Abstract
The utility model discloses and it is a kind of with valve rod protection heavy caliber Y-shape sizing material valve, it includes：Valve body, valve body connect valve deck, and valve seat and flap, flap connection valve rod are set in valve body, and the flap top is equipped with inner sleeve, and the lower part of valve deck is equipped with outer sleeve, and inner sleeve is stretched into outer sleeve, and inner sleeve can be slided with respect to outer sleeve.Its valve rod is not easy flexural deformation, ensure that valve clack sealing surface is concentric with sealing surface of seat, and good sealing function is played when valve is closed, and improves the service life of valve.
Description
Technical field
It the utility model is related to a kind of valve, more particularly to a kind of heavy caliber Y-shape sizing material valve with valve rod protection.
Background technology
Regulating valve currently on the market mainly has single-seat adjusting valve, sleeve adjusting valve, regulating butterfly valve, regulation ball valve, two-seater
Regulating valve etc..Sleeve adjusting valve is not suitable for the ore pulp class operating mode with particle.The valve plate of butterfly valve is easily washed away in runner.Ball
Ore pulp is easily deposited in valve sphere passage, easily scabs and blocks when being again turned on after parking cools down.And single-seat adjusting valve runner is into S-shaped,
Flow resistance is big and is not easily achieved more than DN300.And the operating mode pipeline of aluminum i ndustry is big, and medium is ore pulp, valve is washed away big and easy
Scab.And Y-shaped slurry regulating valve runner near linear, flow resistance are small, the precipitation that scabs is not easy.It is highly suitable for the ore pulp containing particle
Medium.But existing Y-shaped slurry regulating valve is since its valve aperture is bigger, flap weight weight, and because valve rod and runner are into 45
Angle is spent, easily causes valve rod flexural deformation, so as to cause flap misaligned with sealing surface of seat, causes interior leakage or closing forces to increase
Greatly.
Utility model content
The purpose of this utility model is to provide a kind of heavy caliber Y-shape sizing material valve with valve rod protection, existing at present to overcome
Technology above shortcomings, valve rod stress is smaller is not susceptible to deformation for its.
The purpose of this utility model is realized by following structure, it includes：Valve body, valve body connection valve deck, valve body
Valve seat and flap, flap connection valve rod are inside set, the flap top is equipped with inner sleeve, and the lower part of valve deck is equipped with outer sleeve, inner sleeve
Cylinder is stretched into outer sleeve, and inner sleeve can be slided with respect to outer sleeve.
The outer sleeve, inner sleeve are equipped with pressure release balance hole.
Pressure release balance hole is equipped with the outer sleeve and inner sleeve.
The length of the inner sleeve and outer sleeve adds up the flexible stroke more than valve rod.
Gap is equipped between the inner sleeve and outer sleeve.
The utility model plays the supporting role to valve rod, greatly by the outer sleeve and inner sleeve that are centered around outside valve rod
The big stress for reducing valve rod, makes valve rod be not easy flexural deformation, ensures that valve clack sealing surface and sealing surface of seat are concentric, when closed
Good sealing function is played, improves the service life of valve.
Brief description of the drawings
Fig. 1 is that figure is cutd open in the structural representation of the utility model, and Fig. 2 is the profile of flap, and Fig. 3 is the profile of valve deck.
Embodiment
The embodiment of the utility model includes as shown in Figure 1, Figure 2 and Figure 3：Valve body, valve body include left valve barrel 1 and right valve
Body 4, right valve barrel 4 connect valve deck 6, valve chamber are formed in left valve barrel 1, right valve barrel 4 and valve deck 6, to folder between left valve barrel 1 and right valve barrel 4
Connecting valve seat 2.Flap 3 coordinates with valve seat 2 carries out valve seal.Valve seat 2 and flap 3 are respectively positioned in valve chamber, and flap 3 connects valve rod
5.Connecting bracket 7 on valve deck 6, executing agency 8 is connected on stent 7.3 top of flap is equipped with inner sleeve 9, the lower part of valve deck 6
Equipped with outer sleeve 10, inner sleeve 9 is stretched into outer sleeve 10, and inner sleeve 9 can be slided with respect to outer sleeve 10.Outer sleeve 10 is equipped with and lets out
Balance hole 11 is pressed, enables the discharge out of it of the medium in infiltration inner sleeve 9 and outer sleeve 10, as medium can not be from 9 He of inner sleeve
Discharged in outer sleeve 10, just increase resistance when valve rod 5 stretches, and then the unlatching that valve will be influenced.The inner sleeve 9 and outer
The gap of 1-2mm is equipped between sleeve 10, easy to the slip between inner sleeve 9 and outer sleeve 10, reduces the resistance of valve opening and closing.It is described
The length of inner sleeve and outer sleeve adds up the flexible stroke more than valve rod.During the valve opening and closing of the utility model, inner sleeve
The telescopic slide in outer sleeve 10 of cylinder 9, plays the supporting role to valve rod 5, greatly reduces the stress of valve rod 5, to valve rod 5
Play protective effect.
To the described above of disclosed embodiment, those skilled in the art are enable to realize or use this reality
With new, a variety of modifications to present embodiment are it will be apparent that defined herein one to those skilled in the art
As principle can realize in other embodiments without departing from the spirit or scope of the present utility model.Therefore, it is all
Be with the same or similar technical solution of present embodiment, all fall within the scope of protection of the utility model.
