Abstract

A reciprocating-type bidirectional piston pump comprises a pump body, a piston arranged inside and matched with the pump body, and a connecting rod connected with the piston. The piston divides the pump body into a first cavity and a second cavity; a first water pipe and a second water pipe are communicated in the first cavity and the second cavity; water inlets are respectively formed at one end of the first water pipe and at one end of the second water pipe, and water outlets are respectively formed at the other ends of the first water pipe and the second water pipe; and corresponding check valves are respectively formed at the water inlets and the water outlets. The reciprocating-type bidirectional piston pump, provided by the utility model, adopts the piston arranged on the pump body and matching the first water pipe with the second water pipe to conduct the reciprocating movement, thereby enabling the piston pump to simultaneously pump water and drain off water; and in addition, two water holes for water entrance and water exhaust are formed on the pump body and respectively communicated with the water holes formed in the middle positions of the first water pipe and the second water pipe. Compared with the prior art, the reciprocating-type bidirectional piston pump has the advantages of high working efficiency, wide application range, simple structure and low cost.

Further, described first water pipe is provided with the described pump housing is vertical respectively with second water pipe.

Further, first cavity of the described pump housing, second cavity are communicated with the intermediate portion of described first water pipe, second water pipe respectively.

Particularly, not only can intake but also the water hole of water outlet but offer two on the described pump housing, these two water holes are communicated with the water hole that first water pipe, the second water pipe intermediate portion are offered respectively.

Further, described connecting rod is connected with a crank, and described crank is connected with an actuator.

Particularly, described actuator is a motor.

Particularly, described each one-way valve is a T shape part, and is made by rubber material.

Particularly, described each one-way valve place is equipped with two seal rings.

Particularly, the described pump housing, first water pipe and second water pipe adopt the plastic material moulding respectively.

The reciprocating type bidirectional piston pump that the utility model provides adopts first water pipe and second to-and-fro motion of water pipe fitting piston in the pump housing be located on the pump housing, realizes that reciprocating pump draws water and draining simultaneously; Compared with prior art, the utility model high working efficiency, application are extensive, simple in structure, with low cost.

Embodiment

In order to make the purpose of this utility model, technological scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

As Fig. 1～shown in Figure 6, a kind of reciprocating type bidirectional piston pump that the utility model embodiment provides, the connecting rod 12 that comprises the pump housing 1, is located at the described pump housing 1 interior piston 11 with matching and is connected with described piston 11, described piston 11 is divided into first cavity 13 and second cavity 14 with the pump housing 1; Described first cavity 13 is communicated with one first water pipe 2, and described second cavity 14 is communicated with one second water pipe 3; Described first water pipe 2 is identical structure with second water pipe 3, and an end of described first water pipe 2 is that water intake 21, the other end are water outlet 22, and same, an end of described second water pipe 3 is a water intake 31, and the other end is a water outlet 32; Further, be provided with corresponding one-way valve 4 respectively in described

water intake

21,31 and

water outlet

22,32 places, this one-way valve 4 is a T shape member, and make by soft material, as rubber material, certainly, this one-way valve 4 also can adopt the structure of existing controlled water flow one-way flow.

Particularly, described first water pipe 2 and second water pipe 3 intersect vertical setting with the described pump housing 1 respectively, first cavity 13 of the described pump housing 1, second cavity 14 are communicated with the intermediate portion of described first water pipe 2, second water pipe 3 respectively, not only can intake but also the water hole of water outlet but offer two on the described pump housing 1, these two water holes are communicated with the water hole that first water pipe 2, second water pipe, 3 intermediate portions are offered respectively; Described connecting rod 12 is connected with a crank (not shown), and described crank is connected with an actuator, the optional motor of this actuator; In order to prevent leakage from water pump, be respectively equipped with seal ring in the place that leaks easily between described one-way valve 4 places, piston 11 and the pump housing 1, between connecting rod 12 and the pump housing 1 etc.

Further, the described pump housing, first water pipe and second water pipe are respectively by the plastic material moulding, and be with low cost, and have extraordinary chemical resistance, therefore, can be used to pesticide, cleaning liquid etc. and have the very corrosive liquid of extensive chemical.In addition, the utility model can be applicable to traditional unidirectional all applications that go out water pump, significantly improves working efficiency.
