Abstract
The utility model discloses a teflon valve clack assembling device. The assembling device comprises a connection rod and a force transmission drum; one end of the connection rod is fixedly connected with the upper end of the force transmission drum; the force transmission drum is shaped like a hollow drum; two sections of symmetric concave arcs are arranged at the lower end surface of the force transmission drum; the shapes of the two sections of concave arcs are matched with the shape of a bulge in the middle of the surface of a valve clack; the arc surfaces of the two sections of symmetric concave arcs are fully contacted with the bulge in the middle of the surface of the valve clack; the connection rod is fixed on a power mechanism. Compared with the prior art, the teflon valve clack assembling device has the beneficial effects that the existing machining procedure and machining mode do not need to be changed, operators do not need extra training, and the production cost does not need to be increased; the stress areas of the assembling device and the valve clack are increased, and the resistance performance of the valve clack is effectively increased; the structure is simple, the manufacturing is convenient and popularization and application are favorably performed in the industry.
Description
Technical field
The utility model belongs to centre-pivoted butterfly valve processing technique field, relates in particular to a kind of polytetrafluoroethylene (PTFE) flap assembling device.
Background technology
Centre-pivoted butterfly valve is a kind of parts that are used for realizing pipe-line system break-make and flow-control, in many fields such as oil, chemical industry, metallurgy, water power, obtains applying very widely.The architectural feature of centre-pivoted butterfly valve is that rotating shaft core, butterfly plate center, body center are on same position.
Flap is a vitals of centre-pivoted butterfly valve always, and traditional flap is metal manufacture, and the installation of metal flap often adopts the mounting means utilizing in metallic rod jacking valve seat.Along with the development of centre-pivoted butterfly valve industry, for the flap that adapts to various application scenarios has also been produced out, comprising the flap that utilizes polytetrafluoroethylene (PTFE) to make, but, because the particularity of polytetrafluoroethylene (PTFE) flap material adopts traditional flap mounting means, may cause cut to flap surface, destroy even completely, and then cause the wasting of resources and cost to increase.
How quick the flap of polytetrafluoroethylene (PTFE) manufacture, safety are assembled on valve seat is the technical barrier of expecting solution in centre-pivoted butterfly valve industry always.
Summary of the invention
The purpose of this utility model is to provide a kind of polytetrafluoroethylene (PTFE) flap assembling device, with solve in prior art, exist can not the flap of polytetrafluoroethylene (PTFE) manufacture is quick, safety be assembled to the problem on valve seat.
For realizing the purpose of this utility model, the utility model provides a kind of polytetrafluoroethylene (PTFE) flap assembling device, described assembling device comprises connecting rod and power transmission cylinder, described connecting rod one end is fixedly connected with described power transmission cylinder upper end, it is hollow barrel-type that described power is transmitted cylinder, its lower surface is with two sections of symmetrical concave arcs, the shape of described two sections of symmetrical concave arcs matches with the boss shapes at middle part, described flap surface, and the cambered surface of described two sections of symmetrical concave arcs contacts completely with the lug boss at middle part, described flap surface; Described connecting rod is fixed on actuating unit.
Wherein, described actuating unit is hydraulic cylinder or pneumatic cylinder.
The beneficial effects of the utility model are, compared with the prior art, without changing existing manufacturing procedure and processing mode, to operating personnel without additionally training, without increasing production cost; Increase the lifting surface area of assembling device and flap, effectively improved the drag performance of flap; Simple in structure, easy to make, be conducive to industrially apply.
Brief description of the drawings
Fig. 1 is structural representation a of the present utility model;
Fig. 2 is structural representation b of the present utility model;
Fig. 3 is structural representation c of the present utility model;
In figure, 1-connecting rod, 2-power is transmitted cylinder.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and beneficial effect clearer, below in conjunction with embodiment, the utility model is further elaborated.Should be understood to specific embodiment described herein only in order to explain the utility model, be not limited to protection domain of the present utility model.
Fig. 1, Fig. 2, Fig. 3 are respectively and observe from different perspectives structural representation of the present utility model.
As shown in Figure 1, Figure 2, Figure 3 shows, the utility model provides a kind of polytetrafluoroethylene (PTFE) flap assembling device, with solve in prior art, exist can not the flap of polytetrafluoroethylene (PTFE) manufacture is quick, safety be assembled to the problem on valve seat.
The utility model provides a kind of polytetrafluoroethylene (PTFE) flap assembling device, described assembling device comprises connecting rod and power transmission cylinder, described connecting rod one end is fixedly connected with described power transmission cylinder upper end, it is hollow barrel-type that described power is transmitted cylinder, its lower surface is with two sections of symmetrical concave arcs, the shape of described two sections of symmetrical concave arcs matches with the boss shapes at middle part, described flap surface, and the cambered surface of described two sections of symmetrical concave arcs contacts completely with the lug boss at middle part, described flap surface; Described connecting rod is fixed on actuating unit.
Wherein, described actuating unit is hydraulic cylinder or pneumatic cylinder.
When use, described connecting rod is fixed on actuating unit, also can utilizes artificial strike that power is provided, the cambered surface of two sections of symmetrical concave arcs contacts with the bossing face at middle part, flap surface completely, increase lifting surface area, then, provide power that described flap is squeezed in valve seat, the inside at middle part, flap surface is rotating shaft, this location comparison is firm, utilize this position, can be stressed even, more ensure the security of processing.
The beneficial effects of the utility model are, compared with the prior art, without changing existing manufacturing procedure and processing mode, to operating personnel without additionally training, without increasing production cost; Increase the lifting surface area of assembling device and flap, effectively improved the drag performance of flap; Simple in structure, easy to make, be conducive to industrially apply.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
