Abstract
The utility model provides a scale removal and two-sided sealing gate valve, which comprises an air cylinder, a valve plate and a valve body. The air cylinder is connected at one end of the valve body; the valve plate is arranged in the valve body; one end of the valve plate is connected with a piston rod in the air cylinder; an upper sealing ring and a lower sealing ring are arranged in the valve body; an elastic ring is respectively arranged between the upper sealing ring and the valve body and between the lower sealing ring and the valve body; a sealing washer is respectively arranged between the upper sealing ring and the valve plate and between the lower sealing ring and the valve plate. The utility model enables to scrape the dirt on the valve plate automatically in the opening and closing process, and allows to scrape the dirt on the valve plate to be clean in time, thus the damage of the dirt to a sealing part is avoided, the good sealing performance can be kept all the time, and the service life is prolonged. The utility model enables two-sided sealing, and can bear two-sided positive pressure and negative pressure (vacuum) action, and has wide applicability.
Description
Technical field
The utility model relates to the push-pull valve that is applicable to liquid and granular material emission control, belongs to the control valve technical field.
Background technique
Push-pull valve is widely used in fields such as the mud, ight soil discharging of chemical industry mucus material, city planting ductwork, is used for liquid and granular material emission control.Present push-pull valve is not all scraped the dirt function, after use a period of time, will produce dirt on the valve plate, and more and more thicker.It is all harder that some dirt resembles urine alkali, incrustation scale etc., is difficult to remove.Dirt on the valve plate also can stab wound the sealing surfaces that is in contact with it, and causes leakage, cisco unity malfunction.
Summary of the invention
The utility model provides a kind of scale removal dual face seals push-pull valve that remains excellent sealing performance, long service life at the deficiency that existing push-pull valve exists.
The utility model adopts following technical solution:
Scale removal dual face seals push-pull valve comprises cylinder, valve plate and valve body, cylinder is connected an end of valve body, be provided with valve plate in the valve body, piston rod in one end of valve plate and the cylinder is connected, upper sealing ring and lower sealing ring are installed in the valve body, elastic ring all is installed between upper sealing ring and lower sealing ring and the valve body, seal ring all is installed between upper sealing ring and lower sealing ring and the valve plate.
The piston rod of cylinder is connected with valve plate by T junction, directly drives valve plate with T junction and moves, and structure is compact more.
The operative end surface of upper sealing ring and lower sealing ring is to become 90 ° cutting edge with endoporus.
The common sealing pair of forming of the seal ring of valve plate, seal ring and seal ring end face, and in valve plate top and bottom formation dual face seals.When valve plate moved forward and backward, elastic ring can make upper sealing ring and lower sealing ring be adjacent to valve plate and strike off dirt on the valve plate, and seal ring can further be guaranteed the sealability of seal ring and valve plate.
The utility model can strike off the dirt on the valve plate automatically in the process of switch, the timely scraped clean of the dirt on the valve plate can have been avoided the infringement of dirt to sealed member, remains excellent sealing performance, has improved working life.And the utility model can be realized dual face seals, can bear two-sided malleation and negative pressure (vacuum) effect, and applicability is wide.

Embodiment
As shown in drawings, scale removal dual face seals push-pull valve of the present utility model comprises cylinder 1, valve plate 3, upper shell 9, lower shell body 4, upper sealing ring 11, lower sealing ring 6, following elastic ring 7 and last elastic ring 13.Upper shell 9 and lower shell body 4 are joined together to form valve body, are provided with seal ring 8 between upper shell 9 and the lower shell body 4, are provided with valve plate 3 between the two, and the piston rod in an end of valve plate 3 and the cylinder 1 is connected by T junction, and piston rod is provided with seal ring 2.The head of cylinder 1 inner piston rod is the T junction form, directly drives valve plate 3 with T junction and moves, and makes valve compact more.Cylinder 1 is connected an end of valve body.Upper sealing ring 11 is installed in the upper shell 9, between upper sealing ring 11 and the upper shell 9 elastic ring 13 is installed, the O-ring seals 10 that is embedded in the seal ring end face is installed between upper sealing ring 11 and the valve plate 3, the upper flange 12 that is connected with exterior line is installed on the upper-end surface of upper shell 9.Lower sealing ring 6 is installed in the lower shell body 4, between lower sealing ring 6 and the lower shell body 4 elastic ring 7 is installed, between lower shell body 4 and the valve plate 3 O-ring seals is installed also, the lower flange 5 that is connected with exterior line is installed on the lower end surface of lower shell body 4.
Upper sealing ring 11 and lower sealing ring 6 are adjacent to valve plate 3 respectively simultaneously under the elastic force effect of last elastic ring 13 and following elastic ring 7, guaranteed dual face seals.Upper sealing ring 11, lower sealing ring 6 and valve plate 3 all adopt hard material (pottery, quenching steel, glass etc.) to make, and upper sealing ring 11 and the operative end surface that lower sealing ring 6 contacts with valve plate 3 are made and are become 90 ° cutting edge with endoporus, when valve plate 3 when the piston rod of cylinder 1 promotes, the cutting edge of seal ring strikes off the dirt on valve plate 3 surfaces, to keep the bright and clean of valve plate 3 surfaces.This structure can guarantee dual face seals, can bear two-sided malleation and negative pressure (vacuum) effect, and applicability is extensive.O-ring seals is set in the seal ring section groove, is adjacent to the valve plate working surface in the course of the work, can guarantee sealability.
