Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
Referring to accompanying drawing: described mortar pump valve comprises actuator 1, valve core valve stem 3 and valve body 5; The spool of valve core valve stem 3 is arranged in valve body 5 by end casing 2, and actuator 1 is connected with the valve rod of valve core valve stem 3; Valve core through hole 1 and valve core through hole 27 are set on the spool of valve core valve stem 3, valve hole 1 and valve hole 28 are set on the wall of valve body 5 accordingly in pairs; The outer surface of the spool of described valve core valve stem 3 arranges tapering along its axial direction, and valve body 5 also arranges identical tapering with the inwall of the spool combination of valve core valve stem 3, between one end that the valve core diameter of valve core valve stem 3 is large and adjacent end casing 2, Compress Spring 10 is installed.
Described valve core through hole 1 and valve core through hole 27 are long oval hole.
Described tapering is 3-15 degree.
At least three seal rings 6 are installed on the spool of described valve core valve stem 3.
Described actuator 1 is the drive unit of machinery, pneumatic, electronic or hydraulic pressure.
In following examples, take the mortar pump valve of two passages as example, in actual applications, can be made into multichannel mortar pump valve.
Embodiment 1:
The spool of the valve core valve stem 3 of mortar pump valve is arranged in valve body 5 by end casing 2, and actuator 1 is connected with the valve rod of valve core valve stem 3; Valve core through hole 1 and valve core through hole 27 are set on the spool of valve core valve stem 3, valve hole 1 and valve hole 28 are set on the wall of valve body 5 accordingly in pairs; The outer surface of the spool of described valve core valve stem 3 arranges tapering along its axial direction, and valve body 5 also arranges identical tapering with the inwall of the spool combination of valve core valve stem 3, between one end that the valve core diameter of valve core valve stem 3 is large and adjacent end casing 2, Compress Spring 10 is installed.Tapering is 10 degree.Actuator 1 is pneumatic drive unit.
Embodiment 2:
On embodiment 1 basis, valve core through hole 1 and valve core through hole 27 are long oval hole.Be set to long oval hole and be cross-section area in order to guarantee material channel unaffected in compensation process.
On embodiment 1,2 basis, three seal rings 6 are installed on the spool of valve core valve stem 3 respectively.Install after seal ring 6, between spool and valve body 5, suitable micro-gap can be set, the wearing and tearing in early stage be mainly the wearing and tearing of seal ring 6, can further extend the working life of mortar pump valve.
In above embodiment, actuator's 1 rotation gyration is positive and negative 90 degree.
Working principle:
In the time that the spool of valve core valve stem 3 and/or valve body 5 wear and tear, or, in the time that the seal ring 6 on the spool of valve core valve stem 3 and/or valve body 5 wear and tear, the spool of valve core valve stem 3 is under the effect of Compress Spring 10, descending in the orientation shown in Fig. 1, the valve core through hole 1 of long oval shape and valve core through hole 27 are also thereupon descending.After long oval hole is descending, still can guarantee the cross-section area of material channel, not affect working efficiency.
