Embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Like Fig. 1～shown in Figure 2, valve assembly includes before the kitchen range of present embodiment

Valve body 1; Its vertical side is respectively arranged with the first protruding neck 11 of first axis hole and the second protruding neck 12 with second axis hole 121; The first protruding neck 11 and the second protruding neck 12 are 90 degree and are provided with, and the outer wall of the second protruding neck 12 is provided with outside thread; First axis hole and second axis hole 121 can be connected with valve body 1 respectively, valve body therein an end also be connected with realize the joint 1 be connected with other pipelines ';

Spool 2; Present embodiment is a spherical valve core 2; This spool 2 is arranged in the valve body 1 rotationally; Spool 2 is respectively arranged with seal ring 21 in the contacting point of surface, its gateway, rear and front end and valve body 1 passage, and, offer one on the spool 2 when these spool 2 complete openings and the through hole 22 that is connected with first axis hole;

The valve rod (not shown) is arranged in first axis hole, and the two ends of valve rod connect spool 2 and handle 3 respectively, and valve rod can drive spool 2 rotations under the rotation of handle 3, thereby realizes the opening and closing of pipeline;

Connecting head 4, the one of which end has internal thread, and the other end has outside thread, and an end of connecting head 4 and the second protruding neck 12 are through being threaded; The inwall of connecting head 4 is formed with annular protrusion 41; Also being provided with in the second protruding neck 12 can be along these second protruding neck 12 axially movable core bar 5, and core bar 5 includes core print 51 and afterbody 52, wherein; Core print 51 is " worker " font; And this core print 51 is equipped with one by the spacing sealing plug 6 in I-shaped upper and lower end face at medium position, and sealing plug 6 has the conical surface that can be limited on the annular protrusion 41; This conical surface can also play sealing effect; The afterbody of core print 51 is provided with and can drives the spring 7 that this core print 51 offsets with annular protrusion 41 sealing all the time, and an end of spring 7 is arranged at the afterbody of core bar 5, and second axis hole, 121 interior edge faces of the other end of spring 7 and the second protruding neck 12 offset.

Pipeline is when normal the use; Open core bar 5 in order to prevent misoperation; At the other end of the connecting head 4 dustproof end cap 8 that also has been threaded; Should can also play dustproof antifouling effect by dustproof end cap 8, be provided with sealing gasket 81 between dustproof end cap 8 and the connecting head 4, to guarantee the tightness that is connected of dustproof end cap 8 and connecting head 4.

As need carry out pressure measurement to pipeline, like Fig. 3, shown in Figure 4, the end cap 8 that at first will prevent dust takes off; Quick pressure measurement assembly is installed on the connecting head 4; Usually, adopt common Green's pressure measurement assembly to realize quick pressure measurement, this pressure measurement assembly includes pressure measuring tie-in 91, seal ring 92 and nut 93; Wherein, The head of pressure measuring tie-in 91 has an annular boss 911, and seal ring is set in the head of pressure measuring tie-in 91 and offsets with the upper-end surface of annular boss 911, and nut sleeve is located at outside the pressure measuring tie-in 91 and can be threaded with the outside thread realization of connecting head 4 one ends.

During pressure measurement; The head of pressure measuring tie-in 91 can directly insert in the connecting head 4; When the application of force was screwed nut, the head of pressure measuring tie-in 91 slowly entered in the connecting head 4, and the seal ring on the pressure measuring tie-in 91 is tight against mutually with the end face of connecting head 4 and realizes sealing; Core print 51 ends in the head end of pressure measuring tie-in 91 and the second protruding neck 12 offset and extrusion spring 7; Make sealing between the annular convex of sealing plug 6 and connecting head 4 of core bar 5 be separated and form gap A, thereby medium is flowed into through the through hole 22 of spool 2 in the second protruding neck 12 and the connecting head 4 from valve body 1 smoothly, the pressure that pressure measuring tie-in 91 can signal piping;

After accomplishing the pressure measurement read-record; Can unscrew nut extracts pressure measuring tie-in 91; Core bar 5 is rapidly playback under the effect of spring 7 power, and the conical surface that is arranged on the sealing plug 6 on the core print 51 offsets again with the annular protrusion 41 of connecting head 4 and realizes sealing, and pipeline ends.

Can either guarantee can when not closing spool 2, realize the medium proper flow of common valve body 1 the quick pressure measurement of pipeline again, and guarantee the line seal property in the pressure measurement process through the valve assembly structure of present embodiment, simple in structure, easy to use.
