Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.
As shown in Figure 1 to Figure 3, the stopcock of a kind of belt supporting frame of the present utility model, comprise the valve body 1 with cavity 11, the cock body 2 with shank 21 and piston part 22 and the valve gap 3 piston part 22 is accommodated in cavity 11, the first passage 121 and second channel 122 that are communicated with cavity 11 is also provided with in valve body 1, first passage 121, the internal surface of second channel 122 is provided with somely spaced apart leads glue groove 12a, lead glue groove 12a all to extend from cavity 11 side toward valve body 1 outer wall, cavity 11, the surface of first passage 121 and second channel 122 is one-body molded valve body liner 1a, valve body liner 1a covers and leads glue groove 12a.When injection molding valve body liner 1a, the inner lining material of melting will flow valve body 1 with the gap of mould, owing to leading the existence of glue groove 12a, it is relatively little that melted material flows through resistance, therefore melted material can occupy the space of leading glue groove 12a fast, then to lead toward both sides diffusion centered by glue groove 12a, adjacent two melted material contact merging led glue groove 12a and extrude, occupy adjacent gap of leading between glue groove 12a then completely.So first valve body liner 1a shaping in not easily leave bubble, the sealing of valve and corrosion resistance can ensure, second valve body liner 1a and valve body 1 are with groove combination of shape and state, and intensity is better.
As shown in Figure 2 and Figure 3, valve body 1 is respectively provided with a flange 13 at first passage 121 and second channel 122 outer vent position, two flange 13 are provided with a pair scaffold 14 towards valve gap 3 direction, each scaffold 14 offer not through the mounting hole 141 of flange 13.Can be directly fixed on mounting hole 141 place of scaffold 14 when being also provided with the auxiliary actuator of control cock body 2 above stopcock, the fixing of auxiliary actuator does not affect valve gap 3 position, does not take valve gap 3 space; Because mounting hole 141 is not through flange 13, therefore it does not affect the agent structure of flange 13 yet, and location is convenient and firm; Two mounting holes 141 form two immovable points across pilled cock axis both sides, in assembling, the alignment of auxiliary actuator and cock body 2 is debugged and is changed auxiliary actuator into and valve body 1 is debugged at the relative position of fixed point, adjustment accuracy is higher, and therefore the structure of scaffold 14 is more reasonable.
As Figure 1 and Figure 4, piston part 22 comprises the top 221 be connected with shank 21, the first side joint 2221 extended from both sides, top 221 and the second side joint 2222 and connects the bottom 223 of the first side joint 2221 and the second side joint 2222 simultaneously, top 221, first side joint 2221, second side joint 2222 and bottom 223 surround the liquid pass hole 224 that penetrates piston part 22, surface, piston part 22 is covered with cock outer lining 2a, and valve body liner 1a internal surface and cock outer lining 2a outer surface are sealed and matched.When cock 2 rotate to liquid pass hole 224 be communicated with first passage 121 and second channel 122 simultaneously time, valve open, liquid freely can pass through valve, and the rotation angle of cock body 2 affects the flow of liquid by valve.Cock outer lining 2a can play the effect of isolated fluid and cock body 2, arrives the effect preventing cock body 2 from corroding.Because valve body liner 1a and cock outer lining 2a all can be obtained by injection moulding, both surface of contact are smooth, and sealing effect is excellent and stable.
As Figure 1 and Figure 4, the internal surface that valve body liner 1a is arranged in cavity 11 is little first conical surface (mark) of outer imperial palace, second conical surface (mark) that the outer surface of cock outer lining 2a matches in, structure identical with the first conical degree of conical surface, as long as apply less pressure at valve gap 3 position to cock body 2, the sealing between first conical surface and second conical surface can be guaranteed, simultaneously less on the impact of valve regulated resistance.
As Figure 1 and Figure 4, piston part 22 is provided with the injecting hole 225 of some through liquid pass holes 224 and piston part 22 outer wall, and cock outer lining 2a occupies space in whole injecting hole 225.If do not have injecting hole 225, the cock outer lining 2a be coated on outside piston part 22 is shell-like structure, and intensity is low, and the rear cock outer lining 2a of permanent use is easy to crack so that lost efficacy to the protective action of cock body 2; Due to the existence of injecting hole 225, shaping cock outer lining 2a is network-like, forms more stable entirety with cock body 2, reduces cock outer lining 2a cracking risk, improves working life.
Above-described is only mode of executions more of the present utility model.For the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
