It is solid unitary structure after processing.The stainless steel main valve for the solid unitary structure being processed into using stainless steel abnormity material
Not only processing technology is complicated for seat, and manufacturing procedure is more and needs multiple annealing and pickling, and solder yield is low, and not only cost is high for technique
Also not environmentally, such as Publication No. " CN102200190B ", the Chinese invention of entitled " a kind of four-way reversing valve " are special for pole
A kind of four-way reversing valve is disclosed in profit, the four-way reversing valve is fixed multiple including valve body, valve seat, together with valve body, valve seat
Adapter, valve seat includes a sealing for being used to be engaged sealing with the sliding block of four-way reversing valve and one is used for and the adapter
The connecting portion of mating connection, the outer wall of the connecting portion of the valve seat is arc line shaped, and the valve seat closes for metal, the metal of low heat conduction
What gold or nonmetallic materials were molded by injecting machine-shaping or die-casting process.In this programme, due to the structure of valve seat in itself
It is complex, therefore the molding structure of valve seat is complicated, shaping cost is higher.And switching valve split valve seat construction, split valve seat it
Between typically use spot welding, be not continuously to weld, valve seat and take over last integral solder when, it may occur that valve seat and adapter between
Insufficient solder connection, or solder cause solder between filling the end face that split valve seat connects to fill from the gap outflow between spot welding
Deficiency, gap is formed, causes to leak.
The content of the invention
The technical problems to be solved by the invention be to provide a kind of switching valve base and sealing plate it is separately machined and at it
Continuously weld firm switching valve in corresponding surrounding.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：A kind of switching valve, including valve body, valve seat
And sliding block, the valve seat include the D-shaped base being fixedly installed in the valve body and the sealing being fixedly installed on the base
Plate, the sealing plate are tabular, and the sliding block coordinates with sealing plate sealing, and is slidably arranged in the sealing plate upper table
Face, the upper plane of the D-shaped base and sealing plate lower surface are in length direction joint formed with continuous weld.
The upper plane of the D-shaped base and sealing plate lower surface are in width joint formed with continuous weld.
The D-shaped base width is equal to sealing plate width.
The D-shaped base width is less than sealing plate width.
Laser Welding or argon arc welding are used between the D-shaped base and sealing plate.
The D-shaped base is iron and steel sheet and plate punch forming, and the sealing plate is iron and steel sheet and plate punch forming；Or the D-shaped
Base is iron and steel sheet and plate punch forming, and the sealing plate is molded for steel powder metallurgical processing；Or the D-shaped base is steel powder
Last metallurgical processing shaping, the sealing plate is iron and steel sheet and plate punch forming.
The beneficial effects of the invention are as follows：The base and sealing plate of switching valve are independently arranged, and save material, easy processing, and even
Continuous firm welding.

Embodiment
The present invention is described in further detail with reference to the accompanying drawings and detailed description：
As shown in Figures 1 to 4, a kind of switching valve, including valve body 1, valve seat 2 and sliding block 3, the valve seat 2 include fixation and set
The D-shaped base 4 in the valve body 1 and the sealing plate 5 being fixedly installed on the D types base 4 are put, the sealing plate 5 is flat
Tabular, the sliding block 3 coordinates with the upper surface of sealing plate 5 sealing, and is slidably arranged on the sealing plate 5, D types base 4
On the hole formed with connection connecting tube 6, connecting tube 6 welds through this hole and D types base 4.The upper plane and sealing plate 5 of D-shaped base 4
Lower surface is docked, and is that D types base 4 and sealing plate 5 are welded in two side abutment joints 7 of length direction using continuous, D-shaped base 4
Welded with both sides abutment joint (not shown) of the sealing plate 5 in width using continuous, D types base 4 and sealing plate 5 are distinguished
Independent shaping manufacture, technique is simple, and materials are few, binding site using continuous welding can ensure its it is firm simultaneously as
Weld seam does not influence being welded to connect for connecting tube 6 on D types base 4 away from connection pore.It is wide that the width of D-shaped base 4 is equal to sealing plate 5
