Abstract
A cover valve type pipeline check device is characterized in that a circular pipe variable joint which is thin above and thick below is installed at the upper end of an inner pipe of an inverted groove double-layer pipe, a horizontal lip-shaped ring is protruded on one side of the lower portion of the inner wall of the inner pipe, and the lower end of the inner wall of the other side of the inner pipe extends inwards and horizontally and then extends downwards and vertically to form a platform. The upper surface of the platform is lower than the lower edge of the lip-shaped ring, and a plurality of inverted L-shaped columns which open towards opposite sides are protruded on the platform. A support plate is installed inside a cover valve, the edge of the unstayed front half portion of the cover valve abuts against the lower edge of the lip-shaped ring, and the unstayed front half portion of the cover valve can open downwards. Inverted L-shaped holes at the rear end of the cover valve are matched with the inverted L-shaped columns connected with the platform into a whole to fix the rear end of the cover valve, and the cover valve is in a closed state. By means of the cover valve type pipeline check device, backflow water, inverse smell and insect pests are all blocked in pipelines and cannot enter into the indoor, and therefore hygiene and cleanness of an indoor environment are ensured.
Description
Technical field
The utility model relates to the pipeline field, is a kind of pipeline anti-reversing clutch specifically.
Technical background
At present, the structure of the pipeline anti-reversing clutch of indoor use has trap formula, flip-shell etc.The anti-contrary structure of trap formula can only prevent that slight stink is converse, can not prevent against the current and insect pest; The anti-contrary structure of flip-shell causes poor sealing because seal is hard material, anti-contrary flavor weak effect.So the effect of anti-against the current, anti-contrary flavor of existing pipeline anti-reversing clutch and insect-pest is all undesirable.
The utility model content
The purpose of the utility model is, overcomes the defective of existing pipeline anti-reversing clutch, designs a kind of lid gate valve road anti-reversing clutch.The technical scheme of the utility model is: a kind of lid gate valve road anti-reversing clutch; Its special character is: in the interior pipe upper end of the bimetallic tube of falling the groove up-thin-low-thick pipe change is installed and connects; The protruding horizontal lip ring of inner tube wall bottom one side, the inside horizontal-extending in interior pipe opposite side inwall lower end extends to form a platform more downward vertically, and the upper surface of platform is lower than lip ring lower edge; Several openings of platform raising are towards " L " post of offside; In the lid valve gripper shoe is arranged, the loose first half of lid valve edge is lower than lip ring lower edge, and the loose first half of lid valve can be opened downwards; Lid valve rear end fall " L " hole and cooperates the rear end that will cover valve to fix with " L " post that falls that platform is connected as a single entity, cover valve and be in closed state.
During use; With the utility model with wash basin, wash the nappy gutter and be connected, when the weight of water in the device surpasses the support force of the lid valve that soft material makes, cover the loose first half of valve and open downwards; After sewage passed through, lid valve return under self elastic force effect was in closed state.When having in the pipeline against the current and during contrary flavor, have the lid valve of gripper shoe to contact with lip ring lower edge tightlier under converse power effect, close tighter.The utility model is removed pipe become and to connect, loading onto the grating frame that uses as floor drain and double-edged fine-toothed comb just becomes and cover the valve formula and prevent against floor drain.
Owing to adopt technique scheme, against the current, contrary flavor and converse insect pest all can not improve anti-against the current, anti-contrary flavor of pipeline and insect-pest effect through stoping converse lid valve, guaranteed that the health of indoor environment is clean.
Description of drawings
Fig. 1 is the structural front view of the utility model, and the accompanying drawing that makes an abstract;
Fig. 2 is the vertical view of the lid valve of the utility model.
Interior pipe in the drawings, 1, pipe becomes and to connect, 2, the bimetallic tube of falling the groove, 3, the lid valve falls " L " hole, 4, fall " L " post, 5, platform, 6, cover valve, 7, gripper shoe, 8, the lip ring, 9.
The specific embodiment
Below in conjunction with accompanying drawing and instance to originally further specifying.As shown in Figure 1; In interior pipe 9 upper ends of the bimetallic tube of falling the groove 2 up-thin-low-thick pipe change is installed and connects 1; In have the lid valve 6 loose first half edges of gripper shoe 7 to be lower than the lower edge of lip ring 8; Lid valve 6 rear ends fall " L " hole 3 and match the rear end of lid valve 6 is fixed on the platform 5 with " L " post 4 that falls that platform 5 is connected as a single entity, whole lid valve is in closed state.
With the utility model with wash basin, wash the nappy gutter and be connected after; When the weight that flows into water surpasses the support force of the lid valve 6 that soft material makes; Lid valve 6 loose first halfs are opened downwards, and after sewage passed through, lid valve 6 return under self elastic force effect was in closed state.When having sewage or foul smell converse in the pipeline, because the rear end of lid valve 6 is fixed on the platform 5, and lip ring 8 is on lid valve 6, and it is tighter that lid valve 6 loose first half edges contact with lip ring 8 lower edges under converse power effect, covers valve 6 and close tighter.Ducted retrograde insect pest can not be opened and covered valve 6 and pass through.The utility model removes the pipe change and connects 1, and loading onto the grating frame and the double-edged fine-toothed comb that use as floor drain just becomes from the anti-contrary floor drain of moving-cover type.
