.
Preferably, described valve gap is provided with a vent.
Preferably, described valve gap, valve body, angle coupling and gland are made by high-strength nylon material.
Preferably, the top of described gland is connected with the flange body with mounting hole.
Preferably, the outer surface of upper of described gland is provided with one section of outside thread, and the gland outer surface bottom outside thread is provided with limiting board.
The invention has the advantages that: the present invention is directed to the requirement that railway vehicle runs, realize vehicle static, can smooth discharge sewage, vehicle, when high-speed mobile produces negative pressure, can effectively completely cut off air and enter vehicle toilet, simultaneously, product structure is simple, rationally distributed, be easy to installation and removal, be conducive to later maintenance and maintenance.

Embodiment
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the present invention further.
As shown in Figures 1 to 5, a kind of vaccum stop valve for railway vehicle toilet, comprise valve gap 1, valve body 2, leather cup 3, angle coupling 4, gland 5 and rubber duck-bill 6, two ends up and down and the side of described valve body 2 are equipped with opening and are interconnected, described gland 5 bolt is connected to the upper end of valve body 2, described leather cup 3 is connected to the opening of valve body 2 side, valve gap 1 is installed on leather cup 3, fastening by angle coupling 4 clamping between valve gap 1 and leather cup 3, described rubber duck-bill 6 to be located in valve body 2 and to be communicated with the opening of valve body 2 upper end.
It should be noted that, the body 62 that described rubber duck-bill 6 comprises funnel shaped cavity 61 and is connected to bottom cavity 61, body 62 is in closed state in its natural state, described duckbilled rubber 6 is specifically made up of ethylene propylene diene rubber, described valve gap 1 is provided with a vent 7, and described valve gap 1, valve body 2, angle coupling 4 and gland 5 are made by high-strength nylon material.
Working principle of the present invention is specially: 1, stationary vehicle, during toilet sewage effluent, sewage flows into stop valve through car interior conduit in vaccum stop valve upper end gland 5, when current flow through rubber duck-bill 6, under flow action, rubber duck-bill 6 bottom is softened, and sewage flows along valve body 2 interior conduit, under the stop of leather cup 3, finally flow out outside car through valve body 2 end opening, 2, during vehicle high-speed motion, negative pressure is produced at vaccum stop valve end opening place, air flows to leather cup 3 through valve body 2 interior conduit, deformation can be there is to valve gap 1 direction at atmospheric pressure effect down cup 3, and gas between the two can be discharged by the vent 7 on valve gap 1, prevent leather cup 3 stress deformation and damage, when after leather cup 3 deformation, air can continue upwards to flow along valve body 2 interior conduit, until when moving to rubber duck-bill 6, because rubber duck-bill 6 is flat, and opening is very little, can regard as and be in closed state, ambient atmos cannot move up again, thus toilet is played a protective role.
In the present embodiment, duckbilled rubber 6 fatigue strength be made up of ethylene propylene diene rubber is high, long extrusion-deformation repeatedly can be born and do not occur damaging, long service life, ensure that the normal work of device, and described valve gap 1, valve body 2, angle coupling 4 and gland 5 are made by high-strength nylon material, under the prerequisite meeting structural strength, avoid the situation that corrosion easily appears in metallic material.
As improvement project of the present invention, as shown in Figure 4, the top of described gland 5 is connected with the flange body 8 with mounting hole, be connected with the waste pipe of toilet by flange body, soundness is good, easy for installation, or, as shown in Figure 5, be provided with one section of outside thread 9 in the outer surface of upper of gland 5, gland 5 outer surface bottom outside thread 9 is provided with limiting board 10, is threaded with the waste pipe of toilet by gland 5, soundness is also better, and easy for installation.
Based on above-mentioned, the present invention is directed to the requirement that railway vehicle runs, realize vehicle static, can smooth discharge sewage, vehicle is when high-speed mobile produces negative pressure, can effectively completely cut off air and enter vehicle toilet, meanwhile, product structure is simple, rationally distributed, be easy to installation and removal, be conducive to later maintenance and maintenance.
As known by the technical knowledge, the present invention can be realized by other the embodiment not departing from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, is not only.Within the scope of the present invention all or be all included in the invention being equal to the change in scope of the present invention.
