Abstract
An emulsion pump capable of closing a one-way valve comprises a pressing head, a lock cover, a screw tooth, a main body, a main column, a piston, a glass ball, a pressure spring and a pipet, wherein the glass ball and a valve seat in the main body form a one-way valve, and the valve seat is communicated with the main body and the pipet. The emulsion pump is characterized in that a piston mounting position is arranged on the main column, an emulsion channel which leads the inner cavity of the main column and the inner cavity of the main body to be communicated is arranged on the piston mounting position, the piston and the piston mounting position are matched in a sliding way, one end of a pressure spring is matched with a spring seat in the main body, the other end is matched with a spring seat on the main column, the lower end of the main column can be matched with the valve seat, and the glass ball is fixed. With the structure and compared with the prior art, components of an auxiliary column are omitted, therefore, the emulsion pump has the characteristics of simple structure and convenient assembly, the lower end of the main column and the valve seat are matched to fix the glass ball under the state that the pressing head and the locking cover are locked, the glass ball can be prevented from leaving the valve seat, and emulsion enters the main body from the inside of the container.
Description
Technical field
The utility model relates to a kind of emulsion pump.
Background technology
Present prior art, a kind of emulsion pump of cutting out check valve comprises head, locking closure, thread, body, principal post, subpost, piston, glass bead, pressure spring and suction pipe, principal post is captiveed joint with subpost, and piston is installed in and is positioned on the piston installation position on the subpost; Principal post is threaded with head, and head and locking closure screw thread removably connect; Glass bead and intrinsic valve seat constitute check valve, and valve seat is communicated with body, suction pipe; Existing problems are: complex structure, and under the sealed state of head and locking closure, glass bead can break away from valve seat, causes emulsion to enter in the body, causes emulsion to flow out from head.
Summary of the invention
The purpose of this utility model is: a kind of emulsion pump of cutting out check valve is provided, and it is not only simple in structure, and is easy to assembly, and in head and locking closure locked state, with the stationkeeping of glass bead, can prevent that emulsion from flowing out.
The utility model is achieved in that a kind of emulsion pump of cutting out check valve comprises head, locking closure, thread, body, principal post, piston, glass bead, pressure spring and suction pipe, glass bead and intrinsic valve seat constitute check valve, valve seat is communicated with body, suction pipe, its special character is: a piston installation position is arranged on the described principal post, the milk channel that the principal post inner chamber is communicated with chamber body is arranged on the piston installation position; Piston and piston installation position bearing fit;
Described pressure spring one end cooperates with body inner spring seat, the other end cooperates with spring perch on the principal post;
Described principal post lower end can cooperate with valve seat, and glass bead is fixed.
Described a kind of emulsion pump of cutting out check valve, its special character is: the ball curved is in the lower surface of principal post.
Described a kind of emulsion pump of cutting out check valve, its special character is: the pole that distributes is ringwise arranged, the lower end of described pole curved spherical in shape on the lower surface of principal post.
A kind of emulsion pump of cutting out check valve of the utility model owing to adopt such structure, compared with prior art, saves the subpost parts, thereby has characteristics simple in structure, easy to assembly; Under the sealed state of head and locking closure, the lower end of principal post cooperates the stationkeeping with glass bead with valve seat, can prevent to lift off a seat because of glass bead, and emulsion is by entering body in the container.
Description of drawings
Fig. 1 is the utility model cutaway view.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, a kind of emulsion pump of cutting out check valve comprises head 1, locking closure 2, thread 3, body 4, principal post 5, piston 6, glass bead 7, pressure spring 8 and suction pipe 9, and principal post 5 is captiveed joint with head 1 screw thread, and head 1 removably connects with locking closure 2 screw threads; Valve seat 41 in glass bead 7 and the body 4 constitutes check valves, and valve seat 41 is communicated with body 4, suction pipe 9; One piston installation position 51 is arranged on the described principal post 5, the milk channel 52 that principal post 5 inner chambers are communicated with body 4 inner chambers is arranged on the piston installation position 51; Piston 5 and piston installation position 51 bearing fits;
Described pressure spring 8 one ends cooperate with body 4 inner spring seats, the other end cooperates with spring perch on the principal post 5;
Under head 1 and locking closure 2 locked state, described principal post 5 lower ends can cooperate with valve seat 41, and glass bead 7 is fixing.
For the lower end of realizing principal post 5 better cooperates with glass bead, the lower surface of principal post 5 is the ball curved.
As further improvement: the pole 53 that distributes is ringwise arranged, the lower end of described pole 53 curved spherical in shape on the lower surface of principal post 5.
As shown in Figure 1, joint 1 is locked together in locking closure 2, at this moment, the lower end of principal post 5 cooperates with valve seat 41 glass bead 7 is fixed on the valve seat 41, like this when newly being assembled to this practicality on the emulsion container, or the emulsion container can prevent that emulsion from entering in the body through valve seat 41 in transportation, flows out through principal post, head again.
Under Fig. 1 state, head 1 is separated with locking closure 2, under the effect of pressure spring 8, principal post 5 from bottom to top moves, and principal post 5 stretches into locking closure 2, at this moment, can upper and lowerly push head, sprays emulsion from head 1, when quitting work, can head 1 and locking closure 2 is sealed.
