Description
Technical field
The utility model relates to a kind of feeding valve, is specifically related to a kind of Pneumatic rotating feeding valve.
Background technique
Feeding valve is the valve that in Geldart-D particle, pump discharge pipeline in storehouse must be arranged, for the mass transport of storehouse pump in Geldart-D particle.In usual economizer Geldart-D particle, the discharge valve of storehouse pump adopts Pneumatic gate valve and water-cooled dome valve, material due to conveying is the granular material in economizer and denitration ash bucket, and temperature of charge is higher, is normally 350 ~ 450 DEG C, particle diameter is comparatively thick, has certain stickiness simultaneously.The feeding valve of storehouse pump adopts gate valve as the discharge valve on blow tank conveying pipeline, adopt between the spool of gate valve and valve body and firmly seal, in the switching process of feeding valve, spool is easily stuck by the material of the Large stone in valve pocket, causes the situation that valve event bite, switch are not in place, sealing surface damages.The seal ring of water-cooled dome valve can not bear the high temperature of 350 ~ 450 DEG C for a long time, and the cooling water passage of valve is as occurred wearing and tearing leakage simultaneously, brings fatal impact by giving the operation of economizer and denitration ash bucket ash-transmission system and grey storehouse.
Model utility content
For solving the problems of the technologies described above, the utility model provides a kind of Pneumatic rotating feeding valve, the highest design temperature of this valve reaches 450 DEG C, has the features such as wear resistance is strong, sealing is reliable, switch motion is fast, ensure that economizer and denitration ash bucket ash-transmission system run reliably.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of Pneumatic rotating feeding valve, comprise valve body and the spool being located at valve inner, described valve body upper end is provided with an execution cylinder, and the piston rod of this cylinder connects a connecting rod one, and this connecting rod one connects a rotating shaft and control described axis of rotation by this connecting rod one when cylinder operation; Described rotating shaft lower end has a connecting rod two, and this connecting rod two is connected with described spool by a hold down gag.
Preferably, described hold down gag is a compact heap, and this compact heap one end is fixedly connected with described connecting rod two, the other end is fixedly connected with described spool, and this compact heap inside is provided with a spring, and this spring keeps compressive state, connecting rod two described in the end thereof contacts of spring, the other end withstands described spool.
Preferably, described spool can rotate along with the rotation of connecting rod two.
This is for solving the problems of the technologies described above, the utility model provides a kind of Pneumatic rotating feeding valve, the Plane Rotation valve core structure of its uniqueness solves economizer and denitration ash bucket feeding valve in air-transport system at all and seals and anti abrasive problem, and the Spool rotating linkage mechanism of its uniqueness substantially increases the working life of pneumatic actuator simultaneously.The highest design temperature of this valve reaches 450 DEG C, has the features such as wear resistance is strong, sealing is reliable, switch motion is fast, ensure that economizer and denitration ash bucket ash-transmission system run reliably.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described.
Shown in Fig. 1 to 3, a kind of Pneumatic rotating feeding valve, comprise valve body 1 and the spool 2 being located at valve body 1 inside, described valve body 1 upper end is provided with an execution cylinder 4, the piston rod 3 of this cylinder 4 connects a connecting rod 1, and this connecting rod 1 is connected a rotating shaft 5 and rotated by the described rotating shaft 5 of this connecting rod 1 control when cylinder 4 works; Described rotating shaft 5 lower end has a connecting rod 27, and this connecting rod 27 is connected with described spool 2 by a hold down gag.
Preferably, described hold down gag is a compact heap 9, this compact heap 9 one end is fixedly connected with described connecting rod 27, the other end is fixedly connected with described spool 2, and this compact heap 9 inside is provided with a spring 8, this spring 8 keeps compressive state, connecting rod 27 described in the end thereof contacts of spring 8, and the other end withstands described spool 2.Spool 2 can rotate along with the rotation of connecting rod 27.
Working principle: as shown in Figures 1 to 3: valve body 1 and spool 2 have employed the high-quality tungsten alloy that existing certain degree of hardness has again certain toughness, so not only reached wear-resisting but also not easily fallen down by other objects of ash bucket and break up, secondly in the structure of valve body 1 and the motion mode of spool 2, being different from common ash disposal valve.The advanced working principle of valve is, during work, spool 2 is in the solid line position in Fig. 2, and material feeding mouth 10 is for open state; During closedown, cylinder 4 is rotated by connecting rod 1 drive shaft 5, rotating shaft 5 makes spool 2 transport 1/4 circle by connecting rod 27, spool 2 sealing surface is combined closely by the sealing surface of hold down gag and valve body 1, the elastic force of spring 8 makes spool 2 press to valve body 1 sealing surface all the time, and now material feeding mouth 10 is in closed condition, with reference to the dotted line position of spool 2 in Fig. 2, allow again spool 2 unrestricted motion above in the vertical direction simultaneously, contribute to compensating expanding with heat and contract with cold of valve body 1 itself.
Spool 2 produces rotation in valve body 1 tangent direction, produces self-grind, polishing, cleaning action (valve with from ash discharge function), keep very long sealing life to the sealing surfaces of valve body 1 and spool 2.In addition, when cylinder 4 operates, piston rod 3 does not stretch in valve body 1, can not produce the leakage ash phenomenon of other valves similar, reduce heat simultaneously and pass to cylinder 4, extend the life-span of pneumatic actuator.The highest design temperature of this valve reaches 450 DEG C, has the features such as wear resistance is strong, sealing is reliable, switch motion is fast, ensure that economizer and denitration ash bucket ash-transmission system run reliably.
To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.
