Embodiment
The present invention will be further described below in conjunction with the accompanying drawings.
As shown in Figures 1 to 4, a kind of threeway plug valve, includes the valve body 1 of a top perforate, a rotation in valve body 1
Spool 2, the generally cylinder of rotary spool 2, the upper end are equipped with sealing ring 3, a fixed circlip 31 be pressed on rotary spool 2 and with
Valve body 1 is fixed;1 rotary spool 2 is equipped with a square groove 20, and the circular groove of a placement compression spring 21 is additionally provided with square groove 20
26；Compression spring 21 withstands a quad seal block 22, and quad seal block 22 is compressed in valve body 1 in square groove 20, and square close
Seal 22 front end camber part 23 of block;20 back side of square groove is a flow channel cavity 24, and 24 not rounded hole shape of flow channel cavity, is
One continuous opening surpasses 180 ° of open cavities.
Rotary spool 2 is overall to load valve body 1 from the top perforate of valve body 1, and 2 overall structure integrated level of rotary spool is high, bag
The valve stem part 27 coordinated with handle 5 has been included, the sealing annular groove 28 of dress sealing ring 3 is additionally provided with 27 lower part of valve stem part.
Rotary spool 2 is made of plastics etc., the shaping higher of its moulding.Relative to the circular knot of traditional easy processing
Structure, this square groove 20 have the advantages that, first, the quad seal block 22 coordinated with it will not rotational slippage, the stabilization of size
Property is more preferable；Second, the sealing contact surface of bigger can be formed, third, in product sealing detection, quad seal block 22 or valve body 1
Itself is defective, and test is detectable out, and later stage quality problems；And circular seal, factory testing are good, operational process
Middle component rotates, the superpositions of tolerance variations or Poor structure it is overlapping, quality problems occur using the later stage.
20 back side of square groove of rotary spool 2 is a flow channel cavity 24, and 24 not rounded hole shape of flow channel cavity, is one continuous
Opening surpass 180 ° of open cavities.The valve of traditional circular flow channel such as background technology, although circular easy processing, edge compared with
Small acute angle, sharp, in the state of incomplete open, hydro jet acute angle is also easy to produce noise, and pipeline flow resistance is larger.It is open
Formula cavity can reduce flow resistance to greatest extent, and the smoothness of medium in the favourable pipeline in mellow and full edge, reduces noise, as shown in Figure 3
Fillet part 29.
22 front end camber part 23 of quad seal block, is more bonded the globoidal structure of mesoporous 10, realizes sealing.Curved portion
23 areas are divided to be more than the sealing area of mesoporous 10.Quad seal block 22 is rubber material, and hardness is in shore A 55 to shore A
80.22 rear end of quad seal block is equipped with a column part 25, and column part 25 is arranged in compression spring 21.21 one end side of withstanding of compression spring
The face of shape sealing block 22, one end is in the circular groove 26 of rotary spool 2.With respect to notification number 2718341Y's《Elastic slipper rotary plug valve》
Leaf spring, the contact surface bigger of compression spring 21 and quad seal block 22, more uniformly, the fixed structure of this compression spring 21 is not yet for power output
It can deviate, comparatively, offset can cause the inequality of sealing surface stress, and valve easily leaks.
The valve body 1 of the present invention is horizontal triple valve, and three mesoporous 10 are equipped with horizontal level.The connection at three ends can be interior
Screw thread, external screw thread, card are pressed or the connection mode of other structures.As shown in figure 4, threeway plug valve is in the on-state, the stream
Road cavity 24 is communicated with three mesoporous 10 of valve body 1, and is 220 ° in the opening angle scope A of continuous open cavity, this
The continuous opening angle A of flow channel cavity 24 of invention is not less than 180 °, preferably at 200 ° to 250 °.Therefore the present invention's is square close
It is one to seal block 22, and unconventional symmetrical structure, has the function that more flexible control pipeline flow direction, can be implemented separately three
The keying of a mesoporous 10, has different technical-functionalcharacteristics characteristics from existing triple valve.
It is and square close as shown in figure 5, valve body 1 its 10 inner wall of mesoporous of the present invention forms the annular convex ring 11 of enhancing sealing
When sealing the cooperation of block 22, forced area is small, can realize the decrement and sealing effect of bigger, this valve body 1 can use plastic material.
Annular convex ring 11 can be one or shown concentric circles twice.
For a kind of threeway plug valve of the present invention in field of air conditioning, building supply heating field, control structure is unique, can realize
Any control of three mesoporous, compared with the prior art, advantages of compact and light structure is light-weight；Sealing structure is more reasonable, and accessory is few, fixed
Position and assembling are simple, and circulation cavity is big, in safety and cost, the more market competitiveness.
