Abstract
The utility model relates to a leak-proof pressure valve which comprises a valve seat and a valve cover. The valve cover is installed on the valve seat, a drain hole is formed in the valve cover, a fluid channel is formed in the middle of the valve seat, the upper portion of the fluid channel is conical, trapezoid plug cores are arranged at the conical position of the upper portion of the fluid channel, the number of the trapezoid plug cores is at least two, a pressure spring is arranged between the trapezoid plug core at the topmost end and the top of the valve cover and a connecting piece is arranged between every two adjacent trapezoid plug cores. Due to the fact that the structure provided with the trapezoid plug cores is adopted, after leakage occurs in one plug core, the rest of the plug cores can still be used normally, and the service life of the pressure valve is prolonged.
Description
Technical field
The utility model relates to a kind of valve mechanism in valve manufacturing, especially relates to a kind of leakproof pressure valve.
Background technique
Pressure valve there is not specified pressure Open valve to realize by reaching, existing pressure valve mainly contains valve body, valve gap, valve disc and spring form, in the time of work, water flow pressure reaches required force value and backs down valve disc, valve disc Compress Spring, water is discharged, when force value reduces, valve disc is again blocked the passage in valve seat under the effect of spring, due to the frequent to-and-fro motion of valve disc, make the contact surface abrasion of valve disc and valve seat serious, often there is groove, shorten working life, need frequent worse valve disc, so not only wasted the time, and change frequent.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of leakproof pressure valve that does not need frequently to change and increased working life.
The technical scheme in the invention for solving the technical problem is: a kind of leakproof pressure valve, comprise valve seat and valve gap, described valve gap is arranged on valve seat, described valve gap is provided with weep hole, centre at valve seat is provided with fluid passage, described top, fluid passage is tapered, at upper taper place, fluid passage, be provided with trapezoidal stifled core, at least two, described trapezoidal stifled core, between the trapezoidal stifled core of top and valve gap top, be provided with pressure spring, between the trapezoidal stifled core described in every adjacent two, be provided with link.
Further concrete, described weep hole is positioned at valve gap top or sidepiece.
Further concrete, described link is spring or cylindrical body.
Further concrete, described trapezoidal stifled core is three.
The beneficial effects of the utility model are: after having adopted said structure, and owing to having adopted a plurality of trapezoidal stifled cored structures, can be after a stifled core to leak, remaining can also normally use, and has extended the working life of pressure valve.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model spring connects;
Fig. 2 is the structural representation of the utility model cylinder connection.
In figure: 1, valve seat; 2, valve gap; 3, weep hole; 4, pressure spring; 5, trapezoidal stifled core; 6, spring; 7, fluid passage; 8, cylindrical body.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
A kind of leakproof pressure valve as shown in Figure 1, comprise valve seat 1 and valve gap 2, described valve gap 2 is arranged on valve seat 1, described valve gap 2 is provided with weep hole 3, in the centre of valve seat 1, is provided with fluid passage 7, and described 7 tops, fluid passage are tapered, in fluid passage, 7 upper taper places are provided with trapezoidal stifled core 5, described trapezoidal stifled core 5 is three, between the trapezoidal stifled core 5 of top and valve gap 2 tops, is provided with pressure spring 4, between the trapezoidal stifled core 5 described in every adjacent two, is provided with link; Described weep hole 3 is positioned at valve gap 2 tops or sidepiece; Described link is spring 6 or cylindrical body 8.
Current enter by fluid passage 7, and when the pressure of current reaches unlatching value, current rise trapezoidal stifled core 5, trapezoidal stifled core 5 compression pressure springs 4, current are discharged from weep hole 3, when force value is less than unlatching value, pressure spring 4 pushes back trapezoidal stifled core 5 in fluid passage 7, blocks current.
It is emphasized that: be only preferred embodiment of the present utility model above, not the utility model is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
