Embodiment 1

[0040] Such as Figures 1 to 4 As shown, this embodiment provides a valve-type maintenance-free one-way valve, including a valve body front cover 3 and a valve body shell 4 connected together, the valve body front cover 3 includes a valve inlet pipe 3.1, and one end of the valve inlet pipe 3.1 Extending into the valve body shell 4, the port of the valve inlet pipe 3.1 extending into the valve body shell 4 is set as a beveled port, and the valve body shell 4 is provided with a valve sheet 5 for blocking the beveled port, and one end of the valve sheet 5 is fixed At the top of the valve inlet pipe 3.1.

[0041] In this embodiment, when the fluid passes through the valve-type maintenance-free one-way valve, it first passes through the front cover of the valve body, and under the impact of the fluid, the valve plate blocked at the port of the oblique section is opened, and the fluid enters the inside of the valve body shell and is discharged. , when no fluid passes through, the v...

Embodiment 2

[0043] Such as Figures 1 to 4 As shown, this embodiment is further optimized on the basis of Embodiment 1. Specifically, one end of the valve inlet pipe 3.1 is provided with a water inlet port 3.2, and the outer wall of the valve inlet pipe 3.1 is provided with a ring for sealing the valve body shell 4 The cover 3.3 of the port, the water inlet port 3.2, the valve water inlet pipe 3.1 and the cover 3.3 are integrated structures, and the valve body shell 4 includes the front section 4.1 of the casing, the middle section 4.2 of the casing and the rear section of the casing which are sequentially connected into one 4.3, the front section 4.1 of the shell is connected with the cover 3.3, the interception area of ​​the middle section 4.2 of the shell gradually decreases along the direction of water flow, the end of the rear section 4.3 of the shell is connected with the water outlet interface 6, and the outer wall of the valve body shell 4 is provided with a water flow direction I...

Embodiment 3

[0047] Such as figure 1 As shown, this embodiment is further optimized on the basis of embodiment 1, specifically, the slope of the port on the beveled plane is θ, θ=120°-140°.

[0048] In this embodiment, the inclination range of the oblique section port is 120°-140°, which can make the valve sheet smoothly seal the oblique section port under the action of its own weight, and the sealing effect is good. There will be gaps between the ports, which cannot be completely blocked. If the slope is too large, the contact area between the valve and the valve will be larger when the fluid impacts the valve. If the impact force is not enough, the valve will not open completely, and the fluid will not pass smoothly. The range not only ensures the sealing effect, but also ensures the smooth drainage, and the design size and structure are scientific and reasonable.

Abstract

The invention discloses a valve-type maintenance-free non-return valve, and a house draining system, and belongs to the technical field of building draining. The valve-type maintenance-free non-returnvalve comprises a valve body front cover and a valve body housing which are connected together; the valve body front cover comprises a valve water inlet pipe; one end of the valve water inlet pipe isdesigned to stretch into the valve body housing; the end of the valve water inlet pipe stretching into the valve body housing is designed to be a diagonal plane end; a valve sheet used for blocking the diagonal plane end is arranged in the valve body housing; one end of the valve sheet is fixedly arranged on the top of the valve water inlet pipe. The valve-type maintenance-free non-return valve is capable of blocking stink smell, and at the same time, pipeline blocking is not caused, maintenance is avoided, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of building drainage, in particular to a valve-type maintenance-free one-way valve and a house drainage system. Background technique [0002] The discharge of house toilet and kitchen sewage is an unavoidable problem in family living buildings or office buildings. The basic requirements for the house drainage system are: (1) smooth drainage; (2) to prevent the odor of the sewer from invading the room along the pipeline in reverse ; (3) Pipeline blockage does not occur during long-term use. Such as Figure 7 As shown, the current common method to solve the first two requirements is to connect a U-shaped pipe member 1 in series in the drainage system. The odor in the pipe cannot reversely invade the room along the pipeline, but there is currently no better active solution to the third anti-silting requirement. We can only passively open an inspection and dredging port 2 at the bottom of the U-shaped pipe memb...
