Abstract
A sealable self-adjusting type flashboard valve comprises a valve body, an upper cover plate arranged at the top of the valve body, a lower cover plate arranged at the bottom of the valve body, a connecting channel formed in the upper cover plate and the lower cover plate in an upper-and-down corresponding manner, a valve plate horizontally arranged in the valve body and a valve rod, wherein a seal ring arranged at an upper opening of the connecting channel is connected to the upper cover plate; the lower end face of the seal ring is in sealed contact with the upper surface of the valve plate; a discharge pipe section arranged at a lower opening of the connecting channel is connected with the lower cover plate; a valve rod seal assembly is arranged between the valve rod and the valve body; slides parallel to the movement direction of the valve plate is arranged in the valve body; the valve plate is connected to the slides in a sliding manner; and self-adjusting seal assemblies for pulling the two slides upwardly to enable the upper surface of the valve plate and the seal ring to always maintain seal and to be matched with each other in a sliding manner are arranged on the upper cover plate. The sealable self-adjusting type flashboard valve provided by the utility model is reasonable in design, simple in structure, strong in practicability and easy to realize popularization and application, can realize automatic adjustment of the tightness of the valve plate, saves the cost for replacing the seal ring and/or the valve plate, and fully prolongs the service life of the flashboard valve.
Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of sealing self-interacting type push-pull valve.
Background technique
Sealing contacts the valve plate upper and lower surface of existing push-pull valve with lower cover plate with seal ring respectively, in use, because the frequent folding of valve plate causes the friction with seal ring, lower cover plate, in the course of time, the valve plate upper and lower surface just has the gap respectively and between the seal ring, lower cover plate, poorly sealed, as to cause medium to be revealed problem.This just needs to change seal ring and/or valve plate, and it is big not only to change difficulty, and the cost height.In addition, the patent No. is that ZL201220141922.0 discloses a kind of push-pull valve, it can manual tune valve plate upper and lower surface be in the sealing contact condition with seal ring and lower cover plate respectively, owing to can not regulate automatically, in use, just find behind dielectric leakage, take manual tune then, this regulative mode has hysteresis quality and the situation that causes medium still can occur revealing.
The model utility content
The utility model provides a kind of sealing self-interacting type push-pull valve in order to solve deficiency of the prior art.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: sealing self-interacting type push-pull valve, comprise valve body, the upper cover plate that the valve body top arranges, the lower cover plate that the valve body bottom arranges, upper cover plate and lower cover plate be the corresponding connecting passage that arranges up and down, the horizontally disposed valve rod that stretches out valve body that is connected for the valve plate that opens and closes connecting passage and with valve plate in the valve body, connecting passage place suitable for reading is provided with the seal ring that is connected with upper cover plate, the seal ring lower end surface contacts with the sealing of valve plate upper surface, connecting passage end opening place is provided with the object-discharging pipe joint that is connected with lower cover plate, be provided with valve rod sealing assembly between valve rod and the valve body, be provided with the slideway parallel with valve plate moving direction in the valve body, valve plate is slidingly connected on the slideway, described upper cover plate is provided with for upwards spurring the black box of debugging certainly that two slideways make valve plate upper surface and seal ring remain sealing and be slidingly matched, and debugs black box certainly and is provided with at least two covers.
Black box includes screw rod, nut, goes up pressure pad described every cover from debugging, sleeve pipe, pressure pad and compression spring down, screw rod is upward through slideway and upper cover plate by the slideway bottom, sleeve pipe, following pressure pad, compression spring and last pressure pad are located on the screw rod from bottom to top successively, be provided with stuffing box packing in the toroidal cavity that forms between sleeve pipe, upper cover plate and the following pressure pad, nut thread is connected on the screw rod and makes the compression spring between following pressure pad and last pressure pad be in compressive state.
Adopt technique scheme, remain power upwards owing to spur two slideways from the elastic force of debugging black box employing compression spring by screw rod, thereby guarantee that the valve plate upper surface keeps good sealed sliding movingly with seal ring always, thus solve push-pull valve long between in use after the poorly sealed problem that dielectric leakage occurs.The effect in the gap between sealing screw rod and the upper cover plate is played in stuffing box packing.
The utility model is reasonable in design, simple in structure, realizes the sealing of automation adjusting valve plate, has saved the cost of changing seal ring and/or valve plate, has fully prolonged the working life of push-pull valve, and is practical, is easy to apply.
