Abstract
The utility model relates to a slurry knife gate valve, which comprises a valve body 1, a valve cap 2, a knife switch 3, a valve handle 5, a bracket 4 and a hand wheel 7. The utility model has the technical proposal that a rubber lining 8 is fixed in the inner cavity of the valve body. A flushing and discharging hole 10, the outer end of which is connected with a water flushing and discharging pipe by a breaking gate 9 is arranged on the lower end of the knife switch corresponding to the valve body 1. The valve body of the gate valve has excellent corrosion resistance and abrasion resistance. The gate valve is provided with the device flushing and discharging the sediment and can guarantee the knife gate can be completely pushed to guarantee the sealing performance of the knife switch 3.
Description
The utility model belongs to a kind of FLUID TRANSPORTATION that is used for, and particularly the gate valve of adjusting usefulness is carried and flowed to slurry.
At present, producing the disconnecting link valve that uses mainly is made up of valve body, valve gap, disconnecting link, support, valve rod, handwheel.The inner chamber of this disconnecting link valve is the internal surface of metal valve body, is generally cast iron or Cast Steel.In the slurry course of conveying, because the solid particle that contains in the body is more, and some slurries contain more corrosive material.Wearing and tearing and corrosion to valve body are all compared seriously, and it can seriously reduce the usability and the working life of disconnecting link valve.Moreover this disconnecting link valve, in order to improve the sealability of its disconnecting link, on the pairing body cavity of disconnecting link, be processed with a groove, because contained solid particle deposits in the groove of body cavity lower end easily in the slurry, this groove is silted up, so just seriously influenced the performance of closing of disconnecting link, disconnecting link can not be closed well.Because this gate valve is connected among the pipeline, the shoal materials in the groove is difficult to remove.
The purpose of this utility model is in order to overcome above-mentioned deficiency, and a kind of valve body wear-resisting property and the corrosion resistance that provide are better, the disconnecting link valve that the sediments in the valve pocket groove is convenient to clear up.
The utility model is to realize like this, it comprises the valve body that constitutes the conventional knives gate valve, valve gap, disconnecting link, support, valve rod, handwheel etc., for wear resistance and the antiseptic property that strengthens body cavity, fixed installation one deck rubber lining in body cavity, in case contacting of the fluid that is transferred and body cavity metal covering reaches anticorrosion, the wear-resisting purpose of body cavity.For the ease of removing the sediments in the pairing body cavity groove of disconnecting link, on the pairing bottom valve body of disconnecting link, establish one towards discharge orifice, should towards discharge orifice through a pipe valve be connected towards waste pipe.Like this, when in the groove in the body cavity sediments being arranged, can open the pipe valve below discharge orifice, sediments is discharged, if the sediments in the groove can not be discharged or can not emptying the time, can be injected with the pressure clear water towards discharge orifice to body cavity by this, the sediments in the groove is dashed, make it to be flushed in the body cavity or and emit again it.
Because this body cavity is installed with the rubber lining, makes this disconnecting link valve have Corrosion Protection and wear-resisting property preferably.This disconnecting link opens and closes between rubber sleeve, is two-way soft seal, flexible operation, and long-time running is safe and reliable.Moreover install one bottom towards tapping equipment at this valve body of disconnecting link correspondence, be used for the material of the row's of dashing deposition, ensure disconnecting link can lock on earth, earial drainage does not so just guarantee the sealability of disconnecting link effectively.
Fig. 1 is a structure principle chart of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Below in conjunction with accompanying drawing the utility model is described in detail.
Valve body 1 of the present utility model, valve gap 2, disconnecting link 3, support 4, valve rod 5, handwheel 7 all adopt structural type traditionally, the two ends that are valve body 1 have mounting flange, support 4 is fixed on the upper end of valve gap 2, valve gap 2 is fixedly mounted on the upper end of valve body 1, be installed with one in the upper end of disconnecting link 2 and be threaded valve rod 5, be equipped with in the upper end of valve rod 5 and the handwheel 7 of valve rod 5 to be threaded.In order to strengthen the anticorrosion and wear-resisting property of valve body 1 inner chamber, in the inner chamber of valve body 1, be installed with rubber lining 8, this rubber lining 8 preferably adopts has detachable, interchangeable standard piece, so not only is convenient to maintenance, and can improves valve complete machine 3-4 in working life doubly.In order to wash away the material of deposition, establish one bottom towards discharge orifice 10 at the valve body 1 of disconnecting link 3 correspondences, towards discharge orifice 10 can be vertical hole, also can be " L " shape hole or " ⊥ " shape hole, so that pipe valve 9 is installed and is discharged water pipe and be connected and be as the criterion with dashing through pipe valve 9.For the ease of the discharge of deposition material with to the flushing of valve body 1 lumen channels bottom, preferably be processed into " V " font structure towards the upper end portion of discharge orifice 10.In order to find out the aperture of this disconnecting link valve intuitively, regulate flow exactly, on valve rod 5, fix a pointer 11, reading board 12 of fixed installation on support 4.So just can be provided with, during disconnecting link 3 contract fullys, 0 position on the pointer 11 corresponding reading boards 12 is that a scale unit marks on reading board 12 for 1 millimeter or 1 centimetre with disconnecting link 3 every risings.In order to ensure production safety, between handwheel 7 and support 4 locking framework 6 is installed, locking framework 6 can be that a bearing pin is installed on handwheel 7, establishes a pin-and-hole on support 4, by cooperating between this bearing pin and the pin-and-hole, they lock together and get final product lock handle with one again.Also can be that a spring pin is set on handwheel 7, cooperate formation by this spring pin with pin-and-hole on the support 4, can also be all to establish pin-and-hole on handwheel 7 and the support 4, handwheel 7 and support 4 locked together through two pin-and-holes with padlock.
