Problems solved by technology

However, the valve seat 07 of this angle-shaped regulating valve is installed in the outlet 083 of the valve body 08 through threads with a special tool, which causes extremely inconvenient product assembly and disassembly, on-site maintenance, etc., and the medium is easy to pass through the valve when the valve is closed. Seat thread leakage, resulting in valve leakage will continue to increase
In addition, due to the harsh working conditions of the angle regulating valve, t

Embodiment Construction

[0020] As shown in Figure 2, the angle regulating valve of the present invention comprises parts such as valve body 08, valve seat 07, valve core 09, valve stem 23, valve cover 13, packing 18, packing gland 19, guide sleeve 10.

[0021] Wherein, the inside of the valve body 08 is a valve cavity 081, which adopts a standard streamlined design structure, which can avoid the impact of the granular medium on the inner wall of the valve. On the side, bottom and top of the valve body 08 are respectively an inlet 082, an outlet 083 and a guide sleeve 084 communicating with the valve chamber 081. The upper part of the valve body 08 is connected to the valve cover 13 through bolts 15 and nuts 14 . There is a stuffing box 131 on the valve cover 13 . The stuffing box 131, the guide sleeve 084, and the outlet 083 are located on the same vertical line. The guide sleeve 10 is installed in the guide sleeve port 084, and the upper part of the guide sleeve 10 has an annular flange on the cir...

Abstract

The invention discloses an angular adjusting valve, comprising a valve body, a valve seat, a valve core, a valve rod, and a valve cover. The valve body is internally provided with a valve chamber; the side part, the lower part and the upper part are respectively provided with an inlet, an outlet and a guide sleeve mouth; the valve rod is arranged on the upper part of the valve body; a guide sleeve is fixed inside the guide sleeve mouth; the lower end of the valve rod is connected with the valve core which motions in the guide sleeve; the upper end of the valve rod passes through out of a stuffing box on the valve cover; the lower end of the valve rod is a connecting head; the valve core is fixed on the connecting head; the surface of the connecting head is provided with a plurality of garbage troughs intermittently. By adopting the technical proposal, the angular adjusting valve of the invention has a self-cleaning function and can avoid that the garbage grains are blocked and abraded in the guide sleeve.

Description

technical field [0001] The invention relates to a regulating valve, in particular to an angle regulating valve used for the control and regulation of black water and slag water in a coal chemical system. Background technique [0002] Angle regulating valve has a simple flow path and self-cleaning performance. It is suitable for unclean media, such as the control and regulation of black water and slag water in coal chemical industry systems. Therefore, angle regulating valve is also commonly known as black water regulating valve. [0003] At present, the widely used angle regulating valve is composed of a valve body, a valve seat, a valve core, a valve stem, a valve cover, a packing and a packing pressure plate and an actuator. The side, bottom and top of the valve body 08 are the inlet 082, the outlet 083, and the guide bushing 084 which communicate with the valve cavity 081 respectively. The outlet 083, the guide hole 084, and the stuffing box 131 are on a vertical line, t...
