Abstract
The utility model relates to a rubber hose valve which is a stop valve for fluid operation. The rubber tube valve comprises valve rods and valve cores which are assembled on an upper valve body and a lower valve body, wherein, the valve rods is assembled together with a big threaded rod and a small threaded rod, via threads; the outer circumference of the big threaded rod is connected with a movable plate, via threads; the movable plate is fixedly into one body with a draw rod and a lower pressing plate; the small threaded rod is directly hinged with an upper pressing plate; the valve cores are made from rubber hoses whose both ends are provided with flanges. The utility model has the advantages of simple structure, convenient maintenance, reliable sealing performance and long service life; the fabricating cost of the rubber hose valve is far lower than the fabricating cost of a copper valve or a stainless steel valve or a diaphragm valve; the problems of abrasion and dripping of a butterfly valve are solved fundamentally.
Description
The utility model relates to a kind of stop valve that is used for the fluid operation, particularly a kind of bellow type or straighttube-type rubber tube valve.
At present, the stop valve that is widely used in departments such as oil, chemical industry, light textile, medicine, food, papermaking, boats and ships, metallurgy, mine, water supply and sewage and sewage furification has many kinds, and is wherein particularly general with the application of gate valve and butterfly valve.For preventing corrosion and improve sealing reliability that its material is often selected copper or stainless steel for use, so manufacture cost is generally higher.But the valve of said structure still exists because of wearing and tearing and produces weeping.The weeping that produces in the leakage of lubricating oil in the transmission device, particularly fluid operation tends to reflect and the quality of product.For overcoming above-mentioned defective, once had various forms of membrane valves to occur, but the structure of these membrane valves is complicated, so manufacture cost is also higher.
The purpose of this utility model provides a kind of rubber tube valve, and it is simple in structure, and is easy to maintenance, and its manufacture cost is far below copper valve, Stainless Steel Valve and membrane valve, and sealability is reliable, fundamentally solved the wearing and tearing water clock problem of butterfly valve, improves the working life of valve.
The purpose of this utility model is achieved in that this device comprises valve rod and the spool that is assembled in the upper and lower valve body, wherein valve rod is fitted together by thread set by big screw rod and small screw, big screw rod excircle has plate by spiral marking connection, moving plate utilizes pull bar and press table to be loaded into one, small screw is direct and top board is hinged, and the sebific duct that spool adopts two ends to have flange is made.
Because the utility model adopts valve rod that big screw rod and small screw fit together and special glue pipe type spool, and utilization is installed in the extruding force that the upper and lower pressing plate on the large and small screw rod produces respectively, make the sebific duct closure reach the purpose of valve closing, so can make this device operation light, regulate highly sensitively, sealing is reliable.Because of the glue pipe type spool is changed easily, simple in structure, wear-resisting, corrosion-resistant, acid resistant alkali, the volume of valve body can obviously reduce, and can use for a long time, so this valve is when improving working life, can also significantly reduce manufacture cost and maintenance expenses, therefore, the utility model can replace existing copper valve, Stainless Steel Valve, butterfly valve and membrane valve, is easy to apply.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 a is a kind of concrete structure schematic representation of the present utility model, and b is the sectional view of figure a along the A-A line.
Fig. 2 is the concrete structure schematic representation of bellow type sebific duct.
Fig. 3 is the concrete structure schematic representation of straighttube-type sebific duct.
Describe concrete structure of the present utility model in detail according to Fig. 1-3.This device comprises assembling all-in-one-piece upper valve body 7, following valve body 1, by valve rod and the interlock squeezing unit thereof that big screw rod 9, small screw 8 assemble, the spool that the sebific duct 4 that adopts two ends to have flange is made.Wherein sebific duct 4 can adopt bellows (shown in Figure 2) or straight tube (shown in Figure 3).The interlock squeezing unit comprises and the moving plate 6 of big screw rod 9 excircles by scyewed joint, utilizes pull bar 3 and moving plate 6 to be loaded into one press table 2, directly and the hinged top board 5 of small screw 8.Top board 5 two end part chutes can slide along pull bar 3.During operation, rotate handwheel 10 and drive big screw rod 9 and rotate, and make with it the moving plate 6 that connects respectively by screw thread and small screw 8 in opposite directions or opposite same moved further, drive top board 5, press table 2 in opposite directions or reverse motions, the purpose that reaches extruding or unclamp sebific duct 4.That is the moving press table 2 of shipper pole makes progress on moving plate 6, and it is downward that small screw drives top board 5 simultaneously, extruding sebific duct 4 closures, valve closing.To drive press table 2 downward when moving plate 6 moves down, and small screw 8 drives top boards 5 upwards simultaneously, unclamps sebific duct 4, and sebific duct 4 restores to the original state valve opening under the effect of fluid and sebific duct self elastic force.Making the material of valve body and spool can determine according to usage requirement.
