Abstract
The utility model relates to a ball valve with a buffer layer and mainly aims at solving the problems that an existing ball valve is poor in pressure receiving capacity and valve sealing performance. The valve is characterized in that a buffer structure is arranged between a valve body and a ball body, the buffer structure is in a net shape, the valve body is provided with a water outlet and a water inlet, and the periphery of the water outlet and the periphery of the water inlet are all sleeved with rubber layers. The ball valve with the buffer layer has the advantages of being good in anti-pressure ability, and good in sealing performance. Moreover, after the ball valve is impacted by high pressure liquid for a long time, the conditions of deformation and leakage can not occur.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of ball valve with buffer layer.
Background technique
Existing ball valve on market, its sealing is to realize by the ball face sealing circle of spheroid and sphere-contact, after ball valve work a period of time, can wear and tear in the contacting point of spheroid and ball valve, spherome surface is subject to the impulse force of highly pressurised liquid for a long time, and spheroid is deformed, and has loosening, thereby cause ball valve to leak, affect ball valve and work normally.And common ball valve sealing effect effect is undesirable, can greatly reduce like this life-span that ball valve uses.
Summary of the invention
In order to overcome the deficiency of background technique, the utility model provides a kind of ball valve with buffer layer, mainly solved the problem of the weak valve seal poor performance of existing ball valve compression capability, this ball valve anti-pressure ability is good, good seal performance, can keep ball valve after being subjected to for a long time the highly pressurised liquid impulse force, can not deform, the situation of leakage.
The technological scheme that the utility model adopts is: a kind of ball valve with buffer layer, comprise valve body, spheroid, valve rod, valve gap, operating structure, be provided with one deck buffer structure between valve body and spheroid, described buffer structure is netted, and described valve body is provided with water outlet and water inlet, and described water outlet and water inlet four sides all are enclosed with rubber layer.
Described buffer structure is equilateral triangle net like structure.
The thickness of described buffer structure is 1/2nd of spheroid thickness.
The beneficial effects of the utility model are: owing to taking technique scheme, effectively improved spheroid after the impulse force that is subject to for a long time highly pressurised liquid, the ability that can not deform.Can not cause becoming flexible after using for a long time, strengthen the sealability of spheroid and valve body, can not produce leakage.
Description of drawings
Fig. 1 is structural representation of the present utility model.
1-valve body in figure, 2-spheroid, 3-valve rod, 4-valve gap, 5-operating structure, 6-buffer structure, 7-water outlet, 8-water inlet, 9-rubber layer.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As shown in Figure 1, a kind of ball valve with buffer layer, comprise valve body 1, spheroid 2, valve rod 3, valve gap 4, operating structure 5 is provided with one deck buffer structure 6 between valve body 1 and spheroid 2, and described buffer structure 6 is netted, described valve body 1 is provided with water outlet 7 and water inlet 8, and described water outlet 7 and water inlet 8 four sides all are enclosed with rubber layer 9.Before driving valve, spheroid 2 can be subjected to the impulse force of highly pressurised liquid, and the buffer structure 6 between valve body 1 and spheroid 2 can reduce the pressure that spheroid 2 is subject to, and can be out of shape thereby reduced spheroid 2, causes the situation of leak of liquid to occur.After driving valve, because valve body 1 is provided with water outlet 7 and water inlet 8, water outlet 7 and water inlet 8 four sides all are enclosed with rubber layer 9, make the compact type of valve body 1 and spheroid 2 better.After liquid communication, can not leak, reduce the waste of resource.
Described buffer structure 6 is equilateral triangle net like structure.Equilateral triangle is the best shape of stability, when spheroid 2 is subject to the impact of high pressure, has better alleviated the suffered pressure of spheroid 2.
The thickness of described buffer structure 6 is 1/2nd of spheroid 2 thickness.Reduced like this cost of production.
Every technician's notice: although the utility model describes according to above-mentioned embodiment; but invention thought of the present utility model is not limited in this model utility; the repacking of any utilization inventive concept all will be included in this patent scope of patent protection.
