Abstract
The utility model relates to a gate valve, comprising a valve cover, a gland box, and a valve rod; wherein, the valve rod is arranged in the valve cover and the gland box, the gland box is provided with a supporting ring therein; the supporting ring is fixedly connected with the valve cover; and the supporting ring is welded on the valve cover. According to the gate valve of the utility model, when the valve cover or the gland box is damaged, an operator only needs to separate the supporting ring from the valve cover to replace the component, after the new component is replaced, the supporting ring and the valve cover are assembled together again, therefore, the operation is convenient and simple. The gate valve of the utility model has the advantages of simple structure, convenient production, capacity for greatly reducing use cost, and easy popularization.
Description
Technical field
The utility model relates to a kind of gate valve, relates in particular to a kind of gate valve of changing parts and having reduced user cost be convenient to.
Background technique
The valve gap of the common gate valve that on market, is circulating at present generally all is to adopt integrated type to be connected with Stuffing box; Be provided with valve rod in valve gap and the Stuffing box; Rotation valve rod drives the flashboard that is suspended on the Stem Mut and rises or descend, with the purpose of the opening and closing that reach valve.Because valve gap and Stuffing box are the structures of integral type, when wherein all can't changing separately after any parts damages, thereby cause whole gate valve to be scrapped, user cost is big.
The model utility content
The utility model purpose is that a kind of gate valve of changing parts and having reduced user cost be convenient to is provided for the deficiency that overcomes existing technology.
For achieving the above object, the technological scheme that the utility model adopts is: a kind of gate valve, comprise valve gap, Stuffing box and valve rod, and said valve rod is installed in valve gap and the Stuffing box, is provided with supporting ring in the said Stuffing box; Said supporting ring is fixedly connected with valve gap.
Preferably, said supporting ring is welded on the valve gap.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The gate valve of the utility model, owing to be provided with supporting ring in the Stuffing box, supporting ring is fixedly connected with valve gap; When valve gap or Stuffing box damage, only need make supporting ring separate with valve gap, just can change parts; More finish changing behind the new parts they have been adorned again getting final product, easy to operate simple.The utility model is simple in structure, is convenient to produce, and greatly reduces user cost, is easy to promote.
Description of drawings
Below in conjunction with accompanying drawing the utility model technological scheme is described further:
Accompanying drawing 1 is the structural representation of the gate valve of the utility model;
Wherein: 1, valve gap; 2, Stuffing box; 3, valve rod; 4, supporting ring.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
The described a kind of gate valve of the utility model shown in accompanying drawing 1 comprises valve gap 1, Stuffing box 2 and valve rod 3, and said valve rod 3 is installed in valve gap 1 and the Stuffing box 2, is provided with supporting ring 4 in the said Stuffing box 2; Said supporting ring 4 is fixedly connected with valve gap 1; Said supporting ring 4 is welded on the valve gap 1.
In long-term use, because the frequent rotation of valve rod 3 can cause valve gap 1 or Stuffing box 2 to damage; When valve gap 1 or Stuffing box 2 damages, the solder joint of supporting ring 4 with valve gap 1 destroyed, can valve gap 1 be separated with Stuffing box 2; After changing new valve gap 1 and Stuffing box 2, supporting ring 4 is installed in the Stuffing box 2, welds supporting ring 4 and valve gap 1 again and promptly accomplished the replacing parts; Simple to operation, greatly reduce user cost, be easy to promote.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, all drop within the utility model rights protection scope.
