Abstract
The utility model discloses an inside exhaust knife gate valve, it is characterized in that a sealing seat and a supporting block are provided between the left and the right valve body plate, supporting rods are provided on both sides of the valve rod. Because of the design of the sealing seat and the supporting block between the left and the right valve body, and the supporting rods on both sides of the valve rod, the utility model improves the symmetricality of the valve plate and the rigidity of the valve plate and the valve rod so as to avoid the sealing seat being sheared, the force condition of the valve body is greatly improved, the knife gate valve has a small open-close torque, a long service life and an improved sealing effect so as to meet the needs of consumers.
Description
Technical field:
The utility model relates to the technical field of valve, specifically a kind of improved dark bar disconnecting link valve.
Background technique:
The disconnecting link valve is widely used in chemical industry, papermaking, the occasion that sewage treatment pipeline control media flows, be specially adapted to carry secretly silt, stone, wooden unit dams with the sewage conduct that contains fibre strip, though dark bar disconnecting link valve is because overcome the restricted problem of installing space of rising stem (RS.) disconnecting link valve, more and more be subjected to numerous clients' favor, but it is big that present of home make disconnecting link valve ubiquity open and close torque, nominal pressure is low, and because the off-centre of valve rod and flashboard, cause sealing seat to be cut pressure, and flashboard is subjected to the bending moment force effect, frictional force increases greatly, the valve opening and closing effort, valve rod is bent, and makes greatly reduce the working life of valve rod, and this has influenced the using scope of dark bar disconnecting link valve to a great extent.
Summary of the invention:
The purpose of this utility model is to provide a kind of improved dark bar disconnecting link valve, and it can improve the rigidity of valve rod, prolongs the working life of valve rod.
The technical solution of the utility model is achieved in that dark bar disconnecting link valve, it mainly comprises left and right valve body, be contained in the flashboard in the left and right valve body, the valve rod that is connected with flashboard, be provided with left and right side plate in the outside of valve rod, it is characterized in that: sealing seat and anchor plate are housed between left and right valve body, are provided with supporting rod in the both sides of valve rod.
The utility model is owing to be equipped with sealing seat and anchor plate between left and right valve body, both sides at valve rod are provided with supporting rod, strengthened flashboard to neutrality, improved the rigidity of flashboard and valve rod, thereby the phenomenon of having avoided sealing seat to be sheared is greatly improved the force-bearing situation of flashboard, it is little that this disconnecting link valve not only opens and closes moment, and long service life, improved sealing effect, satisfied user's demand.

Fig. 2 is the side view that has partial cutaway of Fig. 1
Fig. 3 is the sealing seat schematic representation among Fig. 1
Fig. 4 is the A-A sectional view of Fig. 3
Fig. 5 is the valve rod that matches with nut, supporting rod schematic representation among Fig. 1
Embodiment:
The utility model will be further described below in conjunction with drawings and Examples.
The utility model mainly comprises a left side, right valve barrel 9, be contained in a left side, flashboard 7 in the right valve barrel 9, the valve rod 5 that is connected with flashboard 7, outside at valve rod 5 is provided with a left side, right sideboard 3, it is different from prior art and is: on a left side, sealing seat 10 and anchor plate 8 are housed between the right valve barrel 9, be provided with supporting rod 4 in the both sides of valve rod 5, sealing seat 10 is provided with sealing guiding groove 11 in the enforcement, be provided with upper valve base 2 at upper end near valve rod 5, the link of one handwheel 1 is installed in the upper valve base 2 and with the threaded one end of valve rod 5 and is connected, sealing seat adopts tetrafluoroethylene to make, because the superior abrasion resistance and the self lubricity of polytetrafluoroethylmaterial material, greatly reduce the frictional force of flashboard and sealing seat, thereby reduced keying moment; Be provided with projection 12 at left valve barrel or right valve barrel during concrete enforcement, to guarantee the eccentric structure of gate valve, sealing seat 10 is contained in the lower end of left and right valve body 9, anchor plate 8 is contained in the middle upper end of left and right valve body 9, this anchor plate also adopts teflon to make, and matches with the pilot seal groove of sealing seat, strengthened flashboard to neutrality, improved the rigidity of flashboard, thus the phenomenon of having avoided sealing seat to be sheared; The end that present embodiment is located at the supporting rod 4 of valve rod both sides is threaded with upper valve base 2, the other end of supporting rod 4 and a left side, right valve barrel 9 is connected, supporting rod 4 passes nut 6, flashboard is placed on the bearing pin and is connected with valve rod with nut, strengthened the rigidity of valve rod, make the stressed of valve rod and nut be similar to axially, no longer be subjected to the influence of throw of eccentric, the force-bearing situation of flashboard is greatly improved simultaneously, eliminated the influence of the additional friction power that throw of eccentric brings, what the sealing guiding groove on the sealing seat made flashboard in addition mobilely has guidance quality, a leakage of having avoided flashboard to cause at stress down cut sealing seat.Rotate handwheel during use, drive valve rod by handwheel and rotate, nut moves up, and flashboard moves up with nut, and gate valve is opened, and as the handwheel counter-rotating, then flashboard moves down, and gate valve is closed.
