Abstract
The utility model discloses a hydraulic control valve which comprises a valve body. An inlet end is arranged on one side of the valve body, an outlet end is arranged on the other side of the valve body, a control cavity is formed in the upper end of the valve body, a valve cover is arranged at the top end of the control cavity, and the valve body is connected with the valve cover through bolts. A membrane pressing plate of a concave cavity structure is arranged in the upper valve body of the valve body, the space between the membrane pressing plate and the upper valve body forms a spring cavity, springs are arranged in the spring cavity, and a membrane pressing sleeve used for limiting displacement of the valve cover is arranged on the outer circle of a guiding sleeve at the bottom end of the valve cover in a matched mode. The hydraulic control valve is simple in structure, the layout design of the internal structure effectively reduces occupied space, and the hydraulic control valve has the advantages of being large in flow, low in pressure loss and capable of saving energy and protecting the environment.
Description
Technical field
The utility model relates to valve technology field, is specifically related to a kind of hydraulic control valve.
Background technique
Hydraulic control valve is exactly the valve by hydraulic pressure control, is comprised of a main valve and the Dao Guan ﹑ Dao Fa ﹑ Zhen Fa ﹑ ball valve of setting up and pressure gauge etc.According to the difference in application target, function and place, can develop into the floating ball valve ﹑ of distant control subtracts and presses slow safety check ﹑ stream amount control valve ﹑ processed that closes of valve ﹑ to let out pressure valve ﹑ hydro electric brake control valve, control valve for water pump etc.Due to the restriction of Environmental Conditions, hydraulic control valve of the prior art usually exist take up room large, complex structure heaviness, the effectively defect of pilot pressure loss ratio etc.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of simple in structure, the volume that takes up space is little, flow is large, the pressure loss is little hydraulic control valve is provided.
A kind of hydraulic control valve, comprise valve body, and described valve body one side is provided with entrance point, and opposite side is provided with outlet end, and described valve body upper end is provided with control chamber, and the control chamber top is provided with valve gap, and valve body is connected with valve gap by bolt; In the upper valve body of described valve body, be provided with the diaphragm pressing plate that is the matrix cavity structure, space between diaphragm pressing plate and upper valve body forms spring chamber, in spring chamber, be provided with spring, the cooperation of guide sleeve cylindrical place, described valve gap bottom is provided with the diaphragm gland for the limiting valve cap displacement.
The lower valve body place of described valve body is provided with the convex table type sealing surface.
The lower valve body place of described valve body is provided with the stem guiding cover.
The utility model is simple in structure, and the layout design of internal structure has effectively reduced the volume that takes up space, and has that flow is large, the pressure loss is little, the advantage of energy-conserving and environment-protective.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with specific embodiment, the present invention will be further described.Should be understood that following examples are only be used to the present invention is described but not be used to limiting the scope of the invention.
Referring to Fig. 1, a kind of hydraulic control valve that the utility model provides, comprise valve body 1, described valve body 1 one sides are provided with entrance point 2, and opposite side is provided with outlet end 3, and described valve body 1 upper end is provided with control chamber 4, control chamber 4 tops are provided with valve gap 5, and valve body 1 is connected with valve gap 5 by bolt 6; In the upper valve body of described valve body 1, be provided with the diaphragm pressing plate 7 that is the matrix cavity structure, space between diaphragm pressing plate 7 and upper valve body forms spring chamber, in 8 spring chambers 8, be provided with spring 9, adopt this kind design, greatly alleviated original valve disc, the weight that sealing clamp is solid, just reduce the loss of pressure in pipeline naturally; Described valve gap 5 guide sleeve cylindrical places, bottom coordinate and are provided with diaphragm gland 10, the valve gap bottom are carried out spacing, make the open degree of valve become large, thereby make the valve opening flow become large, also make the valve smaller volume simultaneously, and outward appearance is light and handy, reaches the energy-conserving and environment-protective effect.
The lower valve body place of described valve body 1 is provided with convex table type sealing surface 11, replaced the valve seat of original employing to seal, seal ring makes 12 use rubber carry out soft seal, sealing reliability is high, alleviated the weight of valve body, thereby can reach energy-conserving and environment-protective, this valve body design has had more stem guiding cover 13 than original valve body, the valve body navigation designing has replaced originally with valve seat, leading.The aforementioned body structural design, determined the face shaping feature of this main valve, because this main valve internal structure is light and handy, rationally uses, and the transition of external form contour smoothing, thus make main valve weight reduce, take up space little, convenient for installation and maintenance.
