Abstract
The utility model discloses a split type valve core which solves the problem that a valve body cap of the prior integrated type valve core rotates along with a rotary stem, and comprises a valve body of a tap; an upper opening of the valve body is connected with a valve body cap inside which a rotary stem is arranged; a control end of the rotary stem is arranged outside the valve body cap, a lower end of the rotary stem is provided with a movable valve plate; an inner cavity of the valve body is provided with a stop valve plate which is matched with the movable valve plate correspondingly; limit steps which limit rotation angles of the rotary stem are arranged on the wall of the inner cavity of the valve body; when the rotary stem is rotated to the limit position, the valve body cap is not driven to rotate, thereby avoiding the danger of the valve core breaking away from the valve body due to misoperation, and making use safer and more reliable.
Description
Technical field
The utility model relates to a kind of spool, particularly a kind of split type spool.
Background technique
Traditional spool is the integral type stand-alone assembly, it includes core body, rotary valve rod is installed in the core body, the core body inner chamber is provided with the angle of swing of limited step restriction rotary valve rod, moving valve plate is equipped with in the rotary valve rod lower end, the core body bottom is provided with only valve block, and moving valve plate ends valve block relatively and rotates the folding of controlling spool.This spool is generally with on the valve body that is threaded in angle valve or water tap, and because body cap spacing to rotary valve rod, if the excessive body cap that will make of the dynamics that the user rotates also rotates in the lump, cause the loosening of connecting thread, spool has the danger that breaks away from valve body.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of split type spool, and limited step is located in the valve body, and body cap can not rotate with rotary valve rod, and is safe and reliable.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of split type spool, the valve body that comprises all water taps, the upper opening of valve body is connected with body cap, rotary valve rod is installed in the body cap, the control end of rotary valve rod places outside the body cap, the lower end of described rotary valve rod is equipped with moving valve plate, and body cavity is equipped with the valve block that ends with described moving valve plate corresponding matching, also is provided with the limited step of restriction rotary valve rod angle of swing on the body cavity wall.
As improvement of the technical scheme, described body cavity is provided with chute, ends valve block and is provided with the chimb that cooperates with described chute.
As further improvement in the technical proposal, the lower end of described rotary valve rod is provided with the boss that can contact with limited step; Described moving valve plate is inlaid in the bottom of boss by counterbore.
The beneficial effects of the utility model are: because spool adopts split-type structural, rotary valve rod and moving valve plate be arranged in the body cap and end valve block and limited step is arranged in the valve body, can not drive body cap when the rotation rotary valve rod arrives spacing position rotates, avoid because operate miss or long-term the use cause the danger of spool from the valve body disengaging, safe and reliable.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a perspective view of the present utility model;
Fig. 2 is a structure explosive view of the present utility model;
Fig. 3 is the perspective view of valve body;
Fig. 4 is Fig. 3 A bilge construction enlarged view;
Fig. 5 is the sectional structure schematic representation of valve body.
Embodiment
Referring to figs. 1 through Fig. 5, a kind of split type spool of the present utility model, the valve body 1 that comprises all water taps, the upper opening 11 of valve body 1 is by the body cap 2 that has been threaded, rotary valve rod 3 is installed in the body cap 2, and the control end 31 of rotary valve rod 3 places outside the body cap 2, and the lower end of rotary valve rod 3 is equipped with moving valve plate 4, valve body 1 inner chamber is equipped with the only valve block 5 with described moving valve plate 4 corresponding matching, also is provided with the limited step 12 of restriction rotary valve rod 3 angle of swing on valve body 1 internal chamber wall.When angle valve or water tap are in closed condition, moving valve plate 4 with end valve block 5 and cooperate and seal through hole 52 on the valve block 5 only, current can not pass through only valve block 5.When needs are opened spool, rotate the control end 31 of rotary valve rod 3, rotary valve rod 3 drives moving valve plate 4 and rotates, limited step 12 stopped when rotary valve rod 3 turned to maximum angle, at this time through hole 52 is open-minded fully, and current flow out from water outlet 15 with the through hole 52 that ends valve block by the water intake 14 of valve body 1 successively.Because spool adopts split-type structural, rotary valve rod 3 and moving valve plate 4 be arranged in the body cap 2 and end valve block 5 and limited step 12 is arranged in the valve body 1, can not drive body cap 2 when rotating the spacing position of rotary valve rod 3 arrival rotates, avoid because operate miss or long-term the use cause the danger of spool from the valve body disengaging, safe and reliable.
With reference to Fig. 2 to Fig. 5, in the present embodiment, valve body 1 inner chamber is provided with chute 13, ends valve block 5 and is provided with the chimb 51 that cooperates with described chute 13.By cooperating of chimb 51 and chute 13, will end valve block 5 and be fixed in valve body 1 inner chamber, simplified mounting structure.
In addition, the lower end of rotary valve rod 3 is provided with the boss 32 that can contact with limited step 12, and moving valve plate 4 is inlaid in the bottom of boss 32 by counterbore 41.By this structure, rotary valve rod 3 turns to maximum angle when boss 32 contacts with limited step 12, and moving valve plate 4 also turns to and avoids the only position of the through hole 52 of valve block fully simultaneously, makes through hole 52 open-minded fully, simple and reliable for structure.
