Description
Technical field
This utility model belongs to vacuum drainage field, particularly relates to a kind of vacuum valve attachment structure to vacuum line air hatch.
Background technology
Current outdoor drainage system mainly adopts gravity system, and user side sewage, by the gravity pipe line laid under road direction, is flowed to lower by eminence under terrestrial gravitation effect.It is simple that gravity drainage system has construction, the advantages such as operation expense is relatively low, but is subject to landform restriction, and excavated volume is big, and ground failure is strong.Therefore, vacuum drainage technology comes into the visual field of people just gradually in recent years, and vacuum pipe is laid and do not needed the gradient, applied widely, reduces cutting depth, saves construction space and capital construction cost.Its operation principle is: when liquid level reaches predetermined altitude, pilot valve is switched to vacuum interface, is connected with vacuum line by vacuum valve, and work chamber air is sucked away, under the atmospheric pressure of medium inlet, and vacuum break valve.
Existing vacuum valve directly bundlees connection to connected mode many employings vacuum hose of air hatch, and this results in the easy play of flexible pipe when vacuum suction, and the two ends of flexible pipe also can depart from from operating position sometimes, affects the normal use of people.
In addition, owing to vacuum line needs to consider the corrosivity of sewage, therefore many selection UPVC materials, flexible pipe is then plastic hose, how under ensureing bubble-tight condition, both materials are connected to become in more reliable manner a great problem of puzzlement those skilled in the art.
Utility model content
For overcoming the problems referred to above, this utility model provides a kind of vacuum valve to the attachment structure of vacuum line air hatch, solves existing mode and connects insecure, the problem of the easy play of flexible pipe.
This utility model solves its technical problem and be the technical scheme is that a kind of vacuum valve attachment structure to vacuum line air hatch, including the flexible pipe being connected with vacuum valve, it is arranged on the first T-connecting piece of air hatch, the outlet of two, the left and right of this first T-connecting piece connects vacuum line respectively, exit, top is sealedly connected with the first pipeline, the other end of the first pipeline is provided with reducing, this reducing is connected to the second T-connecting piece by the first joint, one outlet of this second T-connecting piece is connected to plug or manometer, another outlet is docked with aforementioned flexible pipe mutually by the second joint.For convenience of maintenance time test pressure, on the second T-connecting piece can Bonding pressure instrument, at ordinary times under non-inspecting state, can install plug so that ensure system air-tightness.
As another embodiment of the present invention, between reducing and the first joint, it is additionally provided with second pipe.The effect of this second pipe is in that to extend the vertical height of gas circuit, it is prevented that the sewage in vacuum line flows under pressure into flexible pipe.
Above-mentioned first pipeline, reducing and second pipe all extend vertically upwards layout, it is so designed that and can prevent sewage in vacuum line from flowing backwards into the vacuum interface place of pilot valve, realize gas-liquid separation, further, the outlet being connected with flexible pipe on described second T-connecting piece, arranges with the exit normal being connected with the first joint on the second T-connecting piece.
As a kind of concrete connected mode of the present invention, the two ends of above-mentioned first joint are equipped with external screw thread, reducing and be equipped with the interior tooth suitable with external screw thread on the second T-connecting piece；Second joint is Quick-insertion type pipe joint.In addition for improve sealing further, it is additionally provided with fluid sealant or sealing ring in the junction of above-mentioned each pipe fitting.
Further, vacuum line adopts UPVC material to make, and its nominal pressure is more than 1.0MPa；First T-connecting piece, the first pipeline and reducing all adopt UPVC material to prepare, and the first joint, the second joint and the second T-connecting piece adopt rustless steel or copper material to prepare.
It is contemplated that the corrosivity of sewage, vacuum line is mostly UPVC material, and flexible pipe is plastic material, therefore how the flexible pipe on vacuum valve is connected in more reliable more firmly mode with the air hatch of vacuum line, becomes a great problem of puzzlement those skilled in the art.Vacuum line and the first pipeline are attached by the first T-connecting piece that the present invention is prepared by UPVC material, UPVC reducing is installed in the upper end of the first pipeline, then pass through the first joint and connect above-mentioned UPVC reducing and rustless steel or copper material makes the second T-connecting piece, after, connect the flexible pipe vacuum interface to pilot valve through the second joint.The air hatch of above-mentioned first pipeline is arranged on the top of vacuum line, can reduce sewage and flow into the possibility of pilot valve vacuum interface on source.In addition above-mentioned first pipeline, reducing, second pipe are arranged vertically upward, air pressure in its concrete high visibility vacuum line and set, prevent sewage from flowing backwards further.It addition, the outlet being connected with flexible pipe on the second T-connecting piece, arrange with the exit normal being connected with the first joint on the second T-connecting piece, and then further avoid sewage to enter the vacuum interface of pilot valve.Below with reference to drawings and Examples, this utility model is described in detail.
