Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
Be structural representation of the present utility model as shown in Figures 1 to 5,
Reference character is wherein: lid 1, low pressure area 1a, zone of high pressure 1b, water intake 11, water outlet 12, sidewall 13, demarcation strip 14, flow distribution plate 15, erection column 16, mounting hole 16a, splitter box 16b, fixing along 17, fixed hole 17a, stiffening rib 18, pressure releasing chamber 2, attachment hole 2a, top cover 21, relief hole 21a, Regulation spring 22, spool 23.
As shown in Figures 1 to 5,
A kind of diaphragm pump cover with pressure relief of the present utility model, include lid 1, lid 1 is shaped with the water intake 11 and water outlet 12 that are made into integration with described lid 1, water intake 11 and water outlet 12 are positioned at the both sides of lid 1, lid 1 periphery is shaped with sidewall 13, wherein, the inner top surface of lid 1 is integrally shaped with demarcation strip 14, the inside of lid 1 is divided into low pressure area 1a and zone of high pressure 1b by this demarcation strip 14, be shaped with the mouth of pipe be connected with water intake 11 in the 1a of low pressure area, zone of high pressure 1b is shaped with the mouth of pipe be connected with water outlet 12; Lid 1 is arranged pressure releasing chamber 2, this pressure releasing chamber 2 is connected with described zone of high pressure 1b by attachment hole 2a, top cover 21 is covered with outside pressure releasing chamber 2, this top cover 21 is provided with relief hole 21a, attachment hole 2a place is provided with spool 23, be provided with Regulation spring 22 in pressure releasing chamber 2, one end and the spool 23 of Regulation spring 22 offset, and its other end and top cover 21 offset.
In embodiment, be shaped with flow distribution plate 15 in the 1a of low pressure area, one end of flow distribution plate 15 is connected with described demarcation strip 14, and its one end is connected with described sidewall 13, forms liquid storage chamber between adjacent flow distribution plate 15.
The number of flow distribution plate 15 is 6 to 12, and flow distribution plate 15 is distributed in described low pressure area 1a radially.
Low pressure area 1a is divided into multiple liquid storage chamber by flow distribution plate 15, current flow into after the 1a of low pressure area through water intake 11, water impact can be slowed down when each flow distribution plate 15, thus reduce current noise, current are through liquid storage chamber simultaneously, form vortex shape because the obstruction being subject to front flow distribution plate 15 produces backflow, reduce further the impact force of current, improve the working life of pump cover.
In embodiment, demarcation strip 14 is in cirque structure, and zone of high pressure 1b is positioned at the inside of demarcation strip 14 cirque structure, and low pressure area 1a is positioned at the outside of demarcation strip 14 cirque structure.

In embodiment, the outer of lid 1 is formed fixing along 17, fixes and is evenly provided with fixed hole 17a along on 17.
In embodiment, lid 1 is shaped with stiffening rib 18.The setting of stiffening rib 18 can improve the intensity of lid 1, thus improves its working life.
Working principle:
During normal work: one end and the top cover 21 of Regulation spring 22 offset, and its other end and spool 23 offset, and due to the elastic force effect of Regulation spring 22, spool 23 blocks attachment hole 2a.Water flows into low pressure area 1a from water intake 11, flows out from water outlet 12 by zone of high pressure 1b.
When the overpressure of zone of high pressure 1b, namely the pressure of zone of high pressure 1b is greater than Regulation spring 22 elastic force, and the pressure in the 1b of zone of high pressure will overcome the acting of Regulation spring 22 elastic force and compression adjustment spring 22, be backed down by spool 23.After spool 23 is opened, zone of high pressure 1b is connected by attachment hole 2a with pressure releasing chamber 2, and the water of zone of high pressure 1b will flow into pressure releasing chamber 2 and flow out from the relief hole 21a of pressure releasing chamber 2 top cover 21, thus completes self-relieving process, ensures the safe handling of diaphragm pump.
When the medium in diaphragm pump changes other liquid of work or gas, self-relieving process can be completed by said process is the same, thus avoid pump cover answer internal pressure too high and damage, and then improve the working life of pump cover.
Most preferred embodiment of the present utility model is illustrated, and the various change made by those of ordinary skill in the art or remodeling all can not depart from scope of the present utility model.
