Abstract
This utility model relates to a kind of repid cut-off valve, including actuator, the outfan of actuator is connected with one end of mandrel by pipeline leakage plugging device, the other end of mandrel is connected with the top of spool, spool is coated with by the pedestal of a pair valve seat composition, and pedestal is positioned at valve body, and the spool mounting groove groove face that the periphery of spool and each valve seat are offered abuts against, also setting up guide pin bushing in described pedestal, guide pin bushing is connected with the bottom of spool；The first half peripherally disposed formation spherical portion of described spool, the peripherally disposed formation in the lower half conus portion of spool.This utility model simple in construction, easy to use, it is effectively increased the service life of valve body by being arranged to conus portion in the bottom of spool, spool and valve seat, guide pin bushing coordinate the fluency that ensure that Spool rotating, spool is good from close energy-absorbing, more stable relative to roof-mounted eccentric ball valve the latter half, it is used in the feed system being more switched fast.
Description
Technical field
This utility model relates to valve body field, particularly relates to a kind of repid cut-off valve.
Background technology
At present, existing stop valve structure is mainly general ball valve and roof-mounted eccentric ball valve, the most roof-mounted eccentric sphere
Valve is applicable to High Pressure Difference, needs the occasion of frequent switching action, and the valve body life-span is substantially reduced after a long time use, it is impossible to more accelerate
The switching of speed, greatly reduces service efficiency.
Utility model content
The applicant, for above-mentioned existing issue, has carried out Improvement, it is provided that a kind of repid cut-off valve, it is applicable to more
Add the feed system being switched fast, applied widely, substantially increase the service life of valve body.
The technical scheme that this utility model is used is as follows:
A kind of repid cut-off valve, including actuator, the outfan of described actuator is by pipeline leakage plugging device and the one of mandrel
End connects, and the other end of described mandrel is connected with the top of spool, and spool is coated with by the pedestal of a pair valve seat composition, described pedestal
Being positioned at valve body, the spool mounting groove groove face that the periphery of described spool and each valve seat are offered abuts against, and also sets in described pedestal
Putting guide pin bushing, described guide pin bushing is connected with the bottom of spool；The first half peripherally disposed formation spherical portion of described spool, described
The peripherally disposed formation in the lower half conus portion of spool.
Its further technical scheme is:
Described pipeline leakage plugging device runs through and is installed in connection support, and described mandrel runs through and is installed in upper cover, described connection support
It is connected by trip bolt with upper cover；
Described upper cover is connected with pedestal.
The beneficial effects of the utility model are as follows:
This utility model simple in construction, easy to use, it is effectively increased valve by being arranged to conus portion in the bottom of spool
The service life of body, spool and valve seat, guide pin bushing coordinate the fluency that ensure that Spool rotating, spool is good from close energy-absorbing, spool
Being produced additional buoyancy by medium effect in rotary course, reduce driving force, therefore it is applicable to less actuator, its
More stable relative to roof-mounted eccentric ball valve the latter half, it is used in the feed system being more switched fast.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, actuator；2, support is connected；3, pipeline leakage plugging device；4, mandrel；5, spool；501, spherical portion；502, circular cone
Portion；6, valve seat；7, guide pin bushing；8, valve body；9, upper cover；10, trip bolt.
Detailed description of the invention
Below in conjunction with the accompanying drawings, detailed description of the invention of the present utility model is described.
As it is shown in figure 1, a kind of repid cut-off valve includes actuator 1, the outfan of actuator 1 by pipeline leakage plugging device 3 with
One end of mandrel 4 connects, and the other end of mandrel 4 is connected with the top of spool 5, and spool 5 is wrapped by the pedestal of a pair valve seat 6 composition
Covering, pedestal is positioned at valve body 8, and the spool mounting groove groove face that the periphery of spool 5 and each valve seat 6 are offered abuts against, in pedestal also
Arranging guide pin bushing 7, guide pin bushing 7 is connected with the bottom of spool 5；The first half peripherally disposed formation spherical portion 501 of spool 5, valve
The peripherally disposed formation in the lower half conus portion 502 of core 5, the layout of conus portion 502 is effectively increased the life-span of spool, keeps away
Exempt from the flimsy problem in original ball valve bottom, the internal wedge structure being provided for coordinating conus portion 502 of each valve seat 6, its tool
There is automatic compensation gap function, high from close performance, more stable relative to the latter half of roof-mounted eccentric ball valve, as it is shown in figure 1,
Above-mentioned pipeline leakage plugging device 3 runs through and is installed in connection support 2, and mandrel 4 runs through and is installed in upper cover 9, connects support 2 and passes through with upper cover 9
Trip bolt 10 connects, and above-mentioned upper cover 9 is connected with pedestal, and above-mentioned actuator 1 can be electric operator or pneumatic execution
Any one of mechanism.
Specific works process of the present utility model is as follows:
As it is shown in figure 1, rotated by actuator 1 (pneumatic), the outfan of actuator 1 is rotated and is carried by pipeline leakage plugging device Ei
Moving mandrel 4, owing to one end of mandrel 4 is connected with the top of spool 5, is therefore driven spool 5 to make 90 ° of rotations, guide pin bushing 7 by mandrel 4
Layout ensure that the rotary motion of spool 5, thus achieve the opening and closing of valve body, spool 5 in rotary course by medium effect
Produce additional buoyancy, reduce driving force, therefore can use less actuator, reduce entreprise cost.
Above description is to explanation of the present utility model, is not the restriction to utility model, and this utility model is limited
Scope sees claim, and in the case of basic structure of the present utility model, this utility model can make any shape
The amendment of formula.
