Description
Technical field
The utility model relates to valve and makes a kind of pressure valve in industry, especially relates to a kind of pressure valve of adjustable pressure.
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, this pressure valve can only be controlled a kind of pressure when in use, when when pressure need to change, need to adopt the pressure valve that other force value is different, to cause like this cost to increase, and need to again change, inconvenient operation, impracticable.
Summary of the invention
Technical problem to be solved in the utility model is to provide the pressure valve of change pressure value in a kind of situation that can not change pressure valve and easy to operate adjustable pressure.
The technical scheme in the invention for solving the technical problem is: a kind of pressure valve of adjustable pressure, comprise valve seat and valve gap, described valve gap is arranged on valve seat, in the inner fluid passage that forms of valve seat, described valve gap side is provided with weep hole, on the valve seat on described side, fluid passage, be arranged with two the first travel limits bars, on valve seat, be provided with the first arcuation chute of L-type, first arcuation chute one end sealing, on the first travel limits bar, be provided with valve plate units, described valve plate units comprises valve disc body, the arc-shaped slot turning an angle for valve disc on valve disc body circumference, the pressure port at valve disc body center, the travel limits bar that pressure port both sides correspondence is provided with, the arcuation chute of the L-type that valve disc body is provided with, the sealing of arcuation chute one end, on the cylinder of valve disc body, be fixed with the baffle plate coordinating with arcuation chute, described valve plate units is provided with capping, and capping top is fixed with a dwang, and capping is provided with the second baffle coordinating with arc chute in valve plate units, and described dwang is provided with handwheel.
Further concrete, described valve plate units has one at least.
Further concrete, described valve plate units is two.
Further concrete, described valve disc body and capping are provided with seal ring.
The beneficial effects of the utility model are: after having adopted said structure, by rotation dwang, can will between valve plate units, mutually combine or separate, by the connection increasing between valve plate units, with this, regulate force value, easy to operate, during change pressure value, do not need to change pressure valve, saved fund.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
A kind of pressure valve of adjustable pressure as shown in Figure 1, comprise valve seat 1 and valve gap 2, described valve gap 2 is arranged on valve seat 1, in the inner fluid passage 10 that forms of valve seat 1, described valve gap 2 sides are provided with weep hole 6, on the valve seat 1 on described 10 sides, fluid passage, be arranged with two the first travel limits bars 8, on valve seat 1, be provided with the first arcuation chute 9 of L-type, first arcuation chute 9 one end sealings, on the first travel limits bar 8, be provided with valve plate units 11, described valve plate units 11 comprises valve disc body 111, the arc-shaped slot 114 turning an angle for valve disc on valve disc body 111 circumference, the pressure port 112 at valve disc body 111 centers, the travel limits bar 113 that pressure port 112 both sides correspondences are provided with, the arcuation chute 116 of the L-type that valve disc body 111 is provided with, the 116 one end sealings of arcuation chute, on the cylinder of valve disc body 111, be fixed with the baffle plate 115 coordinating with arcuation chute 116, described valve plate units 11 is provided with capping 2, and capping 2 tops are fixed with a dwang 4, and capping 2 is provided with the second baffle 7 coordinating with arc chute 116 in valve plate units 11, and described dwang 4 is provided with handwheel 5, described valve plate units 11 is two, described valve disc body 111 and capping 2 are provided with seal ring.
When using, first, whole pressure valve, in closed state, is rotated handwheel 5, and handwheel 5 drives dwang 4 to rotate, dwang 4 drives capping 2 to rotate, capping 2 is rotated, and the arcuation chute 116 of its second baffle 7 valve plate units 11 skids off, and no longer combines closely with valve plate units 11, at this moment water flowing can, by capping 2 jack-up, can complete water outlet operation as long as the pressure of water has overcome the pressure of capping 2, when the larger pressure of needs, handwheel 5 is rotated further, capping 2 turns in the time of can not rotating, capping 2 drives valve disc body 111 to rotate, baffle plate 115 on valve disc body 111 from arc chute 116 out, no longer fit with other valve disc body 111, when being discharged into required force value, now rotate backward handwheel 5, valve disc body 111 and capping 2 through just now discharging combine again, only stay the valve disc body 111 of a required force value to discharge, now pass into water, after the pressure of current reaches required force value, jack-up valve disc body 111, reach outlet effect.
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.
