Background technique
This rolling stock toilet vaccum stop valve is suitable for Chinese different kinds of railways vehicle bathroom appliances and project.
Rolling stock toilet is communicated with the outside world by pipeline, thus realize the discharge of sewage, but rolling stock is in height When driving, because Venturi effect can generate negative pressure at entrance, and then generation is to the suction-operated inside toilet for speed, In order to stop destruction of this absorption strength to toilet, need that vaccum stop valve is installed on pipeline.
Shut-off valve on the existing rolling stock in China, the bend pipe structure all used, although playing isolation outside air, Occupied space when being installation, while being also unfavorable for maintenance and repair.
Summary of the invention
It is an object of that present invention to provide a kind of vaccum stop valves for rolling stock toilet, to solve the prior art not Many defects caused by foot.
A kind of vaccum stop valve for rolling stock toilet, including valve deck, valve body, leather cup, angle coupling, gland and rubber Duckbilled, the upper and lower ends of the valve body and side, which are equipped with, to be open and is interconnected, and the gland bolt is connected to the upper of valve body End, the leather cup are connected to the opening of side of valve body, and valve deck is installed on leather cup, are clamped between valve deck and leather cup by angle coupling Fastening, the rubber duck-bill are set in valve body and are connected to the opening of valve body upper end.
Preferably, the rubber duck-bill includes funnel shaped cavity and the tube body for being connected to cavity bottom, and tube body is in nature Closed state is under state.
Preferably, the duckbilled rubber is specifically made of ethylene propylene diene rubber.
Preferably, the valve deck is equipped with a venthole.
Preferably, the valve deck, valve body, angle coupling and gland are made of high-strength nylon material.
Preferably, the flange body with mounting hole is connected at the top of the gland.
Preferably, the outer surface of upper of the gland is equipped with one section of external screw thread, sets on the gland outer surface of external screw thread bottom There is limit plate.
The present invention has the advantages that the present invention is directed to the requirement of rolling stock operation, realize that vehicle static, can be arranged smoothly Sewage is put, vehicle can effectively completely cut off air and enter vehicle toilet when high-speed mobile generates negative pressure, meanwhile, product structure letter It is single, it is rationally distributed, it is easy to install and remove, is conducive to later maintenance and maintenance.

Specific embodiment
To be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below with reference to Specific embodiment, the present invention is further explained.
As shown in Figures 1 to 5, a kind of vaccum stop valve for rolling stock toilet, including valve deck 1, valve body 2, skin Bowl 3, angle coupling 4, gland 5 and rubber duck-bill 6, the upper and lower ends of the valve body 2 and side, which are equipped with, to be open and is interconnected, described Gland 5 is bolted to the upper end of valve body 2, and the leather cup 3 is connected to the opening of 2 side of valve body, and valve deck 1 is installed to leather cup 3 On, between valve deck 1 and leather cup 3 by angle coupling 4 clamping fastening, the rubber duck-bill 6 be set to valve body 2 in and with 2 upper end of valve body Opening connection.
It is worth noting that, the rubber duck-bill 6 includes funnel shaped cavity 61 and the tube body for being connected to 61 bottom of cavity 62, tube body 62 is in closed state in its natural state, and the duckbilled rubber 6 is specifically made of ethylene propylene diene rubber, the valve Lid 1 is equipped with a venthole 7, and the valve deck 1, valve body 2, angle coupling 4 and gland 5 are made of high-strength nylon material.
The working principle of the invention specifically: 1, stationary vehicle, when toilet sewage effluent, sewage is through interior pipeline from true Shut-off valve is flowed into empty shut-off valve upper end gland 5, when water flow flows through rubber duck-bill 6, under flow action, under rubber duck-bill 6 Portion is softened, and sewage is flowed along 2 interior conduit of valve body, under the blocking of leather cup 3, is finally flowed out outside vehicle through the lower mouth of valve body 2;2, vehicle When high-speed motion, negative pressure is generated at mouth under vaccum stop valve, air flows to leather cup 3 through 2 interior conduit of valve body, in atmospheric pressure masterpiece With down cup 3 can deformation occurs to 1 direction of valve deck, and the venthole 7 on valve deck 1 gas between the two can be discharged, and prevent Only 3 stress deformation of leather cup and damage, after 3 deformation of leather cup, air will continue to flow up along 2 interior conduit of valve body, until movement When to rubber duck-bill 6, because rubber duck-bill 6 is flat, and it is very small to be open, and can regard as in closed state, ambient atmos It can not move up again, to play a protective role to toilet.
In the present embodiment, 6 fatigue strength of duckbilled rubber made of ethylene propylene diene rubber is high, can bear prolonged anti- Multiple to be squeezed and deformed without damaging, long service life ensure that the normal work of device, and the valve deck 1, valve body 2, angle coupling 4 and gland 5 be made of high-strength nylon material, under the premise of meeting structural strength, avoid metal material and be easy to appear The case where corrosion.
Scheme as an improvement of the present invention, as shown in figure 4, the top of the gland 5 is connected with the flange with mounting hole Body 8 can be connected by the drainpipe of flange body and toilet, and fastness is good, easy for installation, alternatively, as shown in figure 5, in gland 5 Outer surface of upper be equipped with one section of external screw thread 9,5 outer surface of gland of 9 bottom of external screw thread is equipped with limit plate 10, passes through gland 5 It is threadedly coupled with the drainpipe of toilet, fastness is also preferable, and easy for installation.
Based on above-mentioned, the present invention is directed to the requirement of rolling stock operation, realize vehicle static, can smooth discharge sewage, Vehicle can effectively completely cut off air and enter vehicle toilet when high-speed mobile generates negative pressure, meanwhile, product structure is simple, layout Rationally, it is easy to install and remove, is conducive to later maintenance and maintenance.
As known by the technical knowledge, the present invention can pass through the embodiment party of other essence without departing from its spirit or essential feature Case is realized.Therefore, embodiment disclosed above, in all respects are merely illustrative, not the only.Institute Have within the scope of the present invention or is included in the invention in the change being equal in the scope of the present invention.
