Abstract

The utility model discloses a novel cut-off valve. The novel cut-off valve comprises a valve body, a valve rod, a gate plate and a gate plate sealing clamp groove, wherein the gate plate is clamped with the valve rod; the top of the upper end of the valve rod is welded with a wrench; the gate plate is circular; the valve rod is in threaded connection with the valve body; the clamping groove and the gate plate are on a straight line; the width of the clamping groove is slightly greater than the thickness of the gate plate; sealing gaskets are arranged on both sides of the clamping groove; a sealing gasket is arranged at on the sealing part between the gate plate and the valve body. Preferably, the lower end of the threaded connection part between the valve rod and the valve body is provided with an O-shaped seal ring around the valve rod. Preferably, the valve body is of a cast iron one-time molded structure. The novel cut-off valve has the beneficial effects that the structure is simple, and the high pressure resistance is strong, the sealing property is good and the service life is greatly prolonged since the clamping groove is arranged below the gate plate.

Description

A kind of novel block valve
Technical field
The utility model belongs to valve field, particularly a kind of novel block valve.
Background technique
Tradition block valve or flashboard is thick, or complex structure, cost of production is high, and resistance to pressure is low, and high-pressure situations flashboard will move, and causes sealing poor.
Model utility content
For the deficiencies in the prior art, the utility model provides a kind of novel block valve of good airproof performance.
To achieve these goals, technical solution adopted in the utility model is:
A kind of novel block valve, comprise valve body, valve rod and flashboard, flashboard and valve rod clamping, valve rod upper end welded top has spanner, and described flashboard is circular, valve rod and valve body are threaded connection, also comprise flashboard sealing draw-in groove, draw-in groove and flashboard are straight line, and draw-in groove width is a bit larger tham flashboard thickness, draw-in groove both sides are equipped with sealing gasket, and flashboard and valve seal place are provided with sealing gasket.
As preferably, valve rod and lower end, valve body screw thread joint are positioned at valve rod and are provided with O RunddichtringO around.
As preferably, described valve body adopts cast iron once-through structure.
The beneficial effects of the utility model: the utility model is simple in structure, owing to having draw-in groove at flashboard, barotolerance is strong, good seal performance, greatly increase working life.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
A kind of novel block valve as shown in Figure 1, comprise valve body 1, valve rod 3 and flashboard 2, flashboard 2 and valve rod 3 clampings, valve rod 3 upper end welded top have spanner 4, and described flashboard 2 is circular, valve rod 3 is threaded connection with valve body 1, also comprise flashboard 2 sealing draw-in grooves 7, draw-in groove 7 is straight line with flashboard 2, and draw-in groove 7 width are a bit larger tham flashboard 2 thickness, draw-in groove 7 both sides are equipped with sealing gasket 5, and flashboard 2 is provided with sealing gasket 5 with valve body 1 sealing place.Valve rod 3 is positioned at valve rod 3 with valve body 1 lower end, threaded connection place and is provided with O RunddichtringO 6 around.Described valve body 1 adopts cast iron once-through structure.
The utility model is simple in structure, and owing to having draw-in groove 7 at flashboard 2, barotolerance is strong, good seal performance, and greatly increase working life.
Be more than the utility model preferred forms, those ordinary skill in the art's simple change and replacement are all within protection domain of the present utility model.
