Abstract
The utility model discloses a closure member of pneumatic diaphragm pump, its upper cover with pneumatic diaphragm pump matches sealedly, and the upper cover is cylinder cavity shape, the closure member is the cylindricality, and its sealed end is equipped with the alloy -layer, the closure member is placed match sealedly in the upper cover. The utility model discloses a closure member shape is changed into cylindrically by original sphere, simplified the course of working, has improved the precision of product part, has hard alloy layer simultaneously, is able to bear or endure the erosion more, has prolonged the life of product, behind the weight gain of part, can carry the high viscosity medium.
Description
Technical field
The utility model relates to diaphragm pump field, more particularly, is a kind of closure member of membrane pump with pneumatic drive.
Background technique
Membrane pump with pneumatic drive is a kind of novel liquid material transfer equipment, the use of the equipment such as alternative submersible pump, pollution discharge pump, centrifugal pump.Little for volume, lightweight, the easy to install feature such as flexibly of this pump.Because it can carry solids-laden fluid, there is not the advantages such as the problem of explosion-proof aspect, generally use in the increasing industry such as petrochemical industry, coating, boats and ships, water treatment, food, papermaking, mine.
Because membrane pump with pneumatic drive is that top lower each two one-way valves carry out work, when the non-return valve of lower end, side sucks medium in open mode, the ball valve of opposite side upper end is also opened simultaneously simultaneously, discharges the medium in this side pump housing.Close if be not closed completely, working efficiency can be caused low.And one-way valve is using ball as closure member, ball can rotate arbitrarily in the middle of work, if the circularity of ball not circle, situation about being not closed completely will be caused to occur, so very high to the requirement of ball, this adds increased the manufacture cost of product.In addition, if when the viscosity of institute's fed sheet of a media is large, because of the lighter in weight of ball, falling speed is slow, and can not close rapidly the one-way valve of lower end, causes equipment normally not run.
Model utility content
In order to solve the problems referred to above that prior art exists, the purpose of this utility model is the closure member proposing a kind of membrane pump with pneumatic drive, and its structure is simple, and improves the precision of product parts.
For achieving the above object, the utility model is solved by following technological scheme:
The closure member of a kind of membrane pump with pneumatic drive of the present utility model, it mates with the upper cover of membrane pump with pneumatic drive and seals, and described upper cover is cylindrical hollow shape; Described closure member is cylindricality, and its sealed end is provided with alloy-layer; Described closure member is placed on coupling sealing in described upper cover.
As preferred technological scheme:
Closure member described in the utility model, described upper cover inwall is provided with some guiding.
Closure member described in the utility model, is provided with stiffening rib in described upper cover.
Closure member described in the utility model, also comprises a sealing seat, is placed on the sealed end withstanding described closure member bottom described upper cover respectively after the two ends of sealing seat put seal ring respectively.
Closure member described in the utility model, the pump housing of described upper cover and described membrane pump with pneumatic drive is joined with bolts.
Owing to adopting above technological scheme, compared with prior art, the closure member of a kind of membrane pump with pneumatic drive of the present utility model, because the shape of closure member spherically changes into cylindrical by original, simplifies course of working, improve the precision of product parts, hard alloy layer, more erosion resistance, extend the working life of product simultaneously, after the weight increase of part, can transfer of highly viscous medium.These advantages, not available for spherical closure member, under the prerequisite not increasing cost, extend the using scope of membrane pump with pneumatic drive, accomplish energy efficiency, have good social effect.

Embodiment
Below with reference to the accompanying drawings and embodiment, the utility model is described in further detail:
As shown in Figure 1, the closure member of a kind of membrane pump with pneumatic drive of the present utility model, it mates with the upper cover of membrane pump with pneumatic drive and seals, and upper cover is cylindrical hollow shape, and namely this upper cover is with work ball room; Closure member is cylindricality, and its sealed end is provided with alloy-layer; Closure member is placed on coupling sealing in upper cover.
As shown in Figure 2, upper cover inwall of the present utility model is provided with some guiding; Stiffening rib 6 is provided with in upper cover.
As shown in Figure 3, when closure member of the present utility model uses, use sealing seat 3, be placed on the sealed end withstanding closure member 4 bottom upper cover 5 respectively after the two ends of sealing seat 3 put O RunddichtringO 2 respectively, upper cover 5 is joined with bolts with the pump housing 1 of membrane pump with pneumatic drive.
During assembling, first on request, the pump housing is assembled.Then cylindricality closure member 4 is loaded in the work ball room of upper cover 5, then O RunddichtringO 2 two is placed on the two sides of sealing seat 3 respectively, then place it in the bottom of upper cover 5; The opposite side of upper cover 5 is installed too; Then the pump housing assembled and upper cover 5 are connected and fixed up and down with bolt.
The pump housing is identical with lower cover portion separation structure form, and assembly process is consistent with the installation of upper cover, install rear connect with bolt and fastening after, diaphragm pump has been assembled.
But above-mentioned embodiment is exemplary, being to better enable those skilled in the art understand this patent, can not being interpreted as it is restriction this patent being comprised to scope; As long as according to this patent disclose any equivalent change done or the modification of spirit, all fall into the scope that this patent comprises.
Claims (5)
