Abstract
The utility model discloses a gas low pressure valve, characterized by turn round board (5) and turn round card (6) and for the convex-concave structure cooperation, with turn round and connect one on turning handle (9) that card (6) link to each other and curve groove (10), connecting rod (11) and bent hub connection, turning handle (9) through screw (8) with turn round the card and be connected.
Description
Technical field
The utility model relates to a kind of pipeline gas low pressure valve.
Background technique
Chinese patent announces in the technology of relevant combustion gas low pressure valve that the opening device that a kind of low pressure valve is arranged is by the mutual motion of two magnetic patch the shifting block that is engaged on the screw rod to be moved, thereby the lifting valve gap makes gas circuit open or compress valve gap gas circuit is closed.This structure can make low pressure valve have start-stop performance preferably, and the pressure loss is little, and is safe and reliable.But the matching design of shifting block and screw rod is also not satisfactory, the structure more complicated, and difficulty of processing is bigger, and cost is higher.
The content of model utility
The technical problems to be solved in the utility model provides the start-stop device of a kind of manufacturing simple in structure, easy, lower-cost low pressure valve.
Technological improvement of the present utility model is: turning round plate and turning round card is the convex-concave structure cooperation, is connected a bent axle on the turning handle continuous with turning round card, and connecting rod is connected with bent axle.
Further technological improvement of the present utility model is: turning handle is by screw and turn round card connection.
Good effect of the present utility model is: since adopt with turn round plate concavo-convex cooperate turn round moving turning handle of cassette tape and bent axle rotation, act on gland thereby order about connecting rod, make gland to the unlatching of valve port or close more flexible.It has simple in structure, easy manufacturing, start-stop performance is good, cost is low advantage, is suitable for using in the gas pipeline low pressure valve.
Description of drawings
Fig. 1: structural representation of the present utility model.
The A-A sectional view of Fig. 2: Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2, valve body 7 outer sides are provided with a motor 1, connect a magnetic patch 2 on the axis of motor 1, are closed in the case 4 with magnetic patch 2 corresponding magnetic patch 3.This magnetic patch 3 directly or indirectly with turn round plate 5 and be connected, turning round card 6 is concavo-convex the cooperation with turning round plate 5.Turning handle 9 by screw 8 with turn round card 6 and join, on turning handle 9, also be connected with a bent axle 10.The lower end of bent axle 10 is positioned at the chute 12 of gland 11, and the intrinsic capping 17 in gland 11 bottoms leaves pressure relief opening 14 on the valve plate 13.
When motor 1 operation, two magnetic patch 2,3 also rotate in the same way by the attraction force in magnetic field, and magnetic patch 3 drives to be turned round plate 5 and drive and turn round card 6 and also rotate simultaneously, thereby can be by being center of circle rotation with turning handle 9 and bent axle 11 with screw 8 with turning round the screw 8 that card 6 links to each other.Because the lower end of connecting rod 10 is positioned at the chute 12 of gland 11, when connecting rod 10 can drive gland 11 upwards the time and capping 17 is upwards lifted, combustion gas is discharged a part from pressure relief opening 14 earlier.Along with the continuation of gland 11 upwards, whole valve plate 13 also breaks away from valve port 16 by the rotation of valve plate seat 15 thereupon, makes a large amount of combustion gas discharge smoothly.When motor 1 inverted running, magnetic patch 2,3 and turn round plate 5, turn round card 6, turning handle 9 and bent axle 10, connecting rod 11 equal reversing motions, by connecting rod 11 lower ends gland 11 is depressed, make pressure relief opening 14 and valve port 16 sealings, thereby stop air feed.
Claims (2)
1, a kind of combustion gas low pressure valve comprises corresponding magnetic patch (2), (3), it is characterized in that turning round plate (5) and turn round card (6) cooperating for convex-concave structure, is connected a bent axle (10) on the turning handle (9) continuous with turning round card (6), and connecting rod (11) is connected with bent axle (10).
2, combustion gas low pressure valve as claimed in claim 1, it is characterized in that turning handle (9) by screw (8) with turn round card (6) and be connected.
