Abstract
The utility model belongs to technical field of hydraulic pressure, it is related to a kind of hydraulic valve end face seal structure, including valve body (1) and sealing ring (4), sealing ring (4) is in the seal groove of valve body (1), it is characterized in that: increase outer guard circle (2) between the seal groove outer ring and sealing ring (4) of valve body (1), guard circle (3) in increasing between the seal groove inner ring and sealing ring (4) of valve body (1), the utility model installs outer guard circle and interior guard circle in seal groove, two guard circles can play certain sealing function, additionally it is avoided that sealing ring is hurt by metal valve body, play the role of protecting sealing ring, to improve the reliability of end face seal structure.
Description
Technical field
The utility model belongs to technical field of hydraulic pressure, is related to a kind of hydraulic valve end face seal structure.
Background technique
It is generally existing in the leakage problem of the industrial circles such as Aeronautics and Astronautics, petroleum, chemical industry, hydraulic valve, it is Hydraulic Industry
Hard nut to crack develops in particular with the direction of Hydraulic Field towards high temperature, high pressure, high speed, and the chance of hydraulic valve leakage is got over
Come it is more, because seal failure generate leakage cause to occur accident danger it is increasing, caused by economic loss also can be increasingly
Greatly.Hydraulic valve leakage has safely very big threat to industrial production, therefore, it is necessary to provide a kind of hydraulic valve end of high reliablity
Surface seal structure.
Utility model content
The purpose of this utility model: a kind of hydraulic valve end face seal structure is provided.
The technical solution of the utility model includes: a kind of hydraulic valve end face seal structure, including valve body 1 and sealing ring 4, sealing ring
4 in the seal groove of valve body 1, it is characterized in that: increase outer guard circle 2, valve between the seal groove outer ring and sealing ring 4 of valve body 1
Guard circle 3 in increasing between the seal groove inner ring and sealing ring 4 of body 1.
The seal groove outer ring of the valve body 1 and outer guard circle 2 are interference fitted.
The seal groove inner ring of the valve body 1 and interior guard circle 3 are interference fitted.
The outer guard circle 2, interior guard circle 3 are fluoroplastics.
The utility model has the beneficial effects that installing outer guard circle and interior guard circle, two guard circles in seal groove can rise
It to certain sealing function, is additionally avoided that sealing ring is hurt by metal valve body, plays the role of protecting sealing ring, to improve
The reliability of end face seal structure.
Detailed description of the invention
Fig. 1 is the utility model structure bottom view.
Fig. 2 is the partial cutaway view of utility model structural front view.
In figure: 1 valve body, 2 outer guard circles, guard circle, 4 sealing rings in 3.
Specific embodiment
The utility model is described in more detail with reference to the accompanying drawing.
Fig. 1, Fig. 2 are please referred to, is the utility model structure bottom view and partial cutaway view.
A kind of hydraulic valve end face seal structure, including valve body 1 and sealing ring 4, sealing ring 4 are mounted in the seal groove of valve body 1,
Increase outer guard circle 2 between the seal groove outer ring and sealing ring 4 of valve body 1, increases between the seal groove inner ring and sealing ring 4 of valve body 1
Add interior guard circle 3.
The seal groove outer ring of the valve body 1 and outer guard circle 2 are interference fitted.
The seal groove inner ring of the valve body 1 and interior guard circle 3 are interference fitted.
The outer guard circle 2, interior guard circle 3 are fluoroplastics.
A kind of hydraulic valve end face seal structure, guard circle interference is installed in 1 valve seal slot in 2 outer guard circles and 3, and 4
Sealing ring is loaded between guard circle in 2 outer guard circles and 3, and guard circle can prevent 4 sealing rings by 1 valve body in 2 outer guard circles and 3
Damage, also functions to certain sealing function, to improve the reliability of end face seal structure sealing.
When work, valve body 1 is bolted in system, and high pressure liquid pressure oil is flowed out by oil-through-hole, guard circle in 3
It is the first line of defence for preventing hydraulic fluid leak, 4 sealing rings are to prevent the second defence line of hydraulic fluid leak, 2 outer guard circles
It is to prevent the three lines of defence of hydraulic fluid leak, guard circle can protect 4 sealing rings in 2 outer guard circles and 3, therefore, the liquid
Pressure valve end face seal structure can greatly improve the reliability of end face seal.
Claims (4)
