Description

A kind of jacket heat-preservation Oblique Stop Valves

Technical field

The utility model belongs to shut-off valve technical field, and in particular to a kind of jacket heat-preservation Oblique Stop Valves.

Background technique

Shut-off valve is also known as pipe valve valve, belongs to forced seal formula valve, so when valve is closed, it is necessary to apply to flap and press Power is not leaked with forced seal face.The opening and closing element of shut-off valve is the flap of stopper, and sealing is above in plane or the extra large conical surface, flap Center line along valve seat is for linear motion.The forms of motion of valve rod also has lifting rotation rod-type to can be used for controlling empty gas and water, steaming The flowing of the various types fluids such as vapour, various corrosive medias, mud, oil product, liquid metal and radiating medium.Therefore, this The shut-off valve valve that shuts off of seed type is highly suitable as cutting off or adjusting and throttling is used.Since the valve rod of such valve is opened Or shutoff stroke is relatively short, and has very reliable cutting function, and due to the row of the variation of valve seat port and flap Journey direct proportionality is very suitable for the adjusting to flow.

Easily cause erosion and scratch between current cut-off valve sealing surface, in long-time uses axial load it is excessive so that Bearing is easy to damage, is easily shut off when flow is larger, is easy to produce blocking by the big fluid containing solid particle or viscosity.

Utility model content

The purpose of this utility model is to provide a kind of jacket heat-preservation Oblique Stop Valves, to solve in above-mentioned background technique The problem of proposition.

To achieve the above object, the utility model provides the following technical solutions: a kind of jacket heat-preservation Oblique Stop Valves, until It less include valve body, movable handwheel, thrust bearing, valve rod, valve shaft, valve block, pre- valve closing block, valve-rod cavity, feed inlet, discharge port, folder Set, body base, screw thread and fixed frame, the valve body material are monel metal, and the valve body surfaces externally and internally is coated with nothing Toxicity powder epoxy resin, the body base are provided with collet, and the folder is set on body base, is inside the collet Feed inlet is arranged in circular vacuum cavity, the body base left end, and discharge port is arranged in right end.

Preferably, the top of the valve body is equipped with movable handwheel, and the activity handwheel is cirque structure, the movable hand Wheel surface is enclosed with insulating rubber, is connected with valve rod below the activity handwheel, the valve stem top is equipped with thrust bearing.

Preferably, described to be set in movable handwheel and valve rod junction with thrust bearing, the thrust bearing is stopped by two Pushing pad piece and several rolling steel balls composition.

Preferably, there is valve block in the bottom of the valve rod by mechanical connection by mechanical connection valve shaft, the valve shaft bottom, The valve block bottom is equipped with pre- valve closing block, and face pressure is equipped with rubber membrane inside and outside the valve block.

Preferably, the valve shaft, valve block and pre- valve closing block are both placed in valve-rod cavity.

Preferably, there is screw thread on the valve rod, fixed frame is installed on the valve rod.

The technical effect and advantage of the utility model: the jacket heat-preservation Oblique Stop Valves is smeared in valve block surfaces externally and internally There is epoxy resin to enhance corrosion resistance to improve water quality, and technology is obtained using membrane pressure inside and outside valve block and suppresses one layer of rubber Film, so that the pre- valve closing block being arranged when closing is required blocks half first in the even closer of valve closing, just for valve block True close reduces resistance, can effectively bear axial load by setting thrust bearing bearing life is extended, designs Y shape shut-off valve, the runner and sprue of valve body are at an oblique line, and the extent of the destruction of such flow regime is than conventional shut-off valve It is small, it is also corresponding small by the pressure loss of valve, so that it is not likely to produce blocking, and the jacket heat-preservation Oblique Stop Valves, tool Have the advantages that safely and effectively, it is environmentally-friendly sanitary, practical reliable, can be used with popularity.
