Formula is connected on mounting portion and the internal circle for being equipped with the connector for being vented imbibition channel and be successively set in exhaust imbibition channel
Ball and spring.Through the setting of mounting portion and function part, in this way when function part breaks down, it may be convenient to replacement is removed,
Cost is relatively low, and realizes exhaust liquid suction function by ball and spring, this spline structure is simple, and effect is preferable.
Preferably, being equipped with the first sealing ring between the mounting portion and function part.It is set between mounting portion and function part
The first sealing ring is set, the two sealing effect in this way is preferable.
Preferably, setting in the exhaust imbibition channel, there are two steps to be divided into three parts for imbibition channel is vented, respectively
First part, second part and Part III, two steps are respectively first step and second step, the spring one end with
First step offsets, and the spring other end offsets with ball one end, and the second step is equipped with for sealing ball and second
Second sealing ring of rank.Two steps are set, and one is used for fixed spring, and one is used to fix the second sealing ring, this spline structure
What is be arranged is simple, and exhaust imbibition effect is preferable.
Preferably, the diameter of ball is less than the diameter in first part channel and is greater than the diameter in second part channel.This
Sample ball can only be mobile in first part or resists through-hole or resist the second sealing ring, can play well exhaust and
Imbibition effect.
Preferably, the difference of the diameter of the diameter and first part channel of the ball is 0.4-0.5mm.In this way,
Gap is moderate between ball and the first part's inner wall for being vented imbibition channel, can supplied gas discharge well, can not allow water
It is flowed out between the two.
Preferably, being additionally provided with the clamping portion for fixing pipette on the connector.Setting can be fixed preferably in this way
Pipette.

Specific embodiment
The utility model is described further below in conjunction with attached drawing and specific embodiment, but the utility model is not only
It is limited to following specific embodiments.
As shown in Figure 1, a kind of plunger pump, including the pump housing 1, the pump housing 1 is interior to be equipped with pipelined channel 3, and setting is inhaled in pipelined channel 3
Nozzle for liquid, the outer wall of imbibition nozzle are sealed by two sealing rings and 1 inner wall of the pump housing, imbibition nozzle include nozzle body 4 and
Nozzle passage 5 inside nozzle body is set, and diameter of the nozzle passage 5 close to 2 one end of water outlet is greater than far from water outlet 2 one
The diameter at end is equipped with a through-hole 7 on the pump housing inner wall between two sealing rings, and through-hole 7 is connected to nozzle passage 5, through-hole 7
Wall is equipped with a mounting portion 6, and a connector 9 is then threadedly coupled on mounting portion 6, and the is provided between connector 9 and mounting portion 6
One sealing ring 12, setting exhaust imbibition channel 8 inside connector 9, this exhaust imbibition channel 8 includes mainly three parts, is respectively
First part 13, second part 14 and Part III 15, diameter is successively reduced, and ball 10 is arranged in first part 13,
It can be moved in first part 13, being moved to can topmost contact with through-hole 7, and being moved to bottom can be with setting the
Second sealing ring 18 contacts on two steps 17, and one has been actually formed at second step 17 for accommodating the recessed of the second sealing ring 18
Slot, spring 11 are arranged in second part 14, and the setting of 11 lower end of spring offsets with first step 16,11 upper end of spring and ball 10
It offsets.
The working principle of the application exhaust is: air comes with pipelined channel, then supports ball from through hole and opens, but
Be because air pressure it is lower, ball will not be pressed onto and be resisted on the second sealing ring, thus air can along through-hole,
Then it is flowed through in the gap between ball and first part channel, can thus accelerate inner air discharge.
After inner air is drained, water can squeeze ball by through-hole, because hydraulic pressure is larger, water can be by ball at this time
Be pressed on the second sealing ring, at this time water cannot between ball and first part gap outflow because by the second sealing ring keep off
It firmly, so will not leak.
After this when user adjusts discharge pressure, when adjusting smaller to discharge pressure, through hole can generate venturi
Effect, i.e. through hole can generate suction, can will thus come in liquid adsorption from pipette, realize imbibition effect.
I.e. exhaust effect both may be implemented in the application, and imbibition effect also may be implemented, and vdiverse in function, structure is simple, installation
It is easy to maintain.
