Description

One kind extrudes valve module
Technical field
It is especially a kind of to extrude valve module the present invention relates to flow-control element is matched somebody with somebody in water hydraulic system.
Background technology
Water hydraulic flat valve be in water hydraulic system commonly use match somebody with somebody flow-control element, when the pump is operated with the round fortune of plunger It is dynamic to open and close.Flat valve reduces friction pair (cylinder body and valve plate), so compared with valve plate distribution formula, Flat valve Leakage and the wear problem of valve plate friction pair are avoided, there is good sealing.It can in a high voltage state work, be hydraulic pressure Very attractive structure type in pump.It is strong in low viscosity, corrosivity, contaminatives such as extra large (light) water of pumping, chemicals, sewage The production field such as fluid in, for Flat valve form using quite varied in Water Hydraulic Pump, the performance of flat valve directly affects pump Service life, so suction valve assembly and extrude valve module structure design it is most important.Existing extrusion valve module is hit by a bullet Spring force is excessive, though it can guarantee that valve is closed rapid when starting water suction, causes discharge pressure to increase, efficiency reduces;Spring force Too weak, when suction valve assembly is opened and drainage pipeline unloads, pressure valve can not close, so the structure and precompression pair of spring Extrude valve module has a major impact effect.
The content of the invention
The technical problem to be solved in the present invention is:Based on above mentioned problem, there is provided one kind extrudes valve module.
The technical solution adopted for the present invention to solve the technical problems is:One kind extrude valve module, including valve seat, valve element, Spring base and spring, the valve element are located at the two of valve element respectively through valve seat and the through hole of spring base, the valve seat and spring base End, on valve element, one end of spring is connected on spring base the spring housing, and guide holder, institute are provided with the inside of the valve seat The other end and guide holder for stating spring are offseted, and spring is more than with one end peripheral diameter that guide holder offsets to be connected to one on spring base The peripheral diameter at end.
Further, the both ends of the valve element are respectively fixed with stop nut and clamp nut.
Further, the annular groove of at least one placement O-ring is offered on the outer peripheral face of the valve seat.
Further, the valve seat uses soft-hard cooperation with valve element, and valve seat is using the higher engineering plastics of intensity, valve element Using the higher stainless steel of hardness.
Further, the guide holder uses copper powdered metallurgical material.
The beneficial effects of the invention are as follows:The structure of spring of the present invention can guarantee that the keying for extruding valve module is flexible, structure letter Single, in light weight, inertia is small, easy to assembly, is readily disassembled, and processing cost is low.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the present invention.
In figure:1. valve seat, 2. valve elements, 3. spring bases, 4. springs, 5. loosen nut, 6. clamp nuts, 7. guide holders, 8. Annular groove.
Embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These accompanying drawings are simplified schematic diagram, only with Illustration illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention.
As shown in figure 1, a kind of extrude valve module, including valve seat 1, valve element 2, spring base 3 and spring 4, valve element 2 pass through valve seat 1 and the through hole of spring base 3, valve seat 1 and 4, spring are located at the both ends of valve element 2 respectively, and the both ends of valve element 2 are respectively fixed with locking Nut 5 and clamp nut 6, spring 4 are enclosed on valve element 2, and one end of spring 4 is connected on spring base 3, and the inner side of valve seat 1 is set There is guide holder 7, the other end and the guide holder 7 of spring 4 offset, and spring 4 is more than connection with one end peripheral diameter that guide holder 7 offsets The peripheral diameter of one end on spring base 3.
In addition, the annular groove 8 of at least one placement O-ring is offered on the outer peripheral face of valve seat 1.
Valve seat 1 and valve element 2 use soft-hard cooperation, valve seat 1 using the higher engineering plastics of intensity, valve element 2 using hardness compared with High stainless steel, guide holder 7 use copper powdered metallurgical material.Valve element 2 when the medium-high frequency of guide holder 7 is vibrated, be readily available compared with Small abrasion.Using the higher engineering plastics of intensity, it forms soft or hard material with stainless steel core 2 and matched valve seat 1, be advantageous to relax or Absorb the impact to valve seat 1 when stainless steel valve element 2 is closed.Meanwhile the engineering plastics that intensity is higher, extruding, valve module is high for a long time Frequency has the longer life-span under impacting.
It is complete by above-mentioned description, relevant staff using the above-mentioned desirable embodiment according to the present invention as enlightenment Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention Property scope is not limited to the content on specification, it is necessary to determines its technical scope according to right.
