Abstract
The utility model discloses a safety valve pull handle top plate which comprises a top plate body. A mounting hole is formed in the top plate body, a positioning connection portion is formed by stretching in the axial direction of the top plate body and is connected with a safety valve handle, the mounting hole penetrates through the top plate body and the positioning connection portion, at least two parallel connection faces are symmetrically arranged on the positioning connection portion in the vertical face direction, and each parallel connection face is wrapped with an anti-sliding elasticity layer. Due to the fact that each parallel connection face is wrapped with the anti-sliding elasticity layer, the connection stability of the handle and the positioning connection is improved greatly, sliding is avoided. Compared with a traditional processing technology, by means of the safety valve pull handle top plate, manpower and material resources are saved, the labor cost is reduced, and time and labor are saved.
Description
Technical field
The utility model relates to a kind of relief valve assembly, relates in particular to a kind of safety valve handle top board.
Background technique
Safety valve is a kind of safety protection valve; its open-shut device is subject under External Force Acting in normally off; when the pressure medium in equipment or pipeline raises, while exceeding specified value, automatically open, prevent that by discharge medium outside system in pipeline or equipment, pressure medium exceedes specified value.Safety valve belongs to self-acting valve class, is mainly used on boiler, pressurized container and pipeline, and pilot pressure is no more than specified value, and personal safety and equipment have been moved to important protective action.Safety valve structure mainly contains two large classes: handle type and Lever type.Handle type refers to that the sealing of flap and valve seat is by the active force of handle.Lever type is the active force by lever and weight.Existing handle type safety valve generally comprises the parts such as valve body, handle, top board and handle, traditional structure is generally to adopt top plate drilling, then the mode that adopts bearing pin to be connected with handle, this mode not only operation is loaded down with trivial details, trouble is installed, and has extended process time, reduce working efficiency, strengthened workman's labor intensity, adopted the mode of bearing pin link, working life is shorter.
Summary of the invention
The deficiency existing for prior art, technical problem to be solved in the utility model is, provide a kind of simple in structure, location is convenient, cost of production is low, working efficiency is high and effectively improve handle and the safety valve of the safety valve join strength top board of shaking hands.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of safety valve handle top board, comprise top board body, on top board body, offer mounting hole, it is characterized in that: extend to form a portion that is located by connecting that can be connected with described safety valve handle along the axial direction of described top board body, mounting hole runs through top board body and the portion that is located by connecting, in the described portion that is located by connecting, be at least provided with two symmetrical parallel junction surfaces along vertical plane direction, on described parallel junction surface, be coated with antiskid elastic layer.
Above-mentioned safety valve handle top board, described parallel junction surface is symmetrical arranged four.
Above-mentioned safety valve handle top board, described in be located by connecting portion and the setting of this body by integral forming of top board.
The advantage of the utility model safety valve handle top board is: boring employing bearing pin and handle location on safety valve handle top board again, the directly orientation type with parallel junction surface clamping with handle, make adjustment, operation and easier for installation, on parallel junction surface, be coated with antiskid elastic layer, greatly improve the connective stability of handle and this portion that is located by connecting, avoided the generation of skidding, than having saved manpower and materials in original processing technology, reduce labour cost, time saving and energy saving.
Brief description of the drawings
Fig. 1 is whole-cutaway view of the present utility model;
Fig. 2 is that embodiment 1 the A of Fig. 1 is to structural representation.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further details;
As shown in Figure 1, 2, a kind of safety valve handle top board, comprise top board body 1, on top board body 1, offer mounting hole 2, extend to form a portion that is located by connecting 3 that can be connected with safety valve handle along the axial direction of top board body 1, in the portion of being located by connecting 3, be provided with four symmetrical parallel junction surfaces 4 along vertical plane direction, mounting hole 2 runs through top board body 1 and the portion 3 that is located by connecting, portion 3 and the one-body molded setting of top board body 1 are located by connecting, greatly improve working strength, on described parallel junction surface 4, be coated with antiskid elastic layer 5.
Certainly, above-mentioned explanation is not to restriction of the present utility model, and the utility model is also not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, variation, remodeling, interpolation or the replacement made, all should belong to protection domain of the present utility model.
Claims (3)
