Abstract
The utility model relates to a spring reset half-ball type check valve for a diaphragm pump, which is fixed to the position of a liquid inlet and outlet by a pump body, a flange plate, etc. The utility model is characterized in that a reset body with a ball and arc shape support rib is fixed on a position limited support; a half-ball valve gate is fixed on the elastic reset body. When infusion, the half-ball valve gate and a ball-shaped valve gate shim plate are pressed and jointed together by making use of the elastic force of the support rib on the elastic reset body, playing the action of sealing. The check valve which can be widely used for various diaphragm pumps has the advantages of easy fabrication, corrosion resistance and low cost.
Description
The utility model belongs to the improvement of the central valve of liquid capacity-changing mechanical.
At single diaphragm pump, in the middle of the two diaphragm pump, liquid entering hole and liquid outlet place are critical components by the one-way cock of dress.Because pump needs frequent the unlatching when work, closing one-way valve could go out liquid by suction pump.So just need one-way valve that good sealing property and fabulous rebound elasticity are arranged.Generally all adopted metal spring to force the one-way cock resilience in the past, but carry when having than strongly corrosion liquid if desired, spring will be corroded bad very soon, make its one-way valve ineffective.
It is timely, corrosion-resistant that the purpose of this utility model provides a kind of switching return, the elastic reset one-way valve of long good airproof performance of life-span.
Technological points of the present utility model is to adopt at diaphragm pump liquid entering hole and liquid outlet place to fix one by the pump housing and flange plate and have the elastic reset body of spherical arc shape supporting rib by spacing supporting element and, and the fixing one-way valve that is combined into of the Half ball valve on the substrate of elastic reset body.
Fig. 1 is an elastic reset one-way valve schematic representation
Fig. 2 is that the elastic reset one-way valve is installed in the diaphragm pump by the dress schematic representation.
Fig. 3 is that elastic reset one-way valve A is to schematic representation.
Below by accompanying drawing the utility model is described further, (1) is spacing support among the figure, its position is limited by the boss on boss on the pump housing (9) and the flange plate (10), in the middle of the spacing support is that a hole (2) is used to pass through liquid, outer side surface has all grooves ［ 3 ］, is used for fixing the boss ［ 4 ］ on the elastic reset body upper support muscle top that has the spherical arc shape supporting rib.Elastic reset body middle part is the spherical arc shape supporting rib (5) more than three or three, and the bottom is a substrate (6), in the middle of the substrate hole, a garden (7) is arranged, in the hole, garden by adorning a Half ball valve (8).Half ball valve is fitted on the Half ball valve backing plate (11) under the elastic reaction by the supporting rib on the elastic reset body at ordinary times, when liquid entering hole is inhaled into, push Half ball valve when liquid open and enter the pump housing, when pressure is fitted less than the elasticity rear quarter valve and the valve backing plate of elastic reset body, play the effect of leakproof one-way valve, drive at motor connection lever by the pump inner septum later on and move up and down, when changing the pump internal volume, the one-way valve that liquid is pushed the liquid outlet place open pumps.Entire pump liquid process is the motion of barrier film and is installed in liquid entering hole and the unlatching of liquid outlet place one positive one anti-two elastic reset one-way valves, closes and finish.The substrate of elastic reset body and spherical arc shape supporting rib can be used the elastic material once die stamping forming, and Half ball valve can be made with materials such as rubber, plastics, nylon, teflon, potteries according to its working pressure and the chemical property of carrying liquid.
The utility model has the advantages that simple in structurely, easy to manufacture, cost is low, corrosion-resistant, the life-span is long, can be widely used in the various membrane pumps, especially uses when conveying corrosive liquid.
