Abstract
The utility model relates to a combined telescopic valve, comprising a valve body, a valve plate arranged in a flow channel of the valve body through a valve rod, and a sealing valve seat which is arranged on one side of the flow channel of the valve body and is tightly matched with the periphery of the valve plate, wherein, the end surface point of one side of the valve body is provided with a sleeve tube of a telescopic joint by a connecting piece, and the telescopic joint is sheathed in a tube cavity of the sleeve tube. The sealing valve seat is pressed and arranged in an installing groove of the sealing valve seat processed on the end surface of the valve body by the sleeve tube of the telescopic joint. The utility model has the advantages that convenience is provided to the replacement of easy-damage pieces of valves, maintenance time is shortened, and the maintenance cost of users is effectively reduced in addition, to create conditions for continuous production.
Description
The utility model relates to a kind of telescopic valve, relates to a kind of composite extendible valve that has slip joint specifically.
Be at present the structural type of suit one slip joint in the prolonged section at valve flowing channel at widely used telescopic valve on the pipeline.Though the telescopic valve of above-mentioned this structure provides convenience for the installation adjustment of valve and the maintenance of pipeline, do not bring convenience for the replacing of valve internal easily damaged parts, particularly seal valve seat.When through after a while operation, when needing to change the valve internal easily damaged parts, only take the mode that valve is removed (then needing crane gear to cooperate for large-scale valve could remove) from pipeline is carried out the replacing of easily damaged parts, certainly will cause human and material resources and waste of time.
The purpose of this utility model just is to overcome above-mentioned deficiency of the prior art, and more science, reasonable of a kind of structure is provided, and is easily manufactured, and composite extendible valve for ease of maintenaince.
The purpose of this utility model can adopt following measure to realize:
Composite extendible valve of the present utility model comprises valve body, is installed in valve plate in the valve flowing channel by valve rod, and be arranged on valve flowing channel one side and with the leakproof fit seal valve seat of valve plate periphery; Place, one side end face of described valve body is equipped with a slip joint sleeve pipe that is set with slip joint in its tube chamber by link, and described seal valve seat is fitted in the seal valve seat mounting groove that processes on the valve body end face by the slip joint sleeve pipe.
Valve body in the utility model, slip joint sleeve pipe and be sleeved in the slip joint sleeve pipe slip joint by be arranged on its separately flange plate and connecting screw rod, the stop nut on the body combine.
Valve of the present utility model is after operation after a while, when needing to change seal valve seat, only need to be positioned at stop nut on the connecting screw rod by adjusting, ordering about the slip joint sleeve pipe separates with valve body, and along connecting screw rod, move certain distance (this distance is advisable so that the maintenance person arm is entered) behind the flexible pipe joint face, just can easily old seal valve seat be taken out, after treating that new seal valve seat is packed into, be positioned at stop nut on the connecting screw rod by reverse adjusting, order about the slip joint sleeve pipe and in face of connecting screw rod and flexible pipe joint, move, after slip joint sleeve pipe and valve body are combined closely, get final product.
Advantage of the present utility model is: the replacing that not only can be the valve easily damaged parts is provided convenience; In addition, because between valve body of the present utility model and the expansion device is made up of slip joint sleeve pipe, slip joint is split-type structural, can realize the independent maintenance or the replacing of valve body or expansion device in actual use, can greatly shorten engineering time, create conditions for producing continuously, and can effectively reduce user's maintenance cost.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a plan view of the present utility model.
Fig. 2 is that the A of Fig. 1 is to view (symmetrical sectional view).
The utility model is done with detailed description below with reference to embodiment's (accompanying drawing):
As shown in the figure, composite extendible valve of the present utility model comprises valve body (1), be installed in the interior valve plate (3) of valve flowing channel by valve rod (2), and be arranged on valve flowing channel one side and with the peripheral leakproof fit seal valve seat of valve plate (3) (4), and the expansion device of forming by slip joint sleeve pipe (5), slip joint (6); Valve body wherein (1), slip joint sleeve pipe (5) and be sleeved on slip joint (6) in the slip joint sleeve pipe (5) flange plate on the body and connecting screw rod (7), stop nut (8) combine separately by being arranged on it; Described seal valve seat (4) is fitted in the seal valve seat mounting groove that processes on valve body (1) end face by the slip joint sleeve pipe (5) that combines with valve body (1) one side end face.
Claims (2)
1, a kind of composite extendible valve, it comprises valve body (1), be installed in the interior valve plate (3) of valve flowing channel by valve rod (2), and be arranged on valve flowing channel one side and with the peripheral leakproof fit seal valve seat of valve plate (3) (4), it is characterized in that: place, a side end face of described valve body (1) is equipped with a slip joint sleeve pipe (5) that is set with slip joint (6) in its tube chamber by link, and described seal valve seat (4) is fitted in the seal valve seat mounting groove that processes on valve body (1) end face by slip joint sleeve pipe (5).
2, composite extendible valve according to claim 1 is characterized in that: valve body (1), slip joint sleeve pipe (5) and be sleeved in the slip joint sleeve pipe (5) slip joint (6) by be arranged on its separately flange plate and connecting screw rod (7), the stop nut (8) on the body combine.
