Abstract
The invention belongs to a matched rat-proof device of a sewer pipe network, and the matched rat-proof device can solve the rat pollution problem of an existing sewer pipe. The matched rat-proof device comprises an outer barrel used for being connected with the opening of the sewer pipe and an inner frame used for being connected with a drainage exit of a water consuming utensil, wherein a one-way valve is mounted at the bottom of the inner frame, and the inner frame is sleeved with the outer barrel. The one-way valve comprises a tongue plate which is mounted at a water outlet in the bottom of the inner frame through a torsion spring. According to the matched rat-proof device, due to the fact that the one-way valve is mounted at the bottom of the inner frame, when water in the water consuming utensil falls down, the water pushes the one-way valve open through gravity, drainage is not influenced, the water outlet in the bottom of the inner frame is sealed by the one-way valve when water is not drained, and rats can not enter a room through the inner frame.
Description
Technical field
The invention belongs to technical field of buildings, particularly the improvement of downcomer net.
Background technology
Existing sewer pipe is connected the connection of employing flexible pipe with washbowl, tank etc., often have mouse chew off flexible pipe and enter indoorly, and particularly the sewer pipe of the public place such as school, hospital, cause cross pollution.
Summary of the invention
The present invention seeks to design the supporting Mouseproof device of a kind of downcomer net, to solve existing downcomer mouse pollution problem.
Specifically, the supporting Mouseproof device of downcomer net, it comprise urceolus for being connected with sewer pipe mouth with for being connected the internal frame of water appliance discharge outlet, the internal frame bottom is equipped with check valve and is enclosed within urceolus.Described check valve comprises a hyoplastron, and hyoplastron is contained in internal frame bottom delivery port with torsion spring.
The present invention, owing in the internal frame bottom, check valve being housed, relies on gravity to push check valve open when water falls in water appliance, do not affect draining, check valve sealing internal frame bottom delivery port during not draining, and mouse can't enter from internal frame indoor.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 be in Fig. 1 A to view.
Fig. 3 is inner rack structure schematic diagram in the present invention.
Fig. 4 be in Fig. 3 B to schematic diagram.
Embodiment
Be the specific embodiment of the invention as shown in Figure 1-2.The supporting Mouseproof device of downcomer net, it comprises urceolus 4 for being connected with sewer pipe mouth and internal frame 2 for being connected the water appliance discharge outlet, internal frame 2 bottoms are equipped with check valve and are enclosed within urceolus 4.Described check valve 3 comprises a hyoplastron 3, and hyoplastron 3 use torsion springs are contained in internal frame 2 bottom delivery ports.Because hyoplastron is contained on the internal frame delivery port by torsion spring, hyoplastron relies on the enclosed elastic delivery port usually, has prevented that mouse from entering by pipeline indoor; During draining, the gravity of water makes the hyoplastron beveled, does not affect draining.
