Abstract
The utility model relates to a fast switching stop valve, which comprises a valve body, a handle, a gland, a sealing ring and a valve rod. The utility model is characterized in that an eccentric shaft connected with the valve rod is arranged on a cam wheel structure on one end of the handle. The other end of the valve rod is connected with a sealing valve flap. The contact face between a sealing valve flap and the valve body adopts the circle art sealing structure. A sealing spring is arranged between the valve flap in the valve body and the gland. Because the rotation of the handle eccentric cam can be used for controlling the switching of the valve, the utility model has the advantages of short time, rapid and flexible switching, low manipulation labor strength, simple structure, easy production, low cost, long service life, etc.
Description
The utility model belongs to valve class technical field, specifically a kind of improvement to industrial or civil stop valve.
Be installed in all gases at present.Liquid storage narrow-necked earthen jar.Groove narrow-necked earthen jar and various chemical industry equipment device and various civilian on.Stop valve on the drainage pipeline adopts handwheel to drive the screw thread valve rod usually and controls its switch, and shortcoming is that manipulation labor intensity is big, and switching time is long.Complex structure.The manufacture cost height.The easy-to-rust malfunctioning switch, working life is short etc.
The purpose of this utility model provides a kind of handle that utilizes and starts the stop valve that is used for controlling its snap switch that eccentric cam is controlled its stroke and self-closing spring.
The purpose of this utility model is achieved in that it includes valve body, handle, gland, seal ring.Valve rod, the circular cam structure that it is characterized in that handle one end is provided with the eccentric shaft that is connected with valve rod, the other end at valve rod is connected with a sealing flap, and sealing flap and valve body surface of contact adopt the circular arc line sealing configuration, are provided with Packing spring between flap in valve body and the gland.During operation, handle and on eccentric cam rotate 180 degree, actuate valve stem drives flap and upwards slides, valve wide open opens, medium enters valve cavity by import, is discharged by outlet; Handle is backward rotation 180 degree again, and valve rod drives the effect that flap leans on self-closing Packing spring simultaneously, automatic-closing valve.
The utility model comes the switch of control valve owing to utilize the rotation of handle eccentric cam, therefore has the time weak point.Switch is quick.Flexibly.Manipulation labor intensity is low.And it is simple in structure.Be easy to make.Cost is low.Long service life.Advantages such as applied range.
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
Fig. 1 is a sectional structure schematic representation of the present utility model
By shown in Figure 1,1 is valve body. and 4 are valve rod. and 6 are gland. and 8 are handle, and the circular cam structure of handle 8 one ends is provided with the eccentric shaft 7 that is connected with valve rod 4, rotate the opening travel that 180 degree come control valve by its handle, realize the effect of snap switch.The other end at valve rod is connected with a sealing flap 2, and this flap adopts the iron chains dress not to be subjected to the teflon of any dielectric corrosion, and sealing flap 2 adopts the circular arc line sealing configuration with valve body 1 surface of contact, is provided with Packing spring 3 between flap in valve body and the gland 6.Inboard iron chains at gland 6 are equipped with the sealing rubber ring 5 that seals with valve rod 4 sliding contacts in addition.During operation, handle with sleeve makes the eccentric cam of one end rotate 180 degree, and actuate valve stem 4 drives flap 3 and upwards slides, and valve wide open opens, and medium enters valve cavity by import, and is discharged by outlet; Handle is backward rotation 180 degree again, and valve rod drives the effect that flap is got back to original position and leaned on self-closing Packing spring simultaneously, automatic-closing valve.The valve body structure of above-mentioned Fig. 1 can be selected for use according to different devices: straight-through type, Three way type, angie type; Optional usage connects, and internal and external screw thread connects.Patterns such as fast-assembling connection, welding.
