Abstract
This utility model provides a kind of stop valve, including valve body, spool and the valve rod driving valve core movement, described valve inner is provided with the keying mouth coordinated with spool and is embedded in the copper sheathing opened and closed on mouth, described spool is positioned at above copper sheathing and opens and closes with copper sheathing and coordinates, described stop valve also includes the screw connecting valve rod and the contiguous block of spool and fixing contiguous block with spool, described contiguous block is set on valve rod, described spool is positioned at below contiguous block, such assembling mode simple and fast, reduce requirement on machining accuracy and decrease manufacturing procedure, so cost-effective.
Description
Technical field
This utility model relates to valve field, particularly relates to a kind of stop valve.
Background technology
As it is shown in figure 1, the stop valve of prior art includes the spool 1 ' cooperated and valve rod 2 ' and the steel ball 3 ' being connected spool and valve rod.Described spool is provided with mounting groove 4 ', the first annular groove 5 ' being used for accommodating steel ball and the insertion hole 6 ' installed for steel ball and connect with first annular groove inserted for valve rod.Described valve rod is provided with and the second annular groove 7 ' of first annular groove fit receiving steel ball.In the insertion hole of described spool, the screw 8 ' for blocking steel ball is installed.Above-mentioned stop valve processing technique is complex and high cost；Spool is big with the assembly difficulty of valve rod, high to the requirement on machining accuracy of part.
In consideration of it, be necessary to design a kind of stop valve to solve the problems referred to above.
Utility model content
The technical problems to be solved in the utility model is: provides a kind of and assembles simple and that processing technique is few stop valve.
For reaching above-mentioned purpose, this utility model provides following technical scheme: a kind of stop valve, including valve body, spool and the valve rod driving valve core movement, described valve inner is provided with the keying mouth coordinated with spool and is embedded in the copper sheathing opened and closed on mouth, described spool is positioned at above copper sheathing and opens and closes with copper sheathing and coordinates, described stop valve also includes the screw connecting valve rod and the contiguous block of spool and fixing contiguous block with spool, and described contiguous block is set on valve rod, and described spool is positioned at below contiguous block.
Further, described contiguous block includes the fixing hole that the installing hole coordinated with valve rod and some confession screws insert, and described fixing hole is round described installing hole.
Further, one end that described valve rod coordinates with contiguous block is convexly equipped with into hemispheroidal fixed part, and described fixed part coordinates with the installing hole of contiguous block.
Further, being provided with sealing gasket below described spool, described sealing gasket is between spool and copper sheathing.
Further, described stop valve also includes the valve gap being arranged on valve body, and the lower section of described valve gap is bolted on valve body；Described valve gap be arranged above valve stem nut, described valve rod is that screw pair coordinates with valve stem nut.
Further, described valve body includes being positioned at the inlet and outlet opening and closing mouth both sides.
Prior art is compared, this utility model at least has the advantage that by contiguous block sheathed on valve rod, then is fastened with spool by contiguous block by screw, such assembling mode simple and fast, reduce requirement on machining accuracy and decrease manufacturing procedure, so cost-effective.

Fig. 1 is the partial cutaway schematic of the stop valve of prior art.
Fig. 2 is that the master of stop valve of the present utility model regards generalized section.
Fig. 3 is the partial enlarged drawing of part A in the stop valve shown in Fig. 2.
Detailed description of the invention
Structure and the utility model content of stop valve of the present utility model are described below in conjunction with Fig. 2 to 3.
A kind of stop valve, the valve gap 2 including valve body 1, being arranged on valve body 1, is positioned at the spool 3 valve body 1 within, the valve rod 4 driving spool 3 to move up and down and the contiguous block 5 connecting spool 3 and valve rod 4.
Described valve body 1 is internal be provided with coordinates with spool 3 open and close mouth 6, be positioned at and open and close import 7 and the outlet 8 of mouth 6 both sides and be embedded in the copper sheathing 9 on keying mouth 6.
The lower section of described valve gap 2 is connected on valve body 1 by bolt 10.The valve stem nut 11 being arranged above fixing valve rod 4 of described valve gap 2.
Described spool 3 becomes flat, and it is between contiguous block 5 and copper sheathing 9.Described spool 3 is connected by screw 12 is fixing with contiguous block 5.Described spool 3 realizes opening and closing with copper sheathing 9 under the drive of valve rod 4 and coordinates.Below described spool 3, sealing gasket 13 is installed.Described sealing gasket 13 is between spool 3 and copper sheathing 9.
Described valve rod 4 one end coordinates for screw pair with valve stem nut 11, so can realize moving up and down.One end that described valve rod 4 coordinates with contiguous block 5 is convexly equipped with into hemispheroidal fixed part 14.Described fixed part 14 is for interfering the motion of contiguous block 5.
Circlewise, it includes the fixing hole 16 that the installing hole 15 being set on valve rod 4 and some confession screws 12 insert to described contiguous block 5.Described fixing hole 16 is round described installing hole 15.Described fixed part 14 coordinates with installing hole 15.
The installation method of stop valve of the present utility model is as follows: be first set on valve rod 4 by contiguous block 5；Then spool 3 is fixed on by screw 12 lower section of contiguous block 5；Again valve rod 4 is fixed on valve stem nut 11；Finally valve gap 2 is fixed on valve body 1 by bolt 10.When rotation valve rod 4, spool 3 moves up and down, and plays, with copper sheathing 9, the effect of opening and closing.Assembling simple and fast of the present utility model, decreases processing technique, and then reduces cost.
In sum, these are only preferred embodiment of the present utility model, scope of the present utility model should not limited with this.The most every simple equivalence change made according to this utility model claims and description with modify, all should still belong in the range of this utility model patent contains.
