Further, described umbrella head includes that umbrella head and umbrella stem, umbrella head locking cap are provided with for interting what umbrella stem and medium flowed into perforate, and described umbrella stem is through umbrella head locking cap and extends in water swivel, and described umbrella head is fitted on the end face of umbrella head locking cap.
Further, equipped with filter screen at described water supply connector, prevent impurity in medium from flowing into cavity.
Further, one end of described Valve plug gets lodged in the water outlet of the pump housing, and the other end connects described stage clip, and stage clip is arranged in described water out adapter.
Further, equipped with relief valve on described water out adapter, when terminal container pressure is excessive, relief valve has effect and the explosion prevention function of pressure release.
Further, the output shaft of described motor has been rigidly connected cam, and motor is moved along a straight line by cam driven piston.
Further, described high pressure flow stable type pump also includes for installing motor, piston, the pump seat of the pump housing and pump cover.
The invention has the beneficial effects as follows:
(1) using umbrella head structure at water supply connector, piston can bottom out completely, and die cavity air can be emptied completely, and under back pressure, can not be affected by Installation posture, and flow performance is stable.
(2) using stage clip to add Valve plug structure at water out adapter, this structure can solve pump when not working, and at water inlet liquid level higher than the siphon problem of pump under water outlet liquid level, and the impact of this pressure reduction can realize eliminating by the pressure of regulation stage clip.
(3) filter structure at water supply connector can effectively prevent the impurity such as particulate matter from entering the pump housing, causes the inefficacy of pump, and can pass through choosing of filter screen mesh number, makes the pump housing can be suitably used for different environment.
(4) relief valve at water out adapter is possible to prevent the problem that terminal container pressure is excessive, can effectively realize pressure release and explosion-proof.
(5) comparing the tradition one-way valve structures such as duckbill valve, stable performance of the present invention, working life is higher, and cost advantage is obvious.

Detailed description of the invention
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Such as Fig. 1, shown in Fig. 2, a kind of high pressure flow stable type pump, it includes motor 2, piston 5, the pump housing 7, water supply connector 10 and water out adapter 15, described piston 5 stretches in the pump housing 7, and drive and make stretching motion by described motor 2 in the pump housing 7, the described pump housing 7 is provided with water inlet and outlet, described water supply connector 10 is arranged on water inlet, water out adapter 15 is arranged on water outlet, the umbrella head structure being made up of umbrella head 8 and umbrella head locking cap 9 it is provided with in the junction of water supply connector 10 and water inlet, it is provided with the stage clip being made up of stage clip 16 and Valve plug 6 in the junction of water out adapter 15 and outlet and adds Valve plug structure.
As shown in Figure 1, Figure 3, described umbrella head 8 includes umbrella head and umbrella stem, umbrella head locking cap 9 is provided with for interting what umbrella stem and medium flowed into perforate, and described umbrella stem is through umbrella head locking cap 9 and extends in water swivel 10, and described umbrella head 8 is fitted on the end face of umbrella head locking cap 9.Wherein, equipped with filter screen 11 at described water supply connector 10, prevent impurity in medium from flowing into cavity.
As Figure 1 and Figure 4, one end of described Valve plug 17 gets lodged in the water outlet of the pump housing 7, and the other end connects described stage clip 16, and stage clip 16 is arranged in described water out adapter 15.Wherein, equipped with relief valve 14 on described water out adapter 15, when terminal container pressure is excessive, relief valve has effect and the explosion prevention function of pressure release.
As shown in Fig. 2, Fig. 5, the output shaft of described motor 2 has been rigidly connected cam 3, and motor 2 drives piston 5 to move along a straight line by cam 3.Wherein, described high pressure flow stable type pump also includes for installing motor 2, piston 5, the pump seat 4 of the pump housing 7 and pump cover 13.
The operation principle of the present invention is: using synchronous motor or direct current generator as the source of driving, Inlet and outlet water (gas) place is respectively provided with check valve (identical structure or different structure), and cam 3 is rigidly connected with motor 2 output shaft.Umbrella head structure adopted by water supply connector check valve, and water out adapter check valve uses stage clip and Valve plug structure.
Cam 3 drives piston 5 to move along a straight line, and when piston 5 retreats in the pump housing 7 die cavity, at water supply connector, umbrella head 8 is opened, and medium tapping from umbrella head locking cap 9 flows into the pump housing 7 die cavity, (now at water out adapter at check valve in off position).This is the extraction process of medium.
When piston 5 travels forward in the pump housing 7 die cavity, umbrella head 8 is fitted with umbrella head locking cap 9 under the effect of pressure medium, medium is stoped to flow out at water supply connector 10, under the effect of pressure medium, check valve at water out adapter 15 is forced to open, medium flows out at water out adapter 15, and this is the discharge process of medium.
Equipped with filter screen 11 at water supply connector 10, preventing impurity in medium from flowing into cavity, cause the inefficacy of check valve, equipped with relief valve 14 at water out adapter 15, when terminal container pressure is excessive, relief valve has the effect of pressure release, has explosion prevention function.
