Description
Technical field
The present invention relates to a kind of multistage Decompression valves, belong to valve field.
Background technique
Traditional pressure-relief valve structure is complicated, and generally closed by objects such as bulbs, requirement on machining accuracy is high, and not easily adjusts the flow of Decompression valves with Valve value.
Summary of the invention
The technical problem to be solved in the present invention is: overcome technical problem existing in prior art, provide a kind of Decompression valves that can carry out multistage adjustment.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of multistage Decompression valves, comprise valve body and blockage mechanism, described valve inner is provided with a cylindrical cavity, the upper side wall of described cylindrical cavity is communicated with drain opening, the bottom disc of described cylindrical cavity is communicated with water intake, described bottom disc is provided with the weep hole of ring, the inwall of described drain opening is provided with a tapering type stepped ring forging, described stepped ring forging is arranged by N number of annulus and forms, and the diameter of described annulus diminishes from drain opening gradually to water intake direction;
Described blockage mechanism comprises valve rod and N number of closed plectane, and the diameter of described N-1 closed plectane is greater than the internal diameter of N-1 annulus, and the diameter of described N-1 closed plectane is less than the internal diameter of N number of annulus;
Realize elasticity by N-1 diastole spring between described closed plectane to connect, a valve rod is rotatably connected on the top of N number of closed plectane, described valve rod is flexibly connected with valve body by screw thread with valve body, the mobile axis of described valve rod and the start axis coaxle of diastole spring.
As further innovation of the present invention, the periphery of described closed plectane is provided with seal ring.
As further innovation of the present invention, the elasticity of described N-2 spring is greater than the elasticity of the spring of N-1.
The invention has the beneficial effects as follows:
The present invention realizes closing the multistage of valve by the shut combination of multidisc, sealing effect is relatively good, the multistage spring of this valve is closed and is made to regulate more accurately with sensitive simultaneously, the processing of inventive closure end face is simultaneously processed compared to traditional circular hole, its precision is higher, and sealability is also better.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is generalized section of the present invention;
Fig. 2 is the generalized section of closed plectane.
Wherein 1, valve body; 2, drain opening; 3, water intake; 4, valve rod; 5, annulus; 6, plectane is closed; 7, diastole spring; 8, seal ring.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As shown in Figure 1 and 2, a kind of three grades of formula Decompression valvess, comprise valve body 1 and blockage mechanism, valve body 1 inside is provided with a cylindrical cavity, the upper side wall of cylindrical cavity is communicated with drain opening 2, the bottom disc of cylindrical cavity is communicated with water intake 3, bottom disc is provided with the weep hole of annulus 5 shape, the inwall of drain opening 2 is provided with a tapering type stepped ring forging 5, stepped ring forging 5 forms by 3 annulus 5 are arranged in parallel, and the diameter of annulus 5 diminishes from drain opening 2 gradually to water intake 3 direction; The diameter that blockage mechanism comprises valve rod 4 and 3 closed plectanes the 6,3rd closed plectane 6 is greater than the internal diameter of the 2nd annulus 5, and the diameter of the 3rd closed plectane 6 is less than the internal diameter of the 2nd annulus 5, all the other the like; Close between plectane 6 and realize elasticity connection by 2 diastole springs 7, a valve rod 4 is rotatably connected on the top of the 3rd closed plectane 6, valve rod 4 is flexibly connected with valve body 1 by screw thread with valve body 1, the mobile axis of valve rod 4 and the start axis coaxle of diastole spring 7; The periphery closing plectane 6 is provided with seal ring 8; The elasticity of the 2nd spring is greater than the elasticity of the spring of the 1st.
By rotary valve cover, the number of the closed plectane be pressed on annulus 5 can be changed, thus change the precompression of two springs, when hydrodynamic pressure is higher than pre-pressure of the spring now, the pressure that closed plectane overcomes spring is moved, thus makes valve open, and fluid circulates.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to right.
