Abstract
A plunger and water inlet and outlet valve assembly of a cleaning machine comprises a pump body. The pump body is connected with a pump head, a plunger is arranged in the pump body and is connected with a piston rod, a water inlet one-way valve component is arranged in an inner hole of the plunger, and a water outlet one-way valve is arranged in the pump head. The plunger and water inlet and outlet valve assembly of the cleaning machine is characterized in that the plunger is sleeved at the tail end of the piston rod and is screwed down by a nut, the water inlet one-way valve component comprises a valve seat arranged in the inner hole of the plunger, a valve plate and a spring are arranged on the valve seat, a valve bonnet is capped under the valve seat and is fixed by a press cap. Compared with the conventional piston pump, the plunger and water inlet and outlet valve assembly of the cleaning machine is low in accuracy requirement, easy to process, small in size, light in weight and reliable in integral sealing.
Description
Technical field
The utility model relates to a kind of plunger and turnover water valve of washing machine.
Background technique
At present, the pump that is used for washing machine generally all is a reciprocating pump, but traditional reciprocating pump working pressure is low, and movement velocity is slow, and volume is big, and running parameter is limited in scope.Therefore, in recent years, increasing use plunger pump, still, its plunger of the plunger pump of existing technology directly is connected with bent axle through connecting rod, and required precision is high, and processing is difficult for, and volume is big, and Heavy Weight is restricted during use.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming of prior art, provides a kind of novel structure unique, reliable performance, and required precision is low, and is easy to process, and volume is little, the plunger of lightweight a kind of washing machine and turnover water valve.
The technological scheme of the plunger of a kind of washing machine of the utility model and turnover water valve is: comprise the pump housing, the pump housing connects pump head, and plunger is arranged in the pump housing; Plunger connects piston rod, is installed into the water one-way valve assembly in the plunger endoporus, and water one-way valve is installed out in the pump head; It is characterized in that described plunger is placed in piston-rod end, and tighten mutually that described water inlet check valve assembly comprises the valve seat that is installed in the plunger endoporus by nut; Valve block and spring are installed on the valve seat, are buckled with valve bonnet under the valve seat, and fix by pressure cap.
The plunger of a kind of washing machine of the utility model and turnover water valve, plunger is placed in piston-rod end, tightens mutually with nut, and plunger floats in the pump housing; Valve block and spring place on the valve seat, valve bonnet are buckled under the valve seat, with the whole water inlet check valve assembly plunger endoporus of packing into again; Be screwed into the plunger endoporus with pressure cap again, to tighten the into unidirectional valve bonnet of water, its advantage is: plunger floats in the pump housing; Required precision to structural member is low, thereby processing cost is low, and plunger head has the water inlet; The water inlet check valve assembly is loaded in the plunger, goes out water one-way valve and is loaded in the pump head, and the structure that goes out water one-way valve is identical with the structure of water inlet check valve assembly.Pump head is connected by lining with the pump housing, and has respectively attacked screw thread on the water-in and water-out one-way valve seat, dismounting during with convenient for maintaining.Under the identical situation of each parameter of washing machine, this kind structure is more much smaller than the volume of existing reciprocating pump, and is in light weight, and integral sealing is reliable.
The plunger of a kind of washing machine of the utility model and turnover water valve, described valve seat outer wall is equipped with an O type circle, and an O type circle contacts good airproof performance with the sealing of plunger endoporus.The described pump housing connects pump head through lining, is equipped with the 2nd O type circle between the lining and the pump housing, is equipped with the 3rd O type circle between lining and the pump head, and is easy to connect, and sealing is reliable.
