Abstract
The utility model discloses a valve body of cast steel gate valve, including valve body, flange, sealed face, bellmouth and screw hole, the end erection joint is imported and exported to the valve body has the flange, be equipped with the screw hole along the circumferencial direction on the flange, be equipped with the bellmouth on the flange of valve body exit one end, be equipped with sealed face in the exit of valve body on the terminal surface, the utility model discloses an adopt soft sealing connection with valve body and pipeline, the installation is difficult to misplace, and the processing volume is few, and the terminal surface design was difficult for leaking for the wedge in the valve body was imported and exported, difficult collection sediment, and interchangeability is good, and it is convenient to dismantle, to keep in repair, to change, long service life.
Description
[technical field]
This utility model relates to the technical field of gate valve, particularly the technical field of the valve body of a kind of cast steel gate valve。
[background technology]
Valve body is a main parts size in valve, different mechanical manufacturing method is had according to pressure rating, such as: casting, forging etc., the valve body of mesolow specification generally adopts casting technique to produce valve body, the valve body of mesohigh specification adopts Forging Technology to produce, pressure medium can be effectively born after collectively forming sealing with spool and valve seat insert, the material of valve body is according to different processing mediums, select different metal materials, conventional material has: cast iron, cast steel, rustless steel, carbon steel etc., at present in water conservancy, fire-fighting, oil, the pipeline fluid control field of the industries such as chemical industry, the gate valve commonly used and the connection of plumbing installation are by welding or Flange joint realizes, and adopt these connected mode processing capacities big, sealing property is poor。
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, the valve body of a kind of cast steel gate valve is proposed, can make gate valve and plumbing installation is by welding realization, but when welding junction has leak source cannot to operate by band water when needing to rush to repair, and be not easy to dismounting, maintenance after life-time service and change。
For achieving the above object, the utility model proposes the valve body of a kind of cast steel gate valve, including valve body, flange, sealing surface, bellmouth and screwed hole, described valve body entrance end is installed and is connected to flange, described flange is along the circumferential direction provided with screwed hole, described valve body is imported and exported the flange of one end and is provided with bellmouth, and the import and export inner face of described valve body is provided with sealing surface。
As preferably, adopting soft seal connected mode between import and export and the pipeline of described valve body。
As preferably, described valve body adopts casting one-shot forming。
As preferably, described sealing surface is wedge shape end face, described wedge shape end face realizes by inlaying rubber the sealing of valve body and pipeline, compression is connected cooperation。
The beneficial effects of the utility model: this utility model, by adopting soft seal to be connected with pipeline valve body, is installed and not easily misplaced, and processing capacity is few, valve body is imported and exported inner face and is designed as wedge shape, not easily leaks, not easily collects slag, interchangeability is good, and demolition, repair, replacement are convenient, long service life。
Feature of the present utility model and advantage will be described in detail in conjunction with accompanying drawing by embodiment。
[accompanying drawing explanation]
Fig. 1 is the structural representation of the valve body of a kind of cast steel gate valve of this utility model,
Fig. 2 is the side cutaway view of the valve body of a kind of cast steel gate valve of this utility model。
In figure: 1-valve body, 2-flange, 3-sealing surface, 4-bellmouth, 5-screwed hole。
[detailed description of the invention]
Consult Fig. 1 and Fig. 2, the valve body of a kind of cast steel gate valve of this utility model, including valve body 1, flange 2, sealing surface 3, bellmouth 4 and screwed hole 5, described valve body 1 entrance end is installed and is connected to flange 2, described flange 2 is along the circumferential direction provided with screwed hole 5, described valve body 1 is imported and exported the flange 2 of one end and is provided with bellmouth 4, the import and export inner face of described valve body 1 is provided with sealing surface 3, soft seal connected mode is adopted between import and export and the pipeline of described valve body 1, described valve body 1 adopts casting one-shot forming, described sealing surface 3 is wedge shape end face, described wedge shape end face realizes the sealing of valve body 1 and pipeline by inlaying rubber, compress to connect and coordinate。
Utility model works process:
The valve body of a kind of cast steel gate valve of this utility model is in the course of the work, by adopting soft seal to be connected with pipeline valve body 1, install and not easily misplace, processing capacity is few, and valve body 1 is imported and exported inner face and is designed as wedge shape, not easily leaks, not easily collect slag, interchangeability is good, and demolition, repair, replacement are convenient, long service life。
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, any scheme after this utility model simple transformation is belonged to protection domain of the present utility model。
