Position it is corresponding with the position of boss, the diameter of pressure release through hole is not more than the height of boss；Along circle on the outer wall of plunger boss
Circumferential direction is provided with groove a, and in groove a sealing ring is provided with；Groove a is located at the lower section of pressure release through hole.
The characteristics of this utility model, also resides in,
Connecting tube bottom is provided with boss, and connection pipe outer wall is along the circumferential direction provided with groove b, and groove b is located at the convex of connecting tube
Platform top, is socketed with successively from top to bottom pipe and down tube on the outer wall of connecting tube, upper pipe top is coated with plectane, upper pipe bottom
Interior screw thread is connected with down tube top male thread, and upper inside pipe wall bottom is along the circumferential direction provided with annular breach, annular breach upper surface
Concordant with groove b upper surfaces, down tube is located on the boss of connecting tube, and down tube top end face is concordant with groove b lower surfaces, groove b
Snap ring is inside provided with, the width of snap ring is not less than the width of groove b.
The diameter of connecting tube top through hole is not more than the diameter of plunger lower boss cross section.
The number of groove a is two.
Plunger is hollow structure.
Connecting tube bottom outer wall is provided with screw thread.
The beneficial effects of the utility model are to can be very good to control to open again by arranging pressure release through hole in connecting tube
The pressure discharged in well during well, reduces task difficulty；Because the shell for installing additional needs certain professional tool to dismantle, protect
Interior arrangement；The simple low cost of this apparatus structure also solves high cost when blocking well head using production tree, production tree simultaneously
Upper valve is subject to the problem stolen.

Specific embodiment
This utility model is described in detail with reference to the accompanying drawings and detailed description.
This utility model provide a kind of well head switchgear, as shown in figure 1, include plunger 1, the bottom of plunger 1 be boss, post
Plug 1 is socketed with connecting tube 2, and the inner space of connecting tube 2 is engaged with the profile of plunger 1, and the inwall of connecting tube 2 is convex with plunger 1
The outer wall of platform is brought into close contact；The top of connecting tube 2 is threadedly coupled with the top of plunger 1, pressure release is provided with the side wall of connecting tube 2 and is led to
Hole 2-1, the position of pressure release through hole 2-1 is corresponding with the position of boss, and the diameter of pressure release through hole 2-1 is not more than the height of boss；
Groove a1-1 is along the circumferential direction provided with the outer wall of the boss of plunger 1, in groove a1-1 sealing ring is provided with；Groove a1-1 is located at pressure release
The lower section of through hole 2-1.
The bottom of connecting tube 2 is provided with boss, and the outer wall of connecting tube 2 is along the circumferential direction provided with groove b2-2, and groove b2-2 is located at and connects
The boss top of adapter 2, is socketed with successively from top to bottom pipe 3 and down tube 4 on the outer wall of connecting tube 2, the top of upper pipe 3 is coated with
Plectane 6, screw thread is connected with the top male thread of down tube 4 in the bottom of upper pipe 3, and the inwall bottom of upper pipe 3 is along the circumferential direction provided with annular and lacks
