Definitions

  • the present invention relates to a valve. Background technique
  • valves the seal at the valve stem is usually sealed with a gasket ⁇ or packed with packing.
  • the disadvantage of this type of seal is that the valve stem moves up and down in the gasket or packing, causing the gasket or packing to be worn, the medium is easy to leak out, and the valve stem is easily corroded and rusted by the medium.
  • Such valves are laborious, have a short life, have unreliable seals, and are inconvenient to maintain.
  • the object of the present invention is to provide a valve which is flexible in switching, does not leak, has high sealing reliability, long life, convenient maintenance, simple structure, and low cost.
  • valve which has a valve body, a valve cover, a valve core, a seal, and a valve actuator.
  • the valve core has a valve core head, which is characterized in that the seal is a Seal ⁇ , it has a bottom Zhenghe edge tightly sleeved on the valve core head;> A slot is formed between the valve cover and the valve body, the edge is inserted into this slot to be sandwiched between the valve cover and Between the valve bodies; the valve cover and the valve body are connected so that the edge is tightly pressed between the valve body and the valve body so that the seal ⁇ separates the valve core from the fluid medium.
  • FIG. 1 is a cross-sectional view of a specific embodiment of a valve of the present invention. Best Mode of the Invention
  • the valve has a valve body 1, a round hole-shaped valve seat 2 located inside the valve body 1, a valve core with a spool head 4 and a spool tail 7, and a seal with a bottom 3 and an edge 6 ⁇ , threaded post 8, bonnet 9 and handle 10.
  • Seal base 3 is used to make contact with seat 2 during sealing.
  • the seal is made of an elastomeric material, in particular an elastic rubber.
  • the seal cymbal also has a corrugated tubular, cylindrical, or lip-shaped body part 5 located between the cymbal bottom 3 and the edge 6.
  • the trunk 5 should be easily deformed elastically.
  • the bottom 3 is tightly wrapped around the spool head 4.
  • valve cover 9 and the valve body 1 are detachably fixedly connected, and a groove is formed between the valve cover and the valve body, especially an annular groove.
  • the convex edge 6 at the upper end of the trunk 5 is inserted into this groove.
  • the valve cover 9 and the valve body 1 should be connected so that the above edge is tightly pressed between the valve body and the valve cover, so that the seal ⁇ separates the valve core from the fluid medium.
  • the spool end 7 is a cylinder with a central hole.
  • the outer surface of the cylinder is provided with two or more anti-rotation convex ribs arranged at substantially equal intervals in the circumferential direction.
  • the surface of the central hole is provided with a threaded structure.
  • the cap 9 is in the shape of a bottomless bottle, and the inner surface of the neck portion is provided with two or more grooves corresponding to the convex edges on the outer surface of the spool 7.
  • the spool end fits into the neck of the bonnet and moves axially around the neck.
  • the outer surface of the threaded post 8 is provided with a thread, and the thread is matched with the thread on the surface of the central hole of the spool 7.
  • the top of the bonnet 9 is provided with a round hole.
  • the threaded post 8 has a small shaft protruding at its upper end, and the small shaft just extends out of the round hole on the top of the valve cover 9 and is fixedly connected to the handle 10.
  • the threaded post 8 has an annular protrusion at a position adjacent to the upper end portion, and the annular protrusion cannot pass through a circular hole at the top of the valve cover, so that the screw post 8 is axially positioned relative to the valve cover 8.
  • the spool tail 7, the threaded post 8, the bonnet 9 and the handle 10 together form a spiral Advancing mechanism.
  • the bottom 3 will move up and down with the spool head 4 to open and close the valve.
  • the present invention may also have other structural modifications without departing from the scope of the present invention.
  • the Gang core head may be conical or other suitable shapes; the seal may also be other suitable shapes.

Abstract

L'invention porte sur une soupape pour tuyau de gaz ou de fluide comprenant un corps de soupape, un bouchon de soupape, un élément de soupape à section de tête, un élément d'étanchéité et un actionneur, l'élément d'étanchéité étant un soufflet dont la partie inférieure (3) est insérée dans la section de tête (4) de l'élément valve. Un côté (6) du soufflet vient entre le corps de soupape et le bouchon de soupape de manière à rendre la soupape hermétique. L'invention fait preuve d'une bonne étanchéité, d'une longue durée de vie, d'une structure simple et d'un coût faible.
