Description
Technical field
The utility model relates to machining apparatus technical field, is specifically related to one and is provided with neck bush valve.
Background technique
Valve is in fluid system, be used for controlling the direction of fluid, pressure, flow device be the medium in pipe arrangement and equipment (liquid, gas, powder) is flowed or stops and the device of its flow can be controlled.Purposes due to valve is widely, and therefore its role is also very large.In power station, valve can control the running of boiler and steam turbine; In oil, Chemical Manufacture, valve equally also plays the normal operation controlling whole manufacturing mechanism and technological process.Also be so in other departments, existing valve in process of production, because valve is made up of cast iron materials usually, the valve rod of final controlling element is as the balancing boom device of valve, need the size being controlled flow by the lifting of valve rod, because dividing plate is also cast iron once-through usually, easy-to-rust, existing valve solves the problem of corrosion by the mode adding lining, in the market, similar valve installation neck bush, major part adopts neck bush and valve to take out pitch thread cooperating structure, or employing interference fit, or adopt the organization plans such as glue bonding.Easily cause and coordinate insecure obscission, Large Parts Machining screw thread is complicated and processing cost is higher.
Summary of the invention
The technical problems to be solved in the utility model is to provide one and is provided with neck bush valve, it is adopt neck bush and valve to take out pitch thread cooperating structure that the utility model efficiently solves existing lining cover valve major part in course of working, or employing interference fit, or adopt the organization plans such as glue bonding, not only easily cause cooperation insecure, cause the problem of coming off, and the problem that Large Parts Machining screw thread is complicated and processing cost is higher.
The utility model is achieved through the following technical solutions:
One is provided with neck bush valve, comprise valve body (1), valve body (1) both sides port is provided with adpting flange (2), upper end is provided with valve rod mounting hole (3), bottom is provided with and connects base (4), valve body (1) inside is provided with cavity (5), it is characterized in that: described cavity (5) comprises A cavity (51), B cavity (52) is communicated with corresponding port respectively, dividing plate (6) between A cavity (51), B cavity (52) is provided with lining (7), and lining (7) is fixed by fastening piece (8) and dividing plate (6).
The further Technological improvement plan of the utility model is:
Described lining (7) is circumferentially evenly provided with multiple installation through hole (71), lining (7) is fixedly connected with dividing plate (6) by installing the fastening piece (8) arranged in through hole (71), is provided with gasket seal (9) between fastening piece (8) and installation through hole (71).
The further Technological improvement plan of the utility model is:
Described lining (7) bottom is provided with extension limit (72), and lining (7) is coated on dividing plate (6) lower end by extension limit (72).
The further Technological improvement plan of the utility model is:
Described lining (7) is made for copper product.
The utility model compared with prior art, has following obvious advantage:
1, lining of the present utility model is fixed by bolt and dividing plate, and in valve course of working, directly processing mounting holes on dividing plate, not only processes facility, and coordinates firmly, and technique is simple, not only increases equipment efficiency, and has saved processing cost.
2, this practical sleeve arranges extension limit, effectively can prevent the corrosion bottom dividing plate, improves sealing system energy and the working life of valve.
3, the utility model lining uses copper product to make, and makes the control of valve rod more accurate, extends the working life of valve.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is bush structure schematic diagram.
Embodiment
As shown in Figure 1, 2, the utility model comprises valve body 1, valve body 1 both sides port is provided with adpting flange 2, upper end is provided with valve rod mounting hole 3, bottom is provided with and connects base 4, and valve body 1 inside is provided with cavity 5, and described cavity 5 comprises A cavity 51, B cavity 52 is communicated with corresponding port respectively, dividing plate 6 between A cavity 51, B cavity 52 is provided with lining 7, and lining 7 is fixed by fastening piece 8 and dividing plate 6.
Described lining 7 is circumferentially evenly provided with multiple installation through hole 71, and lining 7 is fixedly connected with dividing plate 6 by installing the fastening piece 8 arranged in through hole 71, is provided with gasket seal 9 between fastening piece 8 and installation through hole 71.
Be provided with extension limit 72 bottom described lining 7, lining 7 is coated on dividing plate 6 lower end by extension limit 72.
Described lining 7 is made for copper product.
In practical set process, lining 7 puts into dividing plate 6 endoporus from valve body 1 end opening position, and be locked into neck bush from valve body 1 port side by gasket seal 9 and fastening piece 8, this structure is simply easy to process, installs easily, cost-saving.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art and is realized.
