Description

A kind of discharge chamber refrigeration compressor cylinder body with boss

Technical field

This utility model relates to a kind of refrigeration compressor cylinder body, especially relates to a kind of discharge chamber refrigeration compressor cylinder body with boss.

Background technology

The exhaust noise silencing structure of existing hermetically sealed compressor includes cylinder body body, capping, cylinder body body is provided with discharge chamber, cylinder body body bottom discharge chamber is threaded hole, described capping is to be flexibly connected with the screwed hole composition screw thread on cylinder body body by connecting bolt and seal up discharge chamber, so that defining an exhaust noise silencing chamber closed between capping and cylinder body body.But, owing to being the screwed hole arranged on direct cylinder body body bottom discharge chamber, therefore, the thickness making cylinder body body correspondingly increases, height of cylinder cannot being effectively reduced, thus causing that the total height of compressor also cannot reduce, being unfavorable for that the miniaturization of compressor tends to.

Utility model content

The technical problems to be solved in the utility model is: for prior art Problems existing, it is provided that a kind of discharge chamber refrigeration compressor cylinder body with boss, even when not changing discharge chamber capacity, it is also possible to be effectively reduced the total height of cylinder body.

The technical problems to be solved in the utility model realizes by the following technical solutions: a kind of discharge chamber refrigeration compressor cylinder body with boss, including cylinder body body, cylinder body body offers discharge chamber, arrange in described discharge chamber and fix, with cylinder body body, the boss being connected, boss is offered screwed hole.

Preferably, described boss is round table-like.

Preferably, fixing between the relatively large end of external diameter in described boss and cylinder body body it is connected.

Preferably, it is that integrated molding is connected between described boss with cylinder body body.

Preferably, described boss is the foundry goods solid formed by casting.

Preferably, described boss is to adopt gray cast iron material casting.

Preferably, also including capping and connecting bolt, offer through hole in capping, described connecting bolt forms screw thread with the screwed hole on boss after running through capping and is flexibly connected, and described capping covers and seals discharge chamber.

Preferably, described discharge chamber arranges two, is respectively provided with and fixes, with cylinder body body, the boss being connected in each discharge chamber, all offers screwed hole on boss.

Preferably, two described discharge chambers are to be arranged symmetrically with the central axis of cylinder body body for axis of symmetry.

Preferably, described cylinder body body is to adopt gray cast iron material casting.

Compared with prior art, the beneficial effects of the utility model are: fix, with cylinder body body, the boss being connected owing to arranging in discharge chamber, boss is offered screwed hole, therefore, so that connecting bolt is flexibly connected with the screwed hole composition screw thread on boss after running through capping, an exhaust noise silencing chamber closed can be formed between cylinder body body so that covering.After adopting this structure, though when do not change exhaust cavity capacity, without increase cylinder body body thickness, it is also possible to realize the reduction of compressor cylinder height, thus significantly reducing the overall height of compressor.

Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with the drawings and specific embodiments, this utility model is described in detail.Should be appreciated that specific embodiment described herein is only in order to explain this utility model, be not used to limit this utility model.

The refrigeration compressor cylinder body with boss of a kind of discharge chamber as shown in Figure 1, including cylinder body body 1, capping 4 and connecting bolt 5, described cylinder body body 1 is as shown in Figure 2 and Figure 3, cylinder body body 1 is offered discharge chamber 3, the boss 2 that be connected fixing with cylinder body body 1 is set in discharge chamber 3, boss 2 is offered screwed hole 7.Described capping 4 as shown in Figure 4, offers through hole in the centre of capping 4.Described connecting bolt 5 forms screw thread with the screwed hole 7 on boss 2 after running through capping 4 and is flexibly connected, and described capping 4 covers and seal discharge chamber 3, therefore, defines an exhaust noise silencing chamber closed between capping 4 and cylinder body body 1.After adopting this structural design, when the refrigerant gas of compressor is through the exhaust noise silencing chamber of this closing, it is possible to reduce amplitude and the frequency of the pneumatic noise ripple of the high pressure gas refrigerant gas of compressor, advantageously reduce the exhaust airstream noise of compressor；Additionally, owing to the connection between capping 4 and cylinder body body 1 is to form screw thread with the screwed hole 7 on boss 2 by connecting bolt 5 to be flexibly connected and realize, and the shared space of boss 2 itself is only small, therefore, even if when do not change exhaust cavity capacity, without increase cylinder body body thickness, the reduction of compressor cylinder height can also be easily carried out, thus significantly reducing the overall height of compressor.

In order to improve the bonding strength between boss 2 and cylinder body body 1, ensure the connection reliability between capping 4 and cylinder body body 1, described boss 2 can be designed to round table-like, and fixing between the relatively large end of external diameter and the cylinder body body 1 in boss 2 is connected, as shown in Figure 1, Figure 3.Described cylinder body body 1 can be adopt gray cast iron material casting, and its integral workblank is by mould founding casting.Described boss 2 can also be the foundry goods solid adopting gray cast iron material casting, then on this foundry goods solid, process the screwed hole 7 matched with connecting bolt 5, make between boss 2 and cylinder body body 1, to be integrally forming chemical conversion type attachment structure by forging type, it is easy to the boss 2 reasonable Arrangement in discharge chamber 3, it is not only simple in structure, implementation cost is low, and is conducive to strengthening the bonding strength between boss 2 and cylinder body body 1.

It should be noted that, as shown in Figure 1, Figure 2, Figure 3 shows, described discharge chamber 3 can arrange two, and described two discharge chambers 3 are arranged symmetrically in the opposite sides of cylinder head 6 with the central axis of cylinder body body 1 for axis of symmetry, the boss 2 that be connected fixing with cylinder body body 1 it is respectively provided with in each discharge chamber 3, all offering screwed hole 7 on boss 2, each discharge chamber 3 is respectively adopted connecting bolt 5 and coordinates seal with capping 4, thus defining the exhaust noise silencing chamber of two independent closings；Described capping 4 can also adopt cross sectional shape v-shaped structure capping as shown in Figure 4, to increase the capacity of discharge chamber 3.Adopt this structural design, not only contribute to the balance of compressor movement, and be conducive to reducing further the exhaust airstream noise of compressor.

The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; it should be pointed out that, all any amendment, equivalent replacement and improvement etc. made within spirit of the present utility model and principle, should be included within protection domain of the present utility model.
