Abstract
The utility model relates to a clamp valve pressure test blind plate structure comprising a test valve, a blind plate main body, a O-shaped ring and a blind plate O-shaped ring. The pressure test port of the test valve is coaxially provided with the blind plate main body in a press fitting manner through a pressure test machine. The middle portion of the blind plate main body is coaxially provided with a pressure test channel. The O-shaped ring is coaxially embedded and installed into the outer wall of the blind plate main body on the outer side of the pressure test channel. The blind plate O-shaped ring is coaxially installed on the middle portion of the outer side of the blind plate main body. A sealing gasket made from an nylon material is coaxially embedded and installed into the middle portion of the inner side of the blind plate main body at a position which is in contact with the test valve. The sealing gasket is provided with a tapered raised head. The test port of the test valve is provided with a tapered groove matched with the sealing gasket. According to the utility model, advantages of scientific design, simple structure, working reliability and simple machining can be realized, and the nylon material is adopted, so the advantage of good sealing function can be realized, so that the service life of the seal ring can be greatly improved, and the clamp valve pressure test blind plate structure can be widely used in clamp valve pressure tests.
Description
Technical field
The utility model belongs to valve class, especially a kind of PRESSURE TESTING BLIND FLANGE structure of clamping hoop type valve.
Background technology
Clamping hoop type value pressure test blind plate normally adopts " taper " structure, reaches sealing effectiveness by pinch off channel, higher for channel edge requirement on machining accuracy, and this structure pilot press pressure easily causes passage damage, and installs inconvenient.By shell ring, back-up ring, double-screw bolt, the nut PRESSURE TESTING BLIND FLANGE structure that is formed by connecting for blind plate, operate more loaded down with trivial detailsly, at the bottom of work efficiency, and security is lower.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of PRESSURE TESTING BLIND FLANGE structure of clamping hoop type valve is provided, the pressure testing cost that this structure efficiently solves clamping hoop type valve is high, the problem that sealing effectiveness is poor, serviceable life is short, security is low.
The object of the present invention is achieved like this:
A kind of PRESSURE TESTING BLIND FLANGE structure of clamping hoop type valve, comprise test valve, blind plate main body, O type circle and blind plate O type circle, the pressure testing port of test valve is coaxially pressed with a blind plate main body by pressure testing machine, this blind plate main body middle part is coaxially shaped with pressure testing passage, and the blind plate main body outer wall in this pressure testing passage outside is coaxially embedded with an O type circle; The outer middle side part of blind plate main body is coaxially installed with a blind plate O type circle, it is characterized in that: blind plate main body middle inside described and test valve contact position is coaxially embedded with the sealing gasket of a nylon material, sealing pad is shaped with taper plush copper, and the test port of test valve is shaped with the conical socket coordinating with sealing gasket.
And, between described sealing gasket and blind plate main body, be embedded with a sealing gasket O type circle.
Advantage of the present invention and good effect are:
1, its sealing gasket of this structure contacts with the snap-ring groove of valve body and is static seal, and handling are simple.
2, the utility model design science, simple in structure, reliable operation, processing is simple, adopts nylon material, has good sealing function, has greatly increased the life-span of O-ring seal, can be widely used in clamping hoop type value pressure test.
Accompanying drawing explanation
Embodiment
Below in conjunction with accompanying drawing 1, embodiment of the present utility model being further described, it should be noted that: the present embodiment is descriptive, is not determinate, can not limit protection scope of the present invention with this.
A kind of PRESSURE TESTING BLIND FLANGE structure of clamping hoop type valve, comprise test valve 1, blind plate main body 3, O type circle 4, blind plate O type circle 5, the pressure testing port of test valve is coaxially pressed with a blind plate main body by pressure testing machine (not shown), this blind plate main body middle part is coaxially shaped with pressure testing passage, and the blind plate main body outer wall in this pressure testing passage outside is coaxially embedded with an O type circle; The outer middle side part of blind plate main body is coaxially installed with a blind plate O type circle 5.
Innovative point of the present utility model is:
Blind plate main body middle inside described and test valve contact position is coaxially embedded with the sealing gasket 2 of a nylon material, and sealing pad is shaped with taper plush copper, and the test port of test valve is shaped with the conical socket coordinating with sealing gasket.
For erection & lift steadiness, between described sealing gasket and blind plate main body, be embedded with a sealing gasket O type circle 6.
Principle of work of the present invention is:
Pack sealing gasket O type circle into packing washer, be pressed into blind plate main body simultaneously, pack each O type circle into and be connected with testing machine, sealing gasket is connected with blind plate main body; Sealing gasket adopts nylon processing, and cost is lower.
Change gasket material into nylon and be connected with PRESSURE TESTING BLIND FLANGE simultaneously, be installed simple, safe and reliable, can be widely used in multiple valve testing machine.
Claims (2)
1. the PRESSURE TESTING BLIND FLANGE structure of a clamping hoop type valve, comprise test valve, blind plate main body, O type circle and blind plate O type circle, the pressure testing port of test valve is coaxially pressed with a blind plate main body by pressure testing machine, this blind plate main body middle part is coaxially shaped with pressure testing passage, and the blind plate main body outer wall in this pressure testing passage outside is coaxially embedded with an O type circle; The outer middle side part of blind plate main body is coaxially installed with a blind plate O type circle, it is characterized in that: blind plate main body middle inside described and test valve contact position is coaxially embedded with the sealing gasket of a nylon material, sealing pad is shaped with taper plush copper, and the test port of test valve is shaped with the conical socket coordinating with sealing gasket.
2. the PRESSURE TESTING BLIND FLANGE structure of clamping hoop type valve according to claim 1, is characterized in that: between described sealing gasket and blind plate main body, be embedded with a sealing gasket O type circle.
