It states in assembly cavity.Specifically, first group of bumps 11 and second group of bumps 12 are recessed inwardly by the tube wall of the valve body 1
It is formed, the spool 2 is fixed in the valve body 1 by this simple and reliable for structurely.
The sealing ring 3 is installed on the sealing realized between the valve body 1 and the spool 2 between the two, described close
Seal 3 is made of rubber material.The installation between valve body 1 and spool 2 is realized using sealing ring 3, eliminates the production of throttle valve 100
The step of realizing sealing is rolled or squeezed in the process, production difficulty is reduced, avoids the destruction to throttling passage 21, improve
Production efficiency and production yield, while reusing welding manner and carrying out the components such as the throttle valve 100 and other pipelines
When connection, uneven heating between valve body 1 and the spool 2 is avoided so that the situation that sealing structure is destroyed, reduces installation
Difficulty installs more convenient convenience, it is ensured that be equipped with the throttling precision of the refrigeration system of the throttle valve 100.
The valve body 1, which has, to be connected to and along the import of the axially opposing setting of the valve body 1, outlet, institute with the assembly cavity
Spool 2 is stated with first end 201 and second end 202 along its axially opposing setting, the sealing ring 3 is apart from the first end
201 first distance is less than second distance of the sealing ring 3 apart from the second end 202, and the spool 2 is assemblied in the dress
After intracavitary, the first end 201, the second end 202 are respectively close to the import, the outlet, so that less fluid
Into between the first end 201 and the sealing ring 3, fluid is made full use of, the loss of fluid is reduced.
Preferably, the spool 2 has from its outer surface and is recessed radially inward the annular groove 22 of formation, the sealing
Circle 3 is flush-mounted between the annular groove 22 and the inner wall of the assembly cavity.After the sealing ring 3 is installed, the sealing
The inner wall of circle 3 is close to the bottom wall of the annular groove 22, and the outer wall of the sealing ring 3 is close to the inner wall of the assembly cavity, with reality
Sealing between existing spool 2 and the valve body 1.Preferably, the sealing ring 3 is in a free state, the sealing ring 3
Internal diameter is slightly less than the diameter of the bottom wall of the annular groove 22, and the outer diameter of the sealing ring 3 is slightly larger than the inner wall of the assembly cavity
Diameter.
The throttle valve 100 further includes being installed in the assembly cavity and being located at second group of bumps 12 and the outlet
Between filter screen (not shown), the filter screen and the valve body 1 are fixed, and the filter screen is stainless steel mesh grid,
For filtering the impurity in fluid.
The invention also discloses a kind of refrigeration systems, including above-mentioned throttle valve 100, to pass through adjusting spool 2
Quantity reaches adjusting amount of restriction, while having reliable and stable leakproofness.The refrigeration system is for temperature-adjusting devices such as air-conditionings.
In refrigeration systems, the throttle valve 100 can cooperate with check valve, realize one-way throttle function.
In conclusion the throttle valve 100 of the utility model can assemble at least one spool 2 by the assembly cavity, from
And can achieve the purpose that adjust amount of restriction by the quantity of adjusting spool 2, without being designed not to adapt to different amount of restriction
