Abstract
The utility model relates to a pipeline valve, which has main technical characteristics that the pipeline valve comprises a shell, a valve seat, a handle, a valve rod, and a valve core; the shell is provided with liquid inlet channel and a liquid outlet channel which are mutually communicated and are on a same straight line, and a valve rod installing channel which is vertical to the liquid inlet channel and the liquid outlet channel; the handle is arranged on one end of the valve rod. The valve core is spherical, the middle part of the valve core is provided with a through hole, and the top end of the valve core is provided with a drop pit. The end part of the other end of the valve rod is in step-shaped shrinkage, and the size of the shrinkage is proper for being clamped and inserted into the drop pit on the top end of the valve core. The valve seat is spherical, and is provided with a sealing ring. The utility model has the advantages of hard leakage, long service life, etc. The utility model can be widely used in pipelines.
Description
The utility model relates to a kind of control valve unit, particularly relates to a kind of pipeline valve.
At present, the set valve of pipeline be mostly be made of metal comprise assemblies such as following housing, valve rod, handle, spool and valve seat, that part of valve rod that is contained in housing that valve rod is equipped with spool is installed in the passage, and realizes the wall of this passage and the sealing between valve rod by seal ring and clamping nut.This valving in use is prone to following defective: realize switch owing to it adopts spool with respect to the lifting of valve seat, and seal ring is prone to leakage with being that different materials is made between the metal shell, causes waste.
The purpose of this utility model is to provide a kind of difficult leakage and pipeline valve easy to use.
The purpose of this utility model is by providing a kind of valve with following structure to realize, this pipeline valve comprises: housing, valve seat, handle, valve rod, spool, have on the described housing and be interconnected and the liquid inlet and outlet passage on same straight line and vertical with it valve rod are installed passage, described handle is contained in an end of valve rod.Described spool shape spherical in shape, there is a through hole centre, and there is a pit on the top.The stepped retraction in the end of the other end of described valve rod, the size of described retraction is advisable can block in the pit that is inserted in described spool top.Described valve seat shape spherical in shape and seal ring is arranged.
Described spool and housing, valve seat, valve rod all are to be made by the MC nylon material.
Have following advantage after the utility model employing technique scheme:
1, good seal performance is difficult for revealing;
2, long service life, not cracky.
Accompanying drawing 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described, as shown in the figure, rotatable handle 1 drives 2 rotations of coupled valve rod, because the stepped retraction in end of the other end of valve rod 2, and the big I card of retraction is inserted in the pit 3 on spool top, so ball shape spool 4 also and then rotations when a certain angle of valve rod 2 rotations.Valve seat 6 sizes in the housing 5 are slightly larger than spool 4, and the seal ring 7 that is installed in the valve seat 6 can stop up the firmly liquid inlet and outlet passage of housing 5.There is a through hole 8 centre of described spool 4, and when rotatable handle 1 and drive spool 4 when the liquid inlet and outlet passage of through hole 8 and described housing 5 is a straight line substantially, valve is open-minded.And when rotatable handle 1 and drive spool 4 when the liquid inlet and outlet passage of through hole 5 and described housing 5 is square crossing substantially, spool is at the obstruction valve closing of seal ring 7.
In the utility model, spool 4 and housing 5, valve seat 6, valve rod 2 etc. all are to adopt the MC nylon material to make, and make it in use have more elasticity and better running-in ability, prolong its working life widely.
Claims (2)
1, a kind of pipeline valve, mainly comprise: housing, valve seat, handle, valve rod, spool, have on the described housing and be interconnected and liquid inlet and outlet passage on same straight line and vertical with it valve rod installation passage, described handle is contained in an end of valve rod, it is characterized in that described spool shape spherical in shape, there is a through hole centre, there is a pit on the top, the stepped retraction in the end of the other end of described valve rod, the size of described retraction is advisable can block in the pit that is inserted in described spool top, described valve seat shape spherical in shape and seal ring is arranged.
2, a kind of pipeline valve according to claim 1 is characterized in that described spool and housing, valve seat, valve rod all are to be made by the MC nylon material.
