Abstract

The utility model discloses a force control valve, which comprises a valve body (1), a valve shaft (4), a large valve plate (2), a discharge port (7) on the large valve plate (2), a small valve plate (6), a control cavity (8) and a control rod (10). The centerline of the sealing surface of the large valve plate (2) forms an included angle alpha of 5-35 degrees with the vertical direction, and the central axial line of the control rod (10) forms an included angle beta of 5-60 degrees with the vertical direction. The force control valve with the large diameter can be easily processed on small equipment, occupies small area and can help to improve the force bearing condition of the control rod.

Description

A kind of pipe power valve

Technical field

The utility model relates to a kind of valve, particularly relates to a kind of valve that exit of pump adopts pipe medium pressure control that is installed on.

Background technique

The valve that piston type hydraulic control butterfly valve (Zl200620051093.1) and two kinds of structural types of diaphragm type hydraulic butterfly valve (ZL200620051094.6) are arranged at present, this valve is installed on exit of pump, the control chamber that is arranged at the valve body top is by tilting valve plate in the piston rod component controls valve bodies such as (lifting bars), by being combined under the effect of pipe network medium of large and small valve plate and control chamber, realization the slow of valve opened and Slow Close.Its structural feature is: control chamber and the rod member (piston rod or lifting bar) of controlling large and small valve plate vertically are installed on the valve body top, by the tilting design of valve plate than wide-angle, improve the rod member stressing conditions.At valve aperture hour, this structure is rationally feasible.But because valve must be clamped in horizontal position with valve seat adding man-hour, promptly on machine table, valve seat is smoothed by grade bar, therefore the grade bar of wide-angle has increased the valve body turning radius, has seriously taken machine tool, is unfavorable for the production and the popularization of this structure valve in the heavy caliber field.

The model utility content

Technical problem to be solved in the utility model provides a kind ofly to be convenient to process larger caliber, to take up an area of less, as to improve control rod member force-bearing situation pipe power valve on more small-sized equipment.

In order to solve the problems of the technologies described above, the pipe power valve that the utility model provides, comprise valve body, the top of valve body is provided with control chamber, control chamber links to each other with outlet with the import of valve body with outlet bypass pipe fitting by import bypass pipe fitting respectively, big valve plate is installed in the valve body by valve shaft, the one end hinge of little valve plate handle is loaded on the valve shaft, the other end has little valve plate and hinged by the controlling rod of connecting rod and control chamber, the corresponding sealing of discharge orifice of offering on little valve plate and the big valve plate, the sealing surface center line of big valve plate and the angle α of vertical direction are 5-35 °, and the angle β of the medial axis of controlling rod and vertical direction is 5-60 °.

The sealing surface center line of described big valve plate and the angle α of vertical direction are 20 °; The angle β of described control chamber medial axis and vertical direction is 35 °.

Described control chamber can adopt piston type and two kinds of structures of diaphragm type, its principle unanimity.

Adopt the pipe power valve of technique scheme,, help the valve of processing larger caliber on more small-sized equipment, reduce the equipment input cost, further improve the force-bearing situation of controlling rod simultaneously by the tilting included angle that reduces the main valve valve seat of control chamber.

In sum, the utility model is a kind ofly to be convenient to process larger caliber on more small-sized equipment, to take up an area of less, as to help improving control rod member force-bearing situation pipe power valve.

Fig. 2 is a piston type pipe power valve arrangement schematic representation.

Embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Referring to Fig. 1, the top of valve body 1 is provided with diaphragm type control chamber 8, diaphragm type control chamber 8 links to each other with outlet 13 with the import 12 of valve body 1 with outlet bypass pipe fitting 9 by import bypass pipe fitting 3 respectively, big valve plate 2 is installed in the valve body 1 by valve shaft 4, the one end hinge of little valve plate handle 5 is loaded on the valve shaft 4, the other end has little valve plate 6 and hinged with the controlling rod 10 of diaphragm type control chamber 8 by connecting rod 11, the discharge orifice 7 corresponding sealings of offering on little valve plate 6 and the big valve plate 2, the sealing surface center line of big valve plate 2 and the angle α of vertical direction are 5-35 °, best angle is 20 °, the medial axis of the controlling rod 10 of diaphragm type control chamber 8 and the angle β of vertical direction are 5-60 °, and best angle is 35 °.

Referring to Fig. 2, control chamber adopts piston type control chamber 14, its principle unanimity.

Controlling rod 10 is not limited to above-mentioned form with being connected of little valve plate handle 5, as long as can promote and little valve plate handle 5 keyings of pull-up.

Claims

1. manage the power valve for one kind, comprise valve body (1), valve shaft (4), big valve plate (2), be opened in the discharge orifice (7) on the big valve plate (2), little valve plate (6), control chamber, controlling rod (10), it is characterized in that: the sealing surface center line of described big valve plate (2) and the angle α of vertical direction are 5-35 °, and the medial axis of described controlling rod (10) and the angle β of vertical direction are 5-60 °.
