Abstract

The utility model relates to a special three-way valve for sludge which is used for direction switching of sewage and slurry fluid with mud-shaped impurities in industries of papermaking, sewage treatment, slurry delivery and the like. The special three-way valve comprises a T-shaped isometrical three-channel valve body, a ball core is mounted in the valve body from a side cover hole and is positioned at the center of the valve body, a guide sleeve is installed at the lower part of the ball core and is connected with a bottom shaft, a side cover and three channel ports of the valve body are provided with valve seats respectively, the valve seats are pretightened by adopting a disk spring, a seal surface is adhered to the ball core, an inner and outer double sealing ring is sealed with a channel inner hole of the valve body, the valve seats are tightly matched with the ball core, a valve rod is locked and installed in the valve body, one end of the valve rod is inserted into a groove with a shape corresponding to the section shape at the upper part of the ball core, and the other end of the valve rod extends out of the valve body, is fixedly connected with an output shaft of an actuating mechanism through a connecting sleeve and rotates with the actuating mechanism, so that a relative angle between the ball core and pipelines is changed to realize the flow direction switch of the three pipelines.

Description

Mud special three-way valve

Technical field:

The utility model relates to the mud special three-way valve that the direction of a kind of sewage that is used for industries such as papermaking, sewage treatment, slurry transportation, slurry class band earthy impurity fluid is switched.

Background technique:

At present, the direction switching of band earthy impurity fluid all adopts the mode of two deck valve door interlocks to realize, because reaction time, valve resistance, flowpath pressure and other various uncertain factors, two deck valve doors are switched can not be synchronous, pipeline produces vibrations, cause filtering equipment to have very big potential safety hazard, can't realize quick operation, thereby had a strong impact on manufacturing efficiency.

Summary of the invention:

The utility model provide an a kind of action can finish MEDIA FLOW to steady switching, thoroughly eliminated the mud special three-way valve that the pipeline that produces in the handoff procedure shakes the potential safety hazard of bringing to filtering equipment.

The utility model is achieved by the following technical solution: a kind of mud special three-way valve, its major technique feature is that described mud special three-way ball valve comprises the isometrical three runner valve bodies of T type, the ball core is packed into from the side cover hole in the valve body, place the valve body central position, guide sleeve is equipped with in the bottom of ball core, and be connected with lower shaft, at side cover and three runner mouths of valve body a valve seat is housed respectively, valve seat adopts the butterfly spring pretension, sealing surface is close to the ball core, in, the runner endoporus sealing of outer double seal ring and valve body, valve seat and ball core closely cooperate, and the valve rod lock is loaded in the valve body, one end is in inserting ball core top sectional shape with it in the corresponding groove, the other end stretches out valve body, and is fixedly connected on the actuator shaft by connecting sleeve, and rotates with actuator.

The utility model valve body adopts the isometrical three runners design of flange-type isoplanar T type, change ball core and pipeline relative angle and can realize the flow direction switching of three pipelines, fixed spheroid, the valve seat band seals with automatic pretension of butterfly spring and double density seal, the self-cleaning type sealing surface, spheroid and sealing surface of seat sprayed wc, and grind through purpose made technology, eliminate the stifled problem of earthy impurity card fully, effectively prevented the erosion of fluid.Complete machine has steady, the characteristics such as operational torque is little, long service life of switching.Owing to adopt the control of separate unit three-way valve, action can finish MEDIA FLOW to steady switching, thoroughly eliminated the pipeline that produces in the handoff procedure and shaken the potential safety hazard of bringing to filtering equipment, the operational efficiency of system increases more than 35% on year-on-year basis.

Description of drawings:

Fig. 1 is the structural representation of model utility.

Embodiment:

Among the figure, 1-flat gasket, 2-bolt, 3-lower shaft, 4-O shape circle, guide sleeve under the 5-, 6-ball core, 7-butterfly spring, the 8-packing ring, 9-outer seal ring, 10-valve seat, 11-inner seal ring, the 12-valve body, 13-valve rod, the last guide sleeve of 14-, 15-stud, the 16-flat gasket, 17-nut, 18-Packing seat, filler under the 19-, filler among the 20-, the last filler of 21-, 22-pressing plate, 23-side cover.

As shown in Figure 1, this mud special three-way valve, comprise the isometrical three runner valve bodies 12 of T type, ball core 6 is packed into from side cover 23 holes in the valve body, place the valve body central position, guide sleeve 5 is equipped with in the bottom of ball core, 14, and be connected with lower shaft, at side cover and three valve flowing channel mouths a valve seat 10 is housed respectively, valve seat adopts butterfly spring 7 pretensions, and sealing surface is close to the ball core, in, outer double-sealing 11,9 rings seal with the runner endoporus of valve body, valve seat and ball core closely cooperate, and valve rod 13 lock is loaded in the valve body, and an end is in inserting ball core top sectional shape with it in the corresponding groove, the other end stretches out valve body, and be fixedly connected on the actuator shaft by connecting sleeve, and rotate with actuator, can realize the flow direction switching of three pipelines to change ball core and pipeline relative angle.
