Abstract
An oblique angle type stoppage check valve is composed of a valve body, a slotted countersunk head screw, a press ring, a sealing ring, a valve clack, a spring, a valve cover, a valve rod, a sealing pad, fillers, a filler press sleeve, a filler press cover, a hand wheel and the like. The sealing pad is arranged between the valve body and the valve cover, the valve cover is in flange or threaded connection, the valve body is in oblique angle type, and channel cross points in the valve body are in oblique angle transition connection. The filters are arranged between the valve cover and the filler press sleeve, the filler press cover is positioned on the filler press sleeve, one end of the valve rod is connected on the valve clack, the other end of the valve rod is connected on the hand wheel, and the valve rod is in unfixed connection with the valve clack. The spring is positioned between the valve clack and the valve cover, the valve clack is in a T shape, a groove is positioned on a T-shaped head, the sealing ring is embedded in the groove, the sealing ring is in soft or hard sealing, the press ring is positioned outside the sealing ring and fixed by the slotted countersunk head screw, and the slotted counter sunk head screw is in a sunk type structure. The oblique angle type stoppage check valve has the advantages of being energy-saving, good in generality, convenient to overhaul and capable of reducing engineering cost and the number of valves in use.
Description
Technical field:
The utility model relates to a kind of safety check, and particularly a kind of oblique angle type screw down nonreturn valve has by following check function and energy-conservation, characteristics such as versatility good, maintenance is convenient, reduction engineering cost.
Background technique:
That supplies on the market has only the right angle screw down nonreturn valve all the time.And right-angle type screw down nonreturn valve runner is 90 °, and flap is opened great efforts, again because runner is the right angle; Medium is through out-of-date change direction; Lose most of energy, thus when medium through energy loss behind the valve about 1/3 to 2/3, and the right-angle type screw down nonreturn valve is installed between peace big.
The model utility content:
Technical deficiency to existing the said goods; The purpose of the utility model just provides a kind of oblique angle type screw down nonreturn valve, and it is made up of valve body, slotted countersunk flat head screw, trim ring, seal ring, flap, spring, valve gap, valve rod, sealing gasket, filler, filler gland, Gland, handwheel, elastic washer and nut.
The utility model solves the technological scheme that its technical problem adopted: valve body and valve cover chamber are provided with sealing gasket, and described valve gap is the flange connection or is threaded that described valve body is an oblique angle type, and valve body internal channel point of intersection is that the oblique angle transition connects; Filler is located between valve gap and filler gland, and Gland is located on the filler gland; Valve rod one end is connected on the flap, and the other end connects handwheel, and described valve rod and flap be not for being fixedly connected; Be provided with spring between flap and the valve gap, the flap shape is a T shape, and T shape head is provided with groove; Be embedded with seal ring, described seal ring is soft seal or hard sealing, and the seal ring outside is provided with trim ring; And fix with slotted countersunk flat head screw, slotted countersunk flat head screw is the sunk structure.
The utility model beneficial effect: beautiful shape, energy-conservation, versatility good, maintenance is convenient, reduce engineering cost, reduce valve usage quantity characteristics.
Description of drawings:
Accompanying drawing 1 is the utility model overall structure schematic representation
Among the figure, 1 valve body, 2 slotted countersunk flat head screws, 3 trim rings, 4 seal rings, 5 flaps, 6 springs, 7 valve gaps, 8 valve rods, 9 sealing gaskets, 10 fillers, 11 filler glands, 12 Glands, 13 handwheels, 14 elastic washers, 15 nuts
Embodiment:
According to Fig. 1, shown in 2; The utility model provides a kind of oblique angle type screw down nonreturn valve; It is made up of valve body 1, slotted countersunk flat head screw 2, trim ring 3, seal ring 4, flap 5, spring 6, valve gap 7, valve rod 8, sealing gasket 9, filler 10, filler gland 11, Gland 12, handwheel 13, elastic washer 14, nut 15; Oblique angle type cut-off non-return valve arrangement compresses sealing gasket 9 by valve body 1 through the valve gap 7 of screwing and realizes the valve outside seal; The valve rod 8 places sealing of valve is that Gland 12 compresses filler gland 11 and filler 10 is realized sealing through rotating.
This valve adopts 45 ° angle, and all angles of body cavity adopt the transition runner, and cavity does not have the dead angle, effectively reduces flow loss.Valve rod 8 and flap 5 be not for being fixedly connected; Be provided with spring 6 between flap 5 and the valve gap 7, flap 5 shapes are T shapes, and T shape head is provided with groove; Be embedded with seal ring 4, seal ring 4 can be soft seal or hard sealing, and seal ring 4 outsides are provided with trim ring 3; And fixing with slotted countersunk flat head screw 2, slotted countersunk flat head screw 2 is sunk structures.Flap 5 is done the running of piston gap with valve gap 7; Between flap 5 and the valve gap 7 and be provided with spring 6 auto-reset functions; When valve rod 8 rises, go up valve and be equivalent to safety check, the keying campaign of flap 5 is decided with the flow direction of working medium, and medium promotes flap 5 during the medium following current; Valve is opened through handwheel 13, and handwheel 13 is fixed on the valve rod 8 through elastic washer 14, nut 15; Flap 5 falls after rise downwards under medium and spring 6 effects during medium counter flow, makes valve closing.When actuator is pressed on 5 last times of flap with valve rod 8, this valve is equivalent to stop valve, stops the inflow of medium.Rationally dexterously two kinds of valves are united two into one, this oblique angle type screw down nonreturn valve has compact structure, open flexibly, and reliable performance, characteristics such as easy to operate can be widely used in the devices such as medicine, food, petrochemical industry and chemical industry chemical fertilizer, metallurgy, electric power.
