The utility model discloses a design and the sealed form of former union have been changed to the device, have increased the seal groove of union sealing washer to increased pressure testing / pressure release hole and pressure release end cap, neither influenced its original each item service function, again can be quicker tear open, the charge of oil mouth, reduce the processing part, realized the no pressure of operation department, realized tearing, adorn the renewal part open conveniently fast, satisfied all service function totally.

Description

A kind of fast assembling-disassembling fixation type throttle valve

Technical field

The utility model belongs to mechanical equipment technical field, relates to a kind of fast assembling-disassembling fixation type throttle valve.

Background technique

Fixation type throttle valve is applied very extensive in the every fluid operation in oil field, and being mainly used in the equipment such as oil well head oil recovery (gas) tree, manifold, is the control unit controlling fluid changes in flow rate.

At present, fixation type throttle valve the most frequently used both at home and abroad, its structure seals with plug in cavity, fastening project organization is carried out again by union, when throttling latus rectum need be adjusted change oil nozzle, cavity exists pressure to be made plug not quick detachable and there is severe compromise, and O RunddichtringO affects comparatively large by machining accuracy, not easily meet sealing effect; In addition, when needing the throttle element oil nozzle changing throttling latus rectum, the serious jam of plug is not quick detachable.

Model utility content

The purpose of this utility model is to provide a kind of fast assembling-disassembling fixation type throttle valve, solve in prior art and seal with plug in cavity, fastening project organization is carried out again by union, when throttling latus rectum need be adjusted change oil nozzle, cavity exists pressure to be made plug not quick detachable and there is severe compromise, O RunddichtringO affects comparatively large by machining accuracy, not easily meet the problem of sealing effect.

The technological scheme that the utility model adopts is, a kind of fast assembling-disassembling fixation type throttle valve, is provided with oil nozzle in the inlet passage of threeway; To be threaded union to straight service aisle mouth at the inlet passage of threeway, the axle center hole of union is provided with pressure release plug, and in union, bottom is provided with union seal ring.

Fast assembling-disassembling fixation type throttle valve of the present utility model, is further characterized in that:

Oil nozzle is provided with different size.

The beneficial effects of the utility model are, have changed design and the seal form in reason ninth of the ten Heavenly Stems, add the seal groove of union seal ring, and add pressure testing/relief hole and pressure release plug thereof, neither affect its original every using function, again can disassemble or assemble oil nozzle faster; Decrease processing accessories, realize operation place without pressure, realize disassemble or assemble renewal part easily and fast, meet all using function completely.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

In figure, 1. union, 2. union seal ring, 3. pressure release plug, 4. threeway, 5. oil nozzle.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.

With reference to Fig. 1, structure of the present utility model is, in the inlet passage of threeway 4, be provided with oil nozzle 5, and oil nozzle 5 is provided with different specifications as required; To be threaded union 1 to straight service aisle mouth at the inlet passage of threeway 4, the axle center hole of union 1 is provided with pressure release plug 3, and in union 1, bottom is provided with union seal ring 2, and union seal ring 2 is for the sealing of union 1 with service aisle mouth.

Innovative point structure of the present utility model is within dotted line frame in Fig. 1.

Working principle of the present utility model is,

In actual mechanical process, when needs change fluid flow, when just must change the oil nozzle 5 of different latus rectum, open pressure release plug 3, lay down the pressure in threeway 4, then dismantle union 1 and carry out working service, change union seal ring 2 or oil nozzle 5, after changing union seal ring 2 or oil nozzle 5, screw union 1, and close pressure release plug 3, can pressure duty be reentered.

Claims (2)

1. a fast assembling-disassembling fixation type throttle valve, is characterized in that: in the inlet passage of threeway (4), be provided with oil nozzle (5); At the inlet passage of threeway (4), straight service aisle mouth is threaded union (1), the axle center hole of union (1) is provided with pressure release plug (3), is provided with union seal ring (2) in the interior bottom of union (1).
