Abstract

The utility model relates to a three-cylinder piston pump which comprises a pump housing. The pump housing is internally provided with three piston cylinders used for generating a pushing force and a cavity at the side of the pushing force of the three piston cylinders. The cavity is internally provided with a water inlet valve shelf. The water inlet valve shelf divides the cavity into a water inlet chamber and a water outlet chamber. The water inlet valve shelf is internally provided with a through hole. A non-return valve sheet is provided in the through hole. A water inlet is provided on the pump housing of a side edge of the water inlet valve shelf. The water inlet is connected to the water inlet valve shelf. A water outlet is provided on the pump housing of the water outlet chamber. The three-cylinder piston pump has the advantages that after the design that a water inlet valve and a water outlet valve are in the same cavity is used, compared with the previous structure, the valve installation is convenient, the service life is long, the load is light, etc.

The model utility content
The purpose of this utility model is in order to solve the existing defective of reciprocating pump in the prior art, to provide a kind of inlet/outlet valve to solve the problems referred to above at three cylinder reciprocating pumps of same cavity.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of three cylinder reciprocating pumps, comprise pump case, be provided with in the pump case for generation of three piston cylinders of thrust and the cavity of three piston cylinder thrust direction one sides, it is characterized in that, be provided with in the described cavity into the water vavle shelf, the water inlet vavle shelf is divided into water-inlet cavity and water chamber with cavity, be provided with through hole in the described water inlet vavle shelf, be provided with check valve sheet in the through hole, be provided with water intake on the pump case of described water inlet vavle shelf side, described water intake connects the water inlet vavle shelf, is provided with water outlet on the pump case of described water chamber.
Above-mentioned a kind of three cylinder reciprocating pumps is characterized in that: be provided with in the described cavity and three three water inlet vavle shelves that piston cylinder is corresponding.
Above-mentioned a kind of three cylinder reciprocating pumps is characterized in that: described three the water inlet vavle shelves and on every side the slit between the housing be provided with the outlet valve pad, described outlet valve pad is connected on the water vavle shelf by spring.
Above-mentioned a kind of three cylinder reciprocating pumps, it is characterized in that: described piston cylinder comprises bent axle, connecting rod and plunger, and bent axle connects connecting rod, and connecting rod connects plunger by plunger pin, and stretch out outside the housing on the top of bent axle.
The beneficial effect that the utlity model has: adopt inlet/outlet valve after the design of same cavity, and compare with pre-structure, valve installation is easy, long service life, the advantage such as load is light.
Description of drawings
Fig. 1 is sectional view of the present utility model.
Embodiment
Further understand and understanding for making structure characteristic of the present utility model and the effect reached had, cooperate detailed explanation in order to preferred embodiment and accompanying drawing, be described as follows:
Referring to Fig. 1, a kind of three cylinder reciprocating pumps, comprise pump case 100, be provided with in the pump case 100 for generation of three piston cylinders 110 of thrust and the cavity 120 of three piston cylinder 110 thrust directions one sides, three piston cylinders 110 are done back and forth movement by pushing piston and are produced thrust, and the liquid in the cavity 120 is released.
Be provided with in the cavity 120 into water vavle shelf 200, water inlet vavle shelf 200 is divided into water-inlet cavity 121 and water chamber 122 with cavity 120, be provided with through hole in the water inlet vavle shelf 200, one 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 so that liquid can only flow into the water-inlet cavitys 121 and can not allow liquid be back to water intake 300 from water-inlet cavity 121 from water intake 300, be provided with water intake 300 on the pump case 100 of water inlet vavle shelf 200 sides, water intake 300 connects water inlet vavle shelf 200, is provided with the water outlet (not shown) on the pump case 100 of water chamber 122.
In the time of work, when three piston cylinders 110 are inhaled backward, liquid enters into the through hole in the water vavle shelf 200 from water intake 300, and then enter into water-inlet cavity 121 by check valve sheet 210, this moment, three piston cylinders 110 pushed away forward, liquid is along with thrust is passed from water-inlet cavity 121 in the inflow of the gap between water vavle shelf 200 and the pump case 100 water chamber 122, simultaneously because check valve sheet 210 has been blocked the through hole of water inlet vavle shelf 200, so that liquid can not be back to water intake 300 places.
Be provided with three the water inlet vavle shelves 200 corresponding with three piston cylinders 110 in the cavity 120, flow into the water-inlet cavitys 121 from water intake 300 so that liquid can be more smooth.
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 water vavle shelf 200 by spring 230, when piston cylinder 110 does not produce thrust, outlet valve pad 220 is being blocked under the effect of spring 230 into water vavle shelf 200 and the slit between the housing 100 on every side, so that liquid outside seepage not, and when piston cylinder 110 produces thrust, 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 by plunger pin 114, stretch out outside the housing 100 on the top of bent axle 111, in the time of 110 work of needs piston cylinder, turning crankshaft 111, bent axle 111 drives plunger 113 by connecting rod 112 and makes back and forth movement.
In sum, it only is preferred embodiment of the present utility model, be not to limit the scope that the utility model is implemented, all equalizations of doing according to the described shape of the utility model claim scope, structure, feature and spirit change and modify, and all should be included in the claim scope of the present utility model.
