Abstract
The utility model belongs to a mechanical product, which is suitable for using in petroleum and chemical fields; the device is an improvement of a high-pressure valve, which mainly comprises a valve body, a bushing and a valve core and a press cover, a seal ring. The gate of the valve is made into a cone shape made; the connection of two ends of the gate is a hoop connection; the gate is integrated with a screw as a whole body. The device has advantages of less seal surface and lubricating point, good seal performance, not easy leakage. The valve can also play a role of flow regulation with longer working life, convenient installation and operation, reliable and lessen labor intensity.
Description
One, technical field:
The utility model belongs to engineering goods, is applicable to fields such as oil, chemical industry, is kind of a high pressure valve.
Two, technical background:
Original some high pressure valves that use in fields such as oil, chemical industry, its shortcoming was: seal point is many, easy to leak, flashboard easily come off, valve closing is not tight, and knife switch is heavy, lack working life, increased maintenance cost and working strength of workers.
Three, summary of the invention:
The utility model makes a kind of rotary valve in order to overcome the defective of above-mentioned high pressure valve through improving.It mainly is made of valve body, lining and spool and gland, seal ring, and the flashboard that its maximum feature is this valve is a cone shape, and the gate two ends are connected to clip connected; Because flashboard is cone shape, make the surface of contact between flashboard and the valve body can be tighter, the water phenomenon appearred when avoiding flashboard to close.Flashboard and leading screw are made as one, can prevent that flashboard from coming off, and this flashboard was both rotatable, again can on carry knife switch since also can switch freely, needn't be by other instrument, safety, use, change all convenient.
The main beneficial effect of the utility model is that sealing surface and lubricating point are few, good seal performance, easy to leak not like this, this valve also has the function of regulating flow, the size of taper flashboard perforate just correspondingly influences the flow size, but regulated at will, can also improve working life, easy to use, reliable, reduce labor intensity.
Four, description of drawings:
As figure is a kind of structural representation of rotary valve.
Explain: 1, valve body, 2, lining, 3, the O RunddichtringO, 4, the O RunddichtringO, 5, loam cake, 6, gland, 7, nut, 8, swivel nut, 9, handle, 10, spool,
Five, embodiment:
As shown in the figure, cartridge spool 10 in the valve body 1 is equipped with lining 2 and O RunddichtringO 3,4 between valve body 1 and spool 10, loam cake 5 is fixed by bolt 7 with gland 6, swivel nut 8 is contained in the gland 6, other has fixedly swivel nut 8 of handle 9, and swivel nut 8 is rotatable, and being made by spool 10 lower end flashboards is cone shape, both rotatable, also can realize rotating up and down by swivel nut 8, spool 10 lower ends be installed in valve body central lower position, so that play the rotation positioning effect.
If carry flashboard on can be earlier when using, by valve body swivel nut 8, just can drive leading screw and flashboard moves up and down, the disengaging valve body sealing surface, switch gate correct position falls flashboard more then.Thereby solved the contradiction of the direct rotary switch difficulty of stopcock under the high pressure.And the working life of improving this valve greatly.
