Description of the drawings
The perspective exploded view of Fig. 1, the utility model；
The body portion schematic cross-sectional view of Fig. 2, the utility model；
The stereoscopic schematic diagram of Fig. 3, the utility model rotary spool；
The whole lateral schematic cross-sectional view of Fig. 4, the utility model.
Specific embodiment
The utility model is further described below in conjunction with the accompanying drawings.
As shown in Figures 1 to 4, a kind of plug valve includes the valve body 1 of a top trepanning, a rotary spool in valve body 1
2, the generally cylinder of rotary spool 2, the upper end is equipped with sealing ring 3, and a fixed circlip 31 is pressed on rotary spool 2 and and valve body
1 fixes;1 rotary spool 2 is equipped with a square groove 20, and the circular groove 26 of a placement compression spring 21 is additionally provided in square groove 20；Pressure
Spring 21 withstands a quad seal block 22, and quad seal block 22 is compressed in valve body 1 in square groove 20, and quad seal block 22
Front end camber part 23;20 back side of square groove is a flow channel cavity 24, and flow channel cavity 24 is that a continuous opening surpasses 180 °
Open cavity.
Rotary spool 2 is whole to be packed into valve body 1 from the top trepanning of valve body 1, and 2 overall structure integrated level of rotary spool is high, packet
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 in 27 lower part of valve stem part.
Rotary spool 2 is made of plastics etc., the shaping higher of moulding.Relative to traditional easy processing circle knot
Structure, this square groove 20 have the advantages, 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 rotation, the superposition of tolerance variations or the overlapping of Poor structure, will appear quality problems 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 round 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 advantageous 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 is 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 lead to the unevenness of sealing surface stress, and valve easily leaks.
The valve body 1 of the utility model is horizontal triple valve, is set in horizontal position there are three mesoporous 10.The connection at three ends can be with
It is the connection mode of internal thread, external screw thread, card pressure or other structures.As shown in figure 4, 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 range A of continuous open cavity, this
The 24 continuous opening angle A of flow channel cavity of utility model is not less than 180 °, preferably at 200 ° to 250 °.Therefore the utility model
Quad seal block 22 be one, and unconventional symmetrical structure has the function of more flexible control pipeline flow direction, can be single
It solely realizes the keying of three mesoporous 10, there are different technical-functionalcharacteristics characteristics from existing triple valve.
The valve body valve body 1 of the utility model can also be horizontal two-port valve, be set in horizontal position there are two mesoporous 10, mesoporous
10 can be two mesoporous 10 of 90 degree of patent or level as disclosed in background technology on an axle center.It is rectangular close
Envelope block 22 can realize that the sealing of any mesoporous 10 is closed.
The valve body valve body 1 of utility model can also be horizontal four-way valve, be set in horizontal position there are four mesoporous 10, in four
Hole 10 is into cross distribution, and quad seal block 22 can realize that the sealing of any mesoporous 10 is closed, the flow channel cavity 24 and valve of plug valve
Three connected mesoporous 10 of body 1 communicate.
The plug valve of the utility model can realize valve body in field of air conditioning, building supply heating field, control structure uniqueness
In any mesoporous control, and sealing structure is more reasonable, and accessory is few, and positioning and assembling are simple, and circulation cavity is big, safety with
In cost, the more market competitiveness.
