Between portion；The end set of described screw rod has pointer set, and the end of pointer set overlaps with the outer wall section of valve body, outside valve body
It is provided with graduated scale on wall, the end of pointer set indicating graduation on the scale.
The end of described pointer set is provided with chamfering.Baffle ring is provided with the inside of described screw rod end, baffle ring is by hair
Felt into.
The beneficial effects of the utility model are：
1st, the utility model employs rubber as encapsulant, instead of polytetrafluoroethylmaterial material of the prior art,
While ensure that sealing effectiveness, the drawbacks of seal spool part is plastically deformed is eliminated.It is easy in order to solve rubber seal
Rubber bodies vulcanization is connected on a steel loop by the problem of coming off, the utility model.
2nd, seal spool part is arranged on valve seat by the utility model by the form of clamping, after rubber bodies damage, is only needed
The rubber bodies of damage are removed together together with steel loop by replacing by instrument, therefore are easily fitted in the absence of seal spool part
The problem of being difficult to dismounting on valve seat.
3rd, the setting of pointer set, can be indicated the deformation quantity of spring, so as to preset pressure of the present utility model
Indicated, so as to realize that basic preset pressure indicates work instead of pressure gauge when pressure gauge damages.
4th, spring has been arranged between the end face of valve rod and the bottom of described blind hole by the utility model, with prior art
Middle to compare structure type of the spring housing on valve rod, the structure type that the utility model uses is by enclosing springs in an envelope
In the space closed, without exposure in media as well, so as to avoid influenceing the accuracy of preset pressure value because spring is corroded.
5th, the setting for the chamfering that pointer is put so that the sight of people is easier to align with graduation mark, reading of being more convenient for.
