The utility model solves its technical problem and takes following technological scheme to realize:
a kind of container conduit on-Line Monitor Device pet valve, comprise valve body, the body connecting head, valve rod, valve wheel and identification disc, valve body lower end is coaxially installed with a body connecting head, this body connecting head is communicated with made valve pocket in valve body, the coaxial valve rod that vertically is equipped with in valve body, this valve rod upper end is stretched out valve body and be coaxially installed with a valve wheel that is used for the regulating valve stem switch on valve rod, be coaxially installed with the identification disc of a convenient operation personnel control pet valve working state on the valve body of valve wheel below, it is characterized in that: described valve body both sides are symmetrical respectively to be fixed with the detection cut-off joint that is communicated with valve pocket and to test cut-off joint.
And, described detection cut-off joint is identical with test cut-off joint structure, comprise shell, pressing plate, spring, spool and push rod and seal ring, the end that shell is connected with valve body is fixed with a back-up ring, the other end inside of shell is shaped with an annular convex shoulder, enclosure between from the back-up ring to the annular convex shoulder coaxial order successively is equipped with pressing plate, spring, spool and push rod, and this push rod stretches out annular convex shoulder, and the surface of contact of the spool outside and shell is coaxially installed with a seal ring.
And, on the valve rod of described valve wheel lower end, a left-hand thread locknut is installed.
Advantage of the present utility model and good effect are:
1, this pet valve is symmetrically arranged with cut-off joint, the convenient data demonstration of commutation being installed and observing monitoring device.
2, this pet valve is equipped with the left-hand thread locknut, can prevent malfunction or change because vibrations cause valve position, guarantees handling safety.
3, this pet valve is the width screw thread and coordinates the ball needle construction to make the switch rotary angle little, and is swift to operate, saves time, and promotes to detect operating efficiency.
4, simple in structure, the design science of the utility model, simple operation, do not need the on-Line Monitor Device on the dismounting container conduit, test that can the finishing equipment Test item.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 cuts open structural representation in cut-off joint in the utility model;
Fig. 3 is the upper floor map of valve wheel in the utility model;
Fig. 4 is floor map on identification disc in the utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by specific embodiment, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of container conduit on-Line Monitor Device pet valve, as accompanying drawing 1 to as shown in accompanying drawing 4, comprise valve body 7, body connecting head 10, valve rod 5, valve wheel 2, identification disc 6, detect cut-off joint 1 and test cut-off joint 8, valve body lower end is coaxially installed with a body connecting head, above-mentioned coaxial being arranged on the equipment container main pipe of body connecting head during use; This body connecting head is communicated with made valve pocket 9 in valve body, the coaxial valve rod that vertically is equipped with in valve body, this valve rod upper end is stretched out valve body and be coaxially installed with a valve wheel that is used for the regulating valve stem switch by gland bolt 4 on valve rod, rotate this valve wheel actuatable valve bar and move up and down, valve rod moves down and can block the made through hole that is connected with the body connecting head of valve body lower end; Be coaxially installed with the identification disc of a convenient operation personnel control pet valve working state on the valve body of valve wheel below.
The valve body both sides are symmetrical detection cut-off joint and the test cut-off joint that is communicated with valve pocket that be fixed with respectively, detects cut-off joint and is used for being connected with on-Line Monitor Device, keeps real time on-line monitoring; The test cut-off joint is used for joint test instrument, sampling connection, external monitoring device etc.
Described detection cut-off joint is identical with test cut-off joint structure, as shown in Figure 2, comprise shell 14, pressing plate 17, spring 16, spool 11 and push rod 12 and seal ring 15, the end that shell is connected with valve body is fixed with a back-up ring 18, the other end inside of shell is shaped with an annular convex shoulder 13, enclosure between from the back-up ring to the annular convex shoulder coaxial order successively is equipped with pressing plate, spring, spool and push rod, this push rod stretches out annular convex shoulder, and the surface of contact of the spool outside and shell is coaxially installed with a seal ring.
