Abstract
The utility model discloses a drain valve with a novel sealing device, and belongs to a valve. The problems that a seal of a traditional sealing device of a drain valve can be easily damaged, airtightness is poor, and maintenance and repair are difficult are solved. The drain valve mainly comprises a valve body with a channel, a bonnet, a valve plate, a buoy assembly, a plug screw and a plug, wherein a sealing gasket is arranged between the valve body and the bonnet, the valve body, the bonnet and the sealing gasket are fixedly connected through a first screw, the valve plate is arranged on the upper portion of the valve body, the valve plate and the buoy assembly are fixedly connected through a fastening bolt, the bonnet is connected with a valve seat through a second screw, an exhaust opening in the valve seat protrudes out and exposes a protruding surface, and the protruding surface is a horizontal sealing surface. According to the drain valve with the novel sealing device, the sealing mode that two horizontal planes are combined is adopted, sealing performance is good, maintenance is convenient, and the drain valve has a certain practical value and the application prospect.
Description
Technical field
The utility model relates to a kind of valve, specifically, relates in particular to a kind of drain valve with new type sealing device.
Background technique
What tradition drain valve adopted is that the mode that combines of lever construction and taper valve is as seal arrangement.In use, often and valve seat friction, surface of contact is easy to impaired taper valve, once the impaired sealing of surface of contact will be not tight, now necessary replacing taper valve, and the taper valve of changing must fit like a glove, also brings very big inconvenience to maintenance service.In addition, adopt lever construction, equally also can cause taper valve and valve seat to coordinate not tight phenomenon, sealability is poor.
Summary of the invention
The utility model discloses a kind of drain valve with new type sealing device, for solving the sealed mouth rapid wear of traditional drain valve seal arrangement, the problem that poorly sealed and maintenance service is difficult.
The utility model is achieved through the following technical solutions:
With the drain valve of new type sealing device, comprise valve body, valve gap, valve block, float component, plug screw, obstruction with passage, between described valve body and valve gap, be provided with gasket seal, between valve body, valve gap, gasket seal, be fixedly connected with by screw first, described valve body top is provided with valve block, and valve block is fixed and is connected by clamping bolt with float component, described valve gap is connected with valve seat by screw second, relief opening on described valve seat protrudes, and exposes projecting surface, and described projecting surface is horizontal seal face.
The diameter of described valve block is greater than the internal diameter of valve body.
Between described valve gap and valve seat, be provided with valve seat pad.
The protrusion height of the relief opening projecting surface on described valve seat is 2-4mm.
The protrusion height of the relief opening projecting surface on described valve seat is 3mm.
Compared with prior art, the beneficial effects of the utility model are:
1. the utility model adopts the sealing means that two horizontal planes combine, wear and tear very little, and good seal performance;
2. the utility model M R is convenient, only needs to change valve seat after long-term use;
3. the utility model is simple in structure, is easy to manufacture, and only need on the basis of traditional drain valve, change slightly.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present utility model.
In figure: 1, valve body; 2, valve gap; 3, valve block; 4, float component; 5, plug screw; 6, gasket seal; 7. screw first; 8. valve seat pad; 9. screw second; 10. valve seat; 11. projecting surfaces; 12. stop up.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated:
With the drain valve of new type sealing device, comprise valve body 1, valve gap 2, valve block 3, float component 4, plug screw 5, obstruction 12 with passage, between described valve body 1 and valve gap 2, be provided with gasket seal 6, between valve body 1, valve gap 2, gasket seal 6, be fixedly connected with by screw first 7, described valve body 1 top is provided with valve block 3, valve block 3 is fixed and is connected by clamping bolt 12 with float component 4, described valve gap 2 is connected with valve seat 10 by screw second 9, relief opening on described valve seat 10 protrudes, expose projecting surface 11, described projecting surface 11 is horizontal seal face.
The diameter of described valve block 3 is greater than the internal diameter of valve body 1.
Between described valve gap 2 and valve seat 10, be provided with valve seat pad 8.
The protrusion height of the relief opening projecting surface 11 on described valve seat 10 is 2-4mm.
The protrusion height of the relief opening projecting surface 11 on described valve seat 10 is 3mm.
When medium enters after valve body 1, the pressure of medium is higher than external pressure, and the pressure reduction producing can drive pontoon combination part 4 to move upward, and the rising band moving valve plate 3 of pontoon combination part 4 rises, valve block 3 planes contact with valve seat 10 planes, just can realize good sealing effect under the active force of pressure reduction.
In sum, it is only preferred embodiment of the present utility model, not be used for limiting the scope that the utility model is implemented, all equalizations of doing according to the shape described in the utility model claim scope, structure, feature and spirit change and modify, and all should be included within the scope of claim of the present utility model.
