To achieve these goals, technological scheme of the present invention is following:
A kind of three cylinder reciprocating pumps comprise pump case, are provided with in the pump case to be used to produce three piston cylinders of thrust and the cavity of three piston cylinder thrust direction one sides; It is characterized in that, be provided with into water vavle shelf in the said cavity, the water inlet vavle shelf is divided into water-inlet cavity and water chamber with cavity; Be provided with through hole in the said water inlet vavle shelf, be provided with check valve sheet in the through hole, the pump case of said water inlet vavle shelf side is provided with water intake; Said water intake connects the water inlet vavle shelf, and the pump case of said water chamber is provided with water outlet.
Above-mentioned a kind of three cylinder reciprocating pumps is characterized in that: be provided with in the said cavity and three corresponding three water inlet vavle shelves of piston cylinder.
Above-mentioned a kind of three cylinder reciprocating pumps is characterized in that: said three water inlet vavle shelves and on every side the slit between the housing be provided with the outlet valve pad, said outlet valve pad is connected on the water vavle shelf through spring.
Above-mentioned a kind of three cylinder reciprocating pumps, it is characterized in that: said piston cylinder comprises bent axle, connecting rod and plunger, and bent axle connects connecting rod, and connecting rod connects plunger through plunger pin, and stretch out outside the housing on the top of curved bar.
The beneficial effect that the present invention has: adopt the turnover water valve after the design of same cavity, and compare, valve simple installation, long service life, advantage such as load is light with pre-structure.
Description of drawings
Fig. 1 is a sectional view of the present invention.
Embodiment
For making structure characteristic of the present invention and the effect reached there are further understanding and understanding, cooperate detailed explanation, explain as follows in order to preferred embodiment and accompanying drawing:
Referring to Fig. 1; A kind of three cylinder reciprocating pumps; Comprise pump case 100; 120, three piston cylinders 110 of cavity that are provided with three piston cylinders 110 being used to produce thrust and three piston cylinder 110 thrust directions one sides in the pump case 100 are done back and forth movement and are produced thrust through promoting piston, and the liquid in the cavity 120 are released.
Be provided with into water vavle shelf 200 in the cavity 120; Water inlet vavle shelf 200 is divided into water-inlet cavity 121 and water chamber 122 with cavity 120, is provided with through hole in the water inlet vavle shelf 200, and an end of through hole is communicated with water intake 300; The other end of through hole is communicated with water-inlet cavity 121; Be provided with check valve sheet 210 in the through hole, the effect of check valve sheet 210 is to make liquid to flow into the water-inlet cavitys 121 and can not let liquid from water-inlet cavity 121, be back to water intake 300 from water intake 300, and the pump case 100 of water inlet vavle shelf 200 sides is provided with water intake 300; Water intake 300 connects water inlet vavle shelf 200, and the pump case 100 of water chamber 122 is provided with the water outlet (not shown).
In the time of work; When three piston cylinders 110 were inhaled backward, liquid entered into the through hole in the water vavle shelf into 200 from water intake 300, and then entered into water-inlet cavity 121 through check valve sheet 210; This moment, three piston cylinders 110 pushed away forward; Gap between the water vavle shelf 200 and pump case 100 flows in the water chamber 122 liquid along with thrust is passed into from water-inlet cavity 121, because check valve sheet 210 has been blocked the through hole of water inlet vavle shelf 200, makes liquid that can not be back to water intake 300 places simultaneously.
Be provided with in the cavity 120 and corresponding three the water inlet vavle shelves 200 of three piston cylinders 110, make flowing into the water-inlet cavitys 121 that liquid can be smooth more from water intake 300.
Three the water inlet vavle shelf 200 and on every side the slit between the housing 100 be provided with outlet valve pad 220; Outlet valve pad 220 is connected on the water vavle shelf 200 through spring 230; When piston cylinder 110 does not produce thrust; Outlet valve pad 220 is being blocked into water vavle shelf 200 and the slit between the housing 100 on every side under the effect of spring 230, make the outside seepage of liquid that can not, and when piston cylinder 110 produces thrusts; Liquid is pushed outlet valve pad 220 open next time in the effect of thrust, thereby enters into water chamber 122.
Piston cylinder 110 comprises bent axle 111, connecting rod 112 and plunger 113; Bent axle 111 connects connecting rod 112; Connecting rod 112 connects plunger 113 through plunger pin 114, and stretch out outside the housing 100 on the top of curved bar 111, in the time of 110 work of needs piston cylinder; Turning crankshaft 111, bent axle 111 drives plunger 113 through connecting rod 112 and makes back and forth movement.
In sum; Be merely preferred embodiment of the present invention; Be not to be used for limiting the scope that the present invention implements, all equalizations of doing according to the described shape of claim scope of the present invention, structure, characteristic and spirit change and modify, and all should be included in the claim scope of the present invention.
