Abstract

The invention relates to a valve, in particular to a soft seal abrasion resisting slag discharging valve. The soft seal abrasion resisting slag discharging valve comprises a valve body, a valve cover,a valve plate and a lead screw. The upper end of the valve cover is connected with a support, the valve plate is arranged in the valve body, the inner end of the lead screw penetrates the valve coverand is fixedly connected with the upper end of the valve plate, and the outer end of the lead screw is supported on the support. The inlet end of the valve body is connected with an inlet outer sleeve and an inlet inner sleeve, the outlet end of the valve body is connected with an outlet outer sleeve and an outlet inner sleeve, and the outlet end of the inlet outer sleeve stretches into the valvebody and is sealed and fixed to the inlet part of the valve body. Seal filling is arranged between the inlet outer sleeve and the inlet inner sleeve, the inlet end of the outlet inner sleeve and theinlet end of the outlet outer sleeve are closely attached to the outlet end face of the valve body, and the outlet outer sleeve and the end face of the valve body are fixedly connected through a flange and a bolt. Seal filling is arranged between the outlet inner sleeve and the outlet outer sleeve, and the inlet inner sleeve and the outlet inner sleeve are made of abrasion resisting alloys. By means of the above arrangement, the abrasion resisting degree of an inlet and an outlet of a gate valve can be greatly improved, and the service life of the gate valve is greatly prolonged; the inlet inner sleeve, the inlet outer sleeve, the outlet inner sleeve and the outlet outer sleeve can be replaced, and the equipment repairing cost is reduced.

Description

technical field [0001] The invention relates to a valve, in particular to the technical field of manufacturing a manual slag discharge valve. Background technique [0002] The slag discharge gate valve is suitable for the hydraulic system of the thermal power station and the mortar discharge system pipeline of the hydraulic project with a nominal pressure PN1.6 ~ 6.4MPa and an operating temperature of 0 ~ 100 ° C. It cuts off or connects the gray water mixture and the slag water mixture in the pipeline. It is mainly used in the water ash removal system of thermal power plants, mine tailings transportation, sewage discharge and oil transportation and other pipelines. At present, there are some problems in the use of gate valves. For example, slag is easy to accumulate at the bottom of the valve body, which makes the valve plate not close properly. scrapped. Contents of the invention [0003] In order to overcome the defects of the existing slag discharge gate valve, the i...
