Abstract
The utility model discloses a kind of four-way with special nozzle to dust ball valve, comprise gateway joint, valve body, valve stem seal, butterfly spring, valve rod, valve base, seal ring, valve seat, spool, blowout inlet attack, blowout entrance valve seat and nozzle; Described gateway joint, valve body, valve seat, valve rod, valve stem seal and seal ring together constitute sealing system; Valve body and spool all have passage, on spool and the hole had for installing nozzle and the falcon groove for installing valve rod; Spool does the to-and-fro motion of swing under valve rod drives, respectively with gateway joint and blow out inlet attack and form path, make when respective station works wherein a road medium by and another road medium is blocked; The spout of described nozzle is by Lavalle Surface forming.The four-way of this band special nozzle dusts ball valve medium when the nozzle surface by Lavalle Surface forming, can reduce vibrations and noise, the working life of prolonging nozzle.
Description
Technical field
The utility model relates to a kind of ball valve, and specifically a kind of four-way with special nozzle dusts ball valve.
Background technique
Ball valve (ball valve should be stop valve in extra large work and ship domain), refer to and make open-shut device with the spheroid of band manhole, spheroid rotates with valve rod, to realize the valve of switching motion.
Be defined as in standard GB/T21465-2008 " valve term ": open-shut device (spheroid) is driven by valve rod, and around the valve that square work ball valve rotates as axis.Utilize the regulating and control that also can be used for fluid, wherein firmly seal between V-type ball valve its V-type ball core and metal seat valve of pile-up welding hard alloy and there is very strong shearing force, be specially adapted to the medium such as fibre-bearing, a small solid material.And multi-pass ball valve not only can the interflow of control media, shunting and the switching that flows to flexibly on pipeline, also can close arbitrary passage simultaneously and two other passage is connected.This class valve generally should level be installed in the duct.Ball valve is classified: pneumatic ball valve, electric ball valve, manual ball valve.
The runner of existing four path ball valves mostly is circular prismatic, and this kind of runner is unfavorable for the flow at high speed of powder grain material, and thus medium produces larger noise and vibrations when this kind of runner high speed flowing.
Model utility content
The purpose of this utility model is to provide a kind of four-way with special nozzle to dust ball valve, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technological scheme:
Four-way with special nozzle dusts a ball valve, comprises gateway joint, valve body, valve stem seal, butterfly spring, valve rod, valve base, seal ring, valve seat, spool, blowout inlet attack, blowout entrance valve seat and nozzle; Described gateway joint, valve body, valve seat, valve rod, valve stem seal and seal ring together constitute sealing system; Valve body and spool all have passage, on spool and the hole had for installing nozzle and the falcon groove for installing valve rod; Spool does the to-and-fro motion of swing under valve rod drives, respectively with gateway joint and blow out inlet attack and form path, make when respective station works wherein a road medium by and another road medium is blocked; The spout of described nozzle is by Lavalle Surface forming.
Compared with prior art, the beneficial effects of the utility model are:
The four-way of this band special nozzle dusts ball valve medium when the nozzle surface by Lavalle Surface forming, can reduce vibrations and noise, the working life of prolonging nozzle.
Accompanying drawing explanation
Fig. 1 is that the four-way of band special nozzle dusts the front sectional view of ball valve.
Fig. 2 is that the four-way of band special nozzle dusts the side view cutaway drawing (when removing gateway joint) of ball valve.
Fig. 3 is the sectional view of special nozzle.
In figure: 1-gateway joint, 5-valve body, 6-valve stem seal, 8-butterfly spring, 10-valve rod, 11-valve base, 12-seal ring, 13-valve seat, 14-spool, 15-blow out inlet attack, 17-blows out entrance valve seat, 20-nozzle, 21-Lavalle curved surface.
Embodiment
Be described in more detail below in conjunction with the technological scheme of embodiment to this patent.
Refer to Fig. 1-3, four-way with special nozzle dusts a ball valve, comprises gateway joint 1, valve body 5, valve stem seal 6, butterfly spring 8, valve rod 10, valve base 11, seal ring 12, valve seat 13, spool 14, blowout inlet attack 15, blowout entrance valve seat 17 and nozzle 20; Described gateway joint 1, valve body 5, valve seat 13, valve rod 10, valve stem seal 6 and seal ring 12 together constitute sealing system; Valve body 5 and spool 14 all have passage, on the spool 14 and hole had for installing nozzle 20 and the falcon groove for installing valve rod 10; Spool 14 does the to-and-fro motion of 90-degree rotation under valve rod 10 drives, respectively with gateway joint 1 and blow out inlet attack 15 and form path, make when respective station works wherein a road medium by and another road medium is blocked; The spout of the nozzle 20 be made up of high-abrasive material is formed by Lavalle curved surface 21.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned mode of execution, in the ken that one skilled in the relevant art possesses, can also makes a variety of changes under the prerequisite not departing from this patent aim.
