Abstract
Disclosed is an axial sealing device. The axial sealing device is composed of a valve body, a valve rod, a valve clack, a special-shaped sealing ring and a sealing gland. The valve rod is arranged inside the valve body. The special-shaped sealing ring is arranged between the valve body and the valve rod. The sealing gland is arranged outside the valve body. The sealing gland is connected with the valve body through a compression screw. The sealing gland makes contact with the special-shaped sealing ring. The special-shaped sealing ring is composed of three annular sealing ring bodies. When the valve is opened or closed, a medium enables the valve rod to be inclined, the special-shaped sealing ring deforms due to the extrusion, an inner lip and an outer lip of the special-shaped sealing ring can be tightly attached to the valve rod and the valve body, and therefore the sealing and anti-leakage effects are achieved. The axial sealing device has the advantages of being simple in structure, reliable in sealing performance, and not prone to leakage.
Description
Technical field
The utility model relates to a kind of seal arrangement, particularly axial sealer.
Background technique
Valve is in fluid system, is used for controlling direction, the pressure of fluid, the device of flow.Valve is the device that pipe arrangement and the interior medium (liquid, gas, powder) of equipment is flowed or stop and controlling its flow, it is controlling component in the pipeline fluid transporting system, it is for changing path section and media flow direction, has the functions such as water conservancy diversion, cut-off, throttling, non-return, shunting or overflow release.The valve rod sealing device of general valve, comprise valve body, valve rod, O RunddichtringO and sealing gland, in described valve body, be provided with valve rod, be provided with the O RunddichtringO between described valve body and valve rod, described valve body is provided with sealing gland outward, and described sealing gland contacts with the O RunddichtringO.Such valve rod sealing device when mounted, at first is inserted in the O RunddichtringO, then sealing gland is being installed, for compressing the O RunddichtringO, because the amount of deformation of O RunddichtringO is less, when the assembling magnitude of interference of sealing gland is large, easily damage the O RunddichtringO by pressure, make sealability lose efficacy; And certain interval is arranged between valve rod and valve body, and during valve switch, medium can make valve rod tilt, and now the sealability of O RunddichtringO can not be guaranteed, and causes leaking.
The model utility content
The utility model, for addressing the above problem, provides a kind of sealability the reliable and difficult valve rod sealing device lost efficacy.
The utility model adopts following technological scheme:
Axial sealer, be comprised of valve body, valve rod, flap, special-shaped seal ring and sealing gland.
Be provided with valve rod in described valve body, between described valve body and valve rod, be provided with special-shaped seal ring, described valve body is provided with sealing gland outward, and described sealing gland is connected with valve body by housing screw; Described sealing gland contacts with special-shaped seal ring.Described special-shaped seal ring is comprised of three O-ring seals.
When valve opening is closed, medium makes valve rod tilt, special-shaped seal ring be squeezed occur deformation make special-shaped seal ring in lip, outer lip still can be close to valve rod and valve body, thereby reach the effect of sealing anti-leak.
The utility model has the advantage of: simple in structure, sealability is reliable, is difficult for causing leakage.
The accompanying drawing explanation
Fig. 1 is the utility model complete section structural representation.
Wherein: 1. valve body, 2. valve rod, 3. flap, 4. sealing gland, 5. housing screw, 6. special-shaped seal ring.
Embodiment
Below in conjunction with Fig. 1 and embodiment, the utility model is further explained to explanation.
Shown in Fig. 1, axial sealer, be comprised of valve body 1, valve rod 2, flap 3, special-shaped seal ring 6 and sealing gland 4.
Be provided with valve rod 2 in described valve body 1,2 of described valve body 1 and valve rods are provided with special-shaped seal ring 6, the outer sealing gland 4 that is provided with of described valve body 1, and described sealing gland 4 is connected with valve body 1 by housing screw 5; Described sealing gland 4 contacts with special-shaped seal ring 6.Described special-shaped seal ring 6 is comprised of three O-ring seals.
During installation, at first be inserted in special-shaped seal ring 6, then by housing screw 5, sealing gland 4 is connected with valve body 1, for compressing special-shaped seal ring 6, because the amount of deformation of special-shaped seal ring 6 is large, when even the assembling magnitude of interference of sealing gland 4 is large, also not fragile special-shaped seal ring 6, sealability is difficult for losing efficacy; When valve opening is closed, medium makes valve rod 2 tilt, special-shaped seal ring 6 be squeezed occur deformation make special-shaped seal ring 6 in lip, outer lip still can be close to valve rod 2 and valve body 1, thereby reach the effect of sealing anti-leak.
