Abstract
The utility model discloses a valve clack and valve rod installing structure which has high sealing stability and is easy to assemble and disassemble. The valve clack and valve rod installing structure is characterized in that the other side of a valve clack cover is lengthened so as to form a reinforced guide sleeve which is matched with a valve rod. The reinforced guide sleeve additionally arranged in the valve clack and valve rod installing structure can be used for ensuring the tight matching of the valve clack cover and the valve rod, so that the valve clack and valve rod installing structure has very good valve clack guide property, when a valve is arranged at each angle, the stability of the valve clack is ensured, and the valve clack can be always aligned at the sealing surface of the valve body. The valve clack and valve rod installing structure has the advantages of improving the sealing stability of the valve body and being convenient to assemble and disassemble and is prolonged in service life.
Description
Technical field
The utility model relates to a kind of valve, and more particularly, it relates to the mounting structure of a kind of flap and valve rod.
Background technique
Current flap and the mounting structure of valve rod are by flap, valve clack cover and valve rod form, valve rod inserts in the cavity of flap, and use the valve clack cover limiting locking, valve clack cover is connected with flap spot welding, in use find, the mounting structure of flap and valve rod can be offset by flap after using a period of time, loosening, make the valve seal hydraulic performance decline, because valve adopts the conical surface seal mode, Percent of contact area to sealing surface is had relatively high expectations, the tradition valve clack cover is too short, steering capability is poor, can't guarantee the sealing stability of valve body, and flap and valve clack cover is soldered connects, inconvenient disassembling, assembling and replacing, had a strong impact on working life.
The model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide and aims to provide a kind of flap that has high sealing stability and easily assemble and dismantle and the mounting structure of valve rod.
For achieving the above object, the utility model provides following technological scheme: the mounting structure of a kind of flap and valve rod, comprise flap, valve clack cover, valve rod, described valve clack cover is provided with the transitional pore suitable with valve rod, described valve rod lower end is provided with convex shoulder, described flap upper end is provided with cavity, described cavity and convex shoulder radial cross section are suitable, described convex shoulder is placed in cavity, described valve clack cover is placed on valve rod by transitional pore, and be fixedly connected with flap, described valve clack cover one side is provided with limiting stopper, described limiting stopper inserts in cavity, limiting stopper end and convex shoulder upper end are inconsistent, described valve clack cover opposite side extends, form and strengthen guide sleeve, described reinforcement guide sleeve and valve rod are suitable.
By adopting technique scheme, the reinforcement guide sleeve that the mounting structure of this flap and valve rod increases, can closely cooperate with valve rod, make it have better flap steering capability, guarantee the stability of valve flap when each angle is installed, can align all the time valve body sealing surface, improve valve seal stability.
Limiting stopper on described valve clack cover is shaped as cylindrical, is integrally formed the formula sleeve with the reinforcement stop collar.
By adopting technique scheme, this integral type sleeve design has improved the coaxality of valve clack cover, has not only guaranteed the stability of the mounting structure guiding of flap and valve rod, and has reduced manufacturing procedure, has reduced cost of production.
Described valve clack cover is connected with positioning screwn with flap.
By adopting technique scheme, this flap is compared the existing mode that is fixedly connected with the mode that the mounting structure of valve rod adopts screw to be connected, and it has advantages of convenient for assembly and dismounting, has extended working life simultaneously.
The accompanying drawing explanation
The mounting structure embodiment's of Fig. 1 the utility model flap and valve rod structure sectional view.
Reference character: 1, flap; 11, cavity; 2, valve clack cover; 21, transitional pore; 22, strengthen guide sleeve; 23, limiting stopper; 3 valve rods; 31, convex shoulder; 4, positioning screwn.
Embodiment
With reference to Fig. 1, the mounting structure embodiment of this practical flap and valve rod is described further.
The mounting structure of a kind of flap and valve rod, comprise flap 1, valve clack cover 2, valve rod 3, described valve clack cover 2 is provided with the transitional pore 21 suitable with valve rod 3, described valve rod 3 one ends are provided with convex shoulder 31, described flap 1 upper end is provided with cavity 11, described cavity 11 is suitable with convex shoulder 31, described convex shoulder 31 is placed in cavity 11, described valve clack cover 2 is placed on valve rod 3 by transitional pore 21, and be fixedly connected with flap 1, described valve clack cover 2 one sides are provided with limiting stopper 23, described limiting stopper 23 and cavity 11 screw-thread fit, limiting stopper 23 ends and convex shoulder 31 upper ends are inconsistent, described valve clack cover 23 opposite sides extend, form and strengthen guide sleeve 22, described reinforcement guide sleeve 22 is suitable with valve rod 3.Strengthening guide sleeve 22 can make valve clack cover 2 tightr with valve rod 3 combinations, make the mounting structure of this flap and valve rod have better flap 1 leading role, guarantee the stability of valve flap 1 when each angle is installed, can align all the time valve body sealing surface, improve the sealing stability of valve body 11, postponed working life.
Limiting stopper 23 on described valve clack cover 2 is shaped as cylindrical, is integrally formed the formula sleeve with reinforcement guide sleeve 22.The integral type sleeve design has improved the coaxality of valve clack cover 2, has not only guaranteed the stability of the mounting structure guiding of flap and valve rod, and has reduced manufacturing procedure, has reduced cost of production.
Described valve clack cover 2 is connected with flap 1 use positioning screwn 4.The mode that adopts screw to connect is compared the existing mode that is fixedly connected with, and it has advantages of convenient for assembly and dismounting, has extended working life simultaneously.
The present embodiment is when work, the convex shoulder 31 of valve rod 3 inserts in cavity 11, valve clack cover 2 entangles valve rod 3 by transitional pore 21, it is inconsistent with convex shoulder 31 upper ends that its front limit piece 23 enters cavity 11, with positioning screwn 4, that valve clack cover 2 is fixing with flap 1 again, the reinforcement guide sleeve 22 on valve clack cover 2 tops can strengthen the combination with valve rod, make the mounting structure of this flap and valve rod have better steering capability, and valve clack cover 2 is compared existing spot welding with the mode that flap 1 adopts screw to be connected and is connected, it has advantages of convenient for assembly and dismounting, has extended working life simultaneously.
