Abstract
The utility model relates to a multi-position type check valve. The middle part of a valve body is connected with a support frame which is provided with a guide sleeve. An inner cavity of the inlet end of the valve body is fixed with a valve seat body which is provided with a valve seat. A guide sleeve is provided with a valve rod. The valve rod which is provided with a spring is connected with a valve clack. The valve clack and the valve seat are in line contact (cone shape) or surface contact (valve clack plane shape) by the spring force. The utility model has the advantages of simple structure, convenient manufacture, assembly and repair, good sealing effect, long service life, and automatic check.
Description
The utility model relates to valve (F16K), particularly safety check in International Classification of Patents.
In industrial boiler water supply and steam pipe system, safety check is a vitals.93236355.5 having overcome Lift check valve, number patent is difficult to guarantee flap, valve base chamber concentricity and the oversize disadvantage of guide rod.But, this patent structure complexity, valve body and valve gap bolt, so processing and assembling is more loaded down with trivial details.
The purpose of this utility model provides a kind of multi position type safety check.It is simple in structure, and processing, assembling, maintenance are all than being easier to sealing effect ideal and automatic braking.
It is as follows to disclose new technological scheme:
The multi position type safety check comprises valve body, flap, valve seat and guide pin bushing at least, and body cavity middle part coaxial line is associated with the support with guide pin bushing; In the inner chamber of valve body import, coaxial line is fixed with valve seat or with the valve body of valve seat; Valve rod is housed in the guide pin bushing, and with also being associated with flap on the valve rod of spring, the elastic force of spring makes flap and valve seat be that line contacts or the face contact.
By the multi position type safety check sample that such scheme is made, simple in structure, make, assembling, maintenance be easier to, back on probation sealing effect ideal, the life-span is long and can automatic braking.
Accompanying drawing 1 is an embodiment's of the utility model a schematic representation (flap is tapered, contacts with the valve seat line).Accompanying drawing 2 is another embodiment of the utility model, i.e. face contact schematic representation.
Now in conjunction with the accompanying drawings 1, describe embodiment as after.The inner chamber middle part coaxial line of valve body 1 is associated with the support 4 with guide pin bushing 5; In the valve body 1 import inner chamber, coaxial line is fixed with the valve body 9 of valve seat 8 or single valve seat 8; Valve rod 3 is housed in the guide pin bushing 5, also is associated with flap 7 on the valve rod 3 with spring 6, the elastic force of spring 6 makes flap 7 and valve seat 8 be that line contacts or face contact (flap 7 tapers are the line contact, and plane shape is the face contact).Can be around 360.Install arbitrarily.Support 4 has some radial through-flows hole 2, and support 4 is made one with valve body 1, or the split assembling.
When inlet fluid pressure during greater than spring force and fluid backpressure sum, flap 7 is backed down, and fluid flows out from outlet through behind the through flow hole 2 of support 4.Otherwise force flap 7 to withstand valve seat 8 by spring force or fluid backpressure, at this moment, valve closes.As can be seen, this model utility structure tube list is made, assembling, maintenance be than being easier to, and valve rod is difficult for rocking among the figure.
