Abstract
A full-closed bidirectionally sealed plug-in plate valve is composed of a valve body with pressure meter and N2 inlet, oblique or parallel front and back valve plates, an end cover of valve body, a cylinder unit between said valve plates and with push rod linked to said front and back valve plates, two pneumatic sealing rings for said valve plates, and a reverse valve in the internal hole of said push rod and connected to an external control cylinder.
Description
Technical field
The present invention relates to the push-pull valve technical field, particularly a kind of full closed two-way seal insert plate valve.
Background technique
Push-pull valve is a kind of valve of having many uses.More or less there are some problems in employed various push-pull valves at present, mainly are that sealing effect is not ideal enough; Volume is too huge; Maintenance is inconvenient, need dismantle whole valve when changing seal ring, influences usage ratio of equipment; Working state to valve does not have the observation of sight to understand; Can not in time clean valve inner etc.Trace it to its cause, the structure that is exactly valve is reasonable inadequately, and seal approach is thorough inadequately, and control device is perfect inadequately.Utility model patent 02218950.5 high-performance push-pull valve, its valve component is made up of front valve shell, rear valve body and middle valve body, and the corresponding surface of middle valve body and front valve shell is provided with the ripple expansion bend, and dual water cooling plant is housed on valve board assembly and the valve seat.It is complicated, bulky that the structure of this push-pull valve seems, is of limited application.
Summary of the invention
The purpose of this invention is to provide a kind of rational in infrastructurely, good sealing effect is controlled flexiblely, is easy to the full closed two-way seal insert plate valve of safeguarding and overhauling.
The objective of the invention is to realize by following technical proposals.
According to full closed two-way seal insert plate valve of the present invention, comprise valve body, preceding valve plate, back valve plate, valve body end cap, it is characterized in that being provided with in the cavity between the valve plate in described valve body a cylinder mechanism, the piston rod of this cylinder mechanism is connected with preceding valve plate, back valve plate by link, the two ends of preceding valve plate, back valve plate are provided with pneumostop chamber circle, the push rod endoporus of cylinder mechanism connects a selector valve, this selector valve is communicated with pneumostop chamber circle, and described cylinder mechanism is connected on the cylinder base.
The anterior selector valve of the push rod of described cylinder mechanism connects the outer control cylinder of a valve body.
Be provided with a pressure gauge on described valve body top.
Downside at described valve body upper pressure table is provided with a nitrogen inlet.
Be provided with motor-variable-speed motor at described valve body middle part, the output shaft of this variable-speed motor passes valve body, the affixed gear in termination at the output shaft of this variable-speed motor, this gear is meshed with a toothed rack, this tooth bar contacts by a pair of upper saw pulley and the motion of valve interior wall do and is connected with valve plate, thereby constitutes the valve plate driving mechanism.
Described valve plate driving mechanism is for being located at two cover mechanisms of valve body both sides symmetrically.
Valve plate or back valve plate tilt before described, and perhaps preceding valve plate, back valve plate all tilt.
Valve plate, back valve plate are parallel to each other before described.
Described cylinder base is connected on the valve body end cap by bolt.
Pneumostop chamber, the two ends circle of valve plate, back valve plate all exceeds valve plate surface 2-4mm before described.
Advantage of the present invention is:
1, owing to adopted in the cavity between the valve plate in valve body cylinder mechanism is set, thereby has dwindled the volume of valve, shortened stroke.
2, owing to adopted the pneumostop chamber circle at preceding valve plate, valve plate two ends, back, under the effect of gas pressure, strengthened sealing effect.And gas do not have wearing and tearing actions to seal ring, makes seal durability long.
3, because pneumostop chamber, the two ends circle of preceding valve plate, back valve plate all exceeds valve plate surface 2-4mm, under the situation that source of the gas breaks down, the inclined-plane of this 2-4mm still can play seal action.
4, owing to be provided with pressure gauge, can detect the variation in pressure in the valve body, understand the working state of valve, have or not leakage.In case increased pressure illustrates to have produced leakage phenomenon, should dispose accordingly.
5, owing to be provided with nitrogen inlet, available nitrogen cleans the dust on the valve body inner sealing surface, thereby improves sealing effect, prolongs seal durability.
6, because the cylinder base is connected on the valve body end cap by bolt,, pull out two valve plates as long as therefore when maintenance, pull down the cylinder base, can overhaul.
