Description

Improved silencer for electromagnetic valve

Technical Field

The utility model relates to an improvement type silencer for solenoid valve.

Background

An electromagnetic valve in a pneumatic element can generate exhaust in the working process of a cylinder, and a standard part of a silencing terminal on the market is easy to damage in the industry; meanwhile, in the air supply process of the air compressor, a small amount of moisture in the air is reserved in the electromagnetic valve, and the standard part of the silencing terminal cannot discharge the moisture. In this case, the life of the solenoid valve and the cylinder is reduced, and the work efficiency is lowered.

Therefore, the chinese utility model with the prior publication number CN206708535U discloses "a silencer special for electromagnetic valve", which includes: the top of the connector is provided with a plurality of air inlets; the inner silencing tube is fixed at the bottom of the joint, and a plurality of inner silencing holes which are distributed in parallel at intervals and at equal intervals are formed in the side wall of the inner silencing tube; and the outer silencing barrel is fixed at the bottom of the joint and completely wraps the inner silencing barrel, the side wall of the outer silencing barrel is provided with an outer silencing hole corresponding to the inner silencing hole, and the inner silencing hole is connected with the corresponding outer silencing hole through a conical drainage silencing pipe which gradually expands from inside to outside.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to prior art's current situation, provide an improvement type silencer for solenoid valve, can absorb the moisture in the gas when falling the sound noise reduction, simultaneously, prevent that outside dust from getting into in the solenoid valve.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: an improvement type silencer for solenoid valve which characterized in that: the shell is internally provided with a cavity, the lower end of the shell is provided with connecting threads, the shell is provided with a through hole, and the cavity is filled with an absorbing material.

As an improvement, the top of the shell is detachably provided with a shell cover.

And in the improvement, the through hole is arranged on the side wall of the shell and/or on the shell cover.

In a further improvement, the array of through holes is disposed on an outer sidewall of the housing.

And a middle through hole is formed in the middle of the shell cover, and a sintering block formed by sintering copper particles is fixedly arranged in the middle through hole.

And the sintered block is flat-head-shaped or sharp-head-shaped.

And the top of the shell cover is provided with a rotating groove.

And the outer side wall of the shell cover is provided with a rotating sheet.

And the through hole is a tapered hole gradually enlarged from inside to outside.

And the shell is sleeved outside the shell, a connecting column is formed on the outer wall of the shell and arranged between the outer wall of the shell and the shell, and the conical hole is formed in the connecting column.

Compared with the prior art, the utility model has the advantages of: the utility model provides a silencer is installed on the solenoid valve, and the absorbing material of casing not only can the noise absorbing, simultaneously, can also absorb moisture in the gas, in addition, owing to receive absorbing material's separation effect, dust in the external environment is also difficult for entering into in the solenoid valve, only need regularly change absorbing material or silencer can.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

Example 1

As shown in fig. 1, the improved muffler for a solenoid valve according to the present embodiment includes a housing 1, a housing cover 2, and an absorbing material.

Wherein, be formed with the cavity in the casing 1, be formed with connecting thread 12 at the lower extreme of casing 1, seted up through-hole 11 on casing 1, the cavity intussuseption is filled with absorbent material, and preferably, absorbent material is one or several of fibre, cotton fibre, sponge and constitutes.

Further, a cover 2 is detachably provided on the top of the housing 1 in order to allow replacement of the absorbing material. Meanwhile, in order to facilitate the opening of the shell cover 2, a rotating groove 21 is formed in the top of the shell cover 2; alternatively, the rotating piece 22 is formed on the outer side wall of the cover 2.

In addition, in the embodiment of the present invention, the through hole 11 is opened on the side wall of the housing 1 and/or covered on the housing; alternatively, the array of through holes 11 is arranged on the outer side wall of the housing 1.

Furthermore, the through hole 11 is a tapered hole which gradually increases from inside to outside, the through hole 11 is designed to be of a tapered hole structure, after water vapor enters the chamber, in the process of passing through the tapered hole, the pressure is gradually released, and the water vapor of large particles is gradually atomized, so that a better drainage effect is achieved.

And simultaneously, in the embodiment of the utility model, for set up the bell mouth structure better, be equipped with the clamshell at the outside cover of casing 1, be formed with the spliced pole on casing 1 outer wall, the spliced pole sets up between casing 1 outer wall and clamshell, and the bell mouth sets up on the spliced pole.

During the use, the utility model provides a silencer is installed on the solenoid valve, and the absorbing material of casing 1 not only can the noise absorbing, simultaneously, can also absorb moisture in the gas, in addition, owing to receive absorbing material's separation effect, dust in the external environment is also difficult for entering into the solenoid valve in, only need regularly change absorbing material or silencer can.

Example 2

As shown in fig. 2 and 3, the technical difference between the present embodiment 2 and the embodiment 1 is that a middle through hole is formed in the middle of the case cover 2, and a sintered block 3 sintered from copper particles is fixedly disposed in the middle through hole. Preferably, the sintered cake 3 is flat-headed or pointed. The noise reduction level is improved by adding the top sinter cake 3 structure on the basis of the absorbing material.
