Abstract

The utility model discloses a hand wheel controllable high pressure valve. The utility model is composed of a valve rod, a valve cover, a valve body, a protecting cover and a fixing screw, wherein, locking mechanisms are arranged on the valve rod and the valve cover; each of the locking mechanism is composed of a slide block, a clamp spring and a locking nut; a seal ring used on the valve body is vulcanized on a T-shaped ferrule by H-shaped rubber. The utility model has the advantages that a valve switch and the opening degree thereof are controlled by a locking device, unfamiliar people can not carry out the operation of opening and closing the value, and the utility model uses a novel rubber ring with simple structure, good sealing effect and long service life.

Description

Handwheel controllable type high pressure valve

The utility model relates to a kind of valve, particularly a kind of handwheel controllable type high pressure valve.

At present there are two shortcomings in the hand-wheel-type high pressure valve that uses at the scene: the one, and the handwheel of valve can arbitrarily be rotated by anyone, will cause like this in some important places, owing to layman's misoperation causes unnecessary trouble; The 2nd, it is square or oval-shaped steel ring sealing that the hand-wheel-type high pressure valve adopts the cross section, and the phenomenon of seepage, bad valve body of thorn in use takes place this steel ring easily, makes valve can not continue to use.

The purpose of this utility model just provides a kind of reliable sealing handwheel controllable type high pressure valve.

The purpose of this utility model is achieved in that handwheel controllable type high pressure valve is made up of valve rod, valve gap, valve body, guard shield and retaining screw, on valve rod and valve gap, be provided with locking framework, locking framework is made up of slide block, jump ring, locking nut, slide block is " E " font, second boss of slide block is thread form, have the longitudinal sliding block groove on the valve rod, valve gap is interior except that having the longitudinal sliding block groove, also have two with the wide circular groove of slide block boss, slide block is contained in the groove of valve rod and valve gap, have groove on the locking nut, it is fixed on the valve gap by jump ring.The seal ring that uses on the valve body be by the vulcanization of rubber of " H " type on the T-shape metal ring.

The utlity model has following advantage: 1, valve ON/OFF and open degree are controlled by locking device, and unfamiliar people can't carry out the valve switch operation; 2, adopt the new type rubber circle, simple in structure, good sealing effect, long service life.

Fig. 1: handwheel controllable type high pressure valve structural representation;

Fig. 2: valve rod lock state schematic representation; Fig. 3: valve rod opening state schematic representation;

Fig. 4: the sectional view of seal ring 6;

Among the figure: 1-valve rod, 2-slide block, 3-jump ring, 4-locking nut, 5-valve gap,

Delta bolt, 8-valve body, 9-flange, 10-guard shield and retaining screw in 6-seal ring, the 7-;

Below in conjunction with accompanying drawing the utility model is described further:

As shown in Figure 1, handwheel controllable type high pressure valve is by valve rod 1, valve gap 5, valve body 8, guard shield and retaining screw 10 are formed, on valve rod 1 and valve gap 5, be provided with locking framework, as shown in Figure 2, locking framework is by slide block 2, jump ring 3, locking nut 4 is formed, slide block 2 is " E " font, second boss of slide block 2 is thread form, on valve rod 1 and valve gap 5, have the longitudinal sliding block groove, in the valve gap 5 except that having the longitudinal sliding block groove, also have two with the wide circular groove of slide block boss, slide block 2 is contained in the groove of valve rod 1, also have groove on the locking nut 4, it is fixed on the valve gap 5 by jump ring 3.The seal ring 6 that uses on the valve body 8 be by the vulcanization of rubber of " H " type on the T-shape metal ring, as shown in Figure 4, when fluctuation takes place in the working pressure of high-pressure medium, the medium working pressure acts on the lip of seal ring " H " type rubber simultaneously, make on its sealing surface that is attached to flange 9 and valve body 8 tightly, and the T-shape metal ring bears the pressure of seal ring, prevents that rubber from embedding in the slit of flange 9 and valve body 8 thereby its good sealing effect, long service life.

Locking nut 4 is to be on second boss of slide block 2 at ordinary times, as shown in Figure 2, pins the thread form groove of 2 second boss of slide block, makes the slide block 2 can not axial float, and valve rod 1 also just can not rotate.When need opening, as long as regulate locking nut, when the top slide block groove of groove on the locking nut 4, valve gap 5 is alignd with slide block 2, as shown in Figure 3, at this moment slide block 2 just can enter in the circular groove of valve gap 5 by locking nut 4, and valve rod 1 also just can not be subjected to the restriction of slide block, and valve is in opening state.

Claims

1, a kind of handwheel controllable type high pressure valve is by valve rod (1), valve gap (5), valve body (8), guard shield and retaining screw (10) are formed, it is characterized in that: on valve rod (1) and valve gap (5), be provided with locking framework, locking framework is by slide block (2), jump ring (3), locking nut (4) is formed, slide block (2) is " E " font, second boss of slide block (2) is thread form, valve rod has the longitudinal sliding block groove on (1), valve gap (5) is interior except that having the longitudinal sliding block groove, also have two with the wide circular groove of slide block boss, slide block (2) is contained in the groove of valve rod (1) and valve gap (5), locking nut has groove on (4), and it is fixed on the valve gap (5) by jump ring (3).

2, handwheel controllable type high pressure valve according to claim 1, it is characterized in that seal ring (6) that described valve body (8) go up to use be by the vulcanization of rubber of " H " type on the T-shape metal ring.
