Description
Technical field
The utility model belongs to valve field, relates to sealing configuration, especially a kind of H type valve seat shape metallic leak-proof structure.
Background technique
Valve is in fluid system, be used for controlling the direction of fluid, pressure, flow device be the medium in pipe arrangement and equipment (liquid, gas, powder) is flowed or stops and the device of its flow can be controlled.For the valve be operated under exceedingly odious single or multiple integrated environments, the sealing configuration of common rubber valve seat is very easy to damage, and maintenance work is loaded down with trivial details, thus working life of valve sealing structure and reliability particularly important.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of structure simple, reasonable in design, safe and reliable, lower-cost H type valve seat shape metallic leak-proof structure.
The utility model solves its technical problem and takes following technological scheme to realize:
A kind of H type valve seat shape metallic leak-proof structure, comprise valve body, valve seat and cutting device, axial passage is shaped with in valve body, drive installation of leading in this valve channel has cutting device, all valve seat is coaxially installed with between the valve seal surface of contact of this cutting device and passage both sides, it is characterized in that: in the middle part of the valve seat of the axial surface of contact with valve body, be coaxially shaped with an annular mounting groove, coordinate in this annular mounting groove and a H type metal seat valve seal ring is installed, the H-shaped structure in the cross section of this H type metal seat valve seal ring, the axial end of tactile valve body and valve seat is pressed on two lateral lip limits of this H type metal seat valve seal ring respectively.
And described cutting device is valve plate or valve ball.
Advantage of the present utility model and good effect are:
The utility model is applicable to the valve such as plate valve, ball valve, is a kind of pure metal hard sealing structure, and rely on liquid internal pressure to play better sealing effect, sealing reliability is strong.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model is applied to plate valve;
Fig. 2 is the structural representation that the utility model is applied to ball valve;
Fig. 3 is the utility model initial sealing structure;
Fig. 4 is Fig. 3 pressure self-sealing structural representation.
Mark representative in accompanying drawing: 1 valve body; 2 valve seats; 3H type metal seat valve seal ring; 4 cutting devices.
Embodiment
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of H type valve seat shape metallic leak-proof structure, be applicable to the valve such as plate valve, ball valve, comprise valve body 1, valve seat 2 and cutting device 4, axial passage is shaped with in valve body, drive installation of leading in this valve channel has cutting device, is all coaxially installed with valve seat between the valve seal surface of contact of this cutting device and passage both sides.
In the present embodiment, cutting device is valve plate or valve ball.
Innovative point of the present utility model is:
An annular mounting groove is coaxially shaped with in the middle part of the valve seat of the axial surface of contact with valve body, coordinate in this annular mounting groove and a H type metal seat valve seal ring 3 is installed, the H-shaped structure in the cross section of this H type metal seat valve seal ring, the axial end of tactile valve body and valve seat is pressed on two lateral lip limits of this H type metal seat valve seal ring respectively.
Working principle of the present utility model is:
Liquid flows through valve body, valve seat, liquid extrudes the gap entered between valve body and valve seat, pressure acts on H type metal seat valve seal ring and entered certain precompressed, as shown in Figure 3, make valve body, valve seat and, H type metal seat valve seal ring has certain sealing force thus reaches the object of initial sealing.
Along with the rising of pressure, H type metal seat valve seal ring generation resiliently deformable, as shown in Figure 4, the lip limit of H type metal seat valve seal ring acts on, the power of valve body, valve seat increases along with the rising of pressure, and its sealability is also more reliable along with the rising of pressure.
Claims (2)
1. a H type valve seat shape metallic leak-proof structure, comprise valve body, valve seat and cutting device, axial passage is shaped with in valve body, drive installation of leading in this valve channel has cutting device, all valve seat is coaxially installed with between the valve seal surface of contact of this cutting device and passage both sides, it is characterized in that: in the middle part of the valve seat of the axial surface of contact with valve body, be coaxially shaped with an annular mounting groove, coordinate in this annular mounting groove and a H type metal seat valve seal ring is installed, the H-shaped structure in the cross section of this H type metal seat valve seal ring, the axial end of tactile valve body and valve seat is pressed on two lateral lip limits of this H type metal seat valve seal ring respectively.
2. H type valve seat shape metallic leak-proof structure according to claim 1, is characterized in that: described cutting device is valve plate or valve ball.
