Description

Universal rotation type governing valve with pressure regulation function

Technical Field

The utility model relates to the technical field of speed regulating valves, in particular to a universal rotating speed regulating valve with a pressure regulating function.

Background

The speed regulating valve is a combined valve formed by connecting a fixed-differential pressure reducing valve and a throttle valve in series. The throttling valve is used for adjusting the flow passing through, the fixed-differential pressure reducing valve automatically compensates the influence of load change, so that the pressure difference between the front and the back of the throttling valve is a fixed value, the influence of the load change on the flow is eliminated, the pressure between the front and the back of the throttling valve is respectively led to the right end and the left end of the valve core of the pressure reducing valve, when the load pressure is increased, the hydraulic pressure acting on the left end of the valve core of the pressure reducing valve is increased, the valve core moves to the right, the pressure reducing port is increased, the pressure drop is reduced, and the pressure difference of the throttling valve is kept unchanged; and vice versa.

The connection of governing valve and other pipelines is mostly the block, and consequently the connection of governing valve is unstable enough, can appear leaking the phenomenon, consequently need improve the mode of connecting for connect inseparabler.

SUMMERY OF THE UTILITY MODEL

The utility model aims to: in order to solve the above problems, a universal rotation type speed control valve having a pressure adjusting function is proposed.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the utility model provides an universal rotation type governing valve with pressure regulation function, includes the valve body, the lateral wall fixedly connected with side pipe of valve body, it has the lug to stand out on the outer wall of side pipe, the cover is equipped with the cover piece on the side pipe, the recess has been seted up in the cover piece, recess and lug sliding connection, be connected with the locating part on the cover piece, the lateral wall of cover piece articulates there is the swinging head, the side pipe block has the connecting pipe, the outer wall of connecting pipe and the inner wall of swinging head have seted up corresponding screw thread.

Preferably, the limiting part comprises a fixedly connected bent rod, and springs are welded between the side wall of the bent rod and the side wall of the bump.

Preferably, the bent rods are L-shaped, and a plurality of bent rods are distributed on the circumference of the side wall of the sleeve block.

Preferably, the inner wall of the groove is smooth and provided with a wear-resistant layer.

Preferably, an elastic gasket is arranged at the clamping position of the side pipe and the connecting pipe.

In summary, due to the adoption of the technical scheme, the utility model has the beneficial effects that:

1. this application can make the pocket block remove along the horizontal direction under the restriction of lug through promoting the pocket block, consequently the knee compresses the spring, move connecting pipe department until the rotating tube, can rotate the rotating tube, the rotating tube can with connecting pipe threaded connection under the effect of screw thread, make connecting pipe and side union coupling, under the effect of rotating tube, the connecting pipe can't break away from with the side union, the elasticity effect of cooperation spring makes the position of rotating tube remain stable.

2. This application is through the nest block under the restriction of lug and recess for the nest block can't rotate on the side pipe, consequently the nest block can only move in the horizontal direction, consequently the rotating-tube can not receive the influence and rotate along with it at pivoted in-process nest block.
