Abstract

The utility model discloses a plunger which comprises a plunger body. The plunger body adopts a hollow structure, one end of the plunger body is closed, and the other end of the plunger body is clamped with a steel ball. The hollow structure adopted by the plunger is light in weight relative to a solid structure. Therefore, the plunger is light in weight, clamping of machinery is convenient in a machining process, machining difficulty of the plunger is further reduced, and machining efficiency is improved. Due to the fact that the plunger adopts the structure that one end of the plunger is closed, and the other end of the plunger is clamped with the steel ball, in a plunger production process, a mechanical operation is adopted to clamp the steel ball to the plunger body, and a circular seal structure is formed. The circular seal structure can not only simplify the structure of the plunger, but also reduce the machining difficulty of the plunger to a great extent. In addition, due to the adopted hollow structure, material needed to produce the plunger is reduced, and manufacture cost is reduced. Therefore, due to the fact that the hollow structure is adopted by the plunger, the problems that a plunger machining operation is difficult and manufacture cost is high are solved.

Description

A kind of plunger

Technical field

The utility model relates to the jetting machine equipment technical field, more particularly, and particularly a kind of plunger.

Background technique

Jetting machine is to make high-pressure plunger pump produce the machine that high pressure water washes body surface by power plant.It can be peeled off dirt, washes away, and reaches the purpose on cleaning of objects surface.Because be to use water jets under high pressure cleaning dirt, so high-pressure wash also is one of cleaning mode of universally acknowledged most scientific, economy, environmental protection.

One of of paramount importance parts are exactly plunger in the jetting machine, and plunger is the critical piece that produces high-pressure water flow.In the prior art, the production of plunger is to adopt the embryo spare of solid integral body to process, and its quality of processing is larger, has caused comparatively difficulty of plunger processing, causes work efficiency lower.And, adopting solid construction, manufacture cost also can be corresponding higher.

In sum, how to solve comparatively difficulty of plunger machining operation, the problem that manufacture cost is higher becomes those skilled in the art's problem demanding prompt solution.

The model utility content

The technical problems to be solved in the utility model is for providing a kind of plunger, and this plunger can solve comparatively difficulty of plunger machining operation, the problem that manufacture cost is higher by its structural design.

For solving the problems of the technologies described above, the utility model provides a kind of plunger, is installed in the jetting machine, for generation of high-pressure water flow, comprises piston body,

Described piston body is hollow-core construction;

The one end sealing of described piston body, its other end is connected with steel ball.

Preferably, the end that described piston body is connected with steel ball is opening end, and the port is provided with the draw-in groove of annular, and described steel ball is connected in the described draw-in groove.

Preferably, described steel ball is the GR15 steel ball.

The utility model provides a kind of plunger, is installed in the jetting machine, for generation of high-pressure water flow, comprises piston body.In the utility model, piston body has adopted hollow-core construction.As a kind of general knowledge as can be known, for measure-alike parts, its hollow-core construction is for solid construction, and quality can descend on certain degree to some extent.So, in the utility model, the plunger quality lightens, and is convenient to mechanical adding and holds when machining, thereby reduce its difficulty of processing, improves work efficiency.Piston body adopts the sealing of one end, and the other end is connected with the structural design of steel ball, when plunger is made, uses mechanically actuated that steel ball is snapped on the piston body, makes it form the structure of ring packing.This structural design not only can be simplified the structure of plunger, has also reduced dramatically the difficulty of processing of plunger.And owing to adopt hollow-core construction, it is made required material and reduces the manufacture cost reduction.In sum, the utility model can solve comparatively difficulty of plunger machining operation, the problem that manufacture cost is higher owing to adopted hollow-core construction.

Embodiment

Core of the present utility model is for providing a kind of plunger, and the piston body of this plunger adopts the hollow-core construction design, by this structure, can solve comparatively difficulty of plunger machining operation, the problem that manufacture cost is higher.

In order to make those skilled in the art understand better the technical solution of the utility model, lower

The utility model is described in further detail with specific embodiment by reference to the accompanying drawings for face.

Please refer to Fig. 1 and Fig. 2, wherein, Fig. 1 is the structural representation of piston body among a kind of embodiment of the utility model; Fig. 2 is the structural representation of plunger among a kind of embodiment of the utility model.

The utility model provides a kind of plunger, is installed in the jetting machine, for generation of high-pressure water flow, comprises piston body 1.In the utility model, piston body 1 has adopted hollow-core construction.As a kind of general knowledge as can be known, for measure-alike parts, its hollow-core construction is for solid construction, and quality can descend on certain degree to some extent.So, in the utility model, the plunger quality lightens, and is convenient to mechanical adding and holds when machining, thereby reduce its difficulty of processing, improves work efficiency.

Particularly, piston body 1 adopts the sealing of one end, and the other end is connected with the structural design of steel ball 2, when plunger is made, uses mechanically actuated that steel ball 2 is snapped on the piston body 1, makes it form the structure of ring packing.This structural design not only can be simplified the structure of plunger, has also reduced dramatically the difficulty of processing of plunger.And owing to adopt hollow-core construction, it is made required material and reduces the manufacture cost reduction.In sum, the utility model can solve comparatively difficulty of plunger machining operation, the problem that manufacture cost is higher owing to adopted hollow-core construction.

In an embodiment of the present utility model, the end that piston body 1 is connected with steel ball 2 is opening end, and the port is provided with the draw-in groove 3 of annular, and steel ball 2 is connected in the draw-in groove 3.Draw-in groove 3 can be processed into the structure with curve bath, thereby improves the cooperate degree of itself and steel ball 2.So, not only can guarantee that 3 pairs of steel balls 2 of draw-in groove have stable adding and hold (clamping) effect, can also further improve the sealing effect of 2 pairs of piston body 1 of steel ball.

Particularly, steel ball 2 is used the GR15 steel ball instead, adopts Bearing Steel as the making material of steel ball 2, and its hardness is higher, and is not yielding.
