Abstract
The invention relates to a valve buffering structure, which is characterized in that a valve clack is provided with a central through hole and a bypass hole communicated with the central through hole, a sealing assembly is arranged between the central through hole and the bypass hole, a sealing flap of the sealing assembly is connected with a transmission rod, and a limiting mechanism is arranged between the transmission rod and the valve clack. The method is characterized in that: through set up buffer structure on the valve clack of valve, reduced valve business turn over end pressure differential, realize pressure balance, alleviate the medium greatly to the impact of valve element, the valve is opened the operation steadily, and the vibration amplitude is little, and the noise is low, the life of extension part.
Description
Technical field
The present invention relates to a kind of valve, particularly can regulating valve import and the valve buffer structure that exports pressure reduction.
Background technique
Valve is to lean on the cooperation of valve body and flap to control fed sheet of a media, and behind the valve closing, its entrance point is different with the pressure of outlet end; Produce pressure reduction; In the moment of valve opening, when the existence of pressure reduction can cause medium to pass through valve, valve part and pipeline are produced huge instant impact; Cause the valve vibrations, and produce with noise.Vibrations exert an influence to sealability, working life and other equipment that is used to detect of valve and coupled pipeline.Particularly be applied to the valve on the high-pressure duct system, its vibrations are particularly violent.Under some specific high pressure operating modes, existing valve can not satisfy smooth operation, vibration amplitude is little, noise is low requirement.
Summary of the invention
The object of the present invention is to provide a kind of valve buffer structure,, realize reducing vibrations and noise, guarantee the valve usability through regulating valve inlet/outlet pressure.
Technical solution of the present invention is: a kind of valve buffer structure; It is characterized in that the by-pass hole that on flap, is provided with central through bore and communicates with central through bore; Between central through bore and the by-pass hole black box is set; The sealing lobe of black box is connected with drive link, is provided with position-limit mechanism between drive link and the flap.
Described position-limit mechanism is on the flap wall, to offer through hole, and restraining groove is established in position relative with through hole on the drive link, and spacing ball is positioned at through hole and restraining groove, is provided with the stop screw that the restriction spacing ball moves in the through hole.
Valve buffer structure provided by the invention is on the flap of valve, to offer central through bore and at least 2 symmetrically arranged by-pass holes, and central through bore communicates with by-pass hole, can the import of valve be communicated with outlet.Be provided with black box between central through bore and the by-pass hole, be used for its connection or disconnection.The sealing lobe of black box is connected with drive link, between drive link and the flap position-limit mechanism is set, and limits the scope that drive link moves along the flap central through bore through position-limit mechanism.When drive link moves, at first drive the sealing lobe and move, drive flap then and move; Like this, in the valve opening process, there is the part medium to enter into outlet end from the valve inlet end earlier through central through bore and by-pass hole; With compensation flap import and outlet end pressure; Reduce pressure reduction, reduce the impact of medium to valve element, valve just can all be opened afterwards.
Characteristics of the present invention are: through on the flap of valve, buffer structure being set, reduced valve entrance end pressure reduction, realized pressure balance; Alleviate the impact of medium greatly to valve element, the valve opening smooth operation, vibration amplitude is little; Noise is low, prolongs the working life of parts.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is described further:
As shown in the figure, the valve buffer structure be with flap 1 that valve body 13 matches on offer central through bore 2 and 2 symmetrically arranged by-pass holes 3 of perforation, be not limited to 2, by-pass hole is connected with central through bore.Central through bore section from the flap seal face to by-pass hole is provided with sealing seat 4, and sealing seat is provided with sealing lobe 5, constitutes black box.When black box was in closed condition, by-pass hole was not communicated with the central through bore of bottom, and when black box was in opening state, by-pass hole was communicated with the central through bore of bottom, and the import of valve is connected with outlet end.The sealing lobe is connected with drive link 6 one ends, and the drive link the other end stretches out outside the central through bore and is connected with driving mechanism.Position-limit mechanism is on the perisporium on flap top, to be distributed with through hole 7; Generally can be symmetrical set 4 through holes; The drive link relative with through hole is provided with annular spacing groove 8, and spacing ball 9 is positioned at through hole and restraining groove, and be through the stop screw 10 that is connected with through hole whorl that spacing ball is spacing; The height of restraining groove is the distance that the sealing lobe moves in the flap central through bore, the central through bore with the flap bottom after should satisfying black box and opening is communicated with by-pass hole.
During Open valve; Drive underdrive bar at driving mechanism rises; Connected sealing lobe rises thereupon, and this moment, flap was motionless, and black box is opened earlier; Medium will enter into outlet end 12 from valve inlet end 11 through central through bore and by-pass hole, come the pressure of compensation flap entrance end through the medium of a small amount of inflow.Along with drive link continues to rise, under the restriction of position-limit mechanism, sealing lobe and flap move valve opening simultaneously.Otherwise drive link moves down, and closes black box earlier, along with drive link continue move down valve closing.
Claims (2)
1. valve buffer structure; It is characterized in that the by-pass hole that on flap, is provided with central through bore and communicates with central through bore; Between central through bore and the by-pass hole black box is set, the sealing lobe of black box is connected with drive link, is provided with position-limit mechanism between drive link and the flap.
2. valve buffer structure according to claim 1; It is characterized in that described position-limit mechanism is on the flap wall, to offer through hole; Restraining groove is established in position relative with through hole on the drive link, and spacing ball is positioned at through hole and restraining groove, is provided with the stop screw that the restriction spacing ball moves in the through hole.
