Abstract
Disclosed is a couple-clip rotary type multi-valve check valve which is a value with unique conception. The utility model is used in conduit systems conveying oil, water and various gaseous mediums. The value comprises two rectangular holes, six incomplete bow shaped holes and eight valve flaps whose shapes are corresponding to the shapes of the holes; the two rectangular and six incomplete bow shaped holes are formed by dividing a valve seat by a latticed ventral shield. Each valve flap and the valve seat are connected as a whole via a lone shaft pin. The utility model has the advantages of simple and compact structure, easy fabrication, light weight, convenient maintenance, low cost and material saving. The weight of a couple-clip rotary type multi-valve check valve of Dg 1200 is 0.5t which is one seventeenth as heavy as the weight of a swing multi-valve check valve with the same caliber. The length of the utility model is only one twenty-fifth as long as the length of a swing multi-valve check valve, and the utility model is a universal product for industry.
Description
The invention belongs to model utility, is a kind of check valve that is used for pipe-line system.For guaranteeing stable processing technique and equipment safety operation, check valve is a kind of important auxiliary products in industrial production and construction project.
The check valve structure that prior art is used on the large diameter pipeline is huge and heavy, and installation and processing and maintenance are all very complicated, useless worker, waste material, many lobes of rotary-open type check valve of Dg1200 8.7t that weighs when useless, and length is 2300mm.
The present invention is directed to shortcomings such as the above existing check valve structure complexity of Dg700, heaviness, change former many lobes of rotary-open type check valve into two rectangulars and six incomplete arc flaps as shown, cancelled original huge valve body, replaced a garden plate-like valve seat, simplified the structure, saved material, saved the fabricating yard, be convenient to maintenance is installed, a Dg1200's is 0.5t to pressing from both sides rotary many lobes check valve weight, only be 1/17 of many lobes of rotary-open type check valve weight, length only is 1/25 of rotary-open type.This is a kind of universal product, industrial of many uses.
Description of drawings: Fig. 1. to pressing from both sides rotary many lobes check valve top view, Fig. 2. to pressing from both sides rotary many lobes check valve A-A sectional drawing.Order by piece number in the accompanying drawing is illustrated model utility invention each several part below: 1. valve seat 2. flaps 3. flaps 4. flaps 5. journal stirrups 6. pillars 7. major axis pins 8. springs.
Be made up of valve seat and flap pressing from both sides rotary many lobes check valve, valve seat 1 is that garden dish is divided into three kinds of difform perforates by a latticed web, two rectangulars, six incomplete arc perforates, with the corresponding flap 2 of 8 perforates of difformity on the valve seat be 4, flap 3 is 2, flap 4 is 2, by corresponding position, divide four groups of settings, after all flaps and journal stirrup link, by journal stirrup 5, pillar 6 and major axis pin 7 link together flap and valve seat.Pillar 6 and valve seat 1 latticed web are that mortise joins, pillar 6 is except that fusing valve seat and flap, when being washed open rotation by fluid, flap plays position-limiting action, guarantee that the flap rotation angle is no more than 90 degree, each major axis pin middle part is equipped with a spring 8, starts when check valve transfers closure to by unlatching soon, on the other hand when flap is opened by closed state, can weaken the percussion of flap, reduce noise and increased the service life pillar.Pillar with holes is respectively established one group everywhere at web, and this pillar and flap journal stirrup fuse by a major axis pin.
Claims (4)
1, to pressing from both sides rotary many lobes check valve, it is characterized in that it is made up of valve seat and flap two large divisions, to be garden dish be separated in correspondence with each other two rectangulars and 6 incomplete arc perforates by a latticed web to valve seat, flap be one group with the corresponding plate of valve seat hole shape.
2, check valve as claimed in claim 1 is characterized in that web respectively is provided with one group of pillar with holes everywhere.
3, check valve as claimed in claim 1 or 2 is characterized in that pillar with holes on the web and flap journal stirrup fuse by a major axis pin.
