Description
Technical Field
The utility model belongs to the technical field of the sealing of valve, especially, relate to a antiseep seals up combined mechanism.
Background
The sealing form of the switch equipment such as a valve in the market at present basically adopts hard contact type sealing, namely the sealing form of direct contact between a valve rod and a valve seat, because a conveying medium contains impurities such as silt and the like, the sealing surface is abraded after being continuously opened and closed for several times, the sealing surface is not tightly closed after being damaged, the sealing is not tightly sealed and leakage occurs, the whole set of equipment needs to be replaced to cause resource waste such as manpower and material resources, the normal production is influenced, and the maintenance is difficult and long.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem that the background art exists, the utility model aims at providing a antiseep seals up combined mechanism, this seal structure's sealing washer bad after directly change the sealing washer can, easy operation need not the whole set of valve of whole change.
The utility model provides a technical problem adopt following technical scheme to realize: this antiseep seals up combined mechanism, including the valve body, a set of sealing washer B is installed to a set of annular groove of valve body inner wall, and the circular bead joint of valve body lower extreme has the valve clack, and the lower extreme of valve clack and the circular bead joint of disk seat, the valve rod has been cup jointed to the inner chamber of valve body, valve clack and disk seat, installs sealing washer C on the lower part of valve rod and the face that the disk seat corresponds, and the valve rod lower extreme is equipped with three U-shaped breach along week, forms the boss between two adjacent U-shaped breachs.
In the scheme, the outer wall of the valve body is provided with the sealing ring A, and the lower end surface of the valve seat is provided with the sealing ring D.
The utility model has the advantages that:
the utility model discloses a precision fit between nitrile rubber circle and the disk seat plays sealed effect. When the sealing mechanism is opened, the valve rod sealing ring is screwed out of the valve seat along the axial direction through the rotary valve rod, liquid flows to the Z direction from the P direction, when the sealing mechanism is closed, the valve rod is screwed into the P direction through the screw rod, the rubber ring is moved into the valve seat, the P direction is sealed, the liquid flows to the Z direction from the liquid, the axial sealing ring is used for sealing, when the sealing ring moves along the axial direction, the precision fit and the elasticity of the sealing ring between the sealing ring and the valve group are used, sundries in a medium can be pushed out along the flow direction of the medium, the sealing surface can be guaranteed not to be damaged easily, and the sealing performance of the anti-leakage sealing combination mechanism can be guaranteed. The cost of having practiced thrift very much of this application, easy operation, extension equipment life need not training and special equipment, and the equipment maintenance point is single, need not to change essential element when sealed not tight, only need to change the rubber circle can. The problem that the existing equipment is not tightly sealed after being opened and closed for many times and affects the process production is solved, the production capacity is improved, the maintenance period is shortened, and the maintenance cost is reduced.
