Abstract

The utility model relates to a hydraulic control valve, the characteristic of which lies in that: membrane supporting is provided in the upper and lower valve, membrane is fixed between valves, control cavity is formed by space between membrane and upper valve, spring cavity with spring is formed by space between membrane supporting and lower valve. Control cavity and spring cavity are formed by separation with application of membrane and membrane supporting in this utility model, guiding object is arranged in the valve, which therefore forms shaft flow structure. As a result, phenomenon including turbulence, cavitations and vibration seldom occurs and accurate control can be realized with huge pressure difference between valves.

Description

A kind of hydraulic control valve
Technical field:
The utility model relates to the technical field of hydraulic control valve, specifically a kind of shaft flow structure hydraulic control valve that has soft seal.
Background technique:
Traditional hydraulic control valve generally belongs to the stop valve structure form of non-axial flow, has following shortcoming: 1, complex structure, volume is big, manufacture cost is high, dismounting maintenance inconvenient; When 2, pressure reduction is big after and before the valve, easily produce turbulent flow, cavitate, utter long and high-pitched sounds, the chatter phenomenon; Degree of regulation was poor when 3, pressure reduction was big before and after the valve, the control insufficient sensitivity.
Summary of the invention:
The purpose of this utility model is to provide a kind of improved hydraulic control valve, and it can overcome complex structure in the prior art, difficult, the relatively poor some shortcomings of control accuracy of dismounting maintenance.
To achieve these goals, the technical solution of the utility model is: a kind of hydraulic control valve, it mainly comprises upper and lower valve body, be located at the valve seat in the upper and lower valve body, it is characterized in that: be provided with diaphragm support in the upper and lower valve body, be provided with diaphragm between diaphragm support and the upper valve body, the space between diaphragm and the upper valve body forms control chamber, space between diaphragm support and the following valve body forms spring chamber, is provided with spring part in the spring chamber.
Diaphragm of the present utility model and diaphragm support are divided into control chamber and spring chamber with valve inner during use, be provided with deflector in the valve body, form shaft flow structure, be difficult for producing turbulent flow, cavitation erosion and chatter phenomenon during work, can when big pressure reduction after and before the valve, realize accurately control.
Description of drawings:
Fig. 1 is the utility model one embodiment's a structural representation
Fig. 2 is the another embodiment's of the utility model a structural representation
Embodiment:
The utility model will be further described below in conjunction with drawings and Examples.
The utility model mainly comprises upper and lower valve body 8,6, be located at the valve seat 7 in the upper and lower valve body, it is characterized in that: be provided with diaphragm support 3 in the upper and lower valve body, be provided with diaphragm 9 between diaphragm support and the upper valve body, space between diaphragm and the upper valve body 8 forms control chamber 11, space between diaphragm support and the following valve body forms spring chamber 12, is provided with spring 4 in the spring chamber.Be provided with deflector 5 between diaphragm support and the following valve body 6, deflector is fixedlyed connected with valve seat.One side of upper valve body is provided with pod apertures 1, and an end of pod apertures 1 is connected with control chamber, and the other end of pod apertures 1 is connected with conduit 10; One side of following valve body is provided with pod apertures 2, and an end of pod apertures 2 is connected with spring chamber, and the other end of pod apertures 2 links to each other with conduit.Upper and lower valve body is a metal material, is shaped as column or taper.
In force, diaphragm is installed between upper valve body and the diaphragm support, and the edge part fixed installation must not be moved, and when induction pressure enters between upper valve body and the diaphragm, forms control chamber between upper valve body and the diaphragm.Spring through accurate Calculation is installed in the spring chamber, and certain pre compressed magnitude is arranged after the installation.On the pod apertures 1 conduit is installed, conduit is connected with pilot valve, on pod apertures 2 conduit is installed, and conduit is connected with the external world as required.When control chamber and the increase of spring chamber pressure reduction, diaphragm support is to moving near the deflector direction, and the valve opening trend reduces; When control chamber and spring chamber pressure reduction reduced, diaphragm support was to moving away from the deflector direction, and the valve opening trend increases, and realizes whole control.
