Abstract
The improved spiral lifting cold water tap includes valve body, valve rod, valve clack, valve cover and handle, and features that the upper end of the valve cover is directly made into bowl-shaped sealing cover structure and the sealing ring is installed inside the sealing cover structure. Compared with the cold water tap of the prior art, the utility model discloses can save the regulation lid that a brass was made, avoid adopting the asbestos cord to pack, have further simplified structure, reduce the technology link, reduce cost, the leakproofness is good, has effectively avoided the pollution of asbestos cord stopping to quality of water simultaneously.
Description
The utility model relates to building hot-water heating device, particularly a kind of improved spiral lift cold water tap.
Present commercially available spiral lift cold water tap (being commonly called as water tap), it is made up of discrete component such as valve body, valve gap, valve rod, flap, Sealing (comprising seal washer and asbestos rope filler), the adjustable cap (also claiming sealing gland) that is contained in the valve gap upper end and handles.There is following shortcoming in it: required adjustable cap is the same with valve gap general by the brass material manufacturing, it is again the screw-internal thread fit by outside thread and valve gap upper end, because the needs in the sealing must be filled with the asbestos rope filler at the valve gap inner chamber of adjustable cap bottom, make that part is many, manufacturing process is complicated, installation is also complicated, and asbestos rope packing seal poor performance easily causes water pollution in addition, harmful to health, not wear-resistant again, make the adjustable cap position seepage often occur, be unfavorable for using water wisely.
The purpose of this utility model is a kind of improved spiral lift cold water tap of design, makes it to have the simplification process structure, the effect that the cost that reduces cost improves sealing and helps avoiding water pollution.
The utility model is to adopt following technological scheme to realize: it comprises valve body, valve rod, flap, valve gap, seal washer and handle composition, it is characterized in that directly making the sealing cover structure that is bowl type shape in the upper end portion of valve gap, the inner chamber that covers structure in sealing is equipped with circle sealing together.
The utility model is shaped on the sealing cover of disjunctor with it because of the upper end portion at valve gap, so needn't be at the upper end portion of valve gap machining internal thread, the adjustable cap (sealing gland) that needn't use the asbestos rope filler during assembling and cooperate with it, and need only be with an avirulent rubber seal (general " O " RunddichtringO that adopts), pack in the sealing cover of valve gap inner chamber upper end, refill the insertion valve rod and get final product, all the other assembly method steps are identical with prior art.
As from the foregoing, after adopting technique scheme, can replace the effect of former adjustable cap with the bowl type sealing cover of valve gap disjunctor, the valve gap upper end portion needn't machining internal thread, can make the processing diameter and highly reduce, the adjustable cap that whole cold water tap can save a brass material manufacturing again with avoid adopting the asbestos rope filler, can also improve sealability thereby have further simplified structure, reduce some mounting process link, the cost that reduces cost has effectively been avoided the pollution of asbestos rope stuffing to water quality simultaneously.
Below in conjunction with embodiment the utility model is described in further detail:
Fig. 1 is the integral installation distribution structure schematic representation of cold water tap;
Fig. 2 is the part schematic representation of valve gap.
Wherein: 1, valve body, 2, seal washer, 3, flap, 4, valve gap, 5, the bowl type sealing cover of valve gap upper end portion, 6, " O " RunddichtringO that cooperates with bowl type sealing cover, 7, valve rod, 8, handle.
With reference to accompanying drawing 1, the seal ring that cooperates with bowl type sealing cover 5 can adopt generally avirulent " O " type rubber seal 6.
Assembly process of the present utility model is as follows: can be filled into " O " RunddichtringO 6 earlier in the bowl type sealing cover 5 of valve gap 4 upper end portions, to install flap 3 and seal washer 2 and valve rod 7 covers packs in the valve gap 4, valve gap is tightened on the valve body 1 again, loads onto handle 8 at last and get final product.The utility model uses operating method and old-fashioned cold water tap identical (summary).
