Abstract
The utility model relates to a telescopic joint structure of valve, including valve body, telescopic joint and the compression ring flange of gate valve, install a telescopic joint at valve body runner tip, the inboard one end of telescopic joint is coaxial penetrate the valve body in, the compression ring flange that with body seals be connected is equipped with at telescopic joint sleeve, it is equipped with that the clamping ring is sealed to be filled up to compress tightly the cover between inboard valve body of compression ring flange and telescopic joint, the system has annular sealed pad mounting groove in the valve body. The utility model discloses a telescopic joint is installed respectively to the valve body both sides, and telescopic joint sleeve be equipped with with body seals's compression ring flange, the distance at tensile properties regulating valve body both ends that can be through the telescopic joint, construction process is simplified to directness and tube coupling, the on -the -spot adjustment of being convenient for.
Description
Technical field
The utility model belongs to valve field, especially a kind of expansion joint structure of valve.
Background technique
At present, the valve products such as the gate valve that market is sold, stop valve, normally adopt sand casting, wax casting, Reform of Resin Sand Casting, precoated sand manufacture technics, the manufacturing procedure of its technique is numerous and diverse, and reject rate is high, and power consumption is large, required professional and technical personnel is many, and investment occupied fund is many.The key fitment casting of current gate valve is use exceedingly high stove to machine substantially, and pollute for soil, air and water source, valve manufacture does not all jump out the casting method of these highly energy-consumings for many years.
And in existing technique, the joint of valve gap and valve rod all needs machining, and coordinate Flange joint could by valve rod positioning and locking, technique be comparatively complicated, and require high to raw material, worker duration, working efficiency is lower.
The distance of existing gate valve body both sides is fixing, often needs to add Flange joint in addition when installing in the duct, makes installation technology complicated, is not easy to on-the-spot adjustment.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides that a kind of structure is simple, rationally distributed, good reliability, is easy to the expansion joint structure of the valve safeguarded.
The utility model solves its technical problem and takes following technological scheme to realize:
A kind of expansion joint structure of valve, it is characterized in that: comprise the valve body of gate valve, slip joint and trim ring flange, be provided with a slip joint in valve flowing channel end, the inner opposite end of slip joint coaxially penetrates in valve body, is set with the trim ring flange be connected with valve seal outside slip joint; Valve body inside trim ring flange and between slip joint clamping sleeve trim ring sealing gasket is housed; The sealing gasket mounting groove of annular is shaped with in valve body.
And described valve body is the valve body of gate valve, butterfly valve or ball valve.
And be shaped with setting-in bulge loop at trim ring flange, valve body is shaped with the embedded grooves arranged coordinated with setting-in bulge loop.
Advantage of the present utility model and good effect are:
Valve body both sides of the present utility model are separately installed with slip joint, and are set with the trim ring flange with valve seal outside slip joint, by the distance at the stretchability regulation valve body two ends of slip joint, directly can be connected with pipeline, simplify construction process, are convenient to on-the-spot adjustment.
Accompanying drawing explanation
Fig. 1 is the utility model structural blast figure.
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.
An expansion joint structure for valve, the present embodiment accompanying drawing adopts gate valve to be that example is described, and this expansion joint structure can be applied to polytype valves such as gate valve, butterfly valve, ball valve.
See accompanying drawing 1, comprise the valve body 5 of gate valve, slip joint 1 and trim ring flange 3, at the medium runner two ends of the valve body of gate valve, one slip joint 1 is all installed, the lateral ends of slip joint is shaped with the mounting flange 8 for connecting, the inner opposite end of slip joint coaxially penetrates in valve body, the trim ring flange 3 be connected with valve seal is set with outside this slip joint, to stretch the adjustment that coaxially to stretch in trim ring flange, by the length of stretching slip joint regulation valve body during installation, directly can use in the pipeline of multiple distance, construction process is simple, is convenient to on-the-spot adjustment.
In order to ensure the sealing of slip joint, the valve body inside trim ring flange and between slip joint clamping sleeve trim ring sealing gasket 4 is housed, and be shaped with in valve body annular sealing gasket mounting groove 6, prevent trim ring sealing gasket slip joint regulate in be moved.
For the ease of installing accurate positioning, be shaped with setting-in bulge loop 2 at trim ring flange, valve body is shaped with the embedded grooves arranged 7 coordinated with setting-in bulge loop.
Although disclose embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope not departing from the utility model and claims, various replacement, change and amendment are all possible, therefore, scope of the present utility model is not limited to the content disclosed in embodiment and accompanying drawing.
Claims (3)
