Abstract
The utility model relates to a valve seat provided with a mounting step. The valve seat is provided with a valve seat body. An inlet pipe body and an outlet pipe body are respectively arranged at two ends of the valve seat body. A working cavity in the valve seat body is respectively communicated with an inlet pipe cavity in the inlet pipe body and an outlet pipe cavity in the outlet pipe body. The central line of the inlet pipe body is overlapped with the central line of the outlet pipe body. A separating fence is arranged on the valve seat body and located at the bottom in the working cavity. The separating fence divides the working cavity into an inlet pipe working cavity and an outlet pipe working cavity. The mounting step is arranged at the upper end of the valve seat body. Through arrangement of the mounting step at the upper end of the valve seat body, the sealing performance between the valve seat and a valve deck can be improved when the valve seat is matched with the valve deck.
Description
Technical field
The utility model relates to a kind of valve seat with installation step.
Background technique
Seat design in the past is simple in structure, and installation step and so on is not set, and is that valve gap with matching is connected easily to occur the phenomenon revealed in the process.
The model utility content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of valve seat with installation step is provided, solve valve seat in the past causes valve seat and the valve bonnet seal poor performance that cooperates because lacking installation step defective.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of valve seat with installation step, has the valve seat body, described valve seat body two ends are respectively arranged with the inlet pipe body and go out body, the intrinsic active chamber of described valve seat communicates with inlet pipe chamber and the tube chamber that goes out that goes out in the body in the inlet pipe body respectively, the center line of described inlet pipe body coincides with the center line that goes out body, be provided with jube on the described valve seat body that is positioned at the active chamber inner bottom part, described jube is divided into active chamber the inlet pipe active chamber and goes out to manage active chamber, and described valve seat body upper end is provided with installation step.
Further, described jube and valve seat body are structure as a whole.
The beneficial effects of the utility model are: by the upper end at the valve seat body installation step is set, so that valve seat is can improve when valve gap matches sealability between the two.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 be valve seat partly cut open structural representation;
Wherein: 1, valve seat body, 2, the inlet pipe body, 3, go out body, 4, jube, 5, installation step.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of valve seat with installation step as shown in Figure 1, has valve seat body 1, valve seat body 1 two ends are respectively arranged with inlet pipe body 2 and go out body 3, active chamber in the valve seat body 1 respectively with inlet pipe body 2 in the inlet pipe chamber and the tube chamber that goes out that goes out in the body 3 communicate, the center line of inlet pipe body 2 coincides with the center line that goes out body 3, be positioned on the valve seat body 1 of active chamber inner bottom part and be provided with jube 4, jube 4 is divided into active chamber the inlet pipe active chamber and goes out to manage active chamber, valve seat body 1 upper end is provided with installation step 5, and jube 4 is structure as a whole with valve seat body 1.
By the upper end at valve seat body 1 installation step 5 is set, so that valve seat is can improve when valve gap matches sealability between the two.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this model utility technological thought, carry out various change and modification fully.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
