As depicted in figs. 1 and 2, a kind of plunger pump of convenient disassembly, including the pump housing 1, the pump housing 1 are arranged with three in parallel and drawn water
Mechanism 2, each water pumping mechanism 2 include plunger 21 and plunger bushing 22, and plunger 21 is moved back and forth to complete to draw water in plunger bushing 22.
The water intaking valve 3 for unidirectional water inflow and the outlet valve 5 for unidirectional water outlet are provided with water pumping mechanism 2.
The space that the inwall of the top surface of plunger 21 and plunger bushing 22 is formed be chamber volume 4, equal on each outer wall of plunger bushing 22
The water inlet 41 and delivery port 42 communicated with chamber volume 4 is offered, water inlet 41 and delivery port 42 are vertically arranged, the He of water inlet 41
The internal diameter of delivery port 42 is identical.Internal thread segment 43 is provided with water inlet 41 and delivery port 42.
Water intaking valve 3 is identical with the structure of outlet valve 5.As shown in figure 3, water intaking valve 3 and outlet valve 5 include valve pocket 31
With three check valves 32 being rotatably arranged in valve pocket 31.Valve pocket 31 includes upper valve sleeve 311 and lower valve sleeve 312, the He of upper valve sleeve 311
Lower valve sleeve 312 symmetrically offers three mounting grooves 313, the raised line 314 for being provided at both ends with annular of mounting groove 313, upper valve sleeve 311
Fastened after being combined with lower valve sleeve 312 with bolt, three pairs of mounting grooves 313 form three cavities 315, and the both ends of cavity 315 are convex
The internal diameter of the position of bar 314 is less than the middle part internal diameter of cavity 315, and the arrangement mode of three cavities 315 and three water inlets 41 or
The arrangement mode of three delivery ports 42 is identical.
As shown in figure 4, check valve 32 includes valve casing 321, is arranged on two stubborn first 322 of 321 axial both ends of valve casing and hangs down
It is straight to be fixed on two external thread sections 323 for twisting first 322 end face.One end of the axial direction of check valve 32 is arrival end 33, and the other end is
Mouth end 34, the inner hollow of check valve 32 simultaneously penetrate with arrival end 33, the port of export 34.As shown in figure 3, the profile of valve casing 321 with
Cavity 315 is identical, and three check valves 32 are respectively arranged in three cavities 315 by valve casing 321, and both ends are supported with raised line 314
Connect, check valve 32 is rotated in cavity 315 and be not easy cavity 315.
Hemispheric block 3211 is provided with as shown in figure 4, being slided in the cavity of valve casing 321, the diameter of block 3211 is small
In the cavity inside diameter of valve casing 321, block 3211 is provided with spring 3212 close to the position of the port of export 34, and spring 3212 is by block
3211 are pressed on the valve casing 321 close to the direction of arrival end 33, and the runner in check valve 32 is enclosed while compression.

It is identical positive hexagonal column that two, which are twisted first 322, twists and is respectively arranged with packing ring 324 on first 322 end face.Two
External thread section 323 is symmetrical relative to check valve 32, and two external thread sections 323 can be threadedly coupled with internal thread segment 43.
During installation, as shown in Fig. 2 then three of water intaking valve 3 are located at by water intaking valve 3 respectively close to water inlet 41
The external thread section 323 at mouthful end 34 is close to the internal thread segment 43 of corresponding water inlet 41, then can use spanner turn respectively be located at into
The mouth side of end 33 twists first 322, then check valve 32 is rotated in cavity 315, and external thread section 323 is screwed into corresponding internal thread segment
In 43.It is then respectively that three of outlet valve 5 external thread sections 323 positioned at arrival end 33 are tight by outlet valve 5 close to delivery port 42
Be affixed on the internal thread segment 43 of delivery port 42, then can use spanner turn respectively positioned at the port of export 34 twist first 322, as described above it is complete
Into installation.Tighten rear packing ring 324 reliably to be compressed, play a part of strengthening sealing, valve pocket 31 is simultaneously by three check valves 32
Connect together, play and interlock locking effect.
Water intaking valve 3 is identical with the structure of outlet valve 5, and interchangeability is good, therefore produces a kind of water intaking valve 3 or outlet valve
5 can meet the needs of this plunger pump is for installation.When certain check valve 32 of water intaking valve 3 or outlet valve 5 breaks down, pass through
Twist first 322 and back out the water intaking valve 3 or outlet valve 5 of failure, and take valve pocket 31 apart, you can single maintenance is carried out to check valve 32 or is changed
Newly.
During work, plunger 21 moves toward the direction away from water inlet 41, then negative pressure is formed in chamber volume 4, due to check valve
Water in 32 can only one-way flow, then the check valve 32 positioned at the side of delivery port 42 close, the check valve 32 positioned at the side of water inlet 41
Open, so as to which water is sucked in chamber volume 4 from water inlet 41.Move, then hold toward close to the direction of water inlet 41 with back-plunger 21
Product forms malleation in room 4, then the check valve 32 positioned at the side of delivery port 42 is opened, and the check valve 32 positioned at the side of water inlet 41 is closed,
So as to by water from the discharge volume room 4 of delivery port 42.Constantly continuous pumpage is completed in circulation as described above, and three water pumping mechanisms 2 are simultaneously
Work, improves the efficiency drawn water.
Described above is only exemplary embodiment of the present utility model, not for limitation protection model of the present utility model
Enclose, the scope of protection of the utility model is determined by appended claim.
