Description

A kind of opened by pressure breather valve
Technical field
The utility model relates to reducer technology fields, and in particular to a kind of opened by pressure breather valve of speed reducer.
Background technique
For the needs of pressure release on the cavity of speed reducer, it usually needs be equipped with opened by pressure on the cavity of speed reducer Breather valve guarantees the safety of cavity so that in internal pressure increase, pressure is released for cavity.
However, the structure of current breather valve is relatively complicated, it is at high cost, and be inconvenient to install, therefore, it is necessary to carry out It improves.
Utility model content
The purpose of this utility model and is provided on a kind of speed reducer cavity for technological deficiency existing in the prior art Opened by pressure breather valve.
It is for technical solution used by realization the purpose of this utility model:
A kind of opened by pressure breather valve, the spiral shell being threadedly coupled including the internal screw thread pressure relief opening on the cavity with speed reducer Line connector and with the valve deck for being threadedly coupled body threaded connection, the valve deck be threadedly coupled after body is connect internal one A cavity being axially arranged, is equipped with moveable core assembly in the cavity, the core assembly include valve rod and with institute The spool of the cone structure of valve rod connection is stated, positioning disk is set on the valve rod, the side bonding of the positioning disk is flexible Sealing ring, the inside for being threadedly coupled body form the relief hole with spool cooperation, and the internal diameter of the relief hole is less than institute The outer diameter of positioning disk is stated, the internal diameter of the elastic seal ring is less than the internal diameter of the relief hole.
The valve deck have male threaded joint, the threadeds connection body have with the male threaded joint cooperate in Threaded joints form multiple air channels axially arranged on the surface of the male threaded joint.
Venthole is formed on the end face of one end that the threaded connection body is connect with the valve deck.
The utility model opened by pressure breather valve, being able to achieve speed reducer cavity internal pressure increase is Shi Kaiqi, and pressure is let out Fall, keeps the balance and stability of speed reducer cavity internal pressure, and structure is simple, conveniently installs and uses.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the semi-section of opened by pressure breather valve;
Fig. 2 is the semi-section structural schematic diagram of valve deck;
Fig. 3 is the structural schematic diagram of core assembly;
Fig. 4 is the left view schematic diagram of opened by pressure breather valve;
Fig. 5 is the schematic front view of the male threaded joint of core cap.
Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.
Referring to shown in Fig. 1-5, a kind of opened by pressure breather valve, including the internal screw thread pressure release on the cavity with speed reducer Mouthful be threadedly coupled threadeds connection body 1 and with it is described be threadedly coupled body be threadedly coupled valve deck 9, the valve deck be threadedly coupled Moveable core assembly, the spool group are installed in an internal cavity being axially arranged, the cavity after body connection Part includes the spool 5 of valve rod 7 and the cone structure connecting with the valve rod, and positioning disk 6, the guiding are set on the valve rod The side of disk is bonded with elastic seal ring 8, and the inside for being threadedly coupled body forms the relief hole 4 with spool cooperation, institute The internal diameter for stating relief hole is less than the outer diameter of the positioning disk, and the internal diameter of the elastic seal ring is less than the internal diameter of the relief hole.
Wherein, the cavity is round chamber, is formed by the cavity 10 of the inside of valve deck with intracorporal vestibule is threadedly coupled, Spring 11 is set on the valve rod, one end of the spring 11 is abutted with the cavity inner face of valve deck, and the other end, which is pressed on, leads To on the medial surface of disk.
Wherein, the threaded joints have the threaded portion 2 being connected with pressure relief opening, and connection is facilitated to use.In screw thread The inside of interconnecting piece forms the pressure release cavity 3 of flared connecting with its internal relief hole 4.
Wherein, the side of the valve deck forms the interconnecting piece 17 of minor diameter, has male threaded joint on the interconnecting piece 171, the body 1 that is threadedly coupled has the female threaded joint cooperated with the male threaded joint, the male threaded joint Multiple air channels 172 axially arranged are formed on 171 surface.
Further, radial venthole is formed on the end face of one end that the threaded connection body is connect with the valve deck (or slot) 12.In this way when in speed reducer cavity being positive pressure, pressure pushes spool to left side, and relief hole 4 is opened, gas is made It is released through pressure release cavity 3, relief hole 4, then passes through air channel 172, the undergauge in the left side of the interconnecting piece 17 of the minor diameter of valve deck Circular passage 15 and annular gap 13 and radial venthole (or slot) 12 are formed between area's inner wall corresponding with threaded joints Afterwards, the gap reserved between the inner wall and threaded joints after being discharged between the inner wall of valve deck and threaded joints, then through valve deck Discharge, so that extra air be discharged, protect oil sealing when realizing in speed reducer cavity as positive pressure.
Wherein, the valve deck medial surface is formed with annular groove 16, valve deck be threadedly coupled body be threadedly coupled it is peppery, it is described Be threadedly coupled body corresponding end formed auxiliary section 14 be inserted into the annular groove 16, and between the auxiliary section 14 and inside and outside wall with Interval is formed between two inner sidewalls of annular groove 16, is not contacted, the bottom end face contact of top and annular groove is able to achieve pressure release in this way Realization.
The utility model opened by pressure breather valve, being able to achieve speed reducer cavity internal pressure increase is Shi Kaiqi, and pressure is let out Fall, keeps the balance and stability of speed reducer cavity internal pressure, and structure is simple, conveniently installs and uses.
The above is only the preferred embodiment of the utility model, it is noted that for the general of the art For logical technical staff, without departing from the principle of this utility model, several improvements and modifications can also be made, these change It also should be regarded as the protection scope of the utility model into retouching.
