Preferably, the limited block is welded in the inner wall of the conduit.
Preferably, the axial direction of the conduit is equipped with air inlet pipe.
In addition, the utility model additionally provides a kind of four-way reversing valve, including main valve body, further include above-mentioned any one institute
The pilot valve stated, the pilot valve are connected to the main valve body.
After adopting the above technical scheme, the utility model has the following advantages that：
Sliding block is covered on the upside of the through-hole of valve seat, and refrigerant generates percussion into fashionable by through-hole to sliding block.Pass through limit
Protrusion makes sliding block be impacted by refrigerant and generate the when of being moved along refrigerant approach axis and be limited protrusion the position-limiting action of sliding block
Limitation can not occur to overturn or break away, to solve the problems, such as that sliding block is impacted by refrigerant and is detached from valve seat.Simultaneously as
Limit protrusion is to be recessed by tube wall of conduit itself or constituted in the inner wall welding of conduit or mechanical connection limited block, without to spring
Piece carries out additional processing, therefore simple in structure, reduces the difficulty of processing of reed, also reduces the assembly difficulty of pilot valve.

The limitation of utility model.
Embodiment one
The present embodiment provides a kind of pilot valves, as shown in Figure 1, including conduit 1, attractor 10, iron core 9, valve seat 7 and sliding block
5, valve seat 7 is fixed on the inner wall of conduit 1, and spring 2 is equipped between attractor 10 and iron core 9, is provided on iron core 9 and extends to valve seat
Bracket 3 at 7, sliding block 5 are fixed on bracket 3.Reed 8 is additionally provided on bracket 3, reed 8 discharges elastic potential energy, to push sliding block
5 fitting valve seats 7.Sliding block 5 is pulled by bracket 3, and is bonded on valve seat 7 and is slided, and conduit 1 and valve seat 7 are equipped with to be entered for refrigerant
Through-hole 6, sliding block 5 cover through-hole 6.The inside of conduit 1 is equipped with limit protrusion 41, and limit protrusion 41 is towards sliding block 5.In the present embodiment,
Limit protrusion 41 is made of the tube wall of conduit 1 to the recess of sliding block 5, to be limited to sliding block 5 on the direction that refrigerant enters.Limit convex
The height for playing 41 is 0.8-1.2mm, and the present embodiment is preferably 1mm.
Since sliding block 5 is covered in 6 upside of through-hole of valve seat 7, refrigerant can generate sliding block 5 in impact work by through-hole 6 into fashionable
With.By limit protrusion 41 to the position-limiting action of sliding block 5, sliding block 5 is made to be impacted and be generated along refrigerant approach axis by refrigerant
It is limited protrusion 41 when movement to limit, can not occur to overturn or breaks away, valve is detached from by refrigerant impact to solve sliding block 5
The problem of seat 7.Simultaneously as limit protrusion 41 is made of tube wall of conduit 1 recess itself, there is no need to be carried out to reed 8
Additional processing, thus it is simple in structure, the difficulty of processing of reed 8 is reduced, the assembly difficulty of pilot valve is also reduced.
Embodiment two
What is different from the first embodiment is that in the present embodiment, limit protrusion is made of the present embodiment limited block 42.Limited block 42
It is connected to the inner wall of conduit 1, the modes such as welding, splicing, mechanical connection may be used in connection type, the present embodiment preferred weld
Mode, the assembly difficulty for reducing pilot valve simultaneously, connect more reliable.The height of limited block 42 is 2.3-2.7mm, the present embodiment
It is preferred that 2.5mm.
Since limit protrusion is constituted in the inner wall welding of conduit 1 or mechanical connection limited block 42, without being carried out to reed 8
Additional processing, thus it is simple in structure, the difficulty of processing of reed 8 is reduced, the assembly difficulty of pilot valve is also reduced.
