Abstract
A novel sealing cup comprises a spring, a cup cover, a bonnet, a big sealing gasket, a small sealing gasket, a valve core and a cup body, wherein the cup cover is connected with the cup body with multi-step screw threads, and the big sealing gasket arranged between the cup body and the cup cover can seal the cup effectively after being tightened. The cup cover assumes a shape of cylinder, a ring groove is arranged in the cup cover for arranging the big sealing gasket, and a stepped hole is arranged in the center of the cup cover. A valve cover assumes a shape of cylinder, a thread hole is provided in the center of one end surface. The valve core assumes a shape of stepped round bench, the small end is provided with threads, and the valve core is inserted into the center hole of the cup cover after being lined the small sealing gasket. The bonnet against the spring is connected with the valve core threads and cooperated with the gap of the center hole, and can move up and down. The valve core, the small sealing gasket and the cup cover are in a compact condition under the action of the spring, when the sum of the pressure in the cup and the spring force is smaller than the outside atmosphere pressure, the outside atmosphere pressure up-opens the valve core automatically and controls the pressure difference in a determined range. If inflicting a force for overcoming the spring on the top of the bonnet with the finger, the valve core moves downward and loosens the small sealing gasket, the pressure difference is disappeared immediately, and the user can open the cup cover gently.
Description
Affiliated technical field
The utility model relates to a kind of novel seal cup.
Background technology
At present, often along with the slow decline of water in the cup temperature, cup external and internal pressure difference just can increase known seal cup gradually, and the temperature difference is big more, and its pressure differential is also big more, so it is just hard more to turn on bowl cover, certainly will make troubles to the user.
Summary of the invention
Cause the problem of opening difficulty because of pressure is excessive in order to solve seal cup, the utility model provides a kind of and cup external and internal pressure difference can be controlled in certain scope, and expert's dynamic balancing pressure, easily turns on the novel seal cup of bowl cover.
The technical scheme that its technical problem that solves the utility model adopts is: bowl cover is the same with traditional seal cup with structure between cup, adopts multiple thread to connect, the big sealing gasket of middle lining.It is cylindric that bowl cover is, outside smooth, and inner recess is established the ring groove that big sealing gasket is installed, and shoulder hole is established at the center, and the big end in aperture outwardly.It is cylindric that bonnet is, and screwed hole is established at the center of an end face, the screw thread bowl cover central stepped of inwardly packing into, and external diameter cooperates with the bore clearance of the big end in aperture.It is round table-like that spool is ladder, and small end is established screw thread, and lining inserts centre bore after going into little sealing gasket in bowl cover, be inserted in spring again and be threaded with bonnet, external diameter and bowl cover centre bore matched in clearance.Spool, little sealing gasket, bowl cover are owing to be subjected to the effect of spring force to be in compact state each other; When cup internal pressure and spring force sum during less than external atmosphere pressure, ambient pressure just backs down spool automatically.Utilize this dynamic balancer, can guarantee that cup external and internal pressure difference smaller or equal to spring force, increases the sealing property that spring force can improve valve.If will open bowl cover, as long as press...with one's finger bonnet, spool is moved down unclamp little sealing gasket, air-flow is connected from the slit, and pressure obtains balance at once.
The beneficial effects of the utility model are, seal cup are controlled in the scope of certain pressure difference, and expert's dynamic balancing pressure, easily turn on bowl cover.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structure cutaway view of the present utility model
Among the figure 1, spring, 2, bowl cover, 3, bonnet, 4, big sealing gasket, 5, little sealing gasket, 6, spool, 7, cup.
The specific embodiment
Bowl cover [2] adopts multiple thread to be connected with cup [7] in the drawings, can effectively seal after the middle big sealing gasket of lining [4] makes it to tighten.Bowl cover [2] is cylindric, and is outside smooth, and inner recess is established the ring groove that big sealing gasket [4] is installed, and the center is provided with shoulder hole, and the big end in aperture outwardly.Bonnet [3] is cylindric, and screwed hole is established at the center of an end face.It is round table-like that spool [6] is ladder, and small end is established screw thread, and lining is gone into little sealing gasket [5] back from the inboard centre bore that inserts of bowl cover [2], bonnet [3] is supporting spring [1] and is packing into from the big nose end of bowl cover [2], bonnet [3] is threaded with spool [6], and external diameter and bowl cover [2] centre bore matched in clearance can move up and down.Spool [6], little sealing gasket [5], bowl cover [2] are owing to be subjected to the effect of spring [1] to be in compact state each other; Along with decrease of temperature in the cup, cup external and internal pressure difference increases gradually, and when cup internal pressure and spring force sum during less than external atmosphere pressure, ambient pressure just backs down spool [6] automatically, and pressure differential is controlled in certain scope.If impose the power that can overcome spring [1] with finger on bonnet [3] top, spool [6] is moved down unclamp little sealing gasket [5], pressure differential disappears at once.
Claims (1)
1, a kind of novel seal cup, form by spring, bowl cover, bonnet, big sealing gasket, little sealing gasket, spool, cup, bowl cover adopts multiple thread to be connected with cup, the big sealing gasket of middle lining, it is characterized in that: bowl cover is cylindric, in establish the ring groove that big sealing gasket is installed, shoulder hole is established at the center, the big end in aperture outwardly; It is cylindric that bonnet is, and screwed hole is established at the center of an end face; It is round table-like that spool is ladder, and small end is established screw thread, and lining inserts the bowl cover centre bore after going into little sealing gasket, and bonnet is supporting spring and is being threaded with spool, and with the centre bore matched in clearance, can move up and down; Spool, little sealing gasket, bowl cover are subjected to the effect of spring to be in compact state each other.
