Abstract
The utility model discloses an inlet valve upper structure and relates to a gas engine component. The inlet valve upper structure comprises an inlet valve body and a rotary spring upper seat. The rotary spring upper seat is sleeved on the upper portion of the inlet valve body. Two valve lock clamps are arranged at the joint of the rotary spring upper seat with the inlet valve body. The inlet valve upper structure is simple in structure and convenient to mount. The rotary spring upper seat enables an inlet valve to move up and down in a gas valve guide tube and also axially rotate around a center shaft of the inlet valve, so that loss can be lowered effectively and the service life of the inlet valve is prolonged.
Description
Technical field
The utility model relates to a kind of gas engine assembly, is specifically related to a kind of intake valve superstructure.
Background technique
Present intake valve structurally generally adopts direct rod shape, and on intake valve top the torsional spring seat of honour is not installed, cause intake valve only in combustion gas door conduit, to move up and down, and can't axial rotation, when gas engine turns round, so that the loss of intake valve bottom is large, thereby greatly shortened the working life of intake valve.
The model utility content
The purpose of model utility: for addressing the above problem, the utility model provides a kind of intake valve superstructure.
Technological scheme: a kind of intake valve superstructure, comprise the intake valve body, the top of described intake valve body is socketed with the torsional spring seat of honour, and the junction of the described torsional spring seat of honour and intake valve body is provided with valve collet.
As preferably, described valve collet number is 2.
Beneficial effect: a kind of intake valve superstructure described in the utility model, simple in structure, easy for installation, because the torsional spring seat of honour has been installed, so that when intake valve moves up and down in combustion gas door conduit, can also make axial rotation around the central shaft of intake valve, can effectively reduce loss like this, increase the working life of intake valve.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is sectional view of the present utility model.
Embodiment
A kind of intake valve superstructure as shown in Figure 1, 2 comprises intake valve body 1, and the top of intake valve body 1 is socketed with the torsional spring seat of honour 2, and the torsional spring seat of honour 2 is provided with valve collet 3 with the junction of intake valve body 1, and valve collet 3 numbers are 2.
Because the torsional spring seat of honour 2 has been installed, when gas engine turns round, so that intake valve body 1 not only can move up and down in combustion gas door conduit, all right axial rotation, the High Temperature High Pressure that makes the running of gas engine cylinder internal cause and produce becomes more even to the effect of intake valve body 1 bottom, has reduced the loss of intake valve body 1.
Claims (2)
1. intake valve superstructure, comprise intake valve body (1), it is characterized in that: the top of described intake valve body (1) is socketed with the torsional spring seat of honour (2), and the described torsional spring seat of honour (2) is provided with valve collet (3) with the junction of intake valve body (1).
2. a kind of intake valve superstructure according to claim 1, it is characterized in that: described valve collet (3) number is 2.
