It asks.If reduction control element can be saved a large amount of installation space, reduces a large amount of manpowers of operation and speculate.Tradition
By various control element come control function requirement, various functions are made of pipeline control system different valves.Installation space is big,
Pipeline will invest greatly, inconvenient for operation, and maintenance cost is high.
Suitable for the industrial departments such as petroleum, chemical industry, chemical fertilizer, electric power, pesticide, chemical fibre, food, medicine, metallurgy and national defence,
Scientific research, traffic, agricultural or even living facilities pipeline control system,
Utility model content:
The utility model aim be propose a kind of pair of pipe-line system switched, sampled, the multi-functional integration such as blowdown
Integrated control device, especially propose a kind of integrated control valve.
The technical solution of the utility model is a kind of multifunctional control valve, including valve body 2, spool 3, sealing element 4, sealing
Gasket 5, valve rod 7, handwheel 8, valve body fluid passage 10, spool 3；The inlet and outlet of valve inner valve body fluid passage 10 and valve
Connection, spool 3 are controlled in the up and down motion of valve body fluid passage, that is, spool chamber by the valve rod 7 and handwheel 8 fixed with spool, valve
The upper and lower movement position of core 3 corresponds to the conducting and cut-off of valve；The top of spool 3 and valve rod 7 are equipped with sealing element 4, gasket seal 5
Package；The second spool chamber 11, the second spool 12, the second valve rod 13, the second handwheel 14 are additionally provided on valve body；Second spool chamber 11 with
The connection of valve body fluid passage, body base are equipped with blowdown connection, and the import of blowdown connection 1 is connected with valve body fluid passage 10
Logical, the second spool 12 is controlled in the side-to-side movement of the second spool chamber 11 by second valve rod and second handwheel 8 fixed with the second spool
System, the left and right movement position of the second spool correspond to the blowdown connection cut-off and conducting of valve.Blowdown connection can be in main valve conduit
It is sampled and blowdown.
The utility model is intensive into integration switch, sampling, blowdown etc. are multi-functional.Second spool, that is, floating plug closes
It is small to close torque, cuts off good reliability.
Spool and the second spool use the design of O-ring and 5 dual sealing structure of gasket seal, and jam nut is for solid
Determine gasket seal, sealed reliable.
Working principle and process: as shown, opening main valve, the orifice of left end and left end, then the pair of left end is opened
Valve can control blowdown and sampling, the multiple functions such as switch, sampling, blowdown thus may be implemented.
The utility model has the advantages that 1, be intensive into integration switch valve, sampling, blowdown valve etc. are multi-functional, facilitate operation, convenient for peace
Dress, save the cost and space, it is easy to maintenance.2, using dual Seal Design, sealed reliable, long service life.3, whole to adopt
With corrosion-resistance treatment and low temperature resistant processing, corrosion resistance is strong；It is applied widely.
Detailed description of the invention:
Fig. 1 is the cross section structure schematic diagram of the utility model,
Fig. 2 is the cross section structure schematic diagram that the utility model Fig. 1 valve rotates 90 degree.
Specific embodiment:
It is as shown in Figs. 1-2: blowdown connection 1, valve body 2, spool 3, sealing element 4, gasket seal 5, jam nut 6, valve rod 7,
Handwheel 8, nut 9, valve body fluid passage 10, the second spool chamber 11, the second spool 12, the second valve rod 13, the second handwheel 14.
In the multifunctional control valve, including valve body 2, spool 3, sealing element 4, gasket seal 5, valve rod 7, handwheel 8, valve body
Fluid channel 10, spool 3；Valve inner valve body fluid passage 10 is connected to the inlet and outlet of valve, and the fluid in valve body of spool 3 is logical
The up and down motion of road, that is, spool chamber is controlled by the valve rod 7 and handwheel 8 fixed with spool, and valve rod 7 and handwheel are in vertical position；Valve
The upper and lower movement position of core 3 corresponds to the conducting and cut-off of valve；The top of spool 3 and valve rod 7 are equipped with sealing element 4, gasket seal 5
Package；The second spool chamber 11, the second spool 12, the second valve rod 13, the second handwheel 14 are additionally provided on valve body；Second spool chamber 11 with
The connection of valve body fluid passage, body base are equipped with blowdown connection, and the import of blowdown connection 1 is connected with valve body fluid passage 10
