The present invention relates to a kind of balanced type break valve, particularly a kind of balance double-sleeve type throttle check regulates multiplex valve, is widely used in the industries such as oil, chemical industry.
Background technique
At present, in the production flow line of the industries such as oil, chemical industry, often to use cut-off modulating valve and throttle valve, and then realize respectively cut-off, adjusting and throttling function.Adopt respectively cut-off modulating valve and throttle valve, take larger pipeline space, inconvenient operation, has also increased cost of production.
In addition, traditional stop valve is to realize sealing by flap and coordinating of valve seat, and flap bears from the axial force of medium larger, is unfavorable for opening and closing valve.
Summary of the invention
The object of the invention is in order to provide a kind of balance double-sleeve type throttle check of multi-purpose valve to regulate multiplex valve.
Technological scheme of the present invention is:
A kind of balance double-sleeve type throttle check regulates multiplex valve, comprise valve body, being located at valve body enters, the end flange of liquid outlet, be located at the spool in valve body, be located at the valve gap on valve body top, the valve rod being connected with spool through valve gap, valve gap top is built-in with Stem Mut and the thrust ball bearing matching with valve rod, thrust ball bearing top is provided with bearing gland, Stem Mut outer surface of upper fitting operation handle, its special way is: the guide sleeve that is provided with overflow hole in described valve body, described spool bottom is provided with cavity, and offer overflow hole on the wall of the chamber of described cavity, described guide sleeve inwall and spool outer wall closely cooperate and realize the sealing of valve body, described valve gap below is fixedly connected with anti-rotation guide rod, the pilot hole that is communicated with cavity described in its underpart is offered in corresponding described anti-rotation guide rod position, described spool top.
Above-mentioned balance double-sleeve type throttle check regulates multiplex valve, and difference pile-up welding hard alloy on the sealing contact surface of described guide sleeve inwall and spool outer wall, to improve erosion resistance and sealability.
Above-mentioned balance double-sleeve type throttle check regulates multiplex valve, between described guide sleeve bottom and valve body, is provided with pad, on the sealing contact surface of described guide sleeve and valve body, spool, is respectively equipped with O-ring seals, to improve the sealability of valve body.
Above-mentioned balance double-sleeve type throttle check regulates multiplex valve, on the sealing contact surface of described valve gap and valve body, valve rod, is respectively equipped with O-ring seals, to improve the sealability of valve body.
The invention has the beneficial effects as follows:
1, the sealing between spool and guide sleeve, has replaced the sealing configuration form of traditional flap and valve seat, adopts side seal, bears the radial force from medium, and strength is little, and flow is easy to control, simple in structure, sealing is reliable.
2, the pilot hole arranging on spool not only plays the effect of guiding anti-rotation, also has equalizing orifice effect, reaches self balancing object, and the steering force when reducing greatly valve opening and closing especially, in the situation that pressure medium is higher, opens and closes flexibly, easy and simple to handle.
3, the overflow hole on spool and guide sleeve cooperatively interacts and realizes throttling, multistage regulatory function, this valve set cut-off, throttling, regulatory function are in one, on same deck valve door, realize, multi-purpose valve has been saved pipeline operation space, has reduced manufacturing cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: valve body 1, end flange 2, pad 3, O-ring seals 4, O-ring seals 5, guide sleeve 6, spool 7, cartridge cover 8, O-ring seals 9, anti-rotation guide rod 10, O-ring seals 11, O-ring seals 12, stud 13, nut 14, valve gap 15, bearing gland 16, Cock screw 17, valve rod protective housing 18, valve rod 19, flat key 20, handle 21, Stem Mut 22, thrust ball bearing 23, O-ring seals 24, overflow hole 25, overflow hole 26, screw 27, pilot hole 28.
Embodiment
As shown in the figure, this balance double-sleeve type throttle check regulates multiplex valve, comprise valve body 1, being welded in valve body 1 enters, the end flange 2 of liquid outlet, be located at the spool 7 in valve body 1, utilize stud bolt 13 and nut 14 to be fixed on the valve gap 15 on valve body 1 top, the valve rod 19 being connected with spool 7 through valve gap 15, spool 7 is provided with cartridge cover 8 and utilizes cartridge cover 8 and screw 27 is fixed valve rod 19 bottoms, valve gap 15 tops are built-in with Stem Mut 22 and the thrust ball bearing 23 matching with valve rod 19, thrust ball bearing 23 tops are provided with bearing gland 16, Stem Mut 22 outer surface of upper utilize flat key 20 to connect handle 21 fixing by Cock screw 17, described valve rod 19 and Stem Mut 22 top ends are installed valve rod protective housing 18.
In described valve body 1, be provided with the guide sleeve 6 of overflow hole 25, described spool 7 bottoms are provided with cavity, and offer overflow hole 26 on the wall of the chamber of described cavity, described guide sleeve 6 inwalls and spool 7 outer walls closely cooperate and realize the sealing of valve body 1, described valve gap 15 belows are fixedly connected with anti-rotation guide rod 10, and the pilot hole 28 that is communicated with cavity described in its underpart is offered in corresponding described anti-rotation guide rod 10 positions, described spool 7 tops.Difference pile-up welding hard alloy on the sealing contact surface of described guide sleeve 6 inwalls and spool 7 outer walls.In order to improve the overall sealing performance of valve body 1, between described guide sleeve 6 bottoms and valve body 1, be provided with pad 3, on the sealing contact surface of described guide sleeve 6 and valve body 1, spool 7, be respectively equipped with O- ring seals 4,11,5,9, on the sealing contact surface of described valve gap 15 and valve body 1, valve rod 19, be respectively equipped with O- ring seals 12,24.
