Abstract
The utility model relates to a main body structure of a flue check valve switch, which belongs to the field of tools matched with kitchen fume exhaust systems and bathroom exhaust systems, and solves the problems that a baffle occupies the ventilation cross area of a flue after the baffle is opened, so that the exhaust resistance of the whole flue is large. The structure comprises a tubular valve main body, the baffle and a return spring, wherein one end of the valve main body is provided with an air inlet, and the other end of the valve main body is provided with an air outlet; the baffle is arranged at the air outlet of the valve main body, and the closed state of the baffle and the valve main body is an annular linear fully-sealed closed state; one end of the return spring is connected to the baffle, and the other end of the return spring is connected to the inner wall of the valve main body; and the baffle is hinged to one side of the valve main body at the air outlet and is laterally opened. The utility model has the characteristics that: the baffle does not occupy the ventilation cross area of the flue basically after being opened, the ventilation resistance of the system is small and the exhaust effect is good.
Description
Technical field:
The utility model relates to a kind of check valve for flue switch main body structure, belongs to the matching appliances field of kitchen exhaust system and toilet exhaust system.
Background technique:
Check valve for flue is the essential product that prevents the public flue return of smoke and smell of family, current, most check valve for flue products on the market, it all is the baffle plate opening ways up and down that utilizes gravity principle to provide to reply power, the shortcoming of this closed manners is to take the flue ventilation section after baffle plate is opened, and the whole exhaust resistance of flue is bigger.Substantially do not account for the flue ventilation section, the check valve product that system's exhaust resistance is little after needing a kind of baffle plate to open on the market.
The model utility content:
The purpose of this utility model provides a kind of check valve for flue switch main body structure, solves to take the flue ventilation section after the baffle plate that exists in the prior art is opened, the big problem of the whole exhaust resistance of flue.
The technical solution of the utility model is:
A kind of check valve for flue switch main body structure, this structure comprises valve body, baffle plate, Returnning spring, and valve body is a tubular, and the one end is an intake grill, and the other end is an exhaust outlet; Baffle plate is placed in the exhaust outlet place of valve body, and the closed state of baffle plate and valve body is the linear hermetically sealed closure of annular; One end of Returnning spring is connected on the baffle plate, and the other end of Returnning spring is connected on the inwall of valve body.
Described check valve for flue switch main body structure, baffle plate are articulated in exhaust outlet one side of valve body, and opening ways is that side direction is opened.
The beneficial effects of the utility model are:
1, the utility model is opened and closing structure by the side direction of baffle plate and valve body, removed the adverse effect of baffle plate gravity to system's air draft, baffle plate does not account for the flue ventilation section after opening substantially, be connected the power that baffle plate and valve body barrel upper reset spring provide baffle plate to reply closed state, reach the flexible and little effect of system's exhaust resistance of switch.
2, the utility model check valve for flue switch main body structure is installed in place, the public flue of dwelling house hole, it both can allow exhaust equipments such as the kitchen ventilator of premises or ventilating fan successfully indoor flue gas is discharged in the public flue, also can stop in the flue gas refluence inlet chamber in the public air exhaust channel.Thereby, solving existing check valve product by gravity unlatching baffle plate, the baffle plate after the unlatching takies the flue ventilation section, the problem that system's exhaust resistance is big.
3, adopt the utility model check valve for flue switch main body structure, can thoroughly solve the public flue of family fall cigarette, return flavor and advance problem such as mosquito.
Description of drawings:
Fig. 1 is the utility model structural representation;
Among the figure, 1 valve body; 2 baffle plates; 3 Returnning springs.
Embodiment:
As shown in Figure 1, the utility model check valve for flue switch main body structure mainly comprises valve body 1, baffle plate 2, Returnning spring 3 etc., and valve body 1 is cylindric, and the one end is an intake grill, and the other end is an exhaust outlet; Baffle plate 2 is placed in the exhaust outlet place of valve body 1, and baffle plate 2 is the linear hermetically sealed closure of annular with the closed state of valve body 1; One end of Returnning spring 3 is connected on the baffle plate 2, and the other end of Returnning spring 3 is connected on the inwall of valve body 1.
In the utility model, baffle plate 2 is articulated in exhaust outlet one side (left side or right side) of valve body 1, and opening ways is that side direction is opened.
In the utility model, the linear hermetically sealed closure of annular is meant that when closed, the surface of baffle plate 2 forms linear the contact with the loop configuration at cylindric valve body 1 exhaust outlet place, reaches hermetically sealed closure.
Working procedure of the present utility model is as follows:
The utility model check valve for flue switch main body structure is installed on place, flue hole, and during exhaust equipments such as unlatching kitchen ventilator or ventilating fan, the row of wind of exhaust equipments such as kitchen ventilator or ventilating fan provides power, and baffle plate 2 side direction are opened, and it is outdoor that flue gas is discharged to smoothly; When exhaust equipments such as kitchen ventilator or ventilating fan quit work, the spring-back force of Returnning spring 3 made baffle plate 2 returns on the exhaust outlet of valve body 1, is linear closed contact between the two.Like this, just reached the effect of reverse sealing, prevented that public flue from falling the effect of cigarette, taint of odour thereby play.The utlity model has and do not account for the flue ventilation section substantially after baffle plate is opened, the system ventilation resistance is little, the air draft good effectiveness.
Claims (2)
1. check valve for flue switch main body structure, it is characterized in that: this structure comprises valve body, baffle plate, Returnning spring, and valve body is a tubular, and the one end is an intake grill, and the other end is an exhaust outlet; Baffle plate is placed in the exhaust outlet place of valve body, and the closed state of baffle plate and valve body is the linear hermetically sealed closure of annular; One end of Returnning spring is connected on the baffle plate, and the other end of Returnning spring is connected on the inwall of valve body.
2. according to the described check valve for flue switch main body of claim 1 structure, it is characterized in that: baffle plate is articulated in exhaust outlet one side of valve body, and opening ways is that side direction is opened.
