Description
Technical field
The utility model belongs to technical field of petroleum extraction, more particularly to a kind of cover-plate type soft seal single current angle valve.
Background technology
Existing ball-and-seat is generally the valve body of flat flow, and its internal flow entrance is this with exporting at grade
Valve body has certain limitation in actual applications, it is impossible to meets actual production needs；And existing valve inner sealing
Face sealing or linear sealing between metal and metal, its sealing effectiveness is poor, and metal easily corrodes.Therefore, it is necessary to existing skill
Art is improved.
The content of the invention
The utility model provides a kind of simple in construction, good sealing effect to solve technical problem present in known technology
Cover-plate type soft seal single current angle valve.
The utility model is adopted the technical scheme that to solve technical problem present in known technology.A kind of cover-plate type
Soft seal single current angle valve, including valve body, the valve body one side and bottom are equipped with clip, and the valve inner is provided with valve seat,
The valve seat bottom is provided with valve element, and the valve core upper sleeve has stage clip, and sealing ring, the valve element and sealing is arranged below in the valve element
Ring is rabbeted, and the junction of the valve element and sealing ring is provided with cushion rubber.
Further, the cushion rubber is arranged to one.
Further, it is provided with the plug with sealing ring above the valve body.
Further, the plug is connected through a screw thread with valve body.
Further, valve body and the clip interlocking.
The utility model has the advantages and positive effects of：The cover-plate type soft seal single current angle valve, it is simple in construction, make
It is convenient, low manufacture cost；Using cushion rubber soft seal, good sealing effect, service life length；Valve body is in 90 degree, thus it is possible to vary fluid
Flow direction, and can effectively prevent reverse flow of fluids, use is wide.
Brief description of the drawings
Fig. 1 is the structural representation for the cover-plate type soft seal single current angle valve that the utility model embodiment provides.
In figure：1st, valve body；2nd, valve seat；3rd, stage clip；4th, valve element；5th, cushion rubber；6th, sealing ring；7th, clip；8th, plug.
Embodiment
For invention, features and effects of the present utility model can be further appreciated that, following examples are hereby enumerated, and coordinate
Accompanying drawing describes in detail as follows.
The structure of cover-plate type soft seal single current angle valve of the present utility model is explained in detail with reference to Fig. 1.It is a kind of
Cover-plate type soft seal single current angle valve, including valve body 1, the top of valve body 1 are provided with the plug 8 with sealing ring, the plug 8 and valve
Body 1 is connected through a screw thread, and the one side of valve body 1 and bottom are equipped with clip 7, and spiral shell is rabbeted or passed through to the valve body 1 and clip 7
Line connects, and the inside of valve body 1 is provided with valve seat 2, and the bottom of valve seat 2 is provided with valve element 4, stage clip 3, institute are cased with the valve element 4
State valve element 4 and sealing ring 6 is arranged below, the valve element 4 is rabbeted with sealing ring 6, and the junction of the valve element 4 and sealing ring 6 is provided with
Cushion rubber 5, the cushion rubber 5 are arranged to one.
Operation principle：During work, fluid circuit is imported and exported loaded on valve body 1 on the clip 7 at both ends, and the band of the top of valve body 1 is close
The plug 8 of seal is screwed into inside valve body 1, and stage clip 3 is fastened, so as to further compress valve element 4.Stage clip 3 exists
Pressure transmission is made the cushion rubber 5 on valve element 4 closely rabbet with sealing ring 6 and reach sealing effectiveness to valve element 4 during compression.
When the pressure in the direction of entrance valve element 4 is more than outlet pressure, fluid compression stage clip 3, cause valve element 4 under pressure to stage clip
3 directions are moved, and open valve immediately, fluid can pass through.And the cushion rubber 5 between valve element 4 and sealing ring 6 makes to realize therebetween
Soft seal, not only good seal, low manufacture cost, and service life are grown.The cover-plate type single current angle valve is also known as check-valves, suitable for each
Kind of fluid circuit uses, this check-valves can only the flow direction of low in and high out installed, when bottom inlet pressure is less than eminence
During outlet pressure, then whole valve positive closing in the presence of stage clip 3, so as to prevent reverse flow of fluids.The cover-plate type is soft close
Seal single current angle valve, simple in construction, easy to make, low manufacture cost；Using the soft seal of cushion rubber 5, good sealing effect, service life
It is long；Valve body 1 is in 90 degree, thus it is possible to vary the flow direction of fluid, and reverse flow of fluids can be effectively prevented, use is wide.
Described above is only to preferred embodiment of the present utility model, not the utility model is made any formal
Limitation, it is every according to the technical essence of the utility model to any simple modification made for any of the above embodiments, equivalent variations with
Modification, is belonged in the range of technical solutions of the utility model.
