Abstract
The utility model discloses a one-way valve, comprising a valve body, a valve seat, a steel ball, a spring and a retaining ring, wherein, the valve body is fixed inside with the valve seat and the retaining ring; the valve seat is provided inside with the slidable steel ball; the spring is arranged between the steel ball and the retaining ring. The utility model avoids the rolling noise of the valve plug when working and the impact noise when the valve plug reverses by making use of the constraint action of the spring on the valve plug and the damping action of a freezing medium on the valve plug. The invention adopts a spherical sealing mode with simple structure and good sealing effect. The one-way valve is normally in a closing state, avoids the damage to the valve seat and the retaining ring due to arbitrary arrangement of the steel ball. The utility model provides a one-way valve which has good sealing effect, low reversing noise and long service life.
Description
Technical field:
The present invention relates to a kind of one-way valve, refer in particular to a kind of one-way valve that is used for the heat pump refrigerating system.
Background technique:
One-way valve is as a kind of element of restricted flow direction of flow, capillary section streaming system normal and heat pump is used, prevent to heat the reverse flow of refrigeration agent when changing, adjust refrigeration, heat refrigerant flow required in the circulation, balance refrigeration, the capillary pressuring difference when heating with refrigeration cycle.When on the outlet pipe that is installed in compressor, then can prevent to flow backwards at high temperature return-air out of service when compressor.
Metal ball-valve and plastics cone valve all can be used for the heat pump refrigerating system.The existing one-way valve that is used for the heat pump refrigerating system, mainly contain two kinds of structures of cone valve and ball valve, China generally adopts cone valve, utilize the taper valve core and the brass valve seat of polytetrafluoroethylmaterial material processing to be sealed and matched, utilize contacting of plastics and metal, all adopted cone valve structure as CN2395102, CN2315387 number open text to reduce impact force.But cone valve is because of the machining error and the guiding deviation of the conical surface, and sealing is relatively poor.
Much more external adopt the more convenient ball-valve structure of processing, but the Metal Ball core is placed on freely in the valve seat, all adopted this structure as US04100935, US05799689, US05785083, US04071045.The impact force of bump valve nozzle was big when metal spool moved back and forth, and spool freely rolls in valve body during system works, and noise is bigger, and long-term use easily causes the sealing surface distortion impaired, leaked in causing to increase.
For avoiding above defective, the spool of CN2898729 number open text is formed by the cone spool transformation of the way, adopts the sealing of sphere chamfering and cone match, but has the directly problem of bump of spool and valve seat equally.CN2607495 number open text has adopted needle-valve in the refrigeration system of refrigerator, but the complex structure of this valve, processing difficulties.
Summary of the invention:
Be the deficiency of avoiding existing ball valve and the defective of cone valve and needle-valve, the invention provides that a kind of good seal performance, commutation noise are low, the non-return valve of long service life.
A kind of one-way valve that is used for the heat pump refrigerating system, comprise valve body, valve seat, steel ball, spring and Non-return ring, the valve body internal fixation has valve seat and Non-return ring, valve seat is provided with valve opening and slideway, slidably steel ball is housed in the described slideway, be provided with spring between steel ball and the Non-return ring, also be provided with through hole on the Non-return ring.
Valve opening one end of described valve seat is entrenched togather by the groove groove corresponding with valve body, and slideway one end is provided with steel ball slided and play the guiding role and the taper hole of guide functions.
Described Non-return ring is entrenched togather by groove and valve body corresponding groove, and the end that Non-return ring is relative with valve seat is provided with the annular projection that spring is played location and installation effect.
The present invention adopts ball face sealing, and is simple in structure, good sealing effect.One-way valve is in closed state usually, and the bump of having avoided steel ball free to lay for valve seat and Non-return ring damages.During the one-way valve conducting, because the buffer function of elastic force, steel ball can not produce bump to Non-return ring, and has avoided the generation of operational noise.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of heat pump refrigerating system one-way valve, comprise valve body 1, valve seat 2, steel ball 3, spring 4 and Non-return ring 5, valve body 1 internal fixation has valve seat 2 and Non-return ring 4, valve seat 2 is provided with valve opening 201 and slideway 202, and slidably steel ball 3 is housed in the slideway 202, and the right-hand member of slideway 202 is taper holes 203, be provided with spring 4 between steel ball 3 and the Non-return ring 5, also be provided with through hole 501,502 on the Non-return ring 5.
When one-way valve is used for the capillary section streaming system, in refrigeration cycle, refrigeration agent enters from the left end of valve body 1, under system pressure, steel ball 3 slides into taper hole 203 positions to the right, the aperture increases, and taper hole 3 plays the guide functions to refrigeration agent, and refrigeration agent enters valve body 1 right-hand member, right-hand member pressure raises, the system pressure difference that steel ball 3 is suffered and the elastic force of spring 4 keep balance, and steel ball 3 can not bump with Non-return ring 4, and steel ball can not take place freely to roll under spring constraint.When refrigeration cycle quits work, valve body left end pressure reduces, steel ball 3 return under the leading role of taper hole 203 enters slideway 4, because the damping function of refrigeration agent, return speed is slack-off, thereby reduced the impact of the port of 3 pairs of valve openings 201 of steel ball, reduced noise and prolonged working life of one-way valve.In heating circulation, refrigeration agent enters from the right-hand member of valve body 1, and owing to steel ball 3 port of close valve orifice 201, refrigeration agent can not pass through, and steel ball remains static simultaneously, and no free travel can not produce valve seat and impact.
